ABSTRACT
CatSper1 and TNP2 genes are known to affect semen quality and fertility parameters, including sperm motility and maturation. However, studies are yet to examine the genes in indigenous and crossbred cattle in Bangladesh. Therefore, this study was conducted to determine the genetic variants of CatSper1 and TNP2 in indigenous and crossbred cattle in Bangladesh. Blood samples were collected from 130 indigenous and 70 crossbred (Holstein Friesian × indigenous) cattle. Nucleotide variation was evaluated by PCR-RFLP and sequencing. The results of the study showed that the indigenous cattle possessed only TT genotype (1.0), whereas the crossbreds possessed both TT (0.91) and CT (0.09) genotypes, which was validated by gene sequencing. Additionally, the CatSper1 was conserved in both the indigenous and crossbred cattle, suggesting good semen quality and fertility. However, the TNP2 was conserved in the indigenous breeds and mostly conserved in the crossbreds. The findings of this study reveal the diversity of CatSper1 and TNP2 genes in indigenous and crossbred cattle.

OBJECTIVES: Early sexual initiation (ESI), defined as sexual activity that begins before 15 or 18 years of age, is one of the risky sexual behaviours that has been linked to increased likelihood of adverse consequences, such as sexually transmitted diseases, unintended pregnancies and unsafe abortions. However, to date, there are no studies investigating the prevalence and factors influencing ESI among adolescent females (aged 10-19 years) in Bangladesh. Thus, this study aimed to identify the potential determinants of ESI among adolescent females in Bangladesh based on data that are representative of the country. STUDY DESIGN: This was a cross-sectional study. METHODS: Based on the availability of the data, the analysis included a weighted sample of 2051 adolescent females aged 15-19 years from the Bangladesh Demographic and Health Survey 2017/18. Initial selection of predictor variables was based on the bivariate analysis using the Chi-squared test. Univariate and multivariable logistic regression modelling were performed to measure the crude and adjusted effect of the selected predictor variables on ESI using the odds ratio (OR). The elasticity of the effects was calculated by their 95% confidence intervals (CIs). RESULTS: Approximately 22% and 85% of female adolescents experienced ESI before the age of 15 and 18 years, respectively. Findings revealed that illiteracy (adjusted OR [AOR]: 3.61, 95% CI: 1.82-7.18), primary education (AOR: 2.08, 95% CI: 1.60-2.69), working status (AOR: 1.25, 95% CI: 0.98-1.60), living in Chittagong (AOR: 0.46, 95% CI: 0.27-0.79), living in Sylhet (AOR: 0.21, 95% CI: 0.08-0.56), reading newspapers (AOR: 0.63, 95% CI: 0.40-1.01), earlier marriage preference (AOR: 3.30, 95% CI: 2.31-4.71) and later marriage preference (AOR: 4.10, 95% CI: 3.01-5.59) were significantly linked with ESI before the age of 15 years. ESI before the age of 18 years was significantly association with primary education (AOR: 1.47, 95% CI: 1.01-2.13), religion (AOR: 0.55, 95% CI: 0.32-0.94), female household head (AOR: 1.93, 95% CI: 1.17-3.19), living in Rajshahi (AOR: 1.97, 95% CI: 0.95-4.08), being in the 'poorest' wealth category (AOR: 2.43, 95% CI: 1.45-4.07), being in the 'poorer' wealth category (AOR: 1.70, 95% CI: 1.06-2.72), being in the 'middle' wealth category (AOR: 1.76, 95% CI: 1.12-2.77), being in the 'richer' wealth category (AOR: 1.58, 95% CI: 1.02-2.44), earlier marriage preference (AOR: 15.71, 95% CI: 9.09-27.14), later marriage preference (AOR: 12.62, 95% CI: 8.82-18.06) and heard about family planning (AOR: 0.70, 95% CI: 0.47-1.04). CONCLUSIONS: In Bangladesh, the prevalence of ESI among female adolescents is a public health concern. Due to the detrimental impact of ESI on the well-being of adolescents, it is crucial that policymakers consider the factors influencing ESI that have been identified in this study when designing health strategies. The findings from this study will help the development of evidence-based effective initiatives by policymakers in collaboration with governmental and non-governmental organisations.

