were sleeping; in these mosquitos were observed various stages of the development of the parasite. From such a study, considering the quantity of material used, we might expect, as indeed turned out to be the case, noteworthy results. Contemporaneously, mosquitos were studied, which were caught in stables and poultry yards, which, deriving their nourishment from the blood of birds and domestic ...

The aim of this study was to determine serum selenium concentrations in Polish Konik horses residing in the Odra Delta Nature Park (Poland) and to evaluate the activity of glutathione peroxidase and Se content in testes of this horse breed. In over 95% of cases, serum Se concentration was below the optimal range, and none of the horses examined was deficient in this trace element. The lack of S...

BACKGROUND AND PURPOSE The United States (US) has experienced declines in stroke mortality in contrast to the increases reported for Poland. As part of the Poland and US Agreement on Cardiovascular and Cardiopulmonary Research, stroke mortality trends in Polish and US subpopulations were compared in the context of cross-population differences in competing causes of death and determinants of str...

As a top predator, the white-tailed eagle (Haliaeetus albicilla) may serve as a good indicator species, providing information about the bioavailability of contaminants and their transfer within the food chain. In this study, we aimed to determine the common sources of origin of 17 metals and other elements in the liver of white-tailed eagles, and to compare the variations in their hepatic conce...
