MEDIUM AND METHODS FOR THE STORAGE OF RED BLOOD CELLS
An aqueous storage solution for the storage of red blood cells, comprising an aqueous solution and at least one lipid, wherein the at least one lipid is effective in suppressing hemolysis in red blood cells and wherein the at least one lipid is emulsified within the aqueous solution.
Methods and Compositions for Preserving Tissues and Organs
The present invention generally relates to methods and compositions to determine viability of an organ for transplantation and other medical purposes. One aspect of the invention relates to a method for assessing the viability of an organ by measuring the energy parameters to determine the energy level of the organ by determining the stored cellular energy (e.g., ATP levels), and/or energy consumption over a particular time period of viability. The energy parameters can be compared to reference energy parameters as a highly accurate and reliable prediction of viable cell yield, and organ viability. Another aspect of the invention relates methods to preserve or extend the time period of viability of an organ any combination of (i) preservation perfusion of the organ to prevent ischemic damage, (ii) chemical metabolic suppression of the organ e.g., using metabolic suppressants, (iii) metabolic suppression by physical or environmental conditions, e.g., sub-zero non-freezing storage.

Methods and reagents for maintaining the viability of cancer cells in surgically removed tissue
A composition and method for generating reagents and the composition of these reagents for the stabilization and preservation of viability of cancer tissue which has been surgically excised and the suspension and/or termination of apoptosis (cell death) by significant modulation of cell metabolism by low molar concentrations of synergistic chemistries and hormonal growth enhancers while maintaining normal gene expression patterns of the surgically excised tissue.
METHODS FOR INHIBITING COMPLEMENT ACTIVATION AND USES THEREOF
The present invention provides methods for inhibiting complement activation and uses thereof. More specifically, the present invention provides methods for inhibiting complement activation using inorganic polyphosphates of at least 10 phosphate units. The polyphosphates inhibit complement activation by one or more of: binding to the C6 complement protein, C1-esterase inhibitor (C1-inh), factor H or factor B; enhancing the activity of C1-inh; interfering with C1s-mediated cleavage of C2; destabilizing the C5b-6 complement protein complex; interfering with C5b,6 interaction with C7; interfering with binding of C5b-7 to a cell membrane; interfering with integration of C5b-7 into a cell membrane; interfering with binding of C5b-8 to a cell membrane; interfering with integration of C5b-8 into a cell membrane; destabilizing the membrane attack complex (MAC); or reducing the amount of C5b-9 deposited on a cell surface.
MODULATION OF CALCIUM ION HOMEOSTASIS IN HARVESTED TRANSPLANTABLE HEARTS
An oxygenated cardioplegic composition for immediate reperfusion of a donor heart after its procurement. The composition comprises an adenosine-lidocaine mixture for causing immediate cessation of the heart's systolic function upon contact; a normokalemic concentration of potassium ions; a concentration of Ca.sup.2+ ions selected to maintain the intracellular level of Ca.sup.2+ ions in the harvested heart muscle cells at about 10.sup.4 mmol/L; and a pH of 6.9. The oxygenated cardioplegic composition is pre-warmed to about 35 C. and then used for immediate reperfusion of a donor heart for at least three minutes after its procurement.
System for hypothermic transport of samples
A system for the hypothermic transport of biological samples, such as tissues, organs, or body fluids. The system includes a self-purging preservation apparatus to suspend a sample in preservation fluid and perfuse a tissue with preservation fluid. The self-purging preservation apparatus is placed in an insulated transport container having a cooling medium. When assembled, the system allows for transport of biological samples for extended periods of time at a stable temperature.

System for washing red blood cells to reduce hemolysis
A system for washing red blood cells, comprising a separator configured to separate a quantity of blood into concentrated red blood cells having a hematocrit of at least 60% and a volume of 150-250 mL, and a supernatant component. The system comprises a flow controller configured to remove the supernatant component to provide an initial red blood cell concentrate; combine 50-500 mL of an additive solution with the red blood cell concentrate to provide an intermediate red blood cell product intended for storage for 42 days or less; and wash the intermediate red blood cell product with a washing solution.
