(SPRINGER, 2005-10-03)Mutations in the HFE gene result in hereditary hemochromatosis, a disorder of iron metabolism characterized by increased intestinal iron absorption. Based on the observation that ectopic expression of HFE strongly inhibits ...
-
(ELSEVIER SCI LTD., 2006-03-29)We report here the protective effect against piscirickettsiosis elicited in fish by a mixture of recombinant proteins. A comparative genomics strategy was used on a genomic library of Piscirickettsia salmonis in order to ...
-
(BLACKWELL PUBLISHING, 2009-01-09)The brain uses massive amounts of oxygen, generating large quantities of reactive oxygen species (ROS). Because of its lipid composition, rich in unsaturated fatty acids, the brain is especially vulnerable to ROS. ...
-
(SOCIEDAD BIOLGIA CHILE, 2005-05-05)Interactions of micronutrients can affect absorption and bioavailability of other nutrients by a number of mechanisms. In aqueous solutions, and at higher uptake levels, competition between elements with similar chemical ...
-
(AMER CHEMICAL SOC,, 2006-04-20)Phosphofructokinase-2 (Pfk-2) from Escherichia coli belongs to the ribokinase family of sugar kinases. One of the signatures observed in amino acid sequences from the ribokinase familiy members is the NXXE motif, which ...
-
(Elsevier B.V., 2006-10-21)The tumor necrosis factor alpha (TNFα) plays a dual role in producing either neurodegeneration or neuroprotection in the central nervous system. Despite that TNFα was initially described as a cell death inductor, ...
-
(ELSEVIER SCIENCE BV, 2006-01-19)In response to hypoxia, chemoreceptor cells of the carotid body (CB) release transmitters, which acting on the petrosal ganglion (PG) neuron terminals, increase the chemoafferent discharge. Additionally, vasoactive ...
-
(ELSEVIER SCIENCE BV, 2007-02)Chemoreceptor (glomus) cells of the carotid body are synaptically connected to the sensory nerve endings of petrosal ganglion (PG) neurons. In response to natural stimuli, the glomus cells release transmitters,which ...
-
(Facultad de Agronomía e Ingeniería Forestal, Pontificia Universidad Católica de Chile ., 2006-09)The cell wall plays a major role in determining the expansion, growth and shape of plant cells, and thus of the plant itself. Additionally, cell wall breakdown products are used as developmental signals. Moreover, the ...
-
(Elsevier Ltd., 2005-08-24)This article analyses the work of Robert Rosen on an interpretation of metabolic networks that he called ðM;RÞ systems. His main contribution was an attempt to prove that metabolic closure (or metabolic circularity) could ...
-
(SOCIEDAD BIOLGIA CHILE, 2005-05-24)Hepcidin (Hepc) is a 25 amino acid cationic peptide with broad antibacterial and antifungal actions. A likely role for Hepc in iron metabolism was suggested by the observation that mice having disruption of the gene encoding ...
-
(COMPANY OF BIOLOGISTS LTD, 2006-10-30)A number of psychiatric and neurodegenerative disorders, such as Alzheimer’s disease, are characterized by abnormalities in the neuronal cytoskeleton. Here, we find that the enhancement in actin polymerization induced ...
-
(SPRINGER, 2010-10)Despite the increasing claims that structural complexity in agroforestry plantations is a key variable for enhancing bird biodiversity, few studies have experimentally manipulated the understory component of structural ...
-
(OPTICAL SOC AMER, 2010-09-01)We analyze localization of light in honeycomb photonic lattices restricted in one dimension, which can be regarded as an optical analog of graphene nanoribbons. We discuss the effect of lattice topology on the properties ...
-
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2010-11-01)The tectofugal pathway (retina – optic tectum – nucleus rotundus – entopallium) is a prominent route mediating visual discrimination in diurnal birds. Several lines of evidence have shown that at the tecto-rotundal ...
-
(UNIV SZEGED, BOLYAI INSTITUTE, 2010)In this paper we investigate the existence of the periodic solutions of a quasilinear differential equation with piecewise constant argument of generalized type. By using some fixed point theorems and some new analysis ...
-
(AMER INST PHYSICS, CIRCULATION & FULFILLMENT DIV, 2010-08)For families of magnetic pseudodifferential operators defined by symbols and magnetic fields depending continuously on a real parameter epsilon, we show that the corresponding family of spectra also varies continuously ...
-
(2010)1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, ...
-
(2010)Signal transduction depends critically on the spatial localization of protein constituents. A key question in odor transduction is whether chemotransduction proteins organize into discrete molecular complexes throughout ...
-
(Elsevier, 2010)We herein report on the group electrophilicity of molecular fragments present in the title compounds to describe leaving group abilities in reactions of aryl benzoates toward CN . It is found that the presence ...
