Extraction of Articulators in X-Ray Image Sequences

We describe a method for tracking tongue, lips, and throat in X-ray films showing the side-view of the vocal tract. The technique uses specialized histogram normalization techniques and a new tracking method that is robust against occlusion, noise, and spo ...

Stability of the fluorescence measurement of Foscan in the normal human oral cavity as an indicator of its content in early cancers of the esophagus and the bronchi

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

Photodynamic therapy (PDT) with Foscan (mTHPC) is used to cure early cancers of the esophagus or the tracheobronchial tree. However, fixed PDT parameters (drug dose, light dose, etc.) do not permit an accurate prediction of the tissue damage. Large interpa ...

Three-dimensional optical phantom and its application in photodynamic therapy

Hubert van den Bergh, Georges Wagnières

BACKGROUND AND OBJECTIVE: A technique to manufacture a stable, reproducible three-dimensional optical phantom is presented. This phantom reproduces the tissue's optical properties as well as the geometry and, to some extent, the mechanical properties of th ...

Early death due to defective neonatal lung liquid clearance in alpha-ENaC-deficient mice

Friedrich Beermann

The amiloride-sensitive epithelial sodium channel, ENaC, is a heteromultimeric protein made up of three homologous subunits (alpha, beta and gamma) (1,2). In vitro, assembly and expression of functional active sodium channels in the Xenopus oocyte is stric ...

Antibody-indocyanin conjugates for immunophotodetection of human squamous cell carcinoma in nude mice

Hubert van den Bergh, Georges Wagnières

The authors have recently shown that immunophotodetection of human colon carcinomas in nude mice and in patients is possible by using anti-carcinoembryonic antigen monoclonal antibodies (MAb) coupled to fluorescein. The most common clin. application of pho ...

Prolonged increase of corticosterone secretion by chronic social stress does not necessarily impair immune functions

Maria del Carmen Sandi Perez

The influence of a chronic social stress upon immunity was investigated in Wistar rats, submitted for four weeks to two different behavioral situations, balanced in a factorial design: housing with three females and membership rotation. The combination of ...

Photofrin II pharmacokinetics and optical dosing in tissue: apparatus and clinical measurements for the pharynx, esophagus, and tracheobronchial tree

Hubert van den Bergh, Georges Wagnières, André Châtelain

The timing has been optimized of photodetection (and possibly also phototherapy) of early cancer in the upper aerodigestive tract and bronchi and the relative concn. of fluorescent components of Photofrin II measured in patients as a function of the time a ...

Multiple regulatory elements for the glpA operon encoding anaerobic glycerol-3-phosphate dehydrogenase and the glpD operon encoding aerobic glycerol-3-phosphate dehydrogenase in Escherichia coli: further characterization of respiratory control.

Stewart Cole

In Escherichia coli, sn-glycerol-3-phosphate can be oxidized by two different flavo-dehydrogenases, an anaerobic enzyme encoded by the glpACB operon and an aerobic enzyme encoded by the glpD operon. These two operons belong to the glp regulon specifying th ...

Defective host defence mechanisms in a family with hypocalciuric hypercalcaemia and coexisting interstitial lung disease

Johan Auwerx

An extensive in vitro investigation of the host defence system was performed in 11 sibs of a large kindred with unexplained combination of familial hypocalciuric hypercalcaemia (FHH), interstitial lung disease and increased susceptibility to respiratory in ...
