Combination therapy using aspirin-enhanced photodynamic selective drug delivery

In photodynamic therapy (PDT), excitation of a drug by light leads to a cascade of biochemical processes that can cause closure of blood vessels. It has been observed clinically that significant short-term leakage from the irradiated vasculature can occur ...

Improvement of the Contrast in Cancer Detection by Autofluorescence Bronchoscopy using a narrow spectral violet Excitation: A preliminary study

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht, Blaise Lovisa

Autofluorescence (AF) bronchoscopy is a useful tool for early cancer detection. However, the mechanisms involved in this diagnosis procedure are poorly understood. We present a clinical autofluorescence imaging study to assess the depth of the principal co ...

Hexyl-aminolevulinate-mediated photodynamic therapy: how to spare normal urothelium. An in vitro approach

Hubert van den Bergh, Pavel Kucera, Céline Ritter Schenk

Photodynamic therapy (PDT) of superficial bladder cancer may cause damages to the normal surrounding bladder wall. Prevention of these is important for bladder healing. We studied the influence of photosensitizer concentration, irradiation parameters, and ...

Optimized autofluorescence bronchoscopy using additional backscattered red light

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht

Autofluorescence bronchoscopy (AFB) has been shown to be a highly sensitive tool for the detection of early endobronchial cancers. When excited with blue-violet light, early neoplasia in the bronchi tend to show a decrease of autofluorescence in the green ...

Air quality modelling over Bogota, Colombia: Combined techniques to estimate and evaluate emission inventories

Hubert van den Bergh, Alain Clappier, Erika Maria Zarate Torres, Luis Carlos Belalcazar Ceron

Two versions of the Emission Inventory (EI) are generated for the city of Bogota, Colombia. In the first version (EI-1), CORINAIR traffic emission factors (EFs) are used. In the second (EI-2), bulk traffic EF's calculated for the city, using in situ measur ...

Effect of nanoparticle size on the extravasation and the photothrombic activity of meso(p-tetracarboxyphenyl)porphyrin

Hubert van den Bergh, Elodie Debefve

Particle size should be optimized to achieve targeted and extended drug delivery to the affected tissues. We describe here the effects of the mean particle size on the pharmacokinetics and photothrombic activity of meso-tetra(carboxyphenyl)porphyrin (TCPP) ...

The kinetics of H2O vapor condensation and evaporation on different types of ice in the range 130-210 K

Michel Rossi, Hubert van den Bergh, Pascal Pratte

The kinetics of condensation (kc) and the evaporation flux (J(ev)) of H2O on ice were studied in the range 130-210 K using pulsed-valve and steady-state techniques in a low-pressure flow reactor. The uptake coefficient gamma was measured for different type ...
