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...

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 purpose of this study was to determine the antioxidant effect of fucoxanthin. After rats were fed a normal fat diet (NF), high fat diet (HF), and high fat with 0.2% fucoxanthin diet (HF + Fxn) for 4 weeks, the markers of oxidative stress and antioxidant capacity like lipid peroxidation, plasma total antioxidant capacity (TAC), and activities of antioxidant enzymes (catalase, superoxide dism...

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:...

PURPOSE Many chemical compounds and infectious agents such as viruses induce liver damage like necrosis or fulminant hepatic failure which is sometimes difficult to manage by medical therapies. The induced liver necrosis by carbon tetrachloride (CCl4) and thioacetamide (TAA) are exemplary models for experimental liver necrosis caused by oxygen free radicals. The aim of this study was to investi...

High intake of fish has been associated with reduced risk of CHD. The high content of n-3 polyunsaturated fatty acids (PUFA) in fish has been suggested to be a protective factor. In addition, fish is the entirely dominating source of methylmercury for the general population, and the concentration of Hg in erythrocytes (Ery-Hg) is often used as an index of fish consumption. Our aim was to study ...
