In this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (NNH) as a newly synthesized modifier and TiO2 nanoparticles to the carbon paste (MTCPE) and then was used for the electroanalysis of epinephrine (EP). The electrochemical studies were carried out by using cyclic voltammetry, chronoamperom...

Four E-prostanoid (EP) receptors, designated EP(1), EP(2), EP(3), and EP(4), mediate the cellular effects of prostaglandin E(2) (PGE(2)). The present studies pharmacologically characterize the vasopressor and vasodepressor EP receptors in wild-type mice (EP(2)(+/+) mice) and mice with targeted disruption of the EP(2) receptor (EP(2)(-/-) mice). Mean arterial pressure (MAP) was measured via a ca...

ASL is gearing up for change in looks, content as well as its name. About 27 years after it was launched, ASL is undergoing a complete transformation to meet fresh challenges of the new millennium. The journal will have a new look and feel, its advisory committee reconstituted, a more efficient peer review process and an online platform for submission and review of research papers. Very soon, a...

Taking for granted an ontological standpoint independent of any empirical or epistemological perspective, philosophical theories of properties are actually quite rarely adopted in the knowledge representation community. The theory of qualities introduced in the DOLCE-CORE ontology [4] allows for representing different viewpoints on the world in a unified framework but it does not refer to any p...

While some researchers have questioned the efficacy of corrective feedback (CF), other researchers believe that CF can be effective if implemented through new technology types, including e-portfolio (EP). However, whether EP can be used as a medium of providing CF for language learners at different levels of language proficiency is still unknown. The purpose of the present study, therefore, was...

PGE(2) is a potent stimulator of renin release. So far, the contribution of each of the four PGE(2) receptor subtypes (EP(1)-EP(4)) in the regulation of renin release has not been characterized. Therefore, we investigated the effects PGE(2) on renin secretion rates (RSR) from isolated, perfused kidneys of EP(1)-/-, EP(2)-/-, EP(3)-/-, EP(4)-/-, and wild-type mice. PGE(2) concentration dependent...
