Abstract: The invention relates to a mechanochemical engine capable of converting chemical work to mechanical work. The mechanochemical engine comprises an elastomeric material capable of reversibly contracting and relaxing by an inverse temperature transition induced by changes in the chemical potential of a surrounding medium. Examples of elastomeric materials and their elastomeric units that may be used in the mechanochemical engine are described.
Abstract: A viral vector for the integration and expression of at least one heterologous gene in fowl pest cells consists wholly or in part of the proviral genome of fowl pest erythroblastosis or of a related virus in which said heterologous gene(s) replace(s) the v-erbA gene and/or the v-erB gene. Said gene(s) is(are) controlled either by an LTR promoter of the same virus, in which case the heterologous gene(s); mimics(s) the gene(s) it(they) replace, or by a heterologous promoter, in which case the additional att sequence is situated upstream of said heterologous promoter.

Abstract: The present invention provides an improved assay for measuring thyroxine uptake by thyroxine binding globulin in which thyroxine binding globulin (TBG) activity is measured directly. The method comprises combining a sample in an aqueous solution with an enzyme donor (ED) conjugated to an analogue of polyiodothyronine that competes with thyroxine for thyroxine binding globulin binding sites. An enzyme acceptor (EA) characterized by providing a modulated enzyme activity in relation to the amount of TBG activity is combined with an enzyme donor and sample in an aqueous solution. The amount of enzyme activity in comparison to a control solution having a known amount of available TBG binding sites is determined.
Abstract: A method for detecting the presence of a high-molecular-weight analyte, which uses a variation on complementation assays, comprising (1) providing an enzyme donor (ED)complex comprising ED coupled to an analyte-specific binding molecule, wherein the ED complex retains measurable complementation activity such that active .beta.-galactosidase is formed in the presence of an enzyme acceptor (EA); (2) contacting the ED complex and EA in the presence of a sample suspected of containing a high-molecular-weight analyte that reacts specifically with the analyte-specific binding molecule; and (3) relating the presence of the analyte in the sample to the formation of active .beta.-galactosidase enzyme.

Abstract: A capillary stop-flow junction located in a housing at an end of a capillary passageway used to transport a liquid and at the beginning of a non-capillary internal chamber in the housing, in which the stop-flow junction contains an improvement which comprises 1) means for selectively trapping a gas in the capillary passageway and non-capillary chamber, wherein when the means for trapping is activated and the liquid enters the capillary passageway, the gas is compressed by the liquid as the liquid flows through the capillary channel and stops flowing at the stop-flow junction; or 2) a stop-flow nozzle surrounding the capillary passageway and projecting into the chamber; or 3) the stop-flow junction being formed from a single housing body member; or 4) a rupture junction in the capillary pathway, wherein the rupture junction is a stop-flow junction providing less maximum available back pressure than the capillary stop-flow junction.

Abstract: A composition that expands against an exerted pressure, which comprises a polymeric material having an inverse temperature transition in the range of liquid water, wherein at least a fraction of the monomers in the polymer contain a hydrophobic group that is present in an amount sufficient to provide PdV/dS for the polymer of at least 0.2.degree. K. The composition can be used in a variety of different application to produce mechanical work or cause chemical changes in a sealed environment by varying the pressure on the composition, with the degree of mechanical or chemical change being controlled by selection of the number, hydrophobicity, and size of the hydrophobic group and the presence or absence of reactive functional groups in the polymer.
