Chlamydia trachomatis, Mycoplasma genitalium and Ureaplasma urealyticum in clinical and non-clinical settings, Arkhangelsk Oblast, Russia.

Russia and Eastern Europe have the fastest growing HIV epidemic in the world. As sexually transmitted infections (STIs) play an important role in HIV transmission, we conducted this study to find the prevalence of three microorganisms associated with STIs in Arkhangelsk Oblast, Russia.

[Joint prosthetics using carbon implants].

A group of "Intost" materials based on carbon were developed by the I. M. Sechenov Moscow Medical Academy jointly with the Research Institute of Graphite.

[Comminuted intra-articular fractures of the calcaneus].

The article analyzes 31 operations of arthrodesis of the talocalcaneonavicular joint performed at early terms after trauma in patients with comminuted intraarticular fractures of the heel bone. Long-term results of the treatment were followed-up during 6 months-6 years. It was shown that early arthrodesis of the talocalcaneonavicular joint made the terms of invalidism shorter and reduced considerably the percentage of invalidism in patients with severe intraarticular fractures of the heel bone.

[The action of gamma irradiation on terrilytin immobilized on cellulose-fiber materials].

The effect of gamma-radiation on terrilytin, a proteolytic enzyme immobilized on modified and nonmodified cellulose materials was studied by EPR. Dialdehyde cellulose and graft copolymer of cellulose and polyacrylic acid were used as the modified cellulose materials. Dependence of the native and immobilized terrilytin activity and the content of free radicals in the irradiated samples on the irradiation dose was observed.
