Abstract
Postpartum acute kidney injury (AKI) is a condition characterized by a sudden and rapid decline in kidney function that occurs shortly after childbirth. Several risk factors may be associated with postpartum acute kidney injury (AKI). Understanding the possible risk factors is essential for timely intervention and improved maternal healthcare. The aim of the study was to assess the risk factors of postpartum acute kidney injury patients. This prospective observational study took place at Mymensingh Medical College Hospital, from March 2020 to April 2021. It was carried out in the Departments of Nephrology and Departments of Obstetrics & Gynecology, where 153 postpartum acute kidney injury (AKI) patients were enrolled through purposive sampling. The study collected data on patient demographics, etiology and presentation. Statistical analysis was conducted using SPSS (Statistical Package for the Social Sciences) version 26.0, with a significance threshold set at p<0.05 for all tests. Among participants, puerperal sepsis (77.8%) and toxemia of pregnancy (58.8%) were prevalent risk factors. Intrauterine death was rare (1.3%). Other risk factors such as postpartum hemorrhage 22.2%, HELLP syndrome 11.1%, and antepartum hemorrhage 15.0% were found. A statistically significant difference in postpartum hemorrhage prevalence (p=0.038) was noted between hemodialysis and non-hemodialysis patients. Puerperal sepsis is the most common risk factor for postpartum acute kidney injury, closely followed by toxemia of pregnancy. Intrauterine death is rare, while postpartum hemorrhage significantly affects subjects, with variations noted between hemodialysis and non-hemodialysis patients.

Abstract
Flavonoids are organic compounds characterized by a range of phenolic structures, which are abundantly present in various natural sources such as fruits, vegetables, cereals, bark, roots, stems, flowers, tea, and wine. The health advantages of these natural substances are renowned, and initiatives are being taken to extract the flavonoids. Apigenin, galangin, hesperetin, kaempferol, myricetin, naringenin, and quercetin are the seven most common compounds belonging to this class. A thorough analysis of bibliographic records from reliable sources including Google Scholar, Web of Science, PubMed, ScienceDirect, MEDLINE, and others was done to learn more about the biological activities of these flavonoids. These flavonoids appear to have promising anti-diabetic, anti-inflammatory, antibacterial, antioxidant, antiviral, cytotoxic, and lipid-lowering activities, according to evidence from in vitro, in vivo, and clinical research. The review contains recent trends, therapeutical interventions, and futuristic aspects of flavonoids to treat several diseases like diabetes, inflammation, bacterial and viral infections, cancers, and cardiovascular diseases. However, this manuscript should be handy in future drug discovery. Despite these encouraging findings, a notable gap exists in clinical research, hindering a comprehensive understanding of the effects of flavonoids at both high and low concentrations on human health. Future investigations should prioritize exploring bioavailability, given the potential for high inter-individual variation. As a starting point for further study on these flavonoids, this review paper may promote identifying and creating innovative therapeutic uses.

Abstract
All over the world, technology is becoming more and more prevalent in agriculture. Different types of instruments are already being used in this sector. For the time being, every farmer is trying to produce more crops on a piece of land. Eventually, soil loses its nutrients; however, to grow more crops, farmers use more fertilizers without knowing the proper conditions of the soil in real time. To overcome this issue, many scientists have recently focused on developing electrochemical sensors to detect macronutrients, i.e., nitrogen (N), phosphorus (P), and potassium (K), in soil or water rapidly. In this review, we focus mainly on the recent developments in electrochemical sensors used for the detection of nutrients (NPK) in different types of samples. As it is outlined, the use of smart and portable electrochemical sensors can be helpful for the reduction of excess fertilizer and can play a vital role in maintaining suitable conditions in soils and water. We are optimistic that this review can guide researchers in the development of a portable and suitable NPK detection system for soil nutrients.

Abstract
Magnesium (Mg) has important effects on vascular system and deficiency of this cation is thought to be a risk factor for cerebrovascular atherosclerosis and complications. The study was planned to find out the association of serum magnesium level with severity of neurological disability in patient with acute ischemic stroke. This cross-sectional descriptive study was conducted in the department of Neurology and Medicine at Mymensingh Medical College & Hospital, Mymensingh from June, 2018 to October, 2019. Patients with acute ischemic stroke were evaluated following informed written consent. Diagnosis was confirmed by neuroimaging of brain. Moreover, serum magnesium assay was done for each patient. Data were collected by interview, clinical examination and laboratory investigations of patients using a case record form and analysis was carried out by using the SPSS 22.0 (IBM Inc., Armonk, NY, USA). Mean age of acute ischemic stroke patients was 63.94±13.93 years with male predominance (58.30%). Majority of the respondents (70.2%) had NIH Stroke Scale (NIHSS) score 5-15 (moderate stroke), 13.1% had score 1-5 (minor stroke), 13.1% had score15-20 (Moderate to severe stroke) and 3.6% had score 21-42 (severe stroke). Mean serum magnesium level was 1.83±0.283mg/dl. Hypomagnesaemia was present in 28(33.3%) patients and it was related with higher NIHSS scoring (p<0.05). Multiple regression showed that among the risk factors, serum magnesium level was independently associated with severity of neurological disability of the acute ischemic stroke (p<0.001). In this study, the correlation coefficient between serum magnesium level and NIHSS score was found as r= - 0.667 which showed negative relationship between serum magnesium and NIHSS score. Lower serum magnesium level is associated with the severity of neurological disability of acute ischemic stroke patient. Further case-control studies are required to validate this finding.

Abstract
This paper reports the study of hollow microballoon-filled epoxy composites also known as syntactic foams with various volume fractions of microballoons. Different mechanical and thermomechanical investigations were carried out to study the elastic and viscoelastic behavior of these foams. The density, void content, and microstructure of these materials were also studied for better characterization. In addition to the experimental testing, a representative 3D model of these syntactic foams was developed to further investigate their elastic behavior. The results indicate that changes in the volume percentage of the microballoons had a substantial impact on the elastic and viscoelastic behavior of these foams. These results will help in designing and optimizing custom-tailored syntactic foams for different engineering applications.

Abstract
When healthy women undergo caesarean section (CS) under sub arachnoid anaesthesia, transient electrocardiographic changes, such as ST-segment depression and T-wave abnormalities, are observed. During an elective caesarean section under sub arachnoid anaesthesia, about one-third of healthy parturient experience chest pain and ECG changes suggestive of myocardial ischemia. To assess the ST-segment and Rate Pressure Product changes with chest pain in patients with elective caesarean section under subarachnoid block. The Department of Anesthesia, Analgesia and Intensive Care Medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh was the site of this prospective observational study. The study included 86 healthy women between the ages of 20 and 35 who needed an elective caesarean section under a single shot sub arachnoid block and who visited the Department of Anesthesia, Analgesia, and Intensive Care Medicine at BSMMU in Shahbagh, Dhaka from January 2019 to June 2019. In comparison to the no chest pain group, ST-segment changes among the chest pain group at delivery, 5 minute, 10 minute after delivery and at the end of the surgery were highly significant (p=0.001). Comparatively, Rate Pressure Product changes were found to be significantly higher in the group with chest pain than in the group without chest pain (p=0.001). It is concluded that there is a substantial association of chest pain with rate pressure product and ST-segment changes after subarachroid block in caesarean section.

Abstract
Stroke is one of the leading causes of mortality and morbidity all over the world. The economic cost for stroke disability and post stroke rehabilitation is a growing concern. Ischemic stroke comprises 80.0 - 85.0% of total stroke cases caused by thrombotic or embolic occlusion of cerebral arteries. The source of embolism may be a larger artery or cardiac. Overt heart failure is an independent predictor of long term unfavorable functional outcome in stroke patients. However, there is little research whether the acute ischemic stroke risk is associated with mild to moderate degree of Left Ventricular Systolic Dysfunction (LVSD). This study was aimed to investigate the relation between LVSD and acute ischemic stroke (AIS) and to evaluate the relation between left ventricular systolic dysfunction and severity of neurological deficits after acute ischemic stroke. This case-control study was carried out in the Department of Neurology and Department of Medicine, Mymensingh Medical College and Hospital, Bangladesh from January 2019 to December 2020. One hundred twenty (120) patients of first ever AIS and 120 age and sex matched apparently healthy controls were enrolled in the study. Severity of stroke was measured by National Institute of Health Stroke Scale (NIHSS). Left ventricular (LV) systolic function was assessed by transthoracic 2-dimensional echocardiography. Mean±SD age was 58.23±9.34 years and 55.92±9.72 years respectively in cases and controls. Male to female ratio was 1.86:1. Left ventricular systolic dysfunction of any degree was more frequent in stroke patients (23.3%) than in controls (5.8%; p<0.001). The mean±SD of LVEF were 59.21±9.68 and 63.54±6.84 among case and control groups respectively. Mild LV dysfunction was observed 16.7% in AIS patients and 5.8% in control group. Moderate LV dysfunction was found in 6.7% in AIS patients. Participants with mild LVSD had significantly higher odds of being in the cases compared to participants with no LVSD (OR: 3.48; 95% CI: 1.41-8.59). Similarly, participants with moderate LVSD were 9.74 times more likely to be in ischemic stroke group compared to participants with no LVSD (OR: 9.74; 95% CI:1.19-19.29). LVSD was associated with AIS even after adjusting for other stroke risk factors (OR: 2.7462; 95CI for OR: 1.0204, 7.3906; p=0.0435). The NIHSS was significantly negatively correlated with LVEF (r=-0.443; p<0.001). The study may conclude that Left ventricular systolic dysfunction of mild to moderate degree, is associated with acute ischemic stroke. AIS patients with higher neurological deficit also had lower LVEF.

