BACKGROUND/PURPOSE Topical photodynamic therapy (PDT) is potentially useful for the treatment of non-melanoma skin cancer and other skin diseases. We investigated the therapeutic effects of PDT using topical application of aluminum phthalocyanine chloride (AlClPc) and a diode laser emitting at 670 nm in murine non-melanoma skin carcinomas. METHODS AlClPc(More)
Meso-tetra(hydroxyphenyl)chlorin (mTHPC) (INN: Temoporfin) is a potent photodynamically active substance in clinical use today. Usually, the substance is given systemically and a known drawback with this administration route is a prolonged skin light sensitization. For the first time to our knowledge, a liposomal Temoporfin gel formulation for topical(More)
Meso-tetra(hydroxyphenyl)chlorin (mTHPC) (INN: Temoporfin) is one of the most potent photodynamically active substances in clinical use. Treatment protocols for Temoporfin-mediated photodynamic therapy often rely on drug-light intervals of several days in order for the photosensitizer to accumulate within the target tissue, though tumor selectivity is(More)
Although the benefits of topical sensitizer administration have been confirmed for photodynamic therapy (PDT), ALA-induced protoporphyrin IX is the only sensitizer clinically used with this administration route. Unfortunately, ALA-PDT results in poor treatment response for thicker lesions. Here, selectivity and depth distribution of the highly potent(More)
We report on a high-performance diode-laser spectrometer operating near 657 nm with narrow linewidth (<0.6 kHz) , enhanced power (as much as 40 mW), and low drift (<10 Hz/s) . The spectrometer comprised an extended-cavity diode-laser frequency stabilized to a high-finesse optical resonator and a broad-area antireflection coated laser diode as an amplifier(More)
