  • Publication number: 20230241182
    Abstract: A product and method of using albumin nanoparticles for treating multiple traumas by augmenting the function or effectiveness of stem cells or precursor cells in vivo. An albumin nanoparticle suspension containing submicron albumin spheres is prepared, with the albumin spheres being capable of augmenting a function and effectiveness of stem cells or precursor cells in vivo for treating multiple traumas at the same time. A predetermined amount of the albumin nanoparticle suspension is administered to a patient before or after an onset of multiple traumas. A function of the stem or precursor cells can be augmented or improved by the albumin spheres to stimulate mobilization toward the traumas, to ameliorate an inflammatory response of the subject by decreasing an amount of RANTES endothelial production on cytokines production, and/or to improve a secretion of fractalkine. The albumin spheres can be bound with fibrinogen molecules in vitro or in vivo.

  • Publication number: 20210259972
    Abstract: A product, composition, suspension and/or method to treat subjects infected with respiratory viruses, such as coronavirus, and in relieving hypoxic condition. A suspension of thrombolytic albumin nanospheres that can target vaso-occlusive clots in vivo and then lyse the obstructive blood clots with high efficiency can be intravenously administer to a subject in need thereof. The nanospheres can encapsulate an enzymatically active bioreactive agent, such as urokinase. Since the active enzyme is targeting and binding essentially only to obstructive clots, there is minimal risk of side-effects to the subject. The nanospheres are less than one micron in diameter, resulting in a size much smaller than red blood cells.

  • Patent number: 9629931
    Abstract: The present invention is associated with a method of evaluating platelet function in vivo using skin-irradiation and nanoparticle radiation treatment. The present invention in the recovery of radiation skin injury suggests that radiation skin injury can be used as a substitute model to evaluate platelet substitute products instead of measuring bleeding times. Submicron nanoparticles and a future platelet treatment product are administered intravenously before and after irradiation to subjects. The resultant radiation skin injury are compared and used to evaluate the effectiveness of the platelet treatment product on platelet function in vivo. The radiation skin injury can serve as a model to evaluate platelet and platelet-substitute products, by replacing bleeding time measurements.

  • Patent number: 9504641
    Abstract: A method of treating a patient who has extravasation of blood from an intravascular compartment to an extravascular compartment. An agent is administered to the patient which mitigates a harmful effect of break-down products of blood at an extravascular site, resulting in the patient having reduced morbidity and mortality. The morbidity and mortality of the patient is further reduced by concomitant administration of a suspension of submicron protein spheres having a molecular weight of ranging from 780 billion Daltons to less than 0.8 billion Daltons.

  • Patent number: 9351925
    Abstract: A submicron protein sphere and method to intravenously treat a patient requiring blood component transfusion. The submicron protein spheres have a size ranging from 1.0 micron to less than 0.1 micron and a molecular weight ranging from 780 billion Daltons to less than 0.8 billion Daltons. The protein spheres have no biologically active molecules added or bound to the protein spheres prior to administering to the patient. The protein used to construct the spheres can be human serum albumin from natural sources or recombinant DNA-derived serum albumin, or other proteins such as gelatin or synthetic polypeptides. However, the protein spheres can bind the various clotting factors including fibrinogen after the spheres have entered the blood stream, binding the necessary additional biologically active molecules supplied in vivo from the patient's own blood, and possibly in vitro.

  • Publication number: 20160045573
    Abstract: The present invention relates to a method using fibrinogen-coated albumin spheres for treating a patient infected with a hemorrhagic virus. A suspension of protein nanoparticle containing submicron protein spheres is prepared and administered to the patient. The protein spheres are bound with fibrinogen molecules in vitro or in vivo. The fibrinogen-coated albumin spheres provide improved hemostatic function of a residual concentration of platelets of the patient resulting in decreasing mortality rate or decreasing morbidity of the patient. The fibrinogen-coated albumin spheres protect an endothelial function of an endothelial cell of a blood vessel of the patient resulting in improved permeability control across predetermined tissues in the patient, thereby counteracting an effect of the hemorrhagic virus on a wall of the blood vessel.

  • Patent number: 9114127
    Abstract: A microscopic protein device and the method of manufacture and the use of such a device for hemostasis. The device, made with biologic material such as serum albumin from a human or animal source, is less than five micron in any one dimension and typically less than one micron in diameter. It does not have any other biological or drug molecules attached to it in vitro. However, the device has properties that allow it to capture, concentrate, carry or bind biomodifying molecules, such as coagulation factor(s), or potentially other drugs, after exposure to plasma in vitro; and possibly in vivo as well. After infusion of said device intravenously inside the body, hemostatic effects can be demonstrated.
