Subjective Well-Being of Russian Female Personnel as an Indicator of Socio-Psychological Age

The present work is theoretical and empirical research on the socio-psycho- logical age of female personnel at enterprises with different organizational cultures. The main indicators of socio-psychological age include the level of commitment to organizational values, readiness for organizational changes, involvement in labor activity, and fatigue. The respondents are female employees of two large industrial enterprises. The female personnel working in a market-hierarchical type of organizational culture with an expressed innovative component reflect characteristics of a younger socio-psychological age while those working at an enterprise with a hierarchical-clan type of organizational culture display characteristics of a more senior socio-psychological age

Features of Chronic Bronchitis in Different Age Groups

Background: Lung diseases are assuming greater relevance and importance today. Chronic bronchitis is a self-nosology, which may precede the development of COPD, the importance of which can hardly be overestimated. The main problem in this disease is caused by late diagnosis and treatment due to the delay by patients in seeking medical help. The aim of the work was to study the distribution and exposure to tobacco smoke, especially chronic bronchitis, depending on various factors, including age. Methods: We examined 1779 persons, including 855 men and 924 women. The mean age of the population was 35.83±8.3 years. We conducted surveys and spirometry. The outcome was assessed after a bronchodilation test was performed with salbutamol 400 mcg. We performed all statistical analysis using software package Statistica 10. Results: We identified chronic bronchitis in 9.2% of the cases in the group of younger individuals and in 14.9% of the cases in the group of older individuals, during the active detection of chronic bronchitis using questionnaires. The prevalence of cigarette smoking was slightly higher among the younger (39.5%) than the older persons (33.6%); the frequency of smoking in a group of chronic bronchitis was reliably higher. Also, in this group, the performance spirometry reliably decreased. Conclusions: Outpatient survey is an effective method of identifying chronic bronchitis. Smoking is a major risk factor in the group of young respondents and the prevalence of smoking is inversely related to the education level of the respondents, regardless of age. As the decline in the Forced Expiratory Volume (FEV1 and FEV1/FVC) is the main criterion diagnosis of COPD, it revealed significant declines in the FEV1 of the younger smoking individuals, which may help to predict the development of COPD in the older age group

Genetically engineered CD80–pMHC-harboring extracellular vesicles for antigen-specific CD4+ T-cell engagement

The identification of low-frequency antigen-specific CD4+ T cells is crucial for effective immunomonitoring across various diseases. However, this task still encounters experimental challenges necessitating the implementation of enrichment procedures. While existing antigen-specific expansion technologies predominantly concentrate on the enrichment of CD8+ T cells, advancements in methods targeting CD4+ T cells have been limited. In this study, we report a technique that harnesses antigen-presenting extracellular vesicles (EVs) for stimulation and expansion of antigen-specific CD4+ T cells. EVs are derived from a genetically modified HeLa cell line designed to emulate professional antigen-presenting cells (APCs) by expressing key costimulatory molecules CD80 and specific peptide–MHC-II complexes (pMHCs). Our results demonstrate the beneficial potent stimulatory capacity of EVs in activating both immortalized and isolated human CD4+ T cells from peripheral blood mononuclear cells (PBMCs). Our technique successfully expands low-frequency influenza-specific CD4+ T cells from healthy individuals. In summary, the elaborated methodology represents a streamlined and efficient approach for the detection and expansion of antigen-specific CD4+ T cells, presenting a valuable alternative to existing antigen-specific T-cell expansion protocols

Genes flanking Xist in mouse and human are separated on the X chromosome in American marsupials

X inactivation, the transcriptional silencing of one of the two X chromosomes in female mammals, achieves dosage compensation of X-linked genes relative to XY males. In eutherian mammals X inactivation is regulated by the X-inactive specific transcript (Xist), a cis-acting non-coding RNA that triggers silencing of the chromosome from which it is transcribed. Marsupial mammals also undergo X inactivation but the mechanism is relatively poorly understood. We set out to analyse the X chromosome in Monodelphis domestica and Didelphis virginiana, focusing on characterizing the interval defined by the Chic1 and Slc16a2 genes that in eutherians flank the Xist locus. The synteny of this region is retained on chicken chromosome 4 where other loci belonging to the evolutionarily ancient stratum of the human X chromosome, the so-called X conserved region (XCR), are also located. We show that in both M. domestica and D. virginiana an evolutionary breakpoint has separated the Chic1 and Slc16a2 loci. Detailed analysis of opossum genomic sequences revealed linkage of Chic1 with the Lnx3 gene, recently proposed to be the evolutionary precursor of Xist, and Fip1, the evolutionary precursor of Tsx, a gene located immediately downstream of Xist in eutherians. We discuss these findings in relation to the evolution of Xist and X inactivation in mammals

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.

Psychological-pedagogical Aspects of Solving Social-cultural Problems of Socialization among Gifted Preschoolers

Modern Russian and foreign academic literature offers a significant number of authorial approaches which reveal gifted children’s peculiarities and difficulties, features of their personal and social development.Analyzing difficulties in social development that gifted children face, the authors suppose that the category of children have peculiarities and even complications in duly solutions of socialization problems at any age, which frequently leads to victimization. The argumentation is based on A. Mudric’s theory that necessitates duly solution of the three groups of socialization problems: natural-cultural, social-cultural and social-psychological. Their retarded solution or lack of the solution may cause a victimization process, thus preventing a gifted child from having successful future with achieving set goals and built according to the “Winner” pattern. A child with great expectations may come to the pattern “Not a Winner” or even “Loser” (Berne, 2015). Solving the above mentioned socialization tasks matters at any age stage starting from preschool period. The indicators of solving socialization problems were formulated. Each group has its own features and figures of successful personal and social development of a child. The authors consider the following indicators of solving social-cultural socialization problems: awareness of ethical norm, independence, interests and hobbies. Empirical data were obtained via interviewing and testing preschool children aged 5-7 years old (senior and preparatory groups) from 7 preschool educational organizations in Kostroma (n=186); and through questioning and testing parents and pedagogue
