[The role of nutritional factors in intensive physical activities of sportsmen].

The analysis on the role of major nutrients (proteins, fats and carbohydrates), micronutrients (vitamins and minerals) in a diet of sportsmen is adduced. Requirements for nutrients depend on the volume and intensity of physical exertion during training and competition, not only on the qualifications of sportsmen.

[Characteristic of nutrition for young sportsmen].

Contemporary domestic and international experience of forming a diet for young athletes involved in various kinds of sport was considered at the article.

[Effect of chronic pathology of the upper cervical sympathetic ganglion on the cerebral cortex (experimental study)].

A study was made of the character of disorders of glycogen metabolism and dynamics of the glycogen synthetic properties of sensorimotor cortical neurons at different stages of dystrophic processes under chronic irritation of the anterior cervical ganglion. The authors demonstrate the local glycogen synthesis in synapse ultrastructures, which is of paramount importance for local homeostasis, ensuring high plasticity and dynamism of cortical synapses in information transmission. Decimetric radiotherapy revealed that the sclerosed sympathetic ganglion exerts a permanent tonic effect on the regulation of intracerebral vessels.

[Study of DNA content using a flow cytometry method and steroid hormone receptors in breast cancer].

DNA level measured by flow cytometry and estrogen and progesterone receptors assayed in tissue samples obtained from 85 malignant and 16 benign lesions of the breast. All the benign tumors revealed 2c DNA content and most of them were receptor-negative, while 74.1% of breast carcinomas displayed aneuploidy.
