Abstract
The objective of this study was to determine the potential effect and interaction of 3- nitrooxypropanol (3-NOP; Bovaer®) and whole cottonseed (WCS) on lactational performance, and enteric methane (CH4) emission of dairy cows. A total of 16 multiparous cows, including 8 Holstein Friesian (HF) and 8 Brown Swiss (BS) [224 ± 36 d in milk, 26 ± 3.7 kg milk yield], were used in a split-plot design, where the main plot was the breed of cows. Within each subplot, cows were randomly assigned to a treatment sequence in a replicated 4 × 4 Latin Square design with 2 × 2 factorial arrangements of treatments with 4, 24-d periods. The experimental treatments were: 1) Control (basal TMR), 2) 3-NOP (60 mg/kg TMR DM), 3) WCS (5% TMR DM), and 4) 3-NOP + WCS. The treatment diets were balanced for ether extract, crude protein, and NDF contents (4%, 16%, and 43% of TMR DM, respectively). The basal diets were fed twice daily at 0800 and 1800 h. Dry matter intake (DMI) and milk yield were measured daily, and enteric gas emissions were measured (using the GreenFeed system) during the last 3 d of each 24-d experimental period when animals were housed in tie stalls. There was no difference in DMI on treatment level, whereas the WCS treatment increased ECM yield and milk fat yield. There was no interaction of 3-NOP and WCS for any of the enteric gas emission parameters, but 3-NOP decreased CH4 production (g/d), CH4 yield (g/kg DMI), and CH4 intensity (g/kg ECM) by 13, 14 and 13%, respectively. Further, an unexpected interaction of breed by 3-NOP was observed for different enteric CH4 emission metrics: HF cows had a greater CH4 mitigation effect compared with BS cows for CH4 production (g/d; 18 vs. 8%), CH4 intensity (g/kg MY; 19% vs. 3%) and CH4 intensity (g/kg ECM; 19 vs. 4%). Hydrogen production was increased by 2.85 folds in HF and 1.53 folds in BS cows receiving 3-NOP. Further, there was a 3-NOP ' Time interaction for both breeds. In BS cows, 3-NOP tended to reduce CH4 production by 18% at around 4 h after morning feeding but no effect was observed at other time points. In HF cows, the greatest mitigation effect of 3-NOP (29.6%) was observed immediately after morning feeding and it persisted at around 23% to 26% for 10 h until the second feed provision, and 3 h thereafter, in the evening. In conclusion, supplementing 3-NOP at 60 mg/kg DM to a high fiber diet resulted in 18 to 19% reduction in enteric CH4 emission in Swiss Holstein Friesian cows. The lower response to 3-NOP by BS cows was unexpected and has not been observed in other studies. These results should be interpreted with caution due to low number of cows per breed. Lastly, supplementing WCS at 5% of DM improved ECM and milk fat yield but did not enhance CH4 inhibition effect of 3-NOP of dairy cows.

Abstract
Coronary artery bypass graft surgery (CABG) is a proven treatment for coronary artery disease. History of a ST-elevation myocardial infarction (STEMI) is considered an independent risk factor for CABG irrespective of timing for an emergency or elective surgery. Patients with STEMI are candidates for both On-pump and Off-pump CABG procedures. This paper discusses the possible best option for elective surgical revascularization in patients with prior STEMI. This prospective clinical trial of 60 eligible patients with prior STEMI was conducted in a Tertiary Care Hospital from April 2018 to March 2019. Among them, 30 patients underwent off-pump (Group A) and 30 patients underwent on-pump (Group B) CABG procedures. Outcomes between both groups were observed from surgery to 1 month postoperatively. Data was analysed by the software statistical program for social science (SPSS 25.0 Inc). The surgery was successful in both groups of patients. Differences were observed by mean number of grafts per patient (2.77±0.43 vs. 3.10±0.71) and duration of operation (4.41±0.35 hours vs. 5.71±0.48 hours). An improvement in Left Ventricular Ejection Fraction (LVEF %) was observed in both groups postoperatively (17.98% vs. 10.98%) and the postoperative LVEF% at different time points were found statistically significant (p<0.05) over preoperative LVEF%. Multivariable stepwise logistic regression analysis correlated on-pump CABG with prolonged need for ionotropic support, need for blood transfusion, longer hospital stay and less improvement in LVEF%. The study supports the Off-pump CABG as a better surgical option over on-pump CABG in patients with prior STEMI.

Exhalomics as a noninvasive method for assessing rumen fermentation in dairy cows: Can exhaled-breath metabolomics replace rumen sampling? J Dairy Sci 2024; 107:2099-2110. [PMID: 37949405 DOI: 10.3168/jds.2023-24124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 10/20/2023] [Indexed: 11/12/2023]
Abstract
Previously, we used secondary electrospray ionization-mass spectrometry (SESI-MS) to investigate the diurnal patterns and signal intensities of exhaled (EX) volatile fatty acids (VFA) of dairy cows. The current study aimed to validate the potential of an exhalomics approach for evaluating rumen fermentation. The experiment was conducted in a switchback design, with 3 periods of 9 d each, including 7 d for adaptation and 2 d for sampling. Four rumen-cannulated original Swiss Brown (Braunvieh) cows were randomly assigned to 1 of 2 diet sequences (ABA or BAB): (A) low starch (LS; 6.31% starch on a dry matter basis) and (B) high starch (HS; 16.2% starch on a dry matter basis). Feeding was once per day at 0830 h. Exhalome (with the GreenFeed System), and rumen samples were collected 8 times to represent every 3 h of a day, and EX-VFA and ruminal (RM)-VFA were analyzed using SESI-MS and HPLC, respectively. Furthermore, the VFA concentration in the gas phase (HR-VFA) was predicted based on RM-VFA and Henry's Law (HR) constants. No interactions were identified between the types of diets (HS vs. LS) and the measurement methods on daily average VFA profiles (RM vs. EX or HR vs. EX), suggesting a consistent performance among the methods. Additionally, when the 3-h interval VFA data from HS and LS diets were analyzed separately, no interactions were observed between methods and time of day, indicating that the relative daily pattern of VFA molar proportions was similar regardless of the VFA measurement method used. The results revealed that the levels of acetate sharply increased immediately after feeding, trailed by an increase in the acetate:propionate ratio and a steady increase for propionate (2 h after feeding the HS diet, 4 h for LS), and butyrate. This change was more pronounced for the HS diet than the LS diet. However, there was no overall diet effect on the VFA molar proportions, although the measurement methods affected the molar proportions. Furthermore, we observed a strong positive correlation between the levels of RM and EX acetate for both diets (HS: r = 0.84; LS: r = 0.85), RM and EX propionate (r = 0.74), and RM and EX acetate:propionate ratio (r = 0.80). Both EX-VFA and RM-VFA exhibited similar responses to feeding and dietary treatments, suggesting that EX-VFA could serve as a useful proxy for characterizing RM-VFA molar proportions to evaluate rumen fermentation. Similar relationships were observed between RM-VFA and HR-VFA. In conclusion, this study underscores the potential of exhalomics as a reliable approach for assessing rumen fermentation. Moving forward, research should further explore the depth of exhalomics in ruminant studies to provide a comprehensive insight into rumen fermentation metabolites, especially across diverse dietary conditions.

