(1997)Background: Trauma in the third cause of death in Chile and the most important among youngsters. Aim: To analyze the certification of deaths by trauma, studying those deaths in which it is not known if they were accidental ...
-
(Society of Biology of Chile, 2005)The specific signaling connections between the mitogen-activated protein kinases (MAPK) such as c-Jun N-terminal kinase (JNK-1) and phosphatases PP4 and M3/6, affecting the family of early nuclear factors, is complex and ...

(2005)The description of a new species of Eupsophus, from Los Queules National Reserve (35° 59' S, 72° 41'W) adds a new endemic taxon to the fauna of telmatobines (Amphibia, Leptodactylidae) of Chile, and extends the geographical ...
-
(2002)It is well known that in patients with Barrett's esophagus (BE), even after antireflux surgery, intestinal metaplasia can progress to dysplasia or even adenocarcinoma. However, the opposite - that is regression of dysplastic ...

(2003)Aim: To observe the acute effect of the organophosphorous insecticide malathion on testicular function in mice. Methods: The effects of a single dose of malathion [240 mg/kg (1/12 LD 50)] on plasma acetylcholinesterase ...
-
(Biophysical Society, 2003)Olfactory receptor neurons (ORNs) respond to odorants with characteristic patterns of action potentials that are relevant for odor coding. Prolonged odorant exposures revealed three populations of dissociated toad ORNs, ...
-
(2003)By modifying the degree of hydrogenation of dietary fat, it is possible to modify the fatty acid composition and the biochemical activity of cellular tissues. The age can be another variable influencing these modifications. ...
-
(2003)The Du Noüy method has been employed to study the interfacial properties of poly(4-vinylpyridine) N-n-alkyl quaternized with hexyl, octyl and decyl bromide, at the chloroform/water interface. The interfacial tension is ...
-
(2003)Despite important advances in the under-standing of copper secretion and excretion, the molecular components of intestinal copper absorption remain a mys-tery. DMT1, also known as Nramp2 and DCT1, is the trans-porter ...
-
(2002)Objective: To investigate the role of nitric oxide (NO) and death regulatory genes, bcl-2 and bax, in human endometria apoptosis.Design: Expression of bcl-2, bax, NO synthases (NOS), and the apoptotic effect of L-arginine ...
-
(2002)Background: Strongyloides stercoralis is a world wide distributed small intestinal nematode parasite. In immunocompetent individuals S stercoralis can produce asymptomatic infections or a moderate clinical picture of ...
-
(2002)Clomiphene can be used to treat anovulation due to hypothalamus or pituitary gland dysfunction, and it normalizes the luteal phase in stimulated patients. It can be used to estimate ovarian follicle reserve, and may be ...
-
(2003)We present two cases of nosocomial urinary tract infection due to Trichosporon asahii in intensive care unit patients with bladder catheter from two hospitals in Santiago, Chile. Both patients had an several catheters and ...
-
(Society for the Study of Amphibians and Reptiles, 2003)Genetic divergence between two traditionally recognized subspecies, Liolaemus monticola chillanensis and Liolaemus monticola ssp, was assessed by allozymic comparison. Both morphotypes are syntopic and restricted to the ...
-
(2003)1 We have investigated the effects of loperamide on intracellular Ca2+ stores and membrane K+ channels in insulin-secreting hamster insulinoma (HIT-T15) cells. 2 In cell-attached patch-clamp mode, loperamide (3 – 250 mM) ...
-
(2003)This study was designed 1) to assess corpus luteum (CL) steroidogenesis in response to exogenous human chorionic gonadotropin (hCG) at different times during the luteal phase, 2) to examine the effect of hCG on steroidogenic ...
-
(2003)Background: Genes for dopamine receptor DRD4 and dopamine transporter DAT1 are highly polymorphic. Two alleles of these genes, namely the DRD4.7 and the DAT1*9 are frequently associated to the attention deficit disorder ...
-
(Sociedad de Biologia de Chile, 2003)Univariate and multivariate statistical analyses of 28 meristic characters recorded for 19 samples of the lizard Liolaemus monticola monticola were used to compare geographical variation in morphology with chromosomal races ...
-
(2003)This randomized pilot study was designed to determine whether the addition of interferon α-2b to standard radiation therapy offered an advantage in loco-regional control and survival over radiation therapy alone in a ...
-
(Elsevier Ireland Ltd, 2003)Cytokines produced by spinal cord glia after peripheral inflammation, infection or trauma have a relevant role in the maintenance of pain states. The effect of intrathecally administered interleukin-1β (IL-1β) on spinal ...
