Stress-induced aberrations in sensory processing predict worse cognitive outcomes in healthy aging adults.

It is well recognized that not all individuals age equivalently, with functional dependence attributable, at least in part, to stress accumulated across the lifespan. Amongst these dependencies are age-related declines in cognitive function, which may be the result of impaired inhibitory processing (e.g.

Waves at a fluid-solid interface: Explicit versus implicit formulation of boundary conditions using a discontinuous Galerkin method.

An accurate solution of the wave equation at a fluid-solid interface requires a correct implementation of the boundary condition. Boundary conditions at fluid-solid interface require continuity of the normal component of particle velocity and traction, whereas the tangential components vanish. A main challenge is to model interface waves, namely, the Scholte and leaky Rayleigh waves.

Functional outcome analysis including preoperative and postoperative SF-36 for surgically treated adult isthmic spondylolisthesis.

Study Design: Prospective and retrospective outcome analysis following arthrodesis for adult isthmic spondylolisthesis in 31 patients.

Objective: To examine whether or not patients having such surgery have a functional improvement in their lives.

Summary Of Background Data: The literature is full of articles concerning adolescent spondylolisthesis, the union rate for adult spondylolisthesis, the ability to reduce deformities, and the outcome of surgery for degenerative spondylolisthesis, but very scant on the postoperative functional outcome of adults with isthmic spondylolisthesis.

Measurement accuracy in congenital scoliosis.

Background: The accuracy of measurement of curves in idiopathic scoliosis has been extensively studied; however, we know of only one article in the literature concerning the accuracy of measurement of curves in congenital scoliosis. That article stated that intraobserver variability was +/- 9.6 degrees and interobserver variability was +/- 11.
