Comboridity of chronic obstructive pulmonary disease and cardiovascular diseases: general factors, pathophysiological mechanisms and clinical significance

Currently, the comorbidity (combination) of chronic obstructive pulmonary disease (COPD) and cardiovascular diseases (CVD) is an important problem for the health care. This is due to the high prevalence and continuing growth of these pathologies. CVD and COPD have common risk factors and mechanisms underlying their development and progression: smoking, inflammation, sedentary lifestyle, aging, oxidative stress, air pollution, and hypoxia. In this review, we summarize the current knowledge related to the prevalence and frequency of cardiovascular diseases in people with COPD and the mechanisms that underly their coexistence. The implications for clinical practice, in particular the main problems of diagnosis and treatment of COPD/CVD comorbidity, are also discussed

The influence of agrotechnologies of organic farming on the content of humus, phosphorus and potassium in the soil

Abstract Organic agriculture is becoming an increasingly popular direction in modern agriculture. At the same time, some researchers and practitioners still have doubts about the ability of this technology to maintain the balance of nutrients in the soil. The article is a contribution to the study of the influence of long-term organic farming on agrochemical soil parameters. The aim of the study was to study the influence of organic farming technology on the content of humus, mobile forms of potassium and mobile forms of phosphorus in the soil of the most important components for fertility – humus, mobile forms of potassium and mobile forms of phosphorus in the non-carbonate chernozems of Western Siberia. The chernozems of Western Siberia are characterized by a high content of humus and nutrients, have optimal properties for agricultural crops. A statistically processed comparison of the quantitative content of humus, mobile forms of potassium and mobile forms of phosphorus in fields with long-term use of organic farming technology, and in similar fields where this technology was not used, was carried out. The article includes a brief geographical, geological, climatic characteristics of the place of the experiment, a description of the applied agricultural technologies and fertilizers. As a result, it was found that the use of organic farming technology has a positive effect on the state of soils, which is confirmed by an increase in the content of humus, mobile forms of potassium and mobile forms of phosphorus

LC-MS Method Development for Simultaneous Determination of Trans-3′-hydroxycotinine and Three Mercapturic Acids in Urine

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. The negative impact of tobacco smoke on the human body is due to a wide range of harmful substances including volatile organic compounds (VOCs). Some VOCs of tobacco smoke metabolize in human organism into mercapturic acids (MAs). The determination of the amount of MAs in readily available biological fluids, for example in urine, allows to assess the level of exposure of these VOCs in a particular person. It is useful to assess the impact of individual VOCs on the body together with the assessment of the intake of nicotine. The intake of nicotine can be determined by the content of its metabolites in the urine, in particular by the content of trans-3′-hydroxycotinine (tH-Cot). A joint assessment of the concentrations of trans-3′-hydroxycotinine and MAs in urine allows obtaining selective information about effects of different VOCs and nicotine on the smoker’s body. We have developed a liquid chromatography–mass spectrometry (LC-MS) method for simultaneous quantifying of tH-Cot and three MAs: N-Acetyl-S-(3-hydroxypropyl)cysteine (HPMA), N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (HMPMA), N-Acetyl-S-(2-cyanoethyl)-L-cysteine (CEMA). We used this method to quantify the levels of MAs and tH-Cot in the urine of a group of 15 smokers just before and 5 days after smoking cessation. For all studied compounds, we have found statistically significant changes in concentration on the fifth day of smoking cessation. The method developed can be used to jointly assess the levels of exposure to nicotine and VOCs in the study of various tobacco products

Shotgun metagenomic data on the human stool samples to characterize shifts of the gut microbial profile after the Helicobacter pylori eradication therapy

