In vitro activities of retapamulin and 16 other antimicrobial agents against recently obtained Streptococcus pyogenes isolates
(ASM, 2011-04-28)
Retapamulin in vitro activity against 400 Streptococcus pyogenes clinical isolates obtained from skin, pharynx, ear fluid, and blood samples recovered from 2007 to 2009 was studied. The isolates belonged to 26 different ...
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 ...
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 ...
