Production cross sections of Rh and Ag in proton bombed Pb target with 400 MeV energy.

The accelerator-driven subcritical system (ADS) is a competitive option for next-generation nuclear energy systems. Production cross sections of long-lived residual radioactive nuclides in a proton-nuclide reaction are basic quantities for the calculation of accumulated radioactivity in the use of ADS systems. This work presents the production cross sections of Rh and Ag in a natural lead (Pb) target activated by 400 MeV protons.

[The relationship between the relative length of leukocyte telomeres and mtDNA copy number and acute coronary syndrome in a 15-year follow-up.].

to study the association of relative leukocyte DNA telomere length with death from natural causes during a 15-year follow-up in a middle-aged and elderly Siberian population. Study of the association of the relative length of leukocyte telomeres (LTL) with fatal outcomes during a 15-year follow-up of a random population sample formed in 2003-2005 (n=9 360, 45-69 years old, Novosibirsk, HAPIEE project). The main group included the persons died from natural causes (except external) without a previous history of CVD and cancer (n=609); controls were stratified by sex and age (n=799).

[Cognitive functions and modifiable risk factors for chronic non-communicable diseases in ageing in a Russian population sample.].

We aimed to investigate the relationship between the indicators of cognitive functions (CF) and modifiable risk factors for chronic non-communicable diseases (NCD) in a cross-sectional analysis in the urban Russian population sample aged 55-84 years. The study investigated a random sample of 3 153 people (men and women 55-84 years old) from a general population cohort of Novosibirsk residents; a sample was examined within the international project HAPIEE. The study protocol included standardized neuropsychological tests (quantitative assessment of memory, semantic verbal fluency, attention and processing speed) and standardized assessment of risk factors, history and treatment of cardiovascular disease and NCD.

The Determinants of the 13-Year Risk of Incident Atrial Fibrillation in a Russian Population Cohort of Middle and Elderly Age.

Atrial fibrillation (AF) is the most common arrhythmia and a predictor of the complications of atherosclerotic cardiovascular diseases (ASCVDs), particularly thromboembolic events and the progression of heart failure. We analyzed the determinants of the 13-year risk of incident AF in a Russian population cohort of middle and elderly age. A random population sample ( = 9360, age 45-69 years) was examined at baseline in 2003-2005 and reexamined in 2006-2008 and 2015-2017 in Novosibirsk (the HAPIEE study).

Social networks and cognitive function in older adults: findings from the HAPIEE study.

Background: Social networks are associated with better cognitive health in older people, but the role of specific aspects of the social network remains unclear. This is especially the case in Central and Eastern Europe. This study examined associations between three aspects of the social network (network size of friends and relatives, contact frequency with friends and relatives, and social activity participation) with cognitive functions (verbal memory, learning ability, verbal fluency, processing speed, and global cognitive function) in older Czech, Polish, and Russian adults.
