Abstract: A securing system includes a fastener and a tape. The fastener includes a main body portion having a first end and a second end, a curved portion extending from the first end, first and second legs extending from the second end, and a roller extending between the first and second legs. The tape may extend around the roller and may be self-adhering.

Abstract: Embodiments related to a hold down brush with an improved tine configuration that can be used in a corrugator machine. The hold down brush can include multiple rows of tines made from acetyl, wherein the tines are embedded within a polyurethane base of the brush. The acetyl tines are food-grade and reduce or eliminate breakage. Embedding the tines (as opposed to gluing them) reduces or eliminates dislodging of the tines in operation. In addition, the hold down brush can be made into a number of small brush segments, which can facilitate quick and easy replacement and maintenance.

Abstract: A device is disclosed for taking critical measurements of a dental patient's anatomical features to aid in building prosthetic teeth in a minimal number of patient visits. The device to a multi-functional tool for dental professionals to acquire valuable anatomical data.

Abstract: A method for producing a customized, digitally-designed prosthesis in three (3) patient interactions, the method comprising a first patient interaction including the optional tasks of acquiring a patient's intra-oral anatomy, natural anatomical measurements of the patient, and tooth data of the patient, the results of the first patient interaction producing a first data set; Utilizing the first data set to design a first digital prosthesis, the first digital prosthesis being manufactured into a first denture base and obtaining artificial teeth; a second patient interaction including the optional tasks of seating the first denture base in the patient, adjusting the positioning of the artificial teeth to the first denture base, making an interocclusal record with the first denture base, the results of the second patient interaction creating a second data set utilizing the second data set to create a final digital denture, the final digital prosthesis being manufactured into a final dental prosthesis; a third in

Abstract: A universal impression tray can be reshaped shortened or lengthened allowing a clinician the ability to use one tray in any clinical situation. The tray itself can be used with patients requiring complete removable dentures, root supported and implant-supported overdentures and in some selected dentate cases. The tray can be infinitely modified allowing total control by the clinician. Trays in accordance with features of the present invention are made of a material composition including thermoplastic resin and thermochromic pigment. The material composition softens and changes color in warm water but tends to hold its shape until manipulated by the dentist. The thermoplastic resin portion of the tray can include polycaprolactone resin, styrene resin and dental modeling compound and can vary for specific uses to roughly 50% polycaprolactone /styrene resin and 50% dental modeling compound. Thermochromic pigment can represent up to 5% of the overall material composition of a tray.

Abstract: The present invention affords means for decontaminating biological fluids such as blood and blood components. The method involves contacting a biological fluid with a diphenylpyrilium compound, and irradiating the mixture with red light. The method is a potent and effective means for eliminating or diminishing active pathogens such as viruses, bacteria, and parasites, without causing substantial hemolysis or otherwise degrading the storage stability of the decontaminated biological fluid.

Abstract: Asymmetric cyanine dyes of Formula I bind nucleic acid but not red blood cell membrane, and function as photosensitizers when rigidly bound but not when free in solution. Unbound dye thus causes minimal oxidative damage. The dyes do not substantially accumulate in red blood cells, thereby minimizing hemolysis due to oxidative damage. Biological fluids can be disinfected by mixing the fluid with these asymmetric cyanine dye that binds to nucleic acid, irradiating the mixture, and recovering clinically significant components from the biological fluid and/or assaying the fluid for pathogens.

Abstract: The present invention provides methods and apparatus for the rapid and efficient collection and purification of activated monocytes. The methods and apparatus of the present invention provide means for effecting the collection and purification in an aseptic environment. The method involves filtering a blood component mixture through a monocyte-adhering filter; washing the blood component mixture; backflushing the filter with a physiological solution; and backflushing the filter with Dextran-40/serum albumin.

Abstract: Provided are chalcogenoxanthylium compounds which can effectively be used as sensitizers in photodynamic therapy, virucides in photodynamic antimicrobial chemotherapy and reversal agents of Pgp function in cancer cells. Further provided is a general method for the preparation of chalcogenoxanthylium compounds.
