Title: Optical tracking cas system
Inventor: DAIGNEAULT EMMANUEL
IPC: A61B19/00
Filed: 2008-11-28
Abstract: A computer-assisted surgery system for tracking an object during surgery comprises two trackable devices secured to two parts of an object. The devices each have optical elements arranged in geometrical patterns. The devices are secured separately to the object so that the devices are at least partially detectable from an overlapping range of directions, so that a combinative geometrical pattern is defined from a combination of at least part of the optical elements from the trackable devices. A sensor unit detects tracking data on any tracked geometrical pattern. A pattern identifier identifies, from known pattern data for the geometrical patterns, which of the geometrical patterns is being tracked. A position and orientation calculator calculates position and orientation of the object as a function of tracking data on an identified geometrical pattern and of a known spatial relation between the identified geometrical pattern and the object. A method for tracking an object is also provided.

Abstract: The ADP-ribosyltransferase, Vip2, exerts its intracellular toxicity in insects by modifying actin and preventing actin polymerization. Due to the nature of this toxin, expression of Vip2 in planta is lethal to the plant. Described herein are methods of making zymogens of toxic proteins that are benign in a non-target organism and are activated in a target organism. Disclosed herein are methods of engineering a random propeptide library at a terminus of a toxic protein and selecting for malfunctional variants in yeast. Using this method a selected proenzyme possesses reduced enzymatic activity as compared to the wild-type Vip2 protein, but remains a potent toxin towards corn rootworm larvae. The Vip2 zymogen can be proteolytically activated by corn rootworm digestive proteases.
