  • Patent number: 5882864
    Abstract: Disclosed are diagnostic techniques for the detection of human prostate cancer. Genetic probes and methods useful in monitoring the progression and diagnosis of prostate cancer are described. The invention relates particularly to probes and methods for evaluating the presence of RNA species that are differentially expressed in prostate cancer compared to normal human prostate or benign prostatic hyperplasia.

  • Patent number: 5868746
    Abstract: A biocompatible osteosynthesis plate operable for being enhanced in a substantially secured relation to a plurality of adjacent bone portions is provided. The biocompatible osteosynthesis plate includes an elongated section having a top face and a bottom face, at least one fastener opening disposed between the top face and the bottom face, and means disposed upon elongated section to permit the formation of additional fastener openings therethrough during a surgical procedure. The osteosynthesis plate is in a first configuration at a first thermochemical state and is operable to be converted to a second thermochemical state so that it may be deformed prior to fixation. The osteosynthesis plate may further include means disposed upon the elongated section for enhancing structural rigidity, which may be provided as one or more raised surfaces, or rails, disposed upon the top face of the osteosynthesis plate.

  • Patent number: 4109051
    Abstract: A composition for coating glass fibers intended for use as reinforcement in cementitious products, containing, as a protective material, at least one monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring or (in a polycyclic compound) on at least one of the aromatic rings, said composition, when applied to a strand of glass fibres which is subsequently encased in a block of ordinary Portland cement paste which is allowed to cure and kept for 28 days at 50.degree. C, producing an improvement of at least 10% in the tensile strength of the strand as compared with that of a strand similarly treated and tested but without application of said composition. Preferably, the aromatic compound is soluble in a calcium hydroxide solution. A preferred compound is pyrogallol.

  • Patent number: 3954490
    Abstract: A cementitious product and production method wherein the product comprises cement with reinforcing glass fibres therein which are coated with a composition which consists essentially of a protective material to reduce deterioration of the glass fibres, the material being a monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring, or when a polycyclic compound is employed, on at least one of the aromatic rings. Preferably, the aromatic compound is soluble in a calcium hydroxide solution, and a preferred such compound is pyrogallol. The composition can also contain a film-forming agent such as a polyvinyl acetate of cationic character or a polyethylene glycol of non-ionic character, as well as a linking agent such as a silane.
