[Purpose] Painful diabetic polyneuropathy occurs as a complication in 16% of all patients with diabetes mellitus. [Subjects and Methods] A clinical, prospective open-label randomized intervention study was conducted of 60 adult patients, with distal sensorimotor diabetic neuropathy two groups of 30 patients, with diabetes mellitus type 2 with distal sensorimotor diabetic neuropathy. Patients in...
OBJECTIVE To evaluate conduction abnormalities in the nerves innervating the proximal muscles in demyelinating neuropathies (DN) using cervical magnetic stimulation. METHODS We applied cervical root magnetic stimulation in the biceps brachii muscles and examined its activity-dependent conduction changes produced by maximal voluntary contraction (MVC) in 12 DN patients (seven chronic inflammat...
Introduction Hearing loss is the most common clinical finding in patients with malformation of the external ear canal. Among the possibilities of treatment, there is the adaptation of hearing aids by bone conduction and the adaptation of implantable hearing aids. Objective To assess speech perception with the use of Vibrant Soundbridge (VBS - MED-EL, Innsbruck, Austria) associated with addition...
Voltage-dependent sodium (Na(+)) channels are heterogeneously distributed through the pacemaker of the heart, the sinoatrial node (SA node). The measured sodium channel current (i(Na)) density is higher in the periphery but low or zero in the center of the SA node. The functional roles of i(Na) in initiation and conduction of cardiac pacemaker activity remain uncertain. We evaluated the functio...
The realization of ultra-low power Si-based resistive switching memory technology will be a milestone in the development of next generation non-volatile memory. Here we show that a high performance and ultra-low power resistive random access memory (RRAM) based on an Al/a-SiNx:H/p(+)-Si structure can be achieved by tuning the Si dangling bond conduction paths. We reveal the intrinsic relationsh...
Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...
SUMMARY A combined electrophysiologic-anatomic study was performed in a dog with a congenital atrial septal defect (ASD) primum. Comparisons were made between the dog and electrophysiologic data obtained in four patients with ASD primum. The ECGs and VCGs in both the dog and patients revealed the characteristic features of superior orientation, counterclockwise rotation, and slow-rightward term...
Seven multiple sclerosis subjects had their silver dental fillings (amalgams) removed which contained approximately 50% mercury. A visual evoked response (VER) test was performed before amalgam removal. Approximately six months after amalgam removal a second VER test was performed on all subjects, and the latencies of the VER decreased significantly. The mean latency of P1 for the right and lef...
Background & Aim: The most common surgically treatable causes of hearing loss are middle ear diseases among which the greatest effect is related to ossicular chain dysfunction. Successful ossicular chain reconstruction certainly improves air conduction thresholds and closes air-bone gap in audiograms, but the effect of this procedure on bone conduction thresholds has remained to be elucidat...
