Abstract
The data set explores the driving factors of migration of rural people to the cities. Primary data were collected purposively from 172 farm households from three upazilas of kishoreganj district in Bangladesh. Among 172 households, 89 households had at least one migrant member and 83 households were without any migrant member. Probit model was used to analyze factors of migration decision at the household level. Data set reveals that various factors motivate the decision of the farm households for their member to move into the city. Among which household head age, number of active male member in the family and value of the household asset holding significantly influence migration decision. Beside econometric analysis, household's perception on different motivating factors of migration was also assessed. Most of the households perceived that too many family members, poor living condition, migrant's family influence and job availability in the city mostly motivate the people for migration into the city along with other driving factors.

Abstract
This study unveils the electrochemically-enhanced nanozymatic activity exhibited by borophene during the reaction of 3,3',5,5'-tetramethylbenzidine (TMB) and H2O2. Herein, the surface of the pristine borophene was first modified with the addition of thiocyanate groups to improve hydroxyl radical (•OH) scavenging activity. Then, the oxidation reaction of TMB was accelerated under applied electrochemical potential. Both factors significantly improved the detection limit and drastically decreased the detection time. DPPH testing revealed that the radical scavenging nature of borophene was more than 70%, boosting its catalytic activity. In the presence of H2O2, borophene catalyzed the oxidation of TMB and produced a blue-colored solution that was linearly correlated with the concentration of H2O2 and allowed for the detection of H2O2 up to 38 nM. The present finding was further extended to nanozymatic detection of tetracyclines (TCs) using a target-specific aptamer, and the results were colorimetrically quantifiable up to 1 μM with a LOD value of 150 nM. Moreover, transferring the principles of the discussed detection method to form a portable and disposable paper-based system enabled the quantification of TCs up to 0.2 μM. All the sensing experiments in this study indicate that the nanozymatic activity of borophene has significantly improved under electrochemical potential compared to conventional nanozyme-based colorimetric detection. Hence, the present discovery of electrochemically-enhanced nanozymatic activity would be promising for various sensitive and time-dependent colorimetric sensor development initiatives in the future.

Abstract
Chronic obstructive pulmonary disease (COPD) remains a major public health problem with relatively high prevalence rates worldwide (5.0-13.0%). COPD is a major cause of morbidity and mortality worldwide and results in an economic and social burden that is both substantial and increasing. The purpose of the study was to explore the relationship of biochemical alterations of serum magnesium and uric acid with frequent exacerbations, hypoxia, increase hospital stay, morbidity and mortality in patients with COPD. This cross-sectional study was carried out in the Department of Biochemistry, Mymensingh Medical College, Bangladesh from January 2021 to December 2021. Data was collected from Medicine Department of Mymensingh Medical College Hospital, Bangladesh. A total number of 120 subjects participated in this study. Out of them, 60 apparently normal healthy individuals were selected as Group I and another 60 diagnosed COPD patients were selected as Group II. The results were calculated and analyzed by using statistical package for social science (SPSS), windows package version 21.0. Serum magnesium was measured by photoelectric colorimetric method using the test kit and serum uric acid was measured by enzymatic colorimetric method using the test kit. Data were expressed in mean±SD and statistical significance of different parameter was done by Pearson's correlation co-efficient test. The mean±SD values of serum magnesium were 2.15±0.29mg/dl and 1.54±0.30mg/dl in Group I and Group II respectively. Result was statistically highly significant (p<0.001). The mean±SD values of serum uric acid were 5.43±2.05mg/dl and 6.86±1.61mg/dl in Group I and Group II respectively. Result was statistically highly significant (p<0.001). Pearson's correlation coefficient test showed that there was significant (p=0.001) negative correlation (r= -0.415) found between serum magnesium and serum uric acid in study group. In this study, the result suggested that there was significant relation between COPD exacerbations and alteration of these biochemical parameters. So, by this study we recommended that routine evaluation of these parameters is important for prevention of exacerbations, reduction of morbidity and mortality in patients with COPD.

Abstract
MINERvA has measured the ν_{μ}-induced coherent π^{+} cross section simultaneously in hydrocarbon (CH), graphite (C), iron (Fe), and lead (Pb) targets using neutrinos from 2 to 20 GeV. The measurements exceed the predictions of the Rein-Sehgal and Berger-Sehgal PCAC based models at multi-GeV ν_{μ} energies and at produced π^{+} energies and angles, E_{π}>1 GeV and θ_{π}<10°. Measurements of the cross-section ratios of Fe and Pb relative to CH reveal the effective A scaling to increase from an approximate A^{1/3} scaling at few GeV to an A^{2/3} scaling for E_{ν}>10 GeV.

Abstract
While the nervous system has reciprocal interactions with both cancer and the immune system, little is known about the potential role of tumor associated nerves (TANs) in modulating anti-tumoral immunity. Moreover, while peri-neural invasion is a well establish poor prognostic factor across cancer types, the mechanisms driving this clinical effect remain unknown. Here, we provide clinical and mechniastic association between TANs damage and resistance to anti-PD-1 therapy. Using electron microscopy, electrical conduction studies, and tumor samples of cutaneous squamous cell carcinoma (cSCC) patients, we showed that cancer cells can destroy myelin sheath and induce TANs degeneration. Multi-omics and spatial analyses of tumor samples from cSCC patients who underwent neoadjuvant anti-PD-1 therapy demonstrated that anti-PD-1 non-responders had higher rates of peri-neural invasion, TANs damage and degeneration compared to responders, both at baseline and following neoadjuvant treatment. Tumors from non-responders were also characterized by a sustained signaling of interferon type I (IFN-I) - known to both propagate nerve degeneration and to dampen anti-tumoral immunity. Peri-neural niches of non-responders were characterized by higher immune activity compared to responders, including immune-suppressive activity of M2 macrophages, and T regulatory cells. This tumor promoting inflammation expanded to the rest of the tumor microenvironment in non-responders. Anti-PD-1 efficacy was dampened by inducing nerve damage prior to treatment administration in a murine model. In contrast, anti-PD-1 efficacy was enhanced by denervation and by interleukin-6 blockade. These findings suggested a potential novel anti-PD-1 resistance drived by TANs damage and inflammation. This resistance mechanism is targetable and may have therapeutic implications in other neurotropic cancers with poor response to anti-PD-1 therapy such as pancreatic, prostate, and breast cancers.

Abstract
Neutrino-induced charged-current single π^{+} production in the Δ(1232) resonance region is of considerable interest to accelerator-based neutrino oscillation experiments. In this Letter, high statistic differential cross sections are reported for the semiexclusive reaction ν_{μ}A→μ^{-}π^{+}+ nucleon(s) on scintillator, carbon, water, iron, and lead targets recorded by MINERvA using a wideband ν_{μ} beam with ⟨E_{ν}⟩≈6 GeV. Suppression of the cross section at low Q^{2} and enhancement of low T_{π} are observed in both light and heavy nuclear targets compared with phenomenological models used in current neutrino interaction generators. The cross sections per nucleon for iron and lead compared with CH across the kinematic variables probed are 0.8 and 0.5 respectively, a scaling which is also not predicted by current generators.

