Abstract: An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members is connected to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member which is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member. The monopolar element is connected to the source of electrosurgical energy and is selectively activateable independent of the bipolar mode.

Title: Method, composition and kit for antigenic binding of norwalk-like viruses
Inventor: JIANG XI
IPC: G01N33/569
Filed: 2003-06-02
Granted: 2012-05-29
Abstract: A method for detecting a Norwalk-Like Virus (NLV) in a biological sample, comprising the steps of: obtaining a biological sample suspected of containing a NLV; contacting the biological sample with at least one human histo-blood group antigen to allow formation of a complex of the NLV with the antigen; and detecting the antigen NLV complex. The antigen-NLV complex can be detected by contacting the NLV-antigen complex with a NLV antibody that binds at an epitope of the NLV, and detecting the NLV antibody. The invention also includes a method for identifying compounds, and the compounds, that can inhibit the binding between a Norwalk-Like Virus (NLV) and a histo-blood group antigen. The method includes the steps of contacting the NLV target with a compound; subsequently contacting the NLV with a standard compound that is known to be bound at a determinant binding site of the NLV; and determining whether the binding of the standard compound is decreased in the presence of the test compound, the decrease in binding being an indication that the test compound inhibits the binding activity of the NLV with the standard compound. In preferred embodiments, the standard compound is a histo-blood group antigen.
