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 ...

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 ...
-
(Lippincott Williams & Wilkins, 2017)The purinergic P2X2 receptor (P2X2R) is an adenosine triphosphate-gated ion channel widely expressed in the nervous system. Here, we identified a putative cyclin-dependent kinase 5 (Cdk5) phosphorylation site in the full-size ...
-
(Elsevier Science Ltd., 1995-01-16)Bioactivity guided fractionation of the dichloromethane extract from Psoralea glandulosa yielded the isolation of a diasteromeric mixture of cyc1obakuchiols A and B as possible anti-inflammatory active compounds.
-
(Springer, 2015)The preparation and structural elucidation of the 2 alpha-cyclodextrin/decylamine inclusion compound (IC) by proton nuclear magnetic resonance, rotating frame overhauser effect spectroscopy and powder X-ray diffraction ...
-
(MDPI, 2021)This article describes the synthesis and characterization of beta-cyclodextrin-based nano-sponges (NS) inclusion compounds (IC) with the anti-tumor drugs melphalan (MPH) and cytoxan (CYT), and the addition of gold nanoparticles ...
-
(Pergamon Press, 1974-02-20)The known alkaloids zizyphine-A (1) and -B (2), abyssinine-A (4) and -B (5), and the previously undescribed zizyphine-C (3), -D (6) and -E (7) have been isolated from the stem bark of Zizyphus oenoplia. The structures ...

-
(ELSEVIER, 2003-11)The mode of action of cyclosporine (CsA) has been ascribed to its capacity to inhibit IL-2 and IFNgamma production by T cells, two cytokines implicated in allograft rejection. Recently, it has been reported that upon ...
-
(Asociación Interciencia, 2016)Cypermethrin is a synthetic pyrethroid widely used as an agropesticide. The aim of this study was to determine the effect of cypermethrin on reproductive patterns of the planarian Dugesia gonocephala, a bioindicator ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2009-04-15)The CSRNP (cystein-serine-rich nuclear protein) family has been conserved from Drosophila to human. Although knockout mice for each of the mammalian proteins have been generated, their function during vertebrate development ...
