Development of Parental Competence Trough Psychological and Pedagogical Support for Families in the Upbringing of Hearing-Impaired Children

Background. Te need for psychological and pedagogical support for families in the upbringing of hearing-impaired children makes it imperative to develop innovative methods and an efective model of interaction between the family and a special needs educational institution, to improve parental competence. Objective. To study the psychological content of parental competence (its cognitive, value-motivational; emotional and behavioral components) and to evaluate parental competence through psychological and pedagogical support for families in the upbringing of hearing-impaired children. Design. Eighty-seven families with hearing-impaired children from a special needs educational institution in Kursk, Russian Federation, participated in the experimental study. Te researchers took measurements at two time points, baseline and followup. At baseline, we made a diagnostic assessment of the psychological content of parental competence. At followup, we evaluated the development of parental competence resulting from the psychological and pedagogical support for these families. Results. Te cognitive component was characterized by predominant unanimity between the parents in the upbringing of hearing-impaired children, and a partnership relationship in communicating with them. Te emotional component was represented by the absence of difculties in understanding the causes of the children’s emotional state and an orientation towards the child’s emotional state during interactions or physical contact. Terminal values (such as health, happy family life) and instrumental values (such as responsibility, honesty) were predominant in the value-motivational component. Te behavioral component displayed a predominance of the authoritative style in upbringing, whereby parents realized their important role in the development of a child’s personality and recognized the right of children to self-development. At the same time, the authoritarian style was still signifcant. Conclusion. A model for psychological and pedagogical support of families in the upbringing of hearing-impaired children was developed, tested, and found to be efective

COMPARATIVE CHARACTERISTICS OF THE RHYTHM OF THE SEASONAL DEVELOPMENT OF SCUTELLARIA BAICALENSIS GEORGI IN THE NON-CHERNOZEM ZONE AND ON THE SOUTH COAST OF THE CRIMEA

Scutellaria baicalensis is a valuable medicinal plant and a protected species of the East Asian flora. Therefore, work on its introduction is underway in many regions of Russian Federation. Studying of the influence of meteorological factors on the phenology of the S. baicalensis in regions of Russian Federation with contrasting climatic conditions is important in grounds of climate change. Materials and methods. The object of the study is the population of the S. baicalensis biocollections of All-Russian Scientific Research Institute of Medicinal and Aromatic Plants and Nikitsky Botanical Garden. Meteorological indicators: sum of active temperatures, sum of precipitation. Statistical analysis: Tau-b-Kendall correlation coefficient. Results. The duration of the growing season in each region has little variability, independently of the weather conditions of the year. The interval between the onset of phenological phases in the Crimea was characterized by weaker variability than in the Non-Chernozem zone. A significantly smaller amount of active temperatures was required for the onset of phenological phases In the Non-Chernozem zone compared to the southern coast of Crimea. The difference in the average sum of active temperatures across the regions reached 1694.6°C by the end of the growing season. The amount of precipitation had sharp fluctuations in both regions and in all years of research. Conclusion. Secondary flowering, wide amplitudes of the duration of phenological phases and the growing season as a whole, the sum of active temperatures and precipitation indicate the ecological plasticity of the S. baicalensis and the availability of conditions for its cultivation in both regions

Competence of mosquitoes <i>Culex pipiens f.</i> molestus as carriers of West Nile virus under various temperature conditions

