Quantification of the neurochemical profile using simulated macromolecule resonances at 3 T

Rolf Gruetter, Lijing Xin, Cristina Ramona Cudalbu, Benoît Schaller

The broad resonances underlying the entire (1) H NMR spectrum of the brain, ascribed to macromolecules, can influence metabolite quantification. At the intermediate field strength of 3 T, distinct approaches for the determination of the macromolecule signa ...

Characterization of Silver Nanoparticle Products Using Asymmetric Flow Field Flow Fractionation with a Multidetector Approach - a Comparison to Transmission Electron Microscopy and Batch Dynamic Light Scattering

Christian Ludwig, Andrea Ulrich, Harald Hagendorfer

Due to the already prevalent and increasing use of silver-nanoparticle (Ag-NP) products and the raised concerns in particular for the aquatic environment, analytical techniques for the characterization of such products are of need. However, because Ag-NP p ...

Encapsulation of Huh-7 cells within alginate-poly(ethylene glycol) hybrid microspheres

Jutta Christine Wandrey, Redouan Mahou

Novel calcium alginate poly(ethylene glycol) hybrid microspheres (Ca-alg-PEG) were developed and evaluated as potentially suitable materials for cell microencapsulation. Grafting 5-13% of the backbone units of sodium alginate (Na-alg) with alpha-amine-omeg ...

Combination of metallomics and proteomics to study the effects of the metallodrug RAPTA-T on human cancer cells

Paul Joseph Dyson, Michael Groessl

An approach to characterize the interactions of RAPTA-T, a novel ruthenium-based anticancer drug candidate with intriguing antimetastatic properties, with human ovarian cancer cells in vitro is described. The distribution profile of the metallodrug within ...
