(WILEY-LISS, 2006-10)Reactive astrocytes surround amyloid depositions and degenerating neurons in Alzheimer's disease (AD). It has been previously shown that P-amyloid peptide induces inflammatory-like responses in astrocytes, leading to ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2006-03)In a screening of Basidiomycete cultures isolated from marine invertebrates collected along the Chilean coastline for the production of antibiotics we identified a Penicillium brevicompactum strain as a producer of metabolites ...
-
(AMERICAN PHYSICAL SOC, 2006-08-25)We report on the observation of surface gap solitons found to exist at the interface between uniform and periodic dielectric media with defocusing nonlinearity. We demonstrate strong self-trapping at the edge of a LiNbO3 ...
-
(AMER INST PHYSICS, 2006-12-07)An alternative strategy to find the minimal energy structure of nanoclusters is presented and implemented. We use it to determine the structure of metallic clusters. It consists in an unbiased search, with a global minimum ...
-
(ELSEVIER, 2006-04-15)Opuntia scrublands are important ecological-economic systems in the Andean area. They perform a major role protecting slopes against erosion, improving the soil properties and providing a variety of products employed in ...
-
(ALPHAMED PRESS, 2006-10)Adult stem cells reside in different tissues and organs of the adult organism. Among these cells are MSCs that are located in the adult bone marrow and NSCs that exist in the adult central nervous system (CNS). In ...
-
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2006-04-07)The folding of glycoproteins in the endoplasmic reticulum (ER) depends on a quality control mechanism mediated by the calnexin/calreticulin cycle. During this process, continuous glucose trimming and UDP-glucose-dependent ...
-
(ELSEVIER, 2006-08-30)We investigate possible interactions between acetylcholine (ACh)- and adenosine 5'-triphosphate (ATP)-induced responses of petrosal ganglion, where the perikarya of most sensory neurons of the glossopharyngeal nerve are ...
-
(SOC GENERAL MICROBIOLOGY, 2006-01)It has been postulated that inorganic polyphosphate (polyp) and transport of metal-phosphate complexes could participate in heavy metal tolerance in some bacteria. To study if such a system exists in archaea, the presence ...

Nonadditive effects of flower damage and hummingbird pollination on the fecundity of Mimulus luteus (SPRINGER, 2006-10)Flower herbivory and pollination have been described as interactive processes that influence each other in their effects on plant reproductive success. Few studies, however, have so far examined their joint effects in ...
-
(AMER ACAD PEDIATRICS, 2006-05)OBJECTIVE. Cellular immunity has classically been described as the defense mechanism for viral infections. The development of cellular or humoral immune responses will depend on a repertoire of cytokines produced by numerous ...
-
(SPRINGER, 2006-01)As a consequence of the increasing importance of hydrogen peroxide in plant metabolism, more efficient methods are required for accurate determinations of its concentration in plant tissue and organs. Here we present a ...
-
(BOTANICAL SOC AMER INC, 2006-07)Concerted changes in flower morphology and pollinators provide strong evidence on adaptive evolution. Schizanthus (Solanaccae) has zygomorphic flowers and consists of 12 species of annual or biennial herbs that are distributed ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-11)A new method for the determination of Fe-Total and Cu is proposed. The method is based on the formation of the iron and copper complexes with 5-sulfosalicylic acid (SSA), the optimal conditions were found, using SSA 5.1 g ...
-
(SPRINGER, 2006-10)We present evidence of differential maternal allocation to eggs in response to manipulated male attractiveness in the migratory pied flycatcher (Ficedula hypoleuca). We manipulated the size of a male secondary sexual trait, ...
-
(2006-08-07)The stability, electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bilines nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations. Our results show that Fe ...

(AMER INST PHYSICS, 2006-08-28)The stability and electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bi-line nanostructure on the H/Si(001) surface are addressed by spin-density functional calculations. Our results show that ...
-
(ELSEVIER, 2006-09-15)The monovacancy and the divacancy in single-walled carbon nanotubes (CNTs) are addressed by spin-density functional calculations. We study these defects in four nanotubes, the armchair (6,6) and (8,8) and the zigzag (10, ...
-
(AMER CHEMICAL SOC, 2006-06-27)We report the observation of urchin-like nanostructures consisting of high-density spherical nanotube radial arrays of vanadium oxide nanocomposite, successfully synthesized by a simple chemical route using an ethanolic ...
