摘要:
Disclosed are tissue sealants that include whole blood and an effective amount of an exogenous protein cross-linker to cross-link the whole blood. Also disclosed are methods for forming a tissue sealant. Such methods include, providing whole blood and mixing the whole blood with an effective amount of an exogenous protein cross-linker to cross-link the whole blood into an adherent mass, thereby forming the tissue sealant. The disclosed tissue sealants can be used for any application, for example to achieve hemostasis, bond tissue of a subject and/or or seal a fluid or gas leak in a tissue of a subject.

An insertable stent is provided for joining together and facilitating healing of adjacent tissues. Typically, the tissues are mammalian tissues. The insertable stent is made from completely non-toxic, bio- and blood-compatible materials. Each of the tissues employed herein defines an internal cavity. The insertable stent body defines a bore. The bore permits fluid to pass through the insertable stent body. In use, the insertable stent body is introduced into the internal cavities of the tissues. The insertable stent body fits within the confines of, and in contact with, each of the adjacent tissues. Typically, at least a portion of the insertable stent body is fusible to the adjacent tissues for facilitating healing of these tissues.

An ultrasonic diagnostic imaging system for shear wave measurement transmits push pulses in the form of a sheet of energy. The sheet of energy produces a shear wavefront which is a plane wave, which does not suffer from the 1/R radial dissipation of push pulse force as does a conventional push pulse generated along a single push pulse vector. The sheet of energy can be planar, curved, or in some other two or three dimensional shape. A curved sheet of energy can produce a shear wave source which focuses into a thin line, which increases the resolution and sensitivity of the measuring techniques used to detect the shear wave effect.

Shear wave dispersion ultrasound vibrometry (SDUV) is implemented in some embodiments to form, from a single tracking pulse, in-parallel-directed receive lines (411-426) for making measurements of a monochromatic shear wave. In some embodiments, sampling is performed, over spatial locations by means of passes over the locations, in an interlaced pattern (600) for making measurements of the wave. In some embodiments, measurements are made of the wave and to the measurements are applied a bank of filters (S724) that are tuned to respective candidate wave speeds, all without the need to determine a difference between wave phases at different spatial locations (451-454).

A hollow core article of gluelam wood or engineered bamboo furniture, such as bench or table, includes a horizontal main panel (1) and a pair of vertical side panels (2) having upper ends respectively connected to opposite ends of the main panel (1) to support it. The main panel (1) includes a main framework (11), an upper plate (12) disposed on ledges (1115) on an upper surface of the mainframe work (11), and a lower plate (13) having edges disposed on ledges (1116) on a lower surface of the main framework (11). Each of the side panels (2) includes a side framework (21), an outer support plate (22) having edges disposed on ledges (2116) and (2115) on an outer surface of the side framework (21), and an inner support plate (23) having edges disposed on ledges (2116) and (2115) on an inner surface of the side framework (21).
摘要:
Glue-laminated bamboo furniture articles include a main panel (1) and plural panel supports (2). The panel (1) includes a main framework (11), a main plate (12) disposed on the main framework (11) and outer framework (13) covering the main framework (11). The main framework (11) is formed by joining corresponding ends of a plurality of frame borders (111). The main plate (12) corresponds in shape to a plane enclosed by the main framework (11) and includes slopes on interfacial edges (121) thereof. The outer framework (13) is formed by joining corresponding ends of sealing plates (131). Sloped upper ends (1311) of the sealing plates match the slopes on the interfacial edges (121) of the main plate (12). The resulting gluelam bamboo furniture has a trim aesthetic appearance, exhibits the beautiful natural texture of bamboo, effectively prevents the furniture from warping, has great durability, conserves materials and effectively reduces production costs.

摘要:
A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises a biomaterial suturelessly bonded to the valve frame, avoiding sutures and substantially reducing medical complications in implantations.

A Discrete Fourier Transform watermark for use with digital images/video. A Y component of a Y, U(Cb), V(Cr) digital data stream representing color components of digital video is extracted as the digital data for embedding the watermark. The digital data is then scaled to a standard size. A Discrete Fourier Transform (DFT) is performed on the digital data, and a magnitude domain of the Discrete Fourier Transform is computed. The watermark is embedded into selected frequency bands of the computed magnitude domain of the Discrete Fourier Transform, thereby creating a watermarked magnitude domain. The selected frequency bands comprise one or more middle frequency bands, and the middle frequency bands comprise a band of circular rings of the magnitude domain. An inverse Discrete Fourier Transform is performed on the watermarked magnitude domain to reconstruct the digital data with the embedded watermark.

A bioprosthetic valve graft comprises a valve frame and valve flaps, the latter acting to open or close a valve aperture to directionally control fluid flow through the bioprosthesis. The bioprosthetic valve graft comprises method for suturelessly attaching a biomaterial suturelessly bonded to the A method for securing a biomaterial to a valve frame includes positioning a flexible valve frame defining an open area on a first major surface of a biomaterial sheet having a peripheral edge, wherein positioning serves to approximate the valve frame and the peripheral edge of the biomaterial sheet to form an at least first bonding locus: and suturelessly bonding the biomaterial to the valve frame at the at least first bonding locus. The method avoids the disadvantages associated with conventional sutures and substantially reduces medical complications in implantations.
