On-line preconcentration of mercury by sorption on an anion-exchange resin loaded with 1,5-bis[(2-pyridyl)-3-sulphophenyl methylene] thiocarbonohydrazide and determination by cold-vapour inductively coupled plasma atomic emission.
Talanta 46 , 1095-1105, (1998) 1,5-Bis[(2-pyridyl)-3-sulphophenyl methylene] thiocarbonohydrazide (PSTH) immobilized on an anion-exchange resin (Dowex) has been used for the on-line preconcentration of mercury from biological samples and waters prior to its determination by inductively cou... |

On-line ion-exchange preconcentration and determination of traces of platinum by electrothermal atomic absorption spectrometry.
Anal. Bioanal. Chem 375 , 1229-1233, (2003) A method to determine trace amounts of platinum in different samples based on electrothermal atomic absorption spectrometry is described. The preconcentration step is performed on a chelating resin microcolumn [1,5-bis(2-pyridyl)-3-sulfophenyl methylene thioc... |

Synthesis of new hypoxia markers EF1 and [18F]-EF1.
Appl. Radiat. Isot. 51(6) , 643-50, (1999) We report on the preparation of a hypoxia marker 2-(2-nitroimidazol-1[H]-yl)-N-(3-fluoropropyl)acetamide (EF1) and its 18F analog, 2-(2-nitroimidazol-1[H]-yl)-N- (3-[18F]fluoropropyl)acetamide ([18F]-EF1). Two methods for the preparation of 3-fluoropropylamin... |

Borate complexes of x-ray iodinated contrast agents: characterization and sorption studies for their removal from aqueous media.
J. Hazard. Mater. 205-206 , 10-16, (2012) Iodinated contrast media (ICM) are persistent and ubiquitous water pollutants. Because of their high water solubility and biochemical stability, their phase-separation and recovery from the aquatic environment is very difficult. Here, borate was chosen as a c... |

Apolipoprotein E isoform-specific disruption of phosphoinositide hydrolysis: protection by estrogen and glutathione.
FEBS Lett. 504(1-2) , 45-9, (2001) The mechanism(s) by which the E4 isoform of apolipoprotein E (apoE4) influences Alzheimer's disease (AD) are not fully known. We report that apoE4, but not apoE3, disrupts carbachol-stimulated phosphoinositide (PI) hydrolysis in SH-SY5Y neuroblastoma cells. C... |

Glucose delivery is a major determinant of glucose utilisation in the ischemic myocardium with a residual coronary flow.
Cardiovasc. Res. 39(2) , 381-92, (1998) Experimental data from isolated rat hearts suggest that glycolysis in severe myocardial ischemia is inhibited by accumulation of glycolytic metabolites. In contrast, positron emission tomography (PET) in patients with myocardial ischemia records a 'mismatch' ... |

Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger.
Forensic Sci. Int. 174(2-3) , 239-43, (2008) The Meisenheimer anions formed from TNT in KOH solutions in alcohol or acetone were used in screening tests for TNT among possible nitro-explosives. The same reaction was used for the spectrophotometric assay of TNT in soil by CRREL (Cold Regions Research & E... |

Regulation of pantothenate kinase from various tissues of the rat.
FEBS Lett. 190(2) , 293-6, (1985) The relative tissue activities of pantothenate kinase range from 1 to 5 nmol . min-1 . g-1 wet wt for heart, brain, kidney, and liver. The enzyme partially purified from each tissue is inhibited by CoA, but there is a 10-fold greater potency of inhibition of ... |
