Menstrual function and mental health of medical students during the COVID-19 pandemic: a continuous cross-sectional study

Aim. To assess the impact of new coronavirus infection (NCI) and COVID-19 vaccination on menstrual function in comparison with the frequency of depressive disorders during the COVID-19 pandemic among female students of a medical university. Materials and methods. Data for a continuous transverse (cross-sectional) study were obtained using an online survey. The questions included demographics, characteristics of menstrual function, the history of COVID-19 and vaccinations against it, and the standard CES-D (Center for Epidemiologic Studies Depression Scale) questionnaire. The survey included 1.879 female medical students. The exclusion criteria were age under 18 and over 25 years, hormonal contraceptives, pregnancy, childbirth during the last year, and vaccination after COVID-19. After applying the exclusion criteria, three study groups were formed. Group 1 included female students with a history of NCI (n=140), group 2 included students with no history of NCI, who were initially vaccinated against COVID-19 (n=647), group 3 (control group) included unvaccinated students with no history of NCI (n=55). Results. There were no differences in the prevalence of changes in menstrual function in female students after the NCI (49.3%) and after COVID-19 vaccination (39.6%) compared to the control group (43.6%); p=0.477. The rate of depression in the overall study cohort was 43.3%, without any significant differences between the study groups. Significant predictors of changes in menstrual function during the pandemic were marriage (odds ratio OR 2.33 [1.513.61]), depression (OR 1.72 [1.282.3]), a history of menstrual dysfunction (OR 1.5 [0.121.99]), and later menarche (OR 1.76 [1.023.04]). Multivariate analysis did not show the significance of the history of NCI and vaccination as factors of menstrual dysfunction (OR 1.61 [0.892.90] and OR 0.91 [0.591.41], respectively). Conclusion. During the COVID-19 pandemic, female medical students reported frequent changes in menstrual function and depressive disorders. During the pandemic, the most significant predictors of menstrual disorders in female students were depression, a history of menstrual dysfunction, and marriage. A multicenter prospective study is necessary to clarify the mechanisms of the pandemic's impact on menstrual function

Keratinocytes differentiation and wound healing in rats with streptozotocin – induced diabetes and severe hyperglycemia

BACKGROUND: Diabetes mellitus leads to disruption of the skin repair processes, but the leading mechanisms of this pathology have not yet been identified. In this regard, in our work, we decided to check how hyperglycaemia affects the process of keratinocyte phenotype changes during wound healing. AIMS: To study the effect of hyperglycaemia on wound healing and differentiation of keratinocytes in a rat streptozotocin-induced diabetes model. MATERIALS AND METHODS: Diabetes mellitus was induced in rats by using streptozotocin, 65 mg / kg, intraperitoneally, once. The wound was applied in the supra-scapular region on the 42nd day, after which (after 8, 16, and 24 days) the repair process was evaluated using histological methods. Immunohistochemistry was used to evaluate the expression of cytokeratin-10 and cytokeratin-17. RESULTS: In rats with diabetes mellitus, wound healing slowed down in the later stages, compared with the control group. In general, wound healing was accompanied by an increase in the expression of cytokeratin-10 in its region compared with intact skin, and contractile keratinocytes activation was disrupted in diabetic rat wounds. CONCLUSIONS: Hyperglycaemia slightly slows wound healing in rats and impairs contractile keratinocytes activation

