A glassy carbon electrode modified with ruthenium red and functionalized multi-walled carbon nanotube has been developed. The electrochemical response characteristics of the modified electrode toward epinephrine (EP) and acetaminophen (AC) was investigated by differential pulse voltammetry (DPV). Linear calibration plots were obtained over the range of 0.3 - 333.3 μM for both EP and AC with sen...
A stable electroactive thin film of poly(caffeic acid) has been deposited on the surface of a glassy carbon electrode by potentiostatic technique in an aqueous solution containing caffeic acid. The voltammetric behavior of epinephrine (EP) at the poly(caffeic acid) modified glassy carbon electrode was studied by cyclic voltammetry. The poly(caffeic acid) modified electrode exhibited a promotion...
A simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (NE) and epinephrine (EP), in serum samples was developed. The method is based on the fluorescence sensitization of terbium (Tb3+) by complexation with both catecholamines in the presence of lanthanum (La3+), as a co-cation, and in a Na...

The objective of this study was to determine the effects of plane of nutrition during early and mid-pregnancy on the performance of mature ewes and their offspring. From day 0 to day 39 post mating (early pregnancy, EP), 82 multiparous ewes were fed to provide either 60% (low, L), 100% (medium, M) or 200% (high, H) of predicted metabolisable energy (ME) requirements for maintenance, following a...
Kuslmer et r:r.Z [9], [10] have posed the problem of characterising the "EP" ftulction f(S) for which E(f(S)) = A fer), whenever the m x mmatrix S has the Wishart distribution n W(m,n,L). In this article, we obtain integral representations for all non-negative EP ftmctions. It is also shown that any botulded EP ftulction is harmonic, and that EP polynomials may be used to approximate the flmcti...
A kinetic fluorometric method was proposed for the quantitative determination of epinephrine (EP) in human plasma samples with the aid of second-order calibration methods based on alternating trilinear decomposition (ATLD) and alternating fitting residue (AFR) algorithms. It was based on that EP could be gradually converted to a highly fluorescent intermediate product by an oxidation reaction, ...
INTRODUCTION The response to exogenous epinephrine (Ep) is difficult to predict given the multitude of factors involved such as broad pharmacokinetic and pharmacodynamic between-subject variabilities, which may be more pronounced in children. We investigated the pharmacokinetics and pharmacodynamics of Ep, co-administered with milrinone, in children who underwent open heart surgical repair for ...
Intracellular microelectrode techniques were used to characterize the electrical responses of the bovine retinal pigment epithelium (RPE)-choroid to epinephrine (EP) and several other catecholamines that are putative paracrine signals between the neural retina and the RPE. Nanomolar amounts of EP or norepinephrine (NEP), added to the apical bath, caused a series of conductance and voltage chang...
Introduction: ghrelin is a potent orexigenic agent in rodents and humans. Some studies have shown that ghrelin participates in the adaptive response to weight loss and plasma concentration of ghrelin rises with dieting. On the other hand, weight loss and fasting is accompanied by increased levels of epinephrine and cortisol. In this study, we investigated the effects of epinephrine and cortisol...
