A novel nontoxic form of chimeric mucosal adjuvant that combines the A subunit of mutant cholera toxin E112K with the pentameric B subunit of heat-labile enterotoxin from enterotoxigenic Escherichia coli was constructed by use of the Brevibacillus choshinensis expression system (mCTA/LTB). Nasal immunization of mice with tetanus toxoid (TT) plus mCTA/LTB(More)
A case of chondroma which occurred in the midline of the dorsum of the tongue in a 40-year-old Japanese male is reported together with a review of the literature. Histological investigation revealed that this lingual chondroma had the characteristics of hyaline cartilage. We regard the metaplastic transformation theory as the best explanation of(More)

L-Citrulline, the effective precursor of L-arginine which is essential as a substrate for endothelial NO synthase (eNOS), is effective in enhancing NO-dependent signaling. However, little is known about the efficacy(More)
BACKGROUND Menaquinone-4 is a type of vitamin K that has a physiological function in maintaining bone quality via γ-carboxylation of osteocalcin.

PURPOSE Glutathione is a tripeptide consisting of cysteine, glycine, and glutamate and functions as a major antioxidant. It is synthesized endogenously in humans. Glutathione protects thiol protein groups from oxidation and is involved in cellular detoxification for maintenance of the cell environment. Reduced glutathione (GSH) has a skin-whitening effect(More)
