Radioluminescent sources, containing as excitant agent ethyl-siloxan polymers labeled with tritium, represent the most studied constructive variants. The required high specific activities induce significant self-radiolytical processes in labeled polymers, their study being necessary for technological, radiobiological, and radioecological reasons. In the present study, the protective effect of phenyl fragments in tritium labeled ethylsiloxane structures

The aim of this study was to evaluate the effect of methyl donor biovectors as cocktail formulation in cancer therapy. Based on our previous results regarding the pharmacokinetic of [Methyl-14C] Choline and [Methyl-3H] S-Adenosyl–Methionine (SAM) in presence of Folic Acid and their properties in the regulation of transmethylation metabolism, a cocktail solution of SAM, Choline and Folic Acid was prepared taking into account the previosly established

Nandrolon is an androgenic growth promoter. This anabolic substance can be used for accelerating the increase of animal body mass. This steroid is used also in the therapy of animals like cattle, sheep or hogs and it can be found as residuum in the animal body. In a lot of countries this therapy is used abusively and, as result, results in a high level of residuals in different food stuffs such as beef and pork meat and veal liver. Because of these