Abstract
This Letter presents the first simultaneous measurement of the quasielasticlike neutrino-nucleus cross sections on C, water, Fe, Pb, and scintillator (hydrocarbon or CH) as a function of longitudinal and transverse muon momentum. The ratio of cross sections per nucleon between Pb and CH is always above unity and has a characteristic shape as a function of transverse muon momentum that evolves slowly as a function of longitudinal muon momentum. The ratio is constant versus longitudinal momentum within uncertainties above a longitudinal momentum of 4.5 GeV/c. The cross section ratios to CH for C, water, and Fe remain roughly constant with increasing longitudinal momentum, and the ratios between water or C to CH do not have any significant deviation from unity. Both the overall cross section level and the shape for Pb and Fe as a function of transverse muon momentum are not reproduced by current neutrino event generators. These measurements provide a direct test of nuclear effects in quasielasticlike interactions, which are major contributors to long-baseline neutrino oscillation data samples.

Abstract
Heart failure means that the heart is unable to pump blood around the body properly. It usually happens because the heart has become too weak or stuff. In collaboration with department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh this cross-sectional study from January to December 2018 was performed in the department of Biochemistry in Mymensingh Medical College, Mymensingh, Bangladesh. The aim of this study was to explore the relationship of serum creatinine in patients with heart failure (HF) for management purpose. In this study 120 subjects were included, where 60 patients of diagnosed HF acts as case group and 60 individuals were normal healthy acts as control group. Serum creatinine was determined by colorimetric method from each sample. Statistical analysis was performed by SPSS windows package, version 21. Among the study groups the mean serum creatinine levels were 2.20±0.87mg/dl and 0.92±0.26mg/dl in case and control group respectively. Analysis showed that the mean serum creatinine level was highly significantly (p<0.001) increased in HF patients in comparison to that of control group.

Abstract
Adequate knowledge about the causes of chronic kidney disease and their potential prevention can improve poor clinical outcome in chronic kidney disease (CKD) patients. The study was designed to evaluate the serum albumin and C-reactive protein (CRP) levels in hospitalized patients with Chronic Kidney Disease. This cross-sectional study was carried out in the Department of Biochemistry, Mymensingh Medical College, Mymensingh, Bangladesh with the collaboration of the Department of Nephrology, Mymensingh Medical College Hospital, Mymensingh, from January 2021 to December 2021. The subjects were selected on the basis of inclusion and exclusion criteria by purposive and convenient sampling method. A total of 110 subjects were included in this study. Among them, 55 were diagnosed CKD patients denoted as Group I and 55 were normal healthy individuals denoted as Group II. In this study, serum albumin and CRP levels were measured. All values were expressed as Mean±SD. All statistical analysis was done by using SPSS (statistical package for social science) windows package version 21.0. Statistical significance of difference between Group I and Group II were evaluated by using student's unpaired 't'-test and the significance was defined as p<0.05. Correlation was done by using Pearson's correlation coefficient test. Mean age of Group I was 52.65±4.93 and Group II was 51.15±6.32 (p=0.165). The mean±SD of BMI was 24.46±1.84 for Group I and 24.50±1.05 for Group II (p=0.886). The mean±SD values of serum albumin were 3.62±0.26g/dl and 4.16±0.69g/dl in Group I and Group II respectively. We found highly significant (p<0.001) decrease in serum albumin. The mean±SD values of CRP were 24.00±16.73mg/L and <6.0±0.00mg/L in Group I and Group II respectively. So, we found significant (p<0.05) increase in CRP levels. There was negative correlation between serum albumin and CRP. Analyzing the findings of this study, significant decrease in serum albumin and significant increase in CRP levels were observed in CKD patients.

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

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

Abstract
Encephalitis is commonly caused by viruses. But beyond viruses there are so many causes of encephalitis. Encephalitis is the inflammation of the brain parenchyma due to any reason. As there are so many causes of encephalitis presentations are also variable. So to diagnose encephalitis a set of clinical, laboratory, electroencephalographic and neuroimaging criteria is used. Any children attend medical facility with sudden onset altered mental status along with any of the following features like fever, seizure, focal neurological signs should be evaluated as encephalitis. Viruses are the common cause of encephalitis. Along with infectious etiologies a vast group of noninfectious like autoimmune causes encephalitis also established. When children presented with above mentioned features along with behavior problem and or movement disorder there is a high suspicion of autoimmune etiology. Any suspected case of encephalitis should initiated treatment with antiviral along with supportive treatment; then step wise evaluation should be done to reach an etiological diagnosis. If infectious etiology could not be established or no significant improvement is found with antiviral therapy; immunomodulating therapy should be considered along. In all cases CSF analysis including biochemistry, cytology, viral PCR along with MRI and EEG should do; further investigations depend upon initial reports and clinical and epidemiological background. Dose and duration of antiviral depends on patient's age and response to treatment and comorbidity. Acyclovir 500mg/m²/BSA per dose 3 times daily for 21 days are adequate for HSV encephalitis. Monitoring of renal function is the essential. Adjuvant treatment with steroid and or manitol for cerebral edema and antiseizure drugs for convulsion is used where necessary. Meticulous fluid and nutritional support as well good general care improve outcome. In spite of adequate treatment of encephalitis mortality and morbidity was found a significant number of cases; among the morbidity behavior problem, seizure focal deficit are common.

Abstract
Neutrino charged-current quasielastic-like scattering, a reaction category extensively used in neutrino oscillation measurements, probes nuclear effects that govern neutrino-nucleus interactions. This Letter reports the first measurement of the triple-differential cross section for ν_{μ} quasielastic-like reactions using the hydrocarbon medium of the MINERvA detector exposed to a wideband beam spanning 2≤E_{ν}≤20 GeV. The measurement maps the correlations among transverse and longitudinal muon momenta and summed proton kinetic energies, and compares them to predictions from a state-of-art simulation. Discrepancies are observed that likely reflect shortfalls with modeling of pion and nucleon intranuclear scattering and/or spectator nucleon ejection from struck nuclei. The separate determination of leptonic and hadronic variables can inform experimental approaches to neutrino-energy estimation.

