2 GeV Au ions. Flux oscillations are spontaneously excited after exposing the sample to a steady magnetic field near the order-disorder vortex phase transition line. The oscillations originate at the border between the irradiated and nonirradiated parts of the sample and propagate into the nonirradiated region toward the sample edge. Previously reported flux oscillations were observed in the vicinity of undefined

defects in as grown Bi2Sr2CaCu2O8+delta crystals. Observation of spontaneous oscillations in partially irradiated samples present the first attempt to generate such oscillations in a controlled manner. (C) 2009 P5091 American Institute of Physics. [DOI: 10.1063/1.3068647]“
“A new triterpene saponin (1) was isolated from a methanol extract of Swartzia apetala Raddi var. glabra, together with the flavonoids mauritianin (2), kaempferol (3) and the triterpene saponin -D-glucopyranosyl 3-hydroxy-olean-12-en-28-oate (4). These

compounds were characterised on the basis of their spectral data, mainly one-dimension (1D; H-1, C-13, APT) and two-dimension (2D; H-1-H-1-COSY, HMQC and HMBC) nuclear magnetic resonance (NMR) and HR-ESI-MS, and comparison with values in the literature. The analysis by HR-ESI-MS showed a mass compatible with that of triterpene saponin 1. This proposal was supported by molecular modelling. LC-HR-ESI-MS experiment was also Vorinostat used to evaluate the purity of 1 and allowed to speculate about the possibility of the presence of 5 in very small quantity. The extract and four compounds were assayed for antifungal activity against nine strains of Candida spp.”
“To utilize fish waste, black pomfret, Parastromateus niger viscera was analysed for its proximate and amino acid composition followed

by hydrolysis using various proteases to extract antioxidant peptide. Antioxidant activities of the crude hydrolysate was evaluated using DPPH (54%), metal chelating (78.6%) at a concentration of 1 mg/mL, whereas this website the reducing power assay was done with different concentration (0.5-2.5 mg/mL) and the activity also increased with increasing concentration (0.021-0.068). Furthermore, the hydrolysate was purified by diethylaminoethyl (DEAE) ion-exchange and Sephadex G-25 gel filtration chromatography. Finally, the purified peptide had a mass of 701.9 Da, and the amino acid sequence was identified as Ala-Met-Thr-Gly-Leu-Glu-Ala using electrospray ionization-tandem mass spectrometry (ESI-MS/MS). Moreover, the protection ability of the peptide toward hydroxyl radical-induced oxidative DNA damage and inhibiting lipid peroxidation was evaluated and compared with natural antioxidant alpha-tocopherol.”
