(1998)Adenosine 5'-cyclic diphosphoribose [cyclic ADP-ribose (cADPR)], a metabolite of NAD+ that promotes Ca2+ release from sea urchin egg homogenates and microsomal fractions, has been proposed to act as an endogenous agonist ...
-
Cyclic AMP cascade mediates the inhibitory odor response of isolated toad olfactory receptor neurons (AMER PHYSIOLOGICAL, 2005-09)Odor stimulation may excite or inhibit olfactory receptor neurons (ORNs). It is well established that the excitatory response involves a cyclic AMP (cAMP) transduction mechanism that activates a nonselective cationic cyclic ...

(Wiley-Liss, Inc., 2003-07-04)Mouse-transformed keratinocytes cultured in the presence of transforming growth factor 1 (TGF- 1) acquire an array of morphologic and functional properties that give rise to a migratory phenotype that expresses mesenchymal ...
-
(Academic Press, 1996)The role of cyclic AMP-dependent protein kinase (PKA) and systolic function during the development of left ventricular hypertrophy (LVH) still remain uncertain. The aim of this work is to study PKA activity and mechanical ...
-
(2016)The paper examines the effect of the presence of small percentages (1-5%) by dry mass of the sand of laponite - a synthetic nanoclay with plasticity index exceeding 1000% - on the cyclic response of sand with relative ...
-
(Elsevier, 2018)The level of existing research, as well as current code provisions and modeling approaches, are not adequate to characterize the behavior of squat reinforced concrete walls with shear - controlled responses. In this study, ...

(PROFESSOR D A SPANDIDOS, 2008-06)A cyclic peptide derived from the active domain of α-fetoprotein (AFP) significantly inhibited the proliferation of MCF7 cells stimulated with the epidermal growth factor (EGF) or estradiol (E2). The action of these ...
-
(MDPI, 2020)This paper presents a numerical study on the seismic performance of end-plate moment connection between I-beam to HSS (hollow structural section) column stiffened by outer diaphragms (EP-HSS). In previous experimental ...

Cyclic voltammetric and EPR spectroscopic studies of benzodiazepines: Loprazolam and flunitrazepam (Elsevier, 1997)The present paper reports on the electrochemical characterization by cyclic voltammetry of two 1,4-benzodiazepines, loprazolam and flunitrazepam in protic, aprotic and mixed media. In protic media (ethanol + 15 mM citrate ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2001-09)The electro-oxidation of methanol at Pt-Ir and Pt deposits, and at Pt, Ir, and Pt-Ir wires in sulfuric acid solution was studied by cyclic voltammetry (CV), and in the case of Pt-Ir and Pt electrodeposits, also with the ...
-
(AMER CHEMICAL SOC, 2003-04-15)Potassium ferricyanide ([Fe(CN)(6)](3-)) reduction and ferrocenemethanol (Fe-OH) oxidation at a beta-cyclodextrin (beta-CD)-modified gold electrode were investigated by cyclic voltammetry (CV) and scanning electrochemical ...

(2003)Potassium ferricyanide (Fe(CN)6]3-) reduction and ferrocenemethanol (Fc-OH) oxidation at a β-cyclodextrin (β-CD)-modified gold electrode were investigated by cyclic voltammetry (CV) and scanning electrochemical microscopy ...
-
(ELSEVIER SCIENCE, 2002-02-08)We have studied the O-2/O-2(.-) redox couple on the HMDE in DMSO aprotic media, obtaining optimal conditions of both oxygen concentration and scan rate in order to avoid oscillatory phenomena. By choosing the oxygen ...

Cyclic voltammetric study of the nitro radical anion from nitrendipine generated electrochemically (1991)Electrochemical studies on nitrendipine using mixed aqueous/dimethylformamide (DMF) solvent have allowed us to generate the one-electron reduction product, the nitro radical anion, RNO.-2. The voltammetric technique has ...
