Plane-wave pseudopotential Density Functional Theory (OFT) periodic slab calculations were performed usingthe giteralized gradient approximation (GHA) to investigate the adsorption of nitric oxide(NO) on the (I II)surface of Cu. Copper rface was stimulated using th P 'odic Slab Method consisting of Five atomic Layers.Four different adsorption saes (Atop. Bridge, RCP Hollow, and FCC Hollow) were...

Crystalline solids self-assembled from anionic and cationic porphyrins provide a new class of multifunctional optoelectronic micro- and nanomaterials. A 1 : 1 combination of zinc(II) tetra(4-sulfonatophenyl)porphyrin (ZnTPPS) and tin(IV) tetra(N-methyl-4-pyridiniumyl)porphyrin (SnTNMePyP) gives porphyrin nanosheets with high aspect ratios and varying thickness. The room temperature preparation ...

The effect of cell replication on histone-carcinogen adducts was investigated by determining the specific adduct levels as a function of time following carcinogen treatment of human TK6 cells grown in culture. Core histones isolated from cells treated with aflatoxin B1 or r-7,t-8 dihydroxy-t-9,t-10-epoxy-7,8,9,10-tetrahydrobenzo[a]pyrene exhibited a decrease over five generations in specific ad...

approximate conditions in natural ecosystems, managed ecosystems are characterized by a substantial organic matter export mainly as harvest (e.g. Schulze et al. 2009). Given that currently ca. 12% of the global land area of ca. 13.4 Gha is cropped and ca. 26% used as pastures, the role of carbon exports needs to be addressed or, in case I misunderstood, the procedure of how inputs were derived ...

Four dihydroxy flavone derivatives viz 5,3′-, 7,3′-, 2′,3′and 2′,4′-dihydroxy flavones were evaluated for their antinociceptive response in doses ranging from 3 to 200 mg/kg (s.c). Antinociception in mice was studied employing acetic acid induced abdominal constrictions, formalin induced nociception and tail immersion assay procedures. Involvement of opioid mechanism in the antinociceptive acti...

BACKGROUND Setipiprant, a tetrahydropyridoindole derivative, is a CRTH2 (chemoattractant receptor-homologous molecule expressed on T-helper [Th]-2 cells) antagonist that has the potential to be effective in the treatment of patients with diseases with an allergic etiology, such as allergic rhinitis and asthma. OBJECTIVES This study investigated the disposition, metabolism, and elimination of ...