Abstract
A major global public health concern is the prevalence of diabetes mellitus, especially in developing countries like Bangladesh. While still battling communicable diseases, Bangladesh is already inundated with non-communicable diseases. Type 2 diabetes has been found in almost 90.0% of all instances of diabetes. The main risk factors for type 2 diabetes are an excessively caloric diet, advanced age, sedentary behavior and obesity. Along with preexisting risk factors, many micro-nutrients have been related to a rise in the incidence of diabetes. The study's objective was to measure and contrast the zinc levels in serum between individuals with type 2 diabetes mellitus and healthy controls. This cross-sectional study was conducted from July 2018 to June 2019 at the Mymensingh Medical College, Mymensingh, Bangladesh. Based on inclusion and exclusion criteria, the subjects were chosen using a purposeful (non-random) sample method. In total, 100 people participated in this study. They were divided into two groups: 50 individuals who had been diagnosed with type 2 diabetes mellitus were chosen as cases and 50 individuals who appeared to be in generally excellent health were chosen as controls. For the analytical aims of this investigation, serum zinc levels were examined. All values were expressed as the mean SD. The statistical analyses were carried out using the Windows program statistics package for social science (SPSS). The statistical significance of the difference between the case and control groups was evaluated using the Student's unpaired 't' test. A thorough research revealed that type 2 diabetes mellitus patients had significantly lower mean serum zinc levels than healthy controls (case group was 110.96±13.60 and control group 130.18±9.95μg/dl). Cross-sectional research was used in this study. The current study's findings showed that type 2 diabetes mellitus patients had dramatically changed serum zinc levels. The study's hypothesis was verified as a result.

Abstract
As limited or no studies on pro-inflammatory cytokines (IL-1, IL-6, TNF-α)) and anti-inflammatory cytokines (IL-4, IL-10, IL-13) were reported in type 2 diabetes mellitus (T2DM) from Bangladesh. This case-control prospective interventional study was therefore undertaken to ascertain the status of them newly diagnosed Bangladeshi patients with T2DM at Medical Research Unit (MRU), MCW&H Building, MHWT, Uttara, Dhaka, Bangladesh from July 2018 to June 2021. Suspected patients with T2DM had undergone oral glucose tolerance test (OGTT) after overnight fasting. Blood samples were collected from patients at 'O' minute (Fasting) and at 2Hr (120 min) of OGTT. Newly OGTT positive 36 adult Bangladeshi patients (Male: 15, Female: 21, Age range: 35-65 years; mean±SD: 47±18 years) and 30 normal healthy subjects (Male: 12, Female: 18; Age range: 32-67 years; mean ±SD: 45±16 years) were included in the study. Serum levels of pro-inflammatory and anti-inflammatory cytokines were determined by enzyme immunoassay methods using research kits obtained from reputed companies at Medical Research Unit laboratory, Uttara, Dhaka, Bangladesh; Fasting serum levels of pro-inflammatory cytokines (IL-1, IL-6, TNF-α) were much elevated in patients compared to controls by Students t-test (p<0.001); At 2Hr of OGTT, the serum levels of these cytokines in patients remained elevated even at 2Hr of OGTT compared to their fasting levels (p<0.001). Among the anti-inflammatory cytokines, serum IL-4 level was found to be higher in patients compared to controls (p<0.05). Interestingly, F-IL-10 and F-IL-13 levels were significantly lower in patients compared to controls (p<0.001). These anti-inflammatory cytokines (IL-10 and IL-13) at 2Hr of OGTT also remained low among patients as revealed by Paired t-test (p?0.05); These results reported for the first time in Bangladeshi patients supported the concept that T2DM possibly develops due to imbalance among pro-inflammatory and anti-inflammatory cytokines. Further studies are warranted along this line involving more respondents.

Abstract
Guillain-Barre syndrome (GBS) is an acute autoimmune polyradiculoneuropathy. Neutrophil-lymphocyte ratio (NLR) is a novel prognostic and inflammatory marker in patients with neurological diseases. The study was designed to observe the relation between neutrophil lymphocyte ratio and the clinical severity in patients with Guillain-Barre Syndrome (GBS). This cross-sectional descriptive study was conducted at the department of Neurology and Medicine, Mymensingh Medical College and Hospital from April 2019 to September 2020. Total 58 patients with GBS were enrolled according to the inclusion and exclusion criteria within 7 days of development of symptoms. The clinical diagnosis of GBS was done according to Ausbury and Cornblath's diagnostic criteria; moreover clinical severity was done according to Hughes and Rees scale, Medical Research Council (MRC) grade, cranial nerve involvement and autonomic involvement. After measuring complete blood count, NLR was calculated by dividing neutrophil count to lymphocyte count. Data analysis was done on SPSS 23.0. Mean age of the GBS patients was 36.21±11.55 years. Among 58 respondents 70.69% (41) were male and 29.31% (17) were female. Most of the patients had a GBS severity score of 4(62.07%) followed by 3(27.59%) and 5(10.34%). The mean NLR of the respondents was 3.22±2.25. Acute motor axonal neuropathy (AMAN) was in 48.28% respondents and their mean NLR was 3.89±0.31, 31.03% had AIDP and mean NLR was 3.28±0.46 and 20.69% had Acute motor sensory axonal neuropathy (AMSAN) and mean NLR was 4.5±0.52. The mean NLR of the MRC grade 0, 1, 2, 3 patients was 6.61±1.78, 3.39±0.92, 2.71±1.39 and 1.45±0.40 respectively. Hughes score had a positive correlation (r=0.5333 and p<0.01) and MRC grade had a negative correlation (r= - 0.76805 and p<0.01) with NLR. Severity of GBS was significantly associated with raised NLR. Increase Hughes and Rees scale and decrease MRC grade also related to increased NLR.

Abstract
When performing infra-umbilical procedures, caudal epidural analgesia with bupivacaine is frequently used to provide both intra- and post-operative analgesia. Dexmedetomidine, an alpha 2 agonistsare extensively used in neuraxial blocks and peripheral nerve blocks to prolong the action of bupivacaine. To find out the effects of dexmedetomidine as an adjuvant to bupivacaine for caudal analgesia in children undergoing infra-umbilical surgery. This was a randomized, controlled double-blinded prospective observational study and was performed from July 2019 to December 2019. A total of 60 (Sixty) patients with different infra-umbilical surgical problems underwent different procedure under caudal anaesthesia in different operation theatre in Bangabandhu Sheikh Mujib Medical University, Dhaka were enrolled in this study. Elaborate personal history, meticulous clinical examinations and relevant laboratory investigations was done. Post-operative adverse effects also were monitored. All information from history of illness, clinical, laboratory findings, duration of analgesia and post-operative adverse effects were recorded in a preformed data sheet (Appendix-I) and statistical analysis was done by SPSS 22.0. Mean age of the children in Group A (dexmedetomidine + bupivacaine) was 5.50±2.61 years and in Group B (bupivacaine) was 5.66±2.75. Mean weight of the children in Group A was 19.22±8.58 kg and in Group B was 19.70±8.94 kg in this study. Mean duration of anaesthesia was 27.5±6.5 minute in Group A and 28.5±5.5 minute in Group B. The mean duration of analgesia was 4.32±0.54 hours for Group A and 2.12±0.32 hours in Group B. In Group A, 46.7% patients required 1 and 3.3% required 2 rescue analgesic but in Group B, 43.3% patients required single rescue analgesic and 33.3% required two rescue analgesics (p<0.05). In Group A, 6.7% patients had nausea/ vomiting and in Group B, 16.7% patients had nausea/ vomiting (p>0.05). It can be concluded that dexmedetomidine with bupivacaine for caudal analgesia in infra-umbilical surgery significantly prolongs the duration of postoperative analgesia when compared to bupivacaine alone without any side-effects.