Dynamics of heart rate variability in rats with streptozotocin-induced diabetes

Background: Diabetes mellitus (DM) has a negative impact on all organs. This is due to insufficiency of blood supply and the disruption of the trophic function of the nervous system. One of the most serious complication of DM is diabetic foot caused be vascular and neurological reasons. Correction of vascular disorders is effectively treated by modern therapeutic approaches, but the damage of nervous system has been studied insufficiently. Aims: To investigate the dynamics of damage to the vegetative nervous system on the laboratory model of DM. Materials and methods: DM in rats was induced by injection of streptozotocin at a dose of 65 mg/kg in citrate buffer (DM group). The control group of rats received a citrate buffer equivalent (CB group). Rats with DM were given a maintenance therapy with insulin in a dose of 2 units/kg/day. On 42 days of experience, a round wound with a diameter of 2 cm on the back of the animals was observed. Before the DM simulation, then on the 42, 50, 58 and 66 days of its development, an electrocardiogram (ECG) was recorded in the rats at a frequency of 2 kHz digitising in a state of calm wakefulness and after cold exposure. For 5 minutes ECG fragments, heart rate and heart rate variability (HRV) in the temporal domain were calculated, characterising: 1) the total heart rate variability (tHRV) according to SDRR, SDHR, KVRR and KVHR; 2) the effect of the parasympathetic department of the autonomic nervous system (aANS) for RMSSD and pNN3; 3) the contribution of the sympathetic department of the ANS (sANS) by SDAvgRR, SDAvgHR. The spectral parameters were estimated in the frequency domain: the total power of the spectrum is TR (range: 0–2.5 Hz), the powers in the low and high frequency ranges are LF (range: 0.2–0.8 Hz) and HF (range: 0.8–2.5 Hz) LF/HF. Weekly, the tail withdrawal time was measured in a temperature pain test (55°C). Results: During the development of diabetes, the level of glucose in the blood increased 4–7 times compared with the normal level. The reaction time of the pain test in rats with DM increased by 20%–30% at the end of the experiment. At 42 days, the development of bradycardia (267 beats/min) was observed in rats with DM. The indicators of tHRV decreased by a factor of 2 due to a decrease in the contribution of sANS. The reaction to CP in the SD group differs from the norm by the severity of the individual components of the HRV structure, which indicates functional denervation of the heart and the development of diabetic neuropathy. Conclusions: As the diabetes progressed, signs of neuropathy were observed. The overall HRV parameters decreased, the ratio of the contributions of sANS and pANS to the regulation of heart rate changed, and the temperature sensitivity decreased

Determinants of GBP Recruitment to Toxoplasma gondii Vacuoles and the Parasitic Factors That Control It

IFN-γ is a major cytokine that mediates resistance against the intracellular parasite Toxoplasma gondii. The p65 guanylate-binding proteins (GBPs) are strongly induced by IFN-γ. We studied the behavior of murine GBP1 (mGBP1) upon infection with T. gondii in vitro and confirmed that IFN-γ-dependent re-localization of mGBP1 to the parasitophorous vacuole (PV) correlates with the virulence type of the parasite. We identified three parasitic factors, ROP16, ROP18, and GRA15 that determine strain-specific accumulation of mGBP1 on the PV. These highly polymorphic proteins are held responsible for a large part of the strain-specific differences in virulence. Therefore, our data suggest that virulence of T. gondii in animals may rely in part on recognition by GBPs. However, phagosomes or vacuoles containing Trypanosoma cruzi did not recruit mGBP1. Co-immunoprecipitation revealed mGBP2, mGBP4, and mGBP5 as binding partners of mGBP1. Indeed, mGBP2 and mGBP5 co-localize with mGBP1 in T. gondii-infected cells. T. gondii thus elicits a cell-autonomous immune response in mice with GBPs involved. Three parasitic virulence factors and unknown IFN-γ-dependent host factors regulate this complex process. Depending on the virulence of the strains involved, numerous GBPs are brought to the PV as part of a large, multimeric structure to combat T. gondii.National Institutes of Health (U.S.)Massachusetts Life Sciences Center (New Investigator Award)National Institute of General Medical Sciences (U.S.) (Pre-Doctoral Grant in the Biological Sciences (5-T32-GM007287-33))Studienstiftung des deutschen VolkesCancer Research Institute (New York, N.Y.)Cleo and Paul Schimmel FoundationBayer HealthcareHuman Frontier Science Program (Strasbourg, France

Formation of properties of meat-containing canned food with the use of rabbit meat for children’s and dietary food

The modern level of knowledge about food products allows them to be developed with specified properties that correspond to a specific purpose. The creation of such products is always a search for a reasonable compromise between the numerous requirements for food products. The article reflects the results of a scientific study devoted to the development of a recipe for canned meat for baby food with a different percentage of rabbit meat and vegetables. Comprehensive studies of the consumer properties of canned food obtained according to one of the author’s recipes were carried out. The obtained data and their analysis made it possible to choose the most optimal option for canned food, which will be in demand and competitive in relation to other types of products in the assortment group

