(Elsevier Ltd., 2011-10-06)Two fluorescence probes for the detection of cysteine (Cys), glutathione (GSH) and other biothiols, such as homocysteine (Hcy) and cysteinyl-glycine (Cys-Gly), were developed. These molecular probes are coumarin-based ...
-
(Springer, 2010-03-25)The continued advance of HIV-AIDS makes the development of relatively inexpensive, freely accessible, and mechanistically more diverse antiviral therapies an urgent need. Natural products are, directly or indirectly, ...
-
(Elsevier, 2012)We propose a model of competition of n species in a chemostat, with constant input of some species. We mainly emphasize the case that can lead to coexistence in the chemostat in a non-trivial way, i.e., where the n−1 ...
-
(Elsevier B.V., 2010-02-23)Nicotinic acetylcholine receptors influence striatal dopaminergic activity and its outcome on motor behavior. For these reasons, nicotinic receptors have been considered as therapeutically relevant targets for Parkinson's ...
-
(2012)A theoretical investigation of the adsorption of Mn single atoms and dimers on the (111) surface of Cu, Ag, and Au, within the framework of the density functional theory, is presented. First, the bulk and the clean ...
-
(Elsevier Science B.V., 1994-06-13)The representation of the electronic structure of intercalated 1T - TiS2 with lithium by a cluster approximation is giscussed. The electronic chemical potential, defined in the context of density functional theory, is ...
-
(John Wiley & Sons, 1994-10-14)The variation of the charge capacity of a double-layer 1T-TiS2 model system upon increasing intercalation with Lithium is examined at a molecular level. The charge capacity is modeled through the global hardness index of ...
-
(Sociedad Chilena de Química, 2003-09-22)We present a physically based treatment of the molecular rotational partition function for the case of the interaction of a macromolecular receptor with a small biologically active molecule. This leads to the proposal ...
-
(Elsevier B.V., 2012-01-16)The Raman and surface-enhanced Raman scattering (SERS) spectra of the C-terminal peptide of pigeon cytochrome C (PCC87-104), were recorded. This peptide is widely used to study the immune response in vivo. Hydrophobicity ...
-
(Elsevier, 2011)The reaction catalyzed by E. coli Pfk-2 presents a dual-cation requirement. In addition to that chelated by the nucleotide substrate, an activating cation is required to obtain full activity of the enzyme. Only Mn2+ and ...
-
(Springer, 2011)We studied lizard assemblages assessing abundance, richness, and nestedness in a fragmented landscape of central Chile including native temperate forest, forest fragments, and commercial pine plantations. Fragmentation and ...
-
(Blackwell, 2011)Aim The Chilean long-tailed snake (Philodryas chamissonis) has a wide distribution across different latitudes and ecosystems in Chile ranging from the south of the Atacama Desert (26 S) to the extremely humid Valdivian ...
-
(Springer, 2011)Twenty-first century climate model projections show an amplification of the annual cycle in tropical precipitation with increased strength in both wet and dry seasons, but uncertainty is large and few studies have examined ...
-
(SERVICIO NACIONAL GEOLOGIA MINERIA, 2011-01)Newly described outcrops, excavations and sediment cores from the region of Ultima Esperanza, Magallanes, contain tephra derived from the large late-glacial explosive RI eruption of the Reclus volcano in the Andean Austral ...
-
(PERGAMON-ELSEVIER, 2011)Many members of the benthic fauna of the Antarctic continental shelf share close phylogenetic relationships to the deep-sea fauna adjacent to Antarctica and in other ocean basins. It has been suggested that connections ...
-
(Elsevier, 2011-03-01)The along-fjord variability of nitrate and dissolved silicate was studied in a silled fjord, Seno Ballena, in the Strait of Magellan during flood and ebb tidal phases in December 2007. The spatial and temporal variability ...
-
(2011)In contrast to the UV-photoinduced ligand photoionization of the flavonoid complexes of FeIII, redox reactions initiated in ligand-to-metal charge-transfer excited states were observed on irradiation of the quercetin (1) ...
-
(Elsevier, 2011)Many organisms exhibit ontogenetic shifts in their diet and habitat use, which often exert a large influence on the structure and expected dynamics of food webs and ecological communities. Nevertheless, reliable methods ...
-
(SOC BIOLGIA CHILE, 2011)Digestive capabilities, such as the rates nutrient hydrolysis and absorption, may affect energy intake and ultimately feeding behavior. In birds, a high diversity in gut biochemical capabilities seems to support the existence ...