Exhaled volatile fatty acids, ruminal methane emission, and their diurnal patterns in lactating dairy cows. J Dairy Sci 2023; 106:6849-6859. [PMID: 37210352 DOI: 10.3168/jds.2023-23301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 04/08/2023] [Indexed: 05/22/2023]
Abstract
To date, the commonly used methods to assess rumen fermentation are invasive. Exhaled breath contains hundreds of volatile organic compounds (VOC) that can reflect animal physiological processes. In the present study, for the first time, we aimed to use a noninvasive metabolomics approach based on high-resolution mass spectrometry to identify rumen fermentation parameters in dairy cows. Enteric methane (CH4) production from 7 lactating cows was measured 8 times over 3 consecutive days using the GreenFeed system (C-Lock Technology Inc.). Simultaneously, exhalome samples were collected in Tedlar gas sampling bags and analyzed offline using a secondary electrospray ionization high-resolution mass spectrometry system. In total, 1,298 features were detected, among them targeted exhaled volatile fatty acids (eVFA; i.e., acetate, propionate, butyrate), which were putatively annotated using their exact mass-to-charge ratio. The intensity of eVFA, in particular acetate, increased immediately after feeding and followed a similar pattern to that observed for ruminal CH4 production. The average total eVFA concentration was 35.5 count per second (CPS), and among the individual eVFA, acetate had the greatest concentration, averaging 21.3 CPS, followed by propionate at 11.5 CPS, and butyrate at 2.67 CPS. Further, exhaled acetate was on average the most abundant of the individual eVFA at around 59.3%, followed by 32.5 and 7.9% of the total eVFA for propionate and butyrate, respectively. This corresponds well with the previously reported proportions of these VFA in the rumen. The diurnal patterns of ruminal CH4 emission and individual eVFA were characterized using a linear mixed model with cosine function fit. The model characterized similar diurnal patterns for eVFA and ruminal CH4 and H2 production. Regarding the diurnal patterns of eVFA, the phase (time of peak) of butyrate occurred first, followed by that of acetate and propionate. Importantly, the phase of total eVFA occurred around 1 h before that of ruminal CH4. This corresponds well with existing data on the relationship between rumen VFA production and CH4 formation. Results from the present study revealed a great potential to assess the rumen fermentation of dairy cows using exhaled metabolites as a noninvasive proxy for rumen VFA. Further validation, with comparisons to rumen fluid, and establishment of the proposed method are required.

Abstract
The objective of this study was to figure out the prevalence and probable causes of repeat breeding (RB) in dairy cows. Hence, a cross-sectional study was conducted on randomly selected 265 dairy farms in Sirajganj, Bogura, Rangpur, Satkhira, and Munshiganj districts of Bangladesh from December 2018 to February 2019. Data were collected through a direct interview method using a survey questionnaire. The reproductive organs of repeat breeder cows were examined for pathological, infectious, and functional reasons, and genital tract abnormalities. Additionally, the influence of nutrition, season, and age on the frequency of RB was recorded. The prevalence of RB was 28% among the 3824 cows investigated. Among the total repeat breeder cases, 72.54% of RB cases were found in Holstein-Friesian crossbred, 23.90% in Jersey crossbred, 1.50% in Sahiwal crossbred, and 2.06% in indigenous cows. The prevalence of RB was significantly highest (P < 0.01) in Satkhira (44.35%) and lowest in the Munshiganj district (15.87%). Data indicated that a major proportion of cows significantly (P < 0.05) faced RB problems due to functional causes (34.18%), followed by pathological causes (28.01%), genital tract abnormalities (21.32%), and infectious causes (16.49%). Furthermore, the cows were remarkably (P < 0.001) affected in RB during the summer season and nutritional deficient diseases like milk fever (70%). Age (3-7 years) had a significant (P < 0.001) effect on the RB occurrence (90%) in crossbred cows. However, particular focus should be given to systematic breeding, balanced nutrition, artificial inseminator efficiency, and hygienic inseminating tools to reduce RB incidence in high-yielding crossbred cows.

Abstract
Diverse risk factors intercede the outcomes of coronavirus disease 2019 (COVID-19). We conducted this retrospective cohort study with a cohort of 1016 COVID-19 patients diagnosed in May 2020 to identify the risk factors associated with morbidity and mortality outcomes. Data were collected by telephone-interview and reviewing records using a questionnaire and checklist. The study identified morbidity and mortality risk factors on the 28th day of the disease course. The majority of the patients were male (64.1%) and belonged to the age group 25-39 years (39.4%). Urban patients were higher in proportion than rural (69.3% vs. 30.7%). Major comorbidities included 35.0% diabetes mellitus (DM), 28.4% hypertension (HTN), 16.6% chronic obstructive pulmonary disease (COPD), and 7.8% coronary heart disease (CHD). The morbidity rate (not-cured) was 6.0%, and the mortality rate (non-survivor) was 2.5%. Morbidity risk factors included elderly (AOR = 2.56, 95% CI = 1.31-4.99), having comorbidity (AOR = 1.43, 95% CI = 0.83-2.47), and smokeless tobacco use (AOR = 2.17, 95% CI = 0.84-5.61). The morbidity risk was higher with COPD (RR = 2.68), chronic kidney disease (CKD) (RR = 3.33) and chronic liver disease (CLD) (RR = 3.99). Mortality risk factors included elderly (AOR = 7.56, 95% CI = 3.19-17.92), having comorbidity (AOR = 5.27, 95% CI = 1.88-14.79) and SLT use (AOR = 1.93, 95% CI = 0.50-7.46). The mortality risk was higher with COPD (RR = 7.30), DM (RR = 2.63), CHD (RR = 4.65), HTN (RR = 3.38), CKD (RR = 9.03), CLD (RR = 10.52) and malignant diseases (RR = 9.73). We must espouse programme interventions considering the morbidity and mortality risk factors to condense the aggressive outcomes of COVID-19.

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.

Global activation of oncogenic pathways underlies therapy resistance in diffuse midline glioma. Acta Neuropathol Commun 2020; 8:111.

Abstract
Diffuse midline gliomas (DMGs) are aggressive pediatric brain tumors with dismal prognosis due to therapy-resistant tumor growth and invasion. We performed the first integrated histologic/genomic/proteomic analysis of 21 foci from three pontine DMG cases with supratentorial dissemination. Histone H3.3-K27M was the driver mutation, usually at high variant allele fraction due to recurrent chromosome 1q copy number gain, in combination with germline variants in ATM, FANCM and MYCN genes. Both previously reported and novel recurrent copy number variations and somatic pathogenic mutations in chromatin remodeling, DNA damage response and PI3K/MAPK growth pathways were variably detected, either in multiple or isolated foci. Proteomic analysis showed global upregulation of histone H3, lack of H3-K27 trimethylation, and further impairment of polycomb repressive complex 2 by ASXL1 downregulation. Activation of oncogenic pathways resulted from combined upregulation of N-MYC, SOX2, p65/p50 NF-κB and STAT3 transcription factors, EGFR, FGFR2, PDGFRα/β receptor tyrosine kinases, and downregulation of PHLPP1/2, PTEN and p16/INK4A tumor suppressors. Upregulation of SMAD4, PAI-1, CD44, and c-SRC in multiple foci most likely contributed to invasiveness. This integrated comprehensive analysis revealed a complex spatiotemporal evolution in diffuse intrisic pontine glioma, recommending pontine and cerebellar biopsies for accurate populational genetic characterization, and delineated common signaling pathways and potential therapeutic targets. It also revealed an unsuspected activation of a multitude of oncogenic pathways, including cancer cell reprogramming, explaining the resistance of DMG to current therapies.

