Photodynamic therapy (PDT) is a new treatment for head and neck cancer. The principle of the treatment is a photochemical reaction initiated by light activation of a photosensitizer, which causes the death of the exposed tissue. This article presents the modes of action of PDT and the techniques as well as the clinical procedure. A critical review of the(More)
A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at √ s = 189–209 GeV, corresponding to an integrated luminosity of approximately 600 pb −1. Charged Higgs bosons are assumed to be pair-produced and to decay into q¯ q, τ ν τ(More)
