Title: Assessing the condition of a joint and devising treatment
Inventor: ALEXANDER EUGENE J
IPC: A61B5/055
Filed: 2001-09-14
Abstract: Methods are disclosed for assessing the condition of a cartilage in a joint,  particularly a human knee. The methods include converting an image such as a n MRI to a three dimensional map of the cartilage. The cartilage map can be correlated to a movement pattern of the joint to assess the affect of moveme nt on cartilage wear. Changes in the thickness of cartilage over time can be determined so that therapies can be provided. Information on thickness of cartilage and curvature of cartilage or subchondral bone can be used to plan  therapy. Information on movement pattern can be used to plan therapy.</SDOAB >

Title: A retroviral immunotherapy
Inventor: ASHDOWN MARTIN LEONARD
IPC: A61P31/12
Filed: 2001-08-16
Abstract: The present inventor has noted that at least two populations of immune cells  are produced in response to retroviruses which infect mammals. More particularly, the immune system of a mammal infected with a retrovirus is capable of mounting an immune response against the virus through a group of cells herein generally referred to as "effector cells", however, a second population of cells are also produced which regulate the "effector cells", herein generally referred to as "regulator cells", limiting the mammals' ability to effectively control or eradicate the retroviral infection. Accordingly, the present invention utilizes these observations to provide methods for treating a mammal with a retroviral infection.
