Image of Presenter of Political Talk Show: on Problem of Gender Peculiarities

The study is done within actual direction of modern science - the gender linguistics. The article is devoted to the question of the communicative image of the TV presenters of political talk-show Vladimir Solovyov and Olga Skabeyeva. The results of a comparative analysis of the components of the public image of each media person are presented: appearance, communicative behavior, speech manners. It is shown that Solovyov and Skabeyeva have a bright, catchy, wistful image, and their similarities - leading position, business style in clothes, gestures system, categoricalness - are determined by the program format. It is proved that at the same time, communicative images of the presenters have a specific gender identity: Vladimir Solovyov’s image corresponds to stereotypical idea of a real man, while Olga Skabeyeva’s image combines both typically female (modesty, elegance, parity) and male characteristics (rationality, rigidity, hardness). Special attention is given to verbal behaviour that detects the individual characteristics of each media person. Vladimir Solovyov’s manner of speech can be characterized as assertive, poly-stylistic, management one. The authors argue that the dominant for this presenter is a strategy of self-presentation, while the main intention can be defined as the retention of communicative leadership. The general speech style of Olga Skabeyeva can be described as aggressive, but the presenter purely uses female methods of mitigating the conflict. It is proved that the communicative style of the presenter is not free from gender peculiarities of the personality

Macrophages in epicardial adipose tissue and serum NT-proBNP in patients with stable coronary artery disease

Coronary artery disease (CAD) is widely considered a chronic inflammatory disorder, and dysfunction of epicardial adipose tissue could be an important source of the inflammation. Amino-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) is a known marker of cardiovascular disorders of cardiac origin. Recent studies show that inflammatory stimuli may influence its secretion. Our purpose was to evaluate NT-proBNP serum concentration in relation to immune cell ratios in epicardial adipose tissue (EAT), and cytokine levels in the patients with stable CAD. Patients with stable CAD and heart failure classified into classes II–III, according to the New York Heart Association (NYHA) scale, scheduled for the coronary artery bypass graft (CABG) surgery, were recruited into the study (n = 10; 59.5 (53.0-65.0) y. o.; 50% males). The EAT and subcutaneous adipose tissue (SAT) specimens were harvested in the course of CABG surgery. Immunostaining with anti-CD68, anti-CD45, antiIL-1β and anti-TNFα monoclonal antibodies was performed to evaluate cell composition by differential counts per ten fields (400 magnification). Fasting venous blood was obtained from patients before CABG. Blood was centrifuged at 1500g, aliquots were collected and stored frozen at -40 °С until final analysis. Concentrations of NT-proBNP, IL-1β, IL-6, IL-10, TNFα were determined in serum samples by enzyme-linked immunosorbent assay (ELISA). We have found increased production of IL-1β and TNFα cytokines in EAT compared to SAT. Concentrations of NT-proBNP exceeded 125 pg/ml in 4 patients, and correlations between the CD68+ macrophage counts in both EAT and SAT samples (rs = 0.762; p = 0.010 and rs = 0.835; p = 0.003, respectively). NT-proBNP levels showed positive relations with CD45+ leukocyte counts (rs = 0.799; p = 0.006), and with IL-1β+ cell numbers (rs = 0.705; p = 0.023) in EAT samples only. As for the serum biomarkers, NT-proBNP levels showed negative correlation with fasting glucose levels (rs = -0.684; p = 0.029), and positive correlation with serum IL-6 concentrations (rs = 0.891; p = 0.001). Increased serum concentrations of NT-proBNP in CAD patients correlate with accumulation of macrophages in EAT, which is associated with increased production of IL-1β in EAT and correlates with some metabolic parameters

Evolution of oxygen-ion and proton conductivity in Ca-Doped Ln2Zr2O7 (Ln = Sm, Gd), located near pyrochlore fluorite phase boundary

