Title: Multivalent repressor of gene function
Inventor: BACHMAYER HELMUT
IPC: C12N15/49
Filed: 1990-05-23
Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes are described, having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used.     Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species.     Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g.   HIV-1 infection.

Inventor: ROBAR SHELDON
IPC: F02B75/02
Filed: 1990-12-31
Abstract: An engine system using refrigerant fluid is cap-able of utilizing the heat produced by an external high-efficiency hydrocarbon fuel combustion process.  The heat from that process is utilized to transform the refrigerant fluid from a liquid state to a gaseous state in a cycle which includes extracting work from the fluid in the gase-ous state in a high-compression-ratio piston engine.  The cycle further includes transforming the fluid in the gase-ous state back to the liquid state in a condenser, and then feeding that fluid under pressure to a heating chamber where the combustion process heat again returns it to the gaseous state at high pressure and temperature.  The engine system has a higher efficiency than hydrocarbon fuel com-bustion engines, and has particular application to use in automobiles.  One preferred refrigerant fluid for this engine system is 2,2,Dichloro-1,1,1,Trifluoro-Ethane.
