“In this study, the feasibility of ultra-dry storage of Barbados nut (Jatropha curcas L.) seeds was investigated. The J. curcas seeds were dehydrated to six
different moisture contents (1.33-6.98%) and stored at ambient temperature for 3 yr. Then, the indices related to seed vigor were measured. To explore the mechanism of ultra-dry storage, some physiological and biochemical indicators, including electrical conductivity (EC); contents of proline (Pro) and malondialdehyde (MDA); activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate peroxidase www.selleckchem.com/products/cobimetinib-gdc-0973-rg7420.html (APX), and glutathione reductase (GR); total soluble sugar content; and fatty acid composition, were determined. Results indicated that moisture content and prehumidification method significantly affected seed germination and vigor. The ultra-dried seeds showed a higher germination percentage than nondehydrated seeds. The germination percentage of ultra-dried seeds was negatively correlated with EC and MDA content and positively correlated with the activities of five
antioxidant enzymes. As compared with the nondehydrated seeds, the ultra-dried seeds had lower soluble sugar and higher unsaturated fatty acids contents. The moisture content of 4.06% was found to be the optimal ultra-drying treatment, which is beneficial to enhance the activity of antioxidant enzymes and reduce lipid peroxidation of cell membranes, 5-Fluoracil thereby slowing the decline in viability of J. curcas seeds.”
“An electrophoretically homogenous CA3 cost aggregate of acid trehalase, invertase and an unidentified 37-41 kDa protein was purified from Saccharomyces cerevisiae. N-terminal analysis of the protein revealed an amino acid sequence identical to that of Bgl2p (endo-beta-l,3-glucanase) of S. cerevisiae. Acid trehalase activity with co-eluted glucanase activity was observed
from late growth phase through early stationary phase. Pools with high percentage of Bgl2p corresponded with high acid trehalase activity. A BGL2 deletion strain had lower acid trehalase activity. The 37-41 kDa protein represents Bgl2p which, besides imparting glucanase activity, could also be acting as a regulator for the acid trehalase activity by association in the enzyme aggregate.”
“In the title moleclue, C(19)H(21)NO, the 4-piperidone ring adopts a chair conformation in which the two benzene rings and the methyl group attached to C atoms all have equatorial orientations. In the crystal structure, centrosymmetric dimers are formed through weak intermolecular C-H center dot center dot center dot O hydrogen bonds [the dihedral angle between the aromatic rings is 58.51 (5)degrees].”
“Our previous finding that pre-initiation treatment of indole-3-carbinol (I3C) represents a chemopreventive effect in dimethylbenz(a]anthracene (DMBA)induced mammary carcinogenesis has prompted us to test the global expression of genes at an early stage.
