Ionizing radiation (IR) triggers mitochondrial overproduction of H2O2 and accumulation of lipid hydroperoxides leading to the induction of apoptotic and necroptotic cell death pathways. Given the high catalytic efficiency of the seleno-enzyme glutathione peroxidase (Gpx) toward reduction of lipid hydroperoxides and H2O2, we tested the potential of mitochondria-targeted derivatives of ebselen to...

In the mol-ecule of the title compound, C(7)H(15)N(3)O, the central C atom is surrounded in a nearly ideal trigonal-planar geometry by three N atoms. The C-N bond lengths in the CN(3) unit are 1.3353 (13), 1.3463 (12) and 1.3541 (13) Å, indicating an inter-mediate character between a single and a double bond for each C-N bond. The bonds between the N atoms and the terminal C-methyl groups all h...

The chemical constituents and biological activities of the terrestrial Aspergillus flavipes MM2 isolated from Egyptian rice hulls are reported. Seven bioactive compounds were obtained, of which one sterol: ergosterol (1), four butyrolactones: butyrolactone I (2), aspulvinone H (3), butyrolactone-V (6) and 4,4'-diydroxypulvinone (7), along with 6-methylsalicylic acid (4) and the cyclopentenone a...

BACKGROUND C(60) is a highly insoluble nanoparticle that can form colloidal suspended aggregates in water, which may lead to environmental exposure in aquatic organisms. Previous research has indicated toxicity from C(60) aggregate; however, effects could be because of tetrahydrofuran (THF) vehicle used to prepare aggregates. OBJECTIVE Our goal was to investigate changes in survival and gene ...
