Abstract: Methods are disclosed for producing defective ribosomal products (DRiPs) in blebs (DRibbles) by contacting cells with a proteasome inhibitor, and in some examples also an autophagy inducer, thereby producing treated cells. DRibbles can be used to load antigen presenting cells (APCs), thereby allowing the APCs to present the DRiPs and antigenic fragments thereof. Immunogenic compositions that include treated cells, isolated DRibbles, or DRibble-loaded APCs are also disclosed. Methods are also provided for using treated cells, isolated DRibbles, or DRibble-loaded APCs to stimulate an immune response, for example in a subject. For example, DRibbles obtained from a tumor cell can be used to stimulate an immune response against the same type of tumor cells in the subject. In another example, DRibbles obtained from a pathogen-infected cell or cell engineered to express one or more antigens of a pathogen can be used to stimulate an immune response against the pathogen in the subject.

Abstract: A chitosan biomaterial is frozen in aqueous solution to form a frozen chitosan structure from which water is removed by a prescribed freeze-drying process to form a sponge-like chitosan structure having a thickness and a density. The sponge-like chitosan structure is compressed by application of heat and pressure to reduce the thickness and increase the density of the sponge-like chitosan structure to form a densified chitosan structure. The densified chitosan structure is further preconditioned by heating the densified chitosan structure according to prescribed conditions to form a wound dressing. The wound dressing possesses an adhesion strength and resistance to dissolution in high blood flow bleeding situations.

Abstract: A process and/or system that extracts selected information from e.g. traditional electronics medical records to enable analysis of a determined medical condition shared by multiple patients. A data warehouse receives the extracted information and reformats that information to enable rapid analysis by a health care provider of that provider's patient population having that medical condition. It further collects the selective data of the selected patients for multiple health care providers and enables comparisons of health care providers' success for such patients to promote upgrading of the treatment by less successful providers.

Abstract: This invention is directed to advanced hemorrhage control wound dressings, and methods of using a producing same. The subject wound dressing is constructed from a non-mammalian material for control of severe bleeding. The wound dressing is formed of a biomaterial comprising chitosan for controlling severe bleeding. The kind of severe, life-threatening bleeding contemplated by this invention is typically of the type not capable of being stanched when a conventional gauze wound dressing is applied with conventional pressure to the subject wound. The wound dressing being capable of substantially stanching the flow of the severe life-threatening bleeding from the wound by adhering to the wound site, to seal the wound, to accelerate blood clot formation at the wound site, to reinforce clot information at the wound site and prevent bleed out from the wound site, and to substantially prohibit the flow of blood out of the wound site.

Abstract: Methods for measuring strains in biological and other samples include illuminating a specimen with substantially collimated laser flux. An electro-acoustic transducer is activated to generate acoustic waves in the specimen, including a surface wave component such as a Rayleigh wave. A series of laser speckle patterns produced by a laser flux scattered or reflected by the specimen is recorded and speckle pattern shifts are calculated based on the recorded speckle patterns. Phase shifts produced by acoustic wave propagation in the specimen are used to identify specimen regions associated with irregularities such as inclusions, cracks, or tissue abnormalities. In some examples, specimens are stretched or otherwise stressed by one or more light fluxes, and specimen elongation is estimated based on a series of associated speckle patterns.

Abstract: Methods for measuring strains in circuit substrates such as circuit boards and semiconductor wafers include illuminating a specimen with a substantially collimated laser flux. A temperature change is produced in the specimen and a series of laser speckle patterns produced by a laser flux scattered or reflected by the specimen is recorded. Localized strains are detected based on speckle pattern shifts that are calculated using the recorded speckle patterns. Stains can be recorded as a function of temperature or rate of change of temperature, and strains at one or more circuit substrate locations can be detected.

Abstract: One method for purifying a chitosan starting material includes contacting it with at least one treatment agent selected from a protein-complexing agent, a metal-chelating agent, and a metal-complexing agent under pH conditions effective for forming a water insoluble chitosan precipitate and at least one water soluble material selected from a water soluble protein complex, a water soluble metal chelate, and a water soluble metal complex. Another variant involves solubilizing the chitosan starting material in an aqueous solution to produce an intermediate chitosan material. The intermediate chitosan material is contacted with a deproteinization agent and/or a demetallization agent under pH conditions effective for forming a water insoluble chitosan precipitate and at least one water soluble material that includes the pre-existing impurity. In both methods, the water insoluble chitosan precipitate and the water soluble material are separated resulting in a purified chitosan material.

Abstract: The present invention provides a denatured albumin lamina, useful for repairing lesions on solid visceral organs. The lamina comprises human serum albumin, formed into a thin, pliant sheet and denatured. The denatured lamina can be sterilized and stored until used. As well, it can be impregnated with a variety of bioagents. A method for repairing a lesion on a solid visceral organ includes applying an energy-absorbing proteinaceous material to a lesion site on the solid visceral organ lesion; irradiating the proteinaceous material with energy sufficient to fuse the energy-absorbing material at least partially to the lesion site; applying a biocompatible denatured albumin lamina onto the proteinaceous material on the lesion site; and irradiating the biocompatible albumin lamina and the proteinaceous material with energy sufficient to fuse the biocompatible albumin lamina to the proteinaceous material and/or the lesion site.