Abstract
As rice is an important staple food globally, research for development and enhancement of its nutritional value it is an imperative task. Identification of nutrient enriched rice germplasm and exploiting them for breeding programme is the easiest way to develop better quality rice. In this study, we analyzed 113 aromatic rice germplasm in order to identify quantitative trait loci (QTL) underpinning nutrition components and determined by measuring the normal frequency distribution for Fe, Zn, amylose, and protein content in those rice germplasm. Comparatively, the germplasm Radhuni pagal, Kalobakri, Thakurbhog (26.6 ppm) and Hatisail exhibited the highest mean values for Fe (16.9 ppm), Zn (34.1 ppm), amylose (26.6 ppm) and protein content (11.0 ppm), respectively. Moreover, a significant linear relationship (R2 = 0.693) was observed between Fe and Zn contents. Cluster analysis based on Mahalanobis D2 distances revealed four major clusters of 113 rice germplasm, with cluster III containing a maximum 37 germplasm and a maximum inter-cluster distance between clusters III and IV. The 45 polymorphic SSRs and four trait associations exhibited eight significant quantitative trait loci (QTL) located on eight different chromosomes using composite interval mapping (CIM). The highly significant QTL (variance 7.89%, LOD 2.02) for protein content (QTL.pro.1) was observed on chromosome 1 at 94.9cM position. Also, four QTLs for amylose content were observed with the highly significant QTL.amy.8 located on chromosome 8 exhibiting 7.2% variance with LOD 1.83. Only one QTL (QTL.Fe.9) for Fe content was located on chromosome 9 (LOD 1.24), and two (QTL.Zn.4 and QTL.Zn.5) for Zn on chromosome 4 (LOD 1.71) and 5 (LOD 1.18), respectively. Overall, germplasm from clusters III and IV might offer higher heterotic response with the identified QTLs playing a significant role in any rice biofortification breeding program and released with development of new varieties.

Abstract
The wastewater reuse for the purpose of irrigation may have a significant contribution to reduce water pollution, maximize water utilization and restore nutrient content of soils. An experiment was conducted at Environmental Science Field Laboratory, Bangladesh Agricultural University, Mymensingh from January to May, 2015 to investigate the effects of wastewater irrigation on soil physico-chemical properties (Soil texture, pH, electrical conductivity (EC), organic matter (OM), nitrogen (N), phosphorous (P), potassium (K), sulphur (S) and sodium (Na)) as well as yield and yield contributing characteristics of tomato crop. In this study, irrigation water, e.g., normal water, domestic wastewater, municipal wastewater and industrial wastewater was used as treatment with three replications. Soil and fruits were collected for analysis during last harvest. From the result, it is found that most of the chemical properties; OM, EC, N, K, S and Na contents were higher in wastewater treated soil compared to normal water irrigation. Among the treatments, plant height, LAI and yield were also higher in wastewater treated plot compared to normal water irrigated plot. Cost benefit analysis indicated that municipal wastewater irrigation gave more profit due to higher yield compared to domestic and industrial wastewater irrigation. From the study, it could be concluded that municipal wastewater irrigation was more profitable in respect of soil nutrient content and yield of tomato.

Abstract
The objective of the present study was to evaluate the effect of boiling duration on physicochemical, bioactive compounds, antioxidant activity, color, and texture properties of pumpkin (Cucurbita maxima). The pumpkin was subjected to boiling for 1, 5, 10, and 20 min at 100 ℃. The physicochemical analyses showed that pH, moisture, and water solubility index were increased, whereas ash content was decreased with increasing the boiling time. Prolong boiling exhibited a detrimental effect on bioactive compounds of pumpkin, and it was found that 20 min of boiling caused about 25.91% ± 2.21% loss of total phenolic content, 14.79% ± 1.03% loss of total carotenoids content, and 18.46% ± 1.34% loss of antioxidant activity. A kinetic study was conducted to quantify the losses occurring in bioactive compounds, antioxidant activity, changes in color, and firmness of pumpkin. The study revealed that the logistic model can predict the variation in bioactive compounds and antioxidant activity with higher R2. However, first-order kinetic models were found suitable to predict the changes occurring in bioactive compounds, antioxidant activity, color properties (L*, a*, b*, Chroma), and firmness. The total color changes (ΔE) showed a good fit with zero-order kinetic models (R2 = 0.98). The t1/2 and D-value were calculated for all measured parameters of pumpkin. These findings would be useful in designing thermal processes and related calculations of pumpkin.

Abstract
Acute myocardial infarction (AMI) patients constitute a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. A decrease in serum albumin concentration might be associated with an increased risk in the incident of both cardiovascular diseases and worse hospital outcome. We assessed whether serum albumin levels at admission was associated with in-hospital adverse outcome in patients with first attack of acute myocardial infarction (AMI). The aim of the study was to evaluate association of serum albumin level with in-hospital outcome in patients with first attack of acute myocardial infarction. This cross-sectional analytical study was conducted in the department of cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2017 to February 2018. Total 374 patients of first attack of acute myocardial infarction included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I (Patients with acute myocardial infarction with serum albumin <3.5gm/dl) and. Group II (Patients with acute myocardial infarction with serum albumin ≥3.5gm/dl). Serum albumin level was measured within 24 hours of admission and the incidence of in-hospital major cardiac outcomes was observed. In this study mean±SD serum albumin level of Group I, Group II were 3.02±0.12gm/dl, 4.48±0.50gm/dl respectively. In Group I patient, 52(59.80%), 7(8.00%), 10(11.50%), developed heart failure, cardiogenic shock, arrhythmias respectively and 8(9.20%) died and in Group II patient 20(7.90%), 7(2.80%), 8(3.20%) developed heart failure, cardiogenic shock, arrhythmias respectively and 4(1.60%) died out of them and all of these outcome were statistically significant. Mean±SD duration of hospital stay of the study population according serum albumin level, in Group I, 5.76±1.83 days, in Group II, 4.40±1.22 days which was statistically significant (p<0.05). In conclusion, patient with first attack of acute myocardial infarction serum albumin level below 3.50gm/dl increased the risk of worse in-hospital outcome.

Abstract
While the pleasant scent of aromatic rice is making it more popular, with demand for aromatic rice expected to rise in future, varieties of this have low yield potential. Genetic diversity and population structure of aromatic germplasm provide valuable information for yield improvement which has potential market value and farm profit. Here, we show diversity and population structure of 113 rice germplasm based on phenotypic and genotypic traits. Phenotypic traits showed that considerable variation existed across the germplasm. Based on Shannon-Weaver index, the most variable phenotypic trait was lemma-palea color. Detecting 140 alleles, 11 were unique and suitable as a germplasm diagnostic tool. Phylogenetic cluster analysis using genotypic traits classified germplasm into three major groups. Moreover, model-based population structure analysis divided all germplasm into three groups, confirmed by principal component and neighbors joining tree analyses. An analysis of molecular variance (AMOVA) and pairwise FST test showed significant differentiation among all population pairs, ranging from 0.023 to 0.068, suggesting that all three groups differed. Significant correlation coefficient was detected between phenotypic and genotypic traits which could be valuable to select further improvement of germplasm. Findings from this study have the potential for future use in aromatic rice molecular breeding programs.

Abstract
Pediatric myocardium is unique from mature myocardium; thus, the use of adult cardioplegia for pediatric cardiac operations may provide suboptimal myocardial protection. It is found that children undergoing heart surgery show evidence of less myocardial damage when del Nido cardioplegia is used instead of a standard cardioplegic solution. Del Nido cardioplegia solution provides a depolarized hyperkalaemic arrest lasting up to 60 minutes, reduces spontaneous and inducible activity during arrest, and prevents hyper contraction during early reperfusion. In this single blind randomized trial, a total of 60 patients underwent intra cardiac repair for TOF in National Institute of Cardiovascular Diseases, Dhaka, Bangladesh from July 2014 to January 2016 fulfilling inclusion and exclusion criteria. They were randomly assigned in two groups- 30 patients in Del Nido group (Group A) and 30 patients in standard group (Group B). Comparison between groups was done by Chi square test and Student's test. All data were analyzed by SPSS 20.0 for windows. P value less than 0.05 was considered as significant. There was statistically significant difference among the patients in terms of mean total initial cardioplegia volume, mean number of additional dose, mean additional dose amount, mean cross clamp time, mean CPB time (331.67±188.07 vs. 458.67±226.62, p=0.022; 0.13±0.35 vs. 1.27±0.89, p=0.000; 23.33±60.76 vs. 336.83±259.6, p=0.000; 45.10±10.35 vs. 59.23±23.21, p=0.003; 89.30±15.73 vs. 111.10±29.23, p=0.001 respectively). Mean post operative serum troponin I level at arrival in ICU and after 24 hours between two groups were statistically significantly different (55.60±32.91 vs. 83.5±58.99; p=0.024 and 13.01±5.84 vs. 18.16±9.51; p=0.014 respectively). The mean ventilation duration, mean ICU stay were also statistically significant. This study showed that cardiac arrest with Del Nido cardioplegia during intra cardiac repair for TOF was associated with improved myocardial protection over standard cardioplegia in terms of reduced CPB and cross clamp times, lower total volume of cardioplegia.

