A series of poly(phenylene-vinylene)s (PPV) was synthesized with two monomer building blocks containing methoxy and 2-ethylhexyloxy (MEH) sidechains sterically bulky fluorenyloxy sidechain. Variations in incorporation were achieved by...

The tumor suppressor protein p53 is a transcription factor that regulates apoptotic responses produced by genotoxic agents. Previous studies have reported that 7,12-dimethylbenz[a]anthracene (DMBA)-induced bone marrow toxicity is p53-dependent in vivo. Our laboratory has shown that DMBA-induced splenic immunosuppression is CYP1B1- and microsomal epoxide hydrolase (mEH)-dependent, demonstrating ...

Six different 1,2-epoxycycloalkanes, whose rings were constituted of 5 to 12 carbon atoms, were tested as possible inhibitors of epoxide-metabolizing enzymes and substrates for the microsomal and cytosolic epoxide hydrolases (mEH, cEH) in mouse liver. The geometric configurations and the relative steric hindrances of these epoxides were estimated from their ease of hydrolysis in acidic conditio...

The Arabidopsis thaliana genome contains two genes encoding NAD-MEs [NAD-dependent malic enzymes; NAD-ME1 (TAIR accession number At4G13560) and NAD-ME2 (TAIR accession number At4G00570)]. The encoded proteins are localized to mitochondria and assemble as homo- and hetero- dimers in vitro and in vivo. In the present work, the kinetic mechanisms of NAD-ME1 and -ME2 homodimers and NAD-MEH (NAD-ME ...

Microsomal epoxide hydrolase (mEH) is a bifunctional protein that plays a central role in the metabolism of numerous xenobiotics as well as mediating the sodium-dependent transport of bile acids into hepatocytes. These compounds are involved in cholesterol homeostasis, lipid digestion, excretion of xenobiotics and the regulation of several nuclear receptors and signaling transduction pathways. ...

In this study we have synthesized ZnO nanoparticles of rod-like, sphere-like and flower-like structure in solvothermal route by using different capping agent. With the help of XRD data, using Shearer’s equation the average particle size of different morphologies were calculated as 86, 57 and 26 nm for flower-like, sphere-like and rod-like ZnO respectively. The direct band gap energies of the na...
