Earlier work on mechanical properties and their relation to phase diagrams is complemented here by theological and further morphological studies using an optical microscope and polarizing light, for the system studied previously and also for three other binary blend systems. The polymer liquid crystal (PLC) is the same in all, PET/0.6PHB, where PET = poly(ethylene terephthalate), PHB = p-hydrox...

Recent results from searches for physics beyond the Standard Model (SM) in e-proton collisions at HERA at center-of-mass energies of 300 and 320 GeV are presented. They were performed on a data sample collected in the period 1994− 2004 by the H1 and ZEUS collaborations. The data have been analysed searching for leptoquarks, light gravitinos in R-parity violating supersymmetric models and magnet...

The NEMO 3 detector, now operating in the Fréjus Underground Laboratory, is devoted to search for neutrinoless double beta decay ; the expected sensitivity for the effective neutrino mass (< mν >) is on the order of 0.1 eV. The performances of the tracking detector are presented. The first and very preliminary results concerning the background and the double beta signal are given.

In present study, directly compressed controlled released matrix tablets of Diltiazem Hydrochloride were formulated at drug-to-polymer ratios (D: P) of 10:1, 10:2, 10:3 using polymers Ethocel 45 Premium, K100 LV Methocel, K15M EP Premium Methocel as rate controlling agents. In some formulations of Diltiazem hydrochloride and Ethocel 45 Premium matrices, 30% of filler was replaced by Co-excipien...

Vasodilator prostaglandin PGE(2) protects the kidney from excessive vasoconstriction during contraction of extracellular fluid volume and pathophysiological states. However, it is not yet clear which of the four known E-prostanoid (EP) receptors is localized to resistance vessels and mediates net vasodilation. In the present study, we assessed the presence, signal transduction, and actions of E...

Prostaglandin E(2) (PGE(2)), an important mediator of the inflammatory response, acts centrally to elicit sympathetic excitation. PGE(2) acts on at least four E-class prostanoid (EP) receptors known as EP(1), EP(2), EP(3), and EP(4). Since PGE(2) production within the brain is ubiquitous, the different functions of PGE(2) depend on the expression of these prostanoid receptors in specific brain ...

BACKGROUND AND AIMS Involvement of prostaglandin E(2) (PGE(2)) receptors EP(1), EP(2), and EP(4) in the formation of aberrant crypt foci (ACF) and/or intestinal polyps has been suggested. In contrast, EP(3) appears to have no influence on the early stages of colon carcinogenesis. In the present study, we examined expression of PGE(2) receptor subtypes EP(1), EP(2), EP(3), and EP(4) in normal co...

Background & Aim: This experiment was conducted to examine the effect of different levels of Echinacea purpurea (EP) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (AOA) in serum of broiler chicks. Experimental: In this trial 240 one-day-old broiler chicks (Ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 re...
