[Prognostic factors of recurrent acute cerebrovascular incidents in patients with ischemic stroke].

Objective: To establish prognostic factors of recurrent acute cerebrovascular complications after ischemic stroke.

Material And Methods: A prospective observational study on the 21-22nd day of the acute stage of ischemic stroke included 148 patients, aged 60 [5; 68] years. Following the discharge, a unified telephone survey of patients or their relatives was performed every 3 months.

Genetic characterization of the M RNA segment of Crimean-Congo hemorrhagic fever virus strains isolated in Russia and Tajikistan.

The data on the structure of the M genome segment of CCHF virus strains from Russia and Central Asia (Tajikistan) are presented. Data obtained have been compared with other available published sequences of the middle segment of strains from China, Nigeria, and Pakistan. It has been found that all the known strains can be divided into four genetic groups, based on the nucleotide sequence of the M genome segment and an amino acid sequence of the glycoprotein precursor it encodes, whereas VLG/TI29414 and STV/HU29223 strains from Russia form a separate group.

[Longitudinal radioisotope tomograph].

To-day the construction of an apparatus for longitudinal emissive tomography has become a problem of great urgency. The designed apparatus, as described herein, is based on the principle of the image superposition method and the results obtained are suggestive of possibilities for its efficient application in diagnosing diseases involving large organs, such as the brain, liver, etc.
