[VATS resection of basal pyramid segments in sequestration of the left lower lobe].

Lung sequestration is a congenital malformation represented by a non-functioning pulmonary parenchyma supplied via an aberrant artery of systemic circulation. This malformation makes up 1-6% of all congenital lung abnormalities. In 1946, Pryce M.

Phase Equilibria in The MnGa2T?4-MnIn2T?4 System, Crystal Structure and Physical Properties of MnGaInT?4.

The phase equilibria in the MnGa2T?4-MnIn2T?4 system were experimentally investigated by means of differential thermal analysis and powder X-ray diffraction technique. It was found that this system is quasi-binary and characterized by dystectic and eutectic equilibria and the formation of a wide area of solid solutions based on the starting compounds. The crystal structures of the MnGaInTe4 and MnIn2T?4 were refined by the Rietveld method using powder X-ray diffraction data.

Beta-blockers: propranolol, metoprolol, atenolol, pindolol, alprenolol and timolol, manifest atherogenicity on in vitro, ex vivo and in vivo models. Elimination of propranolol atherogenic effects by papaverine.

The addition of the beta-blockers propranolol, metoprolol, atenolol, pindolol, alprenolol and timolol to a culture of peritoneal macrophages or smooth muscle cells induced an increase in the intracellular cholesterol content. Blood serum obtained from a rabbit after a peroral administration of beta-blockers also induced cholesterol accumulation. This property of drug or blood serum obtained after peroral administration is conventionally referred to as atherogenic potential or atherogenicity.

[Echocardiographic assessment of cardiac pump function using afterloading characteristics].

Seventy five patients and twenty healthy individuals were investigated by using cardiac ultrasound technique, followed by mathematical simulation of changes in left ventricular pressure during contraction. The findings show that the afterload characteristics based on a wealth of evidence for cardiac and left ventricular performance, unlike the conventional central hemodynamic parameters and cardiac phasic indices, enable the occult circulatory disorders to be revealed and the cardiac compliance with the arterial system to be assessed.

[The structure of the endothelialized and nonendothelialized areas of myointimal thickening of the rabbit aorta].

De-endothelialization of the abdominal aorta of the rabbit was performed with a balloon catheter. As a result, a partially endothelialized myointimal thickening was formed consisting of smooth myocytes and macrophages. As compared with the zone devoid of the endothelium the endothelialized zone was characterized by less thickness and by the presence of an additional elastic membrane.
