-
(1982)Enzymatic hydrolysis of skim milk lactose and proteins was investigated in a batch reactor; the final aim is to produce a predigested dietary product. The use of yeast β‐galactosidase, a vegetable protease, a fungal protease, ...
-
(1982)Two homogeneous isoenzymes of apyrase from Pimpernel and Desirée varieties of Solanum tuberosum were obtained by affinity chromatography on agarose-Cibacron Blue or agarose-ATP-phosphonate columns. Both enzymes split POP ...
-
(1982)The pharmacokinetics of amoxicillin was investigated in 4 healthy volunteers and in 16 patients with varying degrees of renal impairment, 4 of whom were on regular hemodialysis. Amoxicillin was administered both in a 1-g ...
-
(1982)The electroactivity of a degradation product from penicillin V is described.This electroactive product is formed by acidic hydrolysis at pH 4.0 and heating at 90QC for 60 minutes. This derivative has not been identified, ...
-
(Universidad de Santiago de Chile. Dirección de Investigaciones Científicas y Tecnológicas, 1983)Se estudia el comportamiento polarográfico de pesticidas organofosforados (Paratión y Dimetoato) y de pesticidas organoclorados (DDt, Aldrín y Dieldrin), estableciéndose para cada uno de ellos las condiciones óptimas de ...
-
(Kluwer Academic Publishers, 1983)Based on a similarity ring constructed from a substitution probability matrix, we have analyzed the conservation of some amino acid properties in the evolution of proteins. Refractive index and bulkiness are highly conserved, ...
-
(1983)2-Hydroxy-3-(p-hydroxyphenyl)-6-methylpyrazine (HHMP) is identified as the product obtained by acidic degradation of amoxycillin in the presence of formaldehyde. I.R., n.m.r. and elemental analysis data are reported. The ...
-
(Springer-Verlag, 1983)The perception of the surrounding environment and use of the flora by the inhabitants of Toconce, a Pre-Altiplanic community in the Andes of northern Chile, were investigated. Six ecological units, which are given the local ...
-
(1983)The interaction of glutathione with ampicillin was investigated by a new a.c. polarographic procedure. Ampicillin was found to interact strongly with glutathione. The stability constants were ascertained from the polarographic ...
-
(1983)The a.c polarographic method has been applied in the study of the glutathione-ampicillin interaction at pH 7.4 and 37°C. Ampicillin shifted the peak potentials of glutathione to less negative values. A linear relation was ...
-
(1983)The photochemistry of several phenyl alkyl and p-anisyl alkyl ketones has been examined using laser flash photolysis and conventional quantum yield techniques. The methoxy-substituted ketones show higher activation energies ...
-
(1983)1. 1. Prazosin, haloperidol, propranolol or timolol had no effect on the electrically evoked muscular twitch. 2. 2. Atropine was able to antagonize competitively acetylcholine (pA2 = 9.29 ± 0.30). 3. 3. The muscular twitch ...
-
(1983)Kainate (0.62-5 mM) was found to increase the initial rate of influx of 45Ca and of 22Na into the non-inulin space of rat thin brain cortex slices incubated in vitro, and to shorten the equilibration time for both these ...
-
(1983)The effects of angiotensin II on efflux of radiocalcium and production of aldosterone from dispersed bovine adrenal glomerulosa cells were studied using a flow-through system. Concentrations of angiotensin II between 1.25 ...
-
(1983)A simple and rapid method for the multielement routine analysis of atmospheric particulate matter is described. The samples collected on four different types of filters were treated with HNO3 and HCl at 110-120 °C in pyrex ...
-
(1983)Exposure of Xenopus laevis oocytes to temperatures above 31° causes a drastic decrease in protein synthesis and a relative increase of a heat shock protein (HSP) of approximate molecular weight of 68,000. A significant ...
-
(1983)As part of study of Chagasic cardiopathy in Chile we report a follow-up study of 100 cardiopathic patients from two endemic areas who had been diagnosed 4 years earlier during an epidemiological and clinical survey. The ...
