the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...

The thiol reagent dithiothreitol inhibits the activity of a core GDP-fucose-N-acetylglucosaminide alpha-6-fucosyltransferase in plasma and blood-cell homogenates, while promoting the activity of alpha-2- and alpha-3-fucosyltransferases. The latter enzymes catalyse transfer of fucose on to terminal galactose and subterminal N-acetylglucosamine residues respectively. A thiol-blocking reagent N-et...

The effects of the exudate of Aloe barbadensis leaves on oxidative stress and some antioxidant status of streptozotocin induced diabetic rats were studied. There was significant reduction in scavenging enzymes like superoxide dismutase (SOD) activity and significant increase in signs of oxidative tissue damage, such as lipid peroxidation products (plasma MDA) in streptozotocin induced diabetic ...

P LATELETS STORED in artificial media have a shortened Cr51 survival time,1 decreased adenosine triphosphate concentration ( ATP ) and decreased activity of glycolytic enzymes.2 These changes are not observed when platelets are stored in plasma for a comparable period of time. Since storage of platelets in artificial media is associated with decreased activity of some platelet enzymes, incubati...

the present study investigates the effects of water temperature on digestive enzymes activity and food transit time in caspian kutum ( rutilus kutum ) larvae. caspian kutum larvae (532 ± 0.05 and 543 ± 0.02 mg) were divided into two groups with three replicates and reared at different water temperature i.e. 25.6 ± 0.4°c (t 1 ) and 18.4 ± 0.1°c (t 2 ). at the end of the experiment, sampling of i...

abstract earthworms are an important component of soil fauna, and play a crucial role in the improvement of soil properties. however, very little is known of the interactive influence of earthworms and organic materials on soil enzyme activities, particularly in arid and semi-arid soils. the low organic matter content and the significant role of earthworms in stimulating microbiological and bio...

protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. for this purpose, a 4 months laboratory experiment was carried out using two types of urban soils (sofia, bulgaria): native park soil and anthropogenic soil. the effect of the obtain...

The aim of this study was to evaluate the effect trans-anethole in combination with methotrexate, compared monotherapy or on inflammatory parameters and oxidative stress arthritic rats. experimental model arthritis induced by Freund's complete adjuvant (AIA) rats used. Treatment monotherapy, started day AIA induction continued for 21 days. association anethole (62.5 mg/Kg) methotrexate (6 thera...

Kuoppala, Antti, Ken A. Lindstedt, Juhani Saarinen, Petri T. Kovanen, and Jorma O. Kokkonen. Inactivation of bradykinin by angiotensin-converting enzyme and by carboxypeptidase N in human plasma. Am J Physiol Heart Circ Physiol 278: H1069–H1074, 2000.—Because bradykinin (BK) appears to have cardioprotective effects ranging from improved hemodynamics to antiproliferative effects, inhibition of B...
