[Age-related factors in the impact of chemical peeling with retinol on the functional parameters of the skin.].

Retinoids continue to be the main mean for the treatment of photoaging as they are able to align not only the various wrinkles but also to reduce skin pigmentation. Retinol serves as a reserve turned into an active substance by the cell itself in the required amount that triggers the expression of genes responsible for the development of epithelial tissue. The aim of the research therefore was to study the dynamics of the functional parameters of the skin after peeling with retinol in different age groups.

[Regional experience of conducting registry of acute coronary syndrome].

Since 2008 Cardiological Dispensary of Khanty-Mansi Autonomous Okrug "Center of Diagnostics and Cardiovascular Surgery" has been participating in Rossiysky Registry of Acute Coronary Syndrome. In this paper we present some of the results on the use of percutaneous coronary interventions, time intervals, characterizing urgent medical aid to patients with acute coronary syndrome, rate of complications, and mortality.

[ST-segment elevation acute coronary syndrome (according to the data of the District Cardiac Dispensary Register of Surgut)].

Aim: To analyze the individual indicators of emergency medical care in ST-segment elevation (STSE) acute coronary syndrome (ACS) according to the data of the ACS Register of the District Cardiology Dispensary, Center for Diagnosis and Cardiovascular Surgery, Khanty-Mansi Autonomic District-Yugra, Surgut, over time from 2008-2010 and 2011 versus the data of health care facilities taking part in the ACS Register.

Materials And Methods: The quality of medical care for patients with STSE ACS was considered and analyzed in accordance with "The information analytical system user's guide for the integrated rapid assessment of the quality and level of organization of medical care for patients with acute coronary syndrome to "The Federal Register of Patients with ACS".

Results: The data of the ACS Register of the Surgut District Cardiology Dispensary indicate that the majority of patients with STSE ACS are males (86.

[Methodological aspects of evaluation of potential lipid capacity for peroxidation from the serum levels of TBA-active products during iron ion stimulation].

The authors propose a simple and reproducible procedure for using iron ions to stimulate serum lipid peroxidation, with TBA-active products being further determined. The procedure determines the reserve of lipids that can be oxidized during oxidative stress. A combination of direct studies and correlation analysis suggests that low-density lipoproteins and very low-density lipoproteins are the major substrates for lipid peroxidation while high-density lipoproteins show a high resistance to this process.