Abstract
Failed Tracheal Intubation with Subsequent inability to maintain an open airway and adequate oxygenation is the most frequent cause of brain damage or death during anesthesia. Recognizing before anesthesia the potential for difficult intubation allows time for optimal preparation. Proper Selection of equipment and techniques is needed to avoid unwanted situation. To find out difficulties associated with endotracheal intubation using Modified Mallampati Test (MMT) combined with Thyromental Height Test (TMHT) and MMT without TMHT. This prospective observational study was conducted at the Department of Anesthesia in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from April 2018 to September 2018. Two hundred two patients with different surgical procedures under general anaesthesia in different operation theaters of BSMMU, Dhaka were selected as study population. After taking written consents from each patient or his/her attendant elaborate history of illness, meticulous clinical examinations were performed and relevant laboratory investigations were done. All information was recorded in a preformed data sheet and statistical analysis was done by SPSS-22.0. Mean age ±SD of the study subjects was 42.49±14.29 years in MMT with TMHT group and 43.40±15.39 years in MMT without TMHT group. Females were enrolled more than males in both the groups. BMI was 28.75±3.59kg/m² in MMT with TMHT group and 29.44±8.64kg/m² in MMT without TMHT group. There were no significant differences in age, gender and BMI between the groups. Sensitivity, specificity, PPV, NPV and accuracy were 100.0%, 96.0%, 96.2%, 100.0% and 98.0% respectively of MMT with TMHT in predicting intubation difficulty. Sensitivity, specificity, PPV, NPV and accuracy were 100.0%, 96.0%, 96.2%, 100.0% and 98.0% respectively of MMT only in predicting intubation difficulty. MMT combined with TMHT is a better predictor of intubation difficulty than MMT alone.

Abstract
Introduction A medicinal plant, Myristica fragrans seed meal (nutmeg), was utilized to evaluate its impact on the growth, immunity, and antioxidant defense of zebrafish (Danio rerio). Methods In this regard, zebrafish (0.47 ± 0.04 g) (mean ± S.D.) were fed with 0% (control), 1% (T1-nutmeg), 2% (T2-nutmeg), and 3% (T3-nutmeg) of powdered nutmeg for 70 days. At the end of the feeding trial, growth performance, survival rate of fish, and temperature-challenge effects were recorded. Immune and antioxidant parameters were also assessed through the collection of serum and skin mucus samples. Results The results indicated that nutmeg supplementation did not significantly influence the growth of zebrafish (P > 0.05); however, the survival rate of fish fed with 2 and 3% of nutmeg supplementation significantly decreased (P < 0.05). The skin mucus and serum total protein, total immunoglobulin (Ig), and lysozyme activity were significantly increased in T3-nutmeg treatment in comparison to the control (P < 0.05). Superoxide dismutase (SOD) and catalase (CAT) activities were also enhanced in the T3-nutmeg group (P < 0.05). Nutmeg supplementation significantly upregulated the mRNA expression of growth hormone (gh) and insulin growth factor-1 (igf-1). Moreover, the nutmeg inclusion upregulated the expression of interleukin-1β (IL-1β), lysozyme, sod, and cat. The dietary supplementation of nutmeg significantly increased the resistance of zebrafish against cold-water shock and survivability afterward (P < 0.05). Discussion In conclusion, the supplementation of 3% powdered nutmeg in zebrafish diets could be suggested as an effective immune stimulator that improves antioxidant defense and stress tolerance.

Abstract
The isotropic to ferroelectric nematic liquid transition was theoretically studied over one hundred years ago, but its experimental studies are rare. Here we present experimental results and theoretical considerations of novel electromechanical effects of ferroelectric nematic liquid crystal droplets coexisting with the isotropic melt. We find that the droplets have flat pancake-like shapes that are thinner than the sample thickness as long as there is room to increase the lateral droplet size. In the center of the droplets a wing-shaped defect with low birefringence is present that moves perpendicular to a weak in-plane electric field, and then extends and splits in two at higher fields. Parallel to the defect motion and extension, the entire droplet drifts along the electric field with a speed that is independent of the size of the droplet and is proportional to the amplitude of the electric field. After the field is increased above 1 mV μm-1 the entire droplet gets deformed and oscillates with the field. These observations led us to determine the polarization field and revealed the presence of a pair of positive and negative bound electric charges due to divergences of polarization around the defect volume.

Abstract
The prevalence of diabetes mellitus is a significant global public health concern, particularly in emerging nations like Bangladesh. Bangladesh is already overrun with non-communicable diseases while still battling communicable diseases. About 90.0% of all cases of diabetes that have been diagnosed are type 2 diabetes. High calorie diet, age, sedentary lifestyle and obesity are the main risk factors for type 2 diabetes. Different micronutrients have been linked to an increased incidence of diabetes in addition to existing risk factors. The goal of the study was to assess the serum levels of calcium and magnesium in people with type 2 diabetes mellitus and compare them to those in healthy controls. This cross-sectional study was conducted from July 2018 to June 2019 at the Mymensingh Medical College, Mymensingh, Department of Biochemistry in cooperation with the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Purposive (non-random) sampling was used to pick the subjects based on inclusion and exclusion criteria. This study had 100 individuals in total. Out of them, 50 people with type 2 diabetes mellitus who had been diagnosed were chosen as cases, and another 50 people who appeared to be in generally good health were chosen as controls. Serum calcium and magnesium levels were measured for this study's analytical purposes. The mean±SD was used to express all values. The statistical package for social science (SPSS), a Windows application, was used to conduct the statistical analyses. Using the Student's unpaired 't' test, the statistical significance of the difference between the case and control groups was assessed. Following comprehensive analysis, it was discovered that type 2 diabetes mellitus patients had considerably lower mean serum calcium (in case group was 8.46±0.63 and control group 8.86±0.64mg/dl) and magnesium levels (in case group was 2.09±0.42 and control group 2.24±0.16mg/dl) than healthy controls. According to the results of the current investigation, patients with type 2 diabetes mellitus had significantly altered serum calcium and magnesium levels. As a result, the study's hypothesis was accepted.

Abstract
Food color additives are used to make food more appetizing. The United States Food and Drug Administration (FDA) permitted nine artificial colorings in foods, drugs, and cosmetics, whereas the European Union (EU) approved five artificial colors (E-104, 122, 124, 131, and 142) for food. However, these synthetic coloring materials raise various health hazards. The present review aimed to summarize the toxic effects of these coloring food additives on the brain, liver, kidney, lungs, urinary bladder, and thyroid gland. In this respect, we aimed to highlight the scientific evidence and the crucial need to assess potential health hazards of all colors used in food on human and nonhuman biota for better scrutiny. Blue 1 causes kidney tumor in mice, and there is evidence of death due to ingestion through a feeding tube. Blue 2 and Citrus Red 2 cause brain and urinary bladder tumors, respectively, whereas other coloring additives may cause different types of cancers and numerous adverse health effects. In light of this, this review focuses on the different possible adverse health effects caused by these food coloring additives, and possible ways to mitigate or avoid the damage they may cause. We hope that the data collected from in vitro or in vivo studies and from clinical investigations related to the possible health hazards of food color additives will be helpful to both researchers and the food industry in the future.

Abstract
Acute coronary syndrome is a growing public health concern. Diabetic patients are more vulnerable to develop acute coronary syndrome due to accelerated atherosclerosis. Acute coronary syndrome is common in diabetes mellitus and is a major cause of mortality and morbidity in these patients. Troponin-I is a biochemical marker for cardiac muscle injury. Elevated glycated hemoglobin (HbA1c) is also regarded as an independent risk factor for acute coronary syndrome in patients with diabetes mellitus.The aim of this study was to assess the relationship of HbA1c and Troponin-I level in patients with acute coronary syndrome. This cross-sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh from July 2018 to June 2019. Total study subjects were ninety five of both gender selected from the admitted patients of the cardiology department of the National Institute of Cardiovascular Diseases (NICVD), Dhaka. Diagnosis of acute coronary syndrome was confirmed by cardiologist. Diagnosis of diabetes mellitus was confirmed by Random Blood Glucose (RBG) level. Study subjects were grouped, acute coronary syndrome with diabetes mellitus as Group A and acute coronary syndrome without diabetes mellitus as Group B. Baseline parameters was recorded in data collection sheet. HbA1c, Troponin-I level of all study subjects were analyzed and recorded. Mean age of the study subjects in Group A and Group B were 51.06 years and 51.66 years respectively. Male gender was predominant in both groups. Mean SBP and DBP were significantly higher in Group A than Group B. Mean HbA1c level of the study subjects in Group A was significantly higher than Group B (p=0.001). Mean Troponin-I level in Group A was also significantly higher than Group B (p=0.023). HbA1c and Troponin-I levels were positively correlated in Group A (r=0.471, p=0.001). The present study demonstrated significant positive correlation of HbA1c and Troponin-I level in diabetic patients with acute coronary syndrome.

Abstract
Acute myocardial infarction (AMI) in younger adults (≤40 years) is being increasingly encountered in recent years among the South Asian population. Data regarding the presentation, risk factors and angiographic findings on this important subset of patients is lacking in our country. The aim of this study was to compare the risk factors and pattern of Coronary artery involvement in younger patients presenting with AMI with that of the older age group. This was a cross-sectional observational study conducted during the period from October 2018 to June 2019. Seventy consecutive AMI patients age ≤40 years and another 70 consecutive AMI patients age >40 years undergoing Coronary Angiogram (CAG) were included in the study. After taking informed written consent; demographic, anthropometric, risk factors, CAG findings were recorded in a pre-designed case record form. The severity of Coronary Artery Disease (CAD) was calculated by using Gensini score. The mean age of the younger and older patient groups was 36.89±4.4 years and 57.00±8.4 years respectively. Among the risk factors, smoking (67.1% versus 45.7%, p=0.017), positive family history CAD (38.6% versus 22.9%, p=0.040) and obesity (34.3% versus 20.0%, p= 0.05) were more common in younger group. Whereas, Hypertension (41.4% versus 72.9%, p=0.010) and DM (28.6% versus 50.0%, p=0.024) were more common in older patients. Younger patients mainly presented with STEMI (60.0% versus 48.6%) and predominantly had single vessel disease (42.9%), whereas older patients readily presented with NSTEMI (51.4%) and had a higher incidence of double vessel disease (32.9%) and triple vessel disease (30.0%). The Median Gensini score was significantly higher among the older patients than in the younger age group. Patients in younger age group showed a different pattern of risk factors and coronary artery involvement in comparison to the older age group. Thus, offering younger individuals to make them aware of these risk factors and their early detection, as well as an effective intervention may help to prevent AMI in younger people.

