EMG responses were recorded from axial muscles transversospinalis, medial longissimus, and lateral longissimus in urethane-anesthetized rats during combined electrical stimulation of the reticular formation and midbrain central gray. Central gray stimulation facilitated reticular formation-evoked EMG activity in the back muscles of the rat. Electrical(More)
Electrical stimulation in the midbrain central gray in urethane-anesthetized female rats increased responses of the deep back muscles lateral longissimus and medial longissimus to stimulation of the lateral vestibular nucleus (LVN). During central gray stimulation, LVN stimuli led to larger muscle responses, recruitment of new motor units, and decreased(More)
The effects of electrical stimulation of the lateral vestibular nucleus (LVN) and medullary reticular formation (RF) on electromyographic activity in axial muscles medial longissimus (ML) and lateral longissimus (LL) in the rat were studied. Long trains (150–500 ms) at 200–330 Hz and 20–100 μA were sufficient to activate ML and LL at latencies of 20–100 ms(More)
Medullary reticular stimulation can activate deep back muscle EMG in urethane-anesthetized female rats. Midbrain central gray stimulation can facilitate brainstem reticular control over deep back muscles. Since these deep back muscles lateral longissimus (LL) and medial longissimus (ML) execute the vertebral dorsiflexion of lordosis behavior, and since the(More)
OBJECTIVE The aim of this study was to prospectively evaluate the ability of a peritoneal equilibration test (PET) performed in the first week of peritoneal dialysis (PD) to predict subsequent transport status, as determined by a PET at 4 weeks and >1 year after PD commencement. DESIGN Prospective observational study of an incident PD cohort at a single(More)
It has been known for years that mixing household cleaning products can be hazardous. Nonetheless, from time to time, episodes of pneumonitis from such mixing occur. Although symptoms range from minor upper respiratory irritation to adult respiratory distress syndrome, deaths are very rare. We present the case of a woman with an undiagnosed(More)
A 27-year-old white woman with a history of multiple sclerosis was found dead lying on a lounger, clad in a bathing suit. She had been sunbathing for 4 hours. Significant autopsy findings consisted of numerous variably sized demyelinated plaques involving the periventricular cerebral white matter and cerebellum. Elevation of core temperature in patients(More)
Lipoma of the internal auditory canal is a rare tumor that may be confused clinically with the much more common vestibular schwannoma. We present two cases of lipoma of the internal auditory canal. The clinical presentation is indistinguishable from that of vestibular schwannomas. The high signal intensity on T1-weighted magnetic resonance imaging, both(More)
