Progesterone-containing contraceptives do not have a significant impact on metabolic processes and can be prescribed to patients with systemic (diabetes mellitus, obesity) and other diseases. Desogestrel is a part of oral preparations in a dose of 75 mcg. The main mechanism of its contraceptive action is Suppression of ovulation (in 97% of cases). The frequency of pregnancy is 0.17 for 100 women-years. Progesterone-containing contraceptives should not be considered, as preparations of the second choice when deciding on the issue of family planning. According to the recommendations of the Center for Disease Control and Prevention organization of health, desogestrel is an acceptable contraceptive option for women with somatic diseases, defined tumor pathology and thrombotic states in the anamnesis.

The results of studies on the role of growth biostimulants in the exogenous regulation of potato productivity on sod-podzolic soils of the Moscow region are presented.Studies have established the specificity of the action of phytohormones.The stimulating effect of the drugs manifested itself in the intensification of metabolic processes, changing the direction of biochemical reactions, which led to an increase in productivity.

For single-sludge denitrification systems, modelling of anoxic reactors currently uses the kinetics of aerobic heterotrophic growth together with a correction factor for anoxic conditions. This coefficient is computed on the basis of respirometric measurements with the assumption that the heterotrophic yield remains the same under aerobic and anoxic coditions. The paper provides the conceptual proof that the yield coefficient is significantly lower for the anoxic growth on the basis of the energetics of the related metabolic processes. This is used for the interpretation of the very high values for the correction factor experimentally determined for a number of industrial wastewaters. A default value for the anoxic heterotrophic yield coefficient is calculated for domestic sewage and compatible wastewaters and proposed for similar evaluations.
