The purpose of this study was to investigate the ability of a robotic device, "the rat stepper", to assess intrinsic locomotor recovery following spinal cord contusion injury in adult rats. The device consists of a motorized body weight support mechanism that precisely controls the load to the hindlimbs during stepping, and two small robotic arms that(More)
The genetic control of antibody responses after immunization with Mycobacterium tuberculosis soluble antigens was examined in inbred and H-2 congenic mouse strains. Antibody levels to five distinct epitopes were determined by a competitive inhibition test using radiolabelled murine monoclonal probes. High or low responder antibody levels were associated(More)
The genetic disease cystic fibrosis (CF) is a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, and results in viscous mucus and impaired mucociliary clearance leading to chronic recurring pulmonary infections. Although extensive experimental research has been conducted over the last few decades, CF lung pathophysiology(More)