Abstract
This cross sectional study was conducted in Paediatric Endocrine Outpatient Department of BIRDEM General Hospital, a tertiary care centre in Dhaka, Bangladesh among patients diagnosed with congenital adrenal hyperplasia (CAH) from January 2005 to December 2018. The study was aimed to find out the clinical and laboratory profile of all patients at presentation diagnosed with CAH during the study period. Data were obtained by reviewing the medical records of the patients. Total 102 children with CAH were diagnosed during the study period. Among them 68 were female and 34 were male (female to male ratio of 2:1). Median age was 3.5 month (range 0.2-158 month) and 5.5 month (range 1-108 month) in female and male respectively (p=0.42). Family history was available in 93 patients. Consanguinity was present in 16(17.2%), history of sib death in 12(12.9%), other family members were affected in 8(8.6%). Sixty patient (58.8%) had salt-wasting (SW), 39(38.2%) had simple virilizing (SV) and 3(2.9%) had non- classic form of CAH. Median age of presentation was 2 month (range 0.2-70 month) and 42 month (range 0.8-158 month) in SW and SV group respectively (p=0.001) and 119 month (range 108-152 month) in non- classic group. Common presentations were: genital ambiguity (64.7%), vomiting (46.5%), failure to thrive (41.6%), features of early puberty (precocious pseudopuberty) (24.5%), diarrhea (12.0%). Hyperpigmentation was noted in 49.0% of patients. Among the salt-wasting type in male failure to thrive (FTT) was the most common presentation (83.3%), followed by vomiting (75.0%). In female genital ambiguity was the commonest presentation (97.2%), followed by vomiting (77.1%). Among the simple virilizing type in male early puberty was the commonest presentation (100%) and genital ambiguity was the presenting feature in all the female (100.0%).

Abstract
Background: Species identification in commercially processed food and feed products is one of the important issues. This study was conducted to develop a genetic method for the detection of pig and cattle species in processed food and feed products using newly designed species-specific primers targeting mitochondrial 12S rRNA gene fragments.
Methods: Two sets of specific primers were designed based on the 12S rRNA gene sequences of pig and cattle species from GenBank. The primers were validated by using the DNA extracted from nine different chordates, including pig, cattle, chicken, bata fish, bat, toad, African parrot, rat, and human origin. Annealing temperature ranging from 46-54°C for 30 seconds and template DNA 1:10 serial dilutions ranging from 10 to 0.00001 ng/µl were employed for primer annealing and sensitivity analysis. Samples were analyzed using optimized Polymerase Chain Reaction (PCR) conditions.
Results: The most intense expected DNA bands of pig and cattle were produced at 50°C. Under that optimized annealing temperature pig and cattle-specific primers did not anneal with the DNA of other chordates. Total extracted DNA 0.001 ng and 0.01 ng of pig and cattle respectively containing the mitochondrial DNA (mtDNA) was successfully detected.
Conclusion: These findings indicate that the newly designed primer pairs can be used to detect pig and cattle derivatives in various processed food and feed products.

Abstract
The Coronavirus disease 2019 (COVID-19) has turned into a worldwide human tragedy and economic devastation. There had an intensive search for an effective drug against the coronavirus but not led to any breakthrough agents. Only one choice was left namely an effective and safe vaccine. Many people are ambivalent regarding corona vaccines because they also fear possible side effects from vaccination. This study was designed to track the side effects after first and second dose of the Oxford-AstraZeneca vaccines used in Mymensingh district of Bangladesh. This cross-sectional descriptive type of observational study was conducted in Mymensingh Medical College, Mymensingh, Bangladesh during the period of five months from 1 February, 2021 to 30 June, 2021 among 293 purposively selected vaccine recipients who received two doses of the Oxford-AstraZeneca vaccines. Data were collected by face to face interview of the selected vaccine recipients using a semi-structured questionnaire. Data were inputted into SPSS version 26.0. Qualitative data were summarized by percentage and quantitative data were summarized by mean and standard deviation. Necessary bivariate and multivariate analysis was done. Mean age of the respondents was 40.3 years with a standard deviation of ±8.7 years. Among the vaccine recipients female were 159(54.3%) and male were 134(45.7%). The most of the vaccine recipients were graduate and master 256(87.3%) and more than half of the vaccine recipients (156, 53.2%) were government service holder. The most of the vaccine recipients (242, 86.0%) were from urban area and 263(89.8%) vaccine recipients were non-smoker. Sixty eight (23.2%) of the vaccine recipients had different types of co-morbidities. It was found that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects after second dose. The difference in occurrence of side effects of first and second dose was statistically highly significant (p<0.001). Pain on the injection site was present in 172(58.7%) vaccine recipients after first dose and in 142 (48.5%) after second dose. Fever was prevalent in 98 (33.4%) after first dose and in 61 (20.8) after second dose. Headache was in 61(20.8%) and in 22(7.5%) after first and second dose respectively. Thirty one (10.6%) vaccine recipients had loose motion after first dose and 26(8.9%) had this after second dose. First dose of vaccination caused nausea in 28(9.6%) and second dose caused it in 16(5.5%) vaccine recipients. Joint pain was prevalent in 24(8.2%) after first dose and in 15(5.1%) after second dose. Rash was present in 9(3.1%) and in 3(1.0%) after first and second dose respectively. Cough was present in 5(1.7%) after first dose and in 2(0.7%) after second dose. Each 2(0.7%) had history of fainting and bodyache and 1(0.3%) reported intense weakness after first dose only. Side effects of first dose of AstraZeneca vaccine were more prevalent in female (124, 78.0%) than male (93, 69.4%). The side effects of second dose of AstraZeneca vaccine were also more prevalent in female (103, 64.8%) than male (59, 44.0%). The study results revealed that 217(74.1%) vaccine recipients had side effects after first dose while 162(55.3%) had side effects on second dose of the Oxford-AstraZeneca vaccine. Commonly experienced side effects were pain in the injection site, fever, headache, diarrhoea and joint pain. Most of the people tolerated these side effects and did not use any medicine.

Abstract
The objective of the current study was to investigate the synergistic impact of α-Tocopherol and α-Linolenic acid (100 µM) on IVM and IVC of Nili Ravi buffalo oocytes. Oocytes were obtained from the ovaries of slaughtered buffaloes within two hours after slaughter and brought to laboratory. Buffalo cumulus oocyte complexes were placed randomly in the five experimental groups included; GROUP 1: Maturation media (MM) + 100 µM ALA (control), GROUP 2: MM + 100 µM ALA + 50μM α-Tocopherol, GROUP 3: MM + 100 µM ALA + 100μM α-Tocopherol, GROUP 4: MM + 100 µM ALA + 200 μM α-Tocopherol and GROUP 5: MM + 100 µM ALA + 300 μM α-Tocopherol under an atmosphere of 5% CO2 in air at 38.5 °C for 22-24 h. Cumulus expansion and nuclear maturation status was determined (Experiment 1). In experiment 2, oocytes were matured as in experiment 1. The matured oocytes were then fertilized in Tyrode's Albumin Lactate Pyruvate (TALP) medium for about 20 h and cultured in synthetic oviductal fluid (SOF) medium to determine effect of α-Linolenic acid (100 µM) and α-Tocopherol in IVM medium on IVC of presumptive zygotes. To study the effect of α-Linolenic acid (100 µM) in IVM media and increasing concentration of α-tocopherol in the culture media on early embryo development (Experiment 3), the presumptive zygotes were randomly distributed into the five experimental groups with increasing concentration of α-tocopherol in culture media. Higher percentage of MII stage oocytes in experiment 1(65.2±2.0), embryos at morula stage in experiment 2 (30.4±1.5) and experiment 3 (22.2±2.0) were obtained. However, overall results for cumulus cell expansion, maturation of oocyte to MII stage and subsequent embryo development among treatments remain statistically similar (P > 0.05). Supplementation of α-tocopherol in maturation media having α-Linolenic acid and/or in embryo culture media did not further enhance in vitro maturation of oocyte or embryo production.

