New Technological Approaches to the Organization of the Work of Medical Personnel Performing Auscultation of Patients with COVID-19.

Due to the COVID-19 epidemic, the challenge of introducing methods for investigating patients reducing or eliminating the probability of infection of medical staff is currently relevant. This article provides an analytical review of new technological approaches to organizing the work of medical personnel in carrying out auscultation of patients with COVID-19. The development and approval of such technologies is shown to have started around the world.

The collagen cross-linking enzyme lysyl oxidase is associated with the healing of human atherosclerotic lesions.

Background: Acute clinical complications of atherosclerosis such as myocardial infarction (MI) and ischaemic stroke are usually caused by thrombus formation on the ruptured plaque surface. Collagen, the main structural protein of the fibrous cap, provides mechanical strength to the atherosclerotic plaque. The integrity of the fibrous cap depends on collagen fibre cross-linking, a process controlled by the enzyme lysyl oxidase (LOX).

Effect of pancragen on blood glucose level, capillary permeability and adhesion in rats with experimental diabetes mellitus.

The effects of tetrapeptide pancragen (Lys-Glu-Asp-Trp-NH2) on blood glucose level and permeability and adhesion of mesenteric capillaries were studied in Wistar rats with experimental streptozotocin-induced diabetes mellitus. Oral pancragen produced a pronounced hypoglycemic effect during treatment. Intramuscular pancragen normalized the adhesion of mesenteric capillary endothelium, but did not modify capillary permeability.

Effect of peptide Vilon on the content of transforming growth factor-beta and permeability of microvessels during experimental chronic renal failure.

We studied the effect of Vilon in rats 2, 4, and 6 months after the onset of chronic renal failure. Subcutaneous injection of Vilon significantly decreased serum concentration of transforming growth factor-beta(1) and permeability of mesenteric microvessels in rats 2 months after the onset of chronic renal failure. Our results indicate that the preparation produces a potent homeostatic effect in the early period of chronic renal failure.
