heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
BACKGROUND/AIM The excessive apoptosis of intestinal epithelial cells (IECs) partly accounts for the development of colonic inflammation and eventually results in ulcerative colitis (UC). Humanin, an endogenous anti-apoptotic peptide, has previously been shown to protect against Alzheimer's disease and a variety of cellular insults. The present study aimed to investigate the effects of glysin v...
Among the conducting polymers, Polyaniline and its derivatives have been studied extensively in the last decade with improvements in processing having the key role in establishing the intrinsic electrical properties. In the present paper, the camphor sulphonic acid [CSA] doped Poly (o-toluidine) [POT] was prepared using chemical oxidative polymerization method. The prepared CSA doped POT was ch...
Introduction and Aim: An efficient aspect of two step synthesis tetrahydro pyrimidine carboxamide derivatives were developed by Biginelli reaction. The two-step synthesized 1,2,3,4-tetrahydropyrimidinecarboxamide compounds evaluated In-vitro studies like antifungal bacterial activities. Few shown excellent zone inhibition against fungal Microbial In this study showed significant effect action d...
In order to fully understand the variations of fruit quality-related phytochemical composition in Chinese bayberry (Myrica rubra Sieb. et Zucc.), mature fruit of 17 cultivars from Zhejiang and Jiangsu provinces was used for the investigation of fruit quality attributes, including fruit color, soluble sugars, organic acids, total phenolics, flavonoids, antioxidant capacity, etc. Sucrose was the ...
