05, p < 0.001) increase

in pain threshold both in hotplate and tail immersion methods in a dose dependent manner. The results were comparable to the reference standard Nalbuphine. In acetic acid-induced writhing test, the extract (500 mg/kg) produced a maximum of 75.9% inhibition (p < 0.001) of writhing reaction compared to the reference drug Diclofenac-Na (10 mg/kg) (78.1%). These results suggest FDA-approved Drug Library that the extract possesses strong CNS depressant and analgesic activity in mice.”
“In the present work we have studied the effect of 190 MeV Ag ion irradiation on the structural, electrical, and magnetic properties of LaFe(1-x)Ni(x)O(3) (x = 0.3 and 0.4) thin films. The films were grown on LaAlO(3) < 001 > oriented substrates using pulsed laser deposition technique. The pristine and irradiated samples were investigated using x-ray diffraction, temperature dependent resistivity, and magnetic measurements. The x-ray diffraction patterns of the irradiated films show that the lattice of the composition strain relaxed with enhanced c-axis orientation. The temperature

dependence of the resistivity indicates that all the films (pristine and irradiated) exhibit semiconducting behavior for entire studied temperature range (80-300 K). The pristine and irradiated samples show the activated variable see more range hopping behavior throughout the studied temperature range. The magnetization hysteresis measurements show ferromagnetic behavior at 300 K for all samples. The results are explained on the basis of the close interplay between the electrical and the magnetic

properties. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3400036]“
“Fibrous membranes of cellulose acetate (CA), poly(vinyl pyrrolidone) (PVP) and composite membranes of these polymers, were obtained by the electrospinning method. Using systematic CT99021 method, the optimal conditions for preparation of fibrous membranes were found. Both CA and PVP a concentration of 8% weight was found. The CA was dissolved in a acetone:- water solution, volume ratio 80 : 20 and the PVP is dissolved in ethanol:water solution, ratio volume 85 : 15. The flow rate for both polymers was 1.5 mL h(-1). The same applied voltage value and the distance between the needle and collection plate were for polymer both, 15 kV and 15 cm respectively. The morphology of fibrous membranes and composite membranes were evaluated by scanning electron microscopy (SEM). The CA fibers showed ribon morphology, while the PVP fibers were cilindric, in both cases with diameters in the micrometer range. Thermogravimetric analysis showed that CA had a complete degradation to 445 degrees C, while the fibrous membranes PVP required a value of temperature for degradation of up to 571 degrees C. Fibrous composite membrane PVP/CA/PVP shows a higher value of strain at break (%), and a lower value of tensile strength (MPa) compared to CA/PVP/CA. (C) 2010 Wiley Periodicals, Inc.
