-
(1997)In toad olfactory neurons, a putrid odorant mixture inducing inhibitory responses increases Ca2+-activated K+ conductance, developing a hyperpolarizing receptor potential. Removal of extracellular Ca2+ or exposure to ...
-
(Blackwell Publishing, 1997)Intrahepatic cholestasis of pregnancy is characterized by skin pruritus and a biochemical cholestasis of mild to moderate severity appearing during pregnancy (mainly in the third trimester) and disappearing after delivery. ...
-
(Wiley-VCH Verlag, 1996)Grafting of polypropylene was carried out in both boiling xylene and decalin as solvent medium with itaconic acid (2-methylenesuccinic acid) as functional polar monomer using 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane ...
-
(1992)A protein isolated and purified from the outer membrane of the acidophilic, chemolithotrophic bacterium, Thiobacillus ferrooxidans with an oligomeric molecular weight of 90 000 Da (p9O) was incorporated into phosphatidyl ...
-
(1997)Chilean folklore medicine uses Trevoa trinervis Miers. (Rhamnaceae), 'trevo', for the treatment of inflammation caused by wounds and burns. The antiinflammatory and antipyretic activities of crude methanol, aqueous and ...
-
(Elsevier Ireland Ltd, 1996)Progressive spastic paraparesis (PSP) is a demyelinating disease of the central nervous system. We studied the ability of the cerebrospinal fluid (CSF) of patients to induce alterations in rat peroneal nerves, and to modify ...
-
(Elsevier, 1997)The electrochemical reduction of three nitrotetralone derivatives by tast and differential pulse polarography and cyclic voltammetry in a wide pH range was studied. In aqueous media, the reduction of mono- and dinitrotetralone ...
-
(Elsevier Ltd, 1997)Electrochemical studies on 4-(nitrophenyl) substituted 1,4-dihydropyridines of pharmacological importance have allowed us to generate the one-electron reduction product, the nitro radical anion, ArNȮ- 2 , in aprotic media. ...
-
(Elsevier Ireland Ltd, 1996)The reactivity of the electrochemically generated nitro radical anion from nifedipine, a nitro aryl 1,4-dihydropyridine derivative, with relevant endobiotics and thiol-containing xenobiotics, was quantitatively assessed ...
-
(Taylor and Francis Inc., 1997)Ketorolac is an antiinflammatory-analgesic agent that is oxidizable at the glassy carbon electrode. The voltammetric oxidation produces two well resolved pH-dependent peaks, that are overlapped at pH>10. Using this ...
-
(1997)Acaena splendens H. et A., Rosacene, has been used in Chilean traditional medicine for the treatment of fever and inflammation. The antipyretic and antiinflammatory properties of the infusion, methanol, petroleum ether and ...
-
(Elsevier Ireland Ltd, 1996)The electrochemical properties of nifuroxazide have been investigated in aqueous and aqueous-DMF mixed solvents. In aqueous media, a single, irreversible four-electron reduction occurs to give the hydroxylamine derivative. ...
-
(1996)The aim of the present study was to differentiate two modalities of intrinsic time scales : i- the geometric or Euclidean modality, which is based on the constant speed of mass transport or of wave transmission in cylindrical ...
-
(1996)The result obtained from different studies of the chronopharmacokinetics of some controlled-release tablets of theophylline are variable, since some authors report differences while others do not. At our laboratory we have ...
-
(Elsevier Ltd, 1996)The conformation in 2H2O of 4-thio-L-lyxono-1,4-lactone (1) was studied by nuclear magnetic resonance spectroscopy, by means of homonuclear (J(1(H),1(H))) and heteronuclear (J(1(H),13(C))) coupling constants. The couplings ...
-
(Society for the Study of Reproduction, 1996)The mammalian testis is innervated by extrinsic catecholaminergic nerves and responds to catecholamines with steroid secretion. Although the primate testis has also been shown to be innervated, potential differences in the ...
-
(Elsevier B.V., 1996)Loratadine, a potent antihistamine drug, is not directly electroreducible at a dropping mercury electrode; however, by means of a nitration procedure it is possible to obtain a nitro-loratadine derivative which has been ...
-
(1996)The antipyretic and antiinflammatory properties of the infusions and methanol extracts of the whole plant of Cuscuta chilensis Ker-Gawl. and of the aerial parts of Cestrum parqui L'Herit. and Psoralea glandulosa L. were ...
-
(Elsevier Ltd, 1996)A process of recovery of copper from acid leach residual solution with 5-dodecylsalicylaldoxime dissolved in n-hexane was carried out at 30°C in a countercurrent tubular membrane extractor using a hollow fiber as solid ...
-
(1995)The objectives of this work were to establish the utility of chitosan of Chilean production, as an excipient suitable for producing a prolonged-release hydrophilic matrix, and to compare two matrix systems, one with chitosan ...
