Troponins are found in all muscle cells, but troponin T -- normally less than 0.2 mcg/L -- and I -- normally less than 0.35 mcg/L -- are more specific to heart muscle. Creatine kinase -- normally 0 to 3 mcg/L -- helps to regenerate used ATP. Lactate dehydrogenase helps in energy metabolism.
From Wikipedia, the free encyclopedia. In tort law, a duty of care is a legal obligation which is imposed on an individual requiring adherence to a standard of reasonable care while performing any acts that could foreseeably harm others.n turn, breaching a duty may subject an individual to liability. The duty of care may be imposed by operation of law between individuals with no current direct relationship (familial or contractual or otherwise), but eventually become related in some manner, as defined by common law (meaning case law).
A fiduciary duty is the highest standard of care at either equity or law.
