Abstract: The present invention relates to supplementing the diets to sows during the periods of gestation, lactation, and breeding by feeding L-carnitine and chromium. The supplementation enhances pork productivity by increasing the number of pigs born alive in the subsequent reproductive cycle. Sow diets of this invention include L-carnitine and L-carnitine salts and trivalent chromium salts, such as chromium picolinate and chromium nicotinate. L-Carnitine is generally added to the swine feed formulation in the amount of from about 20 to about 1500 ppm, and the trivalent chromium salt is generally added to the swine feed formulation in the amount of from about 20 ppb to about 1000 ppb. The invention also relates to supplemented sow diets and feed supplement formulation.

Abstract: The present invention relates to isolated nucleic acid molecules encoding a type III—secreted bacterial protein capable of modifying a cell death pathway in a plant cell. One aspect of the present invention involves an isolated nucleic acid molecule having a nucleotide sequence that encodes the HopPtoD2 protein of Pseudomonas syringae pv. syringae DC 3000. Expression vectors, host cells, and transgenic plants which include the DNA molecules of the present invention are also disclosed. The nucleic acid molecules of the present invention can be used to impart disease resistance to a plant and to make a plant hypersusceptible to colonization by nonpathogenic bacteria.

Abstract: The present invention describes a technique for achieving high peak power output in a laser employing single-stage, multi-pass amplification. High gain is achieved by employing a very small “seed” beam diameter in gain medium, and maintaining the small beam diameter for multiple high-gain pre-amplification passes through a pumped gain medium, then leading the beam out of the amplifier cavity, changing the beam diameter and sending it back to the amplifier cavity for additional, high-power amplification passes through the gain medium. In these power amplification passes, the beam diameter in gain medium is increased and carefully matched to the pump laser's beam diameter for high efficiency extraction of energy from the pumped gain medium. A method of “grooming” the beam by means of a far-field spatial filter in the process of changing the beam size within the single-stage amplifier is also described.

The potency of these compounds is in a similar magnitude as daunomycin, a currently used anticancer drug. Each compound of the invention produces one or more desired effects (blocking nucleoside transport, inhibiting nucleic acid or protein syntheses, decreasing the proliferation and viability of cancer cells, inducing DNA fragmentation or retaining their effectiveness against multidrug-resistant tumor cells).

Abstract: Stem cells from human sources can have a variety of useful applications in disease treatment and biotechnology. More particularly the umbilical cord matrix cell cultures of the invention have a variety of totipotent, pluripotent, or multipotent cells for a variety of end uses from a non-controversial, universally available, species-specific source. The technology can have application to any amniotic animal, including agricultural and laboratory animals and humans. The invention relates to isolating the stem cells, culturing the stem cells, maintaining the stem cells, transforming the stem cells into useful cell types using genetic or other transformation technologies, stem cell and tissue banking and using untransformed or transformed cells in disease treatment.

Abstract: Methods of growing plants having modified transpiration rates are provided. Such methods permit more efficient water conservation through regulation of stomatal closure responses. Accordingly, modified plants can be grown in areas which were previously unsuitable for growth and plants which can withstand drought conditions can be grown.

Abstract: The present invention provides a family of peptides based upon the M2GlyR sequence. These peptides are derivatives of the M2GlyR sequence and can be modified at their ends to include a plurality of polar amino acid residues to enhance their solubility. Particularly preferred derivatives include portions of the M2GlyR sequence which are palindromic to another portion of the peptide or to the M2GlyR sequence itself. Preferably these portions are at least 7 amino acid residues in length. Peptides embraced by the present invention are characterized by having greater effects on the transepithelial electrical resistance of cells at lower concentrations. Peptides of the present invention have been shown to increase Isc in MDCK epithelial cell monolayers with half maximal effects observed at or below 30 &mgr;M, a nearly 10-fold improvement over any peptide previously characterized in the M2GlyR family.

Abstract: Porcine reproductive and respiratory syndrome virus (PRRSV) causes serious economic losses in swine. The present invention determined that CD 151 is a susceptibility factor for PRRSV infection by transfecting a cell line which is not susceptible to PRRSV infection (BHK-21) with CD 151, which rendered the cell line susceptible. Because CD 151 can be accessed in cellular material including blood platelets and germplasm, the present invention provides a non-invasive method of screening different swine for susceptibility to PRRSV, thereby improving breeding plans. In the case of a valuable animal, results from such screening can indicate any offspring's susceptibility to PPRSV. Additionally, the viral RNA-CD 151 interaction possesses high affinity and can be used as a tool to detect anti-viral compounds which can be further improved by using combinatorial chemistry. Accordingly, anti-viral compounds that can block the viral RNA-CD 151 interaction can be developed.

Abstract: Molding apparatus (10) is provided which allows use of a particulate non-liquid molding material (121) to produce a variety of articles, such as frustoconical barrel segments (122). The apparatus (10) includes a female mold segment (18) including generally annular inner and outer sidewalls (70, 76) and a complemental male mold section (20) having an annular sidewall unit (30). In use, a molding material (121) is placed between the sidewalls (70, 76) and the section (20) is shifted so that it telescopes within the section (18); this compresses the material (121) to a desired final shape, which is then hardened to yield the final product (122). An optional wear insert (26) can be used with female mold section (18), which can be replaced as needed and assists in cleaning of the apparatus (10).

Abstract: New polyoxometalate compounds and polymers comprising recurring monomers of those compounds are provided. The compounds are formed by replacing at least one oxide of the starting polyoxometalate with an organoimido (NR) group bonded to the polyoxometalate via a triple bond to the nitrogen atom. The R of the (NR) group comprises a reactive functional group which renders the compound readily polymerizable, alone or with other monomers (e.g., divinylbenzene), to form the inventive polymers. Additionally, a countercation (e.g., bis(tetra-n-butylammonium)) can be mixed with the polyoxometalate compounds in order to neutralize the negative charge thereof as well as to make those compounds more soluble in organic solvents.
