To investigate the antihyperglycemic and hypolipidemic effects of methanolic extract of leaves of Amaranthus viridis (MEAV) in normal and Streptozotocin (STZ) induced diabetic rats. The anti-hyperglycemic and hypolipidemic activity of methanolic extract of leaves of Amaranthus viridis was evaluated by using normal and STZ induced diabetic rats at dose of 200 mg/kg and 400 mg/kg by mouth per day for 21 days. Blood glucose levels and body weight was monitored at specific intervals, and different biochemical parameters, serum cholesterol, serum triglyceride, high density lipoprotein, low density lipoprotein, very low density lipoprotein were also assessed in the experimental animals. Histology of pancreas was performed. The statistical data indicated a significant increase in the body weight, decrease in the blood glucose, total cholesterol and serum triglycerides after treatment with MEAV. High density lipoprotein (HDL) cholesterol level was significantly increased when treated with extract. Histologically, focal necrosis was observed in the diabetic rat pancreas; however, was less obvious in treated groups. The MEAV has beneficial effects in reducing the elevated blood glucose level and body weight changes, and improves the lipid profile of STZ induced rats.

Background: Electrocardiography (ECG) remains an excellent screening tool for cardiac assessment in Duchenne muscular dystrophy (DMD), but an accurate interpretation requires comparison with age-matched healthy controls. Objective: We examined various ECG parameters in children with DMD, in comparison with age-matched controls. Methods: Standard 12-lead ECG tracings of serial patients were screened for quality and selected. Controls were healthy, age-matched school-going children. Both quantitative and qualitative ECG parameters were analyzed. Results: After screening, ECGs from 252 patients with DMD (8.32 ± 3.12 years, 2-21 years) and ECGs from 151 age-matched healthy controls (9.72 ± 2.23, 4-19 years) were included. A significantly higher heart rate, shorter R-R interval, and taller R wave in V1 were seen across all age group of DMD in comparison to controls, with the difference increasing with age. While QT prolongation was seen in all age groups of DMD, QTc prolongation was seen only at 10 years or more. Incomplete right bundle branch block (RBBB) and pathological Q waves in inferolateral leads were exclusive in DMD, with the latter declining with age. Evidence for left ventricular (LV) pathology, such as tall R in V5/V6, increase in SV1 + RV6 height, and QRS complex duration, were seen only in the age group of 10 years or more. Conclusion: Stratification based on age and comparison with age-matched healthy subjects showed that several ECG parameters were influenced by age, and it also identified age-dependent evidence for LV pathology and QTc prolongation in DMD.

AIM: Inflammation plays a lead role in the tumor microenvironment and promotes metastasis. Single-nucleotide polymorphism (SNP) in the tumor necrosis factor (TNF) gene locus may alter the expression of genes and proteins. The objective of the study is to find the distribution of genetic polymorphism in the sites of TNF-α −308G>A and TNF- β +252A>G in breast cancer and evaluate polymorphism effects on plasma levels. MATERIALS AND METHODS: The study group consisted of 109 invasive ductal primary breast cancer patients and 75 age-matched healthy female controls. Plasma cytokine concentrations were measured by the MILLIPLEX® MAP Human Cytokine/Chemokine Panel magnetic bead kits. The genotyping procedure for SNP included allele-specific polymerase chain reaction for TNFα and restriction fragment length polymorphism for TNFβ. RESULTS: Odds ratio with 95% confidence interval showed that these polymorphisms were not a causative risk factor, and both polymorphisms were consistent with Hardy-Weinberg equilibrium. Plasma TNFα and TNFβ median concentrations were significantly higher in cases when compared to controls (P < 0.01). When plasma TNFα levels were grouped under polymorphic subtypes, patients with mutant TNF- α −308A allele showed significantly higher values (P < 0.001). In addition, plasma TNFα values were significantly elevated in mutant TNF-β +252G allele (P < 0.01). CONCLUSION: This study demonstrated that there is no significant association between SNPs and breast cancer susceptibility in South Indian population. However, plasma TNFα level is significantly elevated with mutant-recessive TNF-α −308 A and TNF-β +252 G alleles of patients.
