The picroside I and II content in various plant parts of P. kurrooa collected from different altitudes, viz. Sonemarg (2,740 m a.s.l.), Tangmarg (2,690 m a.s.l.), and Pulwama (1,630 m a.s.l.)

in the north-western Kashmir Himalayas was analyzed by HPLC. A considerable degree of variation in picroside content was observed. Picroside I and II was highest in populations collected from Sonemarg followed by Tangmarg, suggesting that picroside click here accumulation is directly correlated with altitudinal change. More picroside I was found in the rhizome and roots of the Pulwama population as compared to Tangmarg samples, whereas the quantity of Picroside II was reduced in plants from Pulwama compared to the Tangmarg population, suggesting that cultivation of P. kurroa at lower altitude reduces the picroside content. The quantities of picrosides also varied spatially, being highest in rhizome followed by roots, inflorescence and leaves in the populations from all three locations. The study concludes that picroside I and II accumulation depends on altitude, which could help in the selection and collection of superior genotypes with

uniform effects for utilization by the pharmaceutical industry.”
“We present the experimental realization and characterization of a broadband acoustic metamaterial with strongly anisotropic KU55933 effective mass density. The metamaterial is composed of arrays of solid inclusions in an air background, and the anisotropy is controlled by the rotational asymmetry of these inclusions. Transmission and reflection measurements inside a one-dimensional waveguide are used to extract the relevant components of the effective density tensor together with the effective bulk modulus of the metamaterial. Its broadband anisotropy is demonstrated by measurements that span 500-3000 Hz. Excellent agreement between these

measurements and numerical simulations confirms Fer-1 chemical structure the accuracy of the design approach. (C) 2011 American Institute of Physics. [doi:10.1063/1.3552990]“
“The present study is aimed at evaluating the efficacy and safety of long-acting risperidone on early onset schizophrenia in adolescent patients. A total of 31 adolescent patients (13 – 18 years) with schizophrenia met the DSM-IV-TR criteria for schizophrenia and their symptoms were stable when orally taking risperidone or olanzapine. They were admitted into a 24 week, open-label study on the long-acting risperidone. Risperidone was administered every 2 weeks at a dose of 25, 37.5 and up to a maximum dose of 50 mg. The Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impressions (CGI) and the Extrapyramidal symptom rating scale (ESRS) were used to assess the improvement in the symptoms.
