Abstract
Self- rated health (SRH) is a valuable screening-level measure of a community's health status. A better understanding of the factors that influence SRH is time-demanding and challenging. This study aims to examine the determinants of SRH by investigating health morbidities, demographic and socio-economic factors in Bangladesh perspective. This cross-sectional study was conducted among 908 adults (aged 18 years and above) in Manikganj district of central Bangladesh from 2nd January to 13th January 2017. Chi-square test was performed to test the association and binary logistic regression was performed to predict the relationship of SRH with all potential variables. The present study reveals the balance of bad health versus good health which was 27.2% and 72.8% respectively. Participants had at least one or more chronic diseases reported 3.40 times (p<0.001) bad health compared to those who did not have any chronic illness. In contrast, acute morbidity was not a significant determinant for SRH (OR=1.379, p=0.063). Older population aged 60 years and above had 3.96 times (p<0.001) higher chance of having self-reported bad health than the younger population. In addition, depression was also found a significant contributor (OR=2.05, p<0.001) to bad health. Chronic morbidity, older age and depression are the significant predictors of SRH. If SRH is used as a screening-level measure for the rural communities then the chronic disease status of rural Bangladesh will be identified quickly and easily.

Abstract
The level of thyroid hormones is often changed in uncontrolled diabetic patients. Screening for Thyroid dysfunction (TD) among patients with Type 2 Diabetes mellitus (T2DM) should be performed considering the increased prevalence of thyroid disorders. This cross-sectional comparative study was conducted in outpatient department of Endocrinology and Medicine, Mymensingh Medical College Hospital, Mymensingh (MMCH) from 1st March 2020 to 30th August 2021. One hundred (100) patients with type 2 diabetes along with 100 (hundred) non-diabetic controls of same age group were enrolled in the study. After taking clinical data, patients were investigated to estimate Fasting plasma glucose (FPG), serum free tri-iodothyronine (FT3), free thyroxin (FT4) and thyroid stimulating hormone (TSH) level to see thyroid dysfunction. Patients were selected with purposive sampling. Thyroid dysfunction was found to be more in T2DM (15.0%) in comparison with non-diabetic controls (5.0%) and this difference was statistically significant (p=0.018). In both diabetic and non-diabetic groups, subclinical hypothyroidism and hypothyroidism were the most common thyroid dysfunction. Thyroid dysfunction was found more in 40-60 years that suggests the prevalence of thyroid dysfunction are increasing in diabetic patients with advancing age. Thyroid dysfunction was found more among overweight and obese patient in both groups. Mean BMI was found higher among diabetic patient with thyroid dysfunction. Logistic regression showed significant association of Thyroid dysfunction with age >50 years and high FPG level. We found thyroid dysfunction was more prevalent in patients with T2DM than non-diabetics. So, screening for thyroid dysfunction among type 2 diabetic patients by estimating Serum TSH, FT4 level should be performed.

Abstract
Piperine is a natural alkaloid that possesses a variety of therapeutic properties, including anti-inflammatory, antioxidant, antibacterial, and anticarcinogenic activities. The present study aims to assess the medicinal benefits of piperine as an anti-diarrheal agent in a chick model by utilizing in vivo and in silico techniques. For this, castor oil was administered orally to 2-day-old chicks to cause diarrhea. Bismuth subsalicylate (10 mg/kg), loperamide (3 mg/kg), and nifedipine (2.5 mg/kg) were used as positive controls, while the vehicle was utilized as a negative control. Two different doses (25 and 50 mg/kg b.w.) of the test sample (piperine) were administered orally, and the highest dose was tested with standards to investigate the synergistic activity of the test sample. In our findings, piperine prolonged the latent period while reducing the number of diarrheal feces in the experimental chicks during the monitoring period (4 h). At higher doses, piperine appears to reduce diarrheal secretion while increasing latency in chicks. Throughout the combined pharmacotherapy, piperine outperformed bismuth subsalicylate and nifedipine in terms of anti-diarrheal effects with loperamide. In molecular docking, piperine exhibited higher binding affinities towards different inflammatory enzymes such as cyclooxygenase 1 (-7.9 kcal/mol), cyclooxygenase 2 (-8.4 kcal/mol), nitric oxide synthases (-8.9 kcal/mol), and L-type calcium channel (-8.8 kcal/mol), indicating better interaction of PP with these proteins. In conclusion, piperine showed a potent anti-diarrheal effect in castor oil-induced diarrheal chicks by suppressing the inflammation and calcium ion influx induced by castor oil.

Abstract
Christella dentata (Forssk.) Brownsey & Jermy has been commonly used in traditional medicinal practices but its effects on multi-drug-resistant (MDR) bacteria have remained unexplored. We aimed to assess the in vitro antibacterial potential of the ethanol extract of Christella dentata (EECD) against MDR Pseudomonas aeruginosa and to identify potential multi-targeting antibacterial phytocompounds through computer-aided drug design focusing on the LasR and LpxC proteins. PPS, FT-IR and GC-MS were used for profiling of the phytocompounds in EECD. The antimicrobial activity of EECD was assessed using in vitro agar well diffusion, disc diffusion, MIC and MBC. Computer-aided drug design was used to identify multi-targeting leads from GC-MS-annotated phytocompounds. EECD exhibited dose-dependent antibacterial activity and revealed the presence of 51 phytocompounds in GC-MS analysis. Among these, three phytocompounds; (2E,4E)-N-isobutylhexadeca-2,4-dienamide (CID 6442402), bicyclo[4.3.0]nonane, 2,2,6,7-tetramethyl-7-hydroxy- (CID 536446) and 1,4-diethylbenzene (CID 7734) were identified as promising antibacterial phytocompounds as they strongly bonded with LasR and LpxC. Of them, CID 536446 and CID 7734 exhibited multiple targeting abilities with LasR and LpxC. On further screening, both CID 536446 and CID 7734 exhibited favorable drug-able, pharmacokinetics and toxicity properties. Finally, molecular dynamics (MD) simulation proved the binding stability of bicyclo[4.3.0]nonane, 2,2,6,7-tetramethyl-7-hydroxy- and 1,4-diethylbenzene to active pockets of LasR and LpxC. The results of this study offer scientific validation for the traditional use of Christella dentata in bacterial infection-related diseases. It also suggests that bicyclo[4.3.0]nonane, 2,2,6,7-tetramethyl-7-hydroxy- and 1,4-diethylbenzene from Christella dentata might be responsible for the antibacterial activity and could act as phytopharmacological leads for the development of LasR and LpxC inhibitors against MDR P. aeruginosa.

Abstract
This study attempted to develop a low-cost and eco-friendly bio-based composite adsorbent that is highly efficient in capturing potential toxic metals. The bio-composite adsorbent was prepared using graphene oxide (GO), carboxymethyl cellulose (CMC) and chitosan (CS); and characterized using FTIR, SEM-EDX and WAXD techniques. Metal-ion concentration in an aqueous solution was measured by ICP-OES. This article reveals that the adsorption of heavy metal ions varied according to the adsorbent quantity, initial metal concentration, pH, and interaction time. The metal ions' adsorption capacity (mg/g) was observed to increase when the interaction time and metal concentration increased. Conversely, metal ions adsorption was decreased with an increase in adsorbent dosages. The effect of pH on metal ions' adsorption was ion-specific. The substantial adsorption by GO/CMC/CS composite for Co2+, CrO42-, Mn2+ and Cd2+, had the respective values of 43.55, 77.70, 57.78, and 91.38 mg/g under acidic conditions. The metal ions experimental data were best fitted with pseudo-second-order (PSO) kinetics, and Freundlich isotherm model (except Co2+). The separation factors (RL) value in the present investigation were found between 0 and 1, meaning that the metal ions adsorption onto GO/CS/CMC composite is favorable. The RL and sorption intensity (1/n) values fitted well to the adsorption isotherm.

