Modern experimental methods for assessing the effectiveness of tissue-engineered products for hyaline cartilage regeneration.

Hyaline cartilage (HC) is a specialized connective tissue that covers the surfaces of major joints and is characterized by its limited regenerative capacity. Modern therapeutic approaches to HC restoration often do not provide complete regeneration of damaged tissue. Developed tissue engineering methods show promise as effective approaches for restoring various types of HC damage.

Assessment of mutagenic effects: Combined impact of nitrogen-fixing compounds and phenol on plant and animal organisms.

Introduction: Rapid industrialisation, urbanisation, and increased use of agricultural chemicals have significantly contributed to environmental pollution, particularly affecting air, water, and soil quality. These pollutants, including nitrogen-containing compounds and phenol, pose mutagenic risks, potentially leading to genetic alterations and health issues in exposed populations. This study aims to evaluate the mutagenic potential of sodium nitrate, sodium nitrite, phenol, and their combinations on plant and animal cells.

Green Chemistry and Microbial Defense: Evaluating Glycyrrhiza glabra Leaf Extracts, SEM Catalysts, and Antibacterial Agents.

The green catalytic synthesis of metallic nanoparticles from medicinal plants offers a sustainable and eco-friendly approach toward nanoparticle production. This study also explored the antimicrobial potential of nanoparticles, representing promising implications for their application in combating microbial pathogens. We describe the eco-friendly synthesis of silver nanoparticles (Ag NPs) utilizing leaf extract from Glycyrrhiza glabra .

Clinical Features of COVID-19 in Uzbekistan.

Background: As of April 30, 2020, a total of 2,039 cases of the novel coronavirus disease 2019 (COVID-19) were confirmed in the Republic of Uzbekistan after the first detection on March 15. Reports on symptoms of COVID-19 are non-specific and known to vary from asymptomatic, mild to severe, or fatal. This study aimed to analyze the symptomatic and clinical characteristics of study participants based on the medical records of participants hospitalized with COVID-19 in Uzbekistan.

Helicobacter pylori infection and cytokine gene polymorphisms in Uzbeks.

Recent studies have reported that Helicobacter pylori (H. pylori) persistent infection and gastric atrophy development were associated with genetic polymorphisms of cytokines. This study aimed to determine possible associations of host genotypes with the seropositivity of anti-H.