Abstract
Acute myocardial infarction (AMI) commonly known as heart attack is defined pathologically as the irreversible death of myocardial cells caused by ischemia. Risk factors include high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol and excessive alcohol intake. The major cause of acute MI is coronary atherosclerosis with superimposed luminal thrombus, which accounts for more than 80% of all infarcts. Micronutrients and trace elements are very essential for normal functioning of the body. Even though they are required in very small amount, an alteration in the level of this element may lead to serious diseases like CAD and its consequences. The injury induced by reperfusion of the ischemic myocardium could result partially from the cytotoxic effects of oxygen free radicals. Copper is involved in several of the reactions in the protection from free radical damage. So, this study was designed to evaluate serum cupper level in AMI patients. This case-control study was conducted in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh from July 2016 to June 2017. Total number of subjects was 120 in number. Among them 60 were diagnosed case of acute myocardial infarction and 60 were apparently healthy volunteers. Data were collected using pre-designed data collection sheets. After proper counseling informed written consent was taken from the study population. The study revealed that mean serum copper level was higher in case group as compared to control group. The mean±SD values of copper were 105.44±24.15μg/dl and 146.49±23.52μg/dl in control and case group respectively. The level of significance was 0.001 (p<0.05). After analyzing the results of the study it is concluded that serum copper level was significantly higher in Acute Myocardial Infarction patients than normal individuals. Therefore, estimation of serum copper level in AMI patients might be useful to take appropriate measure to prevent free radical induced reperfusion injury.

Abstract
Plant seeds are the resources of many different bioactive components. The chemical composition of the different crude extracts from Benincasa hispida (White pumpkin) and Cucurbita moschata (Pumpkin) seeds with three different polarity-based solvents (n-hexane, n-hexane-chloroform (2:1), and methanol) was analyzed to identify the biologically active compounds. Each of the extracts was analyzed by gas chromatography-mass spectrometry. Different extracts of targeted seeds showed different biologically active compounds that have different pharmacological potentialities. 9, 12-Octadecadienoic acid (ZZ) was the most potent bioactive compound present in three different extracts of both B. hispida and C. moschata. Another bioactive compound comparatively low percentage present in both plants was n-hexadecanoic acid. Other major pharmacologically active compounds present in both plants were 9- Octadecenoic acid (Z)-, methyl ester, and 9, 12-Octadecadienoic acid methyl ester (E, E). Besides these compounds, a few more biologically active compounds were present in the two plants separately. The findings of this study support the use of these seeds in modern functional foods, nutraceuticals, and medicinal purposes, and the whole seeds would give better health benefits rather than use any extract. Although further pharmacological examinations should be carried out to conclude the medicinal application of the seeds of these two plants as well as to understand the mechanism of the potential health benefits.

Abstract
The objective of study was to evaluate the clinical outcome of topical 0.2% Glyceryl trinitrate topical (GTN) ointment in the treatment of chronic anal fissure. This randomized control trial was carried out in the Colorectal Surgery Unit, Department of Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from May 2015 to April 2016. Total 94 patients were included in this trial, where 47(50.0%) patients were treated by 0.2% GTN ointment as Trial group 12 hourly for 8 weeks and 47(50.0%) patients by lateral internal sphincterotomy (LIS) as Control group in this study. Patients were randomized in two groups by lottery following purposive sampling. Post-procedural outcome variables with 6 months follow up were evaluated. Majority of the patients were found in between 20 to 40 years of age in both groups. The mean age was 34.6±10.4 years and 33.2±8.6 years in GTN and LIS respectively. Overall male female ratio was 0.88:1. All (100.0%) patients presented with pain in anus and 86.15% patients presented with per rectal bleeding. Pain relief in GTN arm versus LIS arm in 2nd and 6th week was 55.31% vs. 76.6%, 74.5% vs. 87.23% with no significant difference between two groups. But at 6 month it was 57.44% vs. 93.6% respectively. The fall in pain relief at 6th month in GTN arm was due to recurrence of fissure. At the end of 2nd, 6th week and 6month, cessation of bleeding improved gradually in both groups after treatment but the improvement was significantly better in LIS group than in GTN group indicating sphincterotomy stops bleeding better. Healing after 2nd week in both groups was minimum but equal 2(4.26%) patients. After 6 weeks LIS group had significant better healing than GTN 40(85.1%) versus 26(55.3%) with p value <0.001. In 6 month time GTN group had increased healing but LIS group had significant better healing than GTN group 42(89.36) vs. 32(68.08) with p value 0.004. Transient flatus and liquid incontinence were 8.51% and 6.4% respectively in LIS group with 0.0% in GTN group. Headache and recurrence were significantly higher in GTN group 61.7% and 34.04% with p<0.001. Lateral internal anal sphincterotomy is superior to the topical application of 0.2% nitroglycerin ointment in the treatment of chronic anal fissure with the advantages of good symptomatic relief, high rate of healing and a very low rate of transient continence disturbances.

Abstract
Thalassemia is the most prevalent single gene defect in human beings worldwide. Repeated blood transfusions along with chelation therapy are mainstay of treatment in thalassemia patients. However these recurrent blood transfusions result in iron overload which along with chelation therapy causes deterioration of liver function. Aim of the study was to evaluate the liver function tests in β-thalassemia major patients. This cross sectional study was conducted in the Department of Biochemistry, Dhaka Medical College, Dhaka, Bangladesh from January 2017 to December 2017. In this study, 50 diagnosed patients of β Thalassemia major (Group A) and 50 apparently healthy children (Group B) of both sexes were selected from the department of Paediatrics, Dhaka medical college. The study parameters were serum ferritin, bilirubin, AST, ALT, ALP. The results were compared statistically between groups. Serum ferritin level (mean±SD) in thalassemic major patients in Group A (890±446.38 microgram/L) which is significantly higher above normal level. Serum bilirubin in Group A (3.27±2.62 mg/dl) and in Group B (0.48±0.24 mg/dl), Serum ALT in Group A (53.06±34.0 U/L) and in Group B (16.70±4.81 U/L), AST in Group A (84.56±33.54 U/L) and in Group B (11.60±2.72 U/L) and ALP levels in Group A (422.42±226.99 IU/L) and in Group B (221.86±80.54 IU/L). All the values were significantly higher (p<0.001) in β-thalassemia patient than that of normal children. This study concludes that liver function parameters are significantly higher in β thalassemia major patients. So routine evaluation of liver function tests may be advocated for thalassemic patients to predict early onset of hepatic dysfunction.

Abstract
To compare the outcome of the laparoscopic totally extra peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia. This study was conducted as a prospective comparative (Quasi experimental) study from January 2010 to December 2010 at Combined Military Hospital (CMH), Dhaka, Bangladesh. A total of 100 male patients aged 24 to 70 years who underwent laparoscopic totally extra-peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia were included in this study. Data of operating time, intraoperative and short-term postoperative complications, postoperative pain, postoperative hospital stay and return to normal activity were recorded and analyzed with SPSS program. Mean age of the patients was 51.39±15.099 years in OLMR group (Group A) and 47.10±9.338 years in Lap TEP group (Group B). Mean operating time was longer in Laparoscopic TEP group (Group B, 57.67±6.915 minutes) then open Lichtenstein mesh repair group (Group A, 50.56±6.292 minutes). Patient in the Lap TEP group (Group B) experienced less post operative pain, less post operative complications, shorter hospital stay and early return to normal activity then OLMR group (Group A). One patient (3.33%) in group B needed conversion to open Lichtenstein method. Two (6.66%) patients developed pneumoperitoneum in Group B (Lap TEP repair). Superficial wound infection developed in five (7.14%) patients in OLMR group (Group A) and two (6.66%) patients in Lap TEP group (Group B). In Laparoscopic TEP group (Group B) and Lichtenstein group (Group A), patients return to normal activity within on an average 07 and 11 days respectively. Laparoscopic totally extra peritoneal (TEP) mesh repair technique was associated with less post operative pain, less post operative complications, shorter hospital stay, faster recovery with early return to normal activity compared with Lichtenstein tension free mesh repair of inguinal hernia.

