[The role of employers in ensuring working conditions conducive to the health of medical workers].

The article examines the normative, conceptual and ethical aspects of employers' responsibility for creating jobs that reduce risks and ensure the health of medical workers. An overview of the normative documentation of the World Health Organization and the International Labor Organization is presented, data reflecting the morbidity of health workers due to a weak degree of protection in the workplace are presented. It is concluded that the high degree of not formal, but real responsibility of the employer for ensuring working conditions conducive to the health of medical workers has a positive effect on their loyalty, reduces staff turnover, ensures the effectiveness and sustainability of the organization in the medical services market.

[The health issues in self-appraisal of workers of industrial production and social sector].

[The corporative programs of prevention of occupational diseases].

The prevention of occupational and production-conditioned diseases is expressed in complex of systemic measures of medical (sanitary epidemiological, sanitary hygienic, medical preventive, etc.) and non-medical (state, public, economic, legal, technical, organizational technical, environmental, etc.) nature, targeted to decrease risk of developing diseases and deviations in health of employees, to prevent or slow down their progression and to decrease development of unfavorable consequences.

Genetically encodable bioluminescent system from fungi.

Bioluminescence is found across the entire tree of life, conferring a spectacular set of visually oriented functions from attracting mates to scaring off predators. Half a dozen different luciferins, molecules that emit light when enzymatically oxidized, are known. However, just one biochemical pathway for luciferin biosynthesis has been described in full, which is found only in bacteria.

Neuroprotective effects of individual or combined exposure to hypoxia and hypercapnia in the experiment.

We studied the effects of hypoxic, hypercapnic, and hypercapnic-hypoxic exposures on brain tolerance to ischemia. All respiratory training modes had a neuroprotective effect, but the most pronounced effect was observed after exposure to hypercapnic hypoxia. Experimental stroke in rats preliminary exposed to hypercapnic hypoxia was associated with minimal neurological deficit and motor coordination disturbances in comparison with training modes.
