ASSESSMENT OF CHANGES IN HEART RATE VARIABILITY INDICES OF STUDENTS AFTER COVID-19 LOCKDOWN: A COHORT STUDY.

Introduction: The objective of this study was to investigate the heart rate variability indicators of students who had contracted COVID-19 after performing physical activity. The aim was to uncover the potential cardiac complications and dysregulations of the autonomic nervous system.

Material And Method: We explored about 11 heart rate variability indicators and their changes immediately after a 5-minute physical activity performed by using Proteus pes 3320 bicycle odometer.

Structural and biochemical characterisation of the N-carbamoyl-β-alanine amidohydrolase from Rhizobium radiobacter MDC 8606.

N-carbamoyl-β-alanine amidohydrolase (CβAA) constitutes one of the most important groups of industrially relevant enzymes used in the production of optically pure amino acids and derivatives. In this study, a CβAA-encoding gene from Rhizobium radiobacter strain MDC 8606 was cloned and overexpressed in Escherichia coli. The purified recombinant enzyme (RrCβAA) showed a specific activity of 14 U·mg using N-carbamoyl-β-alanine as a substrate with an optimum activity at 55 °C and pH 8.

Laser Therapy Changes the Expression of Matrix Metalloproteinases in Bleomycin-Induced Skin Fibrosis.

Matrix metalloproteinases (MMPs) are often considered biomarkers of skin fibrosis. At the early stages of the pathological process, an elevation of their enzymatic activity causes significant changes in the composition of the extracellular matrix. MMPs secreted by immune cells facilitate their migration to the site of damage.

Primary healthcare providers challenged during the COVID-19 pandemic: a qualitative study.

Background: Primary healthcare (PHC) providers are widely acknowledged for putting the most efficient and long-lasting efforts for addressing community health issues and promoting health equity. This study aimed to explore PHC providers' experiences with coronavirus pandemic preparedness and response in Armenia.

Methods: We applied a qualitative study design using semi-structured in-depth interviews and structured observation checklists.

The epidemiological status of African swine fever in domestic swine herds in the Tavush Province region, Armenia.

KEEN The factors associated with the spread and persistence of African swine fever (ASF) in the Caucasus region remain to be fully identified. It is assumed that large naive populations of domestic free-ranging and wild pigs are critical to disease transmission and maintenance. Nonetheless, 11 years since its epidemic introduction into the region in 2007, ASF virus (ASFV) is still circulating, suggesting that an endemic cycle has been established based on contact between free-ranging domestic pigs and wild pigs, and that native Ornithodoros ticks probably serve as reservoirs for the virus.
