    摘要: A cost-effective, scalable technique for producing microspheres loaded with biologically active solid proteins is provided. The microspheres degrade over time and release biologically active VEGF, as demonstrated by the proliferation of HUVECs in vitro compared to negative controls. A defined concentration of microspheres can deliver a quantifiable level of VEGF with known release kinetics. The invention can be used with other growth factors and applied to tissue engineering applications such as the regeneration of peripheral nerve, bone, adipose tissue, and solid organs. The method of the invention includes the steps of dissolving a polymer with an organic solvent to produce a polymer solution; adding a biologically effective amount of a bioactive substance to the solution to produce a mixture of the polymer and the bioactive substance; vibrating the mixture to produce a bioactive substance-polymer complex; emulsifying the mixture to produce an emulsion comprising the bioactive substance-polymer complex; and extracting the organic solvent from the emulsion to produce microspheres comprising the polymer-bioactive substance complex, wherein the bioactivity of the bioactive substance is usefully preserved.

    摘要: A system for indicating an area of interest on an image, including a source of image data, an image processing unit, a user interface, and a destination, which may be a display. The image data may be ultrasound, X-ray, magnetic resonance imaging, nuclear magnetic resonance imaging, magnetic resonance tomography, computed tomography or surgical image data. The image processing unit may be configured to receive the image data from the source and combine it with a desired overlay pattern selected from a plurality of overlay patterns for indicating an area of interest on the image, which is then displayed on the display. The overlay pattern may include a key with coordinates or labels. Properties of the overlay pattern and the image data may be adjusted independently or automatically.

    摘要: The aircraft applicable current imbalance detection and circuit interrupter interrupts an electrical circuit when a current imbalance is sensed. The current imbalance detection and circuit interrupter includes a housing, power supplies, a sensor system for sensing a current imbalance at the line side of the electrical circuit, a logic controller and a power controller including a power relay having contacts capable of surviving carry-break and make-carry-break types of ground fault conditions at anticipated current levels. At power up, the device performs a test to confirm that none of the relay contacts have failed in a closed position, and to check whether a switching FET which controls the relay coil has shorted.

    摘要: A double-wound center-feed roll is disclosed which is formed from at least two webs each having lines of weakness which allow the webs to be separated into a plurality of sheets. The lines of weakness of one web are offset from those of the other such that in use the sheets can be dispensed singly from alternate webs. A first portion of the webs at the center of the roll is lightly bonded together while a second portion of the webs on the outside of the roll remains unbonded. The center-feed roll of the present invention reduces the occurrence of both web orientation reversal and streaming dispensing problems.

    摘要: Still image display of a recent video image of tissue as a reference still image prior to a switch in the mode of illumination of the tissue. The still image is displayed concurrently with live video of the tissue under a different mode of illumination, to facilitate discrimination between healthy and diseased tissue. When a practitioner switches a light source from a “first light” to a “second light”, the second light video may be frozen/captured and displayed as a reference still image as a PIP, and the second light live video is displayed concurrently. The second light can be infrared and/or near infrared light. The second light can include structured light to project a structured light pattern to facilitate structure measurements. The second light source is configured with a numerical aperture greater than the first light source.
