Double-balloon jejunal perfusion to compare absorption of vitamin E and vitamin E acetate in healthy volunteers under maldigestion conditions

Martin Kussmann, Krisztina Nagy

BACKGROUND/OBJECTIVES: The vitamin E derivative, alpha-tocopheryl acetate, is often included in formulations used in enteral nutrition. In this respect, we compared alpha-tocopherol and alpha-tocopheryl acetate absorption under 'maldigestion' conditions, s ...

Arene ruthenium complexes with phosphinoferrocene amino acid conjugates: Synthesis, characterization and cytotoxicity

Paul Joseph Dyson, Olivier Pierre Zava

A series of heterodinuclear p-cymene ruthenium ferrocene complexes, [(eta(6)-p-MeC6H4Pri)RuCl2(Ph(2)Pfc-CONHRCO2Me-kappa P)] (R = (S)-Me: 6, R = (S)-CHMe2: 7, R = (S)-CH2OMe: 8, R = (S)-CH2SMe: 9, R = (S)-CH2CH2CO2Me: 10) have been synthesized from p-cymen ...

Biochemical Membrane Lipidomics during Drosophila Development

Françoise Gisou van der Goot Grunberg, Xue Li Guan, Ernst Hafen

Lipids play critical roles in energy homeostasis, membrane structure, and signaling. Using liquid chromatography and mass spectrometry, we provide a comprehensive semiquantification of lipids during the life cycle of Drosophila melanogaster (230 glyceropho ...

Iterative Method for Mass Spectra Recalibration via Empirical Estimation of the Mass Calibration Function for Fourier Transform Mass Spectrometry-Based Petroleomics

Yury Tsybin, Anton Kozhinov, Konstantin Zhurov

We describe a mass spectra recalibration method, which enables analysis of petroleum samples with Orbitrap FTMS. In this method, the mass calibration function is estimated on the basis of mass-to-charge ratios and abundances of internal calibrants without ...

Adsorbed and near surface structure of ionic liquids at a solid interface

Kislon Voitchovsky, Juan José Segura Sugranes

The structure of solid-ionic liquid (IL) interfaces has been characterised with unprecedented clarity by employing a range of atomic force microscopy (AFM) imaging techniques and tip pressures appropriate for the system under study. Soft contact and amplit ...

Telomerase Inhibitors from Cyanobacteria: Isolation and Synthesis of Sulfoquinovosyl Diacylglycerols from

Joachim Lingner, Gerardo Turcatti, Cyril Portmann, Damiano Banfi, Karl Gademann, Emilie Baudat, Laeticia Da Silva, Tom Woods

By using the Telospot assay, 27 different extracts of cyanobacteria were evaluated for telomerase inhibition. All extracts showed varying, but significant activity. We selected Microcystis aeruguinosa PCC 7806 to identify the active compound and a bioassay ...

Analysis of N-nitrosamines and other nitro(so) compounds in water by high-performance liquid chromatography with post-column UV photolysis/Griess reaction

Urs von Gunten, Minju Lee, Yun Ho Lee

Despite their potential carcinogenicity and probable formation during water disinfection processes, little is known about the occurrence of other nitro(so) compounds than a few specific N-nitroso compounds such as N-nitrosodimethylamine (NDMA). An analytic ...

Bifurcated Helical Core Equilibrium States in Tokamaks

Olivier Sauter, Basil Duval, Stefano Coda, Jonathan Graves, Wilfred Anthony Cooper, Holger Reimerdes, Benoît Labit, Antoine Pochelon, Trach-Minh Tran, David Pfefferlé, Federico David Halpern, Daniele Brunetti

Tokamaks with weak to moderate reversed central shear in which the minimum inverse rotational transform (safety factor) qmin is in the neighbourhood of unity can trigger bifurcated magnetohydrodynamic equilibrium states, one of which is similar to a satura ...