Abstract
Incidence of coronary artery disease (CAD) is increasing in developing countries in Bangladesh with improvement of socioeconomic status, urbanization, changes of dietary habits and lifestyle. Dyslipidaemia is one of the major contributors increase CAD risk. This study was aimed to find out the association of low level HDL-C with acute coronary syndrome. This cross sectional study was conducted in the department of cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August 2009 to May 2010. Sociodemographic characteristics, smoking, hypertension, FBS, serum total cholesterol level, HDL-C, LDL-C, Triglyceride level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) Group I and 50 healthy people (control) Group II. Investigations included ECG, Troponin-I, FBS and Fasting Lipid Profile. The data was analyzed by computer with the help of SPSS. Chi-square test, T-test, ANOVA test used as test of significance. The mean level in cases of HDL-C 39.3±5.1 and in control level HDL-C 34.2±3.4 statistically significant (p<0.0001). In both group low concentration HDL-C (<40mg/dl) risk for CAD. Un-adjusted odds ratio 95% CI determinants of ACS, HDL-C of OR was 0.2. So, HDL-C is not protective factor. In multivariate logistic regression analysis that adjusted for confounders of HDL-C level (age, sex, smoking, hypertension, TC, LDL-C, TG) associated with ACS. HDL-C was strong predictor of ACS (RR in the highest) compared with lowest quarantile = 0.02; (95% CI=0.003-0.173; P for trend <0.0001). The study reflected that low HDL-C level associated with ACS. Categorization of patients with ACS on the basis HDL-C level may be helpful for risk stratification and management.

Abstract
While the functionality and healthy food value of red rice have increased its popularity, such that market demand for it is expected to rise, most strains suffer from low grain yield. To perform diversity and population structure analyses of red rice germplasm, therefore, becomes essential for improving yields for commercial production. In this study, fifty red rice germplasm from the Bangladesh Rice Research Institute (BRRI) genebank were characterized both morphologically and genetically using fifty simple sequence repeat (SSR) markers. Overall, 162 alleles were detected by the markers with the detected allele number varying from two to seven. Additionally, 22 unique alleles were identified for use as a germplasm diagnostic tool. The highest and lowest polymorphic information content (PIC) indices were 0.75 and 0.04 found in markers RM282 and RM304, respectively, and genetic diversity was moderate, varying from 0.05 to 0.78 (average: 0.35). While phylogenetic cluster analysis of the fifteen distance-based agro-morphological traits divided the germplasm into five clusters (I, II, III, IV and V), a similar SSR analysis yielded only three major groups (I, II, and III), and a model-based population structure analysis yielded four (A, B, C and D). Both principal component and neighbors joining tree analysis from the population structure method showed the tested germplasm as highly diverse in structure. Moreover, an analysis of molecular variance (AMOVA), as well as a pairwise FST analysis, both indicated significant differentiation (ranging from 0.108 to 0.207) among all pairs of populations, suggesting that all four population structure groups differed significantly. Populations A and D were the most differentiated from each other by FST. Findings from this study suggest that the diverse germplasm and polymorphic trait-linked SSR markers of red rice are suitable for the detection of economically desirable trait loci/genes for use in future molecular breeding programs.

Abstract
Coronary heart disease (CHD) is the most common cause of heart disease and is the single most important cause of premature death in developed world. Recognizing a patient with ACS is important because the diagnosis triggers both triage and management. cTnI is 100% tissue-specific for the myocardium and it has been shown to be a very sensitive and specific marker for acute myocardial infarction (AMI). Ventricular function is the best predictor of death after an acute coronary syndrome. It serves as a marker of myocardial damage, provides information on systolic function as well as diagnosis and prognosis. The study aimed at investigating the impact of elevated Troponin-I level on LV ejection fraction and in-hospital outcomes in patients with first attack of Non ST-segment Elevation Myocardial Infarction (NSTEMI). This prospective analytical study was conducted in the Department of Cardiology in Mymensingh Medical College Hospital from December 2015 to November 2016. Total 130 first attack of NSTEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I - Patients with first attack of NSTEMI with good LV function (LVEF: ≥55%). Group II - Patients with first attack of NSTEMI with LV systolic dysfunction (LVEF: <55%). Then Troponin-I and LVEF levels were correlated using Pearson's correlation coefficient test. In this study mean Troponin-I of Group I and Group II were 5.53±7.43 and 16.46±15.79ng/ml respectively. It was statistically significant (p<0.05). Echocardiography showed that patients with high Troponin-I level had low ejection fraction (LVEF) and patients with low Troponin-I level had preserved ejection fraction (LVEF). Analysis showed that patients with severe left ventricular systolic dysfunction (LVEF <35%) had the highest level of Troponin-I with worse in-hospital outcomes and vice versa-the patients with the preserved systolic function (LVEF ≥55%) had the lowest levels of Troponin-I with better in-hospital outcomes. In our study, it also showed that the levels of Troponin-I had negative correlation with LV ejection fraction levels, with medium strength of association (r= -0.5394, p=0.001). The study enabled us to conclude that, the higher was the Troponin-I level, the lower was the LV ejection fraction level and thus worse in-hospital outcomes in first attack of NSTEMI patients.

Abstract
Anterior cruciate ligament (ACL) is the most commonly injured ligament occurs in young adult population, which markedly reduces activity level. Anterior cruciate ligament rupture is a threat to the homeostasis of the knee. So, reconstruction of the ACL is necessary to make them fit and return to their pre-injury activity level. The choice of graft for ACL reconstruction is a matter of debate, with the BPTB graft and quadruple graft of ST-G being the two most popular options. Use of triplet graft of semi-tendinosus tendon alone without sacrificing gracilis is another option. So hypothesis was Arthroscopic ACL reconstruction with triplet autograft of semi-tendinosus tendon alone is an effective procedure. This prospective interventional study was conducted from October 2011 to March 2013 at Dhaka Medical College Hospital, Dhaka, Bangladesh. Fourteen patients who had a unilateral anterior cruciate ligament rupture underwent arthroscopic reconstruction with triplet graft of semi-tendinosus tendon. Accelerated ACL reconstruction rehabilitation protocol was followed and final outcome evaluation done at 24 weeks according to IKDC knee examination form and Lysholm knee scoring scale. Preoperative Lysholm knee score was 52.64 and postoperative score was 90, that shows significant improvement (p<0.05). According to Lysholm knee scoring scale, excellent results (95-100 points) were obtained in 33% patients, good results (85-94 points) in 53% patients, fair and poor (7% each). For arthroscopic ACL reconstruction, choice of semi-tendinosus tendon alone preserving gracilis, comparable outcome as with BPTB/ST-G graft, can be achieved, minimizing the hamstring strength deficit. Moreover gracilis being reserved for future use in revision ACL reconstruction and/or in other reconstructive surgery.

