(Blackwell Publishing Ltd, 2014)In some archaea, the phosphorylation of glucose and fructose 6-phosphate (fructose 6P) is carried out by enzymes that are specific for either substrate and that use ADP as phosphoryl donor. In the hyperthermophilic archaeon ...
-
(2011)An implementation of a novel strategy for cluster geometry optimization, using a stochastic method, is applied. This algorithm is based on the spirit of Big Bang theory. The strategy consists on a three-step procedure; a ...
-
(2012)The mammalian pulvinar complex is a collection of dorsal thalamic nuclei related to several visual and integrative processes. Previous studies have shown that the superficial layers of the superior colliculus project to ...
-
(Amer Physical Soc, 2016)The electronic structure of bilayer graphene under pressure develops very interesting features with an enhancement of the trigonal warping and a splitting of the parabolic touching bands at the K point of the reciprocal ...
-
(Universidad de Chile, 2008)Esta tesis está guiada principalmente en el trabajo de S.Tabachnikov [9]. En la tesis se estudia la dinámica del billar dual definido en el exterior' de una curva plana. suave a pedazos, cerrada simple. convexa. y que ...

(Springer, 2017)Bimetallic Au/Ag nanostructures have been included inside SiO2 by pyrolysis of the macromolecular complexes Chitosan center dot(MLn/M'Ln)(n)center dot SiO2 and PSP-4-PVP center dot(MLn/M'Ln)(n)center dot SiO2 with MLn = ...
-
(Sociedad Chilena de Quimica, 2013)Novel bimetallic Au/Ag superstructures have been prepared from solid-state pyrolysis of the macromolecular complexes Chitosan(MLn/M'Ln)n y PSP- 4-PVP×( MLn/M'Ln)n with MLn = AuCl3 and M'Ln = Ag(CF3SO3). The characterization ...

Binding of microtubule-associated protein 1B to LIS1 affects the interaction between dynein and LIS1 (PORTLAND PRESS LTD, 2005-07-15)For neuronal migration to occur, the cell must undergo morphological changes that require modifications of the cytoskeleton. Several different MAPs (microtubule-associated proteins) or actin-binding proteins are proposed ...
-
(SPRINGER, 2010-02-17)Natural products are recognized as an important source of new and better pharmaceuticals for the treatment of diseases such as tuberculosis. The azorellane and mulinane diterpenoids represent an interesting group of ...
-
(Universidad de Chile., 2021)El cobre (Cu) es uno de los principales micronutrientes para los organismos; sin embargo, su acumulación en altas concentraciones y su posterior traspaso a otros organismos a lo largo de la cadena trófica pueden causar ...
-
(1999)The aporphine alkaloids boldine and glaucine have been reported to show 'neuroleptic-like' actions in mice, suggesting that they may act as dopamine antagonists. We have found that in vitro boldine displaces specific ...
-
(Elsevier, 2020)An enriched fraction of an inhibitor of both the catalytic subunit of the cAMP-dependent protein kinase (PKA) from pig heart and a Trypanosoma equiperdum PKA catalytic subunit-like protein (TeqC-like) was obtained from the ...
-
(ROYAL SOCIETY, 2007-02-28)The perspective of 'biocomplexity' in the form of 'coupled natural and human systems' represents a resource for the future conservation of biodiversity hotspots in three direct ways: ( i) modelling the impact on biodiversity ...
-
(Universisdad de Chile, 1996)Los policlorobifenilos (PCBs) se encuentran entre los contaminantes clorados mas ampliamente distribuidos en la biosfera. Los PCBs son xenobioticos que han causado una gran preocupación debido a sus propiedades de persistencia ...
-
(Universidad de Chile, 2012)Organochlor¡nated pestic¡des such as Aldrin and Hexachlorobenzene, exhibit chemical characteristics that make them hazardous for people and environment. For this reason they were included in the so-called dirty dozen ...
-
(Universidad de Chile, 2010)Compuestos orgánicos tales como etoxilatos de nonilfenol y su producto de degradación nonilfenol, presentes en detergentes y en una gran variedad de insumos de uso masivo, son sustancias tóxicas, bioacumulables, ampliamente ...
-
(Kluwer Academic Publishers, 1997)The Chilean taxonomic community is reduced, with the largest fraction of taxonomists devoted to well known groups, such as vertebrates. Some invertebrates and plant taxa have no Chilean taxonomist working on them, all ...
-
(2013)In this work the available information from scientific and technical studies is compiled and analyzed, to determine the taxonomic composition and trophic structure of river communities belonging to five hydrological basins ...