Abstract
A significant portion of the human diet is comprised of fruits, which are consumed globally either raw or after being processed. A huge amount of waste and by-products such as skins, seeds, cores, rags, rinds, pomace, etc. are being generated in our homes and agro-processing industries every day. According to previous statistics, nearly half of the fruits are lost or discarded during the entire processing chain. The concern arises when those wastes and by-products damage the environment and simultaneously cause economic losses. There is a lot of potential in these by-products for reuse in a variety of applications, including the isolation of valuable bioactive ingredients and their application in developing healthy and functional foods. The development of novel techniques for the transformation of these materials into marketable commodities may offer a workable solution to this waste issue while also promoting sustainable economic growth from the bio-economic viewpoint. This approach can manage waste as well as add value to enterprises. The goal of this study is twofold based on this scenario. The first is to present a brief overview of the most significant bioactive substances found in those by-products. The second is to review the current status of their valorization including the trends and techniques, safety assessments, sensory attributes, and challenges. Moreover, specific attention is drawn to the future perspective, and some solutions are discussed in this report.

Abstract
Antioxidant compounds such as phenolics and carotenoids scavenge reactive oxygen species and protect against degenerative diseases such as cancer and cardiovascular disease when used as food additives or supplements. Mango peel is a by-product of mango which is a good source of bioactive substances such as phytochemicals, antioxidants, and dietary fibers. Unfortunately, the study on mango peel as a potential food additive is very limited. Accordingly, the present study aimed to develop functional noodles through extrusion technology with the encapsulation of mango peel powder as a natural source of bioactive compounds. First, mango peel powder (MPP) was prepared and incorporated during the mixing of ingredients before noodles formation at three different levels (2.5, 5 and 7.5 %). Afterward, the noodles were studied to determine how the encapsulated MPP affects the proximate composition, physicochemical characteristics, polyphenols, carotenoids, anthocyanin, antioxidant and antidiabetic activity, and sensory characteristics. The noodles exhibited a dose-dependent relationship in the content of bioactive components and functional activities with the encapsulation of MPP levels. A significantly (p 0.05) higher value was noticed in 7.5 % of MPP-encapsulated noodles than in any level of MPP encapsulation in noodles. The fiber and protein contents in the MPP-encapsulated noodles were increased by about 0-1.22 % and 0-3.16 %, respectively. However, noodles' color index and water absorption index were decreased with the level of MPP encapsulation. The cooking loss of noodles increased from 4.64 to 5.17, 6.49, and 7.32 %, whereas the cooked weight decreased from 35.11 to 34.40, 33.65, and 33.23 % with 2.5, 5.0, and 7.5 % of MPP encapsulation, respectively. However, MPP was stable during storage of noodles exhibiting higher phenolic content and antioxidant activity than control samples. The sensory evaluation showed that MPP-encapsulated noodles at levels 2.5 and 5 % had approximately similar overall acceptability values with the control sample. As a result of the findings, it appears that adding MPP up to 5 % to noodles improves their nutritional quality without changing their cooking, structural, or sensory aspects. Therefore, mango peel powder can be a potential cheap source for the development of functional noodles and food ingredients.

Abstract
BACKGROUND Vaccine hesitancy is a significant global health concern, and mass vaccination is essential in preventing the spread of COVID-19. Undergraduate students need to be prioritized for vaccination as they continue their academic curriculum physically. However, limited research explores vaccine hesitancy and acceptance among undergraduate students in Bangladesh. Therefore, this study evaluated vaccine hesitancy and acceptance among this population. METHOD A web-based cross-sectional study was conducted between May and June 2021 using a structured questionnaire to assess COVID-19 vaccine hesitancy and acceptance among undergraduate students in Bangladesh. The Oxford Covid-19 Vaccine Hesitancy Scale was used to measure vaccine hesitancy. The study used convenient sampling. RESULT Across the country, 334 undergraduate students participated in this study on COVID-19 vaccine acceptance, with a mean age of 22.4 years. Most participants were male and unmarried, most having spent four years at university. 89.52% of participants would accept a COVID-19 vaccine if it were suggested by educational institutions or available, while 4.49% refused to receive the COVID-19 vaccine. Participants showed low levels of vaccine hesitancy, with a mean score of 10.77 on the Oxford COVID-19 Vaccine Hesitancy Scale. Most participants had a positive attitude towards receiving the vaccine, with the majority wanting to get it as soon as it becomes available. No association was found between vaccine acceptance and participants' background characteristics. CONCLUSION Our study found a high level of vaccine acceptance among undergraduate students in Bangladesh, indicating that this group can be vaccinated quickly, significantly accelerating vaccination goals. However, further large-scale studies are recommended among vulnerable groups, including school and college students, to ensure vaccine preparedness.

Abstract
The photocatalytic reduction of Cr6+ to Cr3+ in an aqueous solution, using 3 wt% Ag/g-C3N4 in the presence of ethylenediaminetetraacetic acid (EDTA), has been investigated here. The photocatalytic reduction of Cr6+ with pure g-C3N4 was very low. The addition of Ag and EDTA can significantly improve the photocatalytic reduction of Cr6+ using g-C3N4. In the presence of EDTA, the efficiency with Ag/g-C3N4 was better than those with Au/g-C3N4 and Cu/g-C3N4. With EDTA, the reduction rate constant increased from 0.0005 for pure g-C3N4 to 0.12 min-1 for 3 wt% Ag/g-C3N4. By increasing the concentration of EDTA from 0 to 500 mg L-1, the reduction efficiency of Cr6+ increased extremely, and the rate constant raised from 0.008 to 0.12 min-1. The optimal EDTA concentration was 500 mg L-1 for the photocatalyst Ag/g-C3N4. The Ag-EDTA complex may be reduced to metallic silver by the conduction band electrons of g-C3N4. The electron-hole recombination was significantly suppressed by the electron trapping of Ag. EDTA may act in by the formation of Cr3+-complex and the separation of Cr3+ from the g-C3N4 surface and by the valence band hole scavenger of g-C3N4. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance spectroscopy (DRS) and photoluminescence spectra (PL) were used to characterize g-C3N4 and Ag/g-C3N4 nanoparticles. A possible mechanism for photocatalytic Cr6+ reduction has also been demonstrated.

Abstract
Obesity is a chronic multifactorial disease characterized by the accumulation of body fat and serves as a gateway to a number of metabolic-related diseases. Epidemiologic data indicate that Obesity is acting as a risk factor for neuro-psychiatric disorders such as schizophrenia, major depression disorder and vice versa. However, how obesity may biologically interact with neurodevelopmental or neurological psychiatric conditions influenced by hereditary, environmental, and other factors is entirely unknown. To address this issue, we have developed a pipeline that integrates bioinformatics and statistical approaches such as transcriptomic analysis to identify differentially expressed genes (DEGs) and molecular mechanisms in patients with psychiatric disorders that are also common in obese patients. Biomarker genes expressed in schizophrenia, major depression, and obesity have been used to demonstrate such relationships depending on the previous research studies. The highly expressed genes identify commonly altered signalling pathways, gene ontology pathways, and gene-disease associations across disorders. The proposed method identified 163 significant genes and 134 significant pathways shared between obesity and schizophrenia. Similarly, there are 247 significant genes and 65 significant pathways that are shared by obesity and major depressive disorder. These genes and pathways increase the likelihood that psychiatric disorders and obesity are pathogenic. Thus, this study may help in the development of a restorative approach that will ameliorate the bidirectional relation between obesity and psychiatric disorder. Finally, we also validated our findings using genome-wide association study (GWAS) and whole-genome sequence (WGS) data from SCZ, MDD, and OBE. We confirmed the likely involvement of four significant genes both in transcriptomic and GWAS/WGS data. Moreover, we have performed co-expression cluster analysis of the transcriptomic data and compared it with the results of transcriptomic differential expression analysis and GWAS/WGS.

Abstract
Traditional safety research mostly relies on accident data to analyze the precedents to a crash. Alternatively, surrogate safety measures have the potential to proactively evaluate safety events. The era of connected vehicles and smart sensing has brought about tremendous innovations in safety research. GPS data from such vehicles form a useful case of big data analytics where surrogate safety measures have largely been unexplored. In this paper, we propose time to collision estimation from connected vehicle GPS data. The vehicle dynamics such as speed, acceleration, yaw rate, etc. are then coupled with geometric and non-geometric roadway attributes to understand the contributing factors for a traffic conflict. The dataset contains 2,568,421 GPS points from 14,753 unique journeys. 1:4 ratio of conflict to non-conflict events was used to select 15,258 samples with 28 independent vehicle dynamics, geometric, and non-geometric variables. Binary logit model was used to investigate the relationship of these variables with conflicts. Model results showed that out of 28 independent variables, 6 independent variables and 7 interaction variables were found significant. The results showed some interesting and unique relations of these variables with conflicts. Based on these significant variables, k-means clustering was performed to understand the threshold for the significant values for which the number of conflicts is significantly increased. Results from k-means clustering and two sample binomial proportion t-tests revealed that when absolute acceleration crossed 0.8 m/s2, conflict probability increased by 8 percentage points. Moreover, when the yaw rate crossed 8 degrees/s, the conflict probability doubled. Besides, vehicles traveling at more than 140% of the recommended speed limit increased conflict probability by 7 percentage points.

