-
(1990)The exposure of drugs to light produces photodecomposition processes in several cases: the drugs undergo important chemical changes with a parallel change in their activities or potencies and generally with a loss of their ...
-
(Kluwer Academic Publishers, 1990)Spatial heterogeneity of the Rapel reservoir surface waters is analyzed through Landsat images. The image digital counts are used with the aim or developing an aprioristic quantitative sample design.Natural horizontal ...
-
(2000)Protein phosphatases are involved in many cellular processes. One of the most abundant and best studied members of this class is protein phosphatase type-2A (PP2A). In this study, PP2A was purified from the mussel Mytilus ...
-
(1990)The electrochemical reduction of 7-nitro-1,4-benzodiazepin-2-ones and of their acid hydrolysis products, 2-amino-5-nitrobenzophenones, was studied by polarography and cyclic voltammetry in a solvent - buffer system containing ...
-
(1990)Reorganization of the fertilized egg during completion of the first meiotic division was studied in the glossiphoniid leech Theromyzon rude. Rotation of the meiotic spindle, presumably as a result of changes in the length ...
-
(1989)This note presents measurements of the electric charge in a Nuclepore filter attained with a simple device able to detect induced charge in a metallic plate which is registered through a 610B KEITHLEY electrometer. A ...
-
(1990)The effect of ethyl alcohol ingestion on erythromycin kinetics was studied. Nine healthy volunteers, four males and five females, participated in the study. They received, in two separate occasions, 500 mg of erythromycin ...
-
(1989)1. The in vivo effect of estradiol and domperidone (a hypophysis stimulator of prolactin secretion) in immature ovariectomized-adrenalectomized and hypophysectomized rat mammary gland was studied. 2. γ-Glutamyltranspeptidase ...

-
(1990)Nitrendipine produces a well-defined polarographic peak due to the four-electron reduction of the nitro group. This peak is used for tracking the photodecomposition of nitrendipine in both UV light and daylight conditions. ...

-
(1989)The changes in the acquisition of conditioned avoidance responses (CARs) and the performance of some spontaneous behaviors were examined across the estrous cycle of female rats. CARs were facilitated during diestrus, ...
-
(1989)1. The cardiovascular effects of CLX were studied. 2. CLX induced hypotension, bradycardia, negative chronotropism and negative inotropism. 3. Electrophysiological studies showed a decrease of sinus venosus discharge ...
-
(1989)1. The analgesic effect of C1X, nifedipine, metamizol, indoprofen and morphine in the pain induced by formalin injection (formalin test) was studied. 2. Attempts to demonstrate tolerance to C1X were unsuccessful. 3. In the ...
-
(1989)Abstract The quenching of the benzophenone triplet by lysozyme and its constituent amino acids in aqueous solutions have been studied. Native lysozyme quenches the benzophenone triplet with a high rate constant, 4 × ...
-
(1960)Two crystalline forms of bis-(5-aminotetrazolato)-copper (II) have been prepared and characterized. Visible and ultraviolet spectra of aqueous copper (II)-5-aminotetrazole solution have been examined. Continuous variation ...
-
(1989)Patients with chronic renal failure (CRF) are continuously exposed to hyperkalemia. In these patients the extrarenal disposal of a potassium load may be very important to determine the plasma potassium levels. We studied ...
-
(1989)Norepinephrine levels and tyrosine hydroxylase and dopamine-beta-hydroxylase activities have been used to evaluate the effect of castration and testosterone treatment on the sympathetic innervation of the adult vas deferens. ...
