The effect of triathlon (3.8 km swimming, 180 km biking, 42 km running) and of its short variant (1.5 km swimming, 42 km biking, 14 km running) was studied in 7 and 14 well-trained men, respectively. The level of plasma glucose, total cholesterol, HDL, LDL did not change significantly during the competition. FFA concentration increased significantly (by 439 and 61%, respectively). Triglycerides concentration decreased during the prolonged variant. Both variants of triathlon caused a pronounced rise in the cortisol level and moderate increase in somatotropin and progesterone levels. Testosterone concentration increased during a short variant and decreased during a prolonged one. Insulin and C-peptide levels decreased. All those changes in hormones concentration are consistent with an increased lipolytic activity and, may be, with increased glycolytic activity (maintenance of the normal glucose concentration in blood). The rise in the aldosterone level reflects the homeostatic activity in maintaining electrolyte balance. 相似文献

Mitochondrial genomes of many eukaryotic organisms do not code for the full tRNA set necessary for organellar translation. Missing tRNA species are imported from the cytosol. In particular, one out of two cytosolic lysine tRNAs of the yeast Saccharomyces cerevisiae is partially internalized by mitochondria. The key protein factor of this process is the precursor of mitochondrial lysyl-tRNA synthetase, preMsk1p. In this work, we show that recombinant preMsk1p purified from E. coli in native conditions, when used in an in vitro tRNA import system, demonstrates some properties different from those shown by the renatured protein purified from E. coli in the denatured state. We also discuss the possible mechanistic reasons for this phenomenon. 相似文献

Impact of inoculation of wheat seeds with endophytic strains of B. subtilis bacterium on revealing cadmium phytotoxicity of the plants was investigated. It was shown that, in the presence of Cd in the plants whose seeds were inoculated with the above bacteria, the activities of catalase and peroxidase and the content of nonprotein thiols were increased, while an intensity of lipid peroxidation decreased. Moreover, inoculation of plant seeds with the bacteria contributed to lowering the metal content in plant shoots. 相似文献