Abstract
The silver pride of Bangladesh, migratory shad, Tenualosa ilisha (Hilsa), makes the highest contribution to the total fish production of Bangladesh. Despite its noteworthy contribution, a well-annotated transcriptome data is not available. Here we report a transcriptomic catalog of Hilsa, constructed by assembling RNA-Seq reads from different tissues of the fish including brain, gill, kidney, liver, and muscle. Hilsa fish were collected from different aquatic habitats (fresh, brackish, and sea water) and the sequencing was performed in the next generation sequencing (NGS) platform. De novo assembly of the sequences obtained from 46 cDNA libraries revealed 462,085 transcript isoforms that were subsequently annotated using the Universal Protein Resource Knowledgebase (UniPortKB) as a reference. Starting from the sampling to final annotation, all the steps along with the workflow are reported here. This study will provide a significant resource for ongoing and future research on Hilsa for transcriptome based expression profiling and identification of candidate genes.

Abstract
This study was conducted to develop a cell culture based PPR virus vaccine candidate using recent Bangladeshi strain of peste des petits ruminant's (PPR) virus. PPR virus was isolated from field outbreaks, confirmed by RT-PCR and used as viral inoculum for serial passaging in Vero cells for adaptation and attenuation. 60th serial passage had completed and RT-PCR and real time RT-PCR were done in every 5 passages for confirmation of PPR virus in tissue culture fluid (TCF). To assess the adaptation and attenuation cytopathology, virus titration, sequencing of both F and N genes and live animal experimentation were done. Different cellular alterations produced by PPR virus in infected Vero cells including syncytia formation, development of both intranuclear and intra cytoplasmic inclusion bodies and finally cell degradation are the indications of adaptation. The virus titre was found 2.5, 3.31, 3.55, 4.44, 4.71 and 6.5 Log10 TCID50/ml at 10th, 20th, 30th, 40th, 50th and 60th passages level respectively. In F gene sequence analysis it has been observed that few nucleotide (nt) and mino acid (aa) has been substituted as the effects of serial passaging of PPR virus in Vero cells. TCF at 60th passage level was found effective to produced protective antibody (Ab) titre in live animal experimentation. It is concluded that serially passaged and Vero cells adapted PPR virus TCF could be used as a vaccine candidate for further use to develop a potent & effective vaccine against PPR diseases.

Abstract
Core body temperature (CBT) regulation is crucial for mammalian wellbeing and survival. Cattle pant to dissipate excess heat to regulate CBT when ambient conditions exceed thermoneutral zones. However, to date, neither the variability in cattle heat response, the lagged response of CBT to thermal indices, nor the diurnal patterns of thermal indices, CBT and panting have been reported in the literature. We decomposed thermal indices, CBT and panting time-series data for 99 feedlot heifers across three discrete heat events into diurnal, trend and residual components. Both raw and decomposed data were analysed to explore the lagged CBT and panting responses and the association between series. We show ambient thermal conditions impact CBT with a 1-h lag despite a lag of between 1.5 to 3 h from raw data. Average individual panting scores were used to identify heat-susceptible and heat-tolerant cattle. Heat-susceptible cattle showed greater CBT (P < 0.01) between 8:00 and 23:00 and greater panting duration (P < 0.05) between 10:00 and 18:00 than heat-tolerant cattle under the same thermal conditions and these variations followed a similar pattern despite differences in cattle breed. This new information enables targeted amelioration and selection of individuals against heat susceptibility.

Abstract
OBJECTIVES We aimed to determine: (1) the prevalence and socio-economic distribution of undiagnosed, untreated, and uncontrolled diabetes mellitus (DM); (2) the relationship between socio-economic status (SES) and undiagnosed, untreated, and uncontrolled DM; and (3) if this relationship is mediated by gender. STUDY DESIGN Cross-sectional nationally representative household-based survey. METHODS We used data from the Bangladesh Demographic Health Survey from 2017 to 18. Our findings were based on the responses of 12,144 individuals aged 18 years and older. As a measure of SES, we focused on standard of living (hereinafter referred to as wealth). The study's outcome variables were prevalence of total (diagnosed + undiagnosed), undiagnosed, untreated, and uncontrolled DM. We used three regression-based approaches-adjusted odds ratio, relative inequality index, and slope inequality index-to assess different aspects of SES differences in the prevalence of total, undiagnosed, untreated, and uncontrolled DM. We used logistic regression analysis to look at the adjusted association between SES and the outcomes after gender stratification to see whether gender status moderates the association between SES and the targeted outcomes. RESULTS In our sample analysis, the age-adjusted prevalence of total, undiagnosed, untreated, and uncontrolled DM was 9.1%, 61.4%, 64.7%, and 72.1%, respectively. Females had a higher prevalence of DM and undiagnosed, untreated, and uncontrolled DM than males. When compared to people in the poor SES group, people in the rich and middle SES groups had 2.60 times (95% confidence interval [CI] 2.05-3.29) and 1.47 times (95% CI 1.18-1.83) higher chance of developing DM. When compared to individuals in the poor SES group, those in the rich SES groups were 0.50 (95% CI 0.33-0.77) and 0.55 times (95% CI 0.36-0.85) less likely to have undiagnosed and untreated DM. CONCLUSIONS In Bangladesh, rich SES groups were more likely than poor SES groups to have DM, whereas poor SES groups with DM were less likely than rich SES groups to be aware of their disease and obtain treatment. The government and other concerned parties are urged by this study to pay more attention to developing suitable policy measures to reduce the risk of DM, particularly among rich SES groups, as well as targeted efforts to screen for and diagnose DM in socio-economically disadvantaged groups.

Abstract
Halotolerant bacteria get adapted to a saline environment through modified physiological/structural characteristics and may provide stress tolerance along with enhanced growth to the host plants by different direct and indirect mechanisms. This study reports on multiple halotolerant plant growth-promoting rhizobacteria isolated from the coastal soils in Bangladesh, in fields where the halophytic wild rice Oryza coarctata is endemic. The aim was to find halotolerant bacteria for potential use as biofertilizer under normal/salt-stressed conditions. In this study, eight different strains were selected from a total of 20 rhizobacterial isolates from the saline-prone regions of Debhata and Satkhira based on their higher salt tolerance. 16S rRNA gene sequencing results of the rhizobacterial strains revealed that they belonged to Halobacillus, Bacillus, Acinetobactor, and Enterobactor genera. A total of ten halotolerant rhizobacteria (the other 2 bacteria were previously isolated and already reported as beneficial for rice growth) were used as both single inoculants and in combinations and applied to rice growing in pots. To investigate their capability to improve rice growth, physiological parameters such as shoot and root length and weight, chlorophyll content at the seedling stage as well as survival and yield at the reproductive stage were measured in the absence or presence (in concentration 40 or 80 mmol/L) of NaCl and in the absence or presence of the rhizobacteria. At the reproductive stage, only 50% of the uninoculated plants survived without setting any grains in 80 mmol/L NaCl in contrast to 100% survival of the rice plants inoculated with a combination of the rhizobacteria. The combined halotolerant rhizobacterial inoculations showed significantly higher chlorophyll retention as well as yield under the maximum NaCl concentration applied compared to application of single species. Thus, the use of a combination of halotolerant rhizobacteria as bioinoculants for rice plants under moderate salinity can synergistically alleviate the effects of stress and promote rice growth and yield.

