  • Publication number: 20160008378
    Abstract: The present invention provides a method for inducing apoptosis in selected cells by aggravating ER-stress. The aggravation of ER-stress is achieved in a specific manner by inhibiting SERCA (sarcoplasmic/endoplasmic reticulum calcium ATPase), leading to elevated level of cytoplasmic calcium concentration, yet without inhibiting the activity of COX-2 (cyclooxygenase-2) or triggering the release of histamine. Induction of apoptosis may be enhanced by first inducing or further aggravating ER-stress through inhibition of proteasome or proteases. Also provided are compounds and compositions useful as ER-stress aggravating agents, methods for screening, selecting, identifying and designing the same and methods for treating diseased conditions by inducing apoptosis through specific and selective aggravation of ER-stress.

  • Publication number: 20150209361
    Abstract: A pharmaceutical composition and method for treating brain cancer are provided. The method includes administering to a patient in need thereof an effective amount of one or more compounds that include moclobemide, clorgyline, clorgyline's Near-infra-red dye Monoamine Oxidase Inhibitor (NMI), and MHI 148-clorgyline, and their salt thereof. The composition and method are particularly effective in reducing the size of glioblastomas that are temozolomide (TMZ) resistant.

  • Publication number: 20140288115
    Abstract: It is discovered that noscapine is effective in treating temozolomide (TMZ)-resistant brain cancer. Provided are compositions and methods of treating brain cancer patients, in particular those that are TMZ-resistant. The patients are treated by administration of a therapeutically effective amount of noscapine or an analog thereof. In certain aspects, TMZ is also administered to the patients. Examples of brain cancers include glioma such as glioblastoma multiforme.

  • Patent number: 8827986
    Abstract: A remotely activated piezoelectric pump for delivery of biological agents to the intervertebral disc and spine in order to achieve spinal fusion. A spinal pump is implanted on the vertebrae of a patient and a spinal cage is inserted in between two adjacent vertebrae after removal of the vertebrae disc. A piezoelectric motor drives the pump and pushes osteogenetic agent through the spinal cage and into a sponge disposed within the cage. The pump is charged by an external removable induction belt worn by the patient. Delivery duration and delivery frequency may be changed before implantation of the spine pump according to the specific needs of the patient. The current device employs a mathematical model that enables the regulation as well as attenuation of the bone fusion process by extending and generalizing the model to enhance and optimize the delivery of osteogenetic agent in a regulated manner.

  • Patent number: 8323269
    Abstract: A magnetically controlled pump is implanted into the cerebrospinal fluid of a patient and delivers a plurality of medicating agents at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled lumen, intratumoral catheter which will be implanted. Spinal fluid drawn from the patient is analyzed. Medication is delivered on a continuous metronomic basis into the CSF via an internalized pump. CSF is removed and analyzed for VEGF and other cytokines via spectrophotometer analysis or a lab on a chip. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.

  • Patent number: 8323270
    Abstract: A magnetically controlled pump is implanted into the brain of a patient and delivers a plurality of medicating agents mixed with Avastin at a controlled rate corresponding to the specific needs of the patient. The current invention comprises a flexible double walled pouch that is formed from two layers of polymer. The pouch is alternately expanded and contracting by magnetic solenoid. When contracted, the medicating agent Avastin is pushed out of the pouch through a plurality of needles. When the pouch is expanded, surrounding cerebral fluid is drawn into the space between the double walls of the pouch from which it is drawn through a catheter to an analyzer. In cases where a tumor resection is not performed, an intratumoral catheter will be implanted. Cerebral fluid drawn from the patient is analyzed. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller.

  • Publication number: 20120245565
    Abstract: A method for utilizing a controlled pump implanted into a patient connected to a multilumen catheter allowing delivery to and sampling from the brain or other organ for treatment of a cancer. The pump delivers a plurality of medicating agents, including viral and non-viral vectors for gene therapy and cell therapy at a controlled rate, corresponding to the specific needs of the patient. A catheter is implanted in or adjacent to the tumoral region. Fluid drawn from the tumor region to the pump via the multilumen catheter is analyzed within the pump by various biofeedback sensors. The operation of the apparatus and hence the treatment is remotely controlled based on these measurements and displayed through an external controller. The method allows localized delivery of gene and cell therapy to a solid tumor or tumoral region, or to any other treatment area of interest within the patient.
