Grafting from a Hybrid DNA-Covalent Polymer by the Hybridization Chain Reaction.

Nucleic acid-polymer conjugates are an attractive class of materials endowed with tunable and responsive character. Herein, we exploit the dynamic character of nucleic acids in the preparation of hybrid DNA-covalent polymers with extendable grafts by the hybridization chain reaction. Addition of DNA hairpins to an initiator DNA-dextran graft copolymer resulted in the growth of the DNA grafts as evidenced by various characterization techniques over several length scales.

[Prophylaxis of thrombohemorrhagic complications in surgical treatment of chemoresistant pulmonary tuberculosis].

Analysis of thrombohemorrhagic complications was conducted in 98 patients, operated on for various forms of chemoresistant pulmonary tuberculosis. To prevent such complications it is necessary to prescribe heparin in minimal doses or fraxiparine preoperatively and intraoperatively. It permits to lower the prethrombotic background significantly, to prevent thrombohemorrhagic complications, and in their incidence--to eliminate thrombotic and hemorrhagic clinical features with minimal losses.

[A panel of microsatellite loci for population studies of Sakhalin taimen Parahucho perryi (Brevoort)].

Using DNA samples of Sakhalin taimen and a set of microsatellite loci, earlier reported for other salmonid fishes (Salmonidae), successful cross-species amplification was performed. A total of 56 Sakhalin taimen (Parahucho perryi) samples from the Daga, Nabil, Poronai, and Agnevo rivers (Sakhalin Island) were examined at 36 microsatellite loci, most ofwhich were described for other species and first tested in taimen. Among the 21 loci first tested in taimen, two loci produced no amplification products.

[AIDS-associated sarcoma Kaposi: features of clinical manifestations, dynamics on a background of antiretroviral therapy].

Features of a clinical current of a sarcoma of Kaposi at a HIV-infected of patients are described. It is shown that treatment combined antiretroviral therapy, with application protease inhibitors, leads to full regress of skin elements in 12 months that allows to improve quality of life of patients, and adjusts on the favorable forecast.

[Analysis of lethality in the injured persons, suffering cranioabdominal trauma].

The now observed enhancement of a human traumatism due to a traffic accidents occurrence demands the measures application, aimed on the improvement of results of the injured persons treatment. With this objective a retrospective analysis of the patients cases charts and of a court-medical expertise protocols was made of 161 injured persons, 69 of whom have died. Cranioabdominal trauma occupies a leading place in a tanatogenesis structure.
