Human cytomegalovirus (HCMV) is a frequent cause of major disease following primary infection or reactivation from latency in immunocompromised patients. It has also been suggested that there may be a link between HCMV and vascular disease. Both smooth muscle and endothelial cells are targets for primary infection with HCMV and have also been postulated as potential sites of HCMV latency. One o...

Foeniculum vulgare (fennel) has been widely used in traditional medicine for treatment of variousdiseases including pediatric colic. This study was designed to assess the antinociceptive effects of aqueousextract of F. vulgare on visceral pain and possible involvement of opioidergic, serotonergic, adrenergic andhistaminergic systems. The results of this study showed that aqueous extract of F. v...

The effects of stimulus quality on the amplitude, peak latency, onset latency, and duration of the P300 component of the event-related brain potential were studied in patients with either a left or a right anterior temporal lobectomy and in normal controls. Stimulus quality was reduced by adding "noise" letters to words which signalled either a left or a right hand button press. Consistent with...

Objective: A satellite potential is a late component of the motor unit action potential (MUAP) that occurs both in pathologic and normal muscle. We investigated the physiological mechanisms responsible for satellite potentials in normal muscle by relating the latencies of MUAP features to the timing of the underlying electrical events. Methods: We analyzed 21 MUAPs with satellite potentials tha...

The purpose of the present study was to examine the effects of femoral arterial injections of adenosine on muscle sympathetic nerve activity (MSNA) under three different conditions. These conditions were adenosine injection alone, adenosine injection after phenylephrine infusion, and adenosine injection distal to a thigh cuff inflated to arrest the circulation. The arterial injection of adenosi...

Muscle fatigue due to clenching, grinding is suggested to be in relation to the pain in TMJ dysfunction patients. A number of investigators report that in normal persons experimental muscle fatigue provoked the similar symptoms seen in TMJ dysfunction patients. These reports suggest that muscle fatigue plays a great role in the onset of TMJ dysfunction. The purpose of this study was to investig...

[Purpose] Neuromuscular activity has been evaluated in patellofemoral pain syndrome but movement velocity has not been considered. The aim was to determine differences in onset latency of hip and knee muscles between individuals with and without patellofemoral pain syndrome during a single leg squat, and whether any differences are dependent on movement velocity. [Subjects and Methods] Twenty-f...

It has been suggested that the remote distractor effect is the result of nontarget stimulation of a central region representing a collicular fixation zone near the time of target onset. The distributed network of the cells responsible for this effect is believed to extend over a large area, responding to distractors < or =10 deg in the periphery. Several studies also implicate the superior coll...

STUDY OBJECTIVE Subjective and objective assessments of sleep may be discrepant due to sleep misperception and measurement effects, the latter of which may change the quality and quantity of a person's usual sleep. This study compared sleep times from polysomnography (PSG) with self-reports of habitual sleep and sleep estimated on the morning after a PSG in adults. DESIGN Total sleep time and...

BACKGROUND Carpal tunnel syndrome is the most common peripheral entrapment neuropathy, for which conservative treatments are the first measures taken. However, these measures are not usually sufficient. Recently major attention has been drawn to platelet-rich plasma for its possible effects on axon regeneration and neurological recovery. Although few studies have evaluated the effects of this t...
