β-glucosidases catalyze the selective cleavage of glucosidic linkages and are an important class of enzymes having significant prospects in industrial biotechnology. These are classified in family 1 and family 3 of glycosyl hydrolase family. β-glucosidases, particularly from the fungus Trichoderma, are widely recognized and used for the saccharification of(More)
Three cases of hepatic vein and retrohepatic inferior vena caval injuries are reported, and the literature is reviewed. Our experience, coupled with a critical review of the literature reveals that successful vascular isolation of the relatively inaccessible retrohepatic vena cava and/or hepatic veins is the key to optimal surgical management of major(More)
The modification of polymers has received much attention recently. Among the methods of modification of polymers, grafting is one of the promising methods. In principle, graft co-polymerization is an attractive method to impart a variety of functional groups to a polymer. Graft co-polymerization initiated by chemical treatment, photo-irradiation,(More)
Tilapia mossambica, Peters were exposed to a sub-lethal concentration of 0.5 mg · 1−1 of mercury as mercuric nitrate [Hg(NO3)2] in aquaria under controlled laboratory conditions. Main clinical symptoms such as inappetence and ataxia appeared after 2 days of exposure. Blindness was noticed in 60% of the fish after a 10 day exposure. The whole-animal oxygen(More)
Acetylcholinesterase (AChE) activity of T. mossambica in relation to the interacting effects of aging and sub-lethal concentrations of Dichlorvos was studied. The enzyme activity of brain and liver decreased with increasing size (and age) and DDVP-exposed fish showed considerable inhibition of brain and liver AChE. The degree of enzyme inhibition followed a(More)
