Heparan sulfate (HS), a long linear polysaccharide, is implicated in various steps of tumorigenesis, including angiogenesis. We successfully interfered with HS biosynthesis using a peracetylated 4-deoxy analogue of the HS constituent GlcNAc and studied the ...
Abstract The Wnt/β-catenin signalling and autophagy pathways each play important roles during development, adult tissue homeostasis and tumorigenesis. Here we identify the Wnt/β-catenin signalling pathway as a negative regulator of both basal and stress-in ...
Tungsten carbide (WC) and cobalt (Co) are constituents of hard metals and are used for the production of extremely hard tools. Previous studies have identified greater cytotoxic potential of WC-based nanopartides if particles contained Co. The aim of this ...
Intestinal homeostasis is achieved, in part, by the integration of a complex set of mechanisms that eliminate pathogens and tolerate the indigenous microbiota. Drosophila melanogaster feeds on microorganism-enriched matter and therefore has developed effic ...
This study aimed at comparing the photocatalytic efficiencies of various TiO2 based photocatalysts for phenol degradation and bacteria inactivation under illumination with visible light. Commercial undoped anatase and rutile (both from Aldrich), Aeroxide P ...
Aim: Ultrasmall superparamagnetic iron oxide nanoparticles (USPIO-NPs) are under development for imaging and drug delivery; however, their interaction with human blood brain barrier models is not known. Materials & Methods: The uptake, reactive oxygen spec ...
Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool to investigate large molecules. Miniaturized microchips, as a goal of ‘Lab-on-chip’, allow various integrated analysis quickly. The coupling of functional microchips and ESI-MS is capabl ...
We theoretically investigate the dependence of the different parameters of an optical biosensor for the detection of Hydrogen peroxide (H2O2) based on absorption enhancement of Cytochrome c molecules near gold nanoparticles. H2O2 is a major reactive oxygen ...

The self-assembly of the oppositely charged watersoluble porphyrins, cobalt tetramethylpyridinium porphyrin (CoTMPyP4+) and cobalt tetrasulphonatophenyl porphyrin (CoTPPS4−), at the interface with an organic solvent to form molecular “rafts”, provides an e ...
Aims Statins protect against cardiovascular-related mortality but induce skeletal muscle toxicity. To investigate mechanisms of statins, we tested the hypothesis that statins optimized cardiac mitochondrial function but impaired vulnerable skeletal muscle ...
