BACKGROUND AND OBJECTIVES While content, navigability, and usability are essential qualities of effective Web sites, the health care literature contains limited discussion of these issues. This article describes how knowledge gained through focus groups, Web site searches, and individual interviews were used to develop and improve a health-related Web site. METHODS We conducted 10 focus group...
Three experiments were conducted to evaluate the effect of 1-Hzbrain stimulation of the amygdala on kindling behavior induced by 60-Hz sine-wave stimulation in the contralateral amygdala. In Experiment 1, the effective threshold intensity (ETI) to elicit a kindled response with 60-Hz stimulation was determined on four separate occasions with 15 trials between determinations (three per day) for ...
BACKGROUND Subthalamic nucleus (STN) stimulation has been recognized to control resting tremor in Parkinson disease. Similarly, thalamic stimulation (ventral intermediate nucleus; VIM) has shown tremor control in Parkinson disease, essential, and intention tremors. Recently, stimulation of the posterior subthalamic area (PSA) has been associated with excellent tremor control. Thus, the optimal ...
Vimentin intermediate filaments undergo spatial reorganization in endothelial cells and fibroblasts in response to stimulation with platelet-derived growth factor and epidermal growth factor. In the present study, the vimentin network exhibited a curved filamentous structure in unstimulated smooth muscle cells. Vimentin filaments became straight and were arranged along the long axis of cells up...
The influence of activation sequences on action potential configuration, especially in the repolarization phase, was examined in isolated canine ventricular muscles. Action potentials were recorded from the epicardial surface in the center of a preparation having nearly uniform fiber orientation (25 X 25 mm). Stimuli applied just adjacent to the recording site produced nearly centrifugal propag...
