The preservation or extension of the life of oxygen perishable products such as fresh or cooked meats; fresh vegetables and fruits; dried vegetables, fruits and meats; packaged pharmaceuticals or biologicals; open and enclosed marketing display cases of meats, fruits and vegetables; and packaging, warehousing and transportation of meats, fruits, and vegetables is obtained by subjecting such products to an atmosphere obtained from gas permeable packets of an oxygen scavenging composition comprising a sodium carbonate mineral and one or more carboxylic acids. When the environment surrounding the oxygen perishable product is subjected to the packets of gaseous permeable oxygen scavenging compositions, oxygen is taken in by the scavenging composition and also the presence of carbon dioxide in the surrounding environment is enhanced thereby minimizing or eliminating the effect the oxygen on the oxygen perishable products.

The present invention relates to a product and method for cell preservation, such as cell banking of any type of cells for subsequent scientific or medical use. More closely, the invention relates to a product and a method for cryopreservation of cells using vacuum tubes provided with freeze media/cryopreservation liquid.

A profusion system for a mammalian organ comprising a first and a second pump to propel perfusion fluid through one of a closed fluid circuit system and a selectively closeable fluid circuit system that includes an organ artery and an organ vein, a filter cartridge bank consisting of a plurality of filtration cartridges, and a first and a second fluid reservoir.

The present disclosure provides methods to improve the viability of an organ, or organs, by continuously administering a composition comprising NO.sub.x gas directly to the organ(s).

The present invention provides an acellular collagenous tissue and a method for processing an artificial heart valve containing the acellular collagenous tissue. The method comprises immersing the acellular collagenous tissue in a preservation liquid containing an ionic liquid until the size of the acellular collagenous tissue remains stable in a non-liquid environment. The present invention also provides a preservation method, comprising immersing the acellular collagenous tissue or the artificial heart valve containing acellular collagenous tissue in the preservation liquid containing ionic liquid until the size of the collagen tissue remains stable in the non-liquid environment. The present invention also provides an acellular collagenous tissue and an artificial heart valve containing the acellular collagenous tissue processed by the method described above. The method can effectively avoid a biological material damage caused by being in a non-liquid environment and is beneficial to implement a subsequent processing and sterilization for the biological material.

A method is disclosed for recovering living cells highly efficiently from cryopreserved cells by thawing and a system designed for such a method. The method for recovering living cells from cryopreserved cells includes thawing cryopreserved cells and diluting the thawed cell suspension with a diluent, wherein the dilution is performed in such a way that the maximum load of osmotic pressure at the time of dilution is equal to or less than 250 mOsm/second.

An apparatus for applying liquid pressure to resected tissue may include a fixture, a papillary assembly coupled to the fixture and having first and second spaced apart papillary attachment elements, and a resected mitral valve attached to the fixture. The fixture may have a first chamber, a second chamber, and an internal panel extending between the first and second chambers. The resected mitral valve may be attached to the internal panel and may have a posterior leaflet, an anterior leaflet, and tendinae chordae. The tendinae chordae may each be attached at a first end to the posterior leaflet or the anterior leaflet and at a second end to one of the papillary attachment elements. A first group of the tendinae chordae may be attached to the first papillary attachment element, and a second group of the tendinae chordae may be attached to the second papillary attachment element.

Embodiments of the present invention relate to compositions and methods for treatment of subjects in need of or having a bone marrow transplant. Certain embodiments describe compositions and methods for treatment of conditions associated with bone marrow transplantations in a subject, for example, Graft versus Host Disease (GvHD) or bone marrow transplantation rejection. Some embodiments concern early or immediate bone marrow transplantation rejection. Certain embodiments relate to compositions and uses of alpha1-antitrypsin (1-antitrypsin, AAT) and carboxyterminal peptide derivatives thereof and/or compositions and uses of serine protease inhibitors, immunomodulators or anti-inflammatory agent activity similar to that of AAT.

A container system and method for cryopreservation of sperm includes first containers having walls of a desired thickness and thermal conductivity. At least one layer of thermally insulating walls of a desired thickness and thermal conductivity is disposed around the at least one row of first containers. The first containers and thermally insulating walls are capable of being immersed from a range of about 5 C. to room temperature directly into a liquid cryogenic fluid below a surface thereof and freezing the sperm, without vitrification, at a cooling rate sufficient to maintain post-thaw quality of the sperm. The cooling rate is controlled solely by the thermal conductivity of the walls of the first containers, the layer(s) of thermally insulating walls and any substance between the walls of the first containers and the at least one thermally insulating container.
