Ethylene/propylene (E/P) and ethylene/propylene/5-ethylidene-2-norbornene (E/P/ENB) copolymers were obtained on -Et(2-MeInd)ZrMe activated by a number of isobutylaluminium aryloxides: (2,6-BuPhO-)AlBu (1-DTBP) (2,6-Bu,4-Me-PhO-)AlBu (1-BHT), (2,4,6-BuPhO-)AlBu (1-TTBP), (2,6-Bu,4-Me-PhO-)AlBu (2-BHT), (2,6-BuPhO-)2AlBu (2-DTBP), [(2-Me,6-Bu-CHO)AlBu] (1-MTBP), [(2,6-Ph-PhO)AlBu] (1-DPP). This study shows how the structure of an activator influences catalytic activity and polymer properties, such as the copolymer composition, molecular weight characteristics, and thermophysical and mechanical properties. It has been shown that both the introduction of a bulky substituent in the para-position of the aryloxy group and the additional aryloxy group in the structure of an activator lead to a significant decrease in activity of the catalytic system in all studied copolymerization processes.

Methods: Seventeen hospital and outpatient medical centres from 13 regions of the Pilot Project. Baseline questionnaires assessed the involvement of multidisciplinary teams, staffing, and the equipment in healthcare facilities.
Background: Rehabilitation measures are crucial for maintaining clinical benefits of coronary artery bypass grafting (CABG) surgery. We evaluated the clinical efficacy of a medical centre- and home-based cardiac rehabilitation (CR) for patients after CABG in an out-patient setting.
Methods: The study included 36 male patients 3-8 weeks after CABG that were randomly assigned to either study or control group.
This review summarizes the main provisions of the new, issued in 2016, recommendations of the European Society of Cardiology and Atherosclerosis Society in cooperation with the European Association on Cardiovascular Prevention and Rehabilitation on Cardiovascular disease prevention and Management of dyslipidemia. In these recommendations, the following trends can be traced distinctly: priority in primary prevention is given to non-drug methods of influence; targets of hypolipidemic therapy are identified not only for low density lipoprotein (LDL) cholesterol (CH), but also for non-high density lipoprotein (HDL) CH, especially in cases of concomitant hypertriglyceridemia. In the field of therapy, in which statins remain the main tool of correction of hyperlipidemia, it is recommended to more widely resort to the use of combination therapy, especially in cases of familial hypercholesterolemia or intolerance to statins; introduction of a new class of drugs- inhibitors of proprotein convertase subtilisin/kexin type 9 makes it possible to further reduce the level of LDLCH, lipoprotein(a) more than 60%.

Background: Decisions about fat consumption and levels of physical activity are among the everyday choices we make in life and risk of coronary heart disease (CHD) can be affected by those choices.
Objective: The purpose of this study was to investigate the influence of a standard fat load combined with physical exertion of different intensities on the plasma lipid profile of CHD patients and CHD-free individuals.
Methods: This study looked at the influence of different intensities of physical exercise on postprandial lipid metabolism in 20 healthy men and 36 men with diagnosis of CHD.
All available data on rehabilitation and secondary prevention after ST elevation acute myocardial infarction (STEAMI) are summarized in corresponding first national recommendations. These recommendations are based on legislative acts concerning medical rehabilitation which have been adopted in Russian Federation during recent years. Recommendations have also taken into account experience of Russian investigators and special national features of development of cardiorehabilitation system as well as possibilities of creation of its material-technical base in this country.

In this study we compared the physiological parameters and tolerance to osmotic and non-osmotic stresses of three osmotolerant yeast species, Debaryomyces hansenii, Pichia farinosa (sorbitophila) and Zygosaccharomyces rouxii, with those of wild-type Saccharomyces cerevisiae. Although the osmotolerant species did not differ significantly in their basic parameters, such as cell size or growth capacity, they had different abilities to survive anhydrobiosis, potassium limitation or the presence of toxic cationic drugs.