Abstract
Background and Aims The ongoing public health emergency has created incredible fear of getting the infection and a terrible psychological burden among all levels. The pandemic has severely affected private job holders' economic status and lifestyle factors in Bangladesh. Here we aimed to assess fear and depressive symptoms among private job holders in Bangladesh during the Covid‐19 pandemic and associated risk factors. Methods We conducted this online cross‐sectional survey between January 15, 2021, and March 15, 2021, among 510 private job holders aged above 18 years. We followed the convenience sampling method for data collection. We assessed sociodemographic factors and two psychometric parameters. We applied the Fear of Covid‐19 Scale and Patient Health Questionnaire‐9 to assess increased fear and depressive symptoms, respectively. Chi‐square test, independent sample t‐test, and binary logistic regression analysis were performed for data analysis. Results The prevalence of increased fear and depressive symptoms were 86.27% and 42.16%, respectively. Factors associated with increased fear among private job holders during COVID‐19 were economic class, obesity, on‐time salary, company's downsizing policy, salary reduction, home office, and transportation facilities. However, depressive symptoms were associated with marital status, education level, residence area, the organizational practice of health safety rules, company performance, on‐time salary, health insurance, downsizing, salary reduction policy, organization type, transportation, and mental health support at work. The present study also noticed some interrelations among the above factors with mental health issues. Conclusion Based on the present findings, we recommend actionable items to improve the mental health of private job holders in Bangladesh due to the ongoing pandemic. Authorities can develop mental health support programs and efficient Covid‐19 response systems. The policymakers and regulatory bodies might take some initiatives to promote mental health in the private sector in Bangladesh.

Abstract
In this research we collect, prepare and analyze a geospatial database of maritime activities located in the northern Bay of Bengal with the final aim to simulate maritime spatial planning (MSP) - ready information source for future sectoral and multi-sector MSP in Bangladesh. The database is composed of 28 anthropogenic and environmental layers categorized into seven Blue Economy sectors. The database is analyzed with a set of geospatial models aimed at understanding the intensity distribution of human activities at sea and the potential marine use conflicts emerging from the aggregation of human activities. Ecological resources were characterized in terms of marine mammals, lobsters, commercially important and threatened fish species, and pelagic birds and mapped as biodiversity hotspots using geographic cluster analysis. Results show that the most intensely used sea areas are located along the northeastern coast of Bangladesh, as well as in the Swatch of No Ground (SoNG) area, with maximum Marine Use Intensity (MUI) scores ranging from 5 to 8. Offshore waters of Saint Martin's Island have higher MUI scores (≥ 5) as well. The pairwise spatial conflict analysis shows that nature protection sites particularly SoNG Marine Protected Area (MPA), Nijhum Dwip Marine Reserve (MR), and Saint Martin's Island MPA are exposed to the high Marine Use Conflicts (MUC) induced by fishing and shipping activities. Fishing operations generate the highest MUC value (MUC = 30) in SoNG MPA, whereas shipping activities produce the highest MUC value (MUC = 24) in Nijhum Dwip MR. Both of the MPAs exhibit 6 to 12 MUC scores induced by shipping. The proposed database together with the illustrated analytical techniques used in this study and key findings can provide the first understanding of the priorities for Ecosystem Based Management of Bangladesh's marine space and provide valuable insights on the urgency for MSP process in the country. The study concludes with an outlook on the utility of the database for future analysis.

Abstract
The role of uric acid as a risk factor for cerebrovascular disease, particularly acute ischemic stroke, is controversial and there is little information about this in our setting. This cross-sectional study was conducted at the departments of Medicine and Neurology of a tertiary hospital in Bangladesh over one year, from January 2018 to December 2018, to estimate serum uric acid (SUA) levels and assess its risk factor potential in patients with acute ischemic stroke. Forty-five patients with acute ischemic stroke were enrolled and a similar number of age and sex-matched healthy individuals were recruited for comparison. All known risk factors for stroke were searched and SUA levels were measured. SUA was higher (6.66±2.33 vs. 5.23±1.81 mg/dL; p=0.002) and hyperuricemia was more frequent (64.4% vs. 24.4%, p<0.001) in stroke patients in comparison to the controls. Hypertension was more frequent among stroke patients. In multivariate analysis, hyperuricemia [OR 4.51 (95% CI 1.67-12.16; p<0.05)] and HTN [OR 6.31 (95% CI 2.26-17.61; p<0.001)] were found to be independent risk factors of acute ischemic stroke. The stroke and control groups had no differences in age, sex, residence, education, monthly income, occupation, fasting plasma glucose, triglyceride and high-density lipoprotein cholesterol levels. Total cholesterol and low-density lipoprotein cholesterol levels were higher in the stroke patients. SUA may be used as a marker for increased risk of ischemic stroke. However, larger-scale studies are needed to get more insight into our findings.

Abstract
Coronavirus Disease (COVID-19), which began as a small outbreak in Wuhan, China, in December 2019, became a global pandemic within months due to its high transmissibility. In the absence of pharmaceutical treatment, various non-pharmaceutical interventions (NPIs) to contain the spread of COVID-19 brought the entire world to a halt. After almost a year of seemingly returning to normalcy with the world's quickest vaccine development, the emergence of more infectious and vaccine resistant coronavirus variants is bringing the situation back to where it was a year ago. In the light of this new situation, we conducted a study to portray the possible scenarios based on the three key factors: impact of interventions (pharmaceutical and NPIs), vaccination rate, and vaccine efficacy. In our study, we assessed two of the most crucial factors, transmissibility and vaccination rate, in order to reduce the spreading of COVID-19 in a simple but effective manner. In order to incorporate the time-varying mutational landscape of COVID-19 variants, we estimated a weighted transmissibility composed of the proportion of existing strains that naturally vary over time. Additionally, we consider time varying vaccination rates based on the number of daily new cases. Our method for calculating the vaccination rate from past active cases is an effective approach in forecasting probable future scenarios as it actively tracks people's attitudes toward immunization as active case changes. Our simulations show that if a large number of individuals cannot be vaccinated by ensuring high efficacy in a short period of time, adopting NPIs is the best approach to manage disease transmission with the emergence of new vaccine breakthrough and more infectious variants.

Abstract
Alternative sources of fish oil (FO) are one of the major problems in aquaculture; therefore, the goal of the present study was to examine insect (black soldier fly larvae) oil (BSLO) as a potential replacer of fish/soy oil in juvenile rainbow trout (initial average weight of 32 ± 0.15 g) feed. Four diets were formulated wherein FO (control diet) was completely replaced with either soybean oil (SO) or BSLO, and an additional BSLO-based diet supplemented with 1.5% bile acid (BSLO + BA) were fed to the fish for 10 weeks. Growth performance of the BSLO fed group was similar (P > 0.05) to that of the FO and SO fed groups, however, the fish fed BSLO + BA diet registered the lowest growth (P < 0.05). Oil sources did not (P > 0.05) affect the major nutrient content of whole-body, however, the fatty acid composition of the muscle and liver was influenced (P < 0.05), with the highest 14:0, 16:0, and total saturated fatty acid detected in BSLO or BSLO + BA fed trout compared to the others (P < 0.001). No significant differences were observed in eicosapentaenoic acid + docosahexaenoic acid (EPA + DHA) or total n-3 polyunsaturated fatty acid (PUFA) content in muscle among the groups, whereas, the highest EPA:DHA and n-3:n-6 ratios were detected in the FO group. Gene expression for fatty acid binding protein (fabp), fatty acid synthase (fas), and Δ5 desaturase in the liver was lower in FO (P < 0.05), while BSLO + BA registered the highest Δ6 expression (P = 0.006). Supplementation of BA in the BSLO diet increased superoxide dismutase (SOD) and catalase (CAT) activities compared to the other groups (P < 0.05). In conclusion, BSLO could serve as a substitute for FO and SO in rainbow trout diet without negatively impacting growth performance, whole-body composition and nutrient retention, and modulate the expression of fatty acid metabolism-related genes in rainbow trout.

Abstract
With reduced prevalence of visceral leishmaniasis (VL) in the Indian subcontinent (ISC), direct and field deployable diagnostic tests are needed to implement an effective diagnostic and surveillance algorithm for post-elimination VL control. In this regard, here we investigated the diagnostic efficacies of a loop-mediated isothermal amplification (LAMP) assay (Loopamp™ Leishmania Detection Kit, Eiken Chemical CO., Ltd, Japan), a real-time quantitative PCR assay (qPCR) and the Leishmania antigen ELISA (CLIN-TECH, UK) with different sampling techniques and evaluated their prospect to incorporate into post-elimination VL control strategies. Eighty clinically and rK39 rapid diagnostic test confirmed VL cases and 80 endemic healthy controls were enrolled in the study. Peripheral blood and dried blood spots (DBS) were collected from all the participants at the time of diagnosis. DNA was extracted from whole blood (WB) and DBS via silica columns (QIAGEN) and boil & spin (B&S) methods and tested with qPCR and Loopamp. Urine was collected from all participants at the time of diagnosis and was directly subjected to the Leishmania antigen ELISA. 41 patients were followed up and urine samples were collected at day 30 and day 180 after treatment and ELISA was performed. The sensitivities of the Loopamp-WB(B&S) and Loopamp-WB(QIA) were 96.2% (95% CI 89·43-99·22) and 95% (95% CI 87·69-98·62) respectively. The sensitivity of Loopamp-DBS(QIA) was 85% (95% CI 75·26- 92·00). The sensitivities of the qPCR-WB(QIA) and qPCR-DBS(QIA) were 93.8% (95% CI 86·01-97·94) and 72.5% (95% CI 61·38-81·90) respectively. The specificity of all molecular assays was 100%. The sensitivity and specificity of the Leishmania antigen ELISA were 97.5% (95% CI 91·47-99·70) and 91.95% (95% CI 84·12-96·70) respectively. The Leishmania antigen ELISA depicted clinical cure at day 180 in all the followed-up cases. Efficacy and sustainability identify the Loopamp-WB(B&S) and the Leishmania antigen ELISA as promising and minimally invasive VL diagnostic tools to support VL diagnostic and surveillance activities respectively in the post-elimination era.

