(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)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)Drosophila discs-large (dlg) mutants exhibit multiple developmental abnormalities, including severe defects in neuronal differentiation and synaptic structure and function. These defects have been ascribed to the loss of ...
-
(Springer Verlag, 2003)While it is well established that highlanders have optimized their oxygen transport system, little is known about the acclimatization of those who move between different altitudes. The purpose of this study was to establish ...
-
(Elsevier Limited, 2003)Background: Depression in women is one of the commonest problems encountered in primary care. We aimed to compare the effectiveness of a stepped-care programme with usual care in primary-care management of depression in ...
-
(2002)Background: Short stature is the main feature of patients with Turner's syndrome. There is limited information regarding the spontaneous growth of these patients in Chile. Aim: To develop a specific growth chart for Chilean ...
-
(2003)Neuronal differentiation implies morphological and biochemical changes to generate a specialized neuron. N2A neuroblastoma cells can be promoted to undergo differentiation associated to neurites outgrowth, a process linked ...
-
(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 ...
-
(2003)Background: Although unreliability of periodontal measurements is considered mainly to concern attempts to detect true changes in longitudinal studies, it is also a source of variability that may substantially decrease the ...
-
(Biophysical Society, 2003)Fast Ca2+ release kinetics were measured in cardiac sarcoplasmic reticulum vesicles actively loaded with Ca2+. Release was induced in solutions containing 1.2 mM free ATP and variable free [Ca2+] and [Mg2+]. Release rate ...
-
(2003)The complex sequence of inductive events responsible for the generation of the neural crest at the border between the neural plate and the epidermis, triggers a genetic cascade involving several families of transcription ...
-
(Elsevier Ltd, 2003)Environmental pollution is a problem affecting many cities in our planet. Santiago de Chile is one with the worst indices. Because of that, local authorities implemented a few years ago an air quality monitoring network ...
-
(2003)Chronic administration of isoproterenol (IPR) results in a marked hypertrophy and in the induction of a group of putative proline-rich polypeptides in the mouse parotid glands. Some of these polypeptides (pps C-G) have ...
-
(2003)Objective. To study the consequences of low birth weight on glucose and lipid metabolism 48 hours after delivery. Methods. We studied 136 small for gestational age (SGA) and 34 appropriate for gestational age (AGA) term ...
-
(2003)Mesocestoides corti is a suitable model for studying cestode development because of its ability to reproduce asexually and segment in vitro. The cultured parasite is also capable of sexual differentiation and, probably, ...
-
(2003)OBJECTIVE: There is a seasonal variation in the incidence of diabetes mellitus and cardiovascular diseases. However, there is very little information about the seasonal variation in insulin sensitivity. We report the ...
-
(2003)Recent findings strongly support the hypothesis that diverse human disorders, including the most common neurodegenerative diseases, arise from misfolding and aggregation of an underlying protein. Despite the good evidence ...
-
(2003)Unlike eutherian males, pairing of the sex chromosomes in marsupial males during the first meiotic prophase is not mediated by a synaptonemal complex. Instead, a specific structure, the dense plate, develops during pachytene ...
