Title: Isolation and characterization of plant regulatory sequences
Inventor: BARTHELS NATHALIE
IPC: A01H5/00
Filed: 1998-11-26
Abstract: In the search for plant regulatory sequences capable of driving nematode-triggered effector gene expression in feeding structures the promoter tagging appears to be a valuable tool. A large collection of transgenic Arabidopsis thaliana(L.) plants was generated. They were transformed with a .beta.-glucuronidase gene functioning as a promoter tag. Two T-DNA constructs, pGV1047 and p.DELTA.gusBin19 were used. Early responses to nematode invasion were of primary interest. Four lines exhibiting GUS activity in syncytia induced by the beet cyst nematode were studied. Reporter gene activation was also identified in galls induced by root knot and ectoparasitic nematodes.  Time course studies revealed that the four tags were differentially activated during the development of the feeding structure. T-DNA-flanking regions responsible for the observed responses after nematode infection were isolated and characterized for promoter activity.
Patent CA-2313818-A1 (CA)
Title: Demodulation method for receiver
Inventor: RUPP MARKUS
IPC: H04B7/24
Filed: 2000-07-12
Abstract: In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known à priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

The location information is extracted (250) from the received communication packet and cached (260). When an incoming data packet is received (300) by the gateway packet switch node (150), a determination is made (310) as to whether the location information for the destination mobile station (110) is stored within the cache (165). If the location information is stored within the cache (165) the location information is retrieved (340) from the cache (165) and the data packet is routed (350) to the mobile station (110). Otherwise, the location information is retrieved (320) from a home location register (197) and the data packet is routed (330) to the mobile station (110).

Title: Novel dna-based vaccine against the encephalitis alphaviruses
Inventor: NAGATA LESLIE P
IPC: C12N7/00
Filed: 2000-12-21
Abstract: This invention relates to the development of a mammalian expression vector, under which expression of the structural genes of western equine encephalitis virus have been placed under the control of an eucaryotic promoter. When the recombinant vector is administered to mammalian cell culture or using a cell-free transcription/translation system, in vitro, authentic structural proteins of western equine encephalitis virus are produced as verified by reactivity with monoclonal antibodies developed to western equine encephalitis virus. When the recombinant DNA molecule is administered in vivo, a protective immune response is induced, thereby enhancing protection of the individual against subsequent infection by western equine encephalitis virus. In a similar manner, DNA vaccines to related alphaviruses (Venezuelan and eastern equine encephalitis viruses) could also be developed.

Title: Di-behenyl fumarate and its use in dermatological products
Inventor: FOGEL ARNOLD W
IPC: A61Q19/00
Filed: 1999-03-25
Abstract: The present invention relates to novel anhydrous or water-in-oil synthetic ester compositions which are used in formulating dermatological products having uniform structure ranging in consistency from a soft gel to a hard stick. The compositions comprise a new component, di-behenyl fumaric acid ester, which has a melting point of approximately 72-74 °C. The di-behenyl fumaric acid ester component has exceptional benefits when used in combination with any cosmetically acceptable oil in varying ratios, to produce homogeneous materials having a uniform structure. The di-behenyl fumaric acid ester according to the present invention may be used to harden or stiffen any cosmetically acceptable oil or water-in-oil emulsions and can be used to create compositions varying widely in viscosity and/or hardness from gels to solid systems such as sticks or to enhance the stability of water-in-oil emulsions. The compositions according to the present invention are particularly useful as additives in dermatological products, including cosmetic compositions and can accomodate components which vary widely in hydrophobicity of hydrophilicity.
Patent CA-2328471-A1 (CA)
Title: Polyhydroxyalkanoate biopolymer compositions
Inventor: SKRALY FRANK A
IPC: C12N1/21
Filed: 1999-05-21
Abstract: Several novel PHA polymer compositions produced using biological sytems include monomers such as 3-hydroxybutyrate, 3-hydroxypropionate, 2-hydroxybutyrate, 3-hydroxyvalerate, 4-hydroxybutyrate, 4-hydroxyvalerate and 5-hydroxyvalerate. These PHA compositions can readily be extended to incorporate additional monomers including, for example, 3-hydroxyhexanoate, 4-hydroxyhexanoate, 6-hydroxyhexanoate or other longer chain 3-hydroxyacids containing seven or more carbons. This can be accomplished by taking natural PHA producers and mutating through chemical or transposon mutagenesis to delete or inactivate genes encoding undesirable activities. Alternatively, the strains can be genetically engineered to express only those enzymes required for the production of the desired polymer composition. Methods for genetically engineering PHA producing microbes are widely known in the art (Huisman and Madison, 1998, Microbiology and Molecular Biology Reviews, <u>63</u>: 21-53).  These polymers have a variety of uses in medical, industrial and other commercial areas.

Abstract: An externally threaded nipple (24) fits through a circular opening (38) in a flexible wall (14). The nipple (24) is a part of a first ring member (18) that includes a radial portion with a radial surface (30) that contacts the flexible wall where it surrounds the opening (38). An internally threaded second ring (20) is brought to the opening (38) from the opposite side of the wall (14). Its internal threads (34) are screwed onto the external threads (26) on the nipple (24). The screwing of the second ring member (20) onto the nipple (24) moves an inner radial surface on the ring member (20) into engagement with the flexible wall (14) directly opposite its contact with inner wall (30). The first and second ring member (18, 20) become connected together and the portion of the flexible wall (14) that immediately surrounds the opening (38) in the flexible wall (14) is trapped by and between the two inner side surfaces (30, 36) of the two ring members (18, 20).
