Abstract: The present invention relates to methods for removing antiplatelet agents and anticoagulants from a platelet preparation. In one embodiment, the method includes the step of flowing the platelet preparation through a filtering tube comprising a filtering membrane and separating the antiplatelet agents and anticoagulants from the platelet preparation by tangential flow filtration. In another embodiment, the method includes the step of passing the platelet preparation through porous material that specifically binds to the antiplatelet agents and anticoagulants.

Abstract: A blood product (10), a method for preparing the blood product, a blood product obtainable by the method and a blood product preparing container means. The blood product comprises components from whole blood, especially fibrin, thrombocytes and leukocytes. The blood product (10) comprises a first layer (21), a second layer (22) and a third layer (23). The second layer (22) is adjacent to the first layer (21) and the third layer (23). The first layer (21) defines a first outer surface (24) of the blood product (10) and the third layer (23) defining a second outer surface (25) of the blood product (10). The first layer (21) comprises a majority of fibrin, the second layer (22) comprises a majority of thrombocytes and the third layer (23) comprises a majority of leukocytes.
Abstract: Blood storage and/or rejuvenating compositions that include D-ribose and an arginine (e.g. L-arginine, D-arginine, or a combination thereof) are disclosed herein. Such compositions can be useful in methods for treating (e.g., storing and/or rejuvenating) red blood cells.
Abstract: Methods and compositions for resuscitating, storing, and preserving functional integrity of organs and tissues. Metabolic function is maintained by sustaining ATP levels, mitochondrial function, cardiomyocyte contractility, prevention of acidosis, inhibition of induction of apoptosis, maintaining ionontrophy and lusiotrophy by regulating calcium, sodium, potassium and chloride ions.

Abstract: The present invention relates to compositions and methods for storing platelets to preserve the function and freshness of the platelets. More particularly, the present invention relates to the use of a preservative composition having an antiplatelet agent, an anticoagulant, and an oxygen carrier, for maintaining the freshness of platelets. Additionally, the composition may also contain an ultra-short acting broad spectrum anti-microbial agents. The preservative composition may be used to store platelets in a liquid state, a frozen state, or a freeze-dried state.
Abstract: Disclosed are compositions and methods for the preservation, storage, and transport of living biological tissues, organs, and populations of isolated cells. In particular, the disclosed compositions and processes permit mammalian cells, tissues, and organs to be harvested from suitable donor animals, stored for prolonged periods, and transported to the site of recipient implantation, all without significant loss of cell viability, biological activity, and/or tissue integrity.

Abstract: Provided herein are methods for detecting endotoxin or Gram negative bacteria in a sample. Kits for detecting endotoxin or Gram negative bacteria in a sample are provided.
Abstract: Described herein are compositions and methods particularly useful in the medical arts. The compositions and methods may be used in connection with the preservation of a portion of a mammal, for example, tissues, organs, appendages, limbs, extremities, stem cells, myocytes, bone marrow, skeletal muscle as well as an array of other medical procedures, such as cardiac surgery, transplantation and/or preservation. In various embodiments, the inventive composition may be hyperoxygenated and be formulated to resemble the biochemistries of natural intracellular fluids. The inventive composition includes active ingredients to reduce ischemic, hypothermic and reperfusion injury during transplantation, thereby resulting in improved post-transplant graft function and quality, when used in connection with organ transplantation and storage procedures, for example cardiac transplantation.

Abstract: A red blood cell storage composition includes a composition of red blood cells and biochemistry altering reagents, the biochemistry altering reagents being present at a concentration so as to reduce the percent hemolysis of the red blood cells during the freeze-thaw cycle below that of the percent hemolysis of the red blood cells in the absence the biochemistry altering reagents. The red blood cell storage composition preferably includes reagents selected from: modifiers of glycolytic/metabolic components, modifiers of antioxidant potential, effectors of intracellular ionic distribution, modifiers of membrane fluidity, modifiers of cytoskeletal structure, effectors of the cyclooxygenase second messenger pathway, effectors of the lipoxygenase second messenger pathway, effectors of the hexose monophosphate second messenger pathway, effectors of the phosphorylation second messenger pathway, modifiers of specific messenger molecules, and combinations thereof.

Abstract: A virally safe, thrombin-free factor-XIa concentrate or a coagulation factor concentrate which contains factor XIa as an active pharmaceutical ingredient and which is obtained by fractionation of plasma or serum or by genetic engineering and is suitable for the treatment of coagulation disorders attributable to diminished and/or delayed thrombin formation.
Abstract: Disclosed are methods for pathogen reduction in blood by illuminating with UV light while taking steps for preservation of blood components and reducing oxidative damage from reactive oxygen species generated during UV light exposure. Fresh whole donor blood or products derived therefrom may be submitted to UV light treatment while in a low oxygenation state defined by a partial oxygen pressure below a normal level. Such low oxygenation state occurs naturally shortly after blood collection or may be induced by exposure to low-oxygen environment, reducing temperature or by other disclosed steps.
Abstract: The invention relates to the use of at least one globin and/or at least one globin protomer and/or at least one naturally extracellular native hemoglobin for the preservation of organs, tissues, organ and tissue cells and cell cultures.
