Using a microdialysis technique, we continuously infused D-kynurenine (KYN) (0, 50, and 100 microM) into the prefrontal cortices (PFCs) of male Sprague-Dawley rats. We then used column-switching high-performance liquid chromatography to assess the alterations in the concentration of kynurenic acid (KYNA)-an antagonist of N-methyl-D-aspartate and alpha7(More)
The concentration of brain N-acetylaspartic acid (NAA) in mice was determined by high-performance liquid chromatography (HPLC) using fluorescence detection after pre-column derivatization with 4-N,N-dimethylaminosulfonyl-7-N-(2-aminoethyl)amino-2,1,3-benzoxadiazole (DBD-ED). Six different brain parts, namely, the prefrontal cortex, olfactory bulb, nucleus(More)
Kynurenic acid (KYNA), an endogenous antagonist of N-methyl-D-aspartate and α(7) nicotinic acetylcholine receptors, is one of the L-tryptophan (Trp) metabolites. To compare the level of KYNA produced in the striatum of rats after independent administration of L-Trp and D-Trp, rats were intraperitoneally administered L-Trp and/or D-Trp (100 mg/kg), and a(More)
Satellite cells are maintained in an undifferentiated quiescent state, but during muscle regeneration they acquire an activated stage, and initiate to proliferate and differentiate as myoblasts. The transmembrane protein teneurin-4 (Ten-4) is specifically expressed in the quiescent satellite cells; however, its cellular and molecular functions remain(More)
Incorporation profiles of d-Trp and l-Trp into the striatum following intraperitoneal (i.p.) administration of d-Trp or l-Trp in male Sprague-Dawley rats (100mg/kg) were investigated by using a brain microdialysis technique. Alterations in the extracellular dopamine (DA) concentration in the rat striatum were also examined. Incorporation profiles of d-Trp(More)
