Vitamin C (L-ascorbic acid) is essential for many enzymatic reactions, in which it serves to maintain prosthetic metal ions in their reduced forms (for example, Fe2+, Cu+), and for scavenging free radicals in order to protect tissues from oxidative damage. The facilitative sugar transporters of the GLUT type can transport the oxidized form of the vitamin,(More)
We have recently identified that rat organic anion transporters, polypeptide2 (oatp2) and oatp3, both of which transport thyroid hormones. However, in humans the molecular organization of the organic anion transporters has diverged, and the responsible molecule for thyroid hormone transport has not been clarified, except for human liver-specific transporter(More)
Some kinds of substances naturally attract people to touch them. The slurry made from water and starch is one of the haptically fascinating substances, and presents the amusing but mysterious sensation like playing in the mud when you were in childhood. The mysterious haptic sensation comes from the property of the fluid, "dilatancy", which is the change in(More)
In vivo dopamine receptor binding of the newly synthesized ligand, 125I-2'-iodospiperone (125I-2'-ISP), was studied in mouse brain. The highest accumulation was found in the striatum. Analysis of the striatal homogenate showed the 125I-2'-ISP to be metabolically stable. Furthermore, this striatal binding was saturable and displaced only by dopaminergic(More)
