Elucidation of Potential Genotoxicity of MXenes Using a DNA Comet Assay.

MXenes are among the most diverse and prominent 2D materials. They are being explored in almost every field of science and technology, including biomedicine. In particular, they are being investigated for photothermal therapy, drug delivery, medical imaging, biosensing, tissue engineering, blood dialysis, and antibacterial coatings.

MXene-Assisted Ablation of Cells with a Pulsed Near-Infrared Laser.

Innovative therapies are urgently needed to combat cancer. Thermal ablation of tumor cells is a promising minimally invasive treatment option. Infrared light can penetrate human tissues and reach superficial malignancies.

[Sonographic parameters of spleen in children depending on the level of anthropogenic pollution of areas of residence].

Sonographic parameters of spleen in children living in the Orenburg region taking into account the level and character of anthropogenous pollution of territory of residing are studied. The analysis of indicators of pollution of factors of inhabitancy (atmospheric air, potable water soil) is carried out. One-stage population research of 7000 children aged from 1 to 18 years living in urbanized and rural territories is conducted.

[Children's health status in relation to the level and nature of anthropogenic pollution].

The frequency of health groups 1 and 2 was studied in children living in the areas of the Orenburg Region, by taking into account the level and nature of their anthropogenic pollution. The pollution indicators of environmental objects (ambient air, drinking water, soil) were analyzed. A cross-sectional population-based study was conducted in 7000 children aged 1 month to 18 years, who lived in the urban and rural areas.

[Prevalence of alcohol use among school children and vocational school students in Murmansk].

Anonymous questionnaires were distributed among 1564 schoolchildren in Murmansk for the study carried out in accordance with the method recommended by Center for Monitoring Harmful Habits among Children and Adolescents at Ministry of Health of Russia. The data indicate alcoholization of adolescents in the city. The results were used for planning and implementation of preventive measures within the framework of the SOS! complex regional program.

[Change in prostanoid metabolism in cystic kidney lesion].

A wide range of renal prostaglandins in cysts has been studied as compared with their content in the daily urine, activity of plasma renin, level of adrenocorticotropic hormone (ACTH) in the tissues, methionine enkephalin and aldosterone. High activity of renin, met-enkephalin and ACTH was observed in the patients with one cyst. Under renal polycystosis the activity of plasma renin is higher and the amount of ACTH positively decreases.
