New study in 'Nature' demonstrates protection against cell death during heart attack
...s discovered that blocking a particular protein in mice protects the heart from injury due to loss of blood flow during a heart attack. Moreover, drugs already exist that block this protein cyclophilin D but they have never been used in actual patient care, partially because data didn't exist until now...UCSF study offers insight into human circadian rhythms
