a hydroponics study was carried out in order to understand the behavior of antioxidant enzymes, soluble protein content and its effect on cell death in different old leaves of durum wheat. two month after planting, the different old leaves were sampled and the activity of super oxide dismutase (sod), catalase, ascorbat peroxidase and guaiacol peroxidase were measured. furthermore, the rate of c...

background chronic kidney disease (ckd) is a prevalent, progressive, and treatable disease. however, lack of enough data about its prevalence in iran is a major obstacle for its early detection. in order to determine the prevalence of the disease in the country, it is necessary to conduct epidemiologic studies especially on populations with ethnic diversity; hence, this study aimed at determini...

A self-perpetuating change in the conformation of the translation termination factor Sup35p is the basis for the prion [PSI+], a protein-based genetic element of Saccharomyces cerevisiae. In a process closely allied to in vivo conversion, the purified soluble, prion-determining region of Sup35p (NM) converts to amyloid fibers by means of nucleated conformational conversion. First, oligomeric sp...

We calculate the baryon asymmetry of the Universe which would arise during a first order electroweak phase transition due to minimal standard model processes. It agrees in sign and magnitude with the observed baryonic excess, for resonable KM parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects. Research supported in part by NSF-PHY...

Currently, there is an urgent need for domestic fermentation activators based on low-cost secondary raw materials. We aimed to study the effect of microbial enzyme preparations with different action hydrolysis proteins and phytin grain bran obtain that could become alternative imported ones.
 studied wheat rye brans; cytolytic, proteolytic, phytase action; multi-enzyme compositions; hydrol...

Dogs are pivotal in Echinococcus granulosus transmission to humans, and dog vaccination provides a very practical and cost-effective prevention strategy. We vaccinated dogs with soluble native proteins isolated from protoscoleces of E. granulosus and induced significant suppression of worm growth and egg production. Accordingly, we tested for vaccine efficacy using recombinant proteins derived ...

1. Mosquito samples from the entire life span including senescence were analysed for weight, protein, RNA and DNA. 2. The results for each component indicate that maximal values are attained during larval development. No changes were observed during metamorphosis or the adult period. 3. The peak concentration of RNA and DNA was reached on the third day larval age. Protein content and weight wer...

As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...

The developmental progress of silverleaf whitefly (Bemisia argentifolii) 3rd instars and 4th instar/pharate adults was monitored using a tracking system that had been designed to identify synchronous individuals in another species of whitefly, the greenhouse whitefly, Trialeurodes vaporariorum. When reared on greenbean under conditions of LD 16:8 and a temperature of 26 +/- 2 degrees C, the bod...
