A model is presented which quantifies the relationship between the specific contact BEZ235 resistance and the true contact area (which is a function of the surface roughness and applied load). Through the true contact area, the integrity of a bonded interface may be predicted from the electrical measurement of the contact resistance.”
“Background-Transforming growth factor (TGF)-beta is a multifunctional peptide that is important in T-cell activation and cardiovascular remodeling, both of which are
important features of Kawasaki disease (KD). We postulated that variation in TGF-beta signaling might be important in KD susceptibility and disease outcome.
Methods and Results-We investigated genetic variation in 15 genes belonging to the TGF-beta pathway in a total of 771 KD subjects of mainly European descent
from the United States, the United Kingdom, Australia, and the Netherlands. We analyzed transcript abundance patterns using microarray and reverse transcriptase-polymerase chain reaction for these same genes, and measured TGF-beta 2 protein levels in plasma. Genetic variants in TGFB2, TGFBR2, and SMAD3 and their haplotypes were consistently and reproducibly associated with KD susceptibility, coronary artery aneurysm formation, aortic root dilatation, and intravenous immunoglobulin treatment ALK inhibitor response in different cohorts. A SMAD3 haplotype associated with KD susceptibility replicated in 2 independent cohorts and an intronic single nucleotide polymorphism in a separate
haplotype block was also strongly associated (A/G, rs4776338) MEK inhibitor (P=0.000022; odds ratio, 1.50; 95% confidence interval, 1.25 to 1.81). Pathway analysis using all 15 genes further confirmed the importance of the TGF-beta pathway in KD pathogenesis. Whole-blood transcript abundance for these genes and TGF-beta 2 plasma protein levels changed dynamically over the course of the illness.
Conclusions-These studies suggest that genetic variation in the TGF-beta pathway influences KD susceptibility, disease outcome, and response to therapy, and that aortic root and coronary artery Z scores can be used for phenotype/genotype analyses. Analysis of transcript abundance and protein levels further support the importance of this pathway in KD pathogenesis. (Circ Cardiovasc Genet. 2011; 4: 16-25.)”
“Deguelia duckeana is popularly known as timbo and used by indigenous people as ictiotoxic. On account of there being no literature pertaining to the chemical profile or biological activity of this plant, the hexane, methanol and aqueous crude extracts from leaves, stems and roots were assayed that presented very high cytotoxic potential against Artemia salina, achieving 100% mortality in up to 5.0 mu gmL(1) concentration, but lower antioxidant potential on 2,2-diphenyl-1-picryl-hydrazyl and Fe3+/Phenanthroline assays.