Abstract
Abstract
The increasing demand for energy in Bangladesh as well as all over the world is continuously growing unabated because of the increase of the world population and the countries’ fast-developing industrialization programs. In this critical stage of energy crisis, renewable energy is a highly welcome reliable energy source wherein wind energy is the cheapest replenishable and available energy source of the time. Regarding this particular energy source, a feasibility study of the wind energy in Chittagong has been done by analyzing the wind speed data. It is estimated that the maximum practical power output generated can be 124.53 MW at Parky beach. The number of wind turbines, operation and maintenance cost and pay-back period of those sites are also calculated.

Abstract
BACKGROUND Asymptomatic Leishmania infections outnumber clinical infections on the Indian subcontinent (ISC), where disease reservoirs are anthroponotic. Diagnostics which detect active asymptomatic infection, which are suitable for monitoring and surveillance, may be of benefit to the visceral leishmaniasis (VL) elimination campaign on the ISC. METHODS Quantitative polymerase chain reaction (qPCR), loop-mediated isothermal amplification (LAMP), and the direct agglutination test (DAT) were carried out on blood samples, and the Leishmania antigen ELISA was carried out on urine samples collected from 720 household and neighbouring contacts of 276 VL and post-kala-azar dermal leishmaniasis (PKDL) index cases, with no symptoms or history of VL or PKDL, in endemic regions of Bangladesh between September 2016 and March 2018. RESULTS Of the 720 contacts of index cases, asymptomatic infection was detected in 69 (9.6%) participants by a combination of qPCR (1.0%), LAMP (2.1%), DAT (3.9%), and Leishmania antigen ELISA (3.3%). Only one (0.1%) participant was detected positive by all four diagnostic tests. Poor agreement between tests was calculated using Cohen's kappa (κ) statistics; however, the Leishmania antigen ELISA and DAT in combination captured all participants as positive by more than one test. We find evidence for a moderately strong association between the index case being a PKDL case (OR 1.94, p = 0.009), specifically macular PKDL (OR 2.12, p = 0.004), and being positive for at least one of the four tests. CONCLUSIONS Leishmania antigen ELISA on urine detects active asymptomatic infection, requires a non-invasive sample, and therefore may be of benefit for monitoring transmission and surveillance in an elimination setting in combination with serology. Development of an antigen detection test in a rapid diagnostic test (RDT) format would be of benefit to the elimination campaign.

Abstract
Black solider fly larvae (BSFL) and their oils (BSFLO) are receiving increasing attention as sustainable ingredients in fish feeds, but mostly as replacements to marine sources. There were two aims to this study; in exp. 1, soybean meal (SBM)-based diets were formulated to contain BSFL as supplements at 0 (SBM), 8 (SBM + BSFLlow) or 16% (SBM + BSFLhigh) with a control diet being fishmeal-based (FM). In exp. 2, diets included only fish oil (FO), soybean oil (SBO), BSFLO or BSFLO + bile acid (BA), and all lipid sources were added at 16%. Both experiments were run at the same time and fed to rainbow trout (32 g) with each treatment being triplicated. After 10 weeks the fish were sampled for liver and distal intestine histology, expression of genes responsible for inflammation in the intestine and kidneys, and serum peroxidase and lysozyme activities. In exp. 1, supplementations of BSFL effectively prevented SBM-induced intestinal enteritis, down-regulated intestinal prostaglandin and interferon regulatory factor 1 (IRF-1), while the SBM + BSFLhigh diet significantly increased serum lysozyme activity. In exp. 2, BSFLO caused no histomorphological change to the liver or intestine, but kidney interluekin-8, tumor necrosis factor and IRF-1 were significantly upregulated along with significantly higher serum peroxidase activity. The inclusion of BA in the BSFLO diets significantly upregulated intestinal prostaglandin gene expression. Overall, BSFL supplementations of 8 or 16% prevented SBM-induced intestinal enteritis based on histological observations, which was supported by a down-regulation in pro-inflammatory genes and enhanced innate immunity. Meanwhile, the use of BSFLO showed some immunological benefits. Therefore, these sustainable resources are recommended in the diets of rainbow trout, especially when using elevated levels of plant-based proteins.

Abstract
What are the ground states of an interacting, low-density electron system? In the absence of disorder, it has long been expected that as the electron density is lowered, the exchange energy gained by aligning the electron spins should exceed the enhancement in the kinetic (Fermi) energy, leading to a (Bloch) ferromagnetic transition. At even lower densities, another transition to a (Wigner) solid, an ordered array of electrons, should occur. Experimental access to these regimes, however, has been limited because of the absence of a material platform that supports an electron system with very high quality (low disorder) and low density simultaneously. Here we explore the ground states of interacting electrons in an exceptionally clean, two-dimensional electron system confined to a modulation-doped AlAs quantum well. The large electron effective mass in this system allows us to reach very large values of the interaction parameter [Formula: see text], defined as the ratio of the Coulomb to Fermi energies. As we lower the electron density via gate bias, we find a sequence of phases, qualitatively consistent with the above scenario: a paramagnetic phase at large densities, a spontaneous transition to a ferromagnetic state when [Formula: see text] surpasses 35, and then a phase with strongly nonlinear current-voltage characteristics, suggestive of a pinned Wigner solid, when [Formula: see text] exceeds [Formula: see text] However, our sample makes a transition to an insulating state at [Formula: see text], preceding the onset of the spontaneous ferromagnetism, implying that besides interaction, the role of disorder must also be taken into account in understanding the different phases of a realistic dilute electron system.

Abstract
Researchers have found many similarities between the 2003 severe acute respiratory syndrome (SARS) virus and SARS-CoV-19 through existing data that reveal the SARS's cause. Artificial intelligence (AI) learning models can be created to predict drug structures that can be used to treat COVID-19. Despite the effectively demonstrated repurposed drugs, more repurposed drugs should be recognized. Furthermore, technological advancements have been helpful in the battle against COVID-19. Machine intelligence technology can support this procedure by rapidly determining adequate and effective drugs against COVID-19 and by overcoming any barrier between a large number of repurposed drugs, laboratory/clinical testing, and final drug authorization. This paper reviews the proposed vaccines and medicines for SARS-CoV-2 and the current application of AI in drug repurposing for COVID-19 treatment.

Abstract
We evaluated the efficacy of mozuku fucoidan supplementation to alternative dietary proteins used in fish meal (FM) replacement to enhance growth, immunity, and stress resistance of Pagrus major. Seven isonitrogenous (45% protein) experimental diets were formulated where diet 1 (D1) was FM-based control diet. Diets 2 to 7 were formulated by replacing 25, 50, and 75% of FM protein with soy protein isolate (SPI) protein, and each replacement level was supplemented without or with fucoidan at 0.4% for diet groups D2 (FM25), D3 (FM25Fu), D4 (FM50), D5 (FM50Fu), D6 (FM75), and D7(FM75Fu), respectively. Each diet was randomly allocated to triplicate groups of fish (4.1 g) for 56 days. Significantly higher weight gain and specific growth rate were observed in fish fed FM50Fu diet group, and it was not differed (P > 0.05) with fish fed FM25Fu diet group. FM-based control diet showed intermediate value, and it was not differed (P > 0.05) with or without fucoidan-supplemented ≤ 50% FM replacement groups and FM75Fu diet group. Significantly lower growth performances were observed in FM75 diet group. At each replacement level, fucoidan-supplemented groups showed nonsignificant improvement of feed utilization performances. Fish fed fucoidan-supplemented diets showed best condition of oxidative and freshwater stress resistance. Lysozyme activity, NBT, and peroxidase activity showed higher (P > 0.05) values in fucoidan-supplemented groups compared with the non-supplemented groups. Catalase activity was significantly lower in FM75Fu diet group. Catalase activity is significantly influenced by the interaction effects of fucoidan and FM replacement level. In conclusion, fucoidan supplementation could increase the efficiency of utilizing SPI (≥ 75%) without any adverse effects on red sea bream performance.

