Abstract: A method and device for collecting and testing fecal occult blood which permits multiple analyses of a single fecal sample. The device is a combination of a sampler for collecting the fecal matter and a test slide. The fecal sampler comprises a pocket-like wipe pad for obtaining direct anal stool smears. An insert is disposed in the pocket of the wipe pad. The slide has a profiled opening similar to the design of the wipe pad. This opening acts as a receptacle for the pad when the fecal smear is transferred to the guaiac specimen receiving sheet of the slide. When the slide is closed the insert can be removed from the wipe pad. This design permits an analysis to be done on the specimen receiving sheet of the slide together with a second confirmatory test for human hemoglobin on portions of the insert. The fecal material on the insert is physically removed from the guaiac specimen receiving sheet.

Abstract: The invention relates to a method for cleaning a valve sealing arrangement under dynamic stress, and an apparatus for carrying out said method, each sealing arrangement sealing two spaces from one another by means of two seals, separated from one another, in a serial arrangement, between or in which spaces there is arranged in a moveable manner a valve part whose jacket surface interacts with the seals and thereby prevents fluids overflowing from one space to the other, an annular space, enclosing the valve part, being provided between the seals, which annular space is bounded on the outside by a housing of the valve and which is connected via at least in each case one connection and one outlet opening to the environment of the valve. The invention ensures, inter alia, that even those critical regions of the slots for the seals which can be accessed only with difficulty are reliably subjected to the cleaning agent. In terms of the method, this is achieved, inter alia, in that the seal which comes into contact with the fluid to be sealed off is supplied with cleaning fluid from the spaces on both sides of the contact surfaces, up to its contact surfaces (provided temporarily at the sealing points) with the valve part on the one hand and the housing on the other hand. The apparatus for carrying out the method is characterised, inter alia, in that each seal (70, 71) is edged in each case on its side facing the space inside the valve housing part (1 or 2) to be sealed by a fluid-permeable boundary wall (41), and in that each of the seals has a limited mobility in the direction of movement of the valve part (4). <IMAGE>

Abstract: Two Hepatitis C Virus envelope proteins (E1 and E2) are expressed without sialylation. Recombinant expression of these proteins in lower eukaryotes, or in mammalian cells in which terminal glycosylation is blocked, results in recombinant proteins which are more similar to native HCV glycoproteins. When isolated by GNA lectin affinity, the E1 and E2 proteins aggregate into virus-like particles. Cells bearing a mannose receptor or asialoglycoprotein receptor are capable of being infected with HCV, and supporting culturing of the virus.

Abstract: The method of the invention is applied to a cellular radiotelephone network comprising a mobile, at least two transmitter/receiver stations and a controller of these stations. Information exchanges between the mobile and the stations are of the time-distribution multiple-access type. The controller, via one of the stations, called first station, with which the mobile is communicating, sends an instruction to the mobile, indicating to it that it should interrupt its communication with the first station in order to send a sequence of synchronisation signals to a second station allowing the second station to calculate time advance information, the transmission of this instruction being carried out when the mobile passes from a first cell, corresponding to the geographic coverage of the first station, to a second cell, corresponding to the geographical coverage of the second station. The time advance information calculated is supplied to the mobile. This method is characterised in that the instruction supplied to the mobile is also an indication that the mobile should continue to communicate with the first station immediately after sending this first sequence of synchronisation signals to the second station, and the time advance information calculated is transmitted from the second station to the controller and from the controller to the mobile, via the first station.
