Neutrophils of Centenarians Show Function Levels Similar to Those of Young Adults
(Wiley, 2008)
OBJECTIVES: To analyze several functions and antioxidant parameters of peripheral blood neutrophils from healthy centenarians (men and women) and compare them with those of healthy young (aged 25–35) and middle-aged (aged ...
Lexical tone and stress in Goizueta Basque
(Cambridge University Press, 2008)
Research in the past few decades has shown that Northern Bizkaian Basque possesses a pitch-accent system of the Tokyo Japanese type, with a contrast between lexically accented and unaccented words. There is, however, a ...
Restored quantum size effects of Pb overlayers at high coverages
(APS, 2007-04-10)
Abnormally large stability of Pb nanostructures grown on metallic or semiconductor substrates has been observed even for heights of about 30 monolayers. Using both density-functional theory calculations and analytical ...
Prevalence and risk factors of behavioural changes associated with age-related cognitive impairment in geriatric dogs
(Wiley, on behalf of the British Small Animal Veterinary Association, 2009)
Objectives: The aim of this study was to describe the prevalence and severity of behavioural changes associated with age and their relationship to risk factors such as sex, reproductive status, bodyweight and age.
Methods: ...
The conserved helix C region in the superfamily of interferon-gamma /interleukin-10-related cytokines corresponds to a high-affinity binding site for the HSP70 chaperone DnaK.
(Elsevier, 2002-07-12)
HSP70 chaperones mediate protein folding by ATP-dependent interaction with short linear peptide segments that are exposed on unfolded proteins. The mode of action of the Escherichia coli homolog DnaK is representative of ...
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 ...
