OD was searched in 1906 patients treated and untreated in essential hypertensives with normal echocardiographic LVMI as defined by two sets of gender-specific criteria based on LV mass (LVM) indexed to body surface area (125 gm(-2) in men and 110 gm(-2) in women) and height(2.7) (49 gm(-2.7) Luminespib supplier in men and 45 gm(-2.7) in women). Overall, 568 patients (29.8%), fulfilled the criteria for LVCR. Prevalence rates of carotid plaque, carotid intima-media (IM) thickening, grade II retinopathy and microalbuminuria (MA) were significantly higher in patients with LVCR compared with those with normal geometry (53, 24, 22, 10% versus 38, 15, 15, 7%, respectively, P<0.01, at least). Furthermore, an independent association between LVCR and continuous variables of OD such as carotid IM thickness (P<0.0001) Selleckchem BAY 63-2521 and MA (P=0.004) was confirmed by a multivariate analysis. Our results indicate that LVCR identified by updated, less conservative, diagnostic criteria, is strongly associated with subclinical vascular and renal alterations of adverse prognostic significance. These findings support the view that LVCR should
be searched for and regarded as a marker of target OD with an additional value for cardiovascular risk stratification in patients with normal LVM. Journal of Human Hypertension (2010) 24, 380-386; doi:10.1038/jhh.2009.87; published online 19 November 2009″
“In this article, we report a novel method to synthesize polyaniline (PANI) nanocomposite. Chitin and PANI are dissolved in a common solvent, N,N-dimethyl acetamide, with 5% LiCl, and the solution is irradiated with 8 MeV electron beam for different doses, nano-particles of PANI in chitin is obtained. The characterization of the composite was done by UV-vis absorption SYN-117 inhibitor spectrum, FTIR, thermogravimetric analysis (TGA), X-ray diffraction,
scanning electron microscopic (SEM), and DC conductivity studies. UV-vis studies show conversion of emeraldine base form to leucoemaraldine base. FTIR studies show interaction between chitin and PANI. SEM analysis of irradiated composite shows formation of PANI particulates. Average particle size varies from approximate to 40 to approximate to 1000 nm. DC conductivity of blend improves on irradiation. One-dimensional variable range hopping conduction mechanism is dominating in the irradiated blend. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 623-633, 2011″
“We propose a polariton hyperparametric oscillator (PHO) based on a semiconductor photonic dot at the micro/nano scale. By theoretical derivations and numerical calculations, we find that the PHO not only amplify weak signals like general large-planar polariton amplifiers, but also depress strong signals unusually. The coexistence of such signal amplification and depression can cause a stable signal emission being almost independent of the excitation instabilities in the strong-excitation regime.
