Development of an accurate and high-throughput methodology for structural comprehension of chlorophylls derivatives. (I) Phytylated derivatives.
J. Chromatogr. A. 1406 , 99-108, (2015) Phytylated chlorophyll derivatives undergo specific oxidative reactions through the natural metabolism or during food processing or storage, and consequently pyro-, 13(2)-hydroxy-, 15(1)-hydroxy-lactone chlorophylls, and pheophytins (a and b) are originated. ... |

The inhibitory effect of selenium nanoparticles on protein glycation in vitro.
Nanotechnology 26(14) , 145703, (2015) Selenium nanoparticles (Se NPs) possess well-known excellent biological activities and low toxicity, and have been employed for numerous applications except as inhibitors to protein glycation. Herein, the present study is carried out to investigate the inhibi... |

Thiol-mediated multiple mechanisms centered on selenodiglutathione determine selenium cytotoxicity against MCF-7 cancer cells.
J. Biol. Inorg. Chem. 20 , 687-94, (2015) Selenium (Se) is an essential antioxidative micronutrient but can exert cancer-selective cytotoxicity if the nutritional levels are too high. Selenodiglutathione (GSSeSG) is a primary Se metabolite conjugated with two glutathione (GSH) moieties. GSSeSG has be... |

Regio- and stereoselective selenium dioxide allylic oxidation of (E)-dialkyl alkylidenesuccinates to (Z)-allylic alcohols: synthesis of natural and unnatural butenolides.
Org. Biomol. Chem. 9 , 6312-6322, (2011) The first SeO(2) induced (Z)-selective allylic alcohol formation of dialkyl alkylidenesuccinates has been demonstrated to accomplish one-step syntheses of several essential butenolides and fused butenolides via an unusual E- to Z- carbon-carbon double bond is... |

CD95 promotes metastatic spread via Sck in pancreatic ductal adenocarcinoma.
Cell Death Differ. 22 , 1192-202, (2015) Cancer stem cells (CSCs) have been implicated in the initiation and maintenance of tumour growth as well as metastasis. Recent reports link stemness to epithelial-mesenchymal transition (EMT) in cancer. However, there is still little knowledge about the molec... |

Size- and shape-controlled synthesis of ZnSe nanocrystals using SeO2 as selenium precursor.
Dalton Trans. 39(47) , 11432-8, (2010) Here we report a low-cost and "green" phosphine-free route for the size- and shape-controlled synthesis of high-quality zinc blende (cubic) ZnSe nanocrystals. To avoid the use of expensive and toxic solvents such as trioctylphosphine (TOP) or tributylphosphin... |

Differential patterns of accumulation and depuration of dietary selenium and vanadium during metamorphosis in the Gray Treefrog (Hyla versicolor).
Arch. Environ. Contam. Toxicol. 60(2) , 336-42, (2011) Selenium (Se) and vanadium (V) are contaminants commonly found in aquatic systems affected by wastes derived from fossil fuels. To examine their effects on a widely distributed species of amphibian, we exposed gray tree frogs (Hyla versicolor) to Se (as SeO₂)... |

Configuration interaction study of the electronic states and spectroscopic properties of selenium monoxide.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 89 , 160-7, (2012) The electronic spectrum of the selenium monoxide (SeO) molecule has been studied theoretically by using ab initio based multireference singles and doubles configuration interaction (MRDCI) methodology, which includes relativistic effective core potentials (RE... |
