Title: Targeted cleavage of rna using eukaryotic ribonuclease and external guide sequence
Inventor: YUAN YAN
IPC: A61K38/00
Filed: 1993-04-28
Granted: 1999-01-12
Abstract: It has been discovered that any RNA can be targeted for cleavage by RNAase P from eukaryotic cells, for example, human HeLa cells, using a suitably designed oligoribonucleotide ("external guide sequence", or EGS) to form a hybrid with the target RNA, thereby creating a substrate for cleavage by RNAase P in vitro. There are two classes of EGS that can target RNA for cleavage human RNAase P. These are prepared by transcription from a small DNA fragment that contains a sequence coding for an RNA that can assume a tRNA-like secondary structure. In the first class, the structure lacks at least the first thirteen nucleotides from the 5' terminus of the tRNA-like sequence, the anticodon stem and loop, the variable loop or part of the variable loop. The most efficient EGS with human RNAase P is the EGS in which the anticodon stem and loop was deleted. In the second class, the EGS has changes in both the equivalent of the T-loop and the anticodon stem of the tRNA-like segment of the EGS. Methods are also disclosed to randomly select and to express a suitable EGS in vivo to make a selected RNA a target for cleavage by the host cell RNAase P, thus preventing expression of the function of the target RNA. The methods and compositions should be useful to prevent the expression of disease-causing genes in vivo.

Granted: 2005-03-29
Abstract: A software system simulates and optimizes a processing plant design. The software system includes a plurality of equipment models for simulating each piece of equipment in the processing plant design. A sequential modular simulation routine executes the equipment models in a first mode to define a first set of values of the operating parameters of the processing plant design. An optimization routine executes the equipment models in a second mode. The optimization routine utilizes the first set of values for the operating parameters from the sequential simulation routine and subsequently determines values of the operating parameters at which the processing plant design is optimized. The equipment models after execution by the sequential simulation routine and optimization routine store the first and second sets of values for the operating parameters in a common plant model file. Hence, the plant model file holds values computed during the sequential simulation routine as well as those computed during the optimization routine.

Abstract: A tire tread that is applicable to retread a worn tire carcass. The tire tread includes a cured tread portion having a first shoulder and a second shoulder. A first uncured wing portion extends from the f first shoulder and a second uncured wing portion extends from the second shoulder. Further, an end section at each end of the tire tread portion is uncured. When the tire tread is wrapped around the tire carcass to be formed to the tire carcass and form a tire retread, the first and second wing portions extend down the side walls of the tire carcass and the uncured end sections of the tire tread contact each other.     The tire carcass is placed within an autoclave, and the autoclave is heated under pressure such that the tire tread is cross-linked to the tire carcass. During the autoclaving step, the uncured wing portions are cured and cross-linked to the side walls of the tire carcass, and the uncured end portions are cured and cross-linked to each other. A mold segment is positioned within the tire tread pattern where the end sections of the tire tread meet in order to prevent the tire tread pattern from being damaged at the uncured end sections during the autoclaving process.
