It is shown that natural chiral catalysts, which could be formed e.g., from optically active amino acids on basic natural
minerals, could lead, at early stages of evolution, to the formation of rather complex optically active products from starting
achiral compounds. Using biomimetic combinations of vanadium ion complexes and chiral ligands synthesized from widely occurring
natural compounds, we created novel catalytic systems, permitting the transfer of optical activity in the course of catalytic
chemical transformations of achiral compounds. We found that in the presence of natural clay, optically active terpenoids
from the pinane series undergo multistage transformations, forming unexpected new products with preservation of optical purity. 相似文献

The activity of serum complement proteins and the level of steady brain potential in patients with systemic lupus erythematosus and rheumatoid arthritis were determined. The statistical analysis indicated that there is a correlation between the parameters of the complement system and neurophysiological characteristics. The differences between rheumatoid arthritis and systemic lupus erythematosus are observed in the mean values of activity of complement proteins and the steady potential, their dispersions, and the structure of correlations between immunological and neurophysiological parameters. 相似文献

We studied the content of Al, Cd, Co, Cu, Fe, Mg, Mn, P, Pb, S, and Zn in the liver, kidneys, lungs, and spleen of mice with total radiation dose of 7.5 Gy using atomic emission spectral analysis with an inductively coupled argon plasma. The qualitative content of macro- and microelements and coordination between their concentrations statistically determined from coefficients of linear correlation differ between the tissues of the irradiated and control animals. Radiation damage decreases phosphorus content in all studied organisms and is a marker of disturbed conjugated oxidative phosphorylation. The most significant radiation-induced disturbance of macro- and microelement balance was detected in the spleen; it features decreased content of phosphorus, magnesium, and cobalt, as well as increased content of zinc and aluminum and considerably increased iron content. The revealed macro- and microelements disbalance in spleen, liver, kidneys, and lungs can be considered as a test for primary biological response to radiation damage. 相似文献

Analysis of psychological, social, and psychophysiological mechanisms underlying the formation of adaptive responses during puberty demonstrated a significant dependence of adolescent behavioral, autonomic, and endocrine parameters on sociobiological factors that determine the identification and individualization of genetically determined behavioral programs. Comparison of the adaptive capabilities of students from an innovative educational institution and from a vocational school showed that the levels of completeness of their adaptation were different and depended on social support, typological features, and autonomic regulation. 相似文献
