Title: Aphid resistance in composites
Inventor: JANSEN JOHANNES PETRUS ANTONIU
IPC: A01H5/12
Filed: 1997-06-04
Abstract: The invention relates to plants of the Compositae family which are resistant to the aphid Nasonovia ribisnigri due to presence in the genome of the Nr resistance gene, wherein the genetic information responsible for the CRA phenotype is absent from the genome of the plant at least to such an extent that the CRA phenotype is not expressed. The plants are for example lettuce plants of the genus Lactuca, in particular L.sativa. L. and can be obtained by selecting a parent plant which is heterozygous for Nr resistance, manufacturing a segregating population, producing a progeny of substantially each plant of the segregating population, testing the progeny for resistance and CRA phenotype, selecting from a suitable progeny plants which are either resistant or which have no CRA phenotype, producing seed from these plants by self-pollination and culturing progeny from this seed in order to obtain a line, and testing the line for resistance and CRA phenotype and selecting lines which are uniformly resistant and which uniformly have a non-CRA phenotype.

Inventor: IVERSEN PATRICK L
IPC: A61K48/00
Filed: 1996-11-21
Abstract: The present invention relates to methods and compositions for the treatment of cancer using an oligonucleotide and an hydroxyl radical up-regulator. The oligonucleotide is characterized by its ability to down-regulate the path by which the cell repairs oxidative damage to its DNA. Thus, the oligonucleotide renders the tumor cells more susceptible to eradication upon exposure to the hydroxyl radical up-regulator administered substantially concomitantly with or subsequent to administration of the oligonucleotide. This novel treatment, preferentially inhibits the proliferation or kills malignant cells but not normal cells. Preferably, the oligonucleotide is antisense to the gene which encodes protein p53, although other antisense oligonucleotides can also be used. The invention also includes novel conjugates of the oligonucleotide and the hydroxyl up-regulator, as well as new oligonucleotides.

Abstract: A lampshade fitting includes a retaining member mounted on a shank, and having at least two resilient arms that extends downwardly to straddle away from an axis of the shank. The arms have proximate portions and distal portions. The biasing action between the proximate portions is smaller than that between the distal portions.      A restraining member has at least two engaging portions at its inner periphery for sliding engagement with the arms so as to move from a first position where the engaging portions act against the biasing action of the distal portions, to a second position where the engaging portions act against the biasing action of the proximate portions.      A lampshade has an annular upper wall and a skirt portion.      When the upper wall is brought to receive the distal portions while the restraining member is at the first position, it will push the restraining member toward the shank. When the upper wall continues to push the restraining member to the second position, the skirt portion will be biased by the distal portions.
