(John Wiley & Sons, Inc., 1996-03-22)The binding of apomorphines AM. to D1 and D2 dopamine receptors is analyzed through a formal quantum structure]activity relationship method. The calculations were carried out at the CNDOr2 level of the molecular orbital ...
-
(IANDS, 1994-07-25)In this article we propose a scientific approach to explain the fact that some near-death experiencers (NDErs) are able to recollect and verbalize real events occurring in the environment during the experience. Our model ...
-
(American Pharmaceutical Association, 1983-09-13)We have analyzed the dependence of the serotonin receptor binding affinity on the atomic net charges, superdelocalizabilities, mass, and moment of inertia in a group of indole derivatives. The approaches employed are a ...
-
(Springer, 2011)Studies in post-mortem tissues of patients with Parkinson’s disease (PD) and in mice treated with 6-hydroxydopamine have shown a decrease in the length of axon and dendrites of striatal neurons. However, the etiology of ...

(Sociedad Chilena de Neurología, Psiquiatría y Neurocirugía, 1987)In this work we flIIIllyze the problem fo human conciousness from a monist point of view, including the actual knowledge in neurobiology. Three questions are discussed: 1. Can we localize human conciousness in certain ...

A statistical thermodynamics interpretation of the solvations energy within the continuum approach (Sociedad Chilena de Química, 1989-03-14)En este trabajo, se presenta una discusión sobre la naturaleza fisica de la energia de solvatación basada en un modelo termodinámico estadistico. A partir de él se puede obtener una partición completa de la energia libre ...

(2011)The Notch signaling pathway plays an important role in development and physiology. In Drosophila, Notch is activated by its Delta or Serrate ligands, depending in part on the sugar modifi cations present in its extracellular ...
-
(Sociedad de Biología de Chile, 2011)Land use change is one of the main biodiversity threats. Due to this change, natural habitats such as the South American temperate rainforests have been rapidly degraded, fragmented, and lost. Consequently, the management and ...
-
(Sociedad de Neurología, Psiquiatría y Neurocirugía, 1994)Criminal behavior is analyzed using a multilevel interdisciplinary approach. Aggression is the basis of criminal behavior (CB). In .some situations, aggression leads to non adaptative relations with the environment. ...
-
(IANDS, 1993)This paper describes a possible near-death experience (NDE) among the Mapuche people of Chile. The individual reporting the experience was in a cataleptic-like state for two days, the experience itself occurring at ...
-
(Editorial Codelia, Publicaciones Científicas, 1984-11-24)On the basis of CNDO and INDO ca1culations, the trans and gauche isomers of the free radical n-perfluorobuthyl are established as the most probable structures in the conformational equilibrium. Spectral differences in ...

(Editorial Codelia, 1986)Self Consistent Reaction Field (SCRF) ealculations, including dielectric solvent effects, have been performed to analyze the relative stabilities of the different chernical species found in substitution reactions involving ...
-
(Springer, 2009-08-05)Iron is essential for crucial neuronal functions but is also highly toxic in excess. Neurons acquire iron through transferrin receptor-mediated endocytosis and via the divalent metal transporter 1 (DMT1). The N-terminus (1A, ...
-
(UNIV CHICAGO PRESS, 2009-10)This study tests the phylogenetic affinities of 11 South American species of Anemone s.l., including the closely related endemic segregate genera Barneoudia and Oreithales.We analyzed combined sequence data (chloroplast ...
-
(SPRINGER, 2009-08-23)Self-pollination mechanisms are often invoked to explain plant reproduction in environments devoid of pollinators. However, populations may evolve a diverse variety of strategies depending on the ecological context of ...
-
(AMER PHYSICAL SOCIETY, 2010-01-27)We perform density-functional-theory calculations of electronic core levels to obtain the tellurium x-ray photoelectron spectra in the amorphous solar-energy materials CdTeOx x=0.2, 1, 2, and 3 . We quantify the distribution ...
