Study of Viral Coinfection of the Ticks Feeding on Humans in a Natural Focus of the South of the Far East.

The phenomenon of pathogen co-infection detected in a half-fed tick taken from a human in the south of the Far East was studied. Research was carried out on , , and cell lines, outbred mice, and chicken embryos using ELISA, PCR, IMFA, plaque formation, and electron microscopy. The tick contained an antigen and a genetic marker of the tick-borne encephalitis virus (TBEV).

Metabolic Restructuring in the Liver under Conditions of Endogenous Intoxication.

Significant metabolic alterations in the liver were observed in dogs with modeled acute peritonitis. These changes significantly impaired detoxification function of the liver, which was seen from the increase in the titer of toxic products in the early post-surgery period not only in the lymph, but also in the blood plasma. The key pathogenic mechanism leading to acute liver failure is destabilization of cell membrane resulting from LPO, phospholipase activity, and tissue hypoxia.

Temporal dynamics and population genetic structure of Fusarium graminearum in the upper Midwestern United States.

Fusarium graminearum sensu stricto causes Fusarium head blight (FHB) in wheat and barley, and contaminates grains with several trichothecene mycotoxins, causing destructive yield losses and economic impact in the United States. Recently, a F. graminearum strain collected from Minnesota (MN) was determined to produce a novel trichothecene toxin, called NX-2.

[Optimization of treatment of septic wounds in patients with diabetic foot ulcers].

An analysis of complex examination and treatment was made in 116 patients with necrotic suppurative complications. Patients were divided into two statistically homogeneous groups. An ointment "Levomekol" was used in control group and immobilized forms of chlorhexidine bigluconate was applied in the main group.

[FLASH-PCR diagnostics of toxigenic fungi of the genus Fusarium].

A test system for the diagnostics and identification of seven toxigenic fungi causing fusarioses of cereals (Fusarium graminearum, F. culmorum, F. poae, F.

[Diagnostics of phytopathogen fungi Septoria tritici and Stagonospora nodorum by fluorescent amplification-based specific hybridization (FLASH) PCR].

A PCR system in the fluorescent amplification-based specific hybridization (FLASH) format was developed for the detection and identification of two important wheat pathogenic fungi Septoria tritici (teleomorph of Mycosphaerella graminicola and Stagonospora nodorum (teleomorph of Phaeosphaeria nodorum), which cause spots on leaves and glumes, respectively. The pathogen detection system is based on the amplification of a genome fragment in the internal transcribed spacer 1 (ITS 1) region and a site encoding the 5.8S ribosomal RNA.

[The pathogenesis and surgical treatment of trophic ulcers of the lower extremities against a background of varicose veins].

The state of the musculo-venous pump of lower extremities was studied in 72 patients with trophic ulcers caused by varicose disease. The methods used were: phlebotonometry, phleboplethysmography, US dopplerography, distal ascending and retrograde-femoral, popliteal and talocrural phlebography. It was established that ectasia and/or valve incompetence of deep and muscle veins of the lower extremities with the formation of blood refluxes along the profound, communicating and superficial veins underlie the disturbances of venous hemodynamics.

[The mechanisms of the development of decompensated forms of varicose veins].

The functional (rheovasography, photoplethysmography), ultrasonic (dopplerography) and roentgenological (distal ascending and retrograde popliteal and talocrural phlebography) methods of investigation were used for studying the state of the musculo-venous pump of the crus in 50 patients with the varicose disease in the stage of trophic disorders. It was established that the formation of pathological capacities in the crural muscular veins and leakage of blood from the posterior tibial into deep plantar veins was responsible for the development of the decompensated course of this disease.

[The pathogenetic validation of the volume and the technology for the surgical correction of disorders in the musculo-venous pump of the lower extremities in patients with decompensated forms of varicose veins].

The state of the venous, capillary blood circulation and lymph flow was studied in 70 patients with varicose disease at the stage of trophic disorders with the help of photoplethysmography, rheovasography, dopplerography, distal ascending and retrograde femoral, popliteal, talocrural phlebography, lymphography. It was established that a sharp disturbance of the musculo-venous pump function caused decompensation of not only the venous blood circulation but also the lymph flow, while the removal of the subcutaneous veins of the crus is not possible without deterioration of the lymphatic drainage. The authors propose not to ablate the main trunks of the subcutaneous veins on the crus but to perform occlusion of the autovein ablated from the femur.