Abstract
Acute myocardial infarction (AMI) patients characterize a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. Hypomagnesemia is a long-term risk factor for incident of both myocardial infarction and arrhythmia. We assessed whether serum magnesium levels at admission is associated with arrhythmias and in-hospital mortality in patients with acute myocardial infarction (AMI). The aim of the study was to evaluate the prognostic implications of serum magnesium level in patients with acute myocardial infarction. This cross-sectional observational study was conducted in the department of cardiology in Mymensingh Medical College Hospital from October 2017 to March 2019. Total 259 acute myocardial infarction patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group-I: Patients with acute myocardial infarction with serum magnesium ≥1.82mg/dl. Group-II: Patients with acute myocardial infarction with serum magnesium <1.82mg/dl. Serum magnesium level was measured on admission, and the incidence of in-hospital major cardiac events was assessed. In this study mean serum magnesium level of Group-I, Group-II were 2.21±0.14mg/dl, 1.60±0.15mg/dl respectively. It was statistically significant (p<0.05). In-hospital outcomes of the study group revealed that low risk group patients were uneventful outcome during hospitalization period, they had no any complication. In Group-I patient, 9(4.8%) were developed arrhythmias, 26(13.9%) were developed heart failure, 9(4.8%) were developed cardiogenic shock and 3(1.6%) were died and in Group-II patient, 44(61.10%) developed arrhythmias, 9(12.50%) were developed heart failure, 7(9.7%) were developed cardiogenic shock and 12(16.7%) were died out of them which was statistically significant (p<0.05). Mean duration of hospital stay of the study population according serum magnesium level was in Group-I, 4.27±0.68 days, in Group-II, 5.84±1.05 days which was statistically significant (p<0.05). In conclusion patient with serum magnesium level less than 1.82mg/dl increased the risk of in-hospital arrhythmia and death.

Abstract
Abstract
Although Doxorubicin is the standard of care in advanced soft tissue sarcomas, therapeutic efficacy is minimal. A major contributing factor appears to be an immunosuppressive tumor microenvironment (TME). We have shown that liposomal alendronate, an amino-bisphosphonate, can remodel the immunosuppressive TME towards an immune-permissive milieu. We postulate that co-encapsulating alendronate with doxorubicin in pegylated liposomes (PLAD) will increase the efficacy of doxorubicin as alendronate abrogates the activity of suppressive myeloid cells and liposomes facilitate the accumulation of drugs in tumors. PLAD was formulated with hydrogenated soybean phosphatidyl-choline, methoxy-polyethylene glycol2000-distearoyl-phosphatidylethanolamine, and cholesterol at a molar ratio of 55:5:40, with 1 mg/ml doxorubicin and 0.43 mg/ml alendronate. WEHI-164 fibrosarcoma cells were implanted subcutaneously in male balb/c mice. For assessing the tumor immunologic milieu, mice were randomized when tumor size reached ~300 mm3 to receive PLAD, pegylated liposomal doxorubicin (PLD), or free doxorubicin (FDox) at 8 mg/kg of doxorubicin (n=9/group) or vehicle (n=5) IV. Tumors were collected 5 days post-treatment for FACS analysis. To assess antitumor efficacy, mice were randomized when tumor size reached ~150 mm3 to receive PLAD, PLD, or FDox at 5 mg/kg of doxorubicin (n=9/group) or vehicle (n=5) IV weekly and euthanized at humane endpoints. PLAD, and to a lesser extent PLD, shifted cellular drug uptake to tumor-associated macrophages (TAM) and to monocytic myeloid-derived suppressor cells (mMDSC) compared to free doxorubicin which had cellular drug uptake below detectable levels. PLAD and PLD were associated with fewer total TAMs and a decreased polarization to pro-tumoral M2-TAMs compared to free doxorubicin. Only PLAD significantly increased tumor infiltration of antigen cross-presenting dendritic cells, while both PLAD and PLD significantly increased the number and functionality of NKT and NK cells that are consistent with enhanced antitumor immune responses in the TME. All treatments significantly reduced regulatory T cell infiltration which could help promote antitumor responses in the TME. Interestingly, FDox treatment induced significant changes in the TME that could diminish antitumor immune responses by decreasing M1 TAMs and NK cells. These effects are reflected in the therapeutic study which demonstrates that PLAD and PLD inhibited tumor growth and significantly prolonged survival, while free doxorubicin showed little or no anticancer activity in this advanced fibrosarcoma model. We found that liposomal delivery is required for effective drug uptake by the TAMs and mMDSCs. Co-encapsulation of alendronate and doxorubicin led to a remodeling of the TME by abrogating pro-tumoral immune responses. This strongly suggests that the PLAD formulation is a promising liposome-based drug carrier to potentiate immunotherapy in synergy with its cytotoxic effects.

Abstract
Increase platelet count can accompany various cancers including lung cancer. This finding has recently been suggested to indicate poor prognosis. In patients with malignancies, thrombocytosis has previously been related disease stage, histological type and survival. In this study, the prevalence of thrombocytosis and the prognostic information provided by platelet count were analyzed in patients with stage IV Non-Small Cell Lung Cancer (NSCLC) with an aim to assess elevated platelet count as a prognostic factor in patients with stage IV NSCLC and to investigate whether there is relationship between thrombocytosis, other clinico-pathologic factors and median survival. This prospective observational study was conducted in National Institute of Cancer Research and Hospital (NICRH), Dhaka, Bangladesh from September 2019 to August 2020. A total of 108 patients were enrolled purposively. Detail history taking, thorough physical examination was done along with relevant investigations. Data were collected by semi structured questionnaire and analysis was done with the help of Statistical Package for Social Science (SPSS), version 21.0. The mean age of the patients was found 56.4±12.2 years with range from 35 to 75 years. Majority (79.6%) patients were male, 52.8% patients came from low income and 36.1% were farmer. Majority (40.7%) were symptomatic; in bed >50.0% of day. Almost two third (59.3%) had <5.0% weight loss. Almost three fourth (69.4%) had squamous cell carcinoma. At the time of first assessment 75(69.4%) patients had normal and 33(30.6%) had elevated platelet count level. Age, sex and histological type were statistically not significant between normal and elevated platelet count level groups. But performance status, weight loss were statistically significant (p<0.05) between two groups. According to univariate analysis, age, performance status at presentation, weight loss more than 10.0% for 3 months and platelet count prior the start of treatment were all significant predictors for the overall survival. In multivariate analysis age, performance status at presentation and initial thrombocytosis were independent prognostic determinants for overall survival. Median survival time was significantly higher for the normal platelet count group and elevated platelet count group (7.5 months versus 5.5 months) respectively (95% CI, 5.5-7.5), p<0.001. The frequency of thrombocytosis in patients with stage-IV NSCLC at first presentation was 30.6% and median survival time in these patients was significantly shorter compared in patients without thrombocytosis. These results concluded that an elevated platelet count could be a useful prognostic factor for survival in patients with stage-IV NSCLC.

Abstract
Patients with HIV or AIDS suffer from wide varieties of complications that are related to infection. The eye as an organ is not spared from HIV-related manifestations. The ocular manifestations can be the presenting sign of a systemic infection in an otherwise asymptomatic HIV-positive person. The disease can have adnexal, anterior segment, posterior segment, orbital and neuro-ophthalmic manifestations. The objective of the study was to evaluate the ophthalmological manifestations among adult HIV infected patients of Bangladesh and co-relate the findings with CD-4+ T cell count. This cross sectional study was conducted in the department of Community Ophthalmology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to September 2015. Purposive sampling technique was applied to enroll the patients. Total 110 patients were enrolled regardless of their immunological status by inclusion and exclusion criteria. Relevant clinical evaluation including history & physical examinations, laboratory investigations and some ocular examinations like- visual acuity, slit lamp biomicroscopy, IOP, indirect ophthalmoscopy with +90D (diopter) and +20D were done. The age of the study population ranged from 20-58 years with mean±SD 37.63±8.16 years. Among the study population 67(60.9%) were male and 43(39.1%) were female. According to ART status, 58(52.7%) were on ART and 52(47.3%) were ART naive. The mean CD4+ T- cells count was 410±281.65 with minimum to maximum was 6-1266 cells/μl. Among them 53(48.2%) had HIV related ocular findings and 57(51.8%) had no HIV related ocular manifestation. In relation with CD+ T- cells count, highly significant relation was found with lower CD4+ T- cells count and ocular manifestation (p=0.001).