Abstract
Acute myocardial infarction has many risk factors and etiologies. Different factors are responsible for adverse in-hospital outcome after acute MI. Status of plasma vitamin D level has been found to be a good predictor of future adverse cardiovascular outcomes in patients with acute MI. Plasma vitamin D level has been considered as a potential marker for identifying individuals under risk of CAD and associated events. This study was done to investigate the role of plasma vitamin D level in predicting in-hospital adverse cardiac events in patients with acute MI. This cross sectional descriptive type of study was conducted in the cardiology department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from October 2017 to March 2019. Total 257 patients of first attack of acute MI were included considering inclusion and exclusion criteria. Fasting blood samples were analyzed for plasma vitamin D level. Sample population were grouped at first into two, normal and low vitamin D level, taking 30ng/ml as cut-off value, low vitamin D level is further subdivided into insufficiency (21-29ng/ml), deficiency (10-20ng/ml) and severe deficiency (<10ng/ml). Adverse in-hospital cardiac outcomes were observed. In-hospital adverse outcomes occurred in 42.9% patients having normal vitamin D level (>30ng/ml), 66.2% of patients having vitamin D insufficiency (21-29ng/ml), 78.2% of patients having vitamin D deficiency (10-20ng/ml) and 94.4% patients having severe vitamin D deficiency (<10ng/ml), which was statistically significant (p<0.05). Heart failure (30.3%, 47.7%, 63.6% and 77.8%, p<0.05), cardiogenic shock (12.6%, 27.7%, 34.5% and 33.3%, p<0.05), Arrhythmias (14.3%, 21.5%, 23.6% and 22.2%, p>0.05), death (2.5%, 0%, 3.6% and 11.1%, p>0.05) occurred more in low vitamin D groups. Mean vitamin D level was significantly different between Group I and Group II (42.59±10.08 vs. 18.64±6.54, p<0.0001). Multivariate regression analysis showed vitamin D is an independent predictor of in-hospital adverse cardiac events (p=0.001). Age (p=0.001) and obesity (p=0.048) were also other predictors of in-hospital adverse cardiac events. Low plasma vitamin D level is an important predictor for in-hospital adverse cardiac events in patients hospitalized with first attack of acute MI.

Abstract
It has been widely reported that vitamin D deficiency is associated with Coronary heart disease (CHD), especially acute Myocardial infarction (MI). Many factors are responsible for reduced Left ventricular ejection fraction (LVEF) and acute Left ventricular fraction (LVF) after acute MI. This cross sectional descriptive type of study was conducted in the Cardiology department of Mymensingh Medical College Hospital from October 2017 to March 2019 to investigate the relationship of plasma vitamin D with LVEF in patients with first attack of acute MI. Total 185 patients of first attack of acute MI were included considering inclusion and exclusion criteria. Fasting blood samples were analyzed for plasma vitamin D level. Sample population were grouped at first into two, normal and low vitamin D level, taking 30ng/ml as cut-off value, low vitamin D level is further subdivided into insufficiency (21-29ng/ml), deficiency (10-20ng/ml) and severe deficiency (<10ng/ml). LVEF among the patients was observed. LVEF was found 49.88±8.58% patients having normal vitamin D level (>30ng/ml), 47.60±8.24% of patients having vitamin D insufficiency (21-29ng/ml), 44.38±8.12% of patients having vitamin D deficiency (10-20ng/ml) and 40.61±8.64% patients having severe vitamin D deficiency (<10ng/ml), which was statistically significant (p<0.05). So, low plasma vitamin D level is associated with reduced LVEF in patients hospitalized with first attack of acute MI.

Abstract
Anterior resection (AR), especially low anterior resection (LAR), for low rectal cancer and colorectal anastomosis is a technical challenge to surgeons. But by using circular stapling devices now it is possible make more LARs technically feasible. A stapled end-to-end colorectal anastomosis is increasingly adopted following a low anterior resection for low rectal cancer. This descriptive cross-sectional study was carried out in the department of Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. The ensuing doughnuts created from the stapling device are routinely sent for histological analysis. However, its efficacy remains debatable. This study aims to determine the role of sending distal doughnut for histological examination following a stapled end-to-end colorectal anastomosis done in low anterior resection for low rectal cancers.

Abstract
Among nurses due to inadequate pain management knowledge and practice skills, children's pain is often under treated. This study aimed to examine the level of knowledge and practice on pediatric pain management among nurses in Bangladesh. This was a descriptive survey study involving total 150 clinical pediatric nurses from two Medical College Hospital and a University hospital in Bangladesh. The data collection tool consisted of demographic data form, 32-items nurses' knowledge. There were 32 true and false questions related to nurses' knowledge on pediatric pain management in Bangladesh. The response formats to each item for correct answer was 1 and incorrect answer 0. The total scores were categorized into three levels including low (0-20), moderate (21-23) and high (24 and above). The data collection tool consisted of demographic data form, 19-item practice related questionnaire on pediatric pain management. Nurses' practice on pediatric pain management contained 19 items with 5-points Likert's scale ranging from 1=Never practice to 5=constantly practice. For each item, a score of 5 was accorded for constantly and 1 for never. The score ranged from 19-95. The total scores were categorized into three levels including low (19-38), moderate (39-76) and high (77-95). The results demonstrated that most of the nurses' knowledge score on pediatric pain management was at moderate level (mean=21.50, SD=2.35). Nurses' practice on pediatric pain management was also at moderate level (mean=75.45, SD=8.24). The relationship between nurses' knowledge and practice was not significant. In addition, nurses' knowledge and practice with demographic variables; there was significant relationship between nurse's knowledge and existence of pain management protocol, nurses' practice and their current position in unit and with reading nursing journal. This study showed moderate level of knowledge and practice indicating that they need to be enhanced the knowledge and practice skills in pediatric pain management.

Abstract
Bianchi squire first described scrotal incision orchiopexy as an alternative to the traditional approach in the1980s. In maximum premature and some mature infants, palpable testis is a common surgical problem. There are several surgical technique applied to overcome this surgical problems like combined inguinal and scrotal incision or single high transverse scrotal incision. The goal of this study assessed single high transverse scrotal incision for the management of PUT as regards to evaluate operative time, postoperative success and final cosmetic results. One hundred twenty patients were managed at the Paediatric Surgery Department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh with PUT during the period from 2015 to March 2018. We operated all cases between 6 to 12 months and excluded more than 12 months of age and recurrent cases. This technique involves manipulation of the testis down to the scrotum so that it is secured between the thumb and index finger as a fixation is performed. After fixation of testis high transverse scrotal incision was given, all layers were separated. Then enter into inguinal cannel by cutting of external ring. After dissecting the testis come down through the incision. After making dartos pouch through the same incision and orchidopexy done. All infants were followed-up at 1 month, 2 months and 6 months to detect operative times as well as position, testicular atrophy and the final cosmetic appearance. Patient age ranged from 6 months to 12 months. A total of 120 PUTs were operated upon in 100 patients. PUT was bilateral in 15 patients, right-sided in 55 cases and left-sided in 30 cases. Among 120 testes 40 testes were located distal to external inguinal ring (EIR), 70 testes were at internal inguinal ring (IIR) and 10 testes were in between EIR and IIR. A total of 100 patients were successfully placed within scrotum using a single incision. Operative time ranged from 20-36 minutes. There were no cases of testicular atrophy or ascent. The only complications were 3 wound infections (3%), which were successfully treated with antibiotics. Single high transverse scrotal incision was sufficient to deal with PUT especially, in young infants (age 6 months). The procedure results in shorter operative times, similar success and complication rates, and a more cosmetically appealing outcome compared to inguinal orchiopexy.

Abstract
Infections due to hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV) and hepatitis E (HEV) viruses are the major causes of hepatitis and are associated with significant morbidity and mortality in developing countries like Bangladesh. The aim of this study was to assess the distribution pattern of serological markers in patients of acute viral hepatitis. This was a hospital based observational cross sectional study among purposively selected 107 patients admitted with acute viral hepatitis in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from April 2017 to September 2017. Data were collected by face-to-face interview of the patients, clinical assessment and investigations of biochemical and serological parameters using a structured questionnaire. Descriptive analysis was done using the analytic software SPSS version 21.0. The mean age of the patients was 33.35±12.97 years. Majority was male (68.2%), Muslim (87.9%), married (72.9%) and came from urban area (63.6%) with different level of educational qualifications. The prevalence of viral hepatitis is higher in male (68.22%) than female (31.78%). The common clinical presentations were dark coloured urine (100.0%), yellow colouration of the sclera (100.0%), anorexia (90.6%), nausea/vomiting (79.4%) and abdominal pain (68.2%). Of the 107 patients, 51.40% (n=55) had acute viral E hepatitis, 36.40% (n=39) had acute viral B hepatitis, 12.15% (n=13) had acute viral A hepatitis. Mixed infection with both hepatitis E and A viruses was 1.87% (n=2). HEV and HBV are common in relatively older age while HAV is common in relatively younger age to cause acute viral hepatitis. The study revealed a high prevalence of HEV followed by HBV and HAV in the Bangladeshi population suspected of having suffered from acute viral hepatitis.

