(1959)Nervous accommodation of the sensitive elements of the pulp was determined in 152 teeth by measuring the accommodation index with 2 exponentially increasing currents -of different rise-times.Thirty-five teeth with pulpal ...
-
(Springer-Verlag, 1965)1. The effects on brain weight and histological appearance of adrenalectomy, of a stereotactic cerebral lesion and of sodium chloride in drinking water were studied in 120 rats. 2. Brain edema is measured by means of ...
-
(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 ...
-
(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 ...
-
(1976)The right and left basal artery have been measured in serial radiographs taken annually for 3 years or more, in 48 boys and 45 girls, all clinically normal. Centiles were constructed from 5 to 15 year old children. A study ...
-
(1977)The mechanism of the transient enhancement of the amplitude of the action potential (AAP) induced by harmaline (HME) was studied in rat atria. The results show that HME increases AAP through an enhancement of the slow ...
-
(1977)The effect of harmaline (HME) was analyzed in rat strips superfused in vitro. A dual inotropic action was found: the positive component was due to a transient catechol-mediated enhancement of the velocity of development ...
-
(1978)Protein digestion was studied in pair-fed rats receiving an adequate (protein 12% and alcohol 35% of calories) diet during 24 weeks. No differences in fecal nitrogen excretion were observed between the alcohol-treated and ...
-
(1978)The effects of a fat-supplemented diet and clofibrate (ethylchlorophenoxyisobutirate) upon serum lipids and liver catalase activity were studied in male rats. A butter-supplemented diet produced a striking increase of serum ...
-
(1979)Recent studies of the effects of hypoxia on human growth and adult size have focused mainly on the variability of single measurements. In this paper we explore changes with altitude and ethnicity (Spanish‐Aymara ancestry) ...
-
(1979)The location of ova in the genital tract was studied between 24 and 120 hours after the luteinizing hormone (LH) surge in 32 women who had been treated with methyl ergonovine in doses known to stimulate tubal contractility. ...
-
(1981)Rat isolated kidneys were perfused for 60 minutes with a modified Krebs-Henseleit bicarbonate solution. Perfusate and urine samples showed kininogenase activity (active kallikrein) which could be enhanced by activation ...
-
(1982)The gross morphology, histology, and ultrastructure of Liolaemus gravenhorsti gonads prior to and after differntiation are described. Special emphasis has been given to characterization and changes of the germ cell line ...
-
(1989)The leaching kinetics of a complex copper sulfide ore has been studied in laboratory-scale airlift percolators. Experiments were carried out to study the effect of a pure strain of Thiobacillus ferrooxidans on the dissolution ...
-
(1994)To assess the role of estradiol (E2) upon progesterone (P4) synthesis, a well defined human midluteal cell system was used. A dose-dependent inhibition of P4 synthesis with and without hCG was induced by E2. In addition, ...
-
(1995)In a placebo‐controlled double‐blind study, the therapeutic effect of Kan Jang tablets made from Andrographis paniculata (Barm. F.) (Ness) dried extract was tested in patients with common colds. The patients were divided ...
-
(1995)The prenatal development of the clavicular area was studied in two species: the domesticated sheep, which lacks a clavicle, and the cat, with a nonfunctional, rudimentary clavicle. A morphological and computerized morphometric ...
-
(1995)BACKGROUND: Liver cirrhosis is an important public health problem in Chile. AIM: To review the main epidemiological features of liver cirrhosis in Chile in the last 22 years. METHODS: Review of yearbooks of mortality and ...
-
(1996)Adult Sprague-Dawley rats were implanted with porous hydroxyapatite (Interpore 200®), following a procedure different from that of Kawaguchi et al. Instead of implanting hydroxyapatite (Ha) in periodontal osseus defects, ...
