Relationship between Body Mass Index and Serum Alanine Transaminase Concentration in Obese Female.

The serum Alanine Transaminase (ALT) activity has been regarded as a reliable and sensitive marker of liver disease. In the context of obesity ALT may also be a good indicator of overall health. Obesity has been reported as a risk factor associated with elevation of ALT, which is a surrogate marker of Non-alcoholic fatty liver disease (NAFLD). Elevated ALT may correlate with the severity of NAFLD in obese female. This study was done to evaluate the changes of serum ALT in obese female age ranged 30-60 years in comparison to normal healthy female of same age. At the same time we can know the relationship between body mass index and serum ALT concentration in obese female. This analytical cross-sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from January 2020 to December 2020. A total number of 100 female subjects were included in this study. Among them fifty (50) normal healthy female were taken as control group (Group I) and fifty (50) obese female were taken as study group (Group II). The level of serum ALT was determined by Ultra violet (UV) method. Data were expressed as mean±SD and statistical significance of difference among the group was calculated by unpaired Student's 't' test. Pearson's correlation coefficient test was done to find the correlation of serum ALT with BMI by using SPSS (version 21.0). During interpretation of results, p values of <0.001 were considered as statistically highly significant. In this study, serum level of ALT was significantly higher (p<0.001) in obese female compared to those of healthy control female. In addition, there is a positive correlation of serum ALT with BMI. From the results of the present study, it can be concluded that, elevated ALT was significantly associated with high BMI as well as with other feature of NAFLD.

Level of Serum Creatinine and Creatinine Clearance Rate in Obese Female.

The prevalence of obesity continues to increase worldwide day by day causing a serious health problem and impose a significant impact on the National Health Service (NHS) budget. Obesity usually arises from the interactions of multiple genes and lifestyle factors. This study was done to evaluate changes of serum creatinine and creatinine clearance rate in obese female age ranged 30-60 years in comparison to normal healthy female of same age. This study, a cross-sectional analytical type, was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh between the period from January 2020 to December 2020. A total number of 100 female subjects were included in this study. Among them fifty (50) normal healthy female were taken as control group (Group I) and fifty (50) obese female were taken as study group (Group II). To see the level of serum creatinine determined by Kinetic Colorimetric method and creatinine clearance rate was calculated from serum creatinine by Cockcroft-Gault equation. Data was calculated by unpaired Student's't' test and were expressed as mean (±SD). Pearson's correlation coefficient test was done to find the correlation of serum creatinine and creatinine clearance rate with BMI. In this study we found that mean serum Creatinine and Creatinine clearance rate were higher in obese female in comparison to normal healthy female. Again, serum Creatinine and Creatinine clearance rate were positively correlated with BMI. Therefore, to prevent obesity related complications and leading a healthy life we suggest estimations of these parameters routinely.

Thermodynamic analysis of fuels in gas phase: ethanol, gasoline and ethanol - gasoline predicted by DFT method.

This paper presents a theoretical study using density functional theory to calculate thermodynamics properties of major molecules compounds at gas phase of fuels like gasoline, ethanol, and gasoline-ethanol mixture in thermal equilibrium on temperature range up to 1500 K. We simulated a composition of gasoline mixture with ethanol for a thorough study of thermal energy, enthalpy, Gibbs free energy, entropy, heat capacity at constant pressure with respect to temperature in order to study the influence caused by ethanol as an additive to gasoline. We used semi-empirical computational methods as well in order to know the efficiency of other methods to simulate fuels through this methodology. In addition, the ethanol influence through the changes in percentage fractions of chemical energy released in combustion reaction and the variations on thermal properties for autoignition temperatures of fuels was analyzed. We verified how ethanol reduces the chemical energy released by gasoline combustion and how at low temperatures the gas phase fuels in thermal equilibrium have similar thermodynamic behavior. Theoretical results were compared with experimental data, when available, and showed agreement. Graphical Abstract Thermodynamic analysis of fuels in gas phase.

Sixty years old man with primary cutaneous lymphoma.

Cutaneous lymphomas are uncommon skin tumors. Which may be primary or secondary and T-cell or B-cell according to cell type the former type being less frequent. The term "primary cutaneous lymphoma" refers to cutaneous lymphomas that present in the skin with no evidence of extracutaneous disease at the time of diagnosis. In this report, we describe a 60-year-old man with primary cutaneous lymphoma, who presented with multiple painless reddish nodular skin lesion on the different sites of his body and there was no evidence of systemic involvement.

Peginterferon α-2a and rivabirin in the treatment of chronic hepatitis C.

