Peroxynitrite-induced relaxation of isolated vessels may involve the formation of S-nitrosothiols. This study characterized the hemodynamic effects of systemically injected peroxynitrite in pentobarbital sodium-anesthetized rats and determined whether these effects were due to the formation of S-nitrosothiols. We utilizedl-penicillamine, which attenuates the hemodynamic effects of systemically ...

The body concentrations of Ag in a top marine predator, the whelk Thais clavigera, varied significantly (1.10 to 4.67 μg g–1 dry wt) in individuals collected from 3 intertidal rocky shores in Hong Kong, whereas there was no significant difference in Ag concentrations in species from lower trophic levels (macroalgae Ulva sp. and rocky oyster Saccostrea cucullata). We compared the variation in Ag...

Abstract In this work, we perform a systematical investigation about the possible hidden and doubly heavy molecular states with open strangeness from interactions of $$D^{(*)}{{\bar{D}}}^{(*)}_{s}$$ D ( ∗ ) <mml:...
