(SOC BIOLGIA CHILE, 2010-08-12)One of the mechanisms for generation of tolerance involves immature dendritic cells (DCs) and a subpopulation of regulatory CD4+ CD25+ T lymphocytes (TREG). The purpose of this work was to analyze how Cyclosporine A (CsA), ...
-
(AMER GEOPHYSICAL UNION, 2010-09-30)The key objective of this paper is to develop a 1‐D hydrodynamic and sediment transport model, namely, RILL1D, that handles transcritical flows over abrupt changes (e.g., formation of pool crests and width change) in a ...
-
(AMER SOC CELL BIOLOGY, 2010-08-09)Cultured neurons obtained from MAP1B-deficient mice have a delay in axon outgrowth and a reduced rate of axonal elongation compared with neurons from wild-type mice. Here we show that MAP1B deficiency results in a ...
-
(WILEY-BLACKWELL, 2010-06-22)We study the effect of the non-linear process of ambipolar diffusion (joint transport of magnetic flux and charged particles relative to neutral particles) on the long-term behaviour of a non-uniform magnetic field in a ...
-
(AMER PHYSICAL SOC, 2010-09-23)The resistivity of metallic structures depends on both electron-grain boundary scattering and electron-surface scattering. By tuning the grain size, we have been able to separate the contribution to the resistivity ...
-
(SOC CHILENA QUIMICA, 2010-07-12)We present here the results of a Density Functional Theory study of the relationships between electronic structure and peripheral benzodiazepine receptor affinity for a group of N,N-dialkyl-2-phenylindol-3-ylglyoxylamide ...
-
(WILEY-BLACKWELL, 2010-11)Aim To reconstruct the Late Glacial and Holocene vegetation history of western Tasmania and to test the long-held notion of a replacement of forest by moorland during the mid to late Holocene in western Tasmania, ...
-
(ELSEVIER SCIENCE, 2010-08-13)This work describes the preparation of a new tetraruthenated porphyrin and the corresponding polymeric film. This macromolecule consists of a Ni(II) tetrapyridylporphyrin coordinated to four [Ru(5- NO2-phen)2Cl]+ moieties. ...

An efficient method to find potentially universal population genetic markers, applied to metazoans (BIOMED CENTRAL LTD, 2010-09-13)Background: Despite the impressive growth of sequence databases, the limited availability of nuclear markers that are sufficiently polymorphic for population genetics and phylogeography and applicable across various ...
-
(MICROBIOLOGICAL SOCIETY KOREA, KOREA SCIENCE & TECHNOLOGY CENTER, 2010-08-22)In this study, the existence of intra-specific and inter-generic fungicidal activity in Xanthophyllomyces dendrorhous and Phaffia rhodozyma strains isolated from different regions of the earth was examined. Assays were ...
-
(PALEONTOLOGICAL SOC INC, 2010-05-25)This study presents the first record of Eocene birds from the western margin of southernmost South America. Three localities in Magallanes, southern Chile, have yielded a total of eleven bird remains, including Sphenisciformes ...
-
(SOC CHILENA QUIMICA, 2010-08-18)Seven pigments of patrimonial interest for the Chilean artwork were analyzed by means of Raman spectroscopy by using the 632.8 nm excitation laser line. Samples were supplied by the National Center of Conservation and ...
-
(OXFORD UNIV PRESS INC, 2010-08-06)Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is revealing the adaptive significance of personalities, although the mechanisms driving ...

-
(WILEY-BLACKWELL, 2010-09-13)Species coexistence within ecosystems and the stability of patterns of temporal changes in population sizes are central topics in ecological theory. In the last decade, adaptive behaviour has been proposed as a mechanism ...
-
(BIOMED CENTRAL LTD, 2010-11-03)Background: Iron is essential for the maintenance of basic cellular processes. In the regulation of its cellular levels, ferritin acts as the main intracellular iron storage protein. In this work we present a mathematical ...
-
(AMER ASSOC ADVANCEMENT SCIENCE, 2010-10-26)Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world’s vertebrates. One-fifth of species are classified as Threatened, ...
-
(ELSEVIER SCIENCE INC, 2010-12-15)The existence and global exponential stability of an almost periodic solution of an impulsive neural network model with distributed delays is considered in a matrix setting. The approach transforms the original network ...
