Epidemiological and molecular analysis of Streptococcus pyogenes isolates causing invasive disease in Spain (1998-2009): comparison with non-invasive isolates
(Springer, 2011-10-01)
The incidence, clinical manifestations, and circulating clones involved in Streptococcus pyogenes invasive disease was analyzed in two regions of Spain between 1998 and 2009. The annual average incidence of invasive disease ...
Influence of the modification with MWCNT on the interlaminar fracture properties of long carbon fiber composites
(Elsevier, 2011-11-12)
This paper reports the processing of a carbon fiber reinforced epoxy composite with carbon nanotube integration and examines the potential improvement on the interlaminar toughness. Carbon nanotube enhanced composites were ...
Optimization of 100 µm alginate-poly-L-lysine-alginate capsules for intravitreous administration
(Elsevier, 2011-09-24)
The field of cell microencapsulation is advancing rapidly. Particle size plays a critical role in terms of biocompatibility and limits decisively its applicability. Producing reduced size microcapsules involves broadening ...
A clean up step of fat content previous to trace metal characterization in mussel tissues by inductively coupled plasma mass spectrometry
(Elsevier, 2011-05-24)
Inductively coupled plasma mass spectrometry analysis of trace and major elements of mussel tissues can be quickly and accurately analyzed after cleaning up the interfering fat content before the sample is digested in a ...
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 ...
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 ...
