Phenotypic and genotypic characterization of Streptococcus pyogenes isolates displaying the MLSB phenotype of macrolide resistance in Spain, 1999 to 2005
(2007-01-22)
The aim of this study was to describe the genetic characteristics of Streptococcus pyogenes showing the MLSB phenotype of macrolide resistance from 1999 to 2005 in Spain and to highlight the substantial increase in these ...
Positron lifetime calculation of the elements of the periodic table
(IOP, 2007-04-10)
Theoretical positron lifetime values have been calculated systematically for most of the elements of the periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the electronic ...
Ceramide-enriched membrane domains in red blood cells and the mechanism of sphingomyelinase-induced hot-cold haemolysis
(American Chemical Society, 2008-10-28)
Hot-cold hemolysis is the phenomenon whereby red blood cells, preincubated at 37 °C in
the presence of certain agents, undergo rapid hemolysis when transferred to 4 °C. The mechanism of this
phenomenon is not understood. ...
Relationship between vegetation diversity and soil functional diversity in native mixed-oak forests
(Elsevier, 2007-05-22)
Most studies on the interactions between aboveground vegetation and belowground soil diversity have been carried out in microcosms or manipulated field plots. In the current study, we investigated the relationship between ...
High Mitochondrial DNA Stability in B-Cell Chronic Lymphocytic Leukemia
(Public Library Science, 2009-11-18)
Background: Chronic Lymphocytic Leukemia (CLL) leads to progressive accumulation of lymphocytes in the blood, bone marrow, and lymphatic tissues. Previous findings have suggested that the mtDNA could play an important role ...
Synthesis and characterization of epoxy polymers containing azobenzene groups that exhibit optical birefringence
(2007-12-03)
A push–pull azo dye (DO3) was used as photosensitive substance to satisfactorily synthesize new epoxy polymers containing azo groups covalently linked. Three different amines BA, TA and MXDA were used as hardeners. Materials ...
