Abstract: A hot-runner system for use with an injection molding system, the hot-runner system including a hot-runner component, a material; and carbon nanotubes being combined with the material. The carbon nanotubes are dispersed, at least in part, in the material and the material includes a metal alloy. The carbon nanotubes are dispersed in the metal alloy, so that the metal alloy and the carbon nanotubes are combined to form a CNT-metal composite material.

Abstract: Provided herein are methods and compositions related to viral vectors. Also provided herein are methods and compositions for the efficient transfection of a host, for example through the highly efficient lentivector delivery system, and for the exquisite control of the timing and level of expression of the transferred sequence of interest by the simple administration of a modulator to the host harboring the transferred sequence of interest. Also disclosed are methods of making transgenic mice and transgenic mice made using compositions and methods relating to viral vectors.

Abstract: Methods and reagents for the capture of primary HIV are provided. A cell line expressing CCR5, CXCR4 and CD4 receptors binds and is infected by primary HIV. The cell line contains a marker gene sequence, the marker gene sequence expressed in near linear quantities over at least two orders of magnitude in response to HIV infection. Primary HIV is amplified to create a primary virus stock through insertion of an amplicon gene into the receptor expressing cell line. HIV amplification occurs rapidly and is operative with noninfectious HIV through amplification in the presence of an infectivity complement. The present invention is useful in determining host HIV titer, drug sensitivity, HIV amplification, gene sequencing and co-receptor utilization.

Abstract: The present invention provides a composition of matter, comprising: DNA encoding a viral Vpx protein fused to DNA encoding a protein. In another embodiment of the present invention, there is provided a composition of matter, comprising: DNA encoding a viral Vpr protein fused to DNA encoding a protein. The present invention further provides DNA, vectors and methods for expressing a lentiviral pol gene in trans, independent of the lentiviral gag-pol. A gene transduction element is optionally delivered to a lentiviral vector according to the present invention. Also provided are various methods of delivering a virus inhibitory molecule to a target in an animal. Further provided is a pharmaceutical composition.
