Synthesis and evaluation of candidate PET radioligands for corticotropin-releasing factor type-1 receptors.
Nucl. Med. Biol. 41(6) , 524-35, (2014) A radioligand for measuring the density of corticotropin-releasing factor subtype-1 receptors (CRF1 receptors) in living animal and human brain with positron emission tomography (PET) would be a useful tool for neuropsychiatric investigations and the developm... |

Improved quality control of [18F]fluoromethylcholine.
Nucl. Med. Biol. 38(8) , 1143-8, (2011) With respect to the broad application of [(18)F-methyl]fluorocholine (FCH), there is a need for a safe, but also efficient and convenient way for routine quality control of FCH. Therefore, a GC- method should be developed and validated which allows the simult... |

Dimethylselenide as a probe for reactions of halogenated alkoxyl radicals in aqueous solution. Degradation of dichloro- and dibromomethane.
J. Phys. Chem. A 112(26) , 5908-16, (2008) Using pulse radiolysis and steady-state gamma-radiolysis techniques, it has been established that, in air-saturated aqueous solutions, peroxyl radicals CH 2HalOO (*) (Hal = halogen) derived from CH 2Cl 2 and CH 2Br 2 react with dimethyl selenide (Me 2Se), wit... |

Episodic trihalomethane species and levels in tap water at a start of operation of advanced treatment in Osaka Prefectural water supplies.
Bull. Environ. Contam. Toxicol. 83(5) , 674-6, (2009) Dramatic changes in trihalomethanes of tap water caused by decreasing the chlorine dose from to break-point to zero at a pre-chlorination could be found during several years from starting the advanced treatment in Osaka Prefectural water utilities (from 1998 ... |

[Research concerning rutin semisynthetic derivatives. Synthesis, physico-chemical and microbiological characterisation of some new rutin-isoniazid derivatives].
Rev. Med. Chir. Soc. Med. Nat. Iasi. 112(1) , 249-52, (2008) Isoniazid is one of the most used antituberculosis drugs, but its toxicity is high. In this study, four derivatives of rutin and isoniazid were prepared and their antibacterial and antimycotic activities were investigated.Synthesis of these compounds started ... |

A method for carbon stable isotope analysis of methyl halides and chlorofluorocarbons at pptv concentrations.
Rapid Commun. Mass Spectrom. 19(3) , 337-42, (2005) A pre-concentration system has been validated for use with a gas chromatography/mass spectrometry/isotope ratio mass spectrometer (GC/MS/IRMS) to determine ambient air (13)C/(12)C ratios for methyl halides (MeCl and MeBr) and chlorofluorocarbons (CFCs). The i... |

Predicting vehicle effects on the dermal absorption of halogenated methanes using physiologically based modeling.
Toxicol. Sci. 48(2) , 180-8, (1999) Occupational and environmental settings present opportunities for humans to come into contact with a variety of chemicals via the dermal route. The chemicals contacting the skin are likely to be diluted with a vehicle or present as a component of a mixture. I... |

Do vesicle cells of the red alga Asparagopsis (Falkenbergia stage) play a role in bromocarbon production?
Chemosphere 52(2) , 471-5, (2003) The Rhodophyceae (red algae) are an established source of volatile halocarbons in the marine environment. Some species in the Bonnemaisoniaceae have been reported to contain large amounts of halogens in structures referred to as vesicle cells, suggesting invo... |

Alkyltransferase-mediated toxicity of bis-electrophiles in mammalian cells.
Mutat. Res. 684(1-2) , 35-42, (2010) The primary function of O(6)-alkylguanine-DNA alkyltransferase (AGT) is to maintain genomic integrity in the face of damage by both endogenous and exogenous alkylating agents. However, paradoxically, bacterial and mammalian AGTs have been shown to increase cy... |
