The clinical and immunological spectrum of acute post-active COVID-19 syndrome overlaps with criteria used to characterize autoimmune diseases such as rheumatoid arthritis (RA) systemic lupus erythematosus (SLE). Indeed, following SARS-Cov2 infection, the innate immune response is altered an initial delayed production interferon type I (IFN-I), while NF-kappa B inflammasome pathways are activated. In lung digestive tissues, alternative extrafollicular against takes place with, consequently,...

To investigate diversity of mitochondrial gene pool Tatars inhabiting the territory middle Volga River basin, 197 individuals from two populations representing Kazan and Mishars were subjected for analysis DNA (mtDNA) control region variation. In addition, 73 genomes Mishar population sequenced completely. It was found that consists parts, but western Eurasian component prevails considerably (84% on average) over eastern Asian one (16%). Eastern mtDNAs detected in belonged to a heterogeneous...

Exercise-induced oxidative stress is a state that primarily occurs in athletes involved high-intensity sports when pro-oxidants overwhelm the antioxidant defense system to oxidize proteins, lipids, and nucleic acids. During exercise, linked muscle metabolism damage, because exercise increases free radical production. The T allele of Ala16Val (rs4880 C/T) polymorphism mitochondrial superoxide dismutase 2 (SOD2) gene has been reported reduce SOD2 efficiency against stress. In present study we...

The aim of this research was to assess lipid peroxidation (LPO) and antioxidative defense (AOD) changes in adolescent boys with obesity using the integral index. Materials Methods:We examined 19 first degree (the study group).The control group included 23 healthy boys.The collection anamnestic data, physical examination, anthropometric data analysis (body weight (BW), height, waist circumference (WC), hip (HC), body mass index (BMI)).Laboratory an assessment blood levels total cholesterol,...

Abstract A major challenge presently is not only to identify the genetic polymorphisms increasing risk diseases, but also find out factors and mechanisms, which can counteract a genotype by developing resilient phenotype. The objective of this study was examine acquired innate vagal mechanisms that protect against physical challenges haemorrhages in 19 athletes 61 non-athletes. These include examining change heart rate variability (HF-HRV; an indicator vagus activity) response orthostatic...

Oral microbiome changes take place at the initiation of rheumatoid arthritis (RA); however, questions remain regarding oral pre-RA stages in individuals with clinically suspect arthralgia (CSA). Two cross-sectional cohorts were selected including 84 Tatarstan women (15 early-RA as compared to CSA ranging from = 0 [n 22], 1 19], 2 11], and ≥ 3 17]) 42 established RA (median: 5 years diagnosis [IQ: 2-11]). Amplicon sequence variants (ASVs) obtained samples (16S rRNA) analyzed for alpha beta...

Abstract Mutations in the MYH9 gene result macrothrombocytopenia often associated with hemorrhages. Here, we studied function and structure of platelets three family members a heterozygous mutation R1933X gene, characteristic closely related disorders known as May-Hegglin anomaly Sebastian syndrome. The examination included complete blood count, smear microscopy, platelet flow cytometry (expression P-selectin active integrin αIIbβ3 before after activation), kinetics platelet-driven...

A familial history of rheumatoid arthritis (RA) predisposes an individual to develop RA. This study aimed at investigating factors associated with this conversion from the Tatarstan cohort.A total 144 individuals, referred as pre-RA and risk for RA, were selected 2 years (range: 2-21 years) before RA compared non-converted 328 first-degree relatives (FDR) assessed after ≥2 follow-up, 355 healthy controls also (HC). Preclinical parameters socio-demographic/individual/HLA genetic analyzed when...

Genetic predisposition alongside with environmental factors play a major role in the pathogenesis of coronary heart disease, causing deregulation various biochemical processes leading to disease onset. Antioxidant system deregulation, marked mainly by lipid peroxidation products and number enzymes, is known be one risk for disease. A genetic defect might lead change enzyme activity inhibition antioxidant protection. However, pathogenic mechanisms different clinical courses are not studied...
