Abstract: The present invention relates, first, to the discovery, identification, and characterization of novel nucleic acid molecules, that are associated with PBC, Sjögren's syndrome, scleroderma, SLE, autoimmune thyroiditis and various other connective tissue disorders. The novel nucleotide sequences of the present invention are retroviral in origin and are indicative of a PBC retrovirus which bears a strong correlation with PBC. The present invention is based, in part, on the Applicant's data which is the first evidence to suggest that PBC patient's tissue may harbor a transmissible agent. The association of a retroviral infectious agent with PBC was first demonstrated by Applicants in vitro by co-culture of periportal lymph nodes derived from patients at time of transplantation and healthy biliary epithelium cells. The Applicant's discoveries as described herein, report the characterization of PBC-associated infectious agent as retroviral as demonstrated by electron microscopy and immunoblot reactivity. In addition, Applicants have characterized novel nucleotide sequences which are associated with the PBC-associated retrovirus.

Patent JP-2003512920-A (JP)
IPC: B01D25/00
Filed: 2000-10-20
Abstract: In a filter press, a stack of vertically oriented, horizontally displaceable filter plates enclose filter chambers therebetween. The filter plates are successively moved relative to each other from a closed pressing position, through a pressure relief position, to an open discharge position. At least one connecting element is connected to each filter plate, and is movably coupled to the respective adjacent filter plate by a coupling pin, which slides in a specially configured groove of the connecting element. In the relief position, a respective coupling pin is stopped against an intermediate blocking surface of the groove of the connecting element of the next adjacent filter plate, thereby preventing further horizontal displacement. By unlatching the connecting element, the coupling pin can then slide to a stop surface of the groove, to allow the adjacent filter plates to be displaced farther into the open discharge position.
