Title: Innovations in Blood Platelet Preservation by George Dayian
Introduction
George Dayian is an accomplished inventor based in Albany, NY (US). He has made significant contributions to the field of blood preservation, particularly in the freezing of human blood platelets. With a total of 2 patents, his work has the potential to enhance the efficacy of blood storage and transfusion processes.
Latest Patents
Dayian's latest patents include a method for freezing human blood platelets in glycerol-glucose. This innovative approach utilizes an inexpensive, statically controlled cooling rate device, which comprises a cassette of metal plates and cardboard insulation within a plastic bag. The device is designed to freeze platelets in liquid nitrogen with glycerol-glucose as a cryoprotectant. The cooling rate in the freezing bag varies between 22.1°C and 38.6°C per minute, averaging 33.6°C ± 1.1°C at the center. The post-thaw recovery of platelets frozen with this device and reconstituted in plasma averages 88.6% ± 11.7%, compared to 86.1% ± 9.9% for non-frozen but identically processed platelets. Additionally, the uptake of [^14C]Serotonin after a 0.5-hour incubation was 95.9% ± 1.9% for fresh platelets in platelet-rich plasma, 92.7% ± 4.4% for non-frozen processed platelets, and 81.4% ± 11.8% for frozen platelets, increasing to 85.9% ± 7.7% after one hour of incubation.
