Clinical Laboratory Tycoon case study: are you management material?

Objective: Many clinical laboratory scientists find themselves in a management position during their career, but have limited training to assume this role. The Clinical Laboratory Tycoon case study was designed to submerge students into the laboratory business by having the participant act as a laboratory manager with the capacity to make all the decisions about his or her own lab.

Design: The student participant completed a set of modules that each related to varying aspects of managing a laboratory including selecting what tests to offer, hiring employees, marketing the services, setting goals, budgeting, and evaluating overall success.

A selective role for MRF4 in innervated adult skeletal muscle: Na(V) 1.4 Na+ channel expression is reduced in MRF4-null mice.

The factors that regulate transcription and spatial expression of the adult skeletal muscle Na+ channel, Na(V) 1.4, are poorly understood. Here we tested the role of the transcription factor MRF4, one of four basic helix-loop-helix (bHLH) factors expressed in skeletal muscle, in regulation of the Na(V) 1.
