[The impact of BMI on the course of the acute SARS-COV-2 infection and the risks that emerge during the first year after the hospital discharge. Subanalysis evidence of the AKTIV and AKTIV 2 registries].

Background: There is enough evidence of the negative impact of excess weight on the formation and progression of res piratory pathology. Given the continuing SARS-CoV-2 pandemic, it is relevant to determine the relationship between body mass index (BMI) and the clinical features of the novel coronavirus infection (NCI).

Aim: To study the effect of BMI on the course of the acute SARS-COV-2 infection and the post-covid period.

[Protocol of intravitreal drug delivery. Consensus of the Expert Counsil of Retina and Optic Nerve Diseases of the All-Russian Public Organasation «Association of Ophthalmologists»].

Intravitreal drug administration is a procedure that has become widespread in modern ophthalmology. However, there is no global consensus on certain aspects of this manipulation, and practitioners feel the need for guidelines. In the Russian Federation, until now, such a document was not available.

[Indocyanine green angiography in the diagnostics of choroidal tumors].

Purpose: To study the use of ultrasound color Doppler imaging and indocyanine green (ICG) angiography for identification of malignant vasculature of choroidal tumors.

Material And Methods: The study included 46 patients (46 eyes) with tumors of the choroid: 19 men and 26 women aged 22 to 89 years, average age 53.2±17.

[New opportunities to improve the treatment effectiveness of patients with stable angina].

Aim To study the antianginal and heart rate slowing effects in patients with stable angina (SA) who failed to achieve the heart rate (HR) goal and were switched from the beta-blocker (BB) metoprolol tartrate to a combination of metoprolol tartrate and ivabradine.Materials and methods The study included 54 patients with SA not higher than functional class (FC) III (35 (64.8 %) men and 19 (35.

High-Frequency ECG for Detection of Myocardial Ischemia Associated with Right Coronary Artery Stenosis in IHD Patients.

Unlabelled: was to study the parameters of high-frequency ECG in leads V, VR, VR, VR, VR as additional diagnostic criteria for detecting the areas of myocardial ischemia associated with stenosis of the right coronary artery (RCA) in IHD patients.

Materials And Methods: The study involved 47 patients who underwent selective coronary angiography (SCA) for detection of IHD. The patients were divided into two groups based on the SCA results: group 1 included 28 patients with hemodynamically significant RCA stenosis; group 2 consisted of 19 patients with hemodynamically non-significant RCA stenosis.

Сomorbidity and polymorbidity of the patient with chronic obstructive pulmonary disease and cardiovascular diseases.

Aim: the study of comorbid status and characteristics of clinical course of ischemic heart disease (IHD) in patients with chronic obstructive pulmonary disease (COPD).

Materials And Methods: We conducted a retrospective analysis of case histories of 958 IHD patients aged 32 to 93 years (mean age of 60.8±10.

Fabrication of artificial opals by electric-field-assisted vertical deposition.

We present a new technique for large-scale fabrication of colloidal crystals with controllable quality and thickness. The method is based on vertical deposition in the presence of a DC electric field normal to the conducting substrate. The crystal structure and quality are quantitatively characterized by microradian X-ray diffraction, scanning electron microscopy, and optical reflectometry.

Double stacking faults in convectively assembled crystals of colloidal spheres.

Using microradian X-ray diffraction, we investigated the crystal structure of convectively assembled colloidal photonic crystals over macroscopic (0.5 mm) distances. Through adaptation of Wilson's theory for X-ray diffraction, we show that certain types of line defects that are often observed in scanning electron microscopy images of the surface of these crystals are actually planar defects at 70.

Microwave irradiation influences on the state of human cell nuclei.

Changes of electrokinetic properties of cell nuclei and the quantity of granules of heterochromatin located near the nuclear envelope in nuclei of human buccal epithelium cells were studied under the influence of electromagnetic fields in vitro. Irradiation of cells was realized by means of a semiconductor generator of millimeter radiation (wavelength 7.1 mm, frequency 42.
