(2012)Excitation properties of the isolated C 60 and (C 60) N model clusters (N = 2, 3, 4, 6 and 13) are studied using an a priori parameterized and self-consistent Hamiltonian, the Complete Neglect of Differential Overlap ...
-
(2012)A metastable carbon nanotube with single, double, and triple bonds has been predicted from abinitio simulation. It results from the relaxation of an ideal carbon nanotube with chirality (2,1), without any potential barrier ...
-
(2012)Cephalopods have two main defence strategies: the first consists on reducing the odds of being detected by a predator, while the second focuses on avoiding capture. The aim of this study was to understand the basic behavioural ...
-
(2012)Iron is an essential element for life on earth, participating in a plethora of cellular processes where one-electron transfer reactions are required. Its essentiality, coupled to its scarcity in aqueous oxidative environments, ...
-
(2012)Hallmarks of idiopathic and some forms of familial Parkinson's disease are mitochondrial dysfunction, iron accumulation and oxidative stress in dopaminergic neurons of the substantia nigra. There seems to be a causal link ...
-
(2012)The novel coumarin-based 'turn-on' fluorescent probe (E)-3-(2,5- dimethoxybenzylideneamino)-7-hydroxy-2H-chromen-2-one (MGM) was designed, synthesized, and characterized. This compound shows high selectivity for Cu +2, ...
-
(2012)The formation of the nervous systems requires processes that coordinate proliferation, differentiation and migration of neuronal cells, which extend axons, generate dendritic branching and establish synaptic connections ...
-
(2012)Flowering traits are becoming important breeding objectives in Eucalyptus cladocalyx. Previous studies have confirmed that the trees from Cowell, Australia, respond well for early flowering under the arid conditions in the ...
-
(2011)Boron is an essential trace element for plants and humans however it is still an open question what levels of boron are actually safe for humans. This study, conducted between 2006 and 2010, measured exposure levels of ...
-
(2012)Flexible and transparent polymer complexes prepared by blending chitosan (CS) with about 1 M of oligo-mercaptopropilsiloxane were functionalized by incorporating silver or gold nanoparticles in a concentration range of ...
-
(2012)In order to develop future therapeutic applications for cell penetrating peptides (CPPs), it is essential to characterize their internalization mechanisms, as they might affect the stability and the accessibility of the ...
-
(2012)One of the greatest challenges for conservation biology is providing solutions for endangered species in modern landscapes, usually with deficient biological information on how species respond to landscape disturbances. ...
-
(BioMed Central Ltd., 2012)© 2012 González-Wevar et al.; licensee BioMed Central Ltd. Background: Patagonia extends for more than 84,000 km of irregular coasts is an area especially apt to evaluate how historic and contemporary processes influence ...
-
(2012)Isolated closed basins provide a natural laboratory to study the differentiation among wild populations. Here we examined the phylogenetic relationships of the Southern Altiplano populations of Biomphalaria, a genus with ...
-
(2012)This article describes the basic prey requirements of Paraphysa sp., a small mygalomorph spider from the central Andes. Paraphysa sp. can be maintained in captivity using mealworms (Tenebrio molitor) as its primary food ...
-
(Wiley, 2012)Plant-animal interaction networks provide important information on community organization. One of the most critical assumptions of network analysis is that the observed interaction patterns constitute an adequate sample ...
-
(2012)We studied the renal morphology of 16 species of passerines to assess whether the composition of the diet of birds have been paralleled by differences in the characteristics of the kidneys. We determined the number and ...
-
(Elsevier, 2011)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 ...
