  • Publication number: 20210233330
    Abstract: There is provided a system and method for applying markings to a three-dimensional virtual image or virtual object, the system comprising a physical stylus, a surface, and a virtual or augmented reality display. A virtual space is displayed by the virtual or augmented reality display. The virtual space includes a three-dimensional target object; at least one plane, including a tracking plane, the tracking plane corresponding to the surface; and a virtual stylus in a virtual reality view, or the physical stylus in an augmented reality view. A position of the virtual stylus or the physical stylus relative to the tracking plane is correlated to an actual position of the physical stylus relative to the surface; and a cross-section of the target object is displayed on the tracking plane where the tracking plane intersects the target object.

  • Patent number: 10828346
    Abstract: There are provided compositions and methods for modulating stem cell division decisions, in particular, division symmetry. It has been demonstrated that wnt7a acts through frizzled-7 receptor expressed on the surface of adult stem cells, e.g. satellite stem cells, to activate the planar cell polarity (PCP) pathway, thereby promoting symmetrical expansion of stem cells. The compositions and methods of the invention are useful, for example, in modulating stem cell division symmetry in vitro and in vivo, in replenishing and expanding the stem cell pool, and in promoting the formation, maintenance, repair and regeneration of tissue.

  • Patent number: 10172569
    Abstract: A system and method are provided that employ the variability of physiological waveforms to estimate the time to death after WLST, or time to inadequate organ perfusion. From the variability data one can derive an index subsequently used to determine the probability of death (or inadequate organ perfusion) within a given time frame in an automated fashion from bedside monitors in the intensive or post-anesthesia care unit. The resulting variability index can also be combined with the clinical variables used in other death prediction tools to enhance the performance and outcome when compared to existing models. In at least one implementation, variability monitoring at the bedside could be used to provide estimates of the probability that a patient will die within a certain time frame after WLST. These estimates could be used to reduce the distress of the patients' families, as well as optimize the use of resources surrounding donation.
