J Phys Chem A. 2015 Apr 09;119(14):3366-74. doi: 10.1021/jp512599e. Epub 2015 Mar 30.

The gas-phase complex UO2(TMOGA)2(2+) (TMOGA = tetramethyl-3-oxa-glutaramide) prepared by electrospray ionization was characterized by infrared multiphoton dissociation (IRMPD) spectroscopy. The IRMPD spectrum from 700-1800 cm(-1) was interpreted using a computational study based on density functional theory. The predicted vibrational...

Structures of Fluoranthene Reagent Anions Used in Electron Transfer Dissociation and Proton Transfer Reaction Tandem Mass Spectrometry.

Hyperleukocytosis, defined as a peripheral leukocyte count ≥ 100x109/L, is seen in 5-20% of newly diagnosed cases of childhood leukemia and is a poor prognostic factor. In this study, we aimed to examine the presenting clinical and laboratory features,...

1,1-carbozirconation: unusual reaction of an alkyne with a methyl zirconocene cation and subsequent frustrated lewis pair like reactivity.

Angewandte Chemie (International ed. in English)

Xu X, Kehr G, Daniliuc CG, Erker G.
PMID: 24222316
Angew Chem Int Ed Engl. 2013 Dec 16;52(51):13629-32. doi: 10.1002/anie.201307493. Epub 2013 Nov 12.

Boron chemistry without the boron: In a reaction analogous to 1,1-carboboration, [Cp*2 ZrCH3 ](+) reacts with diphenylphosphino(trimethylsilyl)acetylene by 1,1-carbozirconation to give a vicinal [Zr](+) /P system. Like B/P frustrated Lewis pairs, the [Zr](+) /P system undergoes 1,2-addition to unsaturated...

The dog prostate cancer (DPC-1) model: a reliable tool for molecular imaging of prostate tumors and metastases.

EJNMMI research

Chevalier S, Moffett S, Turcotte E, Luz M, Chauvette L, Derbekyan V, Scarlata E, Zouanat F, Aprikian AG, Anidjar M.
PMID: 26714499

BACKGROUND: Clinical applicability of newly discovered reagents for molecular imaging is hampered by the lack of translational models. As the dog prostate cancer (DPC-1) model recapitulates in dogs the natural history of prostate cancer in man, we tested the...
