Patent NZ-720683-A (NZ)
Title: A dental implant
Inventor: MCDONALD SIMON P
IPC: A61C8/00
Filed: 2015-10-09
Abstract: A dental device comprises: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced linearly away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core presses into the expandable anchor without rotation to lock the plurality of joined segments in their expanded configuration. At least a first rail on the core is received by a corresponding expandable anchor slot to align the core and expandable anchor.
Patent NZ-723237-A (NZ)
Title: Anticancer adjuvant composition containing rip3 expression promoter as active ingredient, method for screening for anticancer adjuvant enhancing sensitivity of anticancer drug by promoting rip3 expression, and method for monitoring sensitivity of anticancer drug
Inventor: KIM YOU SUN
IPC: A61P35/00
Filed: 2014-11-25
Abstract: The present invention relates to an anticancer adjuvant pharmaceutical composition containing a receptor-interacting protein kinase-3 (RIP3) protein expression promoter or activator as an active ingredient. In addition, the present invention provides a method for enhancing cancer cell death, by administering, to cancer cells, a RIP3 protein expression promoter or activator and an anticancer drug in combination. Additionally, the present invention relates to: a method for screening for an anticancer adjuvant which enhances the sensitivity of an anticancer drug by promoting RIP3 expression; and a method for monitoring the sensitivity of an anticancer drug through whether RIP3 is expressed. Therefore, it is expected that pretreating a demethylating agent so as to induce RIP3 expression and then using a conventional chemotherapeutic agent in a patient lacking RIP3 expression could be an effective treatment strategy. In addition, it is expected that monitoring the sensitivity of an anticancer drug and screening for an anticancer adjuvant enhancing the sensitivity of an anticancer drug in cancer treatment could be an effective strategy.

Title: Technique for more efficiently displaying text in virtual image generation system
Inventor: MILLER SAMUEL A
IPC: G06T15/00
Filed: 2016-06-30
Abstract: Disclosed is a method of operating a virtual image generation system. The method comprises allowing an end user to visualize an object of interest in a three-dimensional scene, spatially associating a text region (which may be displayed) within the field of view of the end user, wherein the text region is spatially associated with the object of interest. A gesture reference is generated associated with the object of interest, and a textual message is generated that identifies at least one characteristic of the object of interest. The textual message is streamed within the text region. Gestural commands are sensed from the end user by detecting an angular position of an anatomical part of the end user, relative to a plurality of different regions of the gesture reference. Streaming of the textual message is controlled in response to the sensed gestural commands, wherein the gesture reference is an annular ring surrounding the object of interest, and wherein a first side of the annular ring forms one of the different regions. A second side of the annular ring opposite of the first side of the annular ring forms another one of the different regions. In one example method, the textual message is streamed within the text region only one word at a time. In another example method, the textual message is displayed in the textual region at least two words at a time while emphasizing only one of the displayed words.

Title: Gaseous contrast media for ultrasound and method of selecting gases for use as ultrasound contrast media
IPC: A61K49/00
Filed: 1992-09-15
Abstract: This invention relates to agents for increasing contrast in an ultrasound image. These agents are in the form of extremely small bubbles or "microbubbles" of specially selected gases. The microbubbles described here have a long life in solution and can be produced in a sufficiently small size to pass through the lungs, thus making it possible to obtain better ultrasound imaging of the cardiovascular system and other vital organs. This invention also relates to a method for the selection of gases from which contrast agents can be produced. The method is based on calculations which use the inherent physical properties of gases and describes means for associating the properties of a gas with the dissolution time for microbubbles contained in the gas.
