A major step in the development of photodynamic therapy (PDT) is the clinical optimization and evaluation of new photosensitizers (PS). Ideally, new compounds should be more effective and/or induce fewer side effects than the first generation PS such as he ...
An excellent knowledge of histopathological risk factors of superficial bladder transitional cell carcinoma is mandatory to establish the prognosis of the disease. Presence or absence of carcinoma in situ (CIS) in superficial bladder cancer is one of the m ...
Dried, fixed uncoated neuron granule cells and their neurites have been imaged in air by an atomic force microscope (AFM) in the repulsive regime of contact mode. Neurons have also been observed after swelling with glutamate or decapping. Modifications ind ...
In vivo spectrofluorometric analysis represents a tool to obtain information about fluorophore distribution in tissue. Based on a Peltier-cooled CCD we designed a fluorescence excitation and emission spectrograph which allows to obtain tissue spectra endos ...
MHC class II gene products in parenchymal cells, such as tubular epithelial cells in kidney, may play a role in the regulation of autoimmune reactions. Expression of MHC class II in renal tubular cells is normally very low, but it increases considerably un ...
To optimize photodynamic therapy (PDT) and photodetection of cancer with second-generation photosensitizers, knowledge of important variables such as the uptake of the dye and the dye contrast between normal and tumoral tissue after injection is necessary. ...
The synthetic peptide Gly-Arg-Gly-Asp-Tyr (GRGDY), which contains the RGD sequence of several adhesion molecules, was covalently grafted to the surface of otherwise poorly adhesive glass substrates and was used to determine the minimal number of ligand-rec ...
The loss of epithelial differentiation in carcinomas, which is accompanied by higher mobility and invasiveness of the tumour cells, is often a consequence of reduced intercellular adhesion. The primary cause of the "scattering" of cells in invasive carcino ...
Suckling Swiss mice were injected daily for 8 days with either electrophoretically pure (EP) mouse interferon (s.a. 4.7 x 10(8) units/mg protein), major impurities obtained in the course of purification, or partially purified mouse interferon (s.a. 1.3 x 1 ...
