Abstract: Embodiments of the invention are directed to methods of treating a wound by administering a wound-healing composition and the wound-healing composition. The wound-healing composition has a purified platelet-removed platelet-rich plasma and a wound-healing component. The wound-healing component is a protein, a peptide, or combinations thereof. The methods of treatment utilize an amount of the wound-healing composition sufficient to treat a patient with a wound, which may occur by promoting an activity of cell migration, cell proliferation, and/or angiogenesis. Also disclosed are processes for preparing the wound-healing composition.

Abstract: A sub-atmospheric, negative pressure is applied to a growth factor starting material, such as whole blood, to release growth factors and plasma in a non-destructive medium. The released growth factors having a weight of about 70-76 kDaltons are applied in either a filtered or unfiltered state to a wound to promote healing of the wound. The released growth factors are applied topically to the area of a surface wound to effect healing. The released growth factors are also injected into soft tissue, such as a torn tendon, to promote tissue growth and healing. The growth factors are released in one method from a patient's own blood. In another method the growth factors are released from a whole blood source and freeze dried by conventional lyophilization. Then at a later date, the freeze dried product is reconstituted by normal saline for treatment of a patient's wound or for use in a surgical procedure.

Abstract: The present invention provides a process for obtaining growth factors by treating a growth factor starting material to release growth factors from the growth factor starting material and recovering growth factors from the treated growth factor starting material. The growth factor obtained can be used in compositions to treat humans.

Abstract: This invention relates to an improved Lyophilized platelet rich plasma used to make a platelet gel wound healant, and methods of preparation and use thereof for healing wounds are disclosed. The improved wound healant comprises therapeutically effective amounts of activated growth factors, platelet ghost, plasma (know as the plasma back bone), white blood cells with optional none, one or more additional anti-oxidant such as vitamin A and/or C and/or E, and/or none one or more antibiotics and/or GHK-Cu (produced by ProCyte Inc.

Abstract: A wound healing composition derived from a low platelet concentration plasma preparation is described. The composition differs from conventional platelet gel preparations in that the centrifugal conditions under which the low platelet concentration plasma is prepared are less stringent than those for the preparation of platelet rich plasma and platelet concentrates. As a result the low platelet concentration plasma preparation from which the wound healing composition of the present invention is prepared has, as its name implies, a concentration of platelets that is lower than the platelet concentration of platelet rich plasma or of whole blood. Methods of making and using the wound healing composition of the present invention are also described.

Abstract: A printing system includes a scanner, a graphics computer, and a printer. The scanner optically scans an image and reduces it to a series of pixels represented in gray scale. After the scanner finishes converting the image into pixels, the graphics computer converts the gray scale representations of each pixel into a pixel conveying uniform density color information. The graphics computer then outputs the uniform density pixels to a print control system of the printer. The print control system receives the uniform density pixels and controls a printhead to print a reproduction of the image on a substrate suspended within the printer. Alternatively, the print control system controls a pair of printheads positioned on opposite sides of the substrate suspended within the printer to print a reproduction of the image on one side of the substrate and a mirror of the image on the opposite side of the substrate such that the images are in registry.

Abstract: A substrate guide and tensioning apparatus utilized with a printing system ensures the substrate does not flex or curl during printing to eliminate color mismatch among printed pixels. The printing system includes a scanner, a graphics computer, and a printer. The scanner optically scans an image and reduces it to a series of pixels represented in gray scale. After the scanner finishes converting the image into pixels, the graphics computer converts the gray scale representations of each pixel into a pixel conveying uniform density color information. The graphics computer then outputs the uniform density pixels to a print control system of the printer. The print control system receives the uniform density pixels and controls a printhead to print a reproduction of the image on a substrate suspended within the printer.

Abstract: The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image are converted by a color correction computer into control signals representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles located on a pair of printheads. Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first source is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations.

Abstract: A frame member for a sign assembly for use with flexible signs comprises an elongated body having an outer side having a front edge which defines a lip for engaging a back side of an edge portion of the sign and applying a tensile force to the sign. The channel extends longitudinally of the body and inwardly of the outer side thereof and opens in the outer side for receiving in edgewise fashion an elongated tensioning bar having an edge portion of the sign folded thereover and secured thereto by a plurality of spring clips. The channel is formed with a plurality of transversely spaced, inwardly facing shoulders which are engageable with the spring clips for securing the edge portion of the sign within the channel and enabling the sign to be tensioned by urging the tensioning bar inwardly of the channel to enable the material clamping means to successively engage successive shoulders.

Abstract: A sign assembly has a frame surrounding an aperture, and a sheet of flexible sign material has a main portion stretched across the aperture and an end portion secured to the frame. The frame has a lip member defining the aperture, the lip member having a free end over which the flexible sign sheet passes, the frame also having a U-shaped channel portion rearwardly of the lip member and receiving an end portion of the sign sheet. A mounting bar extends longitudinally within the U-shaped channel, and the sheet end portion is wrapped, around the mounting bar. A series of spaced U-shaped resilient clips retain the mounting bar and wrapped around sheet end portion therein. The U-shaped channel has at least one wall with a plurality of longitudinally-extending shoulders which face in a rearward direction from the lip member.