Abstract
Yard waste is one of the key components of municipal solid waste and can play a vital role in implementing zero-waste strategy to achieve sustainable municipal solid waste management. Therefore, the objective of this study is to predict yard waste generation using the grey theory from the predicted municipal solid waste generation. The proposed model is implemented using municipal solid waste generation data from the City of Winnipeg, Canada. To identify the generation factors that influence municipal solid waste generation and yard waste generation, a correlation analysis is performed among eight socio-economic factors and six climatic factors. The GM (1, 1) model is utilized to predict individual factors with overall MAPE values of 0.06%-10.39% for the in-sample data, while the multivariable GM (1, N) grey model is employed to forecast the quarterly level of municipal solid waste generation with overall MAPE values of 5.64%-7.54%. In this study, grey models predict quarterly yard waste generation from the predicted municipal solid waste generation values using only twelve historical data points. The results indicate that the grey model (based on the error matrices) performs better than the linear and nonlinear regression-based models. The outcome of this study will support the City of Winnipeg's sustainable planning for yard waste management in terms of budgeting, resource allocation, and estimating energy generation.

Abstract
Thyroid swellings are common clinical problem throughout the world and also in Bangladesh. Most of thyroid swellings are multinodular, but a good percentage is solitary thyroid nodule. There is no robust, feasible method for malignancy differentiation has not been well established. The study evaluated thyroid nodules for risk of malignancy and compared history, clinical, sonographic features and FNAC findings with histopathology. This was a cross sectional study on 160 consecutive subjects of thyroid nodules done in the department of ENT and Head Neck Surgery of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh during from July 2018 to December 2019. All patients were admitted and diagnosed by detail history, clinical examination, investigations and underwent thyroidectomy. Detailed history, clinical examination, ultrasonographic finding and FNAC variables were documented retrospectively and a mathematical model was established for malignancy prediction. In this study mean age of the patients of thyroid nodules was 37.54±11.49 years and majority of the patients were within 21-40 years of age. Frequency of thyroid nodules is more in female with male female ratio 1:7. Most of the thyroid nodules appeared in this study within 0-2 years (61.9%). In this series of thyroid nodules constituted 88.1% firm, 8.8% hard, 3.1% cystic. Among the patients 89(55.6%) cases have solitary thyroid nodule and 71(44.4%) cases have multinodular goitre Majority of the nodules were warm 57.5% followed by cold 42.5%. FNAC showed nodular goitre 72.5%, Follicular neoplasm 1.3%, Papillary carcinoma of thyroid 7.5%, colloid goitre 9.4%, suspicious papillary carcinoma 3.8% and lymphocytic thyroiditis 1.3%. In this study out of 85 solid nodule, 69(81.18%) were benign and 16(18.82%) was malignant and out of 3 cystic nodule 3(100%) were benign. In this study most of the benign and malignant nodules were predominantly solid. Study showed the malignancy is significantly (p=0.001) more in solid than cystic nodules. Final diagnosis in this study was done on the basis of histopathological reports. Out of 160 patients, histopathologically benign lesion was 120(75%) and malignant was 40(25%). Among malignant cases 36(22.5%) cases were papillary carcinoma, 1 case was medullary carcinoma and 3 cases were follicular carcinoma.

Abstract
Rapid spread of multidrug resistant microorganisms is a matter of great concern throughout the glove including Bangladesh. The objective was to identify the causative organisms for urinary tract infection (UTI) and their sensitivity patterns to antibiotics. This descriptive cross-sectional study was conducted on patients admitted with UTI (n=60) at a tertiary level hospital in Dhaka, Bangladesh from March 2019 to September 2019. Data were collected through clinical record reviews. Data of all these 60 cases were analyzed for socio-demographic characteristics. Of the 60 patients, culture and sensitivity report was available for 42 patients. Therefore, data were further analyzed for these 42 cases. Median age of patients was 35 years and 80% were female. The main organisms isolated from urine culture of UTI patients were E. coli (64%), Klebsiella (12%) and Enterococci species (10%). Susceptibility to antibiotics was analyzed only for E. coli (n=27) since the number of isolates of other organisms were small. E. coli was found to be resistant to most of the first- and second-line antibiotics, such as Amoxicillin (100%), Amoxyclav (72%), Co-trimoxazole (89%), Nalidixic acid (78%), Ceftazidim (94%), Ceftriaxone (73%), Cefuroxime (100%), Ciprofloxacin (59%), Cephotaxime (80%), Cefixime (100%) and Moxifloxacin (100%). E. coli was the predominant organism responsible for UTI and was resistant to most of the first- and second-line antibiotics. Immediate action is needed to develop empirical guideline for empirical management of UTI and establish surveillance system for monitoring.

Abstract
Low-income countries (LICs) and lower-middle-income countries (LMICs) are still deprived of the optimum doses of coronavirus disease 2019 (COVID-19) vaccines for their population, equal access and distribution, as well as mass immunization roadmaps to be implemented for achieving herd immunity and protection from the ongoing pandemic. In this short report, we are interacting with the world public health experts, as well as national and global leaders for warranting the mass vaccination drive to be more progressive against COVID-19 with equitable access of vaccines to LICs or LMICs to save the lives of the poorest country people and refugees. From several scientific databases, such as Google Scholar, PubMed, as well as national and international news websites, the data were collected data by utilizing appropriate keywords regarding the topic. Bangladesh might be exemplified in this brief communication as the representative of LMIC. As of October 14, 2021, 48% of the world's people have received at least one dose of the COVID-19 vaccine. In contrast, only 2.5% of people from LICs have come in under COVID-19 vaccination for at least a single shot. Both LICs and LMICs need far more vision and ambition, including political, administrative, and diplomatic progress along with enhancing the vaccination drive for their population to be immunized through simultaneous mass vaccination progress of other countries with implementing public health safety measures against the COVID-19 pandemic.

Abstract
Fungal infection of the ear canal is called Otomycosis. It is more common in hot and humid condition. There are many modalities of treatment or therapeutic agent for treatment of otomycosis. Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream is a topical antifungal agent described to be effective in the treatment of otomycosis. This study was performed to compare the efficacy of topical application clotrimazole 1% solution and Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream in the treatment of otomycosis. A controlled, randomized and open clinical trial was carried out in ENT department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2020 to July 2020. Patients diagnosed with fungal otitis externa who were treated with topical antifungals were included in this study. They were randomized into two treatment groups: i) Clotrimazole 1% solution, 2) Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream. Patients were microscopically evaluated at two weeks of treatment to determine resolution of disease. Recurrence and complications were recorded. Demographic and clinical variables were collected and analyzed, follow up and final outcomes (absence of infection) were compared between two groups. One hundred & two (102) patients were included, 51 in the clotrimazole 1% solution group and 51 in the Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream group. Predominant symptoms are pain, pruritus, aural fullness and hearing loss. Aspergillus organism was isolated most frequently (63.73%). Treatment with clotrimazole 1% solution groups resulted in 88.23% resolution vs. 80.39% resolution with Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream at 2 weeks of treatment. Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream group demonstrated higher treatment failure 11.76 and 19.60 respectively. Clotrimazole 1% solution is more effective than Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream for uncomplicated otomycosis. More study is needed to corroborate our results.

Abstract
Multi-drug resistant Typhoid fever (resistant to previously used chloramphenicol, ampicillin, amoxicillin, and trimethoprim-sulfamethoxazole) has been commonly described in the South East Asia region and a recent report suggests that the salmonella typhi have reduced response to fluoroquinolones (nalidixic acid-resistant). The optimum treatment protocol for this type of serovar has not been established. This study compared different antimicrobial regimens for the treatment of uncomplicated typhoid fever which was conducted in the medicine ward of Dhaka Medical College Hospital (DMCH) and outdoor setting in private practice in Dhaka metropolitan city, Mymensingh and Sylhet town from January 2017 to December 2017. Bangladeshi adults with uncomplicated typhoid fever were included in this an open-label randomized controlled trial. Ciprofloxacin (20mg/kg of body weight/day for 14 days), azithromycin (20mg/kg/day for 14 days), and Cefixime (16mg/kg/day for 14 days) were compared. Of the 81 enrolled patients, 62 were eligible for analysis (61 S. enterica serovar Typhi, 1 Salmonella enterica serovar paratyphi A). Of the S enterica serovar Typhi isolates, 88.7% (55/62) were MDR and 93.5% (58/62) were nalidixic acid resistant (NAR). The clinical cure rate was 62% (13/21) with ciprofloxacin, 71% (15/21) with Cefixime, and 85% (17/20) with azithromycin (p=0.053). The mean (95% confidence interval [CI]) fever clearance time for patients treated with azithromycin (5.8 days [5.1 to 6.5 days]) was shorter than that for patients treated with cefixime (7.1 days [6.2 to 8.1 days]) and ciprofloxacin (8.2 days [7.2 to 9.2 days]) (p<0.001). All three antibiotics were well tolerated. A 7-day course of azithromycin can be successfully used in uncomplicated typhoid fever due to isolates of MDR S enterica serovar Typhi.

