Abstract: A device and method for treating a hone includes a bone plate including first and second portions joined to one another via a connecting portion, a rigidity of the connecting portion being less than rigidities of each of the first and second portions in combination with a first sensor mounted on the first portion measuring strain on the first portion and a second sensor mounted on the second portion measuring strain on the second portion.

Abstract: The invention provides methods and systems for detecting a biomarker in a synovial fluid wherein the system also includes a control to ensure that the test sample is indeed synovial fluid. The biomarkers and the control for synovial fluid can be identified using proteomic methods, including but not limited to antibody based methods, such as an enzyme-linked immunosorbant assay (ELISA), a radioimmunoassay (RIA), or a lateral flow immunoassay.

Abstract: A linear actuator for pumping comprising a stator having an inner opening, a shaft having a plurality of permanent magnets spaced linearly in the axial direction, the shaft disposed in the stator opening and configured to reciprocate linearly in the axial direction relative to the stator, the stator comprising a first stator assembly having a plurality of pole sections spaced linearly in the axial direction and a plurality of coils disposed therebetween, a second stator assembly having a plurality of pole sections spaced linearly in the axial direction and a plurality of coils disposed therebetween, a bearing assembly positioned axially between the first stator assembly and the second stator assembly, and the bearing assembly having a width that is a function of the spacing of the plurality of pole sections of the first stator assembly and the second assembly and the spacing of the plurality of permanent magnets of the shaft.

Abstract: A method of diagnosing the source of local, acute inflammation has been developed based on the discovery that white cells have different patterns of gene expression, and therefore protein markers, depending on the origin of the inflammation. These differences can be readily accessed by analysis of the white cells obtained at a site to be analyzed, for example, in the synovial fluid of a knee. The analysis, by comparison with the analysis of white cells present in known conditions, can be used to differentiate between inflammation due to bacterial infection, arthritis or gout, for example. The examples demonstrate differential gene expression in cells present in synovial fluid biopsies from patients with confirmed bacterial infection as compared to patients with aseptic loosening or patients with inflammation due to gout.

Abstract: This invention relates to field of screening and diagnosing adverse local tissue reaction (ALTR) in a subject who has received a joint replacement by measuring the level of a nucleic acid or protein biomarker that are elevated in patients suffering from ALTR, even those with no symptoms. The early diagnosis of the ALTR can lead to its treatment and thus, the prevention of implant failure caused by the ALTR. The elevated proteins and genes are also the basis for treatment for ALTR and provide targets for drug development and basic research.
