121. Feasibility and effects of intra-dialytic low-frequency electrical muscle stimulation and cycle training: A pilot randomized controlled trial. Full Text available with Trip Pro

Feasibility and effects of intra-dialytic low-frequency electrical muscle stimulation and cycle training: A pilot randomized controlled trial. Exercise capacity is reduced in chronic kidney failure (CKF). Intra-dialytic cycling is beneficial, but comorbidity and fatigue can prevent this type of training. Low-frequency electrical muscle stimulation (LF-EMS) of the quadriceps and hamstrings elicits a cardiovascular training stimulus and may be a suitable alternative. The main objectives

124. Regulation of oxidative phosphorylation is different in electrically- and cortically-stimulated skeletal muscle. Full Text available with Trip Pro

Regulation of oxidative phosphorylation is different in electrically- and cortically-stimulated skeletal muscle. A computer model of the skeletal muscle bioenergetic system was used to study the regulation of oxidative phosphorylation (OXPHOS) in electrically-stimulated and cortically-stimulated skeletal muscle. Two types of the dependence of the intensity of each-step activation (ESA) of OXPHOS complexes on ATP usage activity were tested: power-type dependence and saturating-type dependence (...) . The dependence of muscle oxygen consumption ([Formula: see text]), phosphocreatine (PCr), cytosolic ADP, ATP, inorganic phosphate (Pi), pH and τp (characteristic transition time) of the principal component of the muscle [Formula: see text] on-kinetics on the ATP usage activity was simulated for both types of the ESA intensity-ATP usage activity dependence. Computer simulations involving the power-type dependence predict system properties that agree well with experimental data for electrically-stimulated

125. Electrical field stimulation-induced contractions on Pantherophis guttatus corpora cavernosa and aortae. Full Text available with Trip Pro

Electrical field stimulation-induced contractions on Pantherophis guttatus corpora cavernosa and aortae. A tetrodotoxin (TTX)-resistant mechanism is responsible for the electrical field stimulation (EFS)-induced contractions and relaxations of Crotalus durissus terrificus corpora cavernosa. Here it was investigated whether this mechanism also occurs in corpora cavernosa and aortae of the non-venomous snake Pantherophis guttatus corpora cavernosa and aortae. Corpora cavernosa and aortic rings (...) isolated from Pantherophis guttatus snake were mounted in organ bath system for isometric tension recording. EFS-induced contractions in both tissues were performed in the presence and absence of guanethidine (30 μM), phentolamine (10 μM) and tetrodotoxin (1 μM). In another set of experiments, the endothelium was removed from aortic rings and EFS-induced contractions were performed in the denuded rings. Electrical field stimulation-induced contractions were frequency-dependent in Pantherophis guttatus

128. Communication calls produced by electrical stimulation of four structures in the guinea pig brain. Full Text available with Trip Pro

Communication calls produced by electrical stimulation of four structures in the guinea pig brain. One of the main central processes affecting the cortical representation of conspecific vocalizations is the collateral output from the extended motor system for call generation. Before starting to study this interaction we sought to compare the characteristics of calls produced by stimulating four different parts of the brain in guinea pigs (Cavia porcellus). By using anaesthetised animals we were (...) able to reposition electrodes without distressing the animals. Trains of 100 electrical pulses were used to stimulate the midbrain periaqueductal grey (PAG), hypothalamus, amygdala, and anterior cingulate cortex (ACC). Each structure produced a similar range of calls, but in significantly different proportions. Two of the spontaneous calls (chirrup and purr) were never produced by electrical stimulation and although we identified versions of chutter, durr and tooth chatter, they differed

130. Compartment models for the electrical stimulation of retinal bipolar cells. Full Text available with Trip Pro

Compartment models for the electrical stimulation of retinal bipolar cells. Bipolar cells of the retina are among the smallest neurons of the nervous system. For this reason, compared to other neurons, their delay in signaling is minimal. Additionally, the small bipolar cell surface combined with the low membrane conductance causes very little attenuation in the signal from synaptic input to the terminal. The existence of spiking bipolar cells was proven over the last two decades, but until now (...) required at least a separate axon compartment. At least a four compartment model containing the functionally different segments dendrite, soma, axon and terminal was needed for understanding signaling in spiking bipolar cells. Whereas for intracellular current application models with small numbers of compartments showed quantitatively correct results in many cases, the cell response to extracellular stimulation is sensitive to spatial variation of the electric field and accurate modeling therefore