Abstract
The present effort was to obtain extracts from various fruit by-products using three extraction systems and to evaluate their polyphenolic content, antioxidant, and α-glucosidase inhibition activity. The fruit by-products were pre-processed by washing, drying, and milling methods to produce the powder. The powder samples were used to obtain extracts using pressurized hot-water (PHWE), enzyme-assisted (EnE) and organic solvent extraction (OSE) systems. The total phenolic content (TPC), total flavonoid content (TFC), antioxidant and α-glucosidase inhibition activity in all samples were assessed by Folin-Ciocalteu, AlCl3 colorimetric, DPPH· & ABST·+ and α-glucosidase inhibitory methods. The results showed that the extracts of peel, seed and other by-products exhibited outstanding TPC, TFC, and strongest antioxidant and α-glucosidase inhibition activity, eventually higher than edible parts of the fruits. For instance, the highest TPC among the peels of various fruits were in mango peel (in all cultivar) followed by litchi peel, banana peel cv. sagor, jackfruit peel, pineapple peel, papaya peel, banana peel cv. malbhog and desi on average in all tested extraction systems. PHWE system yielded significantly (p < 0.05) higher TPC and TFC than other extraction systems. In case of misribhog mango variety, the TPC (mg GAE/g DM) in peels were 180.12 ± 7.33, 73.52 ± 2.91 and 36.10 ± 3.48, and in seeds were 222.62 ± 12.11, 76.18 ± 2.63 and 42.83 ± 12.52 for PHWE, EnE and OSE respectively. This work reported the promising potential of underutilized fruit by-products as new sources to manufacture ingredients and nutraceuticals for foods and pharmaceutical products.

Abstract
The most devastating pandemic of this era coronavirus disease-2019 (COVID-19) is caused by a novel virus named severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Although it is primarily a respiratory pathogen, it can also result in several extra-pulmonary manifestations includes gastrointestinal symptoms, hepatocellular injury. Angiotensin-converting enzyme-2 (ACE-2) receptor and transmembrane serine protease 2 (TMPRSS2), the entry receptor for the causative coronavirus SARS-CoV-2 is co-express in the gastrointestinal tract, hepatocyte, and cholangiocytes similar to the respiratory mucosa. The presence of these receptors facilitates the entry into the tissue and causes direct viral tissue damage, which is a proposed mechanism of injury. Diarrhoea, nausea, vomiting, abdominal discomfort are common gastrointestinal manifestations, whereas derangement of liver function tests is the most hepatic manifestation in COVID-19. In this article, we reviewed on SARS-CoV-2 disease COVID-19 regarding gastrointestinal, hepatic, and pancreatic manifestation, the mechanisms by which the virus may inflict damage, and their management perspective.

Abstract
In this research work, we propose macronutrients incorporated slow-release based nano-fertilizer using nanozeolite as a carrier. A simple chemical approach was used to synthesis the proposed nanozeolite composite fertilizer (NZCF). To gain an insight into the properties, morphology and structure of the synthesized NZCF, it was further characterized by different techniques such as powder XRD, FT-IR, SEM, and TG/DTA. A considerable enhancement of the quality and the water retention capacity of the soil was observed as a result of applying the proposed NZCF when compared with a commercial fertilizer. Furthermore, the swelling ratio and the equilibrium water content of NZCF were compared to the commercial fertilizer and their effect on plant growth was observed. Slow-release studies were carried out for both NZCF and the commercial fertilizer. The results of these studies reveled that NZCF possessed a long-term release pattern of the macronutrients and that showed a great potential for promoting plant growth. Hence, the prepared nanocomposite fertilizer can be safely used as an environment-friendly source of nutrients to enhance plant growth.

Abstract
A deep understanding of the common patterns of bug-fixing changes is useful in several ways: (a) such knowledge can help developers in proactively avoiding coding patterns that lead to bugs and (b) bug-fixing patterns are exploited in devising techniques for automatic bug localization and program repair.
This work includes an in-depth quantitative and qualitative analysis over 4,653 buggy revisions of five software systems. Our study identifies 38 bug-fixing
edit
patterns and discovers 37 new patterns of nested code structures, which frequently host the bug-fixing edits. While some of the
edit
patterns were reported in earlier studies, these
nesting
patterns are
new
and were never targeted before.

Abstract
Nanoparticle-based anticancer medications were first approved for cancer treatment almost 2 decades ago. Patients benefit from these approaches because of the targeted-drug delivery and reduced toxicity, however, like other therapies, adverse reactions often limit their use. These reactions are linked to the interactions of nanoparticles with the immune system, including the activation of complement. This activation can cause well-characterized acute inflammatory reactions mediated by complement effectors. However, the long-term implications of chronic complement activation on the efficacy of drugs carried by nanoparticles remain obscured. The recent discovery of protumor roles of complement raises the possibility that nanoparticle-induced complement activation may actually reduce antitumor efficacy of drugs carried by nanoparticles. We discuss here the initial evidence supporting this notion. Better understanding of the complex interactions between nanoparticles, complement, and the tumor microenvironment appears to be critical for development of nanoparticle-based anticancer therapies that are safer and more efficacious.

Abstract
Oral submucous fibrosis (OSF) is a chronic complex potentially pre-malignant condition caused by chewing areca nut and other irritants. It is an insidious process characterized by Juxta-epithelial deposition of fibrous tissue in the oral cavity and pharynx. OSF is very common in Southeast Asia and also now a days increase in Europe and North America. The aim of this study to compare the effectiveness of intralesional injection of triamcinolone and hyalurunidase versus intralesional injection of triamcinolone plus injection hyalurunidase with oral colchicine. The study included 60 patients of clinically diagnosed case of oral submucous fibrosis. Patients were divided into two Groups A and B. Group A patients received combination intralesionsl injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml. 15 days interval in 3 months and Group B received intralesional injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml in each 15 days interval for 3 months with oral colchicine 0.5mg twice daily for 3 months. Diagnosis based on burning sensation of mouth, blanching of mucosa, ulceration in oral cavity and also reduced mouth opening. Follow up assessment was done at intervals 1st follow up on 21st days after starting of treatment then 2nd follow up after 3 months and last 3rd follow up after 6 months. Before starting of treatment all patients were properly explained about the study and took their written consent. Much more improvement occurred in Group B patients, reducing in burning sensation and also increases in opening of mouth. In both groups blanching mucosae were improved. Treatment regimen of Group B is more effective in increasing mouth opening and improves burning sensation of oral cavity. No side effects were seen in both groups' patients.

Abstract
The timing of eating, relative to when feed is offered, is affected by the social rank of feedlot cattle due to limited feed bunk space. As cattle can select feed based on dietary preference, the timing of eating for cattle in feedlot may be associated with the ingested diet composition. Our objectives were to determine the nutritive value and timing of feed ingested by 100 feedlot cattle during transition and the association of timing of eating with feeding behaviours and average daily gain (ADG). Cattle behaviour and timing of eating were determined on 100 feedlot cattle using accelerometer-based ear tag sensors from days 3 to 6 post feedlot induction (observation period), and the ongoing impact of this period on ADG was determined for the full feed period (75 days). To determine eating patterns at the time of feed offer, cattle were grouped according to the number of days they were recorded as eating within 1 h of feed being offered across 4 observation days, G0: not present across 4 days, G1: present for 1 day, G2: 2 days, G3: 3 days and G4: present for each of the 4 days. Total mixed ration (TMR) samples were collected for nutritive value analysis from four locations along the feed bunk from the time feed was offered and at hourly intervals thereafter for 7 h each day during the observation period. The composition of feed in the bunk changed across the 7 h of measurement (P < 0.05). The DM and CP of feed increased from 65 to 70% and 15 to 16%, respectively, and the NDF decreased from 36 to 32%. Thus, the preferred TMR feed component was the fibrous dietary fraction. However, the overall composition of the ingested diet for 7 h post feeding was similar between groups. Cattle in G0 had reduced eating time (0.7 vs 4.8%; P < 0.001), rumination time (4.5 vs 19.5%; P < 0.001) and ADG (1.0 vs 1.3 kg/d; P < 0.05) across the study, as compared with cattle in G4. Offering a more fibrous ration during feedlot transition, and customised cattle segregation and/or customised feeding regimes based on sensor derived feeding behaviour profiles during acclimation to feedlot can optimise ADG, animal welfare and feedlot profit.

