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.

On detection of multiple object instances using Hough transforms.

Hough transform-based methods for detecting multiple objects use nonmaxima suppression or mode seeking to locate and distinguish peaks in Hough images. Such postprocessing requires the tuning of many parameters and is often fragile, especially when objects are located spatially close to each other. In this paper, we develop a new probabilistic framework for object detection which is related to the Hough transform.

[Modern methods of antibiotic determination in biological samples and drugs (review)].

The analysis of the literature data for the last 10 years showed that microbiological, spectroscopic, chromatographic and electrochemical methods were most often used in quantitative determination of antibiotics in biological samples and drugs. Beta-lactams, aminoglycosides, tetracyclines, fluoroquinolones and other antibiotics were widely investigated. The characteristics of different methods of the antibiotic determination were discussed.

[Study of the activity of receptors with nonmyelinated fibers during heat exposure of the hairy cat skin].

A nerve activity in heating of the cat hairy skin was studied in acute experiments in order to find out if the C-receptors take part in peripheral coding of heat information. An integrative cross-correlation technique was used to analyse neurograms in the real time. No C-afferent activity was found in the thermal stimulation up to 41 degrees C of the hairy skin.