135. Pacemaker Essentials: How to Interpret a Pacemaker ECG

. This is failure to pace (FTP). STEP 4: Are there pacing spikes where there shouldn’t be? If your intrinsic cardiac rhythm is appropriate, your pacemaker should just sit back and relax. If you start seeing paced spikes during normal cardiac activity, this means the pacemaker isn’t sensing myocardial depolarization and thus is failing to sense (or under-sensing) the native rhythm! Figure 4. Pacing spikes are seen despite normal electrical activity. This is failure to sense (FTS or under-sensing). Let’s Talk (...) pacing spikes do not result in depolarization of the myocardium. This is failure to capture (FTC). STEP 3: Are there are pacer spikes seen throughout with no sinus pauses or asystole? If the pacemaker is pacing properly, there should be no periods where you see a sinus pause or asystole. The pacemaker should provide an electrical impulse when a set time interval has been reached. If it does not, this is failure to pace (FTP)! Figure 3. There is a long pause with no pacing spike delivered

Measurements and models of electric fields in the in vivo human brain during transcranial electric stimulation Transcranial electric stimulation aims to stimulate the brain by applying weak electrical currents at the scalp. However, the magnitude and spatial distribution of electric fields in the human brain are unknown. We measured electric potentials intracranially in ten epilepsy patients and estimated electric fields across the entire brain by leveraging calibrated current-flow models. When (...) stimulating at 2 mA, cortical electric fields reach 0.4 V/m, the lower limit of effectiveness in animal studies. When individual whole-head anatomy is considered, the predicted electric field magnitudes correlate with the recorded values in cortical (r = 0.89) and depth (r = 0.84) electrodes. Accurate models require adjustment of tissue conductivity values reported in the literature, but accuracy is not improved when incorporating white matter anisotropy or different skull compartments.

137. Age-related changes in cortical connectivity influence the neuromodulatory effects of transcranial electrical stimulation. (Abstract)

Age-related changes in cortical connectivity influence the neuromodulatory effects of transcranial electrical stimulation. Transcranial electrical stimulation (tES) is a potentially viable tool for boosting cognitive performance in aging. However, most knowledge on tES effects is based on studies involving young adults. Here, we applied tES (transcranial random noise stimulation [tRNS] as an effective stimulation and anodal transcranial direct current stimulation [atDCS] as a "control (...) " stimulation) to the visual cortex during visual perceptual learning (VPL) in healthy young and older individuals. Moreover, we measured transcranial magnetic stimulation-evoked potentials to investigate the neurophysiological underpinnings of tES effects. We found that only the tRNS in the young, but not in the older, subjects modulated VPL, by decreasing performance. Transcranial magnetic stimulation-evoked potentials revealed age-related changes in connectivity, that is, a stronger activation

140. Efficacy of transcutaneous electrical nerve stimulation in the treatment of chronic pelvic pain. Full Text available with Trip Pro

Efficacy of transcutaneous electrical nerve stimulation in the treatment of chronic pelvic pain. Chronic pelvic pain is prevalent in 2% of women population globally. The etiology is multifactorial. Even in the absence of pelvic pathology, there is a subgroup of women who do not respond to analgesic and anti-inflammatory therapy. Chronic pelvic pain can be inhibited by direct inhibition of impulses in the preganglionic afferent neuron by closing the hypothetical gate in the dorsal horn (...) of the spinal cord. Transcutaneous electrical nerve stimulation (TENS) is based on the gate control theory of abolishing the painful stimuli by providing simultaneous inputs in larger myelinated nerve fibers.This study was designed to assess the effectiveness and safety of TENS in idiopathic chronic pelvic pain.It is a prospective, experimental study to evaluate the effectiveness of TENS versus placebo in reducing pain severity in chronic pelvic pain (G1 = 30, G2 = 32, G3 = 30, and G0 = 30).