Abstract
The photocatalytic reduction of toxic Cr(VI) to non-pernicious Cr(III) using ZnFe2O4/EDTA (ethylenediaminetetraacetic acid) under UV irradiation was evaluated. The reduction of Cr(VI) with bare ZnFe2O4 under UV irradiation was negligible. However, the Cr(VI) in the solution was completely reduced within 3 h after the introduction of EDTA. EDTA could consume valence band holes and could be oxidized by holes into inorganic products. Therefore, photo-generated electrons could be used to reduce Cr(VI) to Cr(III). The effect of concentration of EDTA, ZnFe2O4 photocatalyst dosages, and initial pH on the photocatalytic reduction of Cr(VI) was investigated. The results revealed that the photocatalytic reduction of Cr(VI) accelerated by increasing EDTA concentration and ZnFe2O4 dosage. The present reduction process confirms the pseudo-first-order kinetic reaction. The quasi reduction rate constant increased from 3.5 x 10-4 min-1 to 2.6 x 10-2 min-1 with the increase in initial EDTA concentration from 0 to 1000 mg L-1. The acidic solution is preferable for the photocatalytic reduction of Cr(VI). The entire reduction of Cr(VI) was carried out within 2 h under the optimum conditions with pH 2, 20 mg ZnFe2O4, and 500 mg L-1 EDTA. The formation of [Cr-EDTA]3+ complex may be advantageous to accelerate the Cr(VI) reduction. A probable mechanism for the photocatalytic Cr(VI) reduction was speculated here.

Abstract
Diabetic retinopathy (DR) is the most frequent microvascular complication of diabetes mellitus (DM). DR remains a leading cause of blindness, currently accounting for 4.8% of the world's 37 million blindness cases. DR is one of the critical preventable causes of blindness. In Bangladesh, the number of studies reporting the prevalence and risk factors of DR in type 2 DM (T2DM) is limited. We conducted this cross-sectional study in a tertiary hospital in Bangladesh from March 2017 to August 2019 among 200 patients with T2DM for the presence and severity of DR by using color fundus photography in a dilated pupil. The diagnosis and grading of DR were made using the Early Treatment of Diabetic Retinopathy Study (ETDRS) Chart. Out of 200 subjects with T2DM, 35.5% had DR; the frequencies of NPDR and PDR were 19.0% and 16.5%, respectively. The mean age, diabetes duration, FPG, HbA1c, TG, TC, LDL-C, and serum creatinine were statistically higher, and eGFR was lower in the study subjects with DR than those without DR; BMI and HDL-C were indifferent in the two groups. The frequencies of males, subjects having monthly income of 10,000 Bangladeshi Taka (BDT) or more, smokers, hypertensives, and subjects having uncontrolled diabetes (HbA1c ≥7%), were higher in the DR group than the no DR group. Higher age (≥50 years), higher monthly income (≥10,000 BDT), urban residence, smoking, uncontrolled diabetes, and high LDL-C (≥100mg/dL) were found to be independent risk factors of DR in the study subjects. A large-scale nationwide study is needed to find out the actual prevalence of DR in Bangladesh.

Abstract
This prospective study was conducted at Department of ENT, Mymensingh Medical College Hospital, a tertiary care center in Bangladesh January 2017 to December 2018 to report hearing results and post operative complications of cartilage interposition ossiculoplasty in one-stage intact canal wall (ICW) tympanoplasty for cholesteatoma where ossicular chain is eroded or has to be removed either partially or totally. Total 42 patients underwent Intact canal wall (ICW) tympanoplasty for cholesteatoma with at least intact stapes footplate and in conjunction, cartilage ossiculoplasty was done during the same procedure. Patients were followed up regularly at 1 week, 1 month, 3 month, 6 month and at 1 year as usual follow up protocol to note complications and hearing status in 1 year follow up. In intact stapes suprastructure group, in the preoperative period, the mean air conduction thresholds (AC), bone conduction threshold (BC) and air-bone gap (ABG) were 48.3db, 9.5db and 38.8db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG were 27.6db, 9.7db and 17.9db respectively. In missing stapes supra structuregroup, in the preoperative period, the mean air conduction thresholds (AC), Bone conduction threshold (BC) and air-bone gap (ABG) were 57.4db 13.5db and 43.9db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG, were 33.9db, 14.2db and 19.7db respectively. For management of cholesteatoma cases, cartilage ossiculoplasty can be done effectively in conjunction with of intact canal wall tympanoplasty in a single setting. Complications are a few and easily manageable. Hearing results are at least as good as with other prosthesis and helps in avoiding subsequent surgery, discomfort and cost to the patients.

Abstract
Type 2 diabetes considered as a compound of metabolic syndrome. It can cause both micro and macrovascular complications. Diabetes is a strong risk factor in the development of atherosclerosis and likewise carotid artery disease. Carotid artery stenosis may cause stroke. Doppler ultrasound is the most common imaging technique for the diagnosis of carotid disease. Objective of the study was to assess the percentage of atherosclerotic carotid disease in asymptomatic Type 2 diabetics (T2D) by Doppler sonography and to find out the association of different risk factors of diabetic patient with atherosclerosis. A cross sectional study was done. A total of 43 type 2 diabetic patients (27 male, 16 female) referred from the out patient department and admitted patients in Mymensingh Medical College Hospital (MMCH) during January 2017 to December 2017 for the purpose of evaluation of intima media thickness (IMT) and carotid artery stenosis by Duplex color Doppler ultrasonography examination were enrolled in this study. Patients with previous history of recent stroke or transient ischemic attack (<6 weeks), history of carotid surgery or cervical radiotherapy were excluded. Carotid artery disease was found 65.1% in asymptomatic type 2 diabetics. Among them increased IMT in 48.8% and carotid stenosis was present in 37.2% and >50% stenosis (Peak systolic velocity >125cm/sec) was present in 9.3%. Age >50% years, smoking, duration of DM >10 years, hypertension, history of ischaemic heart disease and history of diabetic retinopathy were found to be associated with carotid atherosclerosis as well as carotid stenosis. High percentage of carotid artery disease (65.1%) was found in asymptomatic type 2 diabetes mellitus. This result suggests the need for carotid Doppler evaluation of all Type 2 diabetics as a first measure of stroke prevention, with the hope that timely intervention might avert stroke and its accompanying disability.

Obesity is an important factor for developing breast cancer in different countries. Obesity is one of the modifiable factors. The aim of the study was to find out the factors which might be associated with obesity among female breast cancer patients in Bangladesh. It was a case-control study conducted at the Department of Medical Oncology, National Institute of Cancer Research & Hospital (NICRH), Dhaka, Bangladesh from August 2014 to July 2015. Ninety one case and equal numbers of age matched controls were included in the study. The mean age of the case was 42.99 (±9.24) years and that of the control was 44.11±8.97 years. Majority of patients i.e. 59.3% (n=54) in case group was in pre-menopausal state where as 52.7% (n=48) of respondents in control group were in menopausal state. Increased waist to hip ratio (>0.85) was associated with increased risk of breast cancer (OR: 8.1). This was also true for increased BMI of ≥25kg/m² (OR: 4.57), increased waist circumference (OR: 3.52) and ever OCP use (OR: 2.11). However, para >3, education and moderate to heavy work were found to be protective against breast cancer (OR: <1). In clinical setting waist-to-hip ratio, body mass index (BMI) and waist circumference (WC) can be used effectively to identify women with an increased risk of breast cancer.

