Although the enzymatic synthesis of S-adenosylmethionine was accomplished several years ago (l), there have, as yet, been few reports of experiments with this compound. The main reason for the paucity of data appears to be the difficulty of obtaining S-adenosylmethionine in adequate quantities at a reasonable expenditure of time and starting material. Cantoni (2) has prepared S-adenosylmethioni...

Different genera and species of gram-positive, catalase-negative cocci are pathogenic to fish. The numbers of infections caused by these microorganisms have increased during the last decade, and such infections are responsible for significant economic losses in the fish farm industry (9). Identification of these bacteria can be difficult when using conventional microbiological criteria, and the...

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 ...

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:...
