(PERGAMON-ELSEVIER SCIENCE, 2005-06)Gibberella fujikuroi is a species-rich monophyletic complex of at least nine sexually fertile biological species (mating populations, MP-A to MP-I) and more than 30 anamorphs in the genus Fusarium. They produce a variety ...

Cyclic AMP cascade mediates the inhibitory odor response of isolated toad olfactory receptor neurons (AMER PHYSIOLOGICAL, 2005-09)Odor stimulation may excite or inhibit olfactory receptor neurons (ORNs). It is well established that the excitatory response involves a cyclic AMP (cAMP) transduction mechanism that activates a nonselective cationic cyclic ...
-
(PERGAMON-ELSEVIER SCIENCE, 2005-10-03)Three naturally occurring pyranosyl-like polyhalogenated metabolites 1-3 as well as their likely biogenetic precursor, the linear compound 4, have been isolated from the red alga Ptilonia magellanica. They are the first ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-06-01)Hereditary hemochromatosis (HH) is a condition in which intestinal iron absorption is greatly elevated. Present treatment is weekly phlebotomy, affecting quality of life and leading to recurrent infections. The iron ...
-
(ELSEVIER SCIENCE BV, 2005-01-31)We investigate the dynamic properties of a classical anisotropic Heisenberg chain interacting with an external magnetic field at different temperatures. Properties such as time-dependent energy autocorrelation and space-time ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-12)The concerted action of extracellular signals such as BMP, Wnt, FGF, RA and Notch activate a genetic program required to transform a naive ectodermal cell into a neural crest cell. In this review we will analyze the ...
-
(ELSEVIER SCIENCE BV, 2005-06-20)The thermal properties of poly(esters) containing Si and/or Ge in the main chain derived from the acid dichlorides bis(4-chloroformylphenyl)-dimethyl-silane, bis(4-chloroformyl-phenyl)-dimethyl-germane, bis(4-chlorofonny ...
-
(AMER CHEMICAL SOC, 2005-12-06)Surface-enhanced IR (SEIR) and Raman scattering (SERS) have been employed to study the adsorption of ester functionalized tert-butyl calix[4]arenes on Ag and Au nanostructured surfaces as well as their complexes with pyrene. ...
-
(ELSEVIER SCI LTD, 2005-05)We show how Chilean forest bird species richness, abundance and guild structure changes as a function of structural properties of forest stands. We surveyed bird assemblages in two old-growth (>200 years), two mid-successional ...
-
(ELSEVIER SCIENCE INC, 2005-02-01)We prove some results about nilpotent linear transformations. As an application we solve some cases of Albert's problem on the solvability of nilalgebras. More precisely, we prove the following results: commutative ...

Putative ClC-2 chloride channel mediates inward rectification in Drosophila retinal photoreceptors (SPRINGER, 2005-10)We report that Drosohhila retinal photoreceptors express inwardly rectifying chloride channels that seem to be orthologous to mammalian CIC-2 inward rectifier channels. We measured inwardly rectifying Cl- currents in ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-06-01)The interfacial properties ofpoly(maleic acid-alt-1-alkene) disodium salts at hydrocarbon/water interfaces are determined. In all the studied systems, the interfacial tension decreases markedly with the polyelectrolyte ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-11)Copper was removed from an acidic mine drainage (AMD) using a liquid emulsion membrane contactor. The acidic drainage was a harmful natural acidic solution generated by bioleaching and chemical leaching of copper and iron ...
-
(AMER SOC MICROBIOLOGY, 2005-10)We designed a multiplex PCR for the detection of all categories of diarrheagenic Escherichia coli. This method proved to be specific and rapid in detecting virulence genes from Shiga toxin-producing (stx(1), stx(2), and ...
-
(ELSEVIER, 2005-02-10)"Bailahuen" is the common name of a medicinal shrub native to Chile where this resinous herb is widely used for its liver stimulating properties. Although the official species is Haplopappus baylahuen Remy (Asteraceae), ...

(SOCIEDAD BIOLGIA CHILE, 2005)In this paper we develop a method to estimate lung Volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: ...
-
(ELSEVIER, 2005-02-11)Two hypotheses have attempted to explain the development of Mixed Paleofloras during the Cenozoic in South America. One of them postulates changes in the climatic tolerances of its component taxa and the other calls for ...
-
(ELSEVIER SCIENCE BV, 2005-03-14)Olfactory cilia contain cyclic nucleotide-gated and Ca2+-dependent Cl- conductances that underlie excitatory chemotransduction, and a Ca2+-dependent K+ (K-Ca) conductance, apparently involved in inhibitory transduction. ...
