Indices of physical work capacity in athletes with different types of adaptation of the cardiorespiratory system that are engaged in various kinds of sports and have sports ranks from Master of Sports to Grade 2 have been studied. It has been shown that the highest physical work capacity is typical of athletes that have the inotropic type of adaptation, and the lowest, of athletes with the chronotropic type of adaptation. High indices of physical work capacity were recorded in athletes with the respiratory type of adaptation. Types of adaptation affect the indices of physical work capacity, and it is possible to forecast sports results on their basis. 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

Wheat (Triticum aestivum L., cv. Kazakhstanskaya 10) seedling growth activation by the endophytic 11BM strain of the bacterium Bacillus subtilis Cohn and the involvement of phytohormones in this process were studied. At the concentration used, bacteria enhanced wheat
root and shoot growth as compared to control. Biotests demonstrated auxin-, cytokinin-, and gibberellin-like activities of
the endophyte, but the result depended on the way of experiment performing. When wheat seeds were treated with the spores
of B. subtilis 11BM strain, the concentrations of IAA and ABA increased transiently in the roots and shoots of the seedlings. The involvement
of IAA oxidase in the plant response to inoculation with bacteria was shown; it was accompanied by a decrease in enzyme activity,
which occurred later than auxin accumulation. It was concluded that observed changes in the hormonal status of wheat plants
under the influence of the endophytic bacterial strain may be one of the mechanisms for seedling growth stimulation. 相似文献

We studied the effect of cadmium and nickel on Sinapis alba L. plants inoculated with endophytic strains of Bacillus subtilis. It was shown that treatment of S. alba seeds with endophytic strains of bacteria B. subtilis improves plant resistance to the toxic effect of cadmium and nickel and reduces manifestation of oxidative stress in the presence of higher levels of metal ions in the above-ground part of plants. Anti-stress effect and the ability of endophytic strains of B. subtilis to intensify uptake of cadmium and nickel ions by S. alba plants may be used for phytoextraction of heavy metals and stimulation of plant growth in contaminated areas. 相似文献

The activity of various plant peroxidases and the ability of their individual isoforms to bind chitin was studied. Some increase in peroxidase activity was observed in crude extracts in the presence of chitin. Activated peroxidases of some species fell in the fraction not sorbed on chitin and those of other species can bind chitin. Only anionic isoperoxidases from oat (Avena sativa), rice (Oryza sativa), horseradish (Armoracia rusticana), garden radish (Raphanus sativus var. radicula), peanut (Arachis hypogaea), and tobacco (Nicotiana tabacum Link et Otto) were sorbed on chitin. Both anionic and cationic isoforms from pea (Pisum sativum), galega (Galega orientalis), cucumber (Cucumis sativus), and zucchini (Cucurbita pepo L.) were sorbed on chitin. Peroxidase activation under the influence of chitin was correlated to the processes that occur during hypersensitive reaction and lignification of sites, in which pathogenic fungus penetrates into a plant. The role of chitin-specific isoperoxidases in inhibition of fungal growth and connection of this phenomenon with structural characteristics of isoperoxidases are also discussed. 相似文献

The effect of chitooligosaccharides on hydrogen peroxide production and anionic peroxidase activity in wheat coleoptiles 总被引:2,自引:0,他引:2

We studied the effects of chitooligosaccharides (ChOS) with a mol wt of 5 kD, the degree of acetylation of 65%, and the concentrations from 0.01 to 100 mg/l on the content of hydrogen peroxide in incubation medium and the activity of anionic peroxidase (pI 3.5) in the segments of wheat (Triticum aestivum) coleoptiles. H2O2 production and peroxidase activity were found to be dependent on the ChOS concentration. After 3 h of incubation, the highest H2O2 level in medium was observed at 0.01 mg/l ChOS, whereas after 6h, at 1 mg/l. After 3 h of incubation, ChOS suppressed peroxidase activity. After 6 h of incubation, high ChOS concentrations enhanced peroxidase activity. IAA favored H2O2 accumulation in medium and suppressed anionic peroxidase. The involvement of ChOS in the control of the level of reactive oxygen species and anionic peroxidase activity in plant cells is suggested.Translated from Fiziologiya Rastenii, Vol. 52, No. 2, 2005, pp. 238–242.Original Russian Text Copyright © 2005 by Yusupova, Akhmetova, Khairullin, Maksimov.This revised version was published online in April 2005 with a corrected cover date. 相似文献

Inhibition of the novel oligopeptidase B from Serratia proteamaculans (PSP) by basic pancreatic trypsin inhibitor, Zn2+ ions, and o- and m-phenanthroline was investigated. A pronounced effect of calcium ions on the interaction of PSP with inhibitors was demonstrated.
Inversion voltamperometry and atomic absorption spectrometry revealed no zinc ions in the PSP molecule. Hydrophobic nature
of the enzyme inhibition by o- and m-phenanthroline was established. 相似文献

This paper presents the results of a pre-clinical study of the immunogenicity and efficacy of an egg-derived, inactivated, whole-virion adjuvanted vaccine (Refluvac®) on ferret models. For this purpose, groups of eight ferrets (6 to 7 months old) were injected with 0.5 mL of vaccine specimens containing 3.75, 7.5 or 15.0 μg of virus hemagglutinin. Administration was intramuscular and given either as a single dose or as two doses 14 days apart. All vaccine specimens manifested immunogenicity in ferrets for single (HI titer, from 51 ± 7 to 160 ± 23) and double (HI titer, from 697 ± 120 to 829 ± 117) administrations. To assess the protective effects of the vaccine, ferrets from the vaccinated and control groups were infected intranasally with pandemic virus A/California/7/09 (H1N1) pdm09 at a dose of 106 EID50/0.5 mL. Fourteen days post-infection, the ferrets inoculated with single or double vaccines containing 3.75, 7.5 or 15.0 μg of hemagglutinin per dose showed no signs of influenza infection, weight loss, or body temperature rise, and no premature deaths occurred. The number of vaccinated ferrets shedding the virus via the upper airway, as well as the amount of virus shed after infection, was significantly reduced in comparison with animals from the control group. Based on our results, we suggest that a single vaccination at a dose of 3.75 or 7.5 μg hemagglutinin be used for Phase I clinical trials. 相似文献
