Spontaneous contractions of the urinary bladder (SBCs) have been shown to decrease the frequency and depth of respiration in anesthetized or unanesthetized, decerebrate cats. The respiratory responses to bladder voiding reflexes in the awake state have not been previously addressed. Because a chronic rat model for the study of bladder function has been(More)
New residential developments in the Southeastern United States peaked in early 2006, but since then declined leaving numerous residential developments stalled in various stages of construction. The status of 119 previously identified (2009) abandoned residential housing developments was reinvestigated in 2013 using the most current available high-resolution(More)
BACKGROUND Traumatic hemopericardium remains a rare entity; it does however commonly cause cardiac tamponade which remains a major cause of death in traumatic blunt cardiac injury. OBJECTIVES We present a case of blunt chest trauma complicated by cardiac tamponade causing cardiac chamber equalization revealed by reflux of contrast. CASE REPORT A(More)
OBJECTIVE The goal of this case report is to characterize injury patterns typical for chainsaw injuries to the face. We describe our approach to the soft tissue and skeletal injury patterns seen in these injuries. METHODS We present a case report of a traumatic chainsaw injury to the face. RESULTS A literature review of the typical injury patterns seen(More)
Since stimuli from abdominal or pelvic viscera can affect respiratory muscle function, we hypothesized that mechanical stimulation of the gallbladder would result in inhibition of motor activity to the diaphragm and to upper airway muscles. We studied 12 decerebrate, vagotomized, paralyzed, artificially ventilated cats and recorded hypoglossal (HG) and(More)
We investigated the role of V(T) and V(T)/T(I) modulation of breathing in awake human subjects. We applied a PRBS of volume (incrementing ramp) or flow (decrementing wave) assist at levels below the perceptual threshold in order to stimulate respiratory feedback. We modeled the PRBS data with linear difference equations to obtain impulse-response profiles(More)
