(Springer, 2013)The invasion or expansion of non-native species into new geographic areas can pose a major threat to the conservation of biodiversity. These threats are augmented when the newly-arrived species interacts with native ...
-
(Springer, 2013)This study investigates the variations in the chemical profile, free radical scavenging, antioxidant and gastroprotective activities of licorice extracts (LE) from plants harvested during the months of February to November. ...
-
(Springer, 2013)The stronger antioxidant capacity of the flavonoid quercetin (Q) compared with taxifolin (dihydroquercetin, T) has been the subject of previous experimental and theoretical studies. Theoretical work has focused on the ...
-
(Springer, 2013)Rationale Neuronal nicotinic acetylcholine receptors (nAChRs) are pharmacological targets that have recently been implicated in the reinforcing effects ofmany drugs of abuse, including ethanol. Varenicline and cytisine ...
-
(The American Society of Tropical Medicine and Hygiene, 2013)We evaluated Trypanosoma cruzi infection in 397 wild Mepraia gajardoi specimens from five coastal localities in northern Chile by detection of minicircle DNA by polymerase chain reaction. The wild capture sites were ...
-
(Elsevier GmbH., 2013)The nurse-protégé hypothesis states that adult plants of one species provide micro-environmental conditions that favor the establishment of seedlings of a second species with no effect for the first species. Several studies ...
-
(Springer-Verlag Berlin Heidelberg, 2013)Key message The study determined the tolerance of Aloe vera to high temperature, focusing on the expression of hsp70, hsp100 and ubiquitin genes. These were highly expressed in plants acclimated at 35 C prior to a ...
-
(IOP Publishing Ltd and Deutsche Physikalische Gesellschaft, 2013)We experimentally observe anomalous wavepacket evolution in a realization of a one-dimensional finite binary Anderson model in the presence of short-range correlations. To this end, we employ weakly-coupled optical waveguides ...
-
(Elsevier Ltd., 2013)A series of eight complexes with general structure [ARe(CO)3D]+, (A = NO2phen, NO2dppz; D = TBP, MOP, DMAP, PEPN) were synthesized and characterized by IR, NMR, UV–Vis spectroscopy and cyclic voltammetry. The donor and ...
-
(Hindawi, 2013)Regulatory T cells are a specific subset of lymphocytes that suppress immune responses and play a crucial role in the maintenance of self-tolerance. They can be generated in the thymus as well as in the periphery through ...
-
(Hindawi, 2013)One of the greatest advances in medicine during the past century is the introduction of organ transplantation. This therapeutic strategy designed to treat organ failure and organ dysfunction allows to prolong the survival ...
-
(PNAS, 2013-07)The assembly of regional biotas and organismal responses to anthropogenic climate change both depend on the capacity of organisms to adapt to novel ecological conditions. Here we demonstrate the concept of evolutionary ...
-
(Andean Geology, 2013-01)The age of the Navidad Formation in central Chile has always been controversial, mainly due to the conflicting age ranges indicated by its macro- and microfossils. Macrofossils are generally interpreted as having ...
-
(Elsevier, 2013)The ligands of type pyrazino[2,3-f][1,10]phenanthroline, R2ppl, with R = CN, COOH, COOEt or OH, were synthesized and used as precursors for obtaining the corresponding series of complexes of type [Ru(dmbpy)2R2ppl](PF6)2, ...
-
(2013)The strength of key interfacial contacts that stabilize protein–protein interactions have been studied by computer simulation. Experimentally, changes in the interface are evaluated by generating specific mutations ...
-
(Springer, 2013-06-18)The arrival of exotic pollinators to new habitats may introduce new patterns of floral preference and foraging behavior that modify the structure of the resident plant-pollinator community. The aim of this paper is to ...
-
(2013)Despite of being structurally simpler and species-impoverished than natural forests, agroforestry plantations can act as a secondary habitat for native species and sustain some biodiversity. In particular, insectivores ...
-
Effect of Unsaturation on the Absorption of Ethane and Ethylene in Imidazolium-Based Ionic Liquids (2013)The influence of the presence of imidazolium side chain unsaturation on the solubility of ethane and ethylene was studied in three ionic liquids: 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide-saturated ...
-
(2013)Darwin’s frogs (Rhinoderma darwinii and R. rufum) are two species of mouth-brooding frogs from Chile and Argentina. Here, we present evidence on the extent of declines, current distribution and conservation status of ...
-
(Springer, 2013)The electronic structure and spectroscopic properties of [Au3(μ-C(OEt) 0 NC6H4CH3)3]n-(C6F6)m and [Au3(μ-C2,N3-bzim)3]n-(Ag+)m were studied at the B3LYP, PBE and TPSS levels. The interaction between the [Au3] cluster ...
