[Pathology diagnostics by human breath analyze].

Modern medicine experiences deficit of inexpensive rapid screening technologies despite progress in the development of diagnostic methods for various diseases. A promising approach is the analysis of exhaled air known to contain thousands of volatile organic substances whose composition differs considerably in health and disease. We isolated certain compounds that may be used as biomarkers of cardiovascular pathology (nitric oxide, carbon monoxide, pentane, isoprene, acetone).

[The effect of insulin on circadian rhythm of voluntary locomotor activity in rats].

Effects of single intranasal administration of 0.2 ng insulin at different moments of the projected daily cycle (ZT = 1, ZT = 7, ZT = 13 and ZT = 19) on the circadian rhythms of voluntary locomotor activity (wheel-running) were studied in Wistar male rats. Insulin administered at ZT-7 or ZT-13 induced a statistically significant phase advance by 4.

[Comparative characteristics of the physiometric parameters of schoolchildren' physical development].

The physiometric parameters (exercise performance, muscle strength, and lung capacity) were monitored in schoolchildren over the 15-year period. There has been a reduction in exercise performance, muscle strength and an increase in lung capacity in the past 15 years, which the pediatricians should take into account to detect physical development abnormalities in schoolchildren.

[Impact of ambient air pollution on the prevalence of main symptoms of asthma in children].

The impact of ambient air pollution on the prevalence of main symptoms of asthma was analyzed in children. A total of 3,506 children were interviewed using the ISAAC questionnaire. The prevalence of the abnormality was studied via continuous questioning in children aged 7-8 and 13-14 years, who lived in areas with varying aerogenic loads.

[The predictors of development of bronchial asthma in children].

The study of the predictors impacting the development of bronchial asthma in children was implemented. For each risk factor the chances ratio and its 95% confidence interval were calculated. The sample consisted of 280 children with bronchial asthma aged from 7 to 14 years and 210 healthy children of the same age.