Abstract
The traditional lipidic parameters when present and clusters within reference range, often fails to predict the risk of acute coronary syndrome in young population in this region. Measurement of Apolipoprotein B (Apo B), a parameter of the lipoprotein-lipid profile, provides a method of quantifying the concentration of lipoproteins, rather than their cholesterol content. Present study aimed to quantify the risk of acute coronary syndrome (ACS) in young people with having none to less number of traditional lipidic parameters for dyslipidemia. This is a case control study among 50 cases of first attack of ACS among 18-45 years of age of both sexes, admitted in coronary care unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from June 2009 to May 2010. Data was recently reanalyzed. Out of five sub-sets of lipid profile, namely TC, TG, HDL-C, LDL-C and non-HDL-C, 16(32%) cases were dyslipidemic by 0 (none) parameter, 13(26%) cases by one parameter, 7(14%) cases by two parameters, 4(8%) cases by three cases, 7(14%) cases by four parameters and 3(6%) cases by all five parameters. It was found that none to lesser the number of dyslipidemic parameters, greater the percentage of ACS cases and they are having hyper ApoB with statistically significant association (p<0.05).

Abstract
This cross-sectional analytical study was conducted in Cardiology & Medicine Department of Mymensingh Medical College Hospital. After fulfilling the exclusion & inclusion criteria, B-type natriuretic peptide concentrations were measured in a convenience sample of 100 predominantly male (94%) dyspnic patients who got admitted in Cardiology & Medicine Department of Mymensingh Medical College & Hospital from November 2013 to October 2014. The diagnosis of Congestive Heart Failure (CHF) was based on generally accepted Framingham criteria with corroborative information including hospital course (response to diuretics, vasodilators, inotropes or hemodynamic monitoring) and results of further cardiac testing, including echocardiography. Patients with right heart failure from cor pulmonale were classified as having CHF. Pulmonary disease was confirmed by using the following diagnostic tools: i) A chest X-ray without signs of heart enlargement or pulmonary venous hypertension or a chest X-ray with signs of chronic obstructive lung disease, ii) Normal heart function as seen by echocardiography, iii) Abnormal pulmonary function tests or follow-up results and iv) A positive response to treatment with steroids, nebulizers or antibiotics in hospital. Patients with CHF (n=50) had mean BNP level 1146.72pg/ml (range 103 to 5000pg/ml), which is significantly higher than the group of patients with a final diagnosis of pulmonary disease (n=50) whose BNP was 34pg/ml (range 10 to 90pg/ml) (p<0.05). In conclusion, it was found that B-type natriuretic peptide is an important biomarker for differentiating congestive heart failure from lung disease in patients presenting with dyspnea.

Abstract
Coronary Angiogram (CAG) has been used to detect coronary artery disease in myocardial infarction (both STEMI and NSTEMI) patients. The purpose of this study was to compare the degree of coronary artery disease among STEMI and NSTEMI patients. Among acute coronary syndrome in NSTEMI we found more widespread coronary artery disease other than STEMI. Lack of documentations encouraged us to perform this study in our center. In this retrospective observational study we summarized all myocardial infarction (MI) patients who underwent coronary angiography (CAG) from August 2013 to August 2014 at Enam Medical College Hospital, Dhaka, Bangladesh and data of degree of coronary artery disease were recorded. Data of 100 consecutive MI patients who underwent CAG during that period were recorded. Among them 50 patients having STEMI as Group I (male 45, female 5) & other 50 patients sustained NSTEMI as Group II (male 38, female 12). Among NSTEMI patient group 80% were having multi-vessel disease and in STEMI patient group 80% having single vessel disease and remaining having multi-vessel disease. The degree of coronary artery disease is extensive in NSTEMI patients than in STEMI group. Coronary angiogram can visualize the degree of coronary artery involvement and is a useful screening modality to compare disease extent in MI patients.

Abstract
Bangladesh has been considered as one of the five countries endemic with highly pathogenic avian influenza A subtype H5N1 (HPAI H5N1). Live-bird markets (LBMs) in south Asian countries are believed to play important roles in the transmission of HPAI H5N1 and others due to its central location as a hub of the poultry trading. Food and Agriculture Organization (FAO) of the United Nations has been promoting improved biosecurity in LBMs in Bangladesh. In 2012, by enrolling 32 large LBMs: 10 with FAO interventions and 22 without assistance, we assessed the virus circulation in the selected LBMs by applying standard procedures to investigate market floors, poultry stall floors, poultry-holding cases and slaughter areas and the overall biosecurity using a questionnaire-based survey. Relative risk (RR) was examined to compare the prevalence of HPAI H5N1 in the intervened and non-intervened LBMs. The measures practised in significantly more of the FAO-intervened LBMs included keeping of slaughter remnants in a closed container; decontamination of poultry vehicles at market place; prevention of crows' access to LBM, market/floor cleaning by market committee; wet cleaning; disinfection of floor/poultry stall after cleaning; and good supply of clean water at market (P < 0.05). Conversely, disposal of slaughter remnants elsewhere at market and dry cleaning were in operation in more of the FAO non-intervened LBMs (P < 0.05). The RR for HPAI H5N1 in the intervened and non-intervened LBMs was 1.1 (95% confidence interval 0.44-2.76), suggesting that the proportion positive of the virus in the two kinds of LBM did not vary significantly (P = 0.413). These observations suggest that the viruses are still maintained at the level of production in farms and circulating in LBMs in Bangladesh regardless of interventions, albeit at lower levels than in other endemic countries.

Abstract
There is a relationship between the left ventricular diastolic dysfunction with uncontrolled diabetes mellitus. A cross sectional study was designed to see the association of uncontrolled diabetes mellitus with diastolic dysfunction of the heart. The study was conducted from April 2012 to March 2013 in the department of cardiology, Mymensingh Medical College Hospital, Mymensingh. Sixty cases were selected as study population; twenty one patients were in Group I with good glycaemic controlled of HbA1C <7% and 39 patients were in Group II with poorly controlled diabetes mellitus having HbA1C ≥ 7%. In the study population male were 43(71.70%) and female were 17(28.30%). Mean age in the two groups were 49.05 ± 6.34 years vs. 53.64 ± 5.38 years, which was not significant difference. Duration of diabetes was <10 years and ≥ 10 years in two groups. Glycaemic status (percentage of HbA1C) was 6.55 ± 0.29% vs. 8.72 ± 1.01% in controlled and uncontrolled diabetic patient groups respectively which was significant difference. Diastolic dysfunction was found more in uncontrolled diabetic patient (patients having HbA1C% ≥ 7%) than controlled diabetic patients (HbA1C <7%). Grade I diastolic dysfunction was in uncontrolled and controlled glycaemic status were 33(84.60%) and 04(19.00%). The difference was statistically significant. Diastolic dysfunction in type 2 diabetic subjects was significantly higher as compared to the well control group (p<0.001). And this study concluded as - Diastolic dysfunction is more common in patient with poorly controlled diabetes mellitus.

Abstract
The purpose of this study is to measure apolipoprotein B (ApoB) in hyper-triglyceridemic (HTG) young people of Bangladesh for predicting risk of acute coronary syndrome. This case-control study was carried out in Department of Cardiology, of Mymensingh Medical College Hospital within the period from June 2009 to May 2010. A total 50 case of 18-45 years of age with first attack of acute coronary syndrome admitted in coronary care unit and 50 healthy controls of same age and sex distribution were studied. Twenty (40%) of the studied case and 21(42%) of controls had hyper hyper-triglyceridemia, of those 18(90%) of HTG cases and 12(57.1%) of HTG controls had hyper-ApoB condition. The present study shows significant association of apolipoprotein B as an independent determinant and estimation of ApoB may be an alternative tool for predicting risk of development of acute coronary syndrome in hyper-triglyceridemic young people.

