Abstract: Methods for diagnosing, treating, and preventing catabolism-related vitamin D  deficiency and related disorders; related compositions, apparatus and kits, are disclosed. A method involves measuring CYP24 expression and/or activity, or a proxy thereof such as FGF23 level, in a patient and correlating abnormally elevated CYP24 expression and/or activity with catabolism-related vitamin D deficiency or with susceptibility for catabolism-related vitamin D  deficiency. In response to abnormally elevated CYP24 expression and/or activity, the method further includes administering a CYP24 inhibitor to the vitamin D deficient or at-risk patient, and preferably avoiding activation of the vitamin D binding receptor, such as by avoiding administration of active vitamin D compounds to such patients. Optionally, a vitamin D prohormone or prohormone can be administered.

Abstract: The present invention provides an improved method for the biological production of 1,3-propanediol from a fermentable carbon source in a single microorganism. In one aspect of the present invention, an improved process for the conversion of glucose to 1,3--propanediol is achieved by the use of an E. coli transformed with the Klebsiella pneumoniae dha regulon genes dhaR, orfY, dhaT, orfX, orfW, dhaB1, dhaB2, dhaB3, and orfZ, all these genes arranged in the same genetic organization as found in wild type Klebsiella pneumoniae.  In another aspect of the present invention, an improved process for the production of 1,3--propanediol from glucose using a recombinant E. coli containing genes encoding a G3PDH, a G3P phosphatase, a dehydratase, and a dehydratase reactivation factor compared to an identical process using a recombinant E. coli containing genes encoding a G3PDH, a G3P  phosphatase, a dehydratase, a dehydratase reactivation factor and a 1,3-propanediol oxidoreductase (dhaT). The dramatically improved process relies on the presence in E. Coli of a gene encoding a non-specific catalytic activity sufficient to convert 3--hydroxypropionaldehyde to 1,3-propanediol.

Abstract: We found mutations of the R132 residue of isocitrate dehydrogenase 1 (IDH1) in the majority of grade II and III astrocytomas and oligodendrogliomas as well as in glioblastomas that develop from these lower grade lesions. Those tumors without mutations in IDH1 often had mutations at the analogous R172 residue of the closely related IDH2 gene. These findings have important implications for the pathogenesis and diagnosis of malignant gliomas.

Title: Electrokinetic process and apparatus for consolidation of oil sands tailings
Inventor: SMITH GREGORY J
IPC: B03C11/00
Filed: 2011-04-07
Abstract: A method of compacting solids in situ in an oil sands extraction tailings pond. The method includes the steps of placing two or more electrodes into the tailings pond in a predetermined spacing and connecting the electrodes to a source of power, having a variable voltage. This creates at least one cathode and at least one anode and an electrical field therebetween. The electrical field is of a sufficient strength to induce flocculation of particles in the tailings and to simultaneously release water. Then the solids undergo further compaction with further water release to create a solid material having a minimum desired load bearing capacity. In a further embodiment an electrode used in carrying out the method is provided.

Abstract: The device is a rehabilitation device which aids the user is both sitting and standing. It consists of a frame constructed of tubular metal with wheels at the front and feet at the back The upper portion of the frame is articulated-it is able to move in an arch motion around the lower half of the frame, thus giving the device two modes: up and down. The upper portion is affixed to the lower by means of two parallel arms on either side which function as a means to keep the upper frame parallel to the ground throughout the movement. Two pneumatic pistons are affixed at either side, from the lower frame to one of the parallel arms and both pistons are controlled by means of a cable and hand lever. The user is able to rest their weight on the upper portion of the frame, holding onto handles and resting their forearms on the frame. The upper frame moves with them through sitting and standing motions, providing a guide for the movement, support, as well as dampening the downward force when sitting and providing upward force when standing. When the user is standing the device functions as a typical walker, providing support as the user walks.

Title: Haptic devices having an annular ribbon for intraocular lens
Inventor: CALLAHAN WAYNE B
IPC: A61F2/16
Filed: 2009-11-25
Abstract: The inventive is directed to a haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of the human eye. The haptic secures the lens in an appropriate position within the natural capsule so as to provide optimal visual acuity through the aphakic lens. The haptic ends are designed to position the lens neutrally anteriorly or posteriorly within the lens envelope. At the connection point of the ribbon portion to the solid end plate of the haptic, the haptic may be notched to facilitate compressing the lens into its injector for insertion into the eye through an incision in the cornea. Once compressed and passed through the cornea, the implanted lens will be secured by the haptics in the lens capsule once all possible natural lens material and epithelial cells have been removed.
