background: s1 radiculopathy is a high prevalence illness and its early diagnosis is of crucial importance. several reports have revealed the efficacy of magnetic stimulation in diagnosis of this condition. we conducted this study to compare mmep latency and mmep amplitude in patients with s1 radiculopathy and healthy controls in shohadaye tajreash hospital in 2007. materials and methods: this ...

Membrane metalloendopeptidase (MMEP; EC 3.4.24.11; enkephalinase) catalyzes the degradation of endothelins, enkephalins, atrial natriuretic factor, substance P, and other small bioactive peptides. We found that MMEP is present in human endometrium, localized primarily in stromal cells of this tissue, and that the specific activity of MMEP (and immunoreactive MMEP protein) in endometrial tissue ...

OBJECTIVE The main aim of the present study is to examine the electrode configurations used to record the muscle motor evoked potential (mMEP) in the upper extremities during surgery with the goal of producing a high and stable mMEP signal, in particular among the abductor pollicis brevis (APB), abductor digiti minimi (ADM), and across the APB-ADM muscles, which have been widely used for the mM...

OBJECTIVE To evaluate whether the combination of muscle motor evoked potentials (mMEPs) and somatosensory evoked potentials (SEPs) measured during spinal surgery can predict immediate and permanent postoperative motor deficits. METHODS mMEP and SEP was monitored in patients undergoing spinal surgery between November 2012 and July 2014. mMEPs were elicited by a train of transcranial electrical...

A patient with microcephaly, microphthalmia, ectrodactyly, and prognathism (MMEP) and mental retardation was previously reported to carry a de novo reciprocal t(6;13)(q21;q12) translocation. In an attempt to identify the presumed causative gene, we mapped the translocation breakpoints using fluorescence in situ hybridisation (FISH). Two overlapping genomic clones crossed the breakpoint on the d...

Brachial plexus trauma is a common clinical entity in small animal practice and prognostic indicators are essential early in the course of the disease. Magnetic stimulation of the radial nerve and consequent recording of the magnetic motor evoked potential (MMEP) was examined in 36 dogs and 17 cats with unilateral brachial plexus trauma. Absence of deep pain perception (DPP), ipsilateral loss o...

CONTEXT Increasing the number of minority physicians is a long-standing goal of professional associations and government. OBJECTIVE To determine the effectiveness of an intensive summer educational program for minority college students and recent graduates on the probability of acceptance to medical school. DESIGN Nonconcurrent prospective cohort study based on data from medical school appl...

Figure 2. (a) In vivo acute axial diffusivity (λ||) maps of control (I and II) and SCI (1.0 mm (III), 1.25 mm (IV), and 1.5 mm (V) cords. (b – d) Electrophysiology measurements . (e – g) MMEP at 4wks after SCI. (h – k) MIER at 4wks after SCI. Panel a-I and a-II shows ROIs for descending (ROI 1 and 2) and ascending (ROI 3 and 4) tracts respectively. Each ROI is divided into inner (ROI 2 and 3) a...

The goal of this study was to characterize the utility of muscle motor evoked potentials (MMEPs) elicited by direct cortical stimulation as a means of monitoring during unruptured large and giant cerebral aneurysm surgery. This analysis focused on intraoperative changes in MMEPs and their relationship to postoperative motor function. The study population consisted of 50 patients who underwent s...
