According to the World Health Organization, ischemic stroke is the second leading cause of death in the world. Frequently, it is caused by brachiocephalic artery (BCA) atherosclerosis. Timely detection of atherosclerosis and its unstable course can allow for a timely response to potentially dangerous changes and reduce the risk of vascular complications.

Vaccination is the most cost-effective method of preventing COVID-19; however, data on its effect on patients with multimorbidity is limited. The aim was to evaluate the effect of vaccination against new coronavirus infection (NCI) in patients with multimorbid pathology in hospital treatment on the outcome of COVID-19 disease. An analysis was carried out of 1832 records of patients in one of the COVID-19 hospitals in Moscow for 2020-2022.

During the COVID-19 pandemic, the problem of the population's adherence to vaccination has become significantly aggravated around the world. This study is aimed at evaluating healthcare workers' (HCWs) acceptance of COVID-19 vaccination in Russia. A cross-sectional multicenter study was carried out by interviewing HCWs in Russia using an electronic questionnaire and snowball sampling.

Unlabelled: The aim of the present study is to determine the prognostic value of GFR reduction according to the CKD-EPI formula, taking into account blood creatinine and a formula that simultaneously takes into account creatinine and cystatin C in patients who were hospitalized for the first time due to decompensation of chronic heart failure with a preserved left ventricular ejection fraction (HFSA) observation within 24 months.

Materials And Methods: The study included 117 patients (women - 65.8%, mean age 71.

Until today, there are no universally accepted methods for detection of unstable atherosclerotic plaques, even though many recent studies were devoted to this issue. In this article we present modern possibilities of computed tomography in visualization of atherosclerotic coronary lesion, including the detection of unstable lesions, whot in turn, can help in diagnosing subclinical exacerbation of ischemic heart disease and in the stratification of risks of acute coronary events.

Nowadays an invasive evaluation of fractional flow reserve (FFR) is one of the main methods used for detecting lesions that cause ischemia. Invasively obtained FFR <0.75 has the specificity of 100 %, and FFR >0.

Small antibody mimetics, or alternative binding proteins (ABPs), extend and complement antibody functionality with numerous applications in research, diagnostics and therapeutics. Given the superiority of ABPs, the last two decades have witnessed development of dozens of alternative protein scaffolds (APSs) for the design of ABPs. Proteins from extremophiles with their high structural stability are especially favorable for APS design.

Due to their remarkably high structural stability, proteins from extremophiles are particularly useful in numerous biological applications. Their utility as alternative protein scaffolds could be especially valuable in small antibody mimetic engineering. These artificial binding proteins occupy a specific niche between antibodies and low molecular weight substances, paving the way for development of innovative approaches in therapeutics, diagnostics, and reagent use.

A method for generation of highly specific miniantibodies within the phage particle has been developed, and used to produce antibodies against Staphylococcus enterotoxin type C1. Under successive panning of the non-immune phage miniantibody (scFv) library with enterotoxins SE (types A, B, C1, D, E, G, and I) adsorbed on the plate surface, we generated 11 individual phage clones to Staphylococcus enterotoxin type C1. Five of them interacted specifically only with SEC1 and had no cross-reactions with the other enterotoxins.

The influence of alterations in the format of antibodies on their specificity has been examined. To analyze the role of Ig constant regions in recognizing antigens, a comparison was made of the specificities of full-scale murine monoclonal antibodies and scFv single-chain miniantibodies obtained from the latter with regard to a group of closely related protein antigens - Staphylococcus enterotoxins. It was found that in the scFv format the specificity and affinity of miniantibodies diminished as compared to the full-scale ones.
