The mortality burden related to COVID-19 in 2020 and 2021 - years of life lost and excess mortality in 13 countries and sub-national regions in Southern and Eastern Europe, and Central Asia.

Introduction: Between 2021 and 2023, a project was funded in order to explore the mortality burden (YLL-Years of Life Lost, excess mortality) of COVID-19 in Southern and Eastern Europe, and Central Asia.

Methods: For each national or sub-national region, data on COVID-19 deaths and population data were collected for the period March 2020 to December 2021. Unstandardized and age-standardised YLL rates were calculated according to standard burden of disease methodology.

IMPROVEMENT OF THE METHODOLOGY OF BIOMATERIAL COLLECTION FOR THE DIAGNOSIS OF THE ORAL CAVITY MUCOSA DISEASES.

Aim - to improve the methodology for collecting material from lesions of the oral mucosa for exfoliative cytological examination. A group of patients diagnosed with B37.0 Candida stomatitis was examined.

MODERN TRENDS OF CHANGES IN THE MICROBIOTA OF UROGENITAL SYSTEM IN PATIENTS WITH UROLITHIASIS.

Objective: Aim: Analysis of trends in the microbial communities of the genitourinary system in patients with urolithiasis.

Patients And Methods: Materials and Methods: 165 urine samples from patients with urolithiasis was examined. The quantitative isolation of microflora was carried out using the bacteriological method.

Dynamic changes in O-GlcNAcylation regulate osteoclast differentiation and bone loss via nucleoporin 153.

Bone mass is maintained by the balance between osteoclast-induced bone resorption and osteoblast-triggered bone formation. In inflammatory arthritis such as rheumatoid arthritis (RA), however, increased osteoclast differentiation and activity skew this balance resulting in progressive bone loss. O-GlcNAcylation is a posttranslational modification with attachment of a single O-linked β-D-N-acetylglucosamine (O-GlcNAc) residue to serine or threonine residues of target proteins.
