IPC: G02B6/34
Filed: 1998-01-15
Abstract: An integrated multi-wavelength transmitter comprising an arrayed waveguide grating with feedback channels (32) between two coupling regions (34, 36). The multi-wavelength signal from a first coupling region (34) is reflected from a mirrored surface (54) back into the first coupling region and the arrayed waveguide grating, the mirrored surface thus forming one end of an optical cavity. Each single-wavelength output from second coupler (36) is split up into one part until it passes through a gain region (52) and is reflected back from the mirrored surface (54) whereas a second part passes modulator (58) and enters the first coupler. The multi-wavelength signal (42) from the second coupling region is the output (58) of the transmitter and contains the modulated carriers for all wavelengths.

Patent CA-2303483-A1 (CA)
Inventor: SUN YI
IPC: C12N1/15
Filed: 1998-12-15
Abstract: The present invention provides novel genes and polypeptides derived therefrom encoding a redox-sensitive protein that promotes cell growth, protects cells from apoptosis, scavenges oxygen radicals and can be used for the reversion of a tumor phenotype. In an attempt to identify gene(s) responsible for 1,10-phenanthroline (OP)-induced apoptosis in tumor cells we have used the differential display technique and cloned an OP-inducible gene, SAG (Sensitive to Apoptosis Gene). SAG encodes a novel, redox-sensitive, heme-binding protein with a zinc RING finger domain. The SAG protein consists of 113 amino acids with a calculated molecular weight of 12.7 kDa. Antisense SAG transfection inhibits certain tumor cell phenotypes in DLD1 human cell line and microinjection of SAG RNA stimulates cell growth. We propose that SAG protein is a cellular protective molecule functioning as a redox sensor to buffer oxidative-stress induced damage as well as a growth factor to stimulate cell growth. SAG protein will be an ideal molecular target in the development of drugs against neurodegenerative disorders, cancers, muscle dystrophy, and promoting wound healing.
