  • Patent number: 6506917
    Abstract: In accordance with the present invention, there are provided methods to modulate processes mediated by retinoid receptors, employing high affinity, high specificity ligands for such receptors. In one aspect of the present invention, there are provided ligands which are more selective for the retinoid X receptor than is retinoic acid (i.e., rexoids). In another aspect of the present invention, alternative ligands (other than retinoic acid) have been discovered which are capable of inducing retinoic acid receptor mediated processes. In yet another aspect, methods have been developed for the preparation of such retinoid receptor ligands from readily available compounds.

  • Patent number: 6506935
    Abstract: For the removal of trace quantities of iodine-containing contaminants from corrosive liquid feed streams (e.g. commercial acetic acid), an adsorbent with distinct advantages over prior-art materials is provided. The overall treatment method involves the use of a suitable zeolite having a silica to alumina molar ratio from about 5 to less than 15 that has been cation-exchanged with an iodine-reactive metal. This inorganic adsorbent may be used in unbound form, or it can be bound with a substantially insoluble porous inorganic refractory metal oxide binder. Reactivation and regeneration techniques, which are generally incompatible with prior-art adsorbent materials, are also disclosed. In general, it is advantageous to pretreat the feed streams to remove the most easily separable contaminants (e.g. iodine, hydrogen iodide, and metal cations) and thereby reduce the iodine compound loading and detrimental effects of metals on the adsorbent. Thus, the expensive iodine reactive metal (e.g.

  • Patent number: 6506955
    Abstract: A boiling water reactor is chemically decontaminated by circulating a decontamination solution through reactor recirculation loops and the annulus region of a reactor pressure vessel that surrounds the central core region while bypassing the central core region. The decontamination solution may also be circulated between the annulus region and a lower internals region while bypassing the central core region. The solution dissolves or breaks down metal oxide layers on the surfaces of the boiling water reactor. The metal oxide layers in the central core region and the activated metal ions contained in these layers, which do not substantially contribute to personnel exposure, are not released and, therefore, do not need to be removed from the solution.

  • Patent number: 6506958
    Abstract: There is provided a tampon that comprises an absorbent pledget and a menstrual fluid indicator associated therewith. The absorbent pledget has a proximal end that is placed near the cervical bone and a distal end opposite the proximal end. The indicator is preferably an additional layer formed and in contact with the entire circumference of the absorbent pledget, and is located near the distal end. The indicator is designed to provide a sensory signal to the user that the capacity of the absorbent pledget of the tampon is exhausted, or just before by-pass leakage commences.

  • Patent number: 6506961
    Abstract: A disposable absorbent article, e.g., a pantiliner, or other absorbent pad. The pad is an elongated generally planar member having a general hour-glass shape periphery including a pair of concave, side sections interconnecting respective ones of a pair of convex end sections. The pad basically comprises a top-sheet, a fluid absorbent core, and a cover sheet. The top sheet is formed of a fluid pervious material, e.g., a non-woven material, and is disposed over the absorbent core. The absorbent core comprises a fluid absorbing material, e.g., cellulosic fluff and super-absorbent particles, and is disposed over the cover sheet. The cover sheet is formed of a fluid impervious material, e.g., a plastic film. The top-sheet, the fluid absorbent core and the cover sheet are bonded, e.g., thermally bonded, together along plural concentric lines located adjacent the periphery of the pad. The plural concentric lines form a barrier resistant to the egress of fluid out of the periphery of the pad.

  • Patent number: 6506963
    Abstract: This invention relates to transgenic winter oilseed rape (WOSR) plants, plant material and seeds, characterized by harboring a specific transformation event. It pertains to winter oilseed rape plants, more particularly to a pair of winter oilseed rape plants, which is particularly suited for the production of hybrid seed. More specifically, one plant is characterized by being male-sterile, due to the presence in its genome of a male sterility gene. The invention further provides a method for producing hybrid seed, a process for producing a transgenic WOSR plant oil or plant, and a method to identify a transgenic plant, cell or tissue. A kit for identifying the transgenic plants comparing the elite event of the present invention is also described. The WOSR plants of the invention combine the ability to form hybrid seeds with optimal agronomic performance, generic stability and adaptability to different generic backgrounds.
