Chromosomal Number Aberrations and Transformation in Adult Mouse Retinal Stem Cells In Vitro

Purpose. The potential of stem cells (SCs) as a source for cell-based therapy on a wide range of degenerative diseases and damaged tissues such as retinal degeneration has been recognized. Generation of a high number of retinal stem cells (RSCs) in vitro w ...

Organometallic complexes that interconvert between trimeric and monomeric structures as a function of pH and their effect on human cancer and fibroblast cells

Paul Joseph Dyson, Rosario Scopelliti, Kay Severin, Wee Han Ang, Zacharias Immanuel Grote

Organometallic half-sandwich complexes based on ruthenium with aminomethyl-substituted 3-hydroxy-2-pyridone ligands exist in aqueous solution as monomeric O,O′-chelate complexes or trimeric metallamacrocycles depending upon the pH. We hypothesized that adm ...

Routine experimental system for defining conditions used in photodynamic therapy and fluorescence photodetection of (non-) neoplastic epithelia

Hubert van den Bergh, Pavel Kucera

A common method to induce enhanced short-term endogenous porphyrin synthesis and accumulation in cell is the topical, systemic application of 5-aminolevulinic acid or one of its derivatives. This circumvents the intravenous administration of photosensitize ...

Iontophoretic delivery of 5-aminolevulinic acid (ALA) and a series of ALA esters into and through the skin

Hubert van den Bergh

Iontophoretic delivery of a homologous series of cationic ALA esters, into and through the skin, has been detd. and compared to that of the zwitterionic parent drug. The roles of electrorepulsion and electroosmosis have been deduced. ...

Photodynamic therapy for 101 early cancers of the upper aerodigestive tract, the esophagus, and the bronchi: a single-institution experience

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

Cancer, when detected at an early stage, has a very good probability of being eradicated by surgery or radiotherapy. However, less aggressive treatments also tend to provide high rates of cure without the side effects of radical therapy. We report on the r ...
