OBJECTIVE • To evaluate human serum albumin (HSA), fluorescently labelled with fluorescein isothiocyanate (FITC), as a potential intravesical photodiagnostic method for the early detection of non-muscle-invasive bladder cancer. PATIENTS AND METHODS • By using multicellular spheroids prepared from normal human urothelial (NHU) cells and from different(More)
Obesity is a frequent complication following liver transplantation and is insufficiently responsive to dietary and life style advice. We studied the safety of orlistat treatment in obese and overweight liver transplant recipients (n = 15) on a stable tacrolimus-based immunosuppressive regimen. For safety reasons, the treatment period was restricted (6(More)
Polyvinylpyrrolidone (PVP)-hypericin is a potent photosensitizer that is used in the urological clinic to photodiagnose with high-sensitivity nonmuscle invasive bladder cancer (NMIBC). We examined the differential accumulation and therapeutic effects of PVP-hypericin using spheroids composed of a human urothelial cell carcinoma cell line (T24) and normal(More)
Hypericin has excellent photosensitizing properties and displays favorable tumouritropic characteristics, but at the same time exhibits minimal dark toxicity. As such, the compound is a promising photosensitizer in the context of clinical photodynamic therapy (PDT). The present study was undertaken to investigate whether a newly-synthesized series of(More)
OBJECTIVE To develop a diagnostic method relying on the preferential accumulation of a dye in non-muscle-invasive bladder cancer (NMIBC) that is visible in conjunction with white-light cystoscopy (WLC). MATERIALS AND METHODS We investigated in detail the permeation of Evans blue in urothelial cell carcinoma (UCC) spheroids prepared from T24, J82 and(More)
Hypericin is a bright red fluorescent compound that can be used in urological medicine as a photodiagnostic to detect non-muscle-invasive bladder cancer lesions. To this end a bladder instillation fluid is prepared in which the water-insoluble hypericin is solubilized by the presence of human serum albumin (HSA) to which the compound binds. In the present(More)
