New Uncertainties Around Irreversible Brain Cell Death Following Oxygen Deprivation? (BBC News / Nature)
Summary Conventional medical wisdom holds that brain cells and working brain circuitry are prone to irreversible damage following merely minutes of interrupted blood flow and disrupted oxygen supply. Researchers at Yale University used an extracorporeal pulsatile-perfusion system to restore circulation in … Continue reading

Further Research Backs Speculation Linking the Immune System and Parkinson’s Disease (BBC News / Nature)
Summary Further evidence has emerged suggesting that malfunctioning in the body’s immune system may contribute to the development and progression of Parkinson’s Disease. T-cells appear to attack alpha-synuclein – a protein which accumulates in Parkinson’s Disease – after confusing this … Continue reading
