Remodeling Of Extracellular Matrix

Introduction. The peptide hormone relaxin, which is produced by cells of the corpus luteum during and outside pregnancy, has a huge number of clinically significant effects, mediating many biological mechanisms, including antifibrotic, vasodilatory, angiogenic, anti-inflammatory and antiapoptotic effects.Purpose of the study: based on the study of modern literature data, to analyze the results of scientific research, representing the current system of views on the physiological and pathophysilogical effects of relaxin.Materials and methods. A study f scientific publications for the period from 2005 to 2020 in e PubMed and Elibrary databases was carried out using the keywords: relaxin, pregnancy, relaxin signaling pathway, reproductive system, extracellular matrix.Results and Discussion. The study of modern views on the physiology of relaxin has shown that this hormone mediates its effects by binding to the specific receptor RXFP1, which is localized in a large number of reproductive nonproductive tissues. Relaxin performs many functions related to the remodeling of the extracellular matrix and vasculature. The main uterotropic effects of this peptide include stimulation of growth and vascularization of the uterus, remodeling of extracellular matrix components, and regulation of vascular endothelial growth factor in preparation for implantation.Conclusion. The progress of the last decade in understanding the biochemistry of the hormone relaxin has formed the basis for a deeper penetration into all the variety of its physiological roles. The participation of relaxin in the mechanisms of relaxation of the myometrium during pregnancy, remodeling of the connective tissue of target organs in the antenatal period creases its potential clinical significance. The prospect of a possible therapeutic use of relaxin preparations in stimulating antenatal transformation of the cervix, in vitro fertilization, therapy of preeclampsia, acute heart failure and myocardial ischemia turns it into a potential therapeutic agent for these pathological conditions.

The Impact

Purpose The increasing use of non-tenure employment contracting as a cost savings and/or management flexibility increasing mechanism in colleges and universities raises concerns about the impact of this strategy on other aspects of the higher education system. The purpose of this paper is to document reduced research productivity at a university that uses rolling contracts in comparison to research productivity at another university in the same state university system in the USA that uses tenure track contracting. Design/methodology/approach Negative binomial regression analysis allows investigation of the primary variable of interest (appointment type) while controlling for other factors that may also affect research productivity. Findings The findings suggest that non-tenure track employment contracting may have other long-term implications for institutions of higher education that warrant consideration. Originality/value No prior study has investigated the topic of comparative research productivity in business schools using this methodology or data source.

ABSTRACTHeteroresistance refers to the presence, within a large population of antimicrobial-susceptible microorganisms, of subpopulations with lesser susceptibilities. Ceftaroline is a novel cephalosporin with activity against methicillin-resistantStaphylococcus aureus(MRSA). The aim of this study was to detect the prevalence of ceftaroline heteroresistancein vitroin a select group ofS. aureusstrains. There were 57 isolates selected for evaluation, 20 MRSA, 20 vancomycin-intermediateS. aureus(VISA), 7 daptomycin-nonsusceptibleS. aureus(DNSSA), 6 linezolid-nonsusceptibleS. aureus(LNSSA), and 4 heteroresistant VISA (hVISA) isolates. MICs and minimal bactericidal concentrations were determined using the broth microdilution method according to CLSI guidelines. All of the isolates were analyzed by pulsed-field gel electrophoresis. The staphylococcal cassette chromosomemecelement (SCCmec) types were determined by a multiplex PCR. Population analysis profiles (PAPs) were performed to determine heteroresistance for all of the isolates using plates made by adding various amounts of ceftaroline to brain heart infusion agar. The frequencies of resistant subpopulations were 1 in 104to 105organisms. We determined that 12 of the 57 (21%) isolates tested were ceftaroline-heteroresistantS. aureus(CHSA). CHSA occurred among strains with reduced susceptibilities to vancomycin, daptomycin, and linezolid but occurred in none of the USA-300 isolates tested. Evaluation of the heteroresistant strains demonstrated that the phenotype was unstable. Further studies are needed to determine whether CHSA has a role in clinical failures and to determine the implications of our study findings.

