(1998)Interactions involving the T-cell receptor (TCR) and major histocompatibility complex (MHC) are fundamental to the generation of a specific immune response. The study of interpopulation differences in TCR genes may identify ...

(2002)Woman of 39 years of age from Talca province (VII Region) who presented intense abdominal pain which was interpreted as an acute abdomen, and an exploratory laparotomy was performed, wich was not concludent. After different ...
-
(1998)HTLV-1 (human T-cell leukemia virus type I) associated myelopathy (HAM) is a demyelinating disease. We showed that the CSF of patients and heated CSF of normal subjects induced a segmentary demyelination in rat nerves, and ...
-
(University of Chicago Press, 1998)The adaptive modulation hypothesis posits that the expression of digestive proteins should be modulated in response to intake of their respective substrates. A corollary of this hypothesis suggests that dietary flexibility ...
-
(1993)This study sought to estimate for the first time the prevalence of fascioliasis among the rural population in the Chilean provinces of Curico, Talca, and Linares, while also determining the disease's prevalence among horses ...
-
(1998)Among collections of Triatoma spinolai from various sites in northern Chile, adults from coastal populations are invariably wingless, whereas inland populations show balanced alary polymorphism between wingless females and ...
-
(American Society of Tropical Medicine and Hygiene, 1998)An antibody-dependent, complement-mediated lysis test performed with three Chilean trypomastigote strains used as target cells revealed strain dependence in the detection of lytic antibodies in chronic chagasic sera. The ...
-
(1997)The access to information is crucial to plan, define and evaluate nutritional interventions. Analyzing the main nutritional indices proposed by international fora for food and nutrition surveillance, the usefulness of ...
-
(1997)The modulational instability of a linearly polarized, strong, electromagnetic wave in a (unmagnetized) positron-electron plasma is analyzed using relativistic two-fluid hydrodynamics to properly account for physical regimes ...
-
(1997)We study the parametric decays of a large amplitude, linearly polarized electromagnetic wave in an electron-positron plasma. We include harmonic generation, the ponderomotive force, and weakly relativistic effects. It is ...
-
(Universidade de Sao Paulo, 1997)Only three cases of human infection by anisakid nematodes have been reported in Chile since 1976. In the present case, an anisakid worm, identified as a fourth-stage Pseudoterranova decipiens larva, was removed with a ...
-
(1976)The Cotton effect of dd transitions of copper(II) complexes with optically active aminoacids in aqueous media is qualitatively analyzed in terms of conformational models by means of a simple one-electron MO treatment. The ...
-
(1997)Background: Chilean girls of middle and low socioeconomic levels are shorter than their European or North American counterparts. Aim: To challenge the hypothesis that undernutrition is the cause of the shorter stature of ...
-
(Endocrine Society, 1997)To study the effect of delaying epiphyseal fusion on the growth of GH- deficient children, we studied 14 pubertal, treatment naive. GH-deficient patients (6 girls and 8 boys) in a prospective, randomized, placebo- controlled ...
-
(1996)BACKGROUND: The application of a simple fluorometric analytical method enabled us to quantify the urinary porphyrin excretion and to establish the prevalence of porphyria cutanea tarda (PCT) in the town of Madrid, Spain, ...
