Adolescent is the period of rapid physical and psychological changes and considered to be the most vulnerable segment of the population in relation to nutritional, physical and behavioral aspects. The changing life style pattern, dietary habits, peer pressure to achieve educational success and limited finances create a stress on them.
The reciprocal interaction between stress and reproductive axis is manifested by ovulatory abnormalities and infertility in female adolescent girls. The main objective of this study is to find out whether the adolescent girls are facing any kind of stress-related hazards in reference to their diet, academic pressure and modern life-style pattern which can impair their health status.
50 adolescent girls (12-19 years) were surveyed using pre-tested questionnaires about nutritional status, general heath, menstrual cycle and source of stress. Height, weight, BMI, BMR and body fat content (by Bioimpedance analyser), blood pressure, heart rate and O2 saturation was measured.
The adolescent girls were stunned which indicates chronic malnutrition and lack of physical growth. Majority of them had a lower BMI (younger) and higher dysmenorrhea (older). Academic workload was found to be the most stressful event followed by, exercising, inadequate sleep, unhealthy dietary habits, and socio-economical status.

Paraquat, a herbicide widely used in agriculture for better crop production, is an environmental toxin and causes oxidative stress-induced systemic damages in plants, animals and humans. Epidemiological studies report that paraquat toxicity is related to the onset of parkinsonism in humans. Animal experimentations indicate that paraquat toxicity causes the cellular and molecular changes associated with parkinsonism. Experimental evidences show that bloodbrain-barrier limits the paraquat entry in brain of primates and humans and therefore, the doubts remain for a direct paraquat-induced parkinsonism in human. To define a remedial measure, extensive studies are required on the cause and prognosis of Parkinson’s Disease induced by such environmental toxicant.

Argonaute proteins have established themselves as key players in the RNAi mechanisms across all domains of life. In plants several types of argonaute proteins are present which are involved in the different small RNA related pathways. Likewise in animals, fungi (Quelling) and Protists argonaute proteins are mostly involved in the microRNA and siRNA related pathways. In some higher eukaryotic taxa they serve as elongation factors as well. This study explores the sequence complexities of Argonaute 1 protein across various domains of life and attempts to identify whether any intrinsically unstructured regions are present in the proteins under study.

Background and Aim: Recent studies try to find out parameters which can be used as predictors of type2 diabetes. Few investigations done in children of Type2 diabetic parents suggest the impact of family history and the presence of certain risk factors of the disease at an early age. We studied the presence of insulin resistance and changes in urinary pH in offspring of diabetic parents. Materials and Methods: Thirty subjects with one or both diabetic parents were compared with thirty subjects who are offspring of non diabetic parents. Results: No stastically significant difference was observed between the two groups in any of the values. Conclusion: Using insulin resistance and urinary pH as predictors of type2 diabetes is questionable. We may have to do further studies associating other risk factors like increased BMI with the family history.
