Poly(3,4-ethylenedioxythiophene) (PEDOT) plays a key role in the field of electrically conducting materials, despite its poor solubility and processability. Various molecules and polymers carrying sulfonic groups can be used to enhance PEDOT's electrical conductivity. Among all, sulfonated polyarylether sulfone (SPAES)

The recent introduction of a dynamic nuclear polarisation technique has permitted noninvasive imaging of tumour cell metabolism in vivo following intravenous administration of (13)C-labelled cell substrates. Changes in hyperpolarised [1-(13)C]pyruvate and [1,4-(13)C(2)]fumarate metabolism were evaluated in both MDA-MB-231 cells and

Calcium dobesilate is an angio-protective agent that has positive effects on hemorheological parameters. It decreases blood and plasma viscosity, thrombocyte aggregation, and microvascular hyperpermeability. It is an antioxidant that increases endothelial-derived vasodilator substance secretion. In this experimental study, the effects
