Spousal body weight concordance and the impact of spouse overweight on death risk: data form a 27-year cohort prospective study

Aim. To study the interdependence of spousal body mass and influence of spouse overweight on the death risk according to the 27-year cohort prospective study.Material and methods. We examined a random household sample (n=1546; married couples, 427). Overweight frequency among spouses was studied on the first stage of the study (1988-1991). In 2002-2005 (stage II), the examination was repeated and overweight dynamics were studied. In 2015 (stage III), we analyze mortality rates and significance of overweight and spousal overweight for the mortality risk formation. Overweight was detected in people with body mass index ≥25 kg/m2. Two hundred deaths were recorded during 27-year follow-up. Vital status was established for 97% of observed persons.Results. Overweight was detected in 61,1% of men who lived with overweight wife and in 45% of men whose wife had normal body mass (p<0,01). Overweight was diagnosed more often in women whose husband also had overweight comparing with women who lived with normal weight husband (76,2% vs 61,7%; p<0,001). The risk of overweight formation among individuals whose spouse’s body mass increased from norm to overweight was in 3,04 times higher than in persons whose spouse had a stable normal body mass and in 2,2 times higher than in participants whose spouse had overweight on study stages I and II. Relative risk of mortality in men who lived with overweight wife was 2,07.Conclusion. 1) We found the body mass concordance in spouses. 2) The average body mass index in men and women who lived with overweight spouse is higher than in men and women whose spouse had a normal body mass. 3) Interdependence of spousal body mass was revealed in dynamics. 4) Spousal overweight is an independent predictor of premature mortality in men

Dynamics of the bioclimatic potential of agroecological zones of the Altai Territory in the conditions of modern climatic and anthropogenic changes

The steppe zone is characterized by high dynamism of environmental conditions including sharp climatic fluctuations that affect both the possibilities of agriculture and the state of steppe landscapes. Further development of agriculture without taking into account changing climatic and environmental factors increases risks both for steppe ecosystems and for the sustainability of agriculture. The field production of the agro-climatic zones of the Altai Territory is characterized by the high variability of gross yields associated with the dynamics of precipitation, air temperature, and soil fertility. Under the current conditions, the analysis of the temporal and spatial dynamics of bioclimatic potential is of high practical importance for the development and implementation of adaptive agricultural technologies. A retrospective analysis was carried out and a modern bio-climatic characteristic of model territories representing various agroecological zones was compiled for this purpose. The object of research was data on average daily, average monthly, and average annual air temperatures, the level of precipitation, the water vapor pressure, and relative humidity. Statistical processing of analytical data was carried out in Excel. Calculations revealed significant temporal and spatial dynamics of the BCP. Spatially, it is characterized by a significant decrease in a north-western orientation. The lowest average values, 1.71-1.81 units, were observed in the Kulunda and Rubtsovskaya agroecological zones, with a coefficient of variation of more than 20.0%. The Zarinskaya and Aleyskaya agroecological zones were characterized by the highest values of BCP, and the Predgornaya zone presented maximum values of BCP, at the level of 2.70 units with high stability. Temporally, the BCP of the Zarinskaya, Kulunda, and Priobskaya agroclimatic zones is characterized by a negative trend; in other zones, its almost zero balance is noted. A sufficiently expressed difference in the BCP of various agroecological zones has an impact on the realization of the biological potential of cultivated crops. Analysis of the level of development of the vegetative mass of spring wheat by determining NDVI confirmed this assumption. For a systematic assessment of the influence of climatic and anthropogenic factors on the production process of field crops and the development of measures for the rational use of agricultural landscapes, it is advisable to determine the potential yield according to the BCP, determine the degree of its implementation in the economic harvest and justify techniques for leveling limiting factors in agrotechnology of individual agroecological zones

Определение безвредности гликопептидов молочнокислых бактерий на лабораторных животных

The study of acute toxicity and allergenity glycopeptides lactic acid bacteria in mice and rabbits. At the present level of physical, chemical and biological pollution of the environment, domestic and farm animals in no less, if not more than people, suffer from secondary induced immunodeficiency - an imbalance in the normal functioning of the immune system. This leads to a significant reduction in the overall resistance of the animal to various diseases of a viral and bacterial nature. The normal functioning of the animal's immune system can be restored with the help of immunomodulators, the active principle of which is the glycopeptide synthesized from natural components - a universal structural fragment of the lactic acid bacteria cell membrane that interacts with the immune system of the animal organism.Изучение острой токсичности и аллергености гликопептидов молочнокислых бактерий на мышах и кроликах. При современном уровне физического, химического и биологического загрязнения окружающей среды домашние и сельскохозяйственные животные не в меньшей, если не в большей, степени чем люди, страдают от вторично индуцированного иммунодефицита - разбалансировки нормального функционирования иммунной системы. Это приводит к существенному снижению общей сопротивляемости организма животного к различным заболеваниям вирусной и бактериальной природы. Восстановить нормальное функционирование иммунной системы животного можно с помощью иммуномодуляторов, действующим началом которых является синтезированный из природных компонентов гликопептид - универсальный структурный фрагмент оболочки клеток молочнокислых бактерий, взаимодействующий с иммунной системой животного организма

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Measurement of χ c1 and χ c2 production with s√ = 7 TeV pp collisions at ATLAS

The prompt and non-prompt production cross-sections for the χ c1 and χ c2 charmonium states are measured in pp collisions at s√ = 7 TeV with the ATLAS detector at the LHC using 4.5 fb−1 of integrated luminosity. The χ c states are reconstructed through the radiative decay χ c → J/ψγ (with J/ψ → μ + μ −) where photons are reconstructed from γ → e + e − conversions. The production rate of the χ c2 state relative to the χ c1 state is measured for prompt and non-prompt χ c as a function of J/ψ transverse momentum. The prompt χ c cross-sections are combined with existing measurements of prompt J/ψ production to derive the fraction of prompt J/ψ produced in feed-down from χ c decays. The fractions of χ c1 and χ c2 produced in b-hadron decays are also measured