Abstract
BACKGROUND Here, we have shortly reported the recent updates on the disastrous progressions of the deadly delta variant and a virulent coinfection or post-COVID-19 infection of black fungus in India and its neighbouring countries. METHODOLOGY We searched by utilizing appropriate keywords in Google Scholar, PubMed and other scholarly databases alongside several national and international newspapers to collect the latest data regarding the targeted topic. RESULTS Recently, the delta variant is wreaking havoc in India, UK, and other countries around the globe and has also exhibited successful infections in around 20 to 55% of the people who have already recovered from COVID-19 originating from the different strains. Besides, a significant catch is the prevalence of 85.5% and 64.11% of Mucormycosis infections being co-morbid with COVID-19 and diabetes, respectively in South-Asian regions. CONCLUSIONS To avert the emergence of an epidemic amid the pandemic, prompt actions from concerned authorities are warranted. Proper education on black fungus infection and associated risks from the COVID-19 and diabetes, adequate public awareness, and sufficient healthcare assistance to battle such fungal infections effectively should be ensured as quickly as possible.

Abstract
BACKGROUND Egg yolk is inevitably associated with risks of microbial contamination and anti-cryoprotectant agents that necessitate the investigation of some synthetic alternatives. OBJECTIVE To investigate the potential of carboxylated poly-L-lysine (CPLL) as a replacement for egg yolk during the cryosurvivability of Nili-Ravi buffalo sperm. MATERIALS AND METHODS Semen collected from four Nili-Ravi buffalo bulls (two ejaculates / bull / day; total 40 ejaculates for five replicates) was cryopreserved in different experimental extenders viz: Control (CPLL 0%, egg yolk 20%); E1 (CPLL 5%, egg yolk 15%); E2 (CPLL 10%, egg yolk 10%); E3 (CPLL 15%, egg yolk 5%) and E4 (CPLL 20%, egg yolk 0%). Post-thaw quality was assessed in terms of sperm motility, plasma membrane integrity (PMI), viability, live:dead ratio, lipid peroxidation of sperm and total antioxidant capacity of seminal plasma. RESULTS Sperm motility improved (P<0.05) in extenders replacing 5%, 10% and 15% egg yolk with CPLL. Sperm PMI, viability and live:dead ratio also improved (P<0.05) in extenders replacing 10%, 15% and whole (20%) egg yolk with CPLL. In contrast, sperm DNA integrity was not different (P>0.05) when CPLL replaced egg yolk at any level. The lipid peroxidation level decreased with a concomitant increase in total antioxidant activity of seminal plasma when CPLL replaced egg yolk at 5%, 10%, 15% and 20%. CONCLUSION Replacement of 15% egg yolk in the extender with CPLL improves all sperm quality parameters: motility, PMI, viability, live:dead ratio, lipid peroxidation of sperm and total antioxidant activity of seminal plasma.

Abstract
A model to predict Nili-ravi buffalo bull fertility was developed based on Fourier harmonic analysis of sperm. Seventeen bulls with 3032 AI records were categorizes based on fertility rate (FR) as low (36.5±0.2, n = 6: SD< ˗1 from mean FR), medium (39.9±0.2, n = 3; SD +1 to -1 from mean FR) and high fertility (41.4±0.1, n = 8; SD > +1 from mean FR). Cryopreserved semen samples from these bulls were investigated for Fourier harmonic analysis of sperm nuclear shape. Hoechst-33342 and YOYO-1 fluorescent stains were used to identify live and dead sperm. Digital images were analyzed to get sperm nuclear perimeter points at different phase angles to generate Fourier functions. Mean harmonic amplitude (HA) 0 was different (P < 0.05) for 1700 live vs. 1294 dead sperm from the 17 bulls, thus live sperm were used for remaining analyses. The mean, variance, skewness and kurtosis values of 100 live sperm nuclei/bull were compared for HA0-5 between high (n = 6) and low (n = 6) fertility groups, considering equal number of bulls in each category. The mean HA2 (0.739±0.01 vs 0.686±0.00) and 4 (0.105±0.001 vs 0.007±0.001) were higher in high vs low fertility group respectively (P < 0.05). Sperm nuclear perimeter among high fertility group sperm was more elongated. There was also an increased skewness of HA0 as fertility increased (P < 0.05). Discriminant analysis defined a fertility model by using mean HA4, skewness HA0 and variance HA2, that resulted in 91.7% bulls into their correct fertility group upon cross-validation (canonical correlation=0.928; P < 0.05). Higher values of mean HA4, skewness HA0 and variance HA2 increase the chance of bulls being placed in the high fertility group. In conclusion, sperm nuclear shape in Nili-ravi buffalo bull is related to in vivo fertility. A fertility model using reported discriminant measures could be used to objectively identify Nili-ravi buffalo bulls of varying fertility.

Abstract
Uterine leiomyoma is a common gynecological problem throughout the world. As 50% hysterectomies in black and 40% in Australians are performed due to fibroid, in our country also it is assumed that about 40%-50% hysterectomies are done due to fibroid uterus. Thus leiomyoma constitute a major public health cost to the community in terms of outpatient attendance and hospital cost for surgery. This is a descriptive type of cross sectional study among 50 patients having leiomyoma of uterus in the department of Obs and Gynae, BSMMU hospital from March 2011 to August 2011. The objective of the study is to find out the risk associated with leiomyoma, to find out the common presenting features of uterine leiomyoma and to find out best options for management. Study results showed that 62% patients were in the age group 36-45 years, 48%patients were in para1-2 group, 32% patients used combined oral contraceptive pill for contraception. Sixty percent (60%) patients presented with progressive menorrhagia and palpable mass was found in 62% cases. About 46% patients had associated medical conditions like hypertension, diabetes, obesity. Total abdominal hysterectomy was done in 32% cases. TAH with unilateral or bilateral salpingoophorectomy was done in 40% cases. Myomectomy was done in 20% cases. There is a scope for large scale study about risk factors of uterine leiomyoma like obesity, diabetes mellitus, hypertension, use of hormonal contraceptive, racial differences, different treatment modalities etc. Treatment should be individualized. However in this connection a good referral system and good communication has got a tremendous contribution in the proper management of such problems.