Subjects And Method: The trial included 100 patients after ECL who were randomized into 2 groups: those who had gone through Patient School (PS) and received a 6-week course of controlled ET (a study group (Group S)) and those who had gone through PS only (a control group (Group C). The patients of both groups were recommended a home ET program and, according to its implementation, they formed 2 subgroups: Subgroup A (home ET+) comprising 51 patients who had trained themselves at home) and Subgroup B (home ET-) consisting of 46 patients who had not.

Patients (n=100) were randomized into 2 groups - intervention (main group "M", n=50) and control (group "C", n=50) during weeks 2-8 after EVI. Efficacy of undertaken measures was assessed by results of laboratory (lipids), instrumental (electrocardiogram - ECG, exercise test on veloergometer - VEM-test, echocardiography - EchoCG) and clinical investigations.

Material And Methods: A total of 500 outpatients with primary AH and risk factors including the risk of stroke received Hyzaar (losartan 50/100 mg and hydrochlorthiaside 12.5/25 mg) for one year.
Aim: To investigate efficacy of early and long term physical training (PT) of moderate intensity in conditions of practical health care in Russia in patients with ischemic heart disease (IHD) of able to work age - survivors of acute coronary events.
Material And Methods: Three hundred ninety two patients were enrolled in this study. They were randomized into intervention group " O" (n=197) and control group " C" (n=195).
Aim: To assess efficacy of early and long-term exercise in patients with ischemic heart disease (IHD) after acute coronary events (acute myocardial infarction--AMI, unstable angina--UA, coronary artery bypass grafting--CABG) in wide outpatient medical practice of Russia.

Intensity of exercise was limited by severity of stable effort angina and was > 95, 80 and 70% of predicted maximum in patients with class I (n=10), II (n=12) and III (n=14) angina, respectively. High intensity exercise provoked development of atherogenic dyslipidemia: elevation of levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, apolipoprotein B and apolipoprotein B/A1 ratio, and lowering of levels of high density lipoprotein cholesterol and apolipoprotein A1.

Favorable pleiotropic effects of atorvastatin such as normalization of endothelial function, antiinflammatory, antithrombotic and antioxidant activity contribute to stabilization of atheromatous plaques. Clinical trials revealing early and significant effects of the drug on main end points have demonstrated its high value for primary and secondary prevention of atherosclerosis.

Effects of high (100 and 80 kg) and moderate (60 kg) intensity static leg exercise on blood serum lipoproteins and apolipoproteins (apo) A1 and B were studied in healthy subjects (n=11) and patients with coronary heart disease and class I angina (n=11). Static leg exercise with loads exceeding 60 kg were associated with atherogenic changes of blood lipid transport system: elevation of levels of triglycerides, apoprotein B and apo B/A ratio both in healthy subjects and patients, and of total and low density lipoprotein cholesterol in patients. These post exercise changes were more pronounced in the presence of fasting hyperlipidemia and their severity increased with increase in duration of exercise.

Both in healthy persons and patients high intensity (100 and 80%) exercise was associated with atherogenic changes of lipid transport system: increases of levels of total and low density lipoprotein cholesterol, triglycerides, apolipoprotein B and apo B/apo-A1 ratio. On the contrary, changes after exercise of moderate (60%) intensity (lowering of apo-B containing lipoproteins in healthy subjects and patients and elevation of apo-A1 concentration in healthy subjects) were antiatherogenic.

Tolerance to dietary fat was evaluated by oral fat load test (consumption of 639+/-7 ml of 20% cream after fast). In subjects without CHD reaction of lipid transport system to fat load was characterized by lowered total, low density lipoprotein cholesterol, apolipoprotein apo B and apo B/apo A-1 ratio, lowered or unchanged triglycerides, stable high density lipoprotein cholesterol level at the background of apo A-1 elevation by 6-th hour after load.
