The rates of gain, catabolism, synthesis and reutilization of myofibrillar protein were measured in adult rats fed a protein-free diet, low protein diet (2% lactalbumin) or control diet (10% lactalbumin) for 14 to 31 days. Two forms of synthesis were measured: exogenous synthesis (nitrogen derived from diet) and endogenous synthesis (nitrogen derived from catabolized body protein). The rate of ...

the effect of cocl2 as an ethylene synthesis inhibitor on changes of protein pattern was investigated in potato (solanum tuberosum l.) plants cultivar white desiree. in vitro grown plants were subjected to ms medium containing 0, 5, 10, 15, 20, 30, 40 and 60 mg/l cocl2 for 4 weeks. different concentrations of cocl2 showed significant effect on the total soluble proteins. among different concent...

Whole body protein synthesis is reduced during the fed-to-fasted transition and in cases of chronic dietary restriction; however, less is known about tissue-specific alterations. We have assessed the extent to which protein synthesis in cardiac muscle responds to dietary perturbations compared with liver and skeletal muscle by applying a novel (2)H(2)O tracer method to quantify tissue-specific ...

In this work, we investigate optimality principles behind synthesis strategies for protein complexes using a dynamic optimization approach. We show that the cellular capacity of protein synthesis has a strong influence on optimal synthesis strategies reaching from a simultaneous to a sequential synthesis of the subunits of a protein complex. Sequential synthesis is preferred if protein synthesi...

the role of the antioxidant defense system was studied in brassica napus, and subjected todifferent supplementary bands of ultraviolet radiation (uv-a, uv-b and uv-c). this study showed thatuv-b and uv-c induced oxidative stress as evidenced by an increase in lipid peroxidation and totalascorbate content. under uv-b and uv-c treatments, flavonoids and anthocyanins were increasedsignificantly co...

HIGHLIGHTS Bee pollen reduces oxidative damage and thus it can protect S. cerevisiae against to ROS. induces total protein synthesis. cell development MDA levels increases

Aeromonas hydrophila is a gram-negative bacterium which associated with gastrointestinal diseases and septicaemia. This pathogenic bacterium has several virulence factors ranging from pili to the excreted protein which called (Aerolysin) with minor and major effects, respectively. Additionally, Aeromonas hydrophila is a widely distributed bacterium that commonly causes ulcers in cyprinid fish s...
