Curcuminoid extract and piperine are being evaluated for beneficial effects in Alzheimer's disease, among other intractable disorders. Consequently, we studied the potential for herb-drug interactions involving cytochrome P450 (P450), UDP-glucuronosyltransferase (UGT), and sulfotransferase (SULT) enzymes. The curcuminoid extract inhibited SULT

A new solid phase extractor, nano-scale diboron trioxide/titanium dioxide composite material, was synthesized and used for separation and/or preconcentration of trace cadmium ion from various samples. The characterization of the synthesized material was performed by scanning electron microscope (SEM), transmission

CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics directly bond to bone and have potential use as a bone substitute material. The present study evaluated the toxicity from subchronic intravenous administration of CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics to male and female Sprague-Dawley rats. The rats were divided