Sm2-xCaxZr2O7-x/2 (x = 0, 0.05, 0.1) and Gd2-xCaxZr2O7-x/2 (x = 0.05, 0.1) mixed oxides in a pyrochlore-fluorite morphotropic phase region were prepared via the mechanical activation of oxide mixtures, followed by annealing at 1600 ?C. The structure of the solid solutions was studied by X-ray diffraction and refined by the Rietveld method, water content was determined by thermogravimetry (TG), their bulk and grain-boundary conductivity was determined by impedance spectroscopy in dry and wet air (100-900 ?C), and their total conductivity was measured as a function of oxygen partial pressure in the temperature range: 700-950 ?C. The Sm2-xCaxZr2O7-x/2 (x = 0.05, 0.1) pyrochlore solid solutions, lying near the morphotropic phase boundary, have proton conductivity contribution both in the grain bulk and on grain boundaries below 600 ?C, and pure oxygen-ion conductivity above 700 ?C. The 500 ?C proton conductivity contribution of Sm2-xCaxZr2O7-x/2 (x = 0.05, 0.1) is ~ 1 ? 10-4 S/cm. The fluorite-like Gd2-xCaxZr2O7-x/2 (x = 0.1) solid solution has oxygen-ion bulk conductivity in entire temperature range studied, whereas proton transport contributes to its grain-boundary conductivity below 700 ?C. As a result, of the morphotropic phase transition from pyrochlore Sm2-xCaxZr2O7-x/2 (x = 0.05, 0.1) to fluorite-like Gd2-xCaxZr2O7-x/2 (x = 0.05, 0.1), the bulk proton conductivity disappears and oxygen-ion conductivity decreases. The loss of bulk proton conductivity of Gd2-xCaxZr2O7-x/2 (x = 0.05, 0.1) can be associated with the fluorite structure formation. It is important to note that the degree of Ca substitution in such solid solutions (Ln2-xCax)Zr2O7-? (Ln = Sm, Gd) is low, x < 0.1. In both series, grain-boundary conductivity usually exceeds bulk conductivity. The high grain-boundary proton conductivity of Ln2-xCaxZr2O7-x/2 (Ln = Sm, Gd; x = 0.1) is attributable to the formation of an intergranular CaZrO3-based cubic perovskite phase doped with Sm or Gd in Zr sublattice. ? 2019 by the authors.371C-9F16-EBDE | Eduarda GomesN/

T regulatory lymphocytes and FoxP3 nuclear translocation in various adipose tissue depots in patients with coronary artery disease

T regulatory lymphocytes (Treg) are present is adipose tissue. Their frequency, as well as the level of FoxP3 nuclear translocation, in epicardial and thymus adipose tissue remains unexplored. Properties of adiposeresident Tregs may be of high significance in patients with coronary artery disease as potential pathophysiological factor in the development of atherosclerosis. The aim of the study was to compare frequency of FoxP3+Tregs and FoxP3 nuclear translocation in epicardial, thymus, subcutaneous adipose tissue and peripheral blood in patients with coronary artery disease. A pilot study was conducted in 11 patients with coronary artery disease scheduled for the coronary artery bypass graft surgery after prior selective coronary angiography. Frequency of CD4+CD25hiFoxP3+ and CD4+CD25loFoxP3+ lymphocytes and FoxP3 nuclear translocation were evaluated by imaging flow cytometry in peripheral blood and in stromal vascular fraction of epicardial, subcutaneous and thymus adipose tissue. Frequencies of CD4+CD25hiFoxP3+ and CD4+CD25loFoxP3+ lymphocytes were higher in epicardial adipose tissue compared to blood (3 and 5 times higher, p = 0.020); CD4+CD25loFoxP3+ cells frequency in subcutaneous adipose tissue was 4 times higher than in blood (p = 0.028). The level of FoxP3 nuclear translocation was the highest in blood and decreased in epicardial, subcutaneous and thymus adipose tissue (p = 0.020 both for CD4+CD25hiFoxP3+ and CD4+CD25loFoxP3+ lymphocytes). Frequency of CD4+CD25loFoxP3+ cells was directly related to age in thymus (rs = 0.818; p = 0.002), and inversely in epicardial adipose tissue (rs = -0.618; p = 0.043). Frequencies of CD4+CD25hiFoxP3+ and CD4+CD25loFoxP3+ with FoxP3 nuclear translocation in subcutaneous adipose tissue negatively correlated with age (rs = -0.827; p = 0.002 and rs = -0.648; p = 0.031, respectively). Frequency of CD4+CD25loFoxP3+ cells with FoxP3 nuclear translocation in thymus adipose tissue negatively correlated with waist-to-hip ratio (rs = -0.700; p = 0.016). The severity of atherosclerosis was related only to the frequency of CD4+CD25loFoxP3+ cells in subcutaneous adipose tissue (rs = -0.655; p = 0.029). Thus, epicardial and subcutaneous adipose tissue are enriched with Tregs, but factors that influence Treg accumulation and FoxP3 nuclear translocation in these fat depots may be different. The obtained results may further be used for personalized immunomodulatory therapy in patients with atherosclerosis