Background. In previous studies, people’s knowledge of reproductive health and infertile women’s psychological states was surveyed in several countries. However, there has been limited information concerning the psychological states of infertile women seeking treatment and the outcomes of in vitro fertilization (IVF) in China.Methods. Infertile women were asked to complete short questionnaires on the day that their oocytes were retrieved; these questionnaires covered the durations of their infertility, levels of education, sources of pressure, and psychological states. Data concerning IVF outcomes were provided by embryologists and clinicians. The correlations between the duration of infertility and educational level, psychological state and education level, and psychological state and outcome of IVF were analyzed in the cohort study.Results. The duration of infertility in more than half of the females was longer than 5 years. Compared with less-educated women, women with higher levels of education sought treatment earlier and their rates of depressive symptoms were lower. There is an association between negative emotions and outcome of IVF.Conclusions. The survey of the situations of infertile women seeking IVF treatment in China indicates the importance of popularizing knowledge concerning reproductive health. Improving medical conditions, reducing the costs of treatment, and developing social culture will aid in relieving the stress of infertile women and improving assisted reproductive treatment.

Aim. To assess the main indicators of the initial reproductive health of parents, somatic health of the mother and their impact on the health of children born with singleton pregnancy ART. Materials and methods. The study included all newborn infants from singleton ART who were born at the Avicenna Medical Center (Novosibirsk) over the period 2006–2017 (n=409) and their parents (n=818). All stages of overcoming infertility (from the moment the parents go to the clinic to the birth of children) are considered in the context of one center, in a relatively homogeneous social group, with ensuring continuity at all stages. The average experience of infertility in couples was 7.2±0.2 years. The groups were formed depending on the type of infertility and the method of assisted reproductive technologies (ART) used: 205 children were born using in vitro fertilization (IVF), 204 children were born using the method of Intracytoplasm Sperm Injection (ICSI). The method of IVF and transfer of embryos into the uterine cavity is more often used in women with tuboperitoneal, endocrine types of infertility (premature ovarian failure syndrome), as well as in infertility associated with endometriosis. More serious reproductive problems (severe forms of male infertility, a combination of several types of infertility) in most cases lead to the use of more serious technological methods of ART, in particular, the addition of IVF and embryo transfer by the ICSI method. The reasons underlying infertility in most cases lead not only to the choice of the ART method, but also determine the characteristics of the course of pregnancy and the development of the intrauterine fetus. Pregnancy in the IVF group is significantly more often complicated by the threat of termination and premature birth, while ICSI pregnancy more often leads to impaired development of the intrauterine fetus. Conclusion. Features of medical support of women during the preparation for ART and, of course, during pregnancy, with a comprehensive, interdisciplinary correction of expected complications in each of the groups, will improve the perinatal outcomes of induced pregnancy and will contribute to the birth of healthy offspring.

Introduction. The use of assisted reproductive technology in a situation of a demographic crisis can contribute to an increase in the birth rate among childless parents. The paper is of relevance as there is a need for a sociological analysis of the youth’s attitudes towards the use of assisted reproductive technology. The purpose of the article is to reveal significant factors affecting the youth’s attitudes towards assisted reproductive technology and its application, based on the results of a case study conducted among young people residing in the city of Saransk. Materials and Methods. The study used the methods of analysis, comparison and correlation. The data of a pilot survey conducted among young people residing in the city of Saransk and statistics were used as the empirical base of the study. The data were collected on the basis of the methodology developed by the authors according to quota sampling (by sex, age and place of residence). Results. The study has revealed the correlation between the respondents’ awareness of assisted reproductive technology and their level of education, age and marital status. It has been established that those respondents who took advantage of assisted reproductive technology, more often used such methods as in vitro fertilization, intracytoplasmic sperm injection and surrogacy. The authors have formulated proposals on the need for the state to increase funding for the assisted reproductive technology programs, when it concerns reproductive health, to allocate quotas, ensuring the availability of the technology for the enforcement of the reproductive rights in society, as well as to inform the public about new types of assisted reproductive technology. Discussion and Conclusion. The results of the study can be used by the authorities, staff of reproductive health centers and in vitro fertilization clinics to develop and plan assisted reproductive technology programs, for conducting monitoring studies on the use of assisted reproductive technology. Prospects for the study are associated with conducting further in-depth qualitative research on parents using assisted reproductive technology.
