Methodological Approaches to Experimental Evaluation of Neuroprotective Action of Potential Drugs.

The authors propose a novel approach to a comprehensive evaluation of neuroprotective effects using both in vitro and in vivo methods. This approach allows for the initial screening of numerous newly synthesized chemical compounds and substances from plant and animal sources while saving animal life by reducing the number of animals used in research. In vitro techniques, including mitochondrial suspensions and neuronal cell cultures, enable the assessment of neuroprotective activity, which can be challenging in intact organisms.

Unusual BA222-like strains of (Sedoreoviridae: ): molecular and genetic analysis based on all genome segments.

Introduction: Rotavirus infection is the major cause of severe dehydrating diarrhea requiring hospitalization in young children worldwide. Due to their segmented genome, rotaviruses are capable of gene reassortment, which makes the emergence and spread of genetically novel strains possible. The purpose of this study was to search for unusual rotaviruses circulating in Nizhny Novgorod in 2021‒2023 and their molecular genetic characterization based on all genome segments.

Design and implementation of a Type-2 hybrid, prospective randomized trial of opioid agonist therapies integration into primary care clinics in Ukraine.

Introduction: Ukraine has high HIV prevalence, concentrated among people who inject drugs (PWID), mostly of opioids. Maintenance on opioid agonist therapies (OAT) is the most effective evidence-based treatment for opioid use disorder. As PWID experience high morbidity and mortality from preventable and treatable non-communicable diseases, international agencies recommend integrating OAT into primary care centers (PCC).
