Abstract:
The invention relates to mutations in ErbB2 gene products. The mutations described are identified in human tumours of natural origin. These mutations are associated with cancerous phenotypes and can be used as a basis for the diagnosis of cancer, cancerous cells or a predisposition to cancer in human subjects, selection of appropriate anti-cancer therapy and the development of anti-cancer therapeutics.
Abstract:
The design and construction of past articulated pistons has failed to include the most efficient cooling reservoir for transferring heat from the piston to the coolant. The present invention overcomes these problems by using an annular cooling recess of a precisely defined cross sectional shape and volume and a baffle plate fixedly sealingly attached in heat conducting relationship to the piston member to form a cooling gallery. The baffle plate has an opening therein and an upwardly extending raised portion to preestablish a trapped volume of coolant therein. The assembly, positioning of the plate and the preestablished trapped volume insures high efficiency of the coolant to absorb heat through the scrubbing action of the coolant on the recess and the heat absorbed by the trapped coolant because of the heat conducting relationship of the plate and the piston member.