Abstract
Neu-Laxova syndrome (NLS) is a rare lethal syndrome found in both consanguinous and non-consanguinous couple. This is characterized by terrible face with unusual craniofacial appearance with exophthalmos, spectrum of central nervous system malformation, like microcaphaly, hypoplastic cerebellum, cleft lip/palate, ichthyosis and oedema. The diagnosis is made on the basis of clinical parameter. We report a 4 hour old male term newborn with IUGR of Neu-Laxova syndrome presented with anencephaly, rudimentary cerebellum, exophthalmos of right eye, bilateral cleft lip and palate and cryptorchidism. Anencephaly and cryptorchidism are two recently reported findings of NLS. We are presenting this case in addition from Bangladesh to lend further support to those two new findings as component of Neu-Laxova syndrome. Outcome of this syndrome is not good. Most of the patients are died of infection within hours to days.

Abstract
This case control study was carried out in Mymensingh Medical College Hospital, Mymensingh, Bangladesh and Dhaka Medical College Hospital, Dhaka, Bangladesh from November 2010 to October 2011 to find out the risk factors of non-alcoholic fatty liver disease. A total of 90 participants (45 cases and 45 controls) were included. A higher proportion of patients with age >45 years were found in case group compared to control (51.1% vs. 15.6%). The mean age was significantly higher in case group 49.8±12.6 years. Males demonstrated their predominance in both case (62.2%) and control (68.9%) groups, although the two groups did not differ in terms of sex distribution. Body mass index demonstrates that 26.7% of patients in case group were of normal weight, 46.7% overweight and 26.7% obese. In the control group, two-thirds (68.9%) of the patients were of normal weight and 24.4% overweight and 7.8% obese. Diabetes and hypertension were significantly present in the case group than those in control counterparts 75.6% vs. 15.6% and 86.7% vs. 15.6 % respectively. The mean fasting blood glucose, ALT, total cholesterol and triglycerides were significantly higher in case group compared to control group 7.8±1.3 vs. 5.4±2.5mmol/L (p<0.001); 39.1±12.4 vs. 30.3±14.1IU/L, (p=0.002); 239.9±14.3 vs. 183.3±11.4mg/dl, (p<0.001) and 183.6±12.5 vs. 133.5±16.0mg/dl, (p<0.001) respectively. However, no significant difference was observed between the case and the control groups in terms of HDL cholesterol (35.9±1.2 vs. 38.0±1.1mg/dl, p=0.203). Majority of the patients in case group (88.9%) exhibited increased echogenicity of liver on ultrasonogram as opposed to 15.6% in the control group.

Abstract
The study was aimed to find out the impact of metabolic syndrome in patients with acute myocardial infarction during hospital stay. This prospective study was carried out in coronary care unit, Mymensingh Medical College Hospital from August 2009 to May 2010. Patients were followed up for minimum 3 days to maximum 6 days after admission. Variables of this study were age, sex, smoking, anterior AMI, inferior AMI, Non STEMI, hyperglycemia, low high density lipoprotein (HDL), raised blood pressure, high triglyceride (TG), waist circumference, recurrent non fatal MI, heart failure (Killip class), arrhythmia (VT, VF), ejection fraction (EF), family history of cardiovascular (CV) risk factors. Considering inclusion and exclusion criteria total 100 patients were included and divided into two groups, Group A - Acute Myocardial Infarction (AMI) with Metabolic Syndrome (MS) and Group B - Acute Myocardial Infarction (AMI) without Metabolic Syndrome (MS). Investigations included ECG, FBS, fasting lipid profile, cardiac enzyme (troponin I) and echocardiography (2D & M mode). The data were analyzed by computer software SPSS version 12. Chi-square test, t test, ANOVA test was used as test of significance. Among the study population (n=100), female were 12.0%. Mean age of study population was 53.3±10.6 years vs. 47.5±11.3 years. Distribution of metabolic syndrome components in study population, High TG (?150mg/dl) was more prevalent (81.1% vs. 25.8%). Heart failure (Killip class) was significantly more in metabolic syndrome patients than those without metabolic syndrome (46.0 % vs. 20%). LV ejection fraction also lowers in metabolic syndrome patients (46.76±8.34 vs. 50.45±7.50) with MI. Among the components of metabolic syndrome, hyperglycemia had strongest association for development of heart failure (OR 3.05; 95% CI 0.80-12.14).

Abstract
Patients presented with the supraclavicular lymphadenopathy in the medicine department have a strong suspicion of serious illness like tuberculosis, sarcoidosis, toxoplasmosis and malignancy of lymphnode, blood, lung, upper GIT, breast, ovary, testes, and other sites of body. This prospective type of observational study carried out in the indoor and out patient department of medicine of Mymensingh Medical College Hospital over a period of 6 month from April 2011 to September 2011 to diagnose the causes of supraclavicular lymphadenopathy. Patient of either sex, 18 years or above presented with supraclavicular lymphadenopathy were included. Biopsy or FNAC were done. The study showed that mean age of the patient of supraclavicular lymphadenopathy that finally diagnosed as malignant was 49.7 years and that of non malignant was 33.7 years. Male patient have suffered more (60%) from malignant disease than that of female patient (40%). Discrete, hard, non tender either fixed or non fixed supraclavicular lymphadenopathy was found malignant (18 of 18 cases, 100%) and discrete, firm, tender lymphnode were found non malignant (5 of 5 cases, 100%). Increased frequency (11 of 28, 39.3%) of granulomatous inflammation from the tuberculoid lymphadenitis were found among the patient undergone supraclavicular lymphnode biopsy. FNAC result was also of simillar type and finally it was found that frequency of tuberculosis (20 of 53, 37.7%) was highest and bronchial carcima was the second most frequent diagnosis (14 of 53, 26.4%). This study showed that supraclavicular lymphadenopathy is associated mostly with serious disease like tuberculosis and malignancy.

Abstract
The consumer demand is increasing for composite flour based bakery products like biscuits. The incorporation of brown rice flour can be justified in composite flour based biscuits as it has beneficial nutraceutical properties and its gluten-free nature can play important role in preventing celiac problem. The physicochemical and functional properties of brown rice and wheat flour were studied and biscuits were prepared with the incorporation of brown rice flour in 0, 5, 10, 15 and 20 % with the wheat flour to assess the quality and acceptability of the biscuits. The water absorption capacity of brown rice flour was lower than that of wheat flour (p?0.05), whereas oil absorption and foaming capacity of brown rice flour were significantly higher than that of wheat flour (p ?0.05). The brown rice flour had higher least gelation concentration (30.66%) as compared with wheat flour (20.33%). As the concentration of brown rice flour was increased, spread ratio of biscuits decreased. The biscuits containing 5, 10 and 15% brown rice flour indicated that addition of increasing level of brown rice flour had higher ash, fat, moisture and crude fiber contents, while protein and total carbohydrate contents found lower in the biscuits. Statistical analysis of biscuits containing various amount of brown rice flour (0, 5, 10, 15 and 20% brown rice flour) showed that control biscuits (0% brown rice flour) secured the highest score for color, flavor, texture and overall acceptability, which is followed by biscuits containing 10, 5,15 and 20% brown rice flour.

