  • Patent number: 9051603
    Abstract: In invention relates to a method for the isolation of RNA from tissue pretreated with formaldehyde comprising homogenizing the sample in the presence of a guanidinium salt in aqueous solution, and incubating the sample in the presence of 0.1 M to 5 M ammonium salt at a temperature between 50° C. and 100° C. The heat treatment in the presence of an ammonium salts demodifies RNA by reverting methylol groups which are formed in the presence of formaldehyde between amino groups in nucleobases of RNA and in basic amino acids, and by cleavage of methylene bridges between amino groups in nucleobases of RNA and basic amino acids, to provide high RNA recoveries and consistently high quality of RNA for further reaction, e.g. for reverse transcriptase-polymerase chain reaction or microarray analysis.

  • Publication number: 20150141637
    Abstract: The present invention provides novel tricyclic nucleosides and oligomeric compounds prepared therefrom. Incorporation of one or more of the tricyclic nucleosides into an oligomeric compound is expected to enhance one or more properties of the oligomeric compound. Such oligomeric compounds can also be included in double stranded compositions. In certain embodiments, the oligomeric compounds provided herein are expected to hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.

    Abstract: A device for detachment and explantation of bone implants, in particular tooth implants, from their connection to the bone tissue comprises a unit having an elongated handle (10), a cooling module (7), a vibration module (8) for generating mechanical vibrations, and a grip head (6) which is secured to the handle (10) and which has a seat (14) for the bone implant to be explanted, in particular an implant head of the bone implant, or for an adapter piece for gripping the bone implant. The grip head (6) is coupled to the cooling module (7) and to the vibration module (8) in such a way that it is coolable to a desired temperature by means of the cooling module (7), and the vibrations of the vibration module (8) are transferable into the grip head and further to the bone implant or the adapter piece. The seat in the grip head (6) has at least one clamping element (12-15) which is able to exert radial clamping forces, with respect to a rotational axis, on the bone implant or adapter piece held in the seat (14).

  • Publication number: 20110184381
    Abstract: Methods and compositions are provided for the treatment and repair of defect in the cartilage in partial- or full-thickness defects in joints of animals, in particular humans. To induce cartilage formation, a defect in cartilage is filled with layers of thin flaps of synovium or of peritendineum, which contains chondro- and osteo-progenitor cells, with interposed layers of a matrix. The matrix contains a chondrogenic factor, which induces chondrogenesis of chondroprogenitor cells in the flaps, and an anti-hypertrophic agent, which arrest differentiation of chondrocytes in an early phase, in an appropriate delivery system. The matrix filling the bone area of a full-thickness defect may contain an osteogenic factor, which induces osteogenesis of osteoprogenitor cells. The layer of a flap between cartilage and bone areas may work as a barrier, which prevents blood vessels and associated cells from penetrating from the bone area into the cartilage area.

  • Patent number: 6754249
    Abstract: A method for generating polarized laser output radiation utilizes a laser resonator whose active medium exhibits thermally induced birefringence. The radiation fields oscillating in the laser resonator are not subjected to polarization selection, and only the radiation field exhibiting the desired polarization state (p) is partially output. Only a prescribed polarization of the radiation fields of the laser radiation which can oscillate in the resonator can be partially output from the resonator with a prescribed output level and all differently polarized radiation fields remain in the resonator in a completely reflecting fashion.
