Exposure of Atlantic salmon smolts to estrogenic compounds is shown to compromise several aspects of smolt development. We sought to determine the underlying endocrine mechanisms of estrogen impacts on the growth hormone (GH)/insulin-like growth factor I (IGF-I) axis. Smolts in freshwater (FW) were either injected 3 times over 10 days with 2 μgg(-1) 17β-estradiol (E2) or 150μgg(-1) 4-nonylpheno...

The structural and electronic properties of sheets and nanotubes of boron are investigated using density functional theory. The calculations predict the stability of a novel reconstructed {1221} sheet over the idealized triangular {1212} sheet. Nanotubes formed by wrapping the half-metallic {1221} sheet show a curvature-induced transition in their electronic properties. Analysis of the charge d...

In the course of our studies on the role of complement in an t i se rum-media ted damage to allografts and xenografts of skin, we have observed that, whereas serum from C5 deficient mice fails, as expected, to lyse sensitized sheep erythrocytes (SRBC),I whole blood from these animals causes measurable lysis even when di luted 1:100 in saline. This lytic activity occurs only if the cells have re...

A spectrophotometric method for determining cyanogenic glucosides (CGs) was validated in accordance with IUPAC and ICH requirements for new methods. The method demonstrates good linearity in the range of 0.1-0.88 μgg hydrocyanic acid (HCN). The accuracy of the method ranges between 95.2% and 96.4%. The precision of the method, reflected as the relative standard deviation of the replicates, is l...