Protocol for the perfusion and angiography imaging sub-study of the Third International Stroke Trial (IST-3) of alteplase treatment within six-hours of acute ischemic stroke

RATIONALE: Intravenous thrombolysis with recombinant tissue Plasminogen Activator improves outcomes in patients treated early after stroke but at the risk of causing intracranial hemorrhage. Restricting recombinant tissue Plasminogen Activator use to patients with evidence of still salvageable tissue, or with definite arterial occlusion, might help reduce risk, increase benefit and identify patients for treatment at late time windows. AIMS: To determine if perfusion or angiographic imaging with computed tomography or magnetic resonance help identify patients who are more likely to benefit from recombinant tissue Plasminogen Activator in the context of a large multicenter randomized trial of recombinant tissue Plasminogen Activator given within six-hours of onset of acute ischemic stroke, the Third International Stroke Trial. DESIGN: Third International Stroke Trial is a prospective multicenter randomized controlled trial testing recombinant tissue Plasminogen Activator (0·9 mg/kg, maximum dose 90 mg) started up to six-hours after onset of acute ischemic stroke, in patients with no clear indication for or contraindication to recombinant tissue Plasminogen Activator. Brain imaging (computed tomography or magnetic resonance) was mandatory pre-randomization to exclude hemorrhage. Scans were read centrally, blinded to treatment and clinical information. In centers where perfusion and/or angiography imaging were used routinely in stroke, these images were also collected centrally, processed and assessed using validated visual scores and computational measures. STUDY OUTCOMES: The primary outcome in Third International Stroke Trial is alive and independent (Oxford Handicap Score 0-2) at 6 months; secondary outcomes are symptomatic and fatal intracranial hemorrhage, early and late death. The perfusion and angiography study additionally will examine interactions between recombinant tissue Plasminogen Activator and clinical outcomes, infarct growth and recanalization in the presence or absence of perfusion lesions and/or arterial occlusion at presentation. The study is registered ISRCTN25765518

ФАКТОРЫ РИСКА, АССОЦИИРОВАННЫЕ С РОЖДЕНИЕМ ДЕТЕЙ С МАССОЙ ТЕЛА МЕНЕЕ 2500 Г: РЕЗУЛЬТАТЫ РЕТРОСПЕКТИВНОГО КОГОРТНОГО МНОГОЦЕНТРОВОГО ИССЛЕДОВАНИЯ

Background. Improving nursing methods of newborns with birth weight less than 2500 g resulted in an increase in the proportion of children at risk for the development of severe disabling conditions. Objective: Our aim was to investigate the risk factors of the mother, associated with the birth of a child with a birth weight less than 2500 g. Methods. In a retrospective cohort study included 572 children born to 566 mothers in 5 perinatal centers. Risk assessment was carried out taking into account birth weight (in groups of children with normal, low, very low and extremely low birth weight). Results. Sample of mothers (n = 489), whose children had birth weight     2500 g, characterized by a mean age of 31 (26; 35) years, the growth of 164 (159; 168) cm, weighing when registering for pregnancy 62 (53; 74) and 70 kg (60; 80) kg just before birth. Among the independent predictors of birth weight infants were allocated as follows: maternal education (higher/more), mother occupation (housewife/other), presence of chronic diseases, anemia during pregnancy, the threat of premature births, growth and weight of the mother’s body before birth, weight gain body during pregnancy, body mass index (BMI) when registering for antenatal care in pregnancy and before delivery. Conclusion. Identified risk factors for maternal birth weight infants, which can be used to stratify pregnant women at risk.Совершенствование  методов  выхаживания  новорожденных  с массой тела  при рождении  менее 2500  г привело к увеличению доли  детей группы риска по развитию тяжелых  инвалидизирующих  состояний.Цель  исследования: изучить факторы  риска со стороны матери, ассоциированные  с рождением  ребенка массой тела  менее 2500  г.Методы.  В ретроспективное  когортное  исследование  включены  данные 572  детей,  рожденных  от  566  матерей в 5 перинатальных центрах.
