The combination of high temperature and very high pressure in the preparation of processed meats such as hot dogs and salami may effectively reduce the presence of infective prions while retaining the taste, texture, and look of these meats, according to a study in today?s Proceedings of the National Academy of Sciences (PNAS) Early Edition.
An electrical problem in the heart may cause one out of 20 cases of sudden infant death syndrome (SIDS), researchers have reported.
The problem is similar to a heart condition called long Q-T syndrome that contributes to sudden death in young people and adults. In long Q-T syndrome, the heart electrically recharges itself too slowly or in a disorganized fashion in preparation for the next heartbeat. When combined with a trigger, such as intense emotion or physical exertion, a long Q-T heart can go out of control and cause cardiac arrest and sudden death.
