Inventor: TRAINOR ALAN JONATHAN ANDREW
IPC: H03K5/00
Filed: 2000-07-17
Abstract: The invention comprises a phase shifter reset circuit, for phase shifting an input signal, and includes a phase shifter, for shifting the phase of an input signal by a phase determined by a phase shift reference signal and a resetter, for resetting the phase shift reference signal in response to a trigger signal. Also included is a fixed phase shifter for shifting the phase of the input signal by a predetermined phase shift which is connected in parallel with said phase shifter and a threshold detector circuit set to a threshold level which is substantially equivalent to the voltage level required by the phases shifter to produce the same phase shift as is introduced into the input signal by the fixed phase shifter. A bypass circuit is disposed between the phase shifters and the output and includes a switch for selecting a signal from either the phase shifted input signal or said fixed phase shifted signal. The bypass circuit responds to a switching signal in order to switch from the phase shifted input signal to said fixed phase shifted signal for a predetermined period of time, during which time the trigger signal for resetting the phase shifter is generated, before switching back to the phase shifted input signal. The invention includes a method of resetting a phase shifter. Also included in the invention is a delay locked loop incorporating the phase shifter reset circuit and a method of inserting a delay into an input signal using a delay locked loop according to the invention.

Title: Use of ribozymes for functionating genes
Inventor: WONG JUSTIN G P
IPC: C12Q1/68
Filed: 1999-02-12
Abstract: Novel double stranded DNAs, expression vectors and methods for their use are provided in which the intracellular expression of the double stranded DNAs is used to alter the phenotype of a target cell so that the function of a target nucleic acid that includes a nucleotide sequence encoding a motif of interest can be determined using a combinatorial ribozyme library. The members of the library are catalytic RNAs that disrupt the expression of the transcription product of the target nucleic acid. Disruption of transcription product expression results in an altered cell phenotype which is used to determine the function of the target nucleic acid. The specific phenotype or response may be associated with normal cellular processes, or it may contribute to the generation of pathogenesis involved in disease development. The compositions find use in high-throughput screens to assign gene functions. When associated with a pathogenic phenotype, these genes or their gene products can constitute therapeutic targets for treatment of diseases. The complete sequence of the gene containing the target nucleic acid need not to be known for the method to be used successfully.