LaIr3Ga2 is a kagome superconductor with a superconducting temperature (Tc) of 5.16 K. Here, we present the physical properties of the LaIr3Ga2 kagome superconductor computed via the DFT method wherein six different exchange-correlation functionals were used. The lattice parameters obtained using different functionals are reasonable, with a slight variation compared to experimental values. The bonding nature was explored. The elastic constants (Cij), moduli (B, G, Y), and Vickers hardness (Hv) were computed to disclose the mechanical behavior. The Hv values were estimated to be 2.56-3.16 GPa using various exchange-correlation functionals, indicating the softness of the kagome material. The Pugh ratio, Poisson's ratio, and Cauchy pressure revealed the ductile nature. In addition, mechanical stability was ensured based on the estimated elastic constants. The anisotropic mechanical behavior was confirmed via different anisotropic indices. The Debye temperature (ΘD), melting temperature (Tm), and minimum thermal conductivity (kmin) were calculated to characterize the thermal properties and predict the potential of LaIr3Ga2 as a thermal barrier coating material. The electronic density of states was investigated in detail. The McMillan equation was used to estimate Tc, and the electron-phonon coupling constant (λ) was calculated to explore the superconducting nature. The important optical constants were also calculated to explore its possible optoelectronic applications. The values of reflectivity in the IR-visible region are about 62% to 80%, indicating that the compound under study is suitable as a coating to reduce solar heating. The obtained parameters were compared with previously reported parameters, where available.
ABSTRACT
The study was conducted to determine the genetic variants of κ-casein and ß-lactoglobulin genes in native cattle. DNA was extracted from blood samples (n = 80) collected from Babuganj, Barishal followed by PCR with gene-specific primers. Genotyping was done by RFLP with HindIII, and HaeIII restriction enzymes. Allelic and genotypic frequencies, genetic diversity, heterozygosity and Hardy-Weinberg equilibrium were estimated using the Popgen32 software. A total 80 samples were genotyped and three genotypes, namely AA, AB and BB, were detected for both the genes. In case of κ-casein gene, higher frequency was observed for AA genotype (0.73) followed by AB (0.23) and BB (0.04) genotype. A allele (0.84) was found to dominate over B allele (0.16). For ß-lactoglobulin gene, BB genotype (0.66) was found more frequently than AB (0.18) and AA (0.16) genotypes. Highest frequency was found for B (0.75) followed by A (0.25) allele. The average genetic diversity (He) was 0.38. The result indicated differences between observed (Ho) and expected (He) heterozygosity and it was out of equilibrium genetics, assumed that selection pressure was in population. To the best of our knowledge, this is the first reported study on κ-casein and ß-lactoglobulin gene variants analysis in cattle in Bangladesh.

INTRODUCTION: Organ donation (OD) rates in Malaysia have remained suboptimal for decades. Healthcare professionals (HCPs) working in critical care areas are responsible for diagnosing brain death (BD) and initiating the OD process. Impact of their knowledge and attitudes on willingness to offer the option of OD to families of potential donors is unknown. METHODS: Knowledge and attitudes about BD, OD, and organ transplantation (OT) of critical care HCPs in a Malaysian transplant centre were studied using a validated questionnaire. Responses were analysed using multivariable analysis with willingness to offer the option of OD to families of potential donors as dependent variable. RESULTS: Age (p = 0.04), profession (doctors > nurses, p < 0.001), religion (Buddhists > others, p = 0.013) [but not ethnicity], higher knowledge scores for Brain Death Test, Brain Death Knowledge, Organ Donation and Transplantation, and overall knowledge score (p < 0.001) were associated with greater odds of offering OD to families. Belief in the reliable diagnosis of BD, confidence in explaining BD, and belief that OD will not affect religious services were significantly associated with willingness to offer OD, while HCPs who were willing to personally donate organs had greatest odds (p < 0.001). Other factors that significantly influenced HCPs' willingness to offer included their perception about families' willingness to donate, body disfigurement, and confidence in OT. CONCLUSIONS: Overall, HCPs had highly positive attitudes. However, potential barriers in offering OD to families were identified. Proven interventions from international experience could help address these issues and likely improve OD rates in Malaysia.

