Abstract: The present invention relates generally to the field of accessories for plumbing fixtures having openings for a drain. More specifically, the present invention relates to a screen or guard device having a plurality of vertical members, which are connected to a plurality of horizontal cross members. The device can then be placed into the interior of a plumbing fixture enclosure such that the vertical members contact the sides of the interior area of the fixture and the horizontal cross members prevent an object from being thrown into the fixture and lost down the opening.

Abstract: A system and method of impingement cooling are presented. A cooling apparatus for cooling food product containers to a predetermined temperature includes a thermal treatment apparatus and a container support apparatus. The thermal treatment apparatus includes an air duct, a plurality of plenums coupled to the air duct, and a fan. The air duct is adapted to receive air from a first area where food products are kept at a temperature below the predetermined temperature. The plenums have orifices and the fan is adapted to push air received from the first area into the plurality of plenums. The container support apparatus includes a plurality of container supports adapted to support food product containers. The container support apparatus is positioned to interleave the food product containers with the plurality of plenums. Air discharged through the orifices impinges on food product containers supported by the container support apparatus.

Abstract: A high throughput virus in vitro infectivity assay method comprising growing cells in a multi-well format, infecting the cells with intact virion incubated with a test agent, and measuring expression of at least one viral nucleic acid sequence in the cells. The method also preferably comprises incubating intact virion without test agent to define a control. The cells are preferably human keratinocyte cells grown in monolayers. The viral nucleic acid sequence will generally comprise viral mRNA. In one preferred embodiment, the intact virion comprise Human Papilloma Virus, and more preferably Human Papilloma Virus-11. Measuring expression is generally carried out by releasing the viral mRNA from the cells by lysis, amplifying the mRNA as CDNA via RT-PCR, and detecting amplicons with specific probes. Cell lysis may be carried out by heating or by treatment with detergent.

Abstract: A modular tray accumulator system includes a number of horizontal and vertical stacked conveyors arranged in a portable module. Each conveyor operates independently of the others. The system may be mechanically raised or lowered to any desired height, or may be moved between different floors as a unit. In a first embodiment, each conveyor is activated when a tray is placed on the input end of the conveyor, and moves a preselected distance forward. In a second embodiment, the trays are moved forward by variable friction drive.

Abstract: Novel adenocarcinoma binding human monoclonal antibody binds preferentially with ADCA antigens and is useful in diagnostic and imaging methods for identifying and locating adenocarcinoma cells, and in therapeutic methods to reduce the reproduction of adenocarcinoma cells. The novel ADCA antigen is useful in methods for diagnosing the presence of adenocarcinoma. The antigen, antibodies, hybridoma, reagents, therapeutic agents and methods of use are aspects of the invention.

Abstract: Sensitive proteins in human biological secretion samples are preserved by dispersing them in an aqueous solution containing from 0.05 to 0.5M of a buffer which is effective to maintain the solution pH within the range of from 6.5 to 8.0; from 0.1 to 10 wt. % of a non-immune animal protein selected from the group consisting of albumin, ovalbumin, casein, glycoprotein and mixtures thereof; from 40 to 2000 kallikrein units/mL of an enzyme inhibitor of trypsin, chymotrypsin, kallikrein or plasmin; and from 0.01 to 0.1 wt. % of a bacteriostatic agent. The solution preferably also contains from 5 .mu.M to 1 mM of a protease inhibitor; and from 1 to 10 mM of a chelating agent. Optimally, the enzyme inhibitor is aprotinin, the protease inhibitor is phenylmethylsulfonylfluoride, the non-immune animal protein is bovine serum albumin, and the protease inhibitor is phenylmethylsulfonylfluoride. 0.0 to 0.15 mM of a water-soluble non-interfering salt, such as NaCl, may be desired.

Abstract: A method is provided for testing for particular antibodies in the serum of a patient. The antibodies may be those of systemic lupus erythematosus and may constitute IgG and IgM immunoglobulins. The IgG and IgM immunoglobulin may be individually labeled radioactively.An antigen (such as DNA) may be attached to a support such as sepharose. The attachment may be facilitated as by irradiation with ultraviolet light. The DNA may be single stranded or double stranded. When double-stranded DNA is used, single-stranded portions in the double strands may be removed as by a suitable enzyme.The particular antibodies may be attached to the antigen such as the supported DNA. An assay may then be provided to determine the attachment of the particular antibodies to the supported DNA.
