Eligible patients received Tacrolimus QD or Tacrolimus BID. PK profiles were obtained following the first tacrolimus dose (day 1), and twice under steady-state conditions. As secondary objectives, efficacy and safety parameters were also evaluated. Sixty-six patients completed

all PK profiles (34 Tacrolimus QD, 32 Tacrolimus BID). Mean AUC(0-24) of tacrolimus on day 1 was approximately 30% lower for Tacrolimus QD than Tacrolimus BID (232 and 361 ng.h/mL, respectively), but was comparable by day 4. There was a good correlation and a similar relationship VX-680 mouse between AUC(0-24) and C(min) for both formulations. Efficacy and safety data were also comparable over the 6-week period. Tacrolimus QD can be administered once daily in the morning on the basis of the same systemic exposure and therapeutic drug monitoring concept as Tacrolimus BID.”
“We report morphology and mechanical properties

of natural nanoclay incorporated spunbond polypropylene composite webs. Nanocomposite spunbond webs were produced with up to 5 wt % natural nanoclay additives on Reicofil (R)-2 spunbond line. Influence this website of nanoclay on the resin rheological properties, processibility, and mechanical properties of webs were studied. Wide angle X-ray diffraction and transmission electron microscopy analysis were used to investigate the nanocomposite morphology. Intercalated and flocculated morphology was observed for all the concentrates and for all the spunbond fiber webs. The microstructure and polymer morphology in the presence of additives was characterized using a polarized optical microscope. At higher percentage, excess clay platelets were excluded out of the spherulite boundaries. About 20-30% increase in tear strength was observed for webs with up to 2 wt % nanoclay additives. Compared with the control polypropylene spunbond web, nanoclay reinforced samples showed better dimensional stability.

Different HIF pathway failure mode was observed for spunbond webs with additives. Spunbond webs with even as low as 1 wt % clay retain their morphology and integrity in bond point after thermal bonding. Nanoclay incorporated spunbond webs showed significant improvements in the stiffness. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 3141-3155, 2010″
“The strain mediated microwave magnetoelectric coupling is studied in bilayers of ferrites with cubic anisotropy and piezoelectrics. The strength of magnetoelectric coupling is determined from data on ferromagnetic resonance frequency shift Delta f versus applied electric field E. Studies at 6-10 GHz on samples of nickel zinc ferrite and polycrystalline lead zirconium titanate, lead magnesium niobate-lead titanate or lead zinc niobate-lead titanate (PZN-PT) show shifts Delta f on the order of 30-150 MHz for E= 10 kV/cm. Bilayers of nickel zinc ferrite and PZN-PT demonstrated the highest magnetoelectric coefficient of 5.3 Oe cm/kV.
