Excellent results were obtained when the blood-scaled PBIF was prospectively applied to the subjects in Group 2 (V-T ratio 1.02 +/- 0.05; mean +/- SD) and Group 3 (V-T ratio 1.03 +/- 0.04). Equally accurate results were obtained for two subpopulations of subjects drawn from Groups 2 and 3 who had very differently shaped (i.e. “flatter” or “steeper”) input functions compared to PBIF (V-T ratio 1.07 +/- 0.04 and 0.99 +/- 0.04, respectively).\n\nResults obtained via PBIF were equivalent to those obtained via IDIF (V-T ratio 0.99 +/- 0.05 and 1.00 +/- 0.04 for

healthy subjects and MDD patients, respectively). Retest variability of PBIF was equivalent to that obtained with full input function and IDIF (14.5%, 15.2%, and 14.1%, respectively). Protein Tyrosine Kinase inhibitor Due to [C-11](R)-rolipram arteriovenous differences, venous samples could not be substituted for arterial A-1210477 samples. With both IDIF and PBIF, depressed patients had a 20% reduction in [C-11](R)-rolipram binding as compared to control (two-way ANOVA: p = 0.008 and 0.005, respectively). These results were almost equivalent to those obtained using 23 arterial samples.\n\nConclusion: Although some arterial samples are still necessary,

both PBIF and IDIF are accurate and precise alternatives to full arterial input function for [C-11](R)-rolipram PET studies. Both techniques give accurate results with low variability, even for clinically different groups of subjects and those with very differently shaped input functions.

“A high thermal conductivity novolac/nickel/graphite nanosheet (novolac/Ni/NanoG) composite was synthesized through in situ polymerization. Graphite nanosheet (NanoG) was prepared by sonicating expanded graphite (EG) in an aqueous alcohol solution

and was plated with nickel through an electrodeposition method. The X-ray diffraction spectrum shows that nickel was successfully plated onto the graphite surface and the nickel thickness is about 27.89 nm. The microstructures of the Ni/NanoG were characterized by scanning electron microscopy and transmission electron microscopy. The results reveal that nickel particles with the average diameter of 25 nm are coated on NanoG surface homogeneously and densely. Energy dispersive spectrometry spectrum confirms that the Ni content coated on NanoG surface, whose atomic percentage is 61%, is much higher than that of C element. The values predicted by theoretical model were underestimated the thermal conductivity of novolac/Ni/NanoG composites. Among NG, EG, NanoG, and Ni/NanoG four kinds of particles, the Ni/NanoG improved the thermal conductivity of novolac resin significantly. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