Peginterferon α-2a with ribavirin produces significantly higher sustained virological response (SVR) in comparison to conventional interferon monotherapy in patients with chronic hepatitis C virus (HCV) infection. We evaluated the efficacy and safety of peginterferon α-2a plus ribavirin combination in the treatment of chronic hepatitis C among Bangladeshi patients. A total of 64 patients were randomly selected in this study and were assigned for treatment with peginterferon α-2a 180µg once weekly plus ribavirin daily for 24 weeks in case of genotypes 2 and 3 infections and 48 weeks in case of genotypes 1 and 4 infections. Ribavirin was given 800mg in divided doses in case of genotypes 2 and 3 infections and 1000mg-1200 mg in case of genotypes 1 and 4 infections according to body weight daily(1000 mg in divided doses if body weight <75kg and 1200mg in divided doses if body weight >75kg). Efficacy was assessed by measurements of serum HCV-RNA and serum ALT. A higher proportion of patients (71.87%) who received peginterferon α-2a plus ribavirin had a sustained virological response. It is observed that genotype 3 (a and b) patients showed poor response (SVR-47.05%), where as genotypes 1(a,b), 3 and 4 mixed, 2b and 4 infections showed response rate of 100%. So it can be concluded that once weekly peginterferon α-2a plus daily ribavirin is effective in chronic HCV infection in Bangladesh and overall response rate is similar to that reported in other studies.

Risk factors of non-alcoholic fatty liver disease.

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

Na+-driven multidrug efflux pump VcmA from Vibrio cholerae non-O1, a non-halophilic bacterium.

A chromosomal DNA fragment from Vibrio cholerae non-O1 containing a drug resistance determinant was cloned and sequenced. The deduced amino acid sequence suggested that the determinant gene encodes a multidrug efflux pump. We designated the pump VcmA. Escherichia coli cells transformed with a plasmid carrying the vcmA gene showed increased resistance against norfloxacin, ciprofloxacin, ofloxacin, daunomycin, doxorubicin, streptomycin, kanamycin, ethidium bromide, 4',6-diamidino-2-phenylindole dihydrochloride, Hoechst 33342 and acriflavine. Na+ (or Li+)-dependent efflux of ethidium bromide was detected in transformant cells. Efflux of Na+, elicited by ethidium bromide, was observed from transformant cells. Thus, we concluded that the VcmA is a Na+/drug antiporter.

An N-terminal region of LukF of staphylococcal leukocidin/gamma-hemolysin crucial for the biological activity of the toxin.

The two staphylococcal bi-component toxins, leukocidin and gamma-hemolysin share LukF [Kamio et al, FEBS Lett., 321, 15-18 (1993)]. This report identifies the pivotal amino acid residues in the N-terminal region of LukF for the leukocytolytic and hemolytic activities in the presence of LukS and HIg2, respectively, measuring the toxin activity of a series of LukF mutants with truncated N-terminals. The data obtained showed that the LukF mutant TF21, lacking 20 amino acid residues at the N-terminus of LukF, failed to have any hemolytic activity and had less 10% leukocytolytic activity than that of the intact LukF, while 16-residue truncations retained both toxin activities without loss. The LukF mutants lacking 18- through 19-residue segments from the N-terminus showed low toxin activity on both target cells. All mutants having no toxin activity were also not capable of binding to the human erythrocytes. It can thus be concluded that the 3-residue segment, L18Y19K20 of LukF is crucial for the biological activity of the toxin.

Discontinuation of breast-feeding during episodes of diarrhoea in rural Bangladeshi children.

Discontinuation of breast-feeding during an episode of childhood diarrhoea is widely regarded as a common, high-risk practice in the developing world. We studied cessation of breast-feeding in a rural Bangladeshi population under comprehensive surveillance for medically treated diarrhoeal episodes. Among 2129 episodes in children aged under 36 months and breast-fed before the onset of diarrhoea, there were only 33 (2%) in whom breast-feeding had stopped before presentation for care. Children in whom breast-feeding had stopped (cases) differed little from those in whom it had not (controls) in respect to exclusive vs partial breast-feeding, age, gender, or several maternal characteristics (maternal age, education, and recent maternal diarrhoeal illness). In contrast, cases were more likely to have presented with clinically severe illness or to have died within 30 d of presentation (odds ratio = 2.20, P less than 0.05). We conclude that discontinuation of breast-feeding during diarrhoea is an infrequent phenomenon in this population. However, the association of cessation of breast-feeding with severe clinical outcomes may be of considerable importance, particularly in countries where discontinuation of breast-feeding is more common.
