The invention refers to a composition for the fixation of histological preparations, comprising a solution of glyoxal, wherefrom acids, normally present in the commercially available glyoxal, have been removed. The composition of the invention provides an optimal fixative for the preservation of structure, antigenic components and nucleic acids in tissues. The acid-free glyoxal has limited toxicity, is not considered as a carcinogenic agent and represents a valid alternative to formalin for the fixation of tissues and cells.

The present invention is directed to compounds, methods for stabilizing thrombin activity with a thrombin binding oligonucleotide and to stabilized thrombin. The thrombin binding oligonucleotide is capable of inhibiting thrombin activity whereby the inhibition can be reversed with an antisense oligonucleotide.

A system for reconstituting circulation in a cadaver includes at least a pump, a fluid driven by the pump, and operative fluid connections between the pump and the cadaver. The system may be used to occlude one or more arterioles within the cadaver. The system may include a first circuit that creates a first fluid path with vessels of the cadaver, with first circuit having a first fluid conduit, a heater unit, a first pump, and a resistance device. The system may also include a second circuit that creates a second fluid path with vessels of the cadaver that are different from the vessels of the first circuit, with the second circuit having a second fluid conduit and a second pump. Alternately, the system may include a first circuit that creates a first fluid path with vessels of the cadaver and a second flow path that creates a second fluid path with the reservoir, where the first circuit includes a first conduit, a second connector, a pump, a reservoir, and a connector.

The present invention provides a mixture that serves for the preservation of Coleoptera to preserve its exoskeleton and its ornamental appearance; reinforce the exoskeleton of the coleopterous to minimize their fragility; improve the preservation of the insect by making an internal preparation that prevents rupture of the exoskeleton caused by blows, manipulation or pressure on it.

A solution for preserving extracellular vesicles/exosomes has a carrier solvent selected from a group consisting of polysorbate 80, sucrose, and polyethylene glycol 3350/4000; and a stabilizer selected from a group consisting of salts, amino acids, and amino acid salts; wherein the pH of the preservation solution ranges from 5 to 7.4.

The present disclosure relates to, at least, a vacuum-assisted method for infiltrating cadaver bone with a cryoprotectant and a method for rapidly warming the cryopreserved cadaver bone for bone marrow processing.
