Antitumor Effect of a Novel Photodynamic Therapy With Acetylated Glucose-conjugated Chlorin for Gastrointestinal Cancers.

Background/aim: We previously synthesized a glucose-conjugated chlorin compound e6 (G-chlorin e6), and reported that it has very strong antitumor effects. The aim of the present study was to synthesize acetylated glucose-conjugated chlorin (AcN003HP) and evaluate its antitumor effect and excretion.

Materials And Methods: To evaluate the antitumor effect of AcN003HP, its IC was calculated as well as its accumulation in cancer cells was examined by flow cytometry.

Multiple optical code-label processing using multi-wavelength frequency comb generator and multi-port optical spectrum synthesizer.

In optical packet switching (OPS) and optical code division multiple access (OCDMA) systems, label generation and processing are key technologies. Recently, several label processors have been proposed and demonstrated. However, in order to recognize N different labels, N separate devices are required.
