THE ROLE OF PSYCHOLOGICAL STRESS IN THE DEVELOPMENT OF ESSENTIAL ARTERIAL HYPERTENSION IN ELDERLY PEOPLE.

This article presents the results of a study of the correlation between psychological stress and essential arterial hypertension in elderly people living in a boarding house. The use of appropriate methods and materials, as well as the t-test to check the equality of the mean values in the two samples, allowed us to establish a certain causal relationship in the development of this disease.

Formate supplementation can increase nickel recovery by Halothiobacillus halophilus.

Acidophilic thiobacilli are traditional biotechnological agents for metal recovery from sulfide ores. Major industrial strains belong to autotrophic bacteria which are used without any organic supplements to stimulate the process. The autotrophic strain Acidithiobacillus ferrooxidans ATCC 21834 is known to use formate as a source of energy under special laboratory conditions.

[Hormonal, radiation and combined therapy of locally advanced prostatic cancer (T3NXM0)].

The analysis is presented of combined treatment of locally advanced prostatic cancer (LAPC), stage T3NXM0, in 158 LAPC patients treated in 1998-2002. The patients were divided into four groups: group 1 (n=72) received hormones in parallel with radiation, group 2 (n=52) received only hormones, group 3 (n=27) received radiotherapy after failure of long-term (1 year and more) hormone therapy, group 4 (n=7) was given teleradiotherapy only. 3-year recurrence-free survival in patients with LAPC showed advantage of the combined treatment (82 +/- 0.

[The proliferative activity of stomach cancer and evaluation of its individual radiosensitivity].

An indirect immunofluorescent method with polyclonal antibodies to thymidine was used to assess the proliferative activity (PA--percent of cells in the S-phase of the cell cycle) of 79 stomach tumors from primary cancer patients. Stomach cancer PA was shown to vary from 0.1 to 69.
