(2013)Temperate Australia sits between the heat engine of the tropics and the cold Southern Ocean, encompassing a range of rainfall regimes and falling under the influence of different climatic drivers. Despite this heterogeneity, ...
-
(2012)The significance and cause of the decline in biomass burning across the Americas after ad 1500 is a topic of considerable debate. We synthesized charcoal records (a proxy for biomass burning) from the Americas and from ...
-
(Sociedad de Biología de Chile, 2013)Pouteria splendens (lúcumo chileno, palo colorado) es un árbol endémico de Chile central con problemas de conservación. Es la única especie representante de la familia Sapotaceae en el país y se conoce muy poco de su ciclo ...
-
(Sociedad de Biología de Chile, 2013)Se identifi có y analizó la osteofauna aviar del sitio arqueológico Copaca 1, ubicado en el litoral árido de la segunda Región de Chile. La muestra estuvo compuesta por 685 fragmentos extraídos desde nueve capas con ...
-
(2013-09)Sonic Hedgehog (Shh/GLI) and EGFR signaling pathways modulate Neural Stem Cell (NSC) proliferation. How these signals cooperate is therefore critical for understanding normal brain development and function. Here we report ...
-
(Elsevier, 2013)Here we set out to evaluate the role of hexokinase and glycogen synthase in the control of glycogen synthesis in vivo. We used metabolic control analysis (MCA) to determine the flux control coefficient for each of the ...
-
(Society for Conservation Biology, 2013)La Convención sobre Diversidad Biológica (CDB) espera que las plantaciones forestales contribuyan a la conservación de la biodiversidad. Un sotobosque bien desarrollado en plantaciones forestales puede servir como hábitat ...
-
(John Wiley & Sons, 2013)Quaternary glaciations in Antarctica drastically modified geographical ranges and population sizes of marine benthic invertebrates and thus affected the amount and distribution of intraspecific genetic variation. Here, ...

(Elsevier, 2013)Hydrophobically modified amphiphilic polyelectrolyte films derived from poly (maleic anhydride-altstyrene) containing hydrophobic aryl-alkyl type side chains such as phenyl-ethyl, phenyl-butyl, naphthyl-ethyl and ...
-
(American Chemical Society, 2006-06-26)Photochemical reaction of (eta(5)-C5R5)Re(CO)3 (R = H, Me) with pentachlorobenzene (lambda = 350 nm, hexane solution) yields trans-(eta(5)-C5R5)Re(CO)(2)(2,3,4,5-C6HCl4) (trans-1, R = Me; 2, R = H) formed by insertion of ...
-
(American Chemical Society, 1999-02)Reaction of Cp*Re(CO)(2)I-2 with methylcopper affords cis-Cp*Re(CO)(2)(Me)I, which converts to the trans isomer on prolonged reaction or in the presence of neutral alumina. The X-ray structure of the trans isomer has been ...
-
(Elsevier, 2013)Cyclotriphosphazene is used as a sacrificial solid-state template to synthesize a range of Ag and Pd nanoparticles with diverse geometries by thermal treatment using MLn/N3P3(O2C12H8)3 mixtures. The Pd and Ag nanoparticles ...
-
(1999)Reproductive variables from 1529 females and 168 males of Atlantic salmon Salmo salar L. 1758 were recorded individually during the 1995 spawning season at a salmon farm in the south of Chile. The spawning period occurred ...
-
(WILEY-BLACKWELL PUBLISHING, INC,, 2008-11)The blood of 21 adult South American mouse opossums (Thylamys elegans) captured from April through August of 2005 in central Chile was examined for parasites. Light microscopic analysis of blood smears initially suggested ...
-
(WILEY-BLACKWELL PUBLISHING, INC,, 2009-11)The Microbiotheriid Dromiciops gliroides, also known as ‘Monito del Monte’, is considered to be a threatened species and the only living representative of this group of South American marsupials. During the last few ...
-
(Elsevier, 2013)tIn mammals, adaptation to chronic hypoxia requires the integrity of the arterial chemoreceptors, speciallythe carotid body (CB). Chronic hypoxia increases the sensibility of the CB by acting on the receptorcells, but there ...

Peroxisome Proliferator-activated Receptors and Alzheimer's Disease: Hitting the Blood–Brain Barrier (Springer, 2013)The blood–brain barrier (BBB) is often affected in several neurodegenerative disorders, such as Alzheimer's disease (AD). Integrity and proper functionality of the neurovascular unit are recognized to be critical for ...
