Abstract: By this invention, compositions and methods of use related to &bgr;-ketoacyl-ACP synthases. Of special interest are synthases obtainable from Cuphea species. Amino acid and nucleic acid for synthase protein factors are provided, as well as methods to utilize such sequences in constructs for production of genetically engineered plants having altered fatty acid compositions. Of particular interest is the expression of synthase protein factors in conjunction with expression of plant medium-chain acyl-ACP thioesterases for production of increased levels and/or modified ratios of medium-chain fatty acids in oils of transgenic plant seeds.

Abstract: A parasiticidal pellet system which delivers both immediate and long term control of parasite infestation in an animal as part of a single implant procedure. The system includes an implanter apparatus for subcutaneously implanting parasiticidal pellets in an animal through the bore of a hypodermic needle which is operably coupled to a pellet magazine, and a plurality of pellets sized to be implanted through the needle and positioned in the magazine for selective alignment of a pellet with the needle. The pellets include at least one immediate release parasiticidal agent first dose pellet and at least one extended release parasiticidal agent dose second pellet. The combined pellets are packaged in the magazine in sequential order for simultaneous delivery of an immediate dose and an extended dose as part of a single injection.

Abstract: Isolated nucleic acid molecules are disclosed, comprising an alphavirus nonstructural protein gene which, when operably incorporated into a recombinant alphavirus particle, eukaryotic layered vector initiation system, or RNA vector replicon, has a reduced level of vector-specific RNA synthesis, as compared to wild-type, and the same or greater level of proteins encoded by RNA transcribed from the viral junction region promoter, as compared to a wild-type recombinant alphavirus particle. Also disclosed are RNA vector replicons, alphavirus vector constructs, and eukaryotic layered vector initiation systems which contain the above-identified nucleic acid molecules.

Abstract: A radiation protection system around a patient on an x-ray table includes a radiation protection wall with an opening around the x-ray table, a radiation screen over the patient, and a flexible interface joining the cubicle and the x-ray table. The wall shields medical personnel in an operating region from most radiation output by an x-ray emitter. The radiation screen is attached to the x-ray table such that it can be retracted to the foot of the x-ray table and extended over the patient such that it is interposed between the patient and the medical personnel. The interface has flexible joints attached to the wall and a flexible radiation-resistant skirt that joins the wall to the screen and covers the opening in the wall. An access port may be formed in the screen, and a shielding cloak can cover the access port to surround medical instruments that are threaded through the port and inserted into the patient.
