Publication number: 20110272282Abstract: Methods and apparatus for concentrating particles may be applied, for example, to concentrating DNA, RNA, proteins and the like. Proteins may be pre-treated to facilitate concentration by scodaphoresis. The pre-treatment may comprise, for example, heating or chemical treatment to denature and/or apply a net charge to the protein, binding handle particles to the protein and combinations thereof. High-conductivity samples may be subjected to a conductivity-reduction step to facilitate electrical injection of target particles into scodaphoresis media. The conductivity-reduction step may comprise a buffer exchange process or a salt extraction process, for example. Methods and apparatus can allow two or more different types of target particles to be extracted from the same sample and separately concentrated. These various aspects may be applied individually or in any combination.Type: ApplicationFiled: November 10, 2009Publication date: November 10, 2011Applicant: University of British ColumbiaInventors: Andrea Marziali, David John Broemeling, Joel Pel, Jason Donald Thompson, Jaryn Perkins, Thomas Willis, Herbert Heyneker, Darren Gray, Carolina Tropini

Patent number: 8040591Abstract: A reflective display having a plurality of transparent hemi-beads (60), each having a reflective region (80) surrounding a non-reflective region (82). Light absorbing, electrostatically charged ions are dissolved in an electrophoretic medium (20) maintained adjacent the hemi-beads. A voltage applied across the medium moves many ions into an evanescent wave region adjacent the hemi-beads where the ions absorb light, frustrating TIR at the reflective regions. Ions in the evanescent wave region also absorb light which does not undergo TIR and which would otherwise pass through the non-reflective regions. An opposite voltage applied across the medium moves many ions away from the hemi-beads, allowing light to undergo TIR at the reflective regions. The display's brightness can be enhanced by providing a backplane electrode (48) having reflective regions (108; 110, 112) for reflecting back through the hemi-beads light which passes through the non-reflective regions to the backplane electrode.Type: GrantFiled: April 10, 2007Date of Patent: October 18, 2011Assignee: The University of British ColumbiaInventor: Lorne A. Whitehead

Patent number: 8021686Abstract: Methods for the preparation of a lipid-nucleic acid composition are provided. According to the methods, a mixture of lipids containing a protonatable or deprotonatable lipid, for example an amino lipid and a lipid such as a PEG- or Polyamide oligomer-modified lipid is combined with a buffered aqueous solution of a charged therapeutic agent, for example polyanionic nucleic acids, to produce particles in which the therapeutic agent is encapsulated in a lipid vesicle. Surface charges on the lipid particles are at least partially neutralized to provide surface-neutralized lipid-encapsulated compositions of the therapeutic agents. The method permits the preparation of compositions with high ratios of therapeutic agent to lipid and with encapsulation efficiencies in excess of 50%.Type: GrantFiled: February 8, 2008Date of Patent: September 20, 2011Assignee: The University of British ColumbiaInventors: Sean C.

Patent number: 8000014Abstract: Longitudinally adjacent plane mirrors (106-114) are pivotally interconnected in a columnar array (56) by non-stretching linkages (120) which constrain movement of the mirrors such that their normal vectors (115) remain parallel. Pivotable couplings (122, 124) in two mirrors permit movement of the mirrors with respect to mutually perpendicular axes (x, y) and prevent movement of the mirrors with respect to a third axis (z). Two actuators (117A, 117B) coupled to one of the pivotable couplings controllably move a selected mirror with respect to the mutually perpendicular axes (x, y). A first frame (116) couples the mirror columns together so that movement of the selected mirror moves all the mirrors in unison. The actuators controllably move the mirrors to orient the normal vectors such that the mirrors specularly reflect incident light in a preselected direction.Type: GrantFiled: June 16, 2008Date of Patent: August 16, 2011Assignee: The University of British ColumbiaInventors: Lorne A. Whitehead, Jon David Edward Scott

Patent number: 7973017Abstract: Agents that reduce the amount of IGFBP-2 and/or IGFBP-5 and that are known to be useful in the treatment of cancer result in increased expression of the protein clusterin. Since clusterin can provide protection against apoptosis, this secondary effect detracts from the efficacy of the therapeutic agent. In overcoming this, the present invention provides a combination of therapeutic agents that is useful in the treatment of cancer. The combination includes an agent that reduces the amount of IGFBP-2 and/or IGFBP-5 and that stimulates expression of clusterin as a secondary effect, and an oligonucleotide that is effective to reduce the amount of clusterin in cancer cells. In some embodiments of the invention, the agent that reduces IGFBP-2 and/or IGFBP-5 is a bispecific antisense species. The oligonucleotide may be an antisense oligonucleotide or an RNAi oligonucleotide.Type: GrantFiled: November 23, 2005Date of Patent: July 5, 2011Assignee: The University of British ColumbiaInventor: Martin Gleave

These sequences target clusterin, IGFBP-5, IGFBP-2, both IGFBP-2 and -5 simultaneously, Mitf, and B-raf. The invention further provides for the use of these RNAi sequences in the treatment of cancers of various types, including prostate cancer, sarcomas such as osteosarcoma, renal cell carcinoma, breast cancer, bladder cancer, lung cancer, colon cancer, ovarian cancer, anaplastic large cell lymphoma and melanoma; and Alzheimer's disease, and a method of treating such conditions through the administration of the RNA molecules with RNAi activity to an individual, including a human individual in need of such treatment.Type: GrantFiled: February 23, 2006Date of Patent: June 21, 2011Assignee: The University of British ColumbiaInventors: Martin E.

Patent number: 7955865Abstract: Apparatus for dispensing droplets of reagent onto samples includes a probe tip to which droplets of reagent can adhere. The apparatus advances the probe tip toward a sample until a droplet of reagent touches the sample and is pulled off from the probe tip. A sensor detects that the droplet has been pulled off from the probe tip and halts the advance of the probe tip before the probe tip touches the sample. Such apparatus may be used to automatically dispense small volumes of reagent onto fragile samples.Type: GrantFiled: June 9, 2005Date of Patent: June 7, 2011Assignee: The University of British ColumbiaInventors: Andrea Marziali, Diponkar Banerjee, Jason Donald Thompson, Kurtis Dan Guggenheimer, Jared Raymond Slobodan, Roy Alexander Belak, David Keddie Brown

Publication number: 20110100215Abstract: Described herein are a method and a reactor for reducing NOx contained in a gaseous emission stream. The method and the reactor both utilize an adsorption region in which NOx is adsorbed by either a catalyst material or a non-catalytic adsorbent material and a reduction region in which the adsorbed NOx is catalytically reduced by a hydrocarbon stream. Concentrations of components that inhibit catalytic NOx reduction, such as water vapour, oxygen, and sulphur dioxide, are lower in the reduction region than in the adsorption region. By adsorbing NOx in the adsorption region of the reactor and reducing NOx in the reduction region of the reactor, the reactor and method described herein allow for the efficient reduction of NOx from the emission stream even when the emission stream has a relatively high concentration of components that can inhibit efficient NOx reduction.Type: ApplicationFiled: March 31, 2009Publication date: May 5, 2011Applicant: The University of British ColumbiaInventors: Xiaotao Bi, Tianxue Yang
