(Springer, 2014)Coalescing macroalgae may fusewith conspecifics, forming genetically heterogeneous entities known as chimera. This process has been shown in taxa from roughly half the red algal orders and in the Codium species, a green ...
-
(American Chemical Society, 2014)Acidithiobacillus ferrooxidans is an extremophilic bacterium used in biomining processes to recover metals. The presence in A. ferrooxidans ATCC 23270 of canonical copper resistance determinants does not entirely explain ...
-
(FEBS, 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 ...
-
(Elsevier, 2014)Glucocorticoids are essential for life and their secretion is regulated by the hypothalamic–pituitary–adrenal axis (HPA). The HPA axis is often divided into two components: baseline glucocorticoids levels and stress ...
-
Neogenin1 is a Sonic Hedgehog target in medulloblastoma and is necessary for cell cycle progression (UICC, 2014)The canonical Sonic Hedgehog (Shh)/Gli pathway plays multiples roles during central nervous system (CNS) development. To elucidate the molecular repertoire of Shh mediators, we have recently described novel transcriptional ...
-
(Elsevier, 2014)Proteins involved in bacterial cell division often do not have a counterpart in eukaryotic cells and they are essential for the survival of the bacteria. The genetic accessibility of many bacterial species in combination with ...
-
(Wiley, 2014)The nucleus geniculatus lateralis pars ventralis (GLv) is a prominent retinal target in all amniotes. In birds, it is in receipt of a dense and topographically organized retinal projection. The GLv is also the target ...
-
(Springer, 2014)Copper plays a key role in aerobic cell physiology mainly related to mitochondrial metabolism. This element is also present at higher than basal levels in some central nuclei and indeed, current evidence support copper’s ...
-
(Elsevier, 2014)We describe a new specimen of an elasmosaurid plesiosaur from the upper Maastrichtian of central Chile. The specimen includes a relatively complete dorso-caudal series, a few cervical vertebrae, and a fragmentary pelvic ...

(The Company of Biologists Ltd, 2014)Insulin signaling includes generation of low levels of H2O2; however, its origin and contribution to insulin-stimulated glucose transport are unknown. We tested the impact of H2O2 on insulin-dependent glucose transport ...
-
(ACS, 2014)The origin of catalysis and selectivity induced by room temperature ionic liquids in several organic reactions has putatively been associated with the concept of cation ef fect (hydrogen bond donor ability of the ionic ...
-
(PLOS Neglected Tropical Diseases, 2014-02)Trypanosoma cruzi calreticulin (TcCRT) is a virulence factor that binds complement C1, thus inhibiting the activation of the classical complement pathway and generating pro-phagocytic signals that increase parasite ...
-
(Elsevier, 2014)Three coumarin-derived fluorescent probes, 3-acetyl-7-[(6-bromohexyl)oxy]-2H-chromen-2-one (FM1), 7-[(6-bromohexyl)oxy]-4-methyl-2H-chromen-2-one (FM2) and ethyl 2-{7-[(6-bromohexyl)oxy]-2-oxo- 2H-chromen-4-yl}acetate ...
-
(Elsevier, 2014)Starting with a boundary triangulation an algorithm automatically generates graded densities of triangular elements inside arbitrary polygonal domains. Interior nodes generated inside acute triangles receive spacing ...
-
(Elsevier, 2014)Consumption of psychoactive substances has been important in the lives of indigenous American people for several millennia. While numerous studies have reported the occurrence of smoking pipes at archaeological sites, ...
-
(ACS, 2013)A system in a spatially (quasi-)degenerate ground state responds in a qualitatively different way to a change in the external potential. Consequently, the usual method for computing the Fukui function, namely, taking ...
-
(Elsevier, 2014)In this Letter we present a new probe, (E)-7-(diethylamino)-2-oxo-2H-chromene-3-carbaldehyde oxime (JB), which can detect Cu2+ ions in HEPES buffer under physiological conditions. Benesi–Hildebrand and Job plots demonstrate ...
-
(Elsevier, 2014-06)Most of the current metric indexes focus on indexing the collection of reference. In this work we study the problem of indexing the query set by exploiting some property that query objects may have. Thereafter, we present ...
-
(Springer-Verlag, 2014)We study how the opinions of a group of individuals determine their spatial distribution and connectivity, through an agent-based model. The interaction between agents is described by a Hamiltonian in which agents are ...
