Title: Manipulation of protoporphyrinogen oxidase enzyme activity in eukaryotic organisms
Inventor: WARD ERIC RUSSELL
IPC: C12Q1/68
Filed: 1995-06-08
Abstract: The present invention provides novel eukaryotic DNA sequences coding for native protoporphyrinogen oxidase (protox) or modified forms of the enzyme which are herbicide tolerant. Plants having altered protox activity which confers tolerance to herbicides are also provided. These plants may be bred or engineered for resistance to protox inhibitors via mutation of the native protox gene to a resistant form or through increased levels of expression of the native protox gene, or they may be transformed with modified eukaryotic or prokaryotic protox coding sequences or wild type prokaryotic protox sequences which are herbicide tolerant. Diagnostic and other uses for the novel eukaryotic protox sequence are also described. Plant genes encoding wild-type and altered protox, purified plant protox, methods of isolating protox from plants, and methods of using protox-encoding genes are also disclosed.

Abstract: A drum washer-drier includes a drum rotating about a horizontal rotary axis, a water tank including a drum, and an outer tank resiliently supporting the water tank. A plurality of suspending rods are suspended from an upper inner surface of the outer tank, and the water tank is resiliently supported by providing compression springs between spring-receiving portions at lower ends of suspending rods and support-receiving portions of the water tank. Further, a damper generating a sliding resistance as the spring is expanded/compressed is provided at the lower end portion of each suspending rod. At the time of dehydration, the drum is rotated for a prescribed time period at a rotation speed higher than a critical rotation speed of a fluid balancer, but lower than a resonance rotation speed caused by resilient support, and thereafter high-speed rotation starts.      A structure for protecting the fluid balancer formed of synthetic resin during drying is also disclosed.

Filed: 1997-02-05
Abstract: A horizontal moving and stirred bed reactor for heat treating particulate material comprises a housing having an inlet for admitting therein the particulate material to be heat treated and an outlet for discharging the heat treated material, at least one tray disposed horizontally inside the housing between the inlet and outlet and having a support surface for supporting a bed of the particulate material, a heating system for heating the bed of particulate material on the support surface, and a conveyor system for moving the bed of particulate material while being heated along a predetermined direction on the support surface. The conveyor system includes a plurality of horizontally spaced-apart rake members extending across the support surface transversely of the predetermined direction and each having a plurality of spaced-apart fingers in sliding contact with the support surface. The rake members are moved to displace with the fingers the particulate material along the predetermined direction, the fingers of any one of the rake members being misaligned with the fingers of any other of the rake members and being spaced relative to one another such that the fingers rake across substantially the entire support surface of the tray and constantly stir the particulate material while displacing same, thereby constantly exposing fresh surfaces of the particulate material to heat and increasing heat transfer in the bed. The horizontal moving and stirred bed reactor of the invention can be used not only for pyrolyzing particulate material, but also for drying particulate material and carrying out various reactions requiring heat.

Title: Diagnostic test for proliferative senescence in immune cells
Inventor: EFFROS RITA B
IPC: G01N33/533
Filed: 1995-09-18
Abstract: A method for distinguishing immunologically senescent cells from immunologically non-senescent cells in a cell population comprises the steps of: (1) providing a cell population; (2) reacting the cell population with a monoclonal antibody specific for CD28 antigen, the antibody being labeled with a detectable label, so that the monoclonal antibody binds to cells positive for CD28 antigen, the cells that bind the antibody being immunologically non-senescent, and the cells that fail to bind the antibody being immunologically senescent; and (3) detecting the cells that react with the monoclonal antibody by observing the detectable label bound to the cells, thereby distinguishing immunologically senescent cells from immunologically non-senescent cells and determining any of: (1) the number of immunologically senescent cells in the population; (2) the number of immunologically non-senescent cells in the population; or (3) the proportion of immunologically senescent cells to immunologically non-senescent cells in the population. Typically, the label is a fluorescent label. Typically, the cells are T cells, and a subpopulation of cells that are CD3-positive can be studied. The method can also be used to separate and isolate cells showing immunological senescence from non-senescent cells.
