Hepatitis E Virus Infection in Voluntary Blood Donors in the Russian Federation.

Transfusion-transmitted hepatitis E virus (HEV) infection is an increasing concern in many countries. We investigated the detection rate of HEV viremia in blood donors in Russia. A total of 20,405 regular repetitive voluntary non-renumerated blood donors from two regions (Moscow and Belgorod) were screened for HEV RNA using the cobas HEV test in mini-pools of six plasma samples.

Impact of Environmental Radiation on the Incidence of Cancer and Birth Defects in Regions with High Natural Radioactivity.

Four regions of high natural radioactivity were selected to assess radionuclide levels in rocks and soils, ambient radiation doses, radon exhalation from the ground, and radon concentrations in the air. The regions have different geochemical characteristics and radioactivity levels, which modulate the radiation exposure of local populations. Combining radiometric data with data from regional health statistics on non-infectious diseases, a statistically significant positive correlation was found between radiation exposure and the incidence of cancer and birth defects.

Preventive behaviours during the pandemic: The role of collective rituals, emotional synchrony, social norms and moral obligation.

The present research focuses on the role of collective, social influence and intraindividual processes in shaping preventive behaviours during the COVID-19 pandemic. In two correlational studies conducted in Spain, we explored the impact of participation in the ritual of collective applause (carried out daily for over 70 days during the lockdown) and perceived social norms in fostering behavioural adherence to public health measures, as well as the mediating role of perceived emotional synchrony and a sense of moral obligation. The first study (general population, N = 528) was conducted in June 2020, just after the end of the lockdown, and the second study (students, N = 292) was carried out eight months later.

Influences of geological factors on the distribution of uranium in drinking water limescale in the junction zone of the East European Platform and the Southern Urals.

An assessment of uranium contents and distribution in drinking water limescale has been conducted in the Republic of Bashkortostan (RB), Russia. A total of 515 limescale samples from 262 settlements of the RB were analyzed. The spread of U concentration values in limescale samples ranged from 0.

[The risk groups of infection with hepatitis С virus in conditionally healthy population of the Belgorod oblast].

The purpose of study was to establish risk group on hepatitis C in conditionally healthy population of the Belgorod oblast. Total 2025 conditionally healthy inhabitants aged between 1 and 99 were surveyed and serum samples from them were tested. There were eight age groups: 1-14 years (12.

[Features of psycho-emotional state of patients with central serous chorioretinopathy].

Aim: to investigate peculiarities of psycho-emotional reactions in patients with central serous chorioretinopathy (CSCR).

Material And Methods: The study involved 35 patients with CSCR (mean age of 47.7±8.

[Possibilities of submicron objects study in blood of workers].

The article contains results of studies characterizing nanoparticles in blood and serum of exposed workers engaged into titanium and magnesium production and workers outside coverage of occupational factors. Comparative study of the workers' serum included dynamic light dispersion, scanning electronic microscopy, transmission electronic microscopy. Measuring despersion characteristic of blood serumin the workers exposed to nanomaterial revealed increased percentage of particles with hydrodynamic diameter within 60-100 nm and over 100 nm.

[Results obtained in evaluation of parameters characterizing air-borne nanoparticles at a titanium-production facility].

To reveal, identify and evaluate nano-particles content, the authors performed screening studies of nano-particles in the air of workplace contaminated with aerosol coming from high-temperature titanium smelting. The studies involved diffuse spectrometry, scanning electronic microscopy, energy dispersion analysis, mass spectrometry with inductively coupled plasma. Objects identified are nano-particles with average aerodynamic diameter ranging 35.
