Organ harvesting from Falun Gong practitioners in China must be taken from a living donor (kidneys must be transplanted within 24–48 hours; livers within 12 hours, and hearts within 8 hours). Kirk C. Allison, Associate Director of the Program in Human Rights and Medicine at the University of Minnesota, wrote that the "short time frame of an on-demand system [as in China] requires a large pool of donors pre-typed for blood group and HLA matching," which is consistent with reports of Falun Gong prisoners having blood and tissue tested in custody. He wrote that China's short organ wait times could not be assured on a “random death” basis,
Blood–brain barrier more likely, aggravated) by a breakdown in the blood–brain barrier. Cerebral edema is the accumulation of excess water in the extracellular space of the brain, which can result when hypoxia causes the blood–brain barrier to open. Many neurodegenerative diseases including synucleinopathies such as Parkinson's, and tauopathies such as Alzheimer's are thought to result from seeded misfolding from pathological extracellular protein variants known as prions. This prion-like hypothesis is gaining support in numerous studies in vitro and involving in vivo intracerebral injection of brain lysates, extracted protein (tau, alpha-synuclein) and synthetically generated fibers in alpha-synucleinopathies. These proteins are also detectable in
