The adsorption kinetics and orientational ordering of 4(')-n-octyl-4-cyanobiphenyl (8CB) liquid crystal films evaporated onto photosensitive poly(vinyl-cinnamate) (PVCN) substrates were investigated by surface optical second-harmonic generation. The adsorption rate of the first monolayer decreases with increasing degree of photochemical modification of the polymer. The in-plane orientational an...

Neuroleptic activity of methanolic extract of Benincasa hispida was assessed using apomorphine induced cage climbing model and catalepsy test in mice. Methanolic extract showed significant reduction in apomorphine induced cage climbing activity at 600 mg/kg and catalepsy in mice .The phytochemical analysis of methanolic extract showed presence of phenolic compounds and triterpene saponins, whic...

The fairly recent detection of a variety of anions in the interstellar molecular clouds have underlined the importance of realistically modelling the processes governing their abundance. To pursue this task, our earlier calculations for the radiative electron attachment (REA) rates for C4H , C6H , and C8H − are employed in the present work, within a broad network of other concurrent reactions, ...

Histone deacetylases (HDAC) that regulate gene expression are being explored as cancer therapeutic targets. In this study, we focused on HDAC6 based on its ability to inhibit cancerous Hsp90 chaperone activities by disrupting Hsp90/p23 interactions. To identify novel HDAC6 inhibitors, we used a dual-luciferase reporter system in cell culture and living mice by bioluminescence imaging (BLI). On ...

Ipomeamarone 15-hydroxylase activity was found in a microsomal fraction from cut-injured and Ceratocystis fimbriata-infected sweet potato (Ipomoea batatas Lam. cv. Norin No. 1) root tissues and its optimum pH was 8.0. The enzyme reaction required O(2) and NADPH. The K(m) values calculated for ipomeamarone and NADH were approximately 60 and 2 micromolar, respectively. NADPH alone had little effe...

Sequestration, into the ethyl trans-cinnamate, over control QQ hairpencils, of the behaviourally most active courtship pheromone component, in male Grapholita rnolesta (Busck 1916) results in an increased mating success attracted to ethyl cinnamate-treated dd moved significantly faster than 99 attracted to control Cfcf Since control dd that were successful at coupling on average took more attem...

BACKGROUND The aim of the present study was to explore the occurrence of fibrocytes in tissue and to investigate whether the appearance of fibrocytes may be linked to structural changes of the parenchyme and vasculature in the lungs of patients with obliterative bronchiolitis (OB) following lung or bone marrow transplantation. METHODS Identification of parenchyme, vasculature, and fibrocytes ...
