[Features of an explosive lower extremities injury protected by sapper shoes].

The purpose of the work is to conduct experimental studies that reveal the characteristic features of explosive injuries of the lower extremities using various samples of sapper protective shoes of domestic and foreign production. The subjects of experiment were the amputated by medical reasons lower extremities of a person. The severity of explosive damage during contact blasting and the parameters of shock accelerations acting on the lower extremities, as well as approximate periods of disability and the forecast of possible disability, are determined.

[Extended endoscopic endonasal posterior (transclival) approach to tumors of the clival region and ventral posterior cranial fossa. Part 1. Topographic and anatomical features of the clivus and adjacent structures].

Objective: to describe the main topographic and anatomical features of the clival region and its adjacent structures for improvement and optimization of the extended endoscopic endonasal posterior (transclival) approach for resection of tumors of the clival region and ventral posterior cranial fossa.

Material And Methods: We performed a craniometric study of 125 human skulls and a topographic anatomical study of heads of 25 cadavers, the arterial and venous bed of which was stained with colored silicone (the staining technique was developed by the authors) to visualize bed features and individual variability. Currently, we have clinical material from more than 120 surgical patients with various skull base tumors of the clival region and ventral posterior cranial fossa (chordomas, pituitary adenomas, meningiomas, cholesteatomas, etc.

Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus-the 'D-shuttle' project.

Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities.

Photodynamic inactivation of enveloped virus in protein plasma preparations by solid-phase fullerene-based photosensitizer.

Background: The problem of transfusion-transmitted infections still remains serious and actual for health care despite the detailed testing of donors. Human immunodeficiency virus, hepatitis B and C viruses and human cytomegalovirus are among the most dangerous pathogens that can be transmitted with blood. Previously, a composition consisting of fullerene layer applied on silica gel particles was shown to inactivate influenza virus up to complete loss of infectivity.

Use of nitric oxide producer L-arginine during infusion therapy of experimental hemorrhagic shock.

Experiments on rats showed that infusion of NO precursor L-arginine before bleeding enhanced their tolerance to hemorrhagic shock. When infused after blood loss as a component of saline solution, L-arginine improved efficiency of infusion therapy for hemorrhagic shock and increased survival rate of the animals.
