  • Publication number: 20050048818
    Abstract: An electrical connector includes a dielectric housing defining a mating space with a pair of two opposite side wall by two sides thereof, a plurality of passageways formed in an inner face of each of the side walls, a number of signal and grounding terminals received in corresponding passageways, respectively, a shielding member attached to the side walls and a grounding member. Each grounding member includes an intermediate portion and three spaced beams extending from a side of the intermediate portion along a same direction. A middle one of the three beams is snugly retained in corresponding channel. The other two beams electrically and mechanically press the grounding terminal and the shield plate against the side wall, respectively.

  • Publication number: 20050042926
    Abstract: An electrical connector (1) includes an elongate insulative housing (10), a number of contacts (20), and a shell (30). The insulative housing has a bottom wall (11) and two side walls (12) extending upwardly from the bottom wall. The contacts include signal contacts (21) and grounding contacts (22). Each contact has an engaging portion received in the insulative housing and a soldering portion extending outwardly and horizontally from the bottom wall. The shell is assembled to exterior surfaces of the side walls and comprises a plurality of grounding fingers (31) and a pair of cut portions (33). A distant is existed between a bottom surface of the bottom wall and each cut portion.

  • Publication number: 20040220123
    Abstract: The present invention relates to the discovery, identification and characterization of toxic agents which are lethal to pathogens and methods for targeting such toxic agents to a pathogen or pathogen infected cells in order to treat and/or eradicate the infection. In particular, the present invention relates to toxic agents which target bacteria at different stages of the bacterial life cycle, which are delivered alone or in combination to bacteria or bacteria-infected cells. The invention relates to toxic agents which are lethal to diseased cells and methods for targeting such toxic agent to a diseased cell in order to treat and/or eradicate the disease. The present invention relates to promoter elements which are pathogen-specific or tissue-specific and the use of such promoter elements to achieve pathogen-specific or tissue-specific expression of the toxic agent(s) and/or ribozyme(s) of the present invention.

  • Publication number: 20040209263
    Abstract: The invention provides improved library selection procedures for nucleic acids which allow the rapid determination of accessible target sites throughout relatively long target RNAs. This invention provides an improved method of screening a library of nucleic acids to identify cleavage sites of a target RNA. The steps of the screening comprise generating the library of nucleic acids, wherein each nucleic acid comprises a catalytic core flanked by random nucleotides; adding said target RNA to the library of nucleic acids; and isolating nucleic acids that cleave said target RNA. The nucleic acids selected by the methods described herein are also provided in the invention.

  • Publication number: 20030092651
    Abstract: The present invention relates to multi-ribozymes and their use to target RNA in a tissue-specific, target RNA-specific, or pathogen-specific manner for the treatment of cancers, proliferative disease, and bacterial, parasitic and viral infections. More specifically, the present invention relates to the use of virions and viral vectors to package and deliver DNA encoding the multi-ribozymes to a host. The present invention relates to the use of liposomes and lipid-DNA complexes to deliver DNA encoding ribozymes to a host. Most specifically, the invention relates to the use of target specific virions to package and deliver DNA comprising a target specific promoter and encoding a ribozyme(s) directed to the target organism nucleic acids. The present invention further relates to a novel vectors encoding a multi-ribozyme structure with enhanced 5′ and/or 3′ autocatalytically cleaving ribozymes.
