The ecology in terms of physico-chemical and biological properties of Urpod beel and Kumri beel of Goalpara district of Assam were assessed from2001 to 2003. Physico-chemical properties of both the wetlands were observed favourable. Biological properties such as plankton population and primary productivity fluctuated within the permissible limits. However, eutrophication tendency appeared in both the wetlands due to autochthonous and allochthonous input. Source

Objectives: Chronic consumption of high-carbohydrate, high-fat (HCHF) diet induces metabolic syndrome (MetS) and markedly impairs the ultra-structure of organs. To our knowledge, no scientific study has yet to report the effect of withdrawal of an HCHF diet on MetS-associated ultra-structural abnormalities in affected organs and tissues. Therefore, the aim of this study was to investigate the effects of subchronic withdrawal of the HCHF diet, specifically with a pathophysiological approach. Methods: Wister albino rats (N = 72) were divided into three groups: Groups A and B were fed a standard basal diet and an HCHF diet, respectively, for 16 wk. Group C was on an HCHF diet for the initial 12 wk and then returned to basal diet for 4 wk. Histopathological changes in the heart, lungs, liver, spleen, pancreas, small intestine, kidney, white adipose tissue (WAT), skeletal muscle, and hippocampus of the brain were monitored at 4, 8, 12, and 16 wk. Results: Lipid droplets (LDs) in liver, fibrosis in the pancreas, abnormalities in the glomerulus of the kidney, and an increase in the size of adipocytes were observed in groups B and C at week 12. Withdrawal of the HCHF diet in group C showed the onset of regenerative features at the ultra-structural level. HCHF diet-fed rats in group B had higher body weights; raised lipid profiles, blood glucose levels, and insulin resistance than basal diet-fed rats in group A and HCHF to basal diet-fed rats in group C at week 16. Conclusion: An HCHF diet induces ultra-structural abnormalities, which are significantly reversed by subchronic withdrawal of a MetS-inducing HCHF diet, indicating the onset of natural recovery at the ultra-structural level of affected organs. © 2016 Elsevier Inc.

In order to obtain analytic solutions of the spin dependent coupled Altarelli-Parisi equations at leading order (LO) in the small x limit we have applied here the method of successive iterations. We have shown that barring the small x limit of the splitting functions at LO, this method does not require any other adhoc assumptions to obtain analytic solutions of the coupled AP equations. We have observed that, after successive iterations our solutions come closer to the exact numerical results. © 2012 IACS. Source

Folklore studies have revealed that Musa balbisiana Colla (MB; Family: Musaceae) has high medicinal properties. The purpose of the present study is to evaluate antihyperglycemic, and antioxidant activity of MB extracts in streptozotocin (STZ) induced diabetic rats. In vitro antioxidant and antidiabetic activity of MB extracts, i.e., root extract (RE), shoot extract and inflorescence extract were determined by using various methods viz 1,-1-diphenyl-2-picrylhydrazyl (DPPH) and a method to assess their possible effect on glucose diffusion across gastrointestinal tract and identify bioactive compound of potent extract. In vivo antilipidemic and antidiabetic activity was evaluated by administrating oral dose of RE for 15 days on STZ- induced diabetic rat. RE showed highest antioxidant activity by scavenging DPPH radical (IC50 32.96 μg/ml) and inhibit 30% glucose movement in vitro. The methanol extract of root showed the presence of calyx [4] arene category of the compound. Furthermore, RE treated rat revealed a reduction in fasting blood glucose (62.5%), serum total cholesterol (36.2%), triglyceride (54.5%), and low-density lipoprotein (50.94%) after 15 days as compared to STZ treated animal. There was an initiation of regenerative structures of the affected organs after 15 days of RE treatment. Histopathological observations clearly differentiate the structural changes in pancreas, liver, and kidney of STZ and RE treated group. The presence of calyx [4] arene class of compound may be responsible for its antioxidant and antidiabetic properties by absorbing glucose in vivo. © 2016 Kalita, Boruah, Deori, Hazarika, Sarma, Kumari, Kandimalla, Kotoky and Devi.

The study was conducted in a society pond of Gandhibasti village of Abhayapuri, Bongaigaon, Assam to assess the impact of duck droppings on water quality and pond productivity. The pond was integrated with ducks (Anas platyrhynchos) to obtain the benefit of duck litters on the pond productivity and fish growth. The mean dry weight of 80 ducks excreta was estimated as 3.864 kg/ha/day, discharging into the pond. 18,000 fingerlings. Indian major carps along with few exotic carp were stocked in the month of April, 2013. Supplementary feed was also given to the fishes in alternate days to ensure their steady growth. All the studied physico-chemical parameters were found within the permissible limit and the growth of fishes was also satisfactory. The maximum growth was recorded in Catla followed by silver carp, common carp, Rohu and Mrigala. © 2015, Technoscience Publications. All rights reserved. Source
