Materials chemistry: a synthetic enamel for rapid tooth repair.

abstract：:Much of our current knowledge about mitochondria has come from studying patients who have respiratory chain disorders. These disorders comprise a large collection of individually rare syndromes, each presenting in a unique and often devastating way. In recent years, there has been great progress in defining their gene...
