Thiobarbituric acid reactant substances (TBARs) content, and the activities of glucose-6-phosphate dehydrogenase (G6PDh), citrate synthase (CS), Cu/Zn- and Mn-superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPX) were measured in the lymphoid organs (thymus, spleen, and mesenteric lymph nodes (MLN)) and skeletal muscles (gastrocnemius and soleus) of adrenodemedullated (ADM) rat...

The study evaluates the health risk caused by heavy metals to the inhabitants of a gold mining area. In this study, 56 soil samples from five mine tailings and 17 from two mine villages were collected and analyzed for Asernic (As), Lead (Pb), Mercury (Hg), Cadmium (Cd), Chromium (Cr), Cobalt (Co), Nickel (Ni), Copper (Cu) and Zinc (Zn) using ICP-MS. Measured concentrations of these heavy metals...

Photosensitizers, Zn protoporphyrin IX and Zn chlorin e6, are completely inserted into each heme pocket of a hexameric apohemoprotein. The fluorescence quenching efficiencies upon addition of methyl viologen are 2.3 and 2.6 fold-higher than those of the partially photosensitizer-inserted proteins, respectively, indicating that the energy migration occurs within the proteins.

Six Holstein steers (initial BW 335 kg) were used in a replicated 3 x 3 Latin square design to study the distribution of Zn in ruminal contents from a conventional Zn source (ZnO) or Zn sequestered to a polysaccharide (PC-Zn). Treatments consisted of a basal diet (no Zn supplementation) and the basal diet supplemented with Zn from either PC-Zn or ZnO. Steers were provided with 208, 920, or 896 ...