Determination of the development level of information and telecommunication networks within the regions of Siberian Federal District

According to the scientific papers of the Russian scientists, the parameters for assessing the quality of economic space are population density, spatial connectivity and location of production. The parameter of the spatial connectivity is considered. In most of the Russian scientific papers, the term “the spatial connectivity” is determined by the level of transport networks development. In most Russian scientific papers when forming models for assessing the spatial connectivity of regions, the issue of territorial connectivity by information and telecommunication networks is not investigated. The papers analyses the main characteristics of the concept of regional space connectivity and its properties. An econometric analysis of statistical data on indicators characterizing information and telecommunication networks for each of the regions of the Siberian Federal District has been carried out. The mathematical model and an algorithm for automating the procedure for calculating statistical indicators in the Python language in the Spyder programming environment were proposed for calculating the indicators. The most and least developed regions within developing the information and telecommunication networks have been identified. The resulting mechanism for determining the level of development of information and telecommunication networks will be useful for monitoring the territory and drawing up a passport of an each region

However, the range of butter sold in the retail chain is represented by such names as Traditional, Amateur, Peasant, Chocolate. In this connection, there is a need to create new types of butter with high consumer properties. The technology and recipes of dessert butter with black currant have been developed. The analysis of organoleptic and physico-chemical indicators of the quality of the developed butter with black currant is carried out. The optimal amount of black currant is determined when creating dessert butter

A Bioinformatic Pipeline for Monitoring of the Mutational Stability of Viral Drug Targets with Deep-Sequencing Technology

The efficient development of antiviral drugs, including efficient antiviral small interfering RNAs (siRNAs), requires continuous monitoring of the strict correspondence between a drug and the related highly variable viral DNA/RNA target(s). Deep sequencing is able to provide an assessment of both the general target conservation and the frequency of particular mutations in the different target sites. The aim of this study was to develop a reliable bioinformatic pipeline for the analysis of millions of short, deep sequencing reads corresponding to selected highly variable viral sequences that are drug target(s). The suggested bioinformatic pipeline combines the available programs and the ad hoc scripts based on an original algorithm of the search for the conserved targets in the deep sequencing data. We also present the statistical criteria for the threshold of reliable mutation detection and for the assessment of variations between corresponding data sets. These criteria are robust against the possible sequencing errors in the reads. As an example, the bioinformatic pipeline is applied to the study of the conservation of RNA interference (RNAi) targets in human immunodeficiency virus 1 (HIV-1) subtype A. The developed pipeline is freely available to download at the website http://virmut.eimb.ru/. Brief comments and comparisons between VirMut and other pipelines are also presented

Six Highly Conserved Targets of RNAi Revealed in HIV-1-Infected Patients from Russia Are Also Present in Many HIV-1 Strains Worldwide

RNAi has been suggested for use in gene therapy of HIV/AIDS, but the main problem is that HIV-1 is highly variable and could escape attack from the small interfering RNAs (siRNAs) due to even single nucleotide substitutions in the potential targets. To exhaustively check the variability in selected RNA targets of HIV-1, we used ultra-deep sequencing of six regions of HIV-1 from the plasma of two independent cohorts of patients from Russia. Six RNAi targets were found that are invariable in 82%–97% of viruses in both cohorts and are located inside the domains specifying reverse transcriptase (RT), integrase, vpu, gp120, and p17. The analysis of mutation frequencies and their characteristics inside the targets suggests a likely role for APOBEC3G (apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3G, A3G) in G-to-A mutations and a predominant effect of RT biases in the detected variability of the virus. The lowest frequency of mutations was detected in the central part of all six targets. We also discovered that the identical RNAi targets are present in many HIV-1 strains from many countries and from all continents. The data are important for both the understanding of the patterns of HIV-1 mutability and properties of RT and for the development of gene therapy approaches using RNAi for the treatment of HIV/AIDS.
