We twice tested the hypothesis that top running speeds are determined by the amount of
force applied to the ground rather than how rapidly limbs are repositioned in the air. First, we …

Tumor necrosis factor-alpha (TNF- f ) is pleiotropic mediator of a diverse array of physiological
and neurological functions, including both normal regulatory functions and immune …

Multiple sclerosis (MS) is an inflammatory, neurodegenerative disease of the CNS characterized
by both grey and white matter injury. Microglial activation and a reduction in synaptic …

We tested the importance of aerobic metabolism to human running speed directly by altering
inspired oxygen concentrations and comparing the maximal speeds attained at different …

Loss of synaptic integrity and function appears to underlie neurologic deficits in patients with
HIV-1-associated dementia (HAD) and other chronic neurodegenerative diseases. Because …

Gray matter degeneration contributes to progressive disability in multiple sclerosis (MS) and
can occur out of proportion to measures of white matter disease. Although white matter …

MJ Bellizzi; and MH59745, MH45294, and MH62962 to E. Masliah). MJ Bellizzi is in the …

For both different individuals and modes of locomotion, the external forces determining all-out
sprinting performances fall predictably with effort duration from the burst maximums …

We tested whether the rate at which force is applied to the ground sets metabolic rates during
classical-style roller skiing in four ways:1) by increasing speed (from 2.5 to 4.5 m/s) during …

Microglial activation, increased proinflammatory cytokine production, and a reduction in
synaptic density are key pathological features associated with HIV‐associated neurocognitive …
