153 results about "Cadaver" patented technology

A cadaver is a dead human body that is used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and artists.

PLGA/Hydroxyapatite Composite Biomaterial and Method of Making the Same

InactiveUS20090048358A1Fastly and highly and uniformly coatedGood at propagatingCosmetic preparationsImpression capsDiseaseApatite
Tissue engineering is a growing field where new materials are being developed for implantation into the body. One important area involves bone graft materials to replace areas of bone lost to trauma or disease. Traditionally, graft material may be harvested from the bone of the individual receiving the graft material. However, this requires an additional surgery and additional recovery. Bone also may be taken from others, or even cadavers, but this introduces biocompatibility problems as well as the risk of disease transfer. Ideally, a biocompatible material is sought that will act as a filler with appropriate mechanical strength, encourage bone healing, and degrade to allow new bone ingrowth without the risk of disease transfer. The present invention is a new composite bone graft material made from biocompatible poly(D,L-lactic-co-glycolic acid) (PLGA) and nano-sized hydroxyapatite particles exposed on its surface using a gas foaming particle leaching (GF / PL) method. A further embodiment of this invention involves coating this PLGA / hydroxyapatite biomaterial with an adherent, fast, uniform coating of a mineral such as apatite. The PLGA polymer portion of the composite provides sufficient mechanical strength to replace bone and is degradable over time to allow new bone tissue ingrowth. The incorporated hydroxyapatite particles increase the composite material's osteogenic properties by providing sites for tissue attachment and propagation. Finally, a uniform coating of mineral apatite on the surface of this novel biomaterial composite further enhances its osteogenic qualities.

Tissue engineered skin with basilar membrane and construction method thereof

The invention relates to the technical fields of tissue engineering and medical wound repair. At present, a living skin substitute constructed by using the materials of polylactic acid, polyglycolic acid, collagen, hyaluronic acid, and the like as a dermic bracket has the defects that on one hand, host materials are difficult to extract, the living skin substitute has complicated manufacturing technology and is expensive in cost and difficult to widely popularize and apply clinically; and on the other hand, the living skin substitute does not have a skin basilar membrane structure so that healed skin does not resist pressure and wear, and the living skin has unfirm adhesion to the epidermis and is easy to shed and break or form water blisters so that the structural and morphological development of the normal epidermis is influenced; and allogeneic acellular dermis is taken from cadaver skin and is limited in sources and expensive in cost, and thus clinical application is limited. The invention aims at providing a skin substitute which uses surface-finished and modified amnion as the basilar membrane and blood plasma as stroma, which has the advantages of wide material sources, low cost and simple preparation method. An animal experiment proves that the complete basilar membrane and hemidesmosomes can be retained in in-vivo transplantation, and the formation of an epidermal structural form is accelerated and promoted.

Harmless microorganism treatment method for cadavers of livestock and poultry

The invention discloses a harmless microorganism treatment method for cadavers of livestock and poultry. The method particularly includes the following steps: placing the cadavers in boxes, cutting, separating, crushing and slicing the cadavers, deoiling the sliced meat, fermenting and degrading the deoiled meat, performing high temperature sterilization and preparing a fertilizer, wherein during the fermenting and degrading step, thermophilus spoilage bacterium and mesophilic non-spore bacteria are employed as bacterial strains, wherein the thermophilus spoilage bacterium is composed of one or more selected from bacillus stearothermophilus, Cl.thermosaccharolyticum, clostridium butyricum, streptococcus thermophilus and bacillus macerans; and the mesophilic non-spore bacteria is composed of one or more selected from streptococcus liquefaciens, streptococcus faecalis, byssochlamys fulva, leuconostoc dextranicum, yeast and mildews. The organic fertilizer, by means of the key functions of the microorganisms, can supply various nutrient elements to crops and also can supply large amount of biotins, amino acids, vitamins, growth hormone, antibiotics and the like physiological active components that are necessary in growth of the crops.

Traceability process and security elements used in said process

Bi-directional cattle traceability process comprising five basic stages: a first document traceability and sanitary certification chain stage, wherein the animals are identified by birth certificates, animal identification attached to the animal's ear and registered in a data centre. A second stage for transfer of animals to another establishment, wherein genetic material is extracted from the offspring not yet weaned, filed and registered and registered in the data centre. A third stage for slaughtering of animals, wherein the slaughtered animal's ear is cut off where the animal identification is attached and the animal identification is read on line, the half carcases have sealed strips applied to them, DNA samples are extracted from the animal, then deposited in the official genetic bank and on each cut a locket sampler is attached encrypting a genetic and biochemical sample. A fourth stage for transfer or exporting of cuts, wherein the barcode that originated the cut is identified and applied to each portion of this cut or piece into which it is divided and then the locket sampler is removed from each sliced or minced cut, to deposit it in the cold storage chamber. A fifth and last stage of traceability auditing, wherein three samples of the identified portion of a cut to de audited are taken and adulteration of the cut or non-adulteration is determined by comparing the genetic sample taken in the third stage with the encrypted genetic sample in the locket sampler that held the original cutting extracted in the fourth stage.
Alternative traceability processes addressed to fishing and canning and a set of elements used in the different stages of the three processes are also disclosed.