INTRODUCTION: Organ donation rate in Malaysia is amongst the lowest in the World. Healthcare professionals (HCPs) working in critical care areas play an important role in the deceased organ donation (DOD) process. This study seeks to identify the demographics of HCPs working in the critical care areas and their knowledge and attitudes toward the DOD process. METHOD: A cross-sectional survey on the demographics, knowledge and attitudes of the doctors and nurses working in critical care areas was undertaken by the random sampling method, using a validated, structured questionnaire. HCP's knowledge and attitudes towards brain death (BD), DOD, organ transplantation (OT), and possession of organ donor card were compared against their demographics. RESULTS: Four hundred and twelve (72.9%) out of the total 565 HCPs in critical care areas responded of whom 163 (39.6%) were doctors and 249 (60.4%) were nurses. After adjusting for other factors, department of work and profession were highly correlated with the overall knowledge score (p<0.001 and p=0.003 respectively) and knowledge about BD (p<0.001 and p=0.013 respectively). HCPs from the neurosurgical intensive care unit (p<0.001) and doctors (p<0.001) had higher mean knowledge scores compared to their counterparts. Profession was most significantly correlated with having a positive attitude towards BD (p<0.001) and OT (p<0.001). CONCLUSION: Department, profession and ethnicity were the demographic characteristics that correlated with knowledge and attitudes of HCPs on organ donation. Efforts to improve DOD rates in Malaysia should include targeted interventions to address the knowledge and attitudes of HCPs working in critical care areas.

AIMS: The aim of this study was to evaluate the antagonistic activity of halotolerant bacteria against rice brown stripe pathogen Acidovorax oryzae. METHODS AND RESULTS: Fifteen of 136 isolates of halotolerant bacteria exhibited strong in vitro and in vivo antagonistic activity against both strains of A. oryzae. The 15 antagonistic isolates were identified as 'operational group Bacillus amyloliquefaciens' based on physiological and biochemical features, fatty acid profiles as well as sequence analysis of 16S rRNA, gyrA and rpoB genes. Furthermore, this result indicated that the most effective antagonistic isolates K5-3 and PPB6 could produce siderophore in iron-limiting medium, and four kinds of secondary metabolites based on MALDI-TOF analysis. In addition, the culture filtrates of isolates K5-3 and PPB6 caused the damage of cell membrane evidenced by the TEM images, and resulted in 73-80% reduction in cell numbers, 55-65% reduction in biofilm formation, and 42-50% reduction in swimming ability of both strains of A. oryzae. CONCLUSIONS: These isolates in particular K5-3 and PPB6 of halotolerant bacteria markedly inhibited the growth of A. oryzae. SIGNIFICANCE AND IMPACT OF THE STUDY: To our knowledge, this is the first report on biological control of halotolerant bacteria against bacterial brown stripe of rice.
ABSTRACT
Currently there is no effective approach for monitoring early ß-cell loss during islet graft rejection following human islet transplantation (HIT). Due to ethical and technical constraints, it is difficult to directly study biomarkers of islet destruction in humans. Here, we established a humanized mouse model with induced human ß-cell death using adoptive lymphocyte transfer (ALT). Human islet grafts of ALT-treated mice had perigraft lymphocyte infiltration, fewer insulin+ ß cells, and increased ß-cell apoptosis. Islet-specific miR-375 was used to validate our model, and expression of miR-375 was significantly decreased in the grafts and increased in the circulation of ALT-treated mice before hyperglycemia. A NanoString expression assay was further used to profile 800 human miRNAs in the human islet grafts, and the results were validated using quantitative real-time polymerase chain reaction. We found that miR-4454 and miR-199a-5p were decreased in the human islet grafts following ALT and increased in the circulation prior to hyperglycemia. These data demonstrate that our in vivo model of induced human ß-cell destruction is a robust method for identifying and characterizing circulating biomarkers, and suggest that miR-4454 and miR-199a-5p can serve as novel biomarkers associated with early human ß-cell loss following HIT.

