[The role of the floodplain gradient in structuring of testate amoebae communities in the Ilych River].

Forty-two testate amoebae taxa were identified in alluvial soils of floodplain islands in the Ilych River. Among the pedo- and eurybionts, there were aquatic rhizopods. Along the floodplain transect (willow --> meadow --> deciduous forest --> coniferous forest), the testate amoebae community changed directly. There are spatially homogeneous (low beta-diversity) testacean communities but species rich on the local level (high alpha-diversity) within forests. Within willows and meadows, communities are characterized by low alpha-diversity and high heterogeneity that leads to high gamma-diversity.

[Incidence of ischemic heart disease: its relation with main risk factors and effectiveness of long-term multifactorial prevention at an industrial enterprise]. / Rasprostranennost' ishemicheskoi bolezni serdtsa. Ee sviaz' s osnovnymi faktorami riska i éffektivnost' mnogoletnei mnogofaktornoi profilaktiki na promyshlennykh predpriiatiiakh.

AIM: To study the prevalence of ischemic heart disease (IHD) and its various clinical forms depending on both sexes, age, profession, risk factors and efficiency of active prevention programs. MATERIAL AND METHODS: 1848 males and 1643 females were inspected as a control group. 8326 males and 13,116 females volunteers were included into the groups of active prevention and observation. RESULTS: Risk factor correction produced a significant decrease in both systolic and diastolic BP mean levels, prevalence of ECG abnormalities together with smoking habits occurrence, overweight and their combination. The general mortality rate, IHD and stroke mortality were significantly less in the group of prevention as well as the number of days of temporary disability. CONCLUSION: Primary and secondary "in office" prevention for 5 to 10 years diminished the prevalence of risk factors and events of IHD. The presence of IHD, risk factors increased general mortality rates and cardiovascular mortality rates in both groups. The multifactorial prevention of IHD contributed to a decline in general mortality rates and cardiovascular mortality rate.

[An analysis of the indices of ambulatory circadian blood pressure monitoring in patients with arterial hypertension]. / Analiz pokazatelei ambulatornogo sutochnogo monitorirovaniia arterial'nogo davleniia u bol'nykh arterial'noi gipertoniei.

The authors have found that more accurate prognosis of left ventricular myocardial hypertrophy (LVMH) may be made basing on fluctuations and variability of arterial pressure throughout the day: significant fluctuations of arterial pressure at night and pronounced variability of systolic arterial pressure in the day time and at night are indicative of essential hypertension instability and may contribute to LVMH progression. Of still greater prognostic significance is assessment of 24-h arterial pressure rhythm by the degree of a night fall (DNF) in diastolic arterial pressure (DAP). A disturbed 24-h rhythm of arterial pressure (a fall in DNF of DAP) is a predictor of LVMH development.
