[Influence of chronic obstructive pulmonary disease on hospital outcomes of percutaneous coronary interventions in patients with acute coronary syndrome].

Aim: To evaluate the impact of chronic obstructive pulmonary disease (COPD) on hospital outcomes of percutaneous coronary interventions (PCI) in patients with acute coronary syndrome (ACS).

Materials And Methods: A cohort prospective study of the COPD effect on mortality and coronary microvascular obstruction (CMVO, no-reflow) development after PCI in ACS was carried out. 626 patients admitted in 2019-2020 were included, 418 (67%) - men, 208 (33%) - women.

Tetracyclines induce changes in accessibility of ribosomal proteins to proteases.

Limited proteolysis was used to test the interaction of tetracyclines and some of their derivatives with ribosomes. Proteolysis of the free ribosomes was compared with that of the ligand-bound ribosomes. The interaction of different tetracyclines with ribosomes depends on their chemical structure and produces both a protective effect and an increased susceptibility to proteases of some ribosomal proteins in the 30S and 50S subparticles.

Growth, activity of phytohormones and inhibitors, and photosynthesis of dwarf pea mutants under different conditions of illumination.

A clear correlation was found between the growth of mutant forms of pea plants and the light intensity: With an increase in the latter the growth of the plants was inhibited and the rate of photosynthesis increased. The inhibitory action of light on stem growth affected not only tall pea plants, but also dwarf forms. A definite link was observed between the genetic apparatus and the balance of endogenous phytohormones and inhibitors.
