Abstract: 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.

Abstract: The present invention relates to lipid removed scaffolds(lipid-free scaffolds) for human tissue volume replacement or cell culture. More particularly, the present invention relates to a method for preparing lipid removed scaffolds(lipid-free scaffolds) for human tissue volume replacement or cell culture, the method comprising the steps of: fragmenting fat tissue to isolate lipids by ultrasonic treatment or high pressure nozzle spray; removing the isolated lipids and fat tissue from which lipids were not isolated to sterilize. According to the present invention, lipids are removed from fat tissue only by physical treatment to maintain the volume thereof and microstructures such as cellular membrane as much as possible and thus the inventive scaffolds are useful for human tissue volume replacement.

Abstract: Various embodiments disclosed herein provide for reagents and methods for rapidly isolating viable microbial cells, including S. pneumoniae, from positive blood culture samples. The resulting microbial pellet can be used for both identification and growth-based methods such as antimicrobial susceptibility testing. The buffers described herein may contain a base solution, non-ionic detergents, thiols, and optionally, ammonium chloride. The disclosed methods provide a process for rapidly isolating and concentrating viable microorganism (s) from PBC samples using only one sample preparation tube and centrifugation while removing cellular debris from the mammalian blood cells that may interfere with identification methods.

Abstract: The invention is based on the use of photoluminescent probes for intracellular sensing of oxygen, especially assaying intracellular oxygen concentration. The photoluminescent probe comprises a suspension of polymeric particles having an average diameter in the 20 nm to 100 nm range, formed from an amphiphilic cationic co-polymer which is oriented in the formed particle to provide a hydrophobic core and a hydrophilic shell. The probe includes a hydrophobic oxygen-sensitive photoluminescent dye such as Pt-tetrakis(pentafluorophenyl)porphine, PtPFPP embedded in the hydrophobic core of the particle, and the co-polymer includes quaternary ammonium groups which provide hydrophilic and cationic character to the particle shell. The photoluminescent probe, which in use is provided in the form of an aqueous suspension of probe, is incubated with live mammalian cells in a suitable growth medium for a period of time to allow the probe particles passively load into the cells.

Abstract: A ratio of rare cells to non-rare cells in a blood sample suspected of containing rare cells and non-rare cells is enhanced. A treated blood sample is prepared by providing in combination the blood sample, a platelet deactivation agent, a fibrin-formation-arresting agent and fibrin in an amount sufficient to cause a predetermined level of agglutination of the rare cells. The treated blood sample is then contacted with a porous matrix such that agglutinated rare cells are preferentially retained on the porous matrix. The rare cells may then be identified.
