The actin cytoskeleton is sensitive to changes in calcium, which affect contractility, actin-severing proteins, actin-crosslinking proteins and calmodulin-regulated enzymes. To dissect the role of calcium control on the activity of individual proteins from effects of calcium on other processes, calcium-insensitive forms of these proteins were prepared and introduced into living cells to replace...

The EPR spectra of the NO complexes of frozen solutions of ascorbic acid-reduced cytochrome oxidase (nitrite reductase) purified from Pseudomonas aeruginosa, of its heme d1-depleted form, and of heme d1 in solutions containing various nitrogenous bases are quite similar to each other as well as to several heme (iron protoporphyrin IX)-containing proteins. The NO complexes of heme d1 (an iron-ch...

In Sterile Insect Technique (SIT) programs, mass-reared males of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), are maintained on a sugar-agar diet before their release into the environment. Several studies suggest that nitrogenous dietary supplements improve the mating competitiveness of the sterile males, thus increasing the cost effectiveness of SIT. Other research, however, ha...

OBJECTIVES The detection of the protein 14-3-3 in the CSF has been shown to be a reliable and sensitive marker for sporadic Creutzfeldt-Jakob disease (CJD). Other brain-specific proteins such as neuron specific enolase (NSE), S-100b, and tau protein have also been reported to be increased in the CSF of patients with sporadic CJD. In 1996 a variant of CJD (vCJD) was described which is likely to ...

Consumption of moderate amounts of animal-derived protein has been shown to differently influence skeletal muscle hypertrophy during resistance training when compared with nitrogenous and isoenergetic amounts of plant-based protein administered in small to moderate doses. Therefore, the purpose of the study was to determine if the post-exercise consumption of rice protein isolate could increase...

JP-45, an integral protein of the junctional face membrane of the skeletal muscle sarcoplasmic reticulum (SR), colocalizes with its Ca2+ -release channel (the ryanodine receptor), and interacts with calsequestrin and the skeletal-muscle dihydropyridine receptor Cav1. We have identified the domains of JP-45 and the Cav1.1 involved in this interaction, and investigated the functional effect of JP...

Abstract A practical solution to the problem of increasing nutritional value bread is use high-protein soy seeds and pumpkin processing product - pectin, potential which improve quality bread, intensify technological process, enhance detoxification properties finished products, including easily fermentable sugars, nitrogenous mineral substances, vitamins, dietary fiber. The possibility using wh...
