Factors that Determined a Positive Response to Resynchronization Therapy in Patients With Chronic Heart Failure and Cardiac Dyssynchrony. One Center Experience.

Aim: To evaluate the efficacy of cardiac resynchronization therapy (CRT) in patients with chronic heart failure (CHF) associated with cardiac dyssynchrony and to identify the factors that influence the CRT efficacy.

Material And Methods: This retrospective study included 155 patients after implantation of CRT devices. The CRT devices with a built-in cardioverter-defibrillator (CRT-D) and without it (CRT-P) were implanted in 139 (89.

Aortic valve replacement via J-shaped partial upper sternotomy: randomized trial, mid-term results.

Objective: To evaluate the effectiveness and safety of aortic valve replacement through upper partial J-shaped sternotomy compared to conventional sternotomy.

Material And Methods: There were 240 procedures of isolated aortic valve replacement for the period 2012-2017. According to inclusion criteria, 112 patients were randomized into 2 groups: group I - median sternotomy, group II - upper partial J-shaped sternotomy.

Method for Selection of New Primers for Identification of the Especially Dangerous Bacterium Acidovorax citrulli.

We propose a method for selection of new primers for identification of especially dangerous bacterium Acidovorax citrulli. A specific pair of new primers AC-1 F/R that can be used for detection and identification of A. citrulli was successfully tested.

L-Lysine-α-Oxidase: Acidovorax citrulli Bacterium Inhibitor.

Studies of the effects of Trichoderma harzianum Rifai F-180 culture fluid concentrate containing L-lysine-α-oxidase antitumor enzyme produced by the fungus and the homogenous enzyme, on ultrahazardous bacterium Acidovorax citrulli demonstrated the antibacterial activity of the concentrate. Trichoderma harzianum Rifai F-180 producing L-lysine-α-oxidase was cultured in a technological device at G. K.

Antibacterial Activity of L-Lysine-α-Oxidase from the Trichoderma.

We studied the effects of a concentrate of metabolites of Trichoderma harzianum Rifai F-180, an active producer of L-lysine-α-oxidase, and homogenous enzyme on a highly virulent bacteria Erwinia amylovora. The producer of antitumor and antiviral Trichoderma enzyme L-lysine-α-oxidase was cultured on a processing system of G. K.

Inhibition of Tobacco Ringspot Virus by the Culture Fluid of L-Lysine-α-Oxidase Producing Strain.

A producing strain of an anti-tumor and antiviral enzyme L-lysine-α-oxidase from Trichoderma was cultured using a technological device of G. K. Skryabin Institute of Biochemistry and Physiology of Microorganisms, Russian Academy of Sciences (Pushchino).

Trichoderma L-Lysine-α-Oxidase Producer Strain Culture Fluid Inhibits Impatiens Necrotic Spot Virus.

A method for PCR diagnosis of impatiens necrotic spot virus is developed. Concentrated culture fluid with active L-lysine-α-oxidase (0.54 U/ml) from Trichoderma harzianum Rifai fungus producer strain F-180 inhibits vitally hazardous impatiens necrotic spot phytovirus.

[L-Lysine-α-Oxidase in vitro Activity in Experiments on Models of Viruses Sindbis, Forest-Spring Encephalitis, Western Nile, Tyaginya and Dhori].

The antitumor effect of L-lysine-α-oxidase from the culture fluid of Trichoderma harzianum Rifai F-180 was investigated for the first time. The in vitro studies revealed its high activity on a model of the forest-spring encephalitis virus and no activity against the Sindbis, Western Nile, Tyaginya and Dhori viruses.
