Abstract: In accordance with the present invention, it has discovered that histone deacetylase associates with hormone receptor complexes and contributes to the repression thereof. It has further been discovered that exposure of a repressed system to histone deacetylase inhibitors relieves this repression.  Thus, histone deacetylase inhibitors have been found to be useful for the activation of genes responsive to hormone receptors. In accordance with another aspect of the invention, formulations useful for modulation of hormone-mediated processes have been developed. In addition, assays have been developed for the identification of compounds useful to modulate the above-described processes.

Abstract: A package (10) for maintaining the predetermined desired non-planar, three-dimensional shape of the distal tip (14) of a flexible catheter, cannula, sphincterotome or the like (12) includes a non-relaxing mounting tray (18) with a non-planar, three-dimensional structure (20) restricting movement of the distal tip (14), and a non-relaxing cover (26) detachably secured to the tray (18), trapping part and only part of the distal tip (14) against the three-dimensional structure (20) of the tray (18). The package (10) also includes a particularly configured non-relaxing insert (38) removably received in a bore (16) in the distal tip (14). The tray (18), cover (26) and insert (38) together support the distal tip (14) throughout its entire length. The structure (20) of the tray (18) includes a ramped, relatively tightly arced groove (24) on which the distal tip (14) lies. The cover (26) lies over at least the ramped, arced groove (24) and includes a pair of notches (30) receiving the distal tip (14) therethrough. When the cover (26) is detached from the tray (18), at least the distal tip (14) can be freely perpendicularly withdrawn from the tray (18). The package is particularly useful for maintaining the distal tip (14) in a shape particularly adapted for the performance of a sphincterotomy. The package (12) prevents the relaxation or change of the predetermined desired non-planar, three-dimensional shape of the distal tip (14) of the catheter, cannula, sphincterotome or the like (12) during sterilization and storage. The insert (38) and the combination of the tray (18) and the cover (26) are separately useful for this purpose.

Abstract: A grinding mill has a rotating container (40) into which particulate material is fed. The container is rotated above critical speed to form a layer which is retained under high pressure against the container inner surface. Shearing discs (58) mounted inside the container induce shearing of the layer to promote particle fracture by shearing and abrasion in the pressurised layer. Fine ground material travels axially to the container discharge end (64). In one form of the invention, the container is rotated at sufficient speed to form a series of solidified zones (70) alternated with stirred zones (72) next to non-rotating shearing discs (58). These solidified zones act as solid discs rotating with the container.

Abstract: A cam shaft bearing insert is provided for use in a cam shaft support bearing for operably supporting a cam shaft in an internal combustion engine. The engine includes a cylinder head with bearing support towers that operably support journals on the cam shaft at multiple aligned bearing locations. Each bearing support tower has an oil port for passing oil to the associated journal. The bearing insert further has a thin-walled cylindrical sleeve formed from thin flat stock into a cylindrical tubular shape that is adapted to fit into one of the bearing support structures and form a bearing surface suitable for supporting the cam shaft. The sleeve has an outer surface with an outwardly deformed area configured to non-rotatably engage the one bearing support structure and has an aperture therein so that, when the aperture is aligned with the oil port of the one bearing support structure, oil can pass from the oil port to the associated bearing location.  The sleeve includes a longitudinal slit allowing the sleeve to flex outwardly to slip onto a journal of the cam shaft and then flex inwardly into one of the bearing support structures of the cylinder head. A broaching tool is provided that is adapted to be linearly pulled through the aligned bearing locations to reform the bearing support structures in preparation for receiving one of the bearing inserts. A method of repair includes enlarging at least one cam shaft support bearing to an oversized condition, such as by using the broach, repairing the oversized cam shaft support bearing by filling voids and galled areas with a thermal setting polymer, as needed, positioning a bearing insert on the cam shaft, and positioning the cam shaft including the bearing insert in the cam shaft support bearing with the cam shaft being rotatably supported in the bearing insert and the bearing insert being secured to the oversized cam shaft support bearing.
