Improving uncertainty tolerance in medical students: A scoping review.

Introduction: Uncertainty is an inevitable part of medical practice. An ability to tolerate uncertainty is viewed as a key competency across many health-care systems. Poor uncertainty tolerance (UT) has been linked to negative outcomes including reduced psychological well-being in medical students.

How well do muscle biomechanics predict whole-animal locomotor performance? The role of Ca2+ handling.

It is important to determine the enabling mechanisms that underlie locomotor performance to explain the evolutionary patterns and ecological success of animals. Our aim was to determine the extent to which calcium (Ca(2+)) handling dynamics modulate the contractile properties of isolated skeletal muscle, and whether the effects of changing Ca(2+) handling dynamics in skeletal muscle are paralleled by changes in whole-animal sprint and sustained swimming performance. Carp (Cyprinus carpio) increased swimming speed by concomitant increases in tail-beat amplitude and frequency.
