Sedimentation of macroscopic rigid knots and its relation to gel electrophoretic mobility of DNA knots

Giovanni Dietler, Cédric Weber, Andrzej Stasiak, Mathias Carlen

We address the general question of the extent to which the hydrodynamic behaviour of microscopic freely fluctuating objects can be reproduced by macrosopic rigid objects. In particular, we compare the sedimentation speeds of knotted DNA molecules undergoin ...

Coupling Isoelectric Focusing Gel Electrophoresis to Mass Spectrometry by Electrostatic Spray Ionisation

Hubert Girault, Liang Qiao, Elena Tobolkina

Gel electrophoresis has been used for decades as a high-resolution separation technique for proteins and protein isomers, but limited in the coupling with MS because of low throughput and poor automaticity compared with LC-MS. In this work, we have develop ...

The molecular mechanisms of antimetastatic ruthenium compounds explored through DIGE proteomics

Paul Joseph Dyson, Angela Casini

DIGE (difference in gel electrophoresis) proteomics is exploited here to gain insight into the molecular mechanisms of two established ruthenium-based antimetastatic agents, namely trans-[tetrachloro (DMSO) (imidazole)ruthenate(III)] (NAMI-A) and [Ru(eta(6 ...

Densification of C-S-H Measured by H-1 NMR Relaxometry

Karen Scrivener, Arnaud Charles Albert Muller

The nanoscale morphology of, and pore water interactions in, calcium silicate hydrate (C-S-H), the active component of cement, remain uncertain. H-1 nuclear magnetic resonance (NMR) can fully characterize the nanoporosity of C-S-H in as-prepared material w ...

DNA delivery with hyperbranched polylysine: A comparative study with linear and dendritic polylysine

Harm-Anton Klok, Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Yashas Rajendra, Zuzana Kadlecova

PEI and polylysine are among the most investigated synthetic polymeric carriers for DNA delivery. Apart from their practical use, these 2 classes of polymers are also of interest from a fundamental point of view as they both can be prepared in different ar ...

Impact of microbial Mn oxidation on the remobilization of bioreduced U(IV)

Rizlan Bernier-Latmani, Kelly Lee Plathe

Effects of Mn redox cycling on the stability of bioreduced U(IV) are evaluated here. U(VI) can be biologically reduced to less soluble U(IV) species and the stimulation of biological activity to that end is a salient remediation strategy; however, the stab ...

The effect of crowding and confinement: a comparison of Yfh1 stability in different environments

Paolo De Los Rios

Crowding and confinement can affect protein stability, favouring the more compact species amongst the folded and unfolded conformations. An unbiased assessment of the relative efficacy of crowded and confined environments has been hampered so far by the pa ...

Mitonuclear protein imbalance as a conserved longevity mechanism

Johan Auwerx, Graham Knott, Laurent Mouchiroud, Richardus Houtkooper, Dongryeol Ryu, Elena Katsyuba, Norman Lionel Moullan

Longevity is regulated by a network of closely linked metabolic systems. We used a combination of mouse population genetics and RNA interference in Caenorhabditis elegans to identify mitochondrial ribosomal protein S5 (Mrps5) and other mitochondrial riboso ...

Self-Cleaning Antireflective Optical Coatings

Morgan Mertens Stefik, Stefan Guldin

Low-cost antireflection coatings (ARCs) on large optical surfaces are an ingredient-technology for high-performance solar cells. While nanoporous thin films that meet the zero-reflectance conditions on transparent substrates can be cheaply manufactured, th ...

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 ...
