Factors influencing accruement of contact hours for nurses.

Background: A decline in attendance at continuing education (CE) in nursing activities was observed in a Midwest state where CE attendance is not required.

Purpose: The purpose of this research study was to identify the effect of attitude, extrinsic and intrinsic reinforcement, and deterrents on contact hour accrual.

Methods: A convenience sample of 282 registered nurses was surveyed using a researcher-constructed instrument determined to be valid and reliable.

Altered distribution of myosin isoenzymes in the cardiomyopathic Syrian hamster (BIO 8.262).

Myosin of the ventricular myocardium of the cardiomyopathic Syrian hamster and of control animals was analysed using non-dissociating pyrophosphate electrophoresis. Three different myosin isoenzymes exhibiting different Ca2+ activated ATPase activities were demonstrated in the ventricular myocardium of the Syrian hamster. As shown by peptide mapping, ventricular myosin isoenzymes differ in their heavy chain composition.
