OBJECTIVES To estimate rates of cadmium (Cd) uptake from the digestive tract and changes in Cd in biological specimens after intake of Cd mainly in rice. METHODS Twenty-five young non-smoking Japanese female volunteers (20-23 in age) were recruited and a 20-d experimental study was conducted. With polished rice containing 0.004 ppm and 0.340 ppm of Cd, Meal L and Meal H were prepared. Approxi...

Collecting duct (CD)-specific knockout (KO) of endothelin-1 (ET-1) causes hypertension, impaired ability to excrete a Na load, and enhanced CD sensitivity to the hydrosmotic effects of vasopressin (AVP). CD express the two known ET receptors, ET(A) and ET(B); in the current study, the role of the CD ET(A) receptor in mediating ET-1 actions on this nephron segment was evaluated. The ET(A) recept...

2-Phenylpyrimidine skeleton-based multifunctional electron-transport materials are designed and synthesized. By using these materials and green phosphorescent emitter, fac-tris(2-phenylpyridine)iridium [Ir(ppy)(3)], extremely efficient green organic light-emitting devices are developed. The devices show the efficiencies of 128 lm W(-1) (105 cd A(-1)) at 100 cd m(-2) and 96 lm W(-1) (99 cd A(-1)...

BACKGROUND In Crohn disease (CD), the increased production of reactive oxygen species from activated neutrophils may reduce plasma concentrations of antioxidant vitamins and result in increased oxidative stress. OBJECTIVE We compared lipid peroxidation, a measure of reactive-oxygen-species production, and plasma antioxidant vitamin concentrations between CD patients and healthy control subjec...

Up to now, there was no document on ornamental plants that had been applied to phytoremediation, which can remedy contaminated environment and beautify it at the same time. Thus, the growth responses and possible phytoremediation ability of three ornamental plants selected from the previous preliminary experiments were further examined under single Cd or combined Cd-Pb stress. The results showe...

A pyrene-containing single-molecule excimer-emitting compound, 1,8-bis(pyren-2-yl)naphthalene (BPyN), was synthesized. With BPyN as a host emitter, C545T-based green OLEDs were fabricated, exhibiting high efficiencies of 22 lm W(-1), 22 cd A(-1) and 6.2% external quantum efficiency (EQE) at 100 cd m(-2), and 19 lm W(-1), 22 cd A(-1) and 6.2% EQE at 1000 cd m(-2).

Collecting duct (CD)-derived endothelin-1 (ET-1) exerts natriuretic, diuretic, and hypotensive effects. In vitro studies have implicated cyclooxygenase (COX) metabolites, and particularly PGE(2), as important mediators of CD ET-1 effects. However, it is unknown whether PGE(2) mediates CD-derived ET-1 actions in vivo. To test this, CD ET-1 knockout (KO) and control mice were studied. During norm...

The solubility enhancement of diazepam and nitrazepam in water was analyzed depending on temperature and amount of α-cyclodextrin (α-CD), β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD). The interactions of drug-cyclodextrin in solution were investigated by the phase-solubility analysis. Diazepam (nitrazepam) content in aqueous complexation medium was analyzed UV spectropho...
