This process comprises adding to the blood or blood component containing pathogens an effective amount of riboflavin, and exposing the fluid to light of an appropriate wavelength to damage the nucleic acid of the pathogen and to substantially maintain the damage to the pathogenic nucleic acids to allow for subsequent transfusion into a recipient.Type: GrantFiled: August 25, 2003Date of Patent: March 8, 2011Assignee: CaridianBCT Biotechnologies, LLCInventors: Robert Owen Lockerbie, Vijay Kumar, Shawn D. Keil, Raymond P. Goodrich

Publication number: 20100317054Abstract: The present invention relates to the cloning, identification and characterization of the unique and entire genomic sequences encoding new porcine DC-SIGN and LSECtin proteins, including the novel nucleotide sequences of the full-length cDNA and genes of both pDC-SIGN gene and pLSECtin. Also provided are the nucleic acid molecules encoding newly discovered porcine ICAM-3 isoforms from porcine monocyte-derived dendritic cells and the use thereof. Specifically, the invention is drawn to an isolated nucleic acid molecule comprising a nucleotide sequence encoding one or more of porcine DC-SIGN, porcine ICAM-3, porcine LSECtin, a complement of the nucleotide sequence or a functional, defined portion of the nucleotide sequence or a protein fusion product linked to a protein that may be of porcine or human origin.Type: ApplicationFiled: October 29, 2008Publication date: December 16, 2010Applicant: VIRGINIA TECH INTELLECTUAL PROPERTIES, INC.Inventors: Yaowei Huang, Xiang-Jin Meng

Publication number: 20100278789Abstract: A method of increasing insulin content in adult islet beta cells is disclosed. The method comprises contacting the adult islet beta cells with an agent capable of down-regulating activity and/or expression of at least one component participating in a NOTCH pathway, the component being up-regulated in beta cell dedifferentiation above a predetermined threshold, thereby increasing the insulin content in adult islet beta cells. Methods of labeling dedifferentiated adult islet beta cells are also disclosed. Cell populations generated using the methods of the present invention and uses thereof are also disclosed.Type: ApplicationFiled: June 17, 2010Publication date: November 4, 2010Applicant: Ramot At Tel Aviv University Ltd.Inventors: Shimon Efrat, Yael Bar
