Patent SE-8803876-A (SE)
IPC: H03B1/04
Filed: 1988-10-28
Abstract: A device for preventing a crystal oscillator 11,12 being prevented from oscillating in the event of a harmonic frequency in the crystal 11 in the oscillator. The device comprises a feedback circuit and at least one frequency divider 14a, 14b, . which divides the frequency of the oscillator's output signal by an odd whole number, preferably three and five, etc. A signal which has the same frequency as the signal(s) formed by means of the frequency division is returned to the crystal as an interference voltage. If the oscillator starts to oscillate on any of the harmonics which correspond to the abovementioned whole numbers, for example third or fifth harmonics, it is caused by the returned signal to change over to oscillating at the basic tone frequency, as the returned signal contains this frequency. <IMAGE>

Title: G-rich oligo aptamers and methods of modulating an immune response
Inventor: TAM ROBERT
IPC: C12Q1/00
Filed: 1997-12-19
Abstract: Aptamer oligonucleotides specifically bind to the DNA binding site of proteins such as Sp1 and Sp1-related proteins which regulate the genes which encode costimulatory molecules such as CD28 and cytokines such as IL-2 and GMCSF. The oligonucleotides compete with the DNA-binding sites of regulatory proteins which specifically regulate molecules to modulate T-cell activation. This serves to modulate gene expression by preventing transcription of the gene. Aptamers are administered to provide therapies for diseases which involve aberrant T-cell activation such as psoriasis, Type I (insulin-dependent) diabetes mellitus, multiple sclerosis, autoimmune uveitis, rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease (Crohn's and ulcerative colitis), and septic shock and to regulate normal T-cell activation such as in allograft rejection
