Determination of selenium and its compounds in marine organisms.
J. Trace Elem. Med. Biol. 29 , 91-8, (2015) In this study, we investigate the type and quantity of selenium compounds in fish and marine organisms, using ion-pair reversed phase LC–ICP-MS, developed and applied for the analysis of Atlantic cod, Atlantic salmon, Greenland halibut, Atlantic herring, blue... |

Influence of Dietary Selenium Species on Selenoamino Acid Levels in Rainbow Trout.
J. Agric. Food Chem. 63 , 6484-92, (2015) Two forms of selenium (Se) supplementation of fish feeds were compared in two different basal diets. A 12-week feeding trial was performed with rainbow trout fry using either a plant-based or a fish meal-based diet. Se yeast and selenite were used for Se supp... |

Antitumor activity of an enzyme prodrug therapy targeted to the breast tumor vasculature.
Cancer Invest. 31(8) , 505-10, (2013) The L-methioninase-annexin V/selenomethionine enzyme prodrug system, designed to target the tumor vasculature and release the methylselenol anticancer drug in the tumor, was tested in mice with implanted MBA-MB-231 breast tumors. This therapy was able to caus... |

Dietary selenomethionine exposure alters swimming performance, metabolic capacity and energy homeostasis in juvenile fathead minnow.
Aquat. Toxicol. 155 , 91-100, (2014) Selenium (Se) is known to cause chronic toxicity in aquatic species. In particular, dietary exposure of fish to selenomethionine (SeMet), the primary form of Se in the diet, is of concern. Recent studies suggest that chronic exposure to elevated dietary SeMet... |

Identification of selenium-containing proteins in HEK 293 kidney cells using multiple chromatographies, LC-ICPMS and nano-LC-ESIMS.
Talanta 114 , 25-31, (2013) Our previous studies using HeLa and HEK 293 cells demonstrated that selenomethionine, SeMet, exerts more of an antagonistic effect on arsenic than other selenium species. These studies attributed the antagonistic effect of SeMet to decreased levels of reactiv... |

In vitro and in vivo percutaneous absorption of seleno-L-methionine, an antioxidant agent, and other selenium species.
Acta Pharmacol. Sin. 32 , 1181-1190, (2011) To investigate the in vitro and in vivo percutaneous absorption of seleno-L-methionine (Se-L-M), an ultraviolet (UV)-protecting agent, from aqueous solutions.Aqueous solutions of Se-L-M were prepared in pH 4, 8, and 10.8 buffers. The pH 8 buffer contained 30%... |

Selenium supplementation protects trophoblast cells from oxidative stress
Placenta 33(12) , 1012-9, (2012) Oxidative stress is a key feature in the pathogenesis of pre-eclampsia and antioxidants have been proposed as a potential therapy in the treatment of this important complication of pregnancy. In this report selenium supplementation was used to up-regulate the... |

Selenium species and their distribution in freshwater fish from Argentina.
Biol. Trace Elem. Res. 151(2) , 240-6, (2013) The distribution and speciation of selenium (Se) in freshwater fish (muscle and liver tissue) from lakes in Argentina was investigated. Three introduced species, brown trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fonti... |

Effects of dietary selenium supplementation on tissue selenium distribution and glutathione peroxidase activity in Chinese Ring necked Pheasants.
Animal 7(4) , 562-70, (2013) The objective of this study was to determine the concentration of total selenium (Se) and the proportions of total Se comprised as selenomethionine (SeMet) and selenocysteine (SeCys) in the postmortem tissues of female pheasants (Phasianus Colchicus Torquator... |

Bioavailability, toxicity and biotransformation of selenium in midge (Chironomus dilutus) larvae exposed via water or diet to elemental selenium particles, selenite, or selenized algae.
Environ. Sci. Technol. 47(1) , 584-92, (2013) Elemental selenium (Se) is generally considered to be biologically inert due to its insolubility in water. It is a common form of Se in sediment near uranium mining and milling operations in northern Saskatchewan, Canada. Nanosized particles of many materials... |