Abstract
Congenital CMV infection is the most common mother to child infection having spectrum of clinical presentation which can lead to severe neurological sequelae. Early assessment of disease severity from clinical and neuroimage profile is essential to initiate proper treatment and to predict the outcome is crucial. This cross sectional observational study was conducted at Dhaka Medical College Hospital a tertiary care centre of Bangladesh from January 2019 to June 2020 in the department of pediatrics. This study was carried on among 123 infants of aged 0-12 months with polymerase chain reaction proven congenital cytomegalovirus infection over a period of 18 months. Mean age of our study group is 7.01±2.02 months, with male predominance (85.00%); majority of our infants came from lower socioeconomic background of rural area. Only 5.70% took more than two antenatal visits, 70.00% had history of perinatal asphyxia where 54.50% developed neonatal seizure. Microcephaly was present among 69.10% children, epilepsy, movement disorder, central visual impairment, different level of hearing impairment (78.90%) and severe psychomotor retardation (83.80% - 87.80%) was the most consistent initial presentation of our study group. Neuroimage abnormality was present among 94.30% of infants where cortical atrophy (86.20%) and intracranial calcification (55.30%) was the most common findings, different type of congenital malformations was also observed among the study group. Multiple logistic regression analysis showed significant value for abnormal neuroimage findings as a predictor of severity of psychomotor retardation. Congenital cytomegalovirus infection is one of the leading cause of hearing impairment and psychomotor retardation, where neuroimage findings could guide to predict the severity of psychomotor retardation.

Abstract
The Incidence of twin and high order multiple gestation has increased significantly over the past 15 years primarily because of the availability and increased use of ovulation inducing drugs and assisted reproductive technology. Both maternal and perinatal mortality and morbidity is higher in multiple pregnancy than in singleton pregnancy. Proposed study is designed to determine the incidence and obstetric outcome of multiple pregnancy which is a high-risk pregnancy in a tertiary referral hospital. The purpose of this study is to evaluate obstetric outcome of multiple pregnancy. This prospective observational study was carried out in the Department of Obs and Gynae, Mymensingh Medical College Hospital, Mymensingh from December 2011 to May 2012. Patients were selected by purposive way. In this study it was observed that incidence of twin pregnancy was 1.66% common age group 30-35 years (48%), common in multipara (74%), no pregnancy crossed EDD. Family history of twin was 32% and unknown etiology 58%. Most common maternal complication was preterm labour (60%). Commonest mode of delivery was LSCS (64%), incidence of perinatal mortality 15%, 36% baby had birth weight in between 2.1-2.5kg, all the baby requiring admission in neonatal unit. This prospective observational study revealed that perinatal mortality was high in our center, there was no maternal mortality.

Abstract
Abstract
Few advances have been made against head and neck cancers, in part because treatment efforts have focused on the epithelial component of these tumors. However, therapies targeting the microenvironment, including immune checkpoint blockade (ICB), also remain ineffective in the majority of head and neck cancers. Like some other immunotherapy-nonresponsive tumors, head and neck cancers develop a complex microenvironment heavily infiltrated by nerve fibers arising from the peripheral nervous system. Studies in multiple models have shown that the ablation of different portions of the peripheral nervous system prevents cancer development and progression. We recently showed that existing nerves sprout and undergo autonomic reprogramming to an adrenergic-like phenotype as a result of orchestrated microRNA (miRNA) shuttling from cancer cells to neurons, resulting in activation of transcriptional programs that establish new neuronal identity. Given that activated T-cell subsets express high levels of adrenergic receptors, we hypothesized that adrenergic signaling may also influence tumor-infiltrating T-cell function. We used novel murine models of OCSCC to discern the effect of adrenergic nerve signaling on immune infiltration and immunotherapy response and correlated our findings with data from patient cohorts using bulk and single-cell RNA sequencing. We found that adrenergic signaling acutely enhanced cytotoxic T-cell activity in patient-derived tumor/T-cell pairs, and we elucidated a p53-dependent mechanism underlying this effect. Ultimately, these results provide a striking contrast to the known role of adrenergic signaling in cancer development: although nerve-cancer crosstalk drives cancer aggression and progression, tumor innervation may also better enable the host immune response. Therapeutic approaches targeting this critical component of tumor biology may be useful to improve patients' survival, treatment responses, and quality of life.

Abstract
Background This is the first study to examine the costs of conducting a mobile phone survey (MPS) through interactive voice response (IVR) to collect information on risk factors for noncommunicable diseases (NCD) in three low- and middle-income countries (LMIC); Bangladesh, Colombia, and Uganda. Methods This is a micro-costing study conducted from the perspective of the payer/funder with a 1-year horizon. The study evaluates the fixed costs and variable costs of implementing one nationally representative MPS for NCD risk factors of the adult population. In this costing study, we estimated the sample size of calls required to achieve a population-representative survey and associated incentives. Cost inputs were obtained from direct economic costs incurred by a central study team, from country-specific collaborators, and from platform developers who participated in the deployment of these MPS during 2017. Costs were reported in US dollars (USD). A sensitivity analysis was conducted assessing different scenarios of pricing and incentive strategies. Also, costs were calculated for a survey deployed targeting only adults younger than 45 years. Results We estimated the fixed costs ranging between $47,000 USD and $74,000 USD. Variable costs were found to be between $32,000 USD and $129,000 USD per nationally representative survey. The main cost driver was the number of calls required to meet the sample size, and its variability largely depends on the extent of mobile phone coverage and access in the country. Therefore, a larger number of calls were estimated to survey specific harder-to-reach sub-populations. Conclusion Mobile phone surveys have the potential to be a relatively less expensive and timely method of collecting survey information than face-to-face surveys, allowing decision-makers to deploy survey-based monitoring or evaluation programs more frequently than it would be possible having only face-to-face contact. The main driver of variable costs is survey time, and most of the variability across countries is attributable to the sampling differences associated to reaching out to population subgroups with low mobile phone ownership or access.