Introduction. The Culex pipiens mosquito is one of the proven vectors of the West Nile virus (WNV). Culex pipiens f. molestus (Cx. p. f. molestus) is a synanthropic, autogenous, widespread form of the species that can feed on a broad range of hosts, including humans. The temperature of the habitat of insects affects the potential for virus transmission, which determines the likelihood of them carrying the pathogen of West Nile fever. The goal is an experimental study of the temperature of the habitat of larvae on the competence of mosquitoes Cx. p. f. molestus as carriers of WNV. Materials and methods. We used a strain of the WNV (WNV_Volg601/18 genotype 2) and a laboratory culture of mosquitoes Cx. p. f. molestus. The concentration of the virus was detected by plaque formation using Vero cells. Insects were infected orally at the larval stage, with subsequent incubation at 20, 22 or 28C. 72 hours after the emergence of all adults from the pupae, the mosquitoes were immobilized by cold, the sex of imago was determined, the salivary glands were isolated from the females, and the presence of WNV in glandes and its titer were detected. Results. The titer of WNV sufficient to transmit the pathogen through the insect biting was observed in the salivary glands of insects kept at a temperature of 22 and 28C, with the virus titer rising with the temperature increasing. No virus was detected in the salivary glands of female insects kept at a temperature of 20C. Conclusion. Thus, it appears that the habitat temperature is an important factor limiting the replication and content of WNV in the salivary glands of Cx. p. f. molestus

The role of cannabinoid CB1 receptors in the antinociceptive and reparative actions of mesenchymal stem cells in rats with peripheral neuropathic pain

Abstract Mesenchymal stem cells (MSCs) can produce antinociceptive and reparative effects. Presumably, the MSCs‐induced antinociception may be partly due to the involvement of the endocannabinoid system. The study aimed to evaluate the antinociceptive and reparative effects of adipose‐derived MSCs (ADMSCs) upon pharmacological modulation of cannabinoid CB1 receptor in peripheral tissues or on ADMSCs' membranes in a rat model of peripheral neuropathy. ADMSCs were injected into the area of rat sciatic nerve injury (i) with no additional treatments, (ii) at the tissue CB1 receptor activation by endogenous agonist anandamide (AEA) or blockade with a selective AM251 antagonist; and (iii) preincubated with AEA or AM251. The evaluation of CB1 receptor activity involved analyzing nociceptive responses, gait parameters, and histology. Transplantation of ADMSCs upon activation of CB1 receptors, both on AMSCs' membranes or in the area of nerve injury, accelerated the analgesia and recovery of dynamic gait parameters, abolished static gait disturbances, and promoted the fastest nerve regeneration. Only blockade of CB1 receptors on ADMSCs shortened ADMSCs‐induced analgesia and decreased the number of preserved nerve fibers. CB1 receptors on ADMSCs significantly contribute to their pain‐relieving and tissue‐repairing capabilities by stimulating the growth factors secretion and suppressing the release of pro‐inflammatory cytokines. Peripheral CB1 receptors do not significantly influence ADMSC‐induced antinociception

Rationale, design, and baseline characteristics in Evaluation of LIXisenatide in Acute Coronary Syndrome, a long-term cardiovascular end point trial of lixisenatide versus placebo

BACKGROUND: Cardiovascular (CV) disease is the leading cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). Furthermore, patients with T2DM and acute coronary syndrome (ACS) have a particularly high risk of CV events. The glucagon-like peptide 1 receptor agonist, lixisenatide, improves glycemia, but its effects on CV events have not been thoroughly evaluated. METHODS: ELIXA (www.clinicaltrials.gov no. NCT01147250) is a randomized, double-blind, placebo-controlled, parallel-group, multicenter study of lixisenatide in patients with T2DM and a recent ACS event. The primary aim is to evaluate the effects of lixisenatide on CV morbidity and mortality in a population at high CV risk. The primary efficacy end point is a composite of time to CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina. Data are systematically collected for safety outcomes, including hypoglycemia, pancreatitis, and malignancy. RESULTS: Enrollment began in July 2010 and ended in August 2013; 6,068 patients from 49 countries were randomized. Of these, 69% are men and 75% are white; at baseline, the mean ± SD age was 60.3 ± 9.7 years, body mass index was 30.2 ± 5.7 kg/m(2), and duration of T2DM was 9.3 ± 8.2 years. The qualifying ACS was a myocardial infarction in 83% and unstable angina in 17%. The study will continue until the positive adjudication of the protocol-specified number of primary CV events. CONCLUSION: ELIXA will be the first trial to report the safety and efficacy of a glucagon-like peptide 1 receptor agonist in people with T2DM and high CV event risk
