Discovery of a low order drug-cell response surface for applications in personalized medicine

Hubert van den Bergh, Patrycja Nowak-Sliwinska

The cell is a complex system involving numerous components, which may often interact in a non-linear dynamic manner. Diseases at the cellular level are thus likely to involve multiple cellular constituents and pathways. As some drugs, or drug combinations, ...

Real-time, in vivo measurement of tissular pO(2) through the delayed fluorescence of endogenous protoporphyrin IX during photodynamic therapy

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska, Anna Maria Novello, Cédric Xavier Paulou

Tissular oxygen concentration plays a key role during photodynamic therapy (PDT). Therefore, monitoring its local oxygen partial pressure (pO(2)) may help predict and/or control the outcome of a PDT treatment. The first real-time, in vivo measurements of t ...

In vitro and in vivo studies of new photoluminescent oxygen sensors for non-invasive intravascular pO 2 measurements

Hubert van den Bergh, Georges Wagnières, Patrycja Nowak-Sliwinska

The concentration of oxygen and its rate of consumption are important factors playing a role in PDT and radiotherapy. One of the methods for measuring the tissular oxygen partial pressure (pO 2) is based on the use of luminophores presenting an oxygen-depe ...

Towards Light-Activated Ruthenium-Arene (RAPTA-Type) Prodrug Candidates

Paul Joseph Dyson, Rosario Scopelliti, Patrycja Nowak-Sliwinska, Felix Daniel Bobbink, Anna Katherine Renfrew

Cancer is currently one of the deadliest diseases worldwide. Based on the high incidence of this disease, the side effects associated with current chemotherapies and the appearance of drug resistance, considerable efforts have been directed towards the dev ...

Low-dose angiostatic tyrosine kinase inhibitors improve photodynamic therapy for cancer: lack of vascular normalization

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Andrea Brett Gasser, Débora Bonvin

Photodynamic therapy (PDT) is an effective clinical treatment for a number of different cancers. PDT can induce hypoxia and inflammation, pro-angiogenic side effects, which may counteract its angio-occlusive mechanism. The combination of PDT with anti-angi ...

Functional consequences of prolactin signaling in endothelial cells: a potential link with angiogenesis in pathophysiology?

Patrycja Nowak-Sliwinska

Prolactin is best known as the polypeptide anterior pituitary hormone, which regulates the development of the mammary gland. However, it became clear over the last decade that prolactin contributes to a broad range of pathologies, including breast cancer. ...

Helical equilibrium magnetohydrodynamic flow effects on the stability properties of low-n ideal external-infernal modes in weak shear tokamak configurations

Jonathan Graves, Wilfred Anthony Cooper, Patrycja Nowak-Sliwinska, Daniele Brunetti, Alberto Mariani

The impact of equilibrium helical flows on the stability properties of low shear tokamak plasmas is assessed. The corrections due to such helical flow to the equilibrium profiles (mass density, pressure, Shafranov shift, magnetic fluxes) are computed by mi ...
