Abstract: A syringe (2) for dispensing a fluid, the syringe including a barrel (4) including a discharge end (10) defining a discharge passage, and a plunger (15) disposed within the barrel, the plunger being adapted to move within the barrel such that the plunger and discharge end define a variable volume chamber within the barrel and the plunger is capable of displacing fluid from the chamber through the discharge passage; wherein the syringe includes a rotational element (20a, 20b, 24a, 24b) adapted to rotate about longitudinal axis of the syringe and which has a first axial orientation relative to the discharge end of the barrel and a first stop is provided on the plunger and/or the barrel which is adapted to limit axial movement of the plunger in the first orientation of the rotational element, and the rotational element has a second axial orientation relative to the discharge end of the barrel in which the first stop is disengaged and movement of the plunger is permitted to a second stop.

Abstract: A composite material for environmental odor control is useful in controlling odors from waste, for example, as an alternative daily cover for landfills and in composting applications. The composite material includes a fiber web and a zeolite containing metals to promote absorption of odorous gas.

Abstract: Structurally modified, closed-ended nucleic acid decoys for the manipulation of cellular or viral replication processes are described. These decoys are resistant to cellular degradation, do not directly interact with host DNA and their structure does not require sophisticated knowledge of target DNA sequence. They have been demonstrated to be effective as transcription factor sequestration agents. By effectively competing for cellular transcription factors, these decoys will interfere with the normal transcription process, effectively turning off protein production and cellular replication. These decoys also have potential similar actions and effects in viruses. These decoys should have an impact in the treatment of cancer, AIDS, and other diseases.
