The Role of Genetic Factors in the Development of Acute Respiratory Viral Infection COVID-19: Predicting Severe Course and Outcomes.

The aim of this study was to identify single nucleotide variants in genes associated with susceptibility to or severe outcomes of COVID-19. A total of 319 genomic DNA samples from patients with varying degrees of disease severity and 78 control DNA samples from people who had regular or prolonged contact with patients with COVID-19 but did not have clinical manifestations and/or antibodies to SARS-CoV-2. Seven SNPs were identified that were statistically associated with disease risk or severe course, rs1799864 in the gene (OR = 2.

Optically transparent electrodes to study living cells: A mini review.

The use of electrochemical methods to study living systems, including cells, has been of interest to researchers for a long time. Thus, controlling the polarization of the electrode contacting living cells, one can influence, for example, their proliferation or the synthesis of specific proteins. Moreover, the electrochemical approach formed the basis of the biocompatibility improvement of the materials contacting with body tissues that use in carbon hemosorbents and implants development.

Impact of pathogen reduction methods on immunological properties of the COVID-19 convalescent plasma.

Background And Objectives: COVID-19 convalescent plasma is an experimental treatment against SARS-CoV-2. The aim of this study is to assess the impact of different pathogen reduction methods on the levels and virus neutralizing activity of the specific antibodies against SARS-CoV2 in convalescent plasma.

Materials And Methods: A total of 140 plasma doses collected by plasmapheresis from COVID-19 convalescent donors were subjected to pathogen reduction by three methods: methylene blue (M)/visible light, riboflavin (R)/UVB and amotosalen (A)/UVA.

Diagnosis and treatment of persons with acute thallium poisoning.

Objective: This study aimed to describe organs and systems damages in persons after mass poisoning with thallium and show the results of treatment.

Methods: Forty-four persons (12 males and 32 females) with acute oral thallium poisoning were tested for thallium levels in blood and urine and examined by a toxicologist and a neurologist, and in some -cases, by a gynecologist, an ophthalmologist, and a psychiatrist. Persons were divided into the following three groups depending on the severity of the poisoning: I: This group consisted of 9 persons (blood thallium level 8.

Thermovaccination - thermoheliox as a stimulator of the immune response. Kinetics of the synthesis of antibodies and C-reactive protein in coronavirus infection.

Clinical trials of thermoheliox application (inhalation with a high-temperature mixture of oxygen and helium, 90 °C) in the treatment of the acute phase of coronavirus infection were conducted. Dynamics of disease development in infected patients (PCR test for the virus) and, dynamics of changes in blood concentration of C-reactive protein, immunoglobulin M, specific immunoglobulin G were studied. High efficiency of thermoheliox in releasing the organism from the virus and stimulating the immune response (thermovaccination effect) was shown.

Clinical and pathophysiologic aspects of ECMO-associated hemorrhagic complications.

Extracorporeal membrane oxygenation (ECMO) is increasingly used to treat severe cases of acute respiratory or cardiac failure. Hemorrhagic complications represent one of the most common complications during ECMO, and can be life threatening. The purpose of this study was to elucidate pathophysiological mechanisms of ECMO-associated hemorrhagic complications and their impact on standard and viscoelastic coagulation tests.