Abstract
The aim of this study was to detect arsenic concentrations in feed, well-water for drinking, eggs, and excreta of laying hens in arsenic-prone areas of Bangladesh and to assess the effect of arsenic-containing feed and well-water on the accumulation of arsenic in eggs and excreta of the same subject. One egg from each laying hen (n = 248) and its excreta, feed, and well-water for drinking were collected. Total arsenic concentrations were determined by atomic absorption spectrophotometer, coupled with hydride generator. Effects of arsenic-containing feed and drinking-water on the accumulation of arsenic in eggs and excreta were analyzed by multivariate regression model, using Stata software. Mean arsenic concentrations in drinking-water, feed (dry weight [DW]), egg (wet weight [WW]), and excreta (DW) of hens were 77.3, 176.6, 19.2, and 1,439.9 ppb respectively. Significant (p < 0.01) positive correlations were found between the arsenic contents in eggs and drinking-water (r = 0.602), drinking-water and excreta (r = 0.716), feed and excreta (r = 0.402) as well as between the arsenic content in eggs and the age of the layer (r = 0.243). On an average, 55% and 82% of the total variation in arsenic contents of eggs and excreta respectively could be attributed to the variation in the geographic area, age, feed type, and arsenic contents of drinking-water and feed. For each week's increase in age of hens, arsenic content in eggs increased by 0.94%. For every 1% elevation of arsenic in drinking-water, arsenic in eggs and excreta increased by 0.41% and 0.44% respectively whereas for a 1% rise of arsenic in feed, arsenic in eggs and excreta increased by 0.40% and 0.52% respectively. These results provide evidence that, although high arsenic level prevails in well-water for drinking in Bangladesh, the arsenic shows low biological transmission capability from body to eggs and, thus, the value was below the maximum tolerable limit for humans. However, arsenic in drinking-water and/or feed makes a significant contribution to the arsenic accumulations in eggs and excreta of laying hens.

Abstract
This research was carried out to determine the prevalence of subclinical mastitis in lactating Dairy Cow of Bangladesh Agricultural University dairy farm (BAUDF) and rural areas of Tangail sadar upazila of Bangladesh during the period of July 2009 to April 2010. A total of 200 milk samples (40 from BAUDF and 160 from Tangail sadar upazila) were collected for this study which were subjected to physical examination and subsequently screened for subclinical mastitis using three indirect tests viz. White Side Test (WST), California Mastitis Test (CMT), and Surf Field Mastitis Test (SFMT). Overall prevalence of subclinical mastitis (SCM) in lactating dairy cows found in this study was 29%. Cows were infected with SCM 29.5%, 27.5% and 25.5% detection by CMT, WST and SFMT respectively. Higher prevalence of SCM was detected in milch crossbred cows (36.36%) in comparison to local bred cows (24.61%) maintained under extensive management system in Rural area of Tangail sadar upazila. The prevalence of SCM was recorded in 31.58%, 30.76% and 68.75% in cows of local area of Tangail sadar upazila, and 25.0%, 40.0% and 71.42% in cows of BAU,DF during the early, mid and late stages of lactation respectively. The highest prevalence of SCM was recorded during the early lactation stage in both the local breed cows (30.0%) and cows of BAUDF (45.83%) in comparison to their respective mid and late stages of lactation. The prevalence of SCM was highest in lactating cows having third lactation and high yielding (cows produced >10 liter milk per day) both in local breed and crossbred cows.DOI = http://dx.doi.org/10.3329/bjvm.v9i1.11216 Bangl.

Abstract
This study was done to see the efficacy and tolerability of methotrexate and hydroxychloroquine in the Treatment of Rheumatoid Arthritis. It was an open label controlled clinical trial, done in Mymensingh Medical college hospital. Fifty six patients were selected by random sampling method, 28 were included in methotrexate group and another 28 for hydroxychloroquine group using inclusion & exclusion criteria. Primary efficacy variables (DAS28, daily naproxen), secondary efficacy variables, and safety measurement variables studied both clinically & laboratory investigations. The data were analyzed by computer with the help of SPSS. The student's t test was used as test of significant. The mean age of the patients at diagnosis was almost identically distributed between methotrexate and hydroxychloroquine group (41.7±12.2 vs. 42.9±9.2 years, p=0.659). Disease activity at baseline was found to be almost homogeneous to each group except CRP which was observed to be significantly higher in methotrexate group than hydroxychloroquine group (p<0.001). Disease activity at 1 month of treatment reduced in the methotrexate group than those in hydroxychloroquine group (p<0.05 in each case). After 3 and 6 months of treatment, disease activity decreased significantly in both groups (p<0.001 and p<0.05 respectively). The average daily dose of NSAID (Naproxen) decreased significantly (p<0.001). Safety variables at 6 month were within normal physiological ranges and did not differ in groups (p>0.05) indicating that both methotrexate and hydroxychloroquine were effective and safe to use in rheumatoid arthritis. The difference in the incidence of adverse effects, total or individual, was almost nil.

Abstract
The aim of the present study was to clarify the responsiveness of the chicken basilar artery to 5-hydroxytryptamine (5-HT) and acetylcholine (ACh) and to characterize the related receptor subtypes in vitro. Basilar arteries were obtained from freshly slaughtered broiler chickens. The 5-HT induced concentration-dependent contraction of the arteries. The concentration-response curves for 5-HT were shifted 30-fold to the right by methiothepin (a 5-HT(1) and 5-HT(2) receptor antagonist) and 3-fold to the right by ketanserin (a 5-HT(2) receptor antagonist). In the presence of ketanserin, the concentration-response curve for 5-HT was shifted 10-fold to the right by methiothepin. The pA(2) value for methiothepin was 8.26. The ACh induced concentration-dependent relaxation under conditions of precontraction by 5-HT. The concentration-response curve for ACh was shifted to the right by atropine [a nonselective muscarinic (M) receptor antagonist] and hexahydro-sila-difenidol hydrochloride, a p-fluoroanalog (pFHHSiD, an M(3) receptor antagonist), but not by pirenzepine (an M(1) receptor antagonist) or methoctramine (an M(2) receptor antagonist). The pA(2) value for pFHHSiD was 7.55. Nω-Nitro-l-arginine (a nitric oxide synthase inhibitor) inhibited ACh-induced relaxation by approximately 50%. These results suggest that 5-HT induces contraction via activation of 5-HT(1) and 5-HT(2) receptors and that ACh induces relaxation via activation of the M(3) receptor. The 5-HT(1) receptor might play a dominant role in 5-HT-induced contraction. One of the factors involved in ACh-induced relaxation is probably nitric oxide released from endothelial cells.

Abstract
Although human milk is generally accepted as the gold standard for the feeding of term infants, its use in the preterm and very low birth weight (VLBW) infants particularly in the initial period of birth has been more controversial. Little is known about the risks and benefits of early introduction of breast feeding on preterm VLBW infants. The primary object of this study was to evaluate the safety and benefit of early breast milk feeding in preterm VLBW newborns during their initial hospitalization periods. Therefore a prospective observational study was conducted among 37 preterm VLBW infants who were admitted to the Neonatal ward of Sir Salimullah Medical College and Mitford Hospital during the period of February 15th to July 25th, 2003. Oral feeding with breast milk was started within one hour of birth, and weight gain, feeding tolerance, nosocomial infection rate as well as other associated problems of pre-maturity, and postnatal growth curve were recorded upto 16th postnatal day. Seventy three percent of the newborns tolerate breast milk well from the very beginning, and the rest did not tolerate initially but all of them tolerate within 24 hours of birth. Infants had less initial weight loss (20 ± 10 gm) and faster recovery of birth weight. They regained their birth weight at 12th postnatal day. Hyper-bilirubinaemia was found in only 22% cases, and was observed in the group who initially didn't tolerate breast milk and was on intravenous fluid. Nobody developed symptomatic hypoglycemia or necrotizing enterocolitis (NEC). Two cases of sepsis and another two cases of minor infection like conjunctivitis and oral thrush have occurred. In conclusion it can be said that early breast milk feeding is safe in preterm VLBW infants and it helps to promote growth and reduce the need for intravenous line.

