Title of dissertation: THE DYNAMICS OF MULTI-SENSORY RE-WEIGHTING IN HEALTHY AND FALL-PRONE OLDER ADULTS Leslie K. Allison, Doctor of Philosophy, 2006 Dissertation directed by: Professor John J. Jeka Department of Kinesiology Multi-sensory re-weighting (MSR) is an adaptive process that prioritizes the visual, vestibular and somatosensory inputs that provide the most reliable information when en...

As the population of older adults increases, healthy aging has become a global public health issue. Physical activity can help older adults reclaim or maintain a healthy aging process. The purpose of this paper is to investigate the relationship between physical activity, physical performance, quality of life and cognition in non-frail adults aged 65 and older. English articles in peer-reviewed...

Invertebrate iridescent virus 6 (IIV6) was determined to cause infection in Phyllophaga vandinei Smyth (Coleoptera: Scarabaeidae) through a range of modes of transmissions. This is the first evidence of IIV6 infection in P. vandinei that caused both patent and sub-lethal infections in larvae and adults. Mortality rates were determined to be ~30% when virus inoculum was injected into larvae or a...

The ability to maintain information over short periods of time (i.e., working memory) is critically important in a variety of cognitive functions including language, planning, and decision-making. Recent functional Magnetic Resonance Imaging (fMRI) research with healthy adults has shown that brain activations evoked during the delay interval of working memory tasks can be reduced by the present...

BACKGROUND Gait impairments are well documented in those with PD. Prior studies suggest that gait impairments may be worse and ongoing in those with PD who demonstrate FOG compared to those with PD who do not. PURPOSE Our aim was to determine the effects of manipulating step length and cadence individually, and together, on gait coordination in those with PD who experience FOG, those with PD ...

  Background :Soft tissue profile can be widely different in various populations. Furthermore, this profile can be also continues to change throughout life. However, there are few studies that quantitatively evaluate the soft tissue profile in Iranian population. In order to determine normal reference values of facial parts in our populations, we aimed to measure standards for facial soft tissu...

Compartment pressures have not previously been studied in healthy children. We compared the pressures in the four lower leg compartments of healthy children with those of healthy adults. We included patients aged between two months and six years, and measured the pressures in 80 compartments of 20 healthy children using simple needle manometry. Measurements were repeated in a control group of 2...

The present study investigated delay discounting and probability discounting-behavioral economic indices of impulsivity and risk proneness, respectively-in 39 healthy older adults and 25 older adults with mild cognitive impairment (MCI). Relative to the healthy group, it was hypothesized that older adults with MCI would display greater levels of impulsivity, risk proneness, and response inconsi...

aim : this study evaluated serum levels of zinc in patient with cd compare to healthy subjects. background : celiac disease (cd) is characterized by small intestinal malabsorption of nutrients as a consequence of ingestion of wheat gluten. zinc is an essential trace element that it has vital biological functions. patients and methods : sera of 30 celiac cases and 30 healthy normal cohorts as co...
