Abstract: A system and method for translating a patient table is described. The described patient table includes a linearly translatable portion, a drive screw assembly, a power transmission assembly, and a drive train. The translatable portion is configured to be positioned in a plurality of selectable positions between a fully inserted position and a fully extracted position. The drive screw assembly includes a drive nut and a screw member. The drive nut is fixedly coupled to the translatable portion of the patient table and threadily engaged to the screw member. The screw member is drivingly coupled to the power transmission assembly. The drive train is configured to drive the translatable portion of the patient table at a predetermined insertion force in the insertion direction, and a predetermined extraction force in the extraction direction. The predetermined extraction force is greater than the predetermined insertion force.

Abstract: Described is a method for screening for alterations in exocytosis of a population of cells. The cells are sorted by a FACS machine by assaying for alterations in at least three of the properties selected from the group consisting of light scattering, fluorescent dye uptake, fluorescent dye release, annexin granule binding, surface granule enzyme activity, and the quantity of granule specific proteins. Methods for screening for bioactive agents capable of modulating exocytosis in a cell are also described. The methods provide for reduced background and increased specificity without increasing the time or steps involved in assaying for exocytosis.

Abstract: The invention provides shuttle vectors, and methods of using shuttle vectors, capable of expression in, at least, a mammalian cell. Furthermore, the shuttle vectors are capable of replication in at least yeast, and optionally, bacterial cells. Also provided is a method wherein yeast are transformed with a shuttle vector as provided herein.
