We examined the distribution of Fe, Mn, Cu, Zn, and Pb in one core metalliferous, non-mineralized (background) carbonate sediments (located 69 km northwards), from Pobeda hydrothermal field. Mechanisms metal accumulation (12 samples) were evaluated based on sequential extraction geochemical fractions, including mobile (exchangeable complex, authigenic Fe-Mn hydroxides, sulfides), lithogenic (fi...

Recent studies propose that sigma site ligands antagonize N-methyl-D-aspartate (NMDA) receptors by either direct, or indirect mechanisms of inhibition. To investigate this question further we used electrical recordings to assay actions of seventeen structurally diverse sigma site ligands on three diheteromeric subunit combinations of cloned rat NMDA receptors expressed in Xenopus oocytes: NR1a ...

background: il-17 is a major cytokine player in t cell mediated leukocyte associated inflammation. il-17 is also recognized to participate in the pathophysiology of asthma. objective: to determine the role of il-17 in predicting severe asthma. methods: we obtained serum samples from asthmatic children under the age of 5-year in three different groups of mild (n=33), moderate (n=28) and severe (...
