Abstract
Atrial fibrillation (AF) is an important cause of morbidity and mortality after cardiac surgery. The pathogenesis of AF appears to be multifactorial but little is known about the cause-effect relationship of substrate modifications with the onset of the arrhythmia. With the use of modern proteomics,...

Abstract
These results clearly demonstrate that MMP-9 is elevated in CSF of dogs with visceral leishmaniasis (VL). Although these results are preliminary, they suggest that MMP-9 might play a role in disruption of blood-brain barrier and/or blood-CSF barrier. While the presence of MMPs in CSF is not a condit...

Abstract
We investigated the gradual disassembly of the AcrB trimer and bound DARPin ligands in dependence on laser intensity in solution. At low laser intensity, the release of the detergent molecule micelle from the AcrB/DARPin complex was observed. By increasing laser intensity, dimeric and monomeric AcrB...

Shotgun proteomics originated as a strategy to identify proteins in complex protein mixtures, but it is also possible to obtain information on relative quantitation with some adjustments to the procedure. After protein digestion, the resulting peptide mixture is labelled with isobaric tags. Then, la...

We quantified protein vicinal dithiols within mammalian mitochondria using the vicinal dithiol-specific reagent phenylarsine oxide (PAO). We found 5-15% of thiols exposed on mitochondrial proteins were vicinal dithiols and that these thiols were particularly sensitive to oxidation by hydrogen peroxi...

We find that for low fields most DNA molecules follow tortuous paths through the gels, at an angle up to 90 degrees from the field direction, while some molecules find paths along the field lines. In high fields, virtually all of the DNA molecules follow the field lines. In many cases, the molecules...