Post operative complications after pituitary tumour surgery vary according to procedure. There are several surgical procedures being done such as transcranial, transsphenoidal microsurgical and transsphenoidal endoscopic approaches. One of the commonest complications is diabetes insipidus (DI). Our main objective was to find out the incidence of diabetes insipidus in post operative period among patients undergoing surgical intervention for pituitary tumour in our institute. The presence of diabetes insipidus in the postoperative period was established by measuring serum Na+ concentration, hourly urine output and urinary specific gravity to find out the incidence of diabetes insipidus in postoperative period in relation to age, gender, tumour diameter, function of tumour (i.e., either hormone secreting or not) and operative procedure used for surgical resection of pituitary tumor. As it is the most common postoperative complication so, in this study we tried to find out how many of the patients develop diabetes insipidus in postoperative period following surgical resection of pituitary tumour. This cross sectional type of observational study was carried out in the department of Neurosurgery, BSMMU from May 2014 to October 2015 on 33 consecutive patients who underwent surgical intervention for pituitary tumour for the first time. Data was collected by using a data collection sheet. The incidence of diabetes insipidus was found 23.1% of patients in <30 year age group, 38.5% of patients in 31-40 year age group and 38.5% of patients in ≥40 year age group (p=0.764). In case of distribution of patients according to gender 38.5% of male and 61.5% of female developed diabetes insipidus (p=0.073). Regarding tumour size 30.8% and 69.2% of patients developed diabetes insipidus having tumour diameter <30mm and ≥30mm respectively (p=0.590). In case of operative procedure 69.2% of patients developed diabetes insipidus who was operated by transsphenoidal endoscopic approach, 23.1% and 7.7% of patients developed diabetes insipidus who underwent pituitary tumour resection through transsphenoidal microscopic approach and transcranial microscopic approach respectively (p=0.432). 17.6% of patients develop DI having functioning pituitary macroadenoma and 62.5% of patients develop DI having nonfunctioning pituitary macroadenoma. This observational study has been performed to find out the incidence of diabetes insipidus. Incidence of postoperative DI is more at or around the age of 40 years. It is slightly predominant in female. Most of the patients manifest DI in the first 24 hours of surgical intervention. Incidence of DI is low among patients having functioning pituitary macroadenoma.

Determination of age is one of the most important and vital demand in legal affairs, court and young sports, especially from 7-21 years. There is no established age determination table in our county. So we are dependent upon Galstaun, Bashu & Bashu and other European tables, which sometimes provide misinterpretation and variation of opinion. We should have our own table suitable for our nation. So, this prospective study was carried out in the Department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2010 to June 2014 (five years) to assess the general skeletal maturity. Three hundred boys and girls of known date of birth were selected on random basis from Dhaka. Ages were limited within 7 to 21 year. Every 20 person for each age group, of them 10 were male and 10 were female. To observe the bony maturity, radiographs were taken at the end of their age belongs to. Thus a growth table is to be prepared for further evaluation.

Breast cancer is the most common malignancy in women and the second most common cause of cancer-related mortality. The distinction by physical examination of physiologic nodularity from abnormal masses can be difficult, while the clinical differentiation of a malignant mass from a benign one is difficult; the medical as well as potential legal consequences of missing a palpable carcinoma are high. There are significant number of reported cases of false-negative findings on mammography and the great desire not to miss a malignant lesion in the early stage of disease lead to aggressive biopsy, but the biopsy rate for cancer is only 10.0% to 30.0%. This means that 70.0% to 90.0% of breast biopsies are performed for benign diseases, which induce unnecessary patients discomfort and anxiety in addition to increasing costs to the patient. Clearly, there is a great need for development of additional reliable methods to complement the existing diagnostic procedures to avoid unnecessary biopsy. This cross sectional study was carried out on 43 patients having palpable breast mass, attended in the Department of Radiology and Imaging Mymensingh Medical College Hospital, Mymensingh from 1st January 2012 to 31st December 2013 for the period of two year. These patients were evaluated by USG at the Department of Radiology and Imaging and histopathological examination at the Department of Pathology of the same College to confirm the diagnosis. In diagnosis of malignant mass by USG, 9(20.9%) cases were diagnosed as malignant and 34(79.1%) cases as other than malignant. Eight out of 9 were sonographically diagnosed as malignant lesions also proved as malignant lesion by histopathology and 1 other than malignant. Out of 34 sonographically diagnosed cases of other than malignant lesions 32 were proved histopathologically and 2 did not match with sonographic findings. USG, in diagnosis of malignant lesion, sensitivity was 80.0%, specificity 96.97%, positive predictive value (PPV) (88.89%), negative predictive value 94.12% and accuracy was 93.02% and comparable to other study. In diagnosis of benign lesion by USG, sensitivity was 96.97%, specificity 80.0%, positive predictive value (PPV) (94.12%), negative predictive value 88.89% and accuracy was 93.02%. So, USG is an appropriate imaging method for diagnosis & differential diagnosis of palpable breast mass.

