UN MODELO HIDRODINÁMICO-BAROTRÓPICO PARA LOS FIORDOS AUSTRALES DE CHILE ENTRE LOS 41° S Y LOS 46° S (Comité Oceanográfico Nacional, 2008-07)Modelling coastal-estuarine ecosystems, characteristic of the southern fjords of Chile, should be based on hydrodynamic models accounting for the water circulation and its forcing. In this work we describe a barotropic, ...

Cognitive impairment and Alzheimer's disease: Links with oxidative stress and cholesterol metabolism (BioMed Central, 2008)Oxidative stress has be en implicated in the progression of a number of neurodegenerative diseases, inc1uding Alzheimer's disease (AD), Parkinson's disease and amyotrophic lateral sclerosis. We carried out a~ in-depth ...
-
(Institute of Physics (IoP), 2008)In the present work, an assessment of the Physics research capacity in Chile is presented. For this, the period between 2000 and June 2005 has been studied. In this period almost 200 physicists have contributed to ...

(Sociedad de Neurología, Psiquiatría y Neurocirugía, 2010-03-03)El constante aumento en la expectativa de vida en la población mundial ha incrementado la preocupación hacia la búsqueda de la comprensión de la Enfermedad de Alzheimer (EA), así como de su diagnóstico temprano y tratamiento. ...
-
(IOS PRESS, 2009)Alzheimer’s disease (AD) is characterized by the accumulation of protein filaments, namely extracellular amyloid-β (Aβ) fibrils and intracellular neurofibrillary tangles, which are composed of aggregated hyperphosphorylated ...
-
(BLACKWELL, 2009)The idea that alterations in the brain immunomodulation are critical for Alzheimer’s disease (AD) pathogenesis provides the most integrative view on this cognitive disorder, considering that converging research lines ...
-
Mild cognitive impairment and Alzheimer patients display different levels of redox-active CSF iron (IOS PRESS, 2008)Oxidative stress constitutes a hallmark of Alzheimer’s disease (AD). Recent studies also point to redox active metals such as iron, copper and zinc in mediating oxidative stress in AD pathogenesis. However, the reactivity ...
-
(BENTHAM SCIENCE PUBL LTD, 2008-10)Hyperinsulinemia as well as type II diabetes mellitus are among the risk factors for Alzheimer´s disease (AD). However, the molecular and cellular basis that link insulin resistance disorders and diabetes with AD are far ...
-
(ROYAL SOC, 2007-11-01)In eusocial Hymenoptera, females are more tolerant towards nest-mate than towards non-nest-mate females. In solitary Hymenoptera, females are generally aggressive towards any conspecific female. Field observations of the ...
-
(AMER INST PHYSICS, 2008-01-17)The local softness of MgO, CaO, SrO, and BaO (100) surfaces has been studied using a model based on the local density of states. In all the species, the local softness chemical reactivity of oxygen atoms at the surface ...
-
(Bentham open, 2008-11-26)Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
-
(IOP PUBLISHING LTD, 2008-07-02)The classical action for a three-dimensional rotating particle with time-dependent angular velocity and that submitted to a general linear and quadratic time-dependent potential is explicitly calculated and, via path ...
-
(WILEY-V C H VERLAG GMBH, 2007-03)The definition of life has excited little interest among molecular biologists during the past half-century, and the enormous development in biology during that time has been largely based on an analytical approach in ...

Neuroinflammation: Implications for the pathogenesis and molecular diagnosis of Alzheimer's disease (ELSEVIER SCIENCE INC, 2007-05-31)During the past few years, an increasing set of evidence has supported the major role of deregulation of the interaction patterns between glial cells and neurons in the pathway toward neuronal degeneration. Neurons and ...

(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008-08-22)Phosphofructokinase-1 and -2 (Pfk-1 and Pfk-2, respectively) from Escherichia coli belong to different homologous superfamilies. However, in spite of the lack of a common ancestor, they share the ability to catalyze ...
-
(BIOMED CENTRAL LTD, 2007-10-03)Background: Interleukin-3 (IL-3) is an important glycoprotein involved in regulating biological responses such as cell proliferation, survival and differentiation. Its effects are mediated via interaction with cell surface ...
-
(ELSEVIER SCIENCE BV, 2003-11-24)The high-affinity copper transporter 1 (Ctr1) is a highly conserved transmembrane protein that mediates the internalization of copper ions from the extracellular medium. In this study, we have isolated the zebrafish ctr1 ...
-
(SPRINGER, 2007-03-01)Reversible glycosylated polypeptides (RGPs) are highly conserved plant-speciWc proteins, which can perform self-glycosylation. These proteins have been shown essential in plants yet its precise function remains unknown. ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2003-09-35)The genes that control development of embryonic melanocytes are poorly defined. Although transcription factor Ap-2a is expressed in neural crest (NC) cells, its role in development of embryonic melanocytes and other neural ...