Abstract
We assessed the effects of fishmeal (FM) replacement by soy protein concentrate (SPC) with inosine monophosphate (IMP) supplementation on growth, digestibility, immunity, blood health, and stress resistance of red sea bream, Pagrus major. FM protein of a FM-based control diet (FM100) was replaced with 25 (FM75), 50 (FM50), 75 (FM25), and 100% (FM0) by SPC protein, and each replacement group was supplemented with 0.4% IMP to formulate five experimental diets. Each diet was randomly allocated to triplicate groups of fish (4.8 g) for 56 days. Results demonstrated that fish fed diet groups FM50 and FM75 had significantly the highest final weight, weight gain, specific growth rate, and feed intake. Meanwhile, in comparison to the control, growth performance and feed utilization did not significantly differ with the 75% FM-replaced diet group by SPC with IMP supplementation. Apparent digestibility coefficient of dry matter, protein, and lipid also followed a similar trend. All growth, feed utilization, and digestibility parameters were significantly lower in the FM0 diet group. Triglyceride level was increased (P < 0.05) with the increasing replacement level and it was significantly highest in the FM0 diet group. The fish fed diet groups FM100 and FM50 showed the best condition of oxidative and freshwater stress resistance, respectively. Meanwhile, the groups with up to 75% FM-replaced diet also showed acceptable stress resistance status. Overall, enhanced innate immune responses were observed in the entire FM replaced with IMP-supplemented diet groups in comparison to the control. Considering SGR as a model, the regression analysis determined that 71.7% FM protein could be replaced by SPC protein with IMP supplementation in diets for the growth of red sea bream.

Abstract
We determined the supplementation effects of dietary fucoidan on growth, immune responses, blood characteristics, and oxidative stress resistance of juvenile red sea bream. A fishmeal (FM)-based basal diet supplemented with 0% (D1, control), 0.05% (D2), 0.1% (D3), 0.2% (D4), 0.4% (D5), and 0.8% (D6) mozuku fucoidan to formulate six experimental diets. Each diet was randomly allocated to triplicate groups of fish (3.8 g) for 60 days. Results showed that fish-fed diet D5 showed significantly higher (P < 0.05) growth performance compared to the control (D1). Diet groups D2 to D4 also showed intermediate values compared to D1. Feed conversion efficiency and protein efficiency ratio were significantly higher in diet group D5, which was not significantly different with D3. Fucoidan supplementation increased whole-body lipid, which was significantly higher in the D5 group. Condition factor (CF) was significantly higher in fish fed ≥ 0.2% fucoidan-supplemented diet groups. Diet group D5 and D4 showed significantly lower blood urea nitrogen (BUN) and aspartate aminotransferase (AST) level, respectively. Dietary fucoidan reduced the oxidative stress of fish. Among the measured nonspecific immune parameters, only peroxidase activity (PA) and total serum protein (TSP) were significantly influenced by dietary supplementation and it was higher in D4 group. Fucoidan supplementation reduces thiobarbituric acid reactive substance (TBARS) values numerically and it was lowest in fish-fed diet group D5. Under the present experimental condition, finally, we concluded that 0.3-0.4% dietary fucoidan supplementation enhanced the growth and health performance of red sea bream by increasing growth, immune response, blood characteristics, and oxidative stress resistance.

Abstract
Both inosine (INO) and vitamin C (l-ascorbic acid, AsA) play important roles in growth performance, feed utilization and health status of fish. Therefore, a 56 days feeding trial was conducted to determine the interactive effects of dietary INO and AsA on growth performance, oxidative status, innate and adaptive immune responses of red sea bream. Fish growth performance and fed utilization parameters were significantly affected by dietary INO supplementation but not by AsA. Fish fed diets with INO at 4 g kg-1 diet in combination of high and low levels of AsA (3.1 g kg-1 and 9.3 g kg-1) produced the highest growth and feed utilization performances. In terms of growth and feed utilization performances no significant interaction effects were observed between INO and AsA. Dietary INO significantly influenced hematocrit, glucose and glutamyl oxaloacetic transaminase (GOT) content of red sea bream meanwhile AsA also significantly influenced hematocrit, glucose, total cholesterol, blood urea nitrogen (BUN) and glutamic-pyruvate transaminase (GPT) content of the test fish. No significant interaction effects was also observed between INO and AsA on measured hematological parameters. Reactive oxygen metabolites (d-ROMs) significantly influenced by both INO and AsA. Fish fed diet groups D1, D4 and D6 showed best oxidative stress resistance. Only INO was a significant factor on nitro-blue-tetrazolium activity (NBT) and bactericidal activity (BA). Neither INO nor AsA was a significant factor on serum catalase activity (CAT), total serum protein (TSP), peroxidase activity (PA) and lysozyme activity (LA). No significant interaction effects was observed between INO and AsA on measured innate immune parameters. Agglutination antibody titer was significantly influenced by dietary supplementation, after 15 days of vaccination but not in 21 days. In the day 15th fish and diet group D3 and D5 showed significantly higher values compared to diet groups control and D1. INO was the only significant factor of increasing agglutination antibody titer in 15 t h day. While AsA was not a significant factor on agglutination antibody titer values in day 15 t h, there was an interaction between dietary INO and AsA levels. Finally under the experimental conditions, fish fed high INO and low AsA levels (4 g kg-1 and 0.31 g kg-1 diet, respectively) showed best growth and feed utilization performance. Simultaneously, low level of INO and high level of AsA (2 g kg-1 and 0.93 g kg-1 diet, respectively) improved blood chemistry and immunological parameters. Furthermore, combined use of INO and AsA is possible to improve hemato-immunological responses of red sea bream.

Abstract
The bacterial wilt disease caused by Ralstonia solanacearum is an extremely destructive soil borne bacterial pathogen to potato. It appeared as rapid and fatal wilting symptoms in the host. The pathogen entered through different wounds and easily disseminated via infected biological material, soil, contaminated irrigation water, surface water, farm equipment etc. and could survive for many years in association with alternate hosts. It is a widely distributed and very much diversified soil borne pathogen having an unusually broad host range with long-term survivable ability. Direct yield losses caused by the pathogen varied from 30 to 90% depending on different factors such as cultivar, weather factors, soil type, cropping pattern and strain etc. Bacterial wilt continued to be an economically serious problem for field-grown potatoes in many tropical, subtropical and warmer areas of the world including Bangladesh. But the effectiveness of conventional management is limited because of some special biological features of the bacteria. Mostly protective methods and chemical control remain ineffective, antibiotics show hardly any effect, and efficacious biocontrol method has yet to be developed against the organism. However, during the recent decades, some natural bioactive compounds, viz. propolis, honey, turmeric, magnesium chloride, cow dung, aromatic rice extract, iodine, sodium bicarbonate etc. have got attention for their effectiveness in inhibiting a range of serious bacterial pathogens from both Gram positive and Gram negative types. As no conventional method has been found effective alone, such compounds could be tested for their effectiveness against the very successful soil borne bacteria to overcome the traditional management limitations.J.

Abstract
Background Adverse effects of antileishmanial drugs can affect patients’ quality of life and adherence to therapy for visceral leishmaniasis (VL) and post-kala-azar dermal leishmaniasis (PKDL). In Bangladesh, there are 26 treatment centers that manage leishmaniasis cases coming from 100 endemic upazilas (subdistricts) of 26 districts (these include VL, PKDL, treatment failure, and relapse VL and cutaneous leishmaniasis cases). This study aimed to investigate the feasibility of using focused pharmacovigilance for VL (VLPV) in Bangladesh’s National Kala-azar Elimination Programme for the early detection and prevention of expected and unexpected adverse drug reactions (ADRs). Methods This activity has been going on since December 2014. Activity area includes secondary public hospital or Upazila health complex (UHC) in hundred sub districts and Surya Kanta Kala-azar Research Center (SKKRC) in Mymensingh District, a specialized center for management of complicated VL and PKDL cases. Communicable Disease Control (CDC) of the Directorate General of Health Services (DGHS) assigned twenty five of hundred UHCs and SKKRC (total 26) as treatment centers depending on their suitable geographical location. This was implemented for better management of VL cases with Liposomal Amphotericin B (AmBisome®) to ensure patient convenience and proper utilization of this expensive donated drug. A VLPV expert committee and a UHC VLPV team were established, an operational manual and pharmacovigilance report forms were developed, training and refresher training of health personnel took place at UHCs and at the central level, collected information such as patient data including demographics, treatment history and response, adverse events were analyzed. This report includes information for the period from December 2014 to December 2016. Results From December 2014 to December 2016, 1327 leishmaniasis patients were treated and 1066 (80%) were available for VLPV. Out of these, 57, 33, 9, and 1% were new VL, PKDL, VL relapse, and other cases, respectively. Liposomal amphotericin B was mostly used (82%) for case management, followed by miltefosine (20%) and paromomycin (3%). Out of the 1066 patients, 26% experienced ADRs. The most frequent ADR was fever (17%, 176/1066), followed by vomiting (5%, 51/1066). Thirteen serious adverse events (SAEs) (eight deaths and five unexpected SAEs) were observed. The expert committee assessed that three of the deaths and all unexpected SAEs were possibly related to treatment. Out of the five unexpected SAEs, four were miltefosine-induced ophthalmic complications and the other was an AmBisome®-induced avascular necrosis of the nasal alae. The Directorate General of the Drug Administration entered the ADRs into the World Health Organization Uppsala Monitoring Centre (WHO-UMC) VigiFlow database. Conclusions This study found that VLPV through NKEP is feasible and should be continued as a routine activity into the public health system of Bangladesh to ensure patient safety against anti-leishmanial drugs.
