Abstract:
The invention relates to an artificial bone implant for preservation, repair, and regeneration of the human musculoskeletal apparatus by means of orthopedic, dental and craniofacial implantation. More in particular, the invention relates to use of osteoinductive compositions comprising stem cells from adipose tissue and osteoconductive calcium phosphates in bioresorbable cages as part of an artificial bone implant for stabilization and renewed alignment of spinal column segments.
Abstract:
A nano-scale manipulator (10) comprises a mounting deck (11) and a frame (12), the deck (11) being moveably secured to the frame (12) by two flexural joints permitting movement of the deck relative to the frame in first and second respective, mutually orthogonal directions of movement. Manipulator (10) also includes at least one respective, elongate piezoelectric actuator (21, 22) for each of the flexural joints, each respective piezoelectric actuator (21, 22) being secured so as to interconnect the deck (11) and the frame (12) and being extensible and contractible in a direction that is parallel to one of the said directions of movement; and a source (23) of electrical power for causing operation of each piezoelectric actuator (21, 22). Each of the piezoelectric actuators (21, 22) also is free to flex in directions other than its direction of extension and contraction.
Abstract:
The invention provides a luminescent optical device (10) having an optical waveguide (200). The luminescent optical device (10) further has a photo-luminescent structure (100) on or inside the optical waveguide (200). The photo-luminescent structure (100) comprises a plurality of photo-luminescent domains (110) containing photo-luminescent material (120). The photo- luminescent material (120) is capable of emitting emission light upon excitation by excitation light. The photo-luminescent domains (110) are arranged to emit, upon excitation by excitation light, at least part of the emission light into the optical waveguide layer (200). The luminescent optical device (10) further may comprise a lens structure (300) on the optical waveguide (200). The lens structure (300) comprises a plurality of lenses (310), arranged to capture incident light provided from an external light source, in particular the sun, and to concentrate the incident light onto the plurality of photo-luminescent domains (110) as excitation light for excitation of the photo-luminescent material (120).

Abstract:
The present invention relates to a : for producing a genetically modified plant that has early flower meristem development as compared to a corresponding unmodified or wild type plant. The method comprises transforming a plant with a nucleic acid construct that comprises a nucleic acid sequence encoding a DOT ortholog (DOT is the Petunia ortholog of UFO) operably linked to a promoter, such that the DOT ortholog is ectopically expressed. The method is preferably applied to plants with early expression of an ALF ortholog (ALF is the Petunia ortholog of LFY) in the vegetative apical meristem. Such preferred plants are e.g. plants that belong to the Solanaceae . The invention further relates to genetically modified plants having early flower meristem development as a result of ectopic expression of a DOT ortholog, to products obtained from such plants, as well as to nucleic acids encoding a DOT ortholog.
Abstract:
A device for moving a first object relative to a second object, which device comprises a first part, which can be fixed to the first object, and a second part, which can be fixed to the second object. The first part comprises an elongated portion, along which the second part can move, which second part is provided with a clamping member, which is capable of clampingly engaging the elongated portion. The clamping member comprises shape memory metal, which gives the clamping member a clamping shape or a releasing (non-clamping) shape, depending on the temperature of the shape memory metal. The device may be suitable for being implanted into a human or animal body, whereby the first object is a first bone portion and the second object is a second bone portion, which bone portions are to be moved relative to each other.
Abstract:
A system for extracting flow information from a dynamic volumetric angiography dataset is configured for segmenting (202) a vasculature structure by labeling certain voxels of the dynamic volumetric angiography dataset as belonging to the vasculature. For each of a plurality of the labeled voxels, (203) a voxel time value is calculated indicative of a time when a time sequence of a voxel of the dynamic volumetric angiography dataset satisfies a certain predetermined condition. A histogram is calculated (204) of the calculated voxel time values. The system determines (205) a time window having a lower voxel time value and an upper voxel time value, by fitting a model to the histogram, wherein the model defines the time window in terms of certain predetermined features of the histogram. The system associates (206) a first color to the lower voxel time value, and a second color to the upper voxel time value.