Abstract
AbstractFarmers generally use more nitrogen fertilizer than others for crop production in Bangladesh because of its visible growth symptoms. Such practice is responsible for extra reactive N (Nr) load to the environment, but data are not available. Nitrous oxide (N2O) data were collected from a field trial following static closed-chamber technique, which were used for calibration and validation of DeNitrification and DeComposition model along with soil clay fraction, pH, bulk density and organic carbon contents. The model was well fitted and estimated about 364 g N2O–N ha−1 emission in Rajshahi region and only 15 g N2O–N ha−1 in Barisal region. District-wise N2O–N emissions varied from < 1–15.96 t season−1. In 2011–2016, N2O–N emissions from wheat fields were about 103–129 t yr−1 in Bangladesh. The model estimated nitric oxide (NO), ammonia (NH3) and nitrate (NO3) fluxes varied from 0.012 to 0.447, 7 to 12.5 and 0 to 4.7 kg N ha−1, respectively, under ambient temperature condition. In about 79% yield variabilities were explainable by N2O emission. In dominant wheat growing areas, if sowing is started from 15 to 30 November, N2O emission could be reduced by 8–40% with 5–13% reduction in yields compared to 10 November sowing. In similar areas and same sowing date with 1.5 °C temperature rise, N2O emission may increase by 8–45% and wheat yield might reduce by about 4–8%. Time of seeding and other cultural management in wheat cultivation would be the main avenue for reducing Nr loads to the environment.

Abstract
Intentional artificial rupture of the amniotic membranes during labour, called amniotomy or 'breaking of the water's, is one of the most commonly performed procedures in modern obstetric and midwifery practice. The primary aim of amniotomy is to speed up uterine contractions and therefore shorten the length of labour. However there are concerns regarding unintended adverse effects on the woman and baby. A prospective observational study was conducted to determine the effectiveness and safety of routine procedure of amniotomy to shorten the duration of labour (prolonged or not) in Mymensingh Medical College & Hospital, Mymensingh, Bangladesh from July 2011 to December 2011. One hundred low-risk women with spontaneous onset of labour at term with singleton fetus in cephalic presentation and intact amniotic membranes and a cervical dilatation between 4 and 5cm were conventionally assigned to have amniotomy during the course of labour. Maternal demographics, duration of labour (prolonged or not), maternal and perinatal outcome were considered as major outcome. Majority (49.0%) of the patients belonged to 21-25 years age group and primigravida was predominant and most of them had middle socio-economic conditions. More the three-fourth (89.0%) of the patients had head engaged. Rh-positive and negative were found 96.0% and 4.0% respectively. The primigravidae required 10.07±2.17 hours in 1st stage of labour and had 1.51±0.5 hours duration of 2nd stage of labour. In case of multi-gravidae it was 6.07±2.06 hours in 1st stage of and 1±0.5 hours in 2nd stage of labour. There was a marked reduction of amniotomy-delivery interval time in this study, which was 3 hours 40 minutes and whereas mean cervical dilatation was 4cm during amniotomy. Almost three fourth (72.0%) cases delivered vaginally among which, with episiotomy in 49.0% and without episiotomy in 23.0%. Instrumental delivery was in 9.0% of which 4.0% by forceps, 5.0% by vaccum extraction and 14.0% underwent LUCS. Still birth was found 2.0%, asphyxiated 3.0% and prenatal death 1.0%. In terms of referral to neonatal care unit it was found that 7.0% were asphyxiated. Asphyxia and low APGAR score was 4.0%, low birth weight 9.0%, instrumental delivery was 5.0%, Rh incompatibility was 2.0%. Only 1.0% babies needed admission to neonatal care unit and were intubated. So, Amniotomy significantly reduced the duration of the first stage of labour without affecting the oxytocin requirement, the rate of caesarean section and newborn outcome.

Abstract
Crop production in acid soils is facing enormous challenges due to low soil quality associated with an increase in the acidification rate and aluminum toxicity. Despite comprehensive prior work with biochar application on nutrient availability and crop productivity in acid soils, little information is available about the recommendation or standardization of biochar application rates that are more suitable for soil fertility improvement under different soil environments (physico-chemical properties) for maximizing the benefits of biochar applications and minimizing the potential environmental risk. Thus, the objective of this study was to investigate the effectiveness of poultry litter (PL) and poultry litter biochar (PLB) in ameliorating the fertility of acid soils through incubation and pot experiments. The soil was amended with different materials as follows; lime (1 g kg-1), PL (5, 10 and 15 g kg-1) and PLB (5, 10 and 15 g kg-1) along with control (non-amended). A pot experiment was also conducted using similar treatments to observe the responses of maize crop to the different amendments. The results indicated an increase in the pH and a decrease in exchangeable acidity in lime, PL and PLB amended soils. Lower soil pH, base cations and soil available phosphorus (P), and higher exchangeable acidity were found in control than the amended soils. Compared to PL and lime, PLB achieved greater increase rate in soil pH and reduction rate in soil exchangeable acidity with increased soil exchangeable base cations. An increase in soil available calcium (Ca) was observed in the lime treatment, while in PL and PLB treatments, there was an increase in soil available Ca, magnesium (Mg), potassium (K) and P. Application of the amendments increased availability of nitrogen (N), P, K, Ca and Mg relative to the control for maize in the pot experiment. When PL and PLB amendments were compared, it was found that the PLB was the best choice for the amelioration of acid soils as well as nutrient uptake by maize plants. It is suggested that application of PLB at the rate of 15 g kg-1 is suitable for maize growth in acid soils.

Abstract
Synthetic androgens (male hormones) administered to fish nursery are being used in aquaculture to avoid sexual differentiation and unwanted spawning at the eggs or the first feeding fry stage of fish. Present trial was conducted with the aim to produce male common carp (Cyprinus carpio) by egg immersion technique. Through this little insight, the effect of different hormone concentrations (17α-methyltestosterone @ HC:150, 300, 450 and 600 µgl-1) with immersion times (IT: 24, 48 and 72 hrs) and their interaction effect (HC x IT) on the hatching percentage of Cyprinus carpio eggs, percent survival and percent of male's production was evaluated specifically. Results showed that egg hatching percentage decreased with increased IT likewise, survival of treated fry was affected by increasing the IT (P<0.001). The main interaction effect of HC x IT showed that the highest percent of male individuals (95%) was obtained at 450-600 µgl-1 HC for 72 hrs IT, followed by 88-92.50% at 150-300 µgl-1 HC for 72-hrsof IT, 87.50% at 48-hrs of IT for rest of the hormone treatments, and lowest 47.50% was recorded in control (P<0.05). Increased percent male of Cyprinus carpio was obtained with increasing HC across all ITs. It was observed that the immersion treatment at 600µgl-1 for 72 hours was more effective to change the sex ratio of pre hatch Cyprinus carpio. A comparative outlook made from this experimental trial that sex induction of Cyprinus carpio by eggs immersion using synthetic male steroid hormone is an alternative safe technique of fish sex reversal in contrast to oral administration of hormone in fish feed.

Abstract
Rett syndrome is a disorder of early brain development which is clinically characterized by arrested neuro-development. We found one such 5.5 years old girl whose physical and mental development was normal up to 17 months of age, followed by regression. She had lost her already acquired purposeful hand movements, appearance of stereotyped hand movements, along with development of epilepsy. To our knowledge such case is being reported for the first time from Bangladesh. The purpose of this case report is to increase awareness of this syndrome among physicians specially paediatricians, thereby aiding early diagnosis and treatment.

