TL;DR: The HCV core protein alters the oxidant/antioxidant state in the liver in the absence of inflammation and may thereby contribute to or facilitate, at least in part, the development of HCC in HCV infection.
Journal ArticleDOI

TL;DR: The ineffectiveness of oral administration of vancomycin to silkworms is due to a lack of intestinal absorption, and chloramphenicol, which is effective by oral administration, appeared in the silkworm hemolymph soon after injection into the midgut, whereas vancomYcin did not.
Journal ArticleDOI
Regional distribution and postnatal changes of d-amino acids in rat brain
TL;DR: The results described in this paper suggested that distinct regulatory mechanisms exist for individual D-amino acids in the corresponding region of rat brain.
Journal ArticleDOI
Derivatization reagents in liquid chromatography/electrospray ionization tandem mass spectrometry.
TL;DR: In this review, an overview of the derivatization reagents which have been applied to LC/ESI-MS/MS is presented, focusing on the applications to low molecular weight compounds.
Journal ArticleDOI
Fluorogenic and fluorescent labeling reagents with a benzofurazan skeleton.
TL;DR: Fluorogenic and fluorescent labeling reagents having a benzofurazan skeleton such as 4-fluoro-7-nitro-2,1,3-benzoxadiazole (NBD-F), 4-N,N-dimethylaminosulfonyl-7’sulfonate-4-sulf onate (SBD-SBD) and 4-hydrazino- 7-nitrodiazole-2-1
