the objective of this study was to evaluate the impact of short-term starvation and re-feeding on oxidative stress in mesopotamichthys sharpeyi (günther, 1874). after two weeks adaptation to new conditions, a total number of 270 fingerlings were distributed into nine 300-l fiberglass tanks, equipped with aeration system in three treatments including 4, 8 and 16 days starvation (each in 3 replic...

pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...

Enzymes immobilized on synthetic polyethylene terephthalate (PET) textile surface by resource-efficient inkjet printing technology can promote developments for various novel applications. Synthetic fabrics often require adequate pretreatments to facilitate such process. This work discusses PET–woven fabric pretreatment routes improve wettability alkaline, enzymatic, and plasma processes effecti...

In mice infected with Riley virus (1), the activities of a number of plasma enzymes are permanently elevated (2, 3). Similar, although temporary, increases in plasma enzyme activity have been produced in mice by the administration of certain substances which reduce the phagocytic activity of the reticuloendothelial system (RES), and so it was suggested that in both cases the increased plasma en...

the gradient fractions for L-glutamine y-2-naphthylamide hydrolase activity, i.e. in the absence of glycylglycine, three peaks of activity were again observed. The activities a t densities of 1.24 and 1.15 were only 10% of the transpeptidase activity. However, the peak corresponding to soluble enzyme gave the same activity as that obtained in the presence of acceptor. This indicates that this a...

the aim of the present study was to determine the relationship between histopathological lesions and tissue enzymes in chickens affected by marek's disease.five apparently healthy chickens(as control group)and 25 chickens affected by marek's disease were selected. after consideration of history and gross lesions, tissue samples were collected from kidney, liver, heart, ovary, pectoral...
