Hormonal Implications of SARS-CoV-2: A Review of Endocrine Disruptions.

To improve medical care and rehabilitation algorithms for patients affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is important to evaluate and summarize the available data on the effect of coronavirus infection (COVID-19) on the endocrine system. The purpose of this review was to study the effect of COVID-19 on the endocrine system. The scientific novelty of this study is the evaluation of the effect of coronavirus infection on the endocrine system and the potential effect of hormones on susceptibility to COVID-19.

Conceptual rationale for the use of chemically modified nanocomposites for active influence on atherosclerosis using the greater omentum model of experimental animals.

The use of chemically modified nanocomposites for atherosclerotic plaques can open up new opportunities for studying their effect on changing the structure of the plaque itself. It was shown on the model of the greater omentum of two groups of experimental animals (rats n = 30), which were implanted with Fe@C NPs nanocomposites of 10-30 Nm size into the omentum area. Group 1 (n = 15) consisted of animals that were implanted with chemically modified Fe@C NPs nanocomposites and control group 2 (n = 15) was with non-modified Fe@C NPs nanocomposites.

Effectiveness of Neurofeedback Training for Patients with Personality Disorders: A Systematic Review.

Personality disorders are serious psychiatric conditions, and some studies have examined neurofeedback training as a potential alternative treatment to improve cognitive and clinical symptoms in patients with such disorders. Here, we aimed to provide a first systematic review of such trials and present existing evidence regarding this treatment for individuals with personality disorders. A systematic search of peer-reviewed English journal articles was conducted for this study to identify original studies on fMRI and EEG neurofeedback treatment protocols in patients with personality disorders up to January 2023.

[Sleep disorders in nurses working during the COVID-19 pandemic].

The reorganization of treatment facilities during the COVID-19 pandemic has altered the working conditions of large numbers of the health workers (HW) worldwide. The implementation of professional activities in such realities has led to an increased risk of developing a number of psychological disorders, including insomnia. The percentage of insomnia in HW has increased significantly.

Absorption measurements of cell monolayers relevant to mechanisms of laser phototherapy: reduction or oxidation of cytochrome c oxidase under laser radiation at 632.8 nm.

Objective: The objective of this work was a further investigation of redox mechanisms of laser phototherapy on the cellular level.

Background Data: Cytochrome c oxidase, the terminal enzyme of the mitochondrial respiratory chain, is believed to work as the photoacceptor to modulate cellular metabolism in laser phototherapy.

Materials And Methods: The changes in the absorption spectra of HeLa-cell monolayers before and after irradiation at 632.
