128 11

Abstract:

This invention relates to a laryngoscope with an improved double-angle blade or spatula which has three segments lengthwise. The first segment extends in a direction substantially normal to the handle to a first bend, at which the blade or spatula is bent toward the handle through an angle of 20 degrees. The second segment extends in a new direction to a second bend inward through an angle of 30 degrees, forming a third segment which extends to the distal tip. A small cylindrical bulb is superposed adjacent to and parallel to the top edge, near the end of the second segment. This is energized by batteries in the handle.

Abstract:

A modular, small molecule regulated single chain variable fragment (scFv) fusion protein is disclosed. The scFv fusion protein comprises a ligand binding protein fused to a protein that binds to an exogenous control molecule, wherein the scFv fusion protein is directly regulated by the control molecule. Binding of the control molecule to the ligand binding protein induces a change in the affinity of the scFv for a target antigen. Methods of using the fusion protein to treat diseases such as cancer are also described.
