Procena nedeljnog unosa žive preko konzumiranja ribe u srpskoj populaciji

Zahvaljujući sadržaju visoko kvalitetnih proteina, vitamina, makro i mikroelemenata, kao i omega-3 polinezasićenih masnih kiselina, riba predstavlja značajnu namirnicu u ishrani ljudi. Međutim, povećanim unosom ribe unosi se i veća količina kontaminanata, posebno žive. Koncentracija žive određivana je u mišićnom tkivu riba koje imaju veliku zastupljenost u ishrani stanovništva Srbije – osliću, skuši, šaranu i pastrmci, kao i u proizvodima od tune. Svi ispitani uzorci sadrže živu ispod maksimalno dozvoljene količine regulisane evropskim i srpskim regulativama. Procenjeni nedeljni unos žive preko konzumirane ribe, ispod je preporučenog maksimalnog limita Svetske zdravstvene organizacije

Comparison of Essential Metals in Different Pork Meat Cuts from the Serbian Market

AbstractPork consumption in Serbia accounts for a large share of total meat consumption. Pork is valuable sources of nutrients. We analyzed metal content in three different cuts of pork collected from the Serbian market during 2014. Analyses of the following isotopes: zinc (66Zn), copper (63Cu) and iron (57Fe) were performed by ICP-MS. Our data show that Zn, Cu and Fe were present in significantly different levels in hind leg, loin and shoulder, and that shoulder meat was richest in the analyzed metals. The differing mineral status of different pork cuts implies differences in their nutritional benefits for the human diet

Socially-Responsible Operations and Redesign of Health Care Institutions

Corporate social responsibility is gaining increasing importance in our region, representing the business model of the European market. Necessary to redesign the economic and non-economic enterprises in order to form the conscience of all business entities in the system moving along with the fundamental tendency of the state in obtaining membership in the European Union. Instruments, are included in the realization of knowledge capital to create mechanisms responsible society and relations between unparedjenja subjektia in the health care system. One of the instruments investigated social responsibility is emotional intelligence. Without adequate human resources with all their rights in employment, there is no introduction and application of CSR principles

Agmatine protection against chlorpromazine-induced forebrain cortex injury in rats

This study was conducted to investigate whether agmatine (AGM) provides protection against oxidative stress induced by treatment with chlorpromazine (CPZ) in Wistar rats. In addition, the role of reactive oxygen species and efficiency of antioxidant protection in the brain homogenates of forebrain cortexes prepared 48 h after treatment were investigated. Chlorpromazine was applied intraperitoneally (i.p.) in single dose of 38.7 mg/kg body weight (BW) The second group was treated with both CPZ and AGM (75 mg/kg BW). The control group was treated with 0.9\% saline solution in the same manner. All tested compounds were administered i.p. in a single dose. Rats were sacrificed by decapitation 48 h after treatment Treatment with AGM significantly attenuated the oxidative stress parameters and restored antioxidant capacity in the forebrain cortex. The data indicated that i.p. administered AGM exerted antioxidant action in CPZ-treated animals. Moreover, reactive astrocytes and microglia may contribute to secondary nerve-cell damage and participate in the balance of destructive vs. protective actions involved in the pathogenesis after poisoning.Ministry of Education, Science and Technological Development of the Republic of Serbia {[}III41014]; Military Medical Academy {[}MBMA/3/13-15, MBMA/6/15-17
