Mechanisms of low-temperature vapor-gas streams formation from sulfide mine waste.

This paper presents experimental data that revealed the potential for chemical element transport by low-temperature vapor-gas streams. The study was conducted on sulfide waste heap sites located in the Kemerovo region, Russia. Condensates of vapor-gas streams were collected and analyzed in the air above the waste heaps and during laboratory experiments using samplers specially designed for this purpose.

[CLINICAL AND PHARMACOLOGICAL FACTORS INFLUENCING RESISTANCE TO CLOPIDOGREL IN PATIENTS WITH CARDIOVASCULAR DISEASES].

We analysed clinical and pharmacological factors influencing resistance to clopidogrel in 250 patients with cardiovascular diseases during 18 months. It was shown that the risk ofresistance depends on the form of coronary heart disease, carbohydrate metabolism, the AA genotype of CYP2C19*2 and TBS1 genes. The cardiovascular events significantly morefrequently occurred during 12 and 18 months in resistant diabetics and in the patients with an allele lacking the *2/*3 CYP2C9 gene function and AT/TT polymorphism of the thromboxane synthase gene TBS1.

[Mechanism of development of epidemic process of group A streptococcal infection in children collectives].

Aim: To study the characteristics of group A streptococcal infection epidemic process in children aged 12 - 14 years arrived to summer camp "Orlenok" (Tuapse) from different regions of Russia.

Materials And Methods: Epidemiological (retrospective analysis of incidence of acute respiratory infections, tonsillitis, and scarlet fever), microbiological (isolation and identification of group A streptococci [GAS]), and molecular biological (pulse-electrophoresis, analysis of spe and emm genes) methods were used for the study. Objects of the study were GAS strains isolated from patients and carriers.

[Genetic characteristic of toxigenicity of group A streptococci cultures isolated from patients with tonsillitis].

Twenty-eight strains of group A streptococci (GAS) isolated from patients with lacunar and fibrinous-necrotic forms of tonsillitis during its 1st or recurrent episode were tested for presence of genes of erythrogenictoxins A, B, C, and Fusing PCR assay. Obtained results allow to consider that clinical features of the disease (severity, repeatedness, clinical form) can be determined by toxigenicity of GAS. Express identification of S.

Surgical treatment of a female patient with Turner's syndrome and a giant dissecting aneurysm of the ascending artery which occurred after two operations for aortic coarctation.

This paper reports a female patient with. Turner's syndrome and a giant aneurysm of the ascending aorta with pronounced aortic insufficiency in the presence of the bicuspid aortic valve, type II aortic dissection that occurred after two operations: resection of aortic coarctation with end-to-end anstomosis, recoarctation syndrome and aortic ascenoing-descending bypass grafting via the right-sided thoracotomy. The patient underwent prosthetics of the ascending aorta and aortic valve with ascending-descending repeated bypass grafting under conditions of complete peripheral cardiopulmonary bypass, hypothermia (22 degrees C) antegrade brain perfusion via the right subclavian artery.