Since well water utilized for domestic purposes in the Red River Delta of North Vietnam has been reported to be polluted by arsenic, barium, iron, and manganese, household sand filters consisting of various components are used. Information regarding the effectiveness of various sand filters for removal of the four toxic elements in well water is limited. In this study, arsenic levels in 13/20 of well water samples and 1/7 of tap water samples exceeded World Health Organization (WHO) health-based guideline value for drinking water. Moreover, 2/20, 6/20, and 4/20 of well water samples had levels exceeding the present and previous guideline levels for barium, iron, and manganese, respectively. Levels of iron and manganese, but not arsenic, in well water treated by sand filters were lower than those in untreated water, although previous studies showed that sand filters removed all of those elements from water. A low ratio of iron/arsenic in well water may not be sufficient for efficient removal of arsenic from household sand filters. The levels of barium in well water treated by sand filters, especially a filter composed of sand and charcoal, were significantly lower than those in untreated water. Thus, we demonstrated characteristics of sand filters in North Vietnam.

This study was conducted to evaluate the effect of dietary fenugreek seed extract (FSE) on growth performance, apparent total tract digestibility (ATTD), diarrhoea scores, blood profiles, faecal microflora and faecal gas emission in weanling pigs. A total of 135 weanling pigs [(Yorkshire × Landrace) × Duroc] with an average BW of (7.96 ± 1.03 kg; 28 days of age) were used in a 42-day study. Piglets were randomly allotted to three experimental diets with nine replicate pens and five pigs per pen. Dietary treatments were as follows: CON, basal diet; FSE1, basal diet + 0.1% FSE; FSE2, basal diet + 0.2% FSE. Pigs were fed with phase 1 (0-14 days) and phase 2 (14-42 days) diets in the form of mash. Average daily gain (ADG) was linearly increased (p = 0.031) by FSE supplementation compared with CON diet during days 0-14. From days 14-42, FSE2 diet had increased ADG and growth efficiency (G/F) compared with the CON diet (p = 0.014 and 0.026 respectively). Moreover, ADG and G/F were increased by FSE supplementation during days 0-42 (linear, p = 0.037 and 0.014 respectively). Energy digestibility was higher (linear, p = 0.030) by FSE supplementation at 6 weeks. On day 42, dietary supplementation of FSE linearly increased red blood cells (RBC) and immunoglobulin G (IgG) concentration (p = 0.042 and 0.038 respectively). Piglets fed FSE2 diet had higher (linear, p = 0.025) serum high-density lipoprotein cholesterol (HDL-C) concentration compared with those fed CON diet. However, piglets fed FSE2 diet had linearly reduced faecal ammonia (NH3 ) and hydrogen sulphide (H2 S) gas emission compared with those fed the CON diet (p = 0.018 and 0.010 respectively). In conclusion, FSE supplementation increased the performance and reduced faecal gas emission in weanling pigs.

