Time-Resolved Autofluorescence Spectroscopy of the Bronchial Mucosa for the Detection of Early Cancer: Ex vivo and Clinical Results

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht, Pascal Uehlinger

Time-resolved measurements of endogenous tissue autofluorescence were carried out on the bronchial mucosa of 18 patients during endoscopy by the means of a optical fibre-based spectrometer. The objective was to assess the fluorescence lifetime as a new con ...

Transgenic mouse models for tumors of melanocytes and retinal pigment epithelium

Friedrich Beermann

Cutaneous and ocular melanomas are due to malignant transformation of neural crest-derived melanocytes. The rising incidence of this tumor in humans has stimulated experiments to devise suitable mouse models. In the past years, transgenic mouse lines have ...

Mid-infrared spectroscopic monitoring of animal cell culture bioreactor processes

Urs von Stockar, Ian William Marison, Martin Rhiel

Mid-IR (MIR) spectroscopy in combination with partial least-squares (PLS) regression anal. was used to monitor the concns. of glucose, lactate, ammonia, and asparagine in situ during bioreactor cultivation of CHO/SSF3 cells. Simple PLS calibration models w ...

Long circulating half-life and high tumor selectivity of the photosensitizer meta-tetrahydroxyphenylchlorin conjugated to polyethylene glycol in nude mice grafted with a human colon carcinoma

Hubert van den Bergh, Georges Wagnières

In a model of nude mice bearing a human colon carcinoma xenograft, the biodistribution and tumor localization of metatetrahydroxyphenylchlorin (m-THPC) coupled to polyethylene glycol (PEG) were compared with those of the free form of this photosensitizer u ...

High-resolution holography and biopsy: Preliminary results

Christian Depeursinge

For holographic biopsy purposes, holograms of biological tissue samples have been recorded in vitro to establish the possibility of differentiating tissues on the holograms. With the use of specific absorbing dyes for staining tissues, the contrast has bee ...

Human papillomavirus type 42: new sequences, conserved genome organization.

Stewart Cole

We report the nucleotide sequence and genome organization of the human papillomavirus type 42. HPV42 DNA was isolated from vulvar papillomas. It has been detected in benign forms of proliferative lesions only. The genome of HPV42 is 7917 bp long and shows ...

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 ...

Antibody-fluorescein conjugates for photoimmunodiagnosis of human colon carcinoma in nude mice

Hubert van den Bergh, Georges Wagnières

To improve the detectability of tumors by light-induced fluorescence, the use of monoclonal antibodies (MoAb) as carriers of fluorescent molecules was studied. As a model for this approach, the biodistribution of an anticarcinoembryonic antigen (CEA) MoAb ...
