We discuss various extensions to the technique, including the possibility of recovering the cooling function from large-signal measurements of the resonance curve. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3517152]“
“This study investigated the optimal schedule for home blood pressure (HBP) monitoring that has the greatest prognostic ability and provides the most reliable assessment of HBP. The Didima

study assessed the value of HBP (duplicate morning and evening measurements, 3 days) in predicting cardiovascular events in the general population (662 adults, 8.2 +/- 0.2 years follow-up). Criteria for the optimal monitoring schedule were stabilization of mean HBP, its variability (standard deviation (s.d.)) and hazard ratios (HRs) of cardiovascular events per 1 mm Hg HBP increase. By averaging more Compound C chemical structure readings (1-12), there was a progressive decline in average HBP and its s.d. and increase in HR, with most of these benefits achieved on the second day (8 readings) and little additional benefit obtained on the third day

(12 readings). The first day gave higher and more unstable HBP values (higher s.d.) with less prognostic ability (lower HR). The first HBP readings per occasion gave higher values but with similar prognostic ability as the second readings taken 1 min later. There was little difference in average HBP between morning find more and evening readings with no Apoptosis Compound Library manufacturer prognostic superiority of morning readings. In conclusion, by averaging more readings the average HBP and its variability are reduced and the prognostic ability improved. Any aspect of HBP monitoring (first or second readings, morning or evening) has similar prognostic ability. The first day gives higher and unstable values with lower prognostic ability and should be better discarded. These data validate the HBP monitoring schedule proposed by the European Society of Hypertension.

“Elastomeric compounds from hydrogenated acrylonitrile butadiene rubber, organomodified clay,

and perfluoropolyether (PFPE) additives were prepared. Characterization of the materials included X-ray diffraction, dynamic mechanical analysis (DMA), tensile mechanical properties testing, environmental scanning electron microscopy, and solvent permeability measurements, from which the solubility coefficient (S) and diffusion coefficient (D) values were determined. A synergistic effect of the two additives was observed because the presence of clay reduced D, whereas PFPE mainly decreased S. Increasing the mixing time facilitated the dispersion of the clay layers. DMA and the diffusivity data were used to estimate the aspect ratios of the solid inclusions in the rubber.