Abstract
The present study investigates the efficacy of dimehtlyformamide (DMF) as a permeable cryoprotectant and its effect on quality and fertility of Indian red jungle fowl sperm. Semen was collected from eight mature roosters, pooled, divided into five aliquots and diluted with red fowl extender having DMF (0%, 4%, 6%, 8% and 10%). Diluted semen samples were cooled from 37 °C to 4 °C, 20% glycerol added to control (0% DMF), equilibrated for 10 min and filled in 0.5 mL French straws, kept over liquid nitrogen vapors for 10 min and plunged into liquid nitrogen. Sperm motility, plasma membrane functionality, viability and acrosome integrity were assessed at post dilution, cooling, equilibration and freeze-thawing stage of cryopreservation. Cryopreservation stages had negative effects (P < 0.05) on semen quality parameters. Percentages of sperm motility, plasma membrane functionality, viability and acrosome integrity were recorded highest in extender having 8% DMF at post-dilution, cooling, equilibration and freeze-thawing stage. Fertility results after artificial insemination were recorded higher (P < 0.05) with 8% DMF compared to 20% glycerol. Dimehtlyformamide (8%) in red fowl extender improves the post thaw semen quality and fertility in Indian red jungle fowl and can be used effectively to avoid the contraceptive effects of glycerol.

Abstract
The depth of intravaginal insemination to achieve optimum fertility with frozen-thawed semen is highly species specific in birds and differ even in breed and/or strains of a species. Therefore, study was designed to evaluate the influence of intravaginal insemination depths (2 and 4 cm) on fertility outcome in Indian red jungle fowl. Semen collected from eight mature cocks was pooled, diluted in extender and cooled to 4 °C. Glycerol (20%) was added to chilled semen, equilibrated for 10 min and cryopreserved. After 3 days of storage, frozen semen was thawed in water bath at 37 °C for 30 s. After glycerol removal, intravaginal Inseminations were performed at the depth of 2 and 4 cm. The no. of fertilized eggs (31.4 ± 1.6 vs. 27.7 ± 1.8), fertility rate (65.7 ± 3.6 vs. 58.8 ± 4.0), no. of hatched chicks (27.8 ± 1.9 vs. 23.5 ± 1.6), hatchability of set eggs (58.8 ± 4.3 vs. 49.7 ± 3.2) and hatchability of fertilized eggs (88.4 ± 2.8 vs. 84.3 ± 2.2) were recorded higher with intravaginal depth of 4 cm compared to 2 cm. It is concluded that intravaginal insemination at the depth of 4 cm enhances the fertility outcomes of the frozen-thawed Indian red jungle fowl semen.

Abstract
Cerebral palsy (CP) is a non- progressive disorder of movement and posture due to a lesion of the developing brain. It is the commonest physical disability in childhood that affects function and development. Neuro imaging is currently recommended as a standard evaluation in children with cerebral palsy. This hospital based cross-sectional study was conducted in Paediatric Neurology out-patient department of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from July 2015 to December 2015 to see the frequency and pattern of neuro-imaging findings in children with cerebral palsy. A total of 130 cases those who were attended and diagnosed as cerebral palsy based on history, clinical examination and neuro developmental assessment included in this study. All patients were sent to radiology & imaging department of same hospital for CT scan of brain. Among total 130 cerebral palsy patients male were more affected than female (88 boys and 42 girls) with male to female ratio 2.09: 1. Their ages ranged between 6-72 months with a mean age 25.6 months. The commonest age group was 6-24 months (46.9%). Common mode of delivery was normal vaginal delivery (62.3%) & Perinatal asphyxia (PNA) occurred in 66.9% cases. The commonest type of cerebral palsy was spastic form. Among them most cases were quadriplegic type, 64 cases (53.3%). Other cases were hemiplegic 27(20.7%) diplegic 13(10.0%). Total 84.7% had documented cerebral neuroimaging abnormalities; among them, diffuse cortical atrophy (46.9%), encephalomalacic change (19.9%), malformation (6.1%), and calcification (5.3%). CT scan was normal in 15.3% cases of cerebral palsy. The commonest co morbidity was speech delay (50%). Most of the patient with CP had abnormal CT scan finding though some patient had normal CT scan. Diffuse cerebral atrophy and encephalomalacic changes constitute frequent CT neuroimaging findings and commonly found in quadriplegic type of cerebral pulsy patients. Though diagnosis of cerebral palsy is essentially clinical, neuro imaging improves the understanding of the neuro-anatomical basis for function in CP. Etiology, type of CP and extent of motor impairments can easily be identified by the neuro imaging.

Abstract
BACKGROUND The quality of cryopreserved buffalo semen is low due to high susceptibility of sperm membranes to cold shock. OBJECTIVE The present study was designed to investigate the effect of recombinant type-III antifreeze protein from the eel pout Macrozoarces americanus (rAFPIII) on freezability of buffalo semen. MATERIALS AND METHODS Semen was collected from three buffalo bulls for three weeks (replicates). Qualified ejaculates (N=18) were split into four aliquots and diluted in Tris-citric acid extender containing 0.0, 0.1, 1 and 10 µg mL-1 of rAFPIII. Semen was cooled to 4 C, evaluated for sperm motility and PMI, cryopreserved and assessed for post-thaw quality. RESULTS Supplementation of the extender with rAFPIII didn't affect motility and PMI of chilled semen. Post-thaw sperm motility and PMI were higher in extender supplemented with rAFPIII (10µg mL-1) compared to control. Sperm viability and acrosome integrity remained the same. CONCLUSION Addition of rAFPIII in extender improved motility and PMI of cryopreserved buffalo semen.

Abstract
Diabetes mellitus is one of the leading non-communicable diseases all over the world including Bangladesh. Diabetes is characterized by chronic hyperglycemia and disturbances of carbohydrate, lipid and protein metabolism. Glycated hemoglobin (HbA1c) level of ≥6.5% has been included as a criterion for diagnosis of diabetes. Impaired lipid profile is commonly present in type 2 diabetes. Aim of the study was to investigate the association between serum lipid profile and blood glucose. And hypothesizing that early detection of lipid abnormalities and treatment can minimize the risk for atherogenic cardiovascular disorder and cerebrovascular calamity in patients with type 2 diabetes mellitus (T2DM). This observational cross sectional study was carried out in the department of Biochemistry, Bangladesh Institute of Research & Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) hospital, Dhaka, Bangladesh from January 2016 to June 2016. A total 105 patients with T2DM of age within the range of 30-45 years were selected for the purpose. Fasting blood glucose (FBG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and glycated haemoglobin (HbA1c) levels were evaluated. Test of significance was calculated by unpaired Student's 't' test. Correlation studies (Pearson's correlation) were performed between glycated haemoglobin (HbA1c) and serum lipid profile. Significance was set at p<0.05. Significantly higher mean serum levels of TC, TG and LDL-C and significantly lower mean serum levels of HDL-C were noted in patients with diabetes. Significant correlations were observed between HbA1c value and serum levels of TC, TG and HDL-C (p<0.05) but no significant correlation of HbA1c value with LDL-C in-diabetes patient. The study concluded that HbA1c value correlate well with lipid profile in-diabetes patients. So, HbA1c can be used as a predictor of dyslipidemia in type 2 diabetes.

