Autor: O. N. Kosyreva, S. A. Dobrotin, V. I. Logutov, V. I. Abdrakhmanov

Publikováno v: Journal of Analytical Chemistry. 76:641-652

In the qualitative analysis of complex mixtures of unknown composition, a promising direction for increasing the reliability of the identification of substances is the joint use of several simultaneously determined analytical parameters. A combinatio

Optimization of electrostatic field configuration in a gas-analysis detector for ion mobility spectrometry

Autor: S. A. Dobrotin, A. A. Popov

Publikováno v: Russian Journal of Nondestructive Testing. 36:135-139

A method for upgrading selective properties of a detector in an ion-mobility spectrometer is described. The method is based on modeling the device in an electrolytic cell and shows promise for improving an electric field configuration in ion detector

[Ways to improve the results of mitral valve prosthesis by preservation of the posterior cusp with the subcuspal structures]

Autor: S S, Dobrotin, S V, Bogdanovich, E N, Zemskova

Publikováno v: Vestnik khirurgii imeni I. I. Grekova. 159(3)

Prosthesing the mitral valve with preservation of the posterior cusp was performed in 156 patients. The domestic disk prostheses "Liks", "Emiks" and the bicuspid prosthesis "Medinzh" were used for the implantation. An additional correction of the tri

[Rupture of the posterior wall of the left ventricle after mitral valve prosthesis]

Autor: S S, Dobrotin, S V, Bogdanovich

Publikováno v: Vestnik khirurgii imeni I. I. Grekova. 156(2)

Rupture of the posterior wall of the left ventricle took place in 17 (1.2%) out of 1447 patients operated upon for the replacement of the mitral valve. Among them there were 13 13 early and 4 delayed ruptures. The methods used for liquidation of this

[The results of the surgical treatment of recurrent mitral stenosis under artificial circulation]

Autor: S S, Dobrotin, V A, Chiginev, E N, Zemskova, A P, Medvedev

Publikováno v: Grudnaia i serdechno-sosudistaia khirurgiia. (2)

A total of 533 operations for recurrent mitral stenosis have been performed since 1987. Two hundred and twenty-six patients were operated on under extracorporeal circulation. Indications for open correction of the abnormality as an alternative to tra

[Plastic correction of aortic stenosis in two- and three heart valve diseases]

Autor: S S, Dobrotin, A P, Medvedev, V A, Chiginev, E N, Zemskova, A B, Gamzaev, O R, Lysina

Publikováno v: Grudnaia i serdechno-sosudistaia khirurgiia. (8)

Plastic correction of aortic stenosis with simultaneous intervention on the mitral and, in some cases, on the tricuspid valve was performed on 50 patients whose ages ranged from 25 to 53 years (average age 43.2 years); 15 were in NYHA functional clas
