Intra-Arterial Drug and Light Delivery for Photodynamic Therapy Using Visudyne (R): Implication for Atherosclerotic Plaque Treatment

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Manish Jain

Photodynamic therapy (PDT), which is based on the activation of photosensitizers with light, can be used to reduce plaque burden. We hypothesized that intra-arterial photosensitizer administration and photo-activation will lead to high and rapid accumulati ...

Optimization of drug combinations using Feedback System Control

Hubert van den Bergh, Paul Joseph Dyson, Patrycja Nowak-Sliwinska

We describe a protocol for the discovery of synergistic drug combinations for the treatment of disease. Synergistic drug combinations lead to the use of drugs at lower doses, which reduces side effects and can potentially lead to reduced drug resistance, w ...

Photobiomodulation Suppresses Alpha-Synuclein-Induced Toxicity in an AAV-Based Rat Genetic Model of Parkinson's Disease

Hubert van den Bergh, Georges Wagnières, Hilal Lashuel, Blaise Lovisa, Abid Oueslati, John Perrin

Converging lines of evidence indicate that near-infrared light treatment, also known as photobiomodulation (PBM), may exert beneficial effects and protect against cellular toxicity and degeneration in several animal models of human pathologies, including n ...

Photoactivation of lysosomally sequestered sunitinib after angiostatic treatment causes vascular occlusion and enhances tumor growth inhibition

Hubert van den Bergh, Patrycja Nowak-Sliwinska

The angiogenesis inhibitor sunitinib is a tyrosine kinase inhibitor that acts mainly on the VEGF and PDGF pathways. We have previously shown that sunitinib is sequestered in the lysosomes of exposed tumor and endothelial cells. This phenomenon is part of t ...

Study of the influence of over-the-counter vitamin supplement intake on urine fluorescence to optimize cancer detection by fluorescence cystoscopy

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Carla Martoccia

Fluorescence cystoscopy (FC) efficiently enhances the detection and improves the therapeutic management of early bladder cancer. During an FC, about 150 ml of water is needed to inflate the bladder. The water is quickly diluted by urine which can be fluore ...

A streamlined search technology for identification of synergistic drug combinations

Hubert van den Bergh, Paul Joseph Dyson, Patrycja Nowak-Sliwinska

A major key to improvement of cancer therapy is the combination of drugs. Mixing drugs that already exist on the market may offer an attractive alternative. Here we report on a new model-based streamlined feedback system control (s-FSC) method, based on a ...

Rapid optimization of drug combinations for the optimal angiostatic treatment of cancer

Hubert van den Bergh, Paul Joseph Dyson, Patrycja Nowak-Sliwinska

Drug combinations can improve angiostatic cancer treatment efficacy and enable the reduction of side effects and drug resistance. Combining drugs is non-trivial due to the high number of possibilities. We applied a feedback system control (FSC) technique w ...

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

Hubert van den Bergh, Patrycja Nowak-Sliwinska, Yiyang Li

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, ...

Optical spectroscopy of the bladder washout fluid to optimize fluorescence cystoscopy with Hexvix

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Blaise Lovisa, Carla Martoccia

Fluorescence cystoscopy enhances detection of early bladder cancer. Water used to inflate the bladder during the procedure rapidly contains urine, which may contain fluorochromes. This frequently degrades fluorescence images. Samples of bladder washout flu ...
