  • Patent number: 12529034
    Abstract: The WNT-ACTIVATED ADIPOSE-DERIVED STEM CELL APPARATUSES, METHODS AND SYSTEMS (hereinafter “WAADSC”) disclosed herein in various embodiments provide for production of an isolated and enriched population of mesenchymal stem cells that have an active Wnt signaling demonstrated by the elevated expression of Lgr5 marker and/or Nestin in more than 50% of the population. Such an autologous cell population may, in embodiments, be injected into cerebral ventricles of patients with neurodegenerative diseases to yield therapeutic results, such as halting the progression of certain conditions and/or ameliorating specific symptoms thereof.

  • Patent number: 9198597
    Abstract: Kits and methods for the treatment of certain types of cancers, specifically various primary brain cancers. In some embodiments, treatment is directed toward the known areas of cancer cell infiltration and along pathways of likely migration ahead of established areas of cancer cell infiltration. In some embodiments, cancer cells are targeted where they have likely spread, but yet remain undetected. Some embodiments relate to a means of automatically directing radiological analysis along likely pathways of cancer cell migration to precisely determine the extent of detectable cancer spread. In some embodiments, treatments are directed to a predetermined distance along such pathways.

  • Publication number: 20070050216
    Abstract: The present invention provides systems and methods to realize the potential benefit of portable storage devices by taking advantage of standard PCs including an optical disk drive capable of reading an optical disk, such as a CD or a DVD, cost effective optical disks, and the Internet. In a preferred embodiment, an individual patient provides personal data to a healthcare service center. The healthcare service center then creates a portable optical disk for the patient to carry, if he/she so desires. The personal data that is written onto the portable optical disk is stored on a database management server database and is readable and updateable by the individual patient using his/her PC with an optical disk drive and connected to the Internet. The individual patient can choose to update his/her personal data on the portable optical disk and can receive a new portable optical disk that includes the update.
