Abstract: A system, method, and computer program product for registering two or more patient images for change assessment over time. An example aspect is configured to: obtain a new image of an area with an image capture system; obtain a reference image of a similar area; perform pre-processing of the new image and the reference image; perform a coarse alignment of the new image and the reference image; perform a high-resolution estimate; perform a high-resolution alignment; cross-check the at least one-point match to eliminate false matches and confirm correct matches of the high-resolution new image and the high-resolution reference image; perform segmentation of the high-resolution new image and the high-resolution reference image; perform analysis on at least one lesion in the high-resolution new image and the high-resolution reference image; and display a result of the analysis on a validator.

Abstract: A reusable fitting, connector assembly and kit. The reusable fitting includes a barb portion, a threaded portion, a tightening portion, a connector portion and a substantially smooth cylindrical bore extending through the barb portion, threaded portion, tightening portion and connector portion. The tightening portion is disposed proximate to the threaded portion and includes least two parallel tightening surfaces. The connector assembly includes the fitting, a nut and a crimp sleeve. The kit includes the connector assembly and at least one wrench.

Abstract: The amount of active Robo expressed on a cell is modified by modulating the effective amount of a Comm polypeptide in contact with the cell, whereby the amount of expressed active Robo is modulated inversely with the modulation of the effective amount of the Comm polypeptide in contact with the cell. In a particular embodiment, the Comm polypeptide is provided to the cell by exogenously in a pharmaceutically acceptable composition. In another aspect, the invention provides methods of screening for agents which modulate Robo-Comm interactions. These methods generally involve forming a mixture of a Robo-expressing cell, a Comm polypeptide and a candidate agent, and determining the effect of the agent on the amount of Robo expressed by the cell.
