Latest Patents

Yana Filkina's most recent patents include a groundbreaking **Method for Living Tissue Preservation**. This invention outlines a technique for platelet preservation that involves placing a platelet composition in a gas mixture containing xenon and oxygen under pressures of about 0-10 Bars at temperatures ranging from approximately 18°C to 37°C for an initial period. Following this, the composition is cooled to a second temperature between 0.1°C and 6°C while being maintained under pressure for an additional time.

Her second patent, titled **Method for Preserving Cells and Cell Cultures**, introduces a process aimed at reducing apoptosis in nucleated cells. This method involves holding nucleated cells in a container, adding a xenon-containing gas to maintain pressures between 0.5 to 4.0 Atm above ambient, while the temperature stays between 22°C and 37°C for a defined period. Subsequently, the temperature is lowered to between 0.1°C and 10°C while preserving the pressure, and finally, the pressure is reduced to ambient, raising the temperature back to 22°C to 37°C. This systematic approach effectively decreases cell apoptosis compared to references.