Abstract
Several mechanisms have been proposed to explain the symptoms of functional dyspepsia but actual pathogenesis is still poorly understood. Recent studies support duodenal abnormality to be the most important causal link to explain symptoms and to understand abnormal pathophysiology of functional dyspepsia. The aim of this prospective observational study is to compare eosinophil count in duodenal mucosa between patients with functional dyspepsia and control subjects without dyspepsia and was done at the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. Total 42 patients of functional dyspepsia based on Bangla validated version of ROME III criteria and 42 controls who were referred for upper gastrointestinal endoscopy for reasons other than dyspepsia were included. Biopsy specimens were collected from the second part (D2) of the duodenum of all participants. Eosinophil count was quantitatively evaluated by hematoxylin and eosin staining and expressed in numbers per 5 HPF. Significantly increased duodenal eosinophil count was found in functional dyspepsia group than non dyspeptic patients (22.78±08.78 vs. 14.90±10.70, p=0.001). Higher duodenal eosinophil count was found in patients with postprandial distress syndrome. Increased duodenal eosinophil count was found in patient of functional dyspepsia. It requires further large scale multicenter studies to establish duodenal eosinophilia as a biomarker of functional dyspepsia.

Abstract
Levetiracetam has been introduced for the control of seizures besides phenobarbital as monotherapy in children with epilepsy. This study was aimed to compare the effectiveness of these two drugs for the control of seizures in epilepsy. This randomized controlled trial was done to assess the efficacy and tolerability of levetiracetam compared to phenobarbital in childhood epilepsy and was conducted in Institute of Pediatric Neurodisorder and Autism (IPNA), Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh among children between 1 month to 15 years who were diagnosed as cases of epilepsy (idiopathic focal, generalized, focal with secondary generalization) according to ILAE to assess the effect of Levetiracetam (n=50) and Phenobarbital (n=68) from May 2015 to July 2016. The children were followed up for 12 months at 3 months interval to compare the seizure remission and side effects of Levetiracetam and Phenobarbital. The children in levetiracetam group was about 10 months older along with older age of onset of seizure (p=0.02) than those of phenobarbital group (p=0.03 and 0.02 respectively). GTCS was the most common type of seizure in both groups. During 3 months of intervention 55.8% patients of levetiracetam group achieved 50-75% seizure remission compared to 44.2% in phenobarbital group, at 6 months period 75-100% seizure remission observed among 57.4% patients of levetiracetam group compared to 42.6% of phenobarbital group (p=0.06), which continued to increase at 9 months in levetiracetam (n=33, 55.9%) compared to phenobarbital (n=26, 44.1%) and this value is statistically significant (p=0.05). No further improvement observed at 12 months follow up. Behavioral problem was reported among 4 patients of phenobarbital group without any evidence of cognitive deterioration, only 3 patients of levetiracetam experienced irritability, but no children of both group discontinued treatment due to side effects. Levetiracetam mono-therapy is more effective in controlling seizures in focal, generalized and focal with secondary generalization epilepsy compared to phenobarbital with minimum side effects.

Abstract
Stroke is defined by abrupt onset of neurologic deficit that is attributable to a focal vascular cause. The clinical manifestations of stroke are highly variable because of the complex anatomy of the brain and its vasculature. Ischaemic cerebrovascular disease accounts for a substantial proportion of all stroke although the proximate cause of most brain infarcts is thrombus formation, atherosclerosis is the chief underlying cause. Elevated blood level of C-reactive protein (CRP) is associated with an increased risk of atherosclerotic vascular disease including stroke. This descriptive, cross sectional study was carried out in the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from January 2016 to June 2017 among purposively selected sixty one patients following inclusion and exclusion criteria with a view to estimate the C-reactive protein level among stroke patients. Data were collected through interview, physical examinations and laboratory investigations. Collected data were checked for consistency and completeness. Statistical analysis was performed using SPSS version 17.00 for windows. Most (27.87%) of the patients were in age group 69-79 years. Majority (80.33%) were male. A good number (63.90%) of patients were illiterate. An overwhelming number (90.16%) of patients came from rural area and most (54.10%) were farmers. Significant number (68.86%) of patients came within 10 hours of attack. Majority of the patients (68.85%) had C-reactive protein level raised from base line and had statistical association with acute ischemic stroke. Most (80.95%) of patients with ischaemic stroke had raised level of CRP which was statistically significant. Elevation of CRP in more common in ischaemic stroke than haemorrhagic stroke.

Abstract
Egg yolk is a good external cryoprotectant of mammalian sperm and some wild bird's sperm, but, at least in domestic breeds of chicken (Gallus gallus domesticus), it may inhibit eventual fertilization of ova when high concentrations are used. We hypothesized that egg yolk can protect the sperm from cryo-induced damages providing adequate fertilization in one phylogenetic wild ancestor of current chicken breeds: the Indian red jungle fowl (Gallus gallus murghi). To test the hypothesis, the present study was designed to evaluate different concentrations of egg yolk in extender in comparison with glycerol. Semen collected from Indian red jungle fowl cocks (n = 8) was cryopreserved using different egg yolk concentrations (10%, 15%, 20% and 25%) or 20% glycerol (control group) following routine protocol of cryopreservation. During cryopreservation, sperm motility (67.5 ± 2.5%), plasma membrane integrity (66.3 ± 2.4%), viability (58.8 ± 1.3%) and acrosomal integrity (60.0.8 ± 2.0%) were recorded highest in an extender with 15% egg yolk compared to other experimental extenders and control at post-dilution, cooling, equilibration and thawing. The no. of fertilized eggs (26.6 ± 0.7, 21.6 ± 1.2), percent fertility (55.9 ± 4.4, 46.5 ± 2.2), no. of hatched chicks (23.6 ± 1.0, 17.2 ± 1.0), percent hatch (49.5 ± 3.2, 37.1 ± 2.5%) and hatchability of the fertile eggs (89.4 ± 2.2, 79.7 ± 3.7) were recorded higher (P < 0.05) with semen cryopreserved with 15% egg yolk compared to control (20% glycerol). It is concluded that 15% egg yolk can be used in cryopreservation protocol of Indian red jungle fowl sperm.
