Abstract: The disclosure provides a plasmid and a lentiviral vector system which may be used to generate lentiviral vector particles for use in transduction. The disclosed vector system and/or plasmid improves the transduction efficiency of the generated lentiviral vector particles and may be exploited to provide compositions for raising immune responses in animals and as vaccines.

Abstract: An electrical conduit ground device is provided for electrically and environmentally shielding an electric cable. The device includes a conduit having a receiving end through which the cable passes axially; an internal seal that inserts into the receiving end; a gland boss that inserts into the receiving end; an external seal that inserts into the boss and extends axially outward from the receiving end; and a grounding assembly disposed between the internal and external seals. The assembly includes an adapter for providing electrical grounding contact between the cable and the swage tube; a space-retainer for structurally supporting the adapter; and a washer for axially separating the internal and external seals. The adapter is provided for electrically connecting an interior surface of a conduit and an external surface of a cable.
