An ion-pair, reverse-phase, high-performance liquid chromatography method of assay was developed and used in a series of rate studies carried out with the enzyme chicken liver NAD+ kinase (ATP:NAD+ 2'-phosphotransferase, EC 2.7.1.23). Complete separation of all products and reactants was

A facile and efficient synthesis of substituted indeno[2,1-c]quinolin-6(7H)-ones from a variety of α-acyl N-arylcinnamamides mediated by polyphosphoric acid (PPA) is described, and a mechanism involving the formation of a dicationic superelectrophile and subsequent double intramolecular nucleophilic cyclization reactions is proposed.

To evaluate the effect of polyphosphoric acid (PPA) pre-treatment of titanium (Ti) on the initial attachment, proliferation, and differentiation of mouse osteoblast-like cells (MC3T3-E1). Adsorption of PPA to Ti was achieved by immersing Ti disks (15 mm in diameter) into

A major challenge to the successful clinical application of bioengineered cartilage remains its integration to surrounding tissues upon implantation. One way to address this consists of generating biphasic constructs composed of articular cartilage formed in vitro on the top surface
