  • Patent number: 5786391
    Abstract: For the first time, certain retinoids with a side chain terminal CH.sub.2 OH group or ester or ether thereof or aldehyde rather than a side chain terminal COOH group and substitution at the 4-position have been indicated to bind to nuclear receptors and to be biologically active in inducing cell differentiation of normal and tumor cells. These compounds activate gene expression through binding to nuclear receptor proteins. These compounds induce differentiation in normal and cancer cells and are useful for treating leukemias, and lymphomas, squamous cell carcinomas, deep (cystic) acne, psoriasis and photodamaged or aging skin. These compounds have stability and in vitro half-life advantages over and solubility differences from all-trans-retinoic acid and activity advantages over 13-cis retinoic acid.

  • Patent number: 4937568
    Abstract: A remote control system comprises a central control station and at least one local station installed remotely from the central control station and connected thereto through a power transmission line. The local station has a plurality to devices connected in parallel to one another at the output. The power for actuating the devices is supplied from the central control station. For controlling actuation of the devices, binary control signals are serially sent from the central control station to the local station through the power transmission line in synchronism with clock pulses in a train including a start pulse. In the local station, the binary control signal are extracted in response to the start signal and converted into parallel control signals by utilizing the clock pulses to be applied to output circuits provided for controlling the devices.
