(1967)It is possible to detect microscopically dezincification in artificial sea water at 50°C of hard or recrystallized 63/37 two phase (α + β) and single phase (α) brass samples, after simple immersion or after exposure in ...
-
(1967)Four isoenzymes of adenosine triphosphate (ATP):d-hexose 6-phosphotransferase have been separated from rat liver by DEAE-cellulose. Three of these isoenzymes (A-C) are similar to animal hexokinases inasmuch as they exhibit ...

(Universidad de Chile, Facultad de Artes, Departamento de Música, 1967-06)
-
(1968)Two distinct fiber systems are recognizable in the dorsal lateral geniculate nucleus of the rat. One consists of small bundles running in a transverse plane from the ventrolateral to the dorsomedial parts of the nucleus, ...
-
(1968)Cytotoxic agents, cadmium, iodoacetate, thio-TEPA, podophyllin, colchicine, and alcohol, were instilled in one uterine horn of the rat to observe their subsequent effect on fertility. Cadmium and iodoacetate interfere with ...
-
(1968)The frequency of Carabelli's cusp (27.24%) and shovel‐shaped incisors (45.72%) were determined in a sample of students from the city of Valparaíso. These values are intermediate between those found in Caucasian and Mongolian ...
-
(1968)1. The quality of the protein in five high-protein mixtures intended for human consumption and made from materials that are available in Chile is reported. 2. The ingredients were fish flour, bread, wheat (Triticum sativum ...
-
(1968)Labelled Ca `,+ were incorporated into giant axons froln the squid Dosidicus gigas by immersing them in sea water containing 4'5Ca'-' ~. The washout technique was used and two kinetics for 4SCa2+ outflow were demonstrated ...
-
(1969)Extract: These studies were designed to define alterations in erythropoiesis that resulted from prolonged and controlled caloric deprivation. The caloric deprivation in the animal model chosen simulated that experienced ...
-
(1969)Using autoradiographic technique the migratory movements of cells destined to form the anterior thalamic nuclear group and the limbic cortex were studied in 54 embryos or newborn rabbits the mothers of which were injected ...
-
(1969)The previous administration of chloroquine to normal rats resulted in a significant increase in the lethal dose of morphine and in a higher amount of conjugated morphine in the liver. No differences were found on normorphine ...
-
(1969)The evolution of DC cortical shifts during learning, as well as its association with behavioral responses, were studied in thirteen rabbits using unpolarizable electrodes chronically implanted. The animals were trained to ...
-
(1969)Extract: In ten ‘normal’ brains, obtained from well-nourished Chilean children who died accidentally, weight, protein, and DNA and RNA content were all normal when compared with those values derived from similar children ...
-
(1969)It is shown that mixing among SU(3) supermultiplets leads to new mass relations. These mass relations could be useful for the interpretation of some experiments and for further particle assignments to SU(3) supermultiplets. ...
-
(1969)Pregnant and non-pregnant rats fed on casein diets of different protein value during 20 days were used to study the effect of the protein value of the diet on the apparent Net Protein Utilization and for re-evaluating ...
-
(1969)The main purpose of this work has been to study further the association of cations and anions with cell membrane lipids, in particular with phosphatidylcholine. The adsorption of Ca2+ or SO4 2- to phosphatidylcholine ...
-
(1969)Nine color blind subjects were discovered in a survey of 140 Aymaras of Arica, Chile, using as screening test a portable Anomaloscope, Ishihara tables and Hardy‐Rand‐Ritter plates. Pseudosisochromatic test failed on detecting ...
-
(1970)Large doses of estrogens have been used by several investigators as "emergency" postcoital contraceptives but their true effectiveness in the human is not known. We report here the results of the use of quingestanol acetate, ...
