[Combined treatment of rectal cancer with moderate risk of tumor progression].

Objective: To increase the effectiveness of combined treatment in patients with rectal cancer and moderate risk of progression based on the concept of polyradiomodification (PRM).

Material And Methods: The study included 337 patients with rectal cancer and moderate risk of tumor progression. A short course of radiotherapy (cRT) (5x5 Gy) combined with several radiomodifiers (cRT+PRM) was performed in 147 (43.

Morphological assessment of wound healing after cryodestruction of skin using an aqueous colloidal solution of C60 fullerenes.

Objective: The aim is to assess the morphological state of a cold skin wound in an experiment, using an aqueous colloidal solution of C60 fullerenes.

Patients And Methods: Materials and methods: An experimental study was conducted in 30 six-month-old male rats divided into three groups, 10 individuals in each group: group I included rats that did not undergo any manipulations; group II was represented by rats which underwent a cold wound simulation on the lateral thigh surface; group III was represented by rats who had a simulated cold wound followed by introduction of an aqueous colloidal solution of C60 fullerenes at a dose of 0.1 mg/kg for 5 days into the abdominal cavity, starting from the cryodamage day.

Morphological features of a cold skin wound under the influence of an extract of cryopreserved skin fragments of piglets (experimental study).

Objective: The aim of the study is to identify in an experiment the effect of an extract of cryopreserved fragments of piglets on the morphological state of a cold skin wound.

Patients And Methods: Materials and methods: Hairless six-month-old male rats were used in the study. They were divided into III groups: group I included 10 rats that had not been manipulated; group II was represented by 10 rats with cold wounds on the lateral surface of the thigh; group III was represented by 10 rats that were with a cold wound, followed by the injection of an extract of cryopreserved skin fragments of piglets into the abdominal cavity at a dose of 50 μg per 100 g of animal body weight (peptide concentration 100 μg/ml) once a day for 5 days from the time of wound modeling.

Radiation Risk of Cardiovascular Diseases in the Cohort of Russian Emergency Workers of the Chernobyl Accident.

This paper continues a series of publications that analyze the impact of radiation on incidence of circulatory system diseases in the cohort of Russian recovery operation workers (liquidators) and presents the results of the analysis of cardiovascular disease (CVD) incidence. The studied cohort consists of 53,772 liquidators who arrived in the Chernobyl accident zone within the first year after the accident (26 April 1986 to 26 April 1987). The individual doses varied from 0.