Correlation of triglyceride level with acute coronary syndrome. Mymensingh Med J 2012; 21:44-48. [PMID: 22314453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/31/2023]
Abstract
The study was aimed to find out the correlation of serum triglyceride level with acute coronary syndrome. This cross sectional study was conducted in the department of cardiology, Mymensingh Medical College Hospital, from August 2009 to May 2010. Socio-demographic characteristics, smoking habit, hypertension, serum total cholesterol level, serum HDLc, Serum LDLc, TG level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) and 50 healthy persons (control). Investigations included ECG, cardiac enzyme (troponin I), FBS and lipid profile. The data were analyzed by computer with the help of SPSS. Chi-square Test, T-test & ANOVA test were used as test of significance. The mean level of TG in acute coronary syndrome (ACS) patients (cases) was 168.2±58.0 mg/dl and in control were 141.2±45.3 mg/dl. So serum TG level is significantly higher in patients with ACS (p=0.01). In multivariate regression analysis, there was a significant association of elevated TG with risk of ACS (relative risk) is the highest, compared with the lowest quarantile = 1.011; 95% confidence interval (CI = 1.002 - 1.020; P for trend = 0.01). The relation of TG level to HDLc was a strong predictor of ACS (RR in the highest) compared with lowest quarantile = 0.02; (95% CI = 0.003 - 0.173; P for trend <0.0001). The study revealed that high level of serum triglyceride is associated with ACS. Categorization of patients with ACS on the basis of TG level may be helpful for risk stratification and management.

Abstract
A 26 years old Bangladeshi man experienced sudden gross haematuria for 10 days when he was working in Italy in June'07 that was resolved spontaneously. Six months' later he again developed haematuria and was admitted into an Italian hospital for its evaluation and management. In the mean time, he developed low grade fever, cough, back pain, spinal angulations, walking difficulty. His X-ray chest postero-anterior view revealed cavitary lesions in upper zones of both lung fields. Intravenous Urography (IVU) was done which revealed hydronephrosis and hydroureter of left kidney. Magnetic Resonance Imaging (MRI) of dorso-lumber spine revealed collapse of D10-12 and L4-5 vertebral bodies with perivertebral and epidural abscess. Sputum and urine smear for Acid-Fast-Bacilli (AFB) demonstrated the organisms on Z-N stain and AFB culture and sensitivity demonstrated that it was resistant to isoniazide, Rifampicin and streptomycin and diagnosed as primary disseminated multi-drug Resistant tuberculosis (MDR-TB). Second-line drugs were started in Italy on 15th January'08 and were continued thereafter in National Institute of Diseases of the Chest and Hospital (NIDCH). A ureteric stent which was given in Italy to get relief of hydro-ureter was removed in Dhaka. A neurosurgery (costo-transversectomy with decompression of spine) was done in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and patient get relief of back pain paresthesia. Lastly, his sputum and urine AFB smear and AFB culture became negative. So, primary disseminated MDR-TB with renal, spinal and pulmonary involvement was diagnosed in this Bangladeshi man who had a sputum AFB culture and sensitivity during his initial diagnostic work-up in Italy. It's an alarming case that demonstrated necessity of sputum AFB culture and sensitivity during initial diagnostic work-up.

Pancreatic lipomatosis with massive steatorrhea. Mymensingh Med J 2011; 20:712-714. [PMID: 22081194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/31/2023]
Abstract
Fat replacement of the exocrine pancreas is a rare cause of exocrine pancreatic failure. We report a case of 32-year-old man with weight loss and massive steatorrhea in whom abdominal computed tomography (CT) was diagnostic of pancreatic lipomatosis. The diagnosis was confirmed by needle aspiration cytological (FNAC) examination. Then oral pancreatic enzyme replacement in association with cimetidine led to a marked reduction of steatorrhea and weight gain. In this report it is emphasized that this lipomatosis can be demonstrated by non-invasive technique using abdominal CT-scan.

Abstract
The observed temperatures in different landfills are used to establish a number of idealized time-temperature histories for geomembrane liners in municipal solid waste (MSW) landfills. These are then used for estimating the service life of different HDPE geomembranes. The predicted antioxidant depletion times (Stage I) are between 7 and 750 years with the large variation depending on the specific HDPE geomembrane product, exposure conditions, and most importantly, the magnitude and duration of the peak liner temperature. The higher end of the range corresponds to data from geomembranes aged in simulated landfill liner tests and a maximum liner temperature of 37 degrees C. The lower end of the range corresponds to a testing condition where geomembranes were immersed in a synthetic leachate and a maximum liner temperature of 60 degrees C. The total service life of the geomembranes was estimated to be between 20 and 3300 years depending on the time-temperature history examined. The range illustrates the important role that time-temperature history could play in terms of geomembrane service life. The need for long-term monitoring of landfill liner temperature and for geomembrane ageing studies that will provide improved data for assessing the likely long-term performance of geomembranes in MSW landfills are highlighted.

Camptomelic dysplasia with sex reversal. Mymensingh Med J 2005; 14:80-3. [PMID: 15695962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/01/2023]
Abstract
Camptomelic dysplasia is a disorder of the newborn characterized by congenital bowing and angulation of long bones together with other skeletal and extraskeletal defects. The affected newborn had dysmorphic features with bowing of the legs and bilateral talipes equinovarus. Radiology showed marked anterior bowing of both tibia with disproportionately short fibula, anterolateral bowing of the femurs and wide pelvic outlet with small iliac wings. She had sex reversal with normal female genitalia and 46, XY karyotype. Camptomelic dysplasia is generally considered to be a lethal skeletal dysplasia and most patients die in the neonatal period due to severe respiratory distress. Survivors may have learning difficulties, developmental delay, conductive hearing loss, myopia and recurrent chest infections. Because of its high associated mortality, prenatal diagnosis of camptomelic dysplasia is mandatory. The birth of a child with skeletal dysplasia is an emotionally difficult experience for parents.

Dietary calcium intake in premenopausal Bangladeshi women: do socio-economic or physiological factors play a role? Eur J Clin Nutr 2003; 57:674-80. [PMID: 12771968 DOI: 10.1038/sj.ejcn.1601597] [Citation(s) in RCA: 29] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/19/2002] [Indexed: 11/09/2022]
Abstract
OBJECTIVE Evaluation of data on dietary calcium intake in premenopausal women of two socio-economic groups in Bangladesh. DESIGN A cross sectional study. Three days dietary records were used to estimate habitual calcium intake. SETTING Two regions of Bangladesh. The Dhaka city area and the Betagair Union in the sub-district Nandail, Mymensingh. SUBJECTS A total of 191 subjects of two groups (low socio-economic group=group L, n=101 and high socio-economic group=group H, n=90) of Bangladeshi women aged 16-40 y. About 87% of the subjects were housewives and the rest 13% were distributed in other different professions. Each group consisted of three sub-groups (non-pregnant non-lactating=1, pregnant=2 and lactating=3). RESULTS : The influence of socio-economic status on dietary intake of calcium (P<0.001) was observed in this study. The dietary intake of calcium was influenced by physiological status (PS) in high income group only (P<0.005). The mean dietary calcium intake was significantly higher (P&<0.005) in all sub-groups of this group compared with the corresponding sub-groups in low income group. Although in group H, 47% of subjects failed to meet even the lowest level (400-500 mg/day) of WHO recommended dietary allowances (RDA) of calcium for adult women. No subject in group L was found to meet the RDA level. Moreover, 63% of the women in group L had calcium intake lower than 200 mg/day. These figure could be more critical in both groups if we consider the recent USA-RDAs of calcium for adult women (1000 mg/day). The observed sources of dietary calcium were different in the two groups. CONCLUSIONS The results of the study suggested that low calcium intake could reduce the bone accretion rates and increase the risk of osteoporosis in the subjects of the present study. Calcium rich food may be recommended for women in both groups.