To evaluate the biochemical parameters of metabolic syndrome in case of acute myocardial infarction (AMI) patients this case control study was carried out in the department of Biochemistry, Mymensingh Medical College in collaboration with Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2012 to June 2013. To assess of serum total cholesterol, triacylglycerol, HDL-cholesterol, LDL-cholesterol, to estimate of serum glucose and to establish the association of age, sex, BMI, waist circumference, waist hip ratio and blood pressure of myocardial infarction patients. A total of 120 subjects were included in the study. Among them 60 were subjects of AMI cases and another 60 subjects of non AMI patients as controls. Serum total cholesterol, serum triacylglycerol, serum LDL-Cholesterol & serum HDL-Cholesterol were estimated in each sample. All values were expressed as Mean±SD. Statistical significance of difference between case and control were evaluated by using student's unpaired 't' test. All statistical analysis was done by using SPSS windows package. Past history of diabetes Mellitus and hypertension were more common in cases compared to those in control (p<0.001) which was statistically highly significant. There was no significant difference in the history of smoking between case and control. Statistical mean values of serum triacylglycerol, serum FBS, serum total cholesterol were highly significant in AMI patients in comparison to control (p<0.001). Statistical mean value of HDL-C was significantly decreased in AMI patients in contrast to control (p<0.001). In this study systolic blood pressure and diastolic blood pressure were significantly increased in AMI patients in comparison to control (p<0.05). Waist circumference was highly significant in AMI patients in comparison to control (p<0.001). Analyzing the findings of the present study there were significant alteration in lipid profile, blood pressure, fasting blood sugar & WC. These findings reaffirm the clinical importance of the metabolic syndrome as a significant risk factor for AMI. So it may be recommended that estimation of these parameters may help pivotal for better management of AMI.

In the present study serum glucose were estimated in pregnant women during the first trimester of pregnancy and third trimester of pregnancy to observe the frequency of hyperglycemia during pregnancy and to assess the incidence of gestational diabetes mellitus. This study was a cross sectional study, carried out in the Department of Physiology of Mymensingh Medical College, Mymensingh from July 2014 to June 2015. For this purpose, total 300 women with age ranged from 18 to 35 years were selected and divided into 100 healthy non pregnant women as control group and 200 normal pregnant women as study group. Study group was further divided into 100 pregnant women in first trimester of pregnancy and 100 pregnant women in third trimester of pregnancy. Diagnosed case of type I and type II diabetes, hypothyroidism, cushing's syndrome, polycystic ovary, antipsychotic drug users, regular steroid users were excluded from this study. Serum glucose was evaluated by the glucose-oxidase principle by GOD-PAP method in women with 1st trimester of pregnancy, 3rd trimester of pregnancy and in non pregnant women. Statistical analysis of data was done by unpaired student's t test. The results showed that the serum glucose levels increased significantly in third trimester and the value is not significant in first trimester. The increasing frequency of serum glucose level in third trimester may predispose the women to hyperglycemia of pregnancy or gestational diabetes mellitus.

This cross sectional study was conducted to evaluate the role of doppler ultrasonography of hepatic venous waves for evaluation of large varices in cirrhotic patients from July 2013 to June 2015 in Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Patients getting admitted in the ward with a diagnosis of cirrhosis were enrolled in the study and purposive sampling technique was adopted. The sample size was 43. Data were collected by face to face interview and some data were gathered by records review and analyzed with the help of SPSS windows version - 12 software programs. Statistical significance was set at P<0.05 and confidence interval set at 95%. The research protocol was approved by the local ethical committee. Esophagogastroduodenoscopy is the gold standard for the diagnosis of esophageal varices. If the gold standard is not available, other possible diagnostic steps would be Doppler ultrasonography of the blood circulation (not endoscopic ultrasonography). Although and it can certainly demonstrate the presence of varices. In 60.47% of patient's monophasic wave pattern was seen and in 39.53% of cases biphasic & triphasic wave pattern were detected. Endoscopic examination was performed in all selected patients. In this study, 67.44% is large varices, 32.66% is small varices. Chi Square test was done for hypothesis testing and it was found significant (<0.05) and it indicates monophasic wave in Doppler USG signifies large varices. This test was also done to find out whether any significant difference of hepatic venous waveform in between male and female but it was not significant (>0.05). Diagnostic performance of USG for evaluation of varices showed, Sensitivity: 86.2%, Specificity: 92.85%, PPV: 96%, NPV: 76.47%, Accuracy 88%. Correlation co-efficient was 0.0064 which indicates moderately positive correlation in between monophasic hepatic venous waveform pattern by Doppler USG and large varices in oesophagogastroduodenoscopic findings Normal hepatic wave form shows triphasic pattern. Loss of this pattern in cirrhosis is mainly due to loss of compliance of liver. In conclusion, the loss of triphasic pattern of hepatic wave form is highly sensitive in predicting the presence of large varices in cirrhotic patients and this doppler parameter may be used as a non-invasive test for cirrhotic patients, who wish to avoid upper GI endoscopy. Further studies using a combination of various doppler parameters are needed to create indices with a better predictive value.

