The current work reports on the development of Au nanoparticles (NPs) supported titania membrane towards enhancing catalytic reduction p-nitrophenol. Titania was successfully fabricated via chemical anodization method at 50 V in ethylene glycol: water as electrolyte. A well-ordered nanotubular array 138±18 nm pore diameter observed by electron microscope. NPs were deposited form (Au/TiO2 MF) im...

Human aryl sulphotransferase (HAST) 1, HAST3, HAST4 and HAST4v share greater than 90% sequence identity, but vary markedly in their ability to catalyse the sulphonation of dopamine and p-nitrophenol. In order to investigate the amino acid(s) involved in determining differing substrate specificities of HASTs, a range of chimaeric HAST proteins were constructed. Analysis of chimaeric substrate sp...

OBJECTIVE To evaluate cell cultures derived from intrasynovial nodules from a patient with primary synovial chondromatosis (PSC) for aberrant numbers/differentiation of osteochondroprogenitor cells. METHODS Cell cultures were established from PSC synovial nodules, or normal bovine or human osteoarthritis (OA) synovia (for comparison). Multi-lineage potential was determined using well-characte...
