Assessment of carcinogenic risk levels to the health of population of some cities of Bashkortostan

The results of individual and population cancer risk assessment to the health of population of some cities in the Republic of Bashkortostan under the influence of air chemical pollutants and drinking water are given. Research has shown that in the examined cities, the risk to public health from air chemical contamination is higher than from drinking water contamination.Приведены результаты оценки индивидуального и популяционного канцерогенного риска для здоровья населения некоторых городов Республики Башкортостан от воздействия химических веществ, загрязняющих атмосферный воздух и питьевую воду. Исследования показали, что в настоящее время в изученных городах риск для здоровья населения от химического загрязнения атмосферного воздуха выше, чем от загрязнения питьевой воды

On likely linkage between dissociative electron attachment and biological effects produced by xenobiotics

A possible correlation between electron acceptor properties, in particular, dissociative electron attachment (DEA) and biological activity for a series of xenobiotic species (organic pollutants, polyphenolic antioxidants, and ascorbic acid) is reported. Formation and decay of temporary negative ions (TNIs) are studied using electron transmission and DEA spectroscopies. Experimental findings are assigned with the support of density functional theory calculations and are discussed in connection with the effects produced by these compounds in living cells. The basic ideas of the present study are derived from the work published in the earlier 60th of the XX century by A. Szent-Györgyi [1,2] and J. Lovelock [3]. Likely sources of electrons able to interact with xenobiotic molecules to form TNIs under cellular conditions are tentatively associated with mitochondria and cytochrome P450 enzymes. The formed TNIs are supposed to decay via the DEA mechanism producing negatively charged and neutral fragments, in analogy with those observed by DEA spectroscopy under gas-phase conditions. Electrochemical studies of reductive dehalogenation [4] and dehydrogenation [5] in solution demonstrate that TNIs can dissociate in condensed environment instead of dissipating their excess energy. Preliminary conclusions about a correlation between DEA and biochemical processes are summarized

COOPERATIVE APPLICATION OF ENDOPHYTIC STRAINS OF BEAUVERIA BASSIANA UFA-2 AND BACILLUS SUBTILIS 26Д FOR COMPREHENSIVE DEFENSE OF POTATO

Endophytic habitation of Beauveria bassiana Ufa-2 and Bacillus subtilis 24D was demonstrated. Presence of these strains decreased the level of late blight symptoms and Colorado potato beetle eating of plants.Работа выполнена при поддержке гранта двухлетних прикладных научных исследований, направленных на создание продукции и технологий, по приоритетному направлению «Науки о жизни» в рамках мероприятия 1.2 Программы Министерства образования и науки РФ № 14.604.21.0016