The objective of the study was to find out correlation between umbilical cord diameter, cross sectional area with gestational age and foetal anthropometric parameters. This cross sectional study was conducted among healthy women between the 24(th) and 40(th) completed weeks of a normal pregnancy in the Department of Radiology & Imaging, Mymensingh Medical College Hospital, Mymensingh during the study period, from July 2009 to June 2011. A total of 230 consecutive normal pregnancy patients were included in the study. The diameter & cross-sectional area of the umbilical cord were measured on a plane adjacent to the junction of the umbilical cord and the fetal abdomen, in cross-section, with maximum magnification of the image. The cord was manually circled, and it's cross sectional areas was automatically calculated by the ultrasonograph. The mean±SD age was 24.3±4.7 years with range from 19 to 36 years. The mean gestational age was 32.1±4.5 weeks and more than a half (56.4%) of the pregnant women were nulliparas. A positive significant (p<0.001) correlation were found between umbilical cord diameter with bi-parietal diameter (r=0.548); head circumference (r=0.411); abdominal circumference (r=0.444); femur length (r=0.366) and gestational age gestation age (r=0.643). Similarly, a significant (p<0.001) positive week correlation were found between umbilical cross sectional area with bi-parietal diameter (r=0.3303); head circumference (r=0.3202); abdominal circumference (r=0.2651); femur length (r=0.3307) and gestation age (r=0.4051). A positive significant better correlation was found with umbilical cord diameter than cross sectional area with foetal anthropometric parameters.

The dopamine transporter is a key protein responsible for regulating dopamine homeostasis. Its function is to transport dopamine from the extracellular space into the presynaptic neuron. Studies have suggested that accumulation of dopamine in the cytosol can trigger oxidative stress and neurotoxicity. Previously, ectopic expression of the dopamine transporter was shown to cause damage in non-dopaminergic neurons due to their inability to handle cytosolic dopamine. However, it is unknown whether increasing dopamine transporter activity will be detrimental to dopamine neurons that are inherently capable of storing and degrading dopamine. To address this issue, we characterized transgenic mice that over-express the dopamine transporter selectively in dopamine neurons. We report that dopamine transporter over-expressing (DAT-tg) mice display spontaneous loss of midbrain dopamine neurons that is accompanied by increases in oxidative stress markers, 5-S-cysteinyl-dopamine and 5-S-cysteinyl-DOPAC. In addition, metabolite-to-dopamine ratios are increased and VMAT2 protein expression is decreased in the striatum of these animals. Furthermore, DAT-tg mice also show fine motor deficits on challenging beam traversal that are reversed with l-DOPA treatment. Collectively, our findings demonstrate that even in neurons that routinely handle dopamine, increased uptake of this neurotransmitter through the dopamine transporter results in oxidative damage, neuronal loss and l-DOPA reversible motor deficits. In addition, DAT over-expressing animals are highly sensitive to MPTP-induced neurotoxicity. The effects of increased dopamine uptake in these transgenic mice could shed light on the unique vulnerability of dopamine neurons in Parkinson's disease.

This paper reviews less well-known or less widely distributed viruses of the Bunyaviridae family that are nonetheless of significant veterinary and public health concern. These include: Cache Valley fever, Main Drain, Ingwavuma, Bhanja and Heartland viruses. A description of the agents, clinical signs of infection, epidemiology, and insect transmission is provided for each, and the authors discuss current diagnostic strategies plus the lack of control measures.
