Abstract: The present invention provides recombinant antibody fragments which include a variable domain which has been modified by the addition of a tail sequence to its C-terminal end. The tail sequence comprises a terminal cysteine residue and an amino acid spacer and does not substantially affect the fragment's target-binding affinity. The present invention also provides pharmaceutical compositions comprising the described antibody fragments and a pharmaceutically acceptable ? carrier and methods of delivering an agent to cells of interest in a subject using the fragments as delivery vehicles. The invention further provides compositions comprising the described antibody fragments for the in vitro detection and measurement of target molecules which bind to the fragments and method of determining the presence or amount of such targets in a biological sample by contacting the sample with such compositions.

Abstract: There is provided a protection structure for a gas cylinder assembly comprising a gas cylinder body and a valve. The gas cylinder body includes a base and a neck to which a proximal end of the valve is connectable in use. The protection structure comprises first and second structural sections, the first section being connectable to the valve such that the second section is spaced from the valve by the first section. Further, in use, the second section is arranged to transfer impact forces to the first section, and the second section is arranged to deform with respect to the second section in response to said impact forces to reduce the peak impact force on the valve.

Abstract: An improved chair back is formed of a molded construction uses multiple mold shots of mold materials to develop different performance characteristics in selected areas of the chair back. The chair back has the appearance of a unitary molded panel, but is formed from multiple mold shots which preferably are performed at multiple stations on a mold tool. By providing multiple mold shots and selected materials to form different areas of the chair back, different performance characteristics are generated including the provision of a peripheral frame providing structural rigidity to the chair back, a lumbar support panel which provides localized support to the lumbar region of the chair occupant, and a thin sheet-like support panel extending between the frame and enclosing the interior region defined between the peripheral frame to provide a more flexible and pliant surface providing more comfortable contact with the occupant's back.