© 2017 The Authors The shotgun sequencing data presented in this report are related to the research article named “Gut microbiome shotgun sequencing in assessment of microbial community changes associated with H. pylori eradication therapy” (Khusnutdinova et al., 2016) [1]. Typically, the H. pylori eradication protocol includes a prolonged two-week use of the broad-spectrum antibiotics. The presented data on the whole-genome sequencing of the total DNA from stool samples of patients before the start of the eradication, immediately after eradication and several weeks after the end of treatment could help to profile the gut microbiota both taxonomically and functionally. The presented data together with those described in Glushchenko et al. (2017) [2] allow researchers to characterize the metagenomic profiles in which the use of antibiotics could result in dramatic changes in the intestinal microbiota composition. We perform 15 gut metagenomes from 5 patients with H. pylori infection, obtained through the shotgun sequencing on the SOLiD 5500 W platform. Raw reads are deposited in the ENA under project ID PRJEB21338

First Results from the AMoRE-Pilot neutrinoless double beta decay experiment

The Advanced Molybdenum-based Rare process Experiment (AMoRE) aims to search for neutrinoless double beta decay (0$\nu\beta\beta$) of $^{100}$Mo with $\sim$100 kg of $^{100}$Mo-enriched molybdenum embedded in cryogenic detectors with a dual heat and light readout. At the current, pilot stage of the AMoRE project we employ six calcium molybdate crystals with a total mass of 1.9 kg, produced from $^{48}$Ca-depleted calcium and $^{100}$Mo-enriched molybdenum ($^{48\textrm{depl}}$Ca$^{100}$MoO$_4$). The simultaneous detection of heat(phonon) and scintillation (photon) signals is realized with high resolution metallic magnetic calorimeter sensors that operate at milli-Kelvin temperatures. This stage of the project is carried out in the Yangyang underground laboratory at a depth of 700 m. We report first results from the AMoRE-Pilot $0\nu\beta\beta$ search with a 111 kg$\cdot$d live exposure of $^{48\textrm{depl}}$Ca$^{100}$MoO$_4$ crystals. No evidence for $0\nu\beta\beta$ decay of $^{100}$Mo is found, and a upper limit is set for the half-life of 0$\nu\beta\beta$ of $^{100}$Mo of $T^{0\nu}_{1/2} > 9.5\times10^{22}$ y at 90% C.L.. This limit corresponds to an effective Majorana neutrino mass limit in the range $\langle m_{\beta\beta}\rangle\le(1.2-2.1)$ eV

Gut Microbiome Shotgun Sequencing in Assessment of Microbial Community Changes Associated with H. pylori Eradication Therapy

© 2016, Springer Science+Business Media New York.Disturbance of intestinal microbiota content and functions often results in different pathological conditions. Pharmacotherapy including antibiotics use is one of the factors leading to dysbiosis. To evaluate the influence of antibiotics use on intestinal microbiota metagenomic profiles of stool, samples of 74 patients before and after Helicobacter pylori—eradication therapy—were analyzed. Evaluation of taxonomic diversity changes based on Shannon index and Bray-Curtis metrics allows to range patients according to mild, moderate, and severe risk of disturbance of intestinal microbiota pathological conditions

Food behavior as a factor of health

One of the theoretical foundations for improving student health is the correct nutritional behavior of a person and the right attitude to physical education. The physiological parameters of eating behavior are determined by the body's need for consumption and digestion of food, the state of homeostasis, which maintains the stability of its functional systems, including the digestive system. The psychological parameters of eating behavior are determined by the personal attitude to eating and its methods. Analysis of risk factors for the development of metabolic syndrome in students helps to include such innovative methods in the learning process at the university as ecologization of students' knowledge, increasing the actualization of physical education among students.Одной из теоретических основ улучшения здоровья студентов является правильное пищевое поведение человека и правильное отношение к физическому воспитанию. Физиологические параметры пищевого поведения определяются потребностью организма в потреблении и переваривании пищи и определяют нутритивный статус человека. Психологические параметры пищевого поведения определяются личным отношением к еде и её потреблению. Анализ факторов риска развития метаболического синдрома у студентов помогает включать такие инновационные методы в процесс обучения в ВУЗе, как экологизация знаний студентов, повышение актуализации физической культуры среди студентов
