Micro-Raman spectroscopic identification of natural mineral phases and their weathering products inside an abandoned zinc/lead mine
(Elsevier, 2011-01-23)
Mining activities provide a good source of minerals of different nature. On the one hand, the primary minerals for whose formation a geological time-scale is required. On the other hand, secondary minerals, formed from ...
Thermal Stability of Endohedral First-Row Transition-Metal TM@ZniSi Structures, i = 12, 16
(ACS, 2011-03-31)
The thermal stability of first-row transition-metal-doped TM@ZniSi nanoclusters, in which TM stands for the first-row transition metals from Sc to Zn and i = 12, 16, has been analyzed for the two lowest-lying spin states ...
Phylogenetic analysis of oligochaete Tubificinae (Annelida : Clitellata) based on mitochondrial sequence data
(CSIRO Publishing, 2011-11-18)
[ES]Se utilizaron secuencias parciales de los genes mitocondriales 16S rRNA y citocromo c oxidasa subunidad I (COI) (1) para resolver las relaciones internas de la subfamilia Tubificinae (Annelida: Clitellata) y (2) para ...
Separation and Purification of Hemicellulose by Ultrafiltration
(ACS, 2011-12-29)
[EN]During hydrolysis treatments, where the main objective is the solubilization of hemicelluloses, several undesirable reactions may occur. As a result, monomeric sugars and nonsaccharide compounds are obtained in the ...
HLA-DRB1*15:01 and multiple sclerosis: a female association?
(Sage, 2011-11-29)
Background: The association between multiple sclerosis (MS) and the HLA-DRB1*15: 01 haplotype has been proven to be strong, but its molecular basis remains unclear. Vitamin D receptor (VDR) gene variants and sex have been ...
Docosahexaenoic acid reduces cerebral damage and ameliorates long-term cognitive impairments caused by neonatal hypoxia-ischemia in rats
(Springer, 2011-10-29)
As the interest in the neuroprotective possibilities
of docosahexaenoic acid (DHA) for brain injury has grown in the recent years, we aimed to investigate the long-term effects of this fatty acid in an experimental model ...
Polymorphisms of the SLCO1B1 gene predict methotrexate-related toxicity in childhood acute lymphoblastic leukemia
(Wiley, 2011-10)
Background: Methotrexate (MTX) is an important component of the therapy for childhood acute lymphoblastic leukemia. Treatment with high-dose MTX often causes toxicity, recommending a dose reduction and/or cessation of ...
Influence of catchment processes on fluvial morphology and river habitats
(AIL, 2011)
Fluvial morphology is conditioned by three basic elements: flow regime, sediment yield and valley characteristics. These
elements are controlled by factors operating at different spatial and time scales, within and outside ...
Imaging the early stages of phospholipase C/sphingomyelinase activity on vesicles containing coexisting order-disorder and gel-fluid domains
(Elsevier, 2011-04)
[EN] The binding and early stages of activity of a phospholipase C/sphingomyelinase from Pseudomonas aeruginosa on giant unilamellar vesicles (GUV) have been monitored using fl uorescence confocal microscopy. Both the ...
Valores percibidos en el medio televisivo por adolescentes en contextos transculturales
(Grupo Comunicar, 2011-10-01)
[EN]This study was carried out on a sample group of 1,238 adolescents from eight different cultural contexts, and aimed to determine the values perceived by subjects in their favorite television characters. It also aimed ...