Abstract
Diabetic nephropathy (DN) is the leading cause of end-stage renal disease worldwide. Due to severe morbidity and mortality of DN and limited effective therapies, research has mainly focused on prevention of this debilitating illness by modification of risk factors. Aims of this study were to find out the prevalence of diabetic nephropathy, its factors and to correlate the functional status of the kidney. This cross-sectional study was conducted in the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from 1st January 2013 to 30th June 2013. A total 105 patients having clinical diagnosis of Diabetes mellitus were enrolled in this study. Data were collected by interview of the patients, clinical examination and laboratory investigation. Data was analyzed using the Chi-square test for Categorical variables and unpaired Student's 't' test for differences in means for continuous variables. P value <0.05 was considered significant. With DN (30.5%) patients 21.1% had micro-albuminuria and 9.5% had macro-albuminuria. The mean age for the DN patient was 47.9±14.7 years and male female ratio was 1:1. BMI was found significantly low in patients with DN (p<0.05). Prolonged duration of diabetes (>5 years) and uncontrolled diabetes were found as significant risk factors associated with DN. Other risk factors were hypertension, family history of hypertension, family history of diabetes mellitus and irregular treatment of diabetes mellitus. Mean serum creatinine, mean estimated glomerular filtration rate (GFR) and mean blood sugar level was 1.3±0.6mg/dl, 69.4±26.7ml and 15.6±7.1mmol/L respectively in DN patients. Relation was significant for higher serum creatinine and lower eGFR values (p<0.05). Prevalence of diabetic nephropathy was 30.5%. Long standing diabetes (>5 years) and uncontrolled diabetes were the important risk factors for the development of diabetic nephropathy. Diabetic nephropathy is associated with higher serum creatinine and lower eGFR values.

Abstract
Background Early diagnosis of breast cancer is essential for mitigating its related morbidity and mortality. Therefore, high awareness is required. Objectives We aimed to evaluate the knowledge, awareness and perceived barriers among females in Bangladesh regarding breast cancer. Methods A hospital-based survey was performed from April 2019 to June 2019. A total of 500 females aged >18 years were recruited to the study. The participants were selected by trained personnel and physicians via simple random sampling. Results The mean participant age was 37.13 ± 12.66 years. Among all the participants, 79% were married, 4% were single, 3% were divorced and 14% were widowed. We observed that 80.6% of respondents were housewives, 5% were students and 14.4% were working women. The participants had a severe lack of knowledge and awareness, and perceived barriers regarding breast cancer screening. Breast cancer was more linked to personal history, occupation and, marital status. Shyness, fear, lack of knowledge and deficient awareness programs were the major perceived barriers. Conclusion Educational interventions and proper, appropriate and socially acceptable awareness programs will help to ameliorate knowledge and awareness by addressing barriers regarding breast cancer among the females in Bangladesh.

Abstract
Rhinosporiodiosis is a chronic granulomatous infection of the mucus membranes caused by Rhino sporidium seeberi that manifest as vascular friable polyps and arise in the nasal mucosa. The mode of infection is probably trans-epithelial penetration. Rhinosporiodiosis is endemic in India, Pakistan and Srilanka. It occurs sporadically in the United States of America. The aim of this study was to compare betweenthe outcomes of endoscopic sinus surgery andsurgical excision in rhinosporiodiosis. The cross sectional comparative study was conducted among 40 patients with rhinosporiodiosis from January 2018 to April 2019 in the department of Otolaryngology and Head-neck surgery of Mymensingh Medical College Hospital, Bangladesh. All the patients were following up to 6 month after surgery. Most of them are male 24(60.0%) and female are 16(40.0%). Age of the patients in this study was (Mean±SD) 34.8±13.5 years. More than half of the patients had rhinosporiodiosis in the inferior turbinate (25, 62.5%) followed by 8(20.0%) in nasal septum and 7(17.5%) in the nasal floor. Endoscopic Sinus Surgery was done purposively among 20 patients and surgical excision was done purposively among another 20 patients. At the time of operation no complication occurs in case of endoscopic sinus surgery but in case of surgical excision small of amount bleeding was present. All the patients were followed up to 6 month after surgery. No recurrence was found in patients with endoscopic sinus surgery but 7(35.0%) patients who underwent surgical excision had recurrence of rhinosporiodiosis at follow up after six months of surgery. Chi-square test showed that the incidence of recurrence after 6 months of surgery was significantly lower in endoscopic sinus surgery (p=0.004). The study results concluded that endoscopic sinus surgery is better option for rhinosporiodiosis.

Abstract
Cutting and ligation of facial artery is the conventional practice for excision of submandibular gland. Facial artery is the main arterial supply to the lower face. Its preservation results in preservation of large proportion of vascularity to the lower face, preserves vascularity of platysma myocutaneous flap, allows repair of lower lip using Bernard's technique; facial artery is one of the most important recipient artery for microvascular free flap in modern reconstructive surgery in head and neck oncology. This prospective study was carried out in Department of Otolaryngology, Bangabandhu Sheikh Mujib Medical University Hospital (BSMMU), Dhaka, Bangladesh from October 2005 to October 2012 on 31 cases. Chronic submandibular sialoadenitis, benign submandibular gland tumours and cases of neck dissection where level I cervical lymph nodes were not involved by metastasis were included in this study. The facial artery was identified proximal to the gland and was dissected free from the gland by ligating or cauterizing its glandular branches to mobilize the gland. Appropriate anatomical aspects were noted and the time required for separation of the artery from the gland was recorded. Thirty-one consecutive cases were studied. The indications were chronic sialoadenitis (67.7%), pleomorphic adenoma (12.9%) and as a part of neck dissection for oncologic clearance of neck (19.4%). The mean duration of time for separation of the artery from the gland was 10.26 minutes. In two cases the facial artery could not be safely separated due to excessive adhesion from chronic inflammation. No significant complications were noted. Preservation of facial artery in submandibular gland excision is a simple procedure. So it should not be routinely sacrificed during this surgery.

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
The diurnal feeding patterns of dairy cows affects the 24 h robot utilisation of pasture-based automatic milking systems (AMS). A decline in robot utilisation between 2400 and 0600 h currently occurs in pasture-based AMS, as cow feeding activity is greatly reduced during this time. Here, we investigate the effect of a temporal variation in feed quality and quantity on cow feeding behaviour between 2400 and 0600 h as a potential tool to increase voluntary cow trafficking in an AMS at night. The day was allocated into four equal feeding periods (0600 to 1200, 1200 to 1800, 1800 to 2400 and 2400 to 0600 h). Lucerne hay cubes (CP = 19.1%, water soluble carbohydrate = 3.8%) and oat, ryegrass and clover hay cubes with 20% molasses (CP = 11.8%, water soluble carbohydrate = 10.7%) were offered as the 'standard' and 'preferred' (preference determined previously) feed types, respectively. The four treatments were (1) standard feed offered ad libitum (AL) throughout 24 h; (2) as per AL, with preferred feed replacing standard feed between 2400 and 0600 h (AL + P); (3) standard feed offered at a restricted rate, with quantity varying between each feeding period (20:10:30:60%, respectively) as a proportion of the (previously) measured daily ad libitum intake (VA); (4) as per VA, with preferred feed replacing standard feed between 2400 and 0600 h (VA + P). Eight non-lactating dairy cows were used in a 4 × 4 Latin square design. During each experimental period, treatment cows were fed for 7 days, including 3 days habituation and 4 days data collection. Total daily intake was approximately 8% greater (P < 0.001) for the AL and AL + P treatments (23.1 and 22.9 kg DM/cow) as compared with the VA and VA + P treatments (21.6 and 20.9 kg DM/cow). The AL + P and VA treatments had 21% and 90% greater (P < 0.001) dry matter intake (DMI) between 2400 and 0600 h, respectively, compared with the AL treatment. In contrast, the VA + P treatment had similar DMI to the VA treatment. Our experiment shows ability to increase cow feeding activity at night by varying feed type and quantity, though it is possible that a penalty to total DMI may occur using VA. Further research is required to determine if the implementation of variable feed allocation on pasture-based AMS farms is likely to improve milking robot utilisation by increasing cow feeding activity at night.
