Abstract:

The immediate effects of phrenic afferent nerve activation on ventilation have been shown to be both excitatory and inhibitory. Long-lasting inhibitory effects on respiratory motoneuron output have been reported after stimulation of afferent nerves from limb muscles. However, whether respiratory muscle afferent nerves can produce this effect is unknown. We therefore hypothesized that activation of phrenic afferent nerves may produce a prolonged decrease of respiratory motoneuron output. Six alpha-chloralose-anesthetized dogs were studied after vagotomy and bilateral carotid sinus nerve section

Abstract:

151 Background: T-cell therapy for cancer faces several challenges, including limited T-cell expansion at tumor sites, and lack of unique tumor antigens that are not expressed in normal tissues. To overcome the first obstacle, we developed Engager (ENG) T cells, which secrete bispecific molecules consisting of single chain variable fragments specific for CD3 and a tumor antigen. ENG T cells have the unique ability to redirect bystander T cells to tumors, amplifying antitumor effects. Costimulatory chimeric antigen receptors (CoCARs) are one potential strategy to restrict full T-cell activation

Almitrine increases breathing by stimulating peripheral chemoreceptors.

We investigated the effect of intravenous almitrine on hypoglossal (HG), an upper airway nerve, and phrenic (PHR) neural activity in eight alpha-chloralose-urethan anesthetized, paralyzed, vagotomized, and artificially ventilated cats.

Abstract Background: Immunotherapy with anti-CD19/anti-CD3 bispecific engager molecules has shown promise in clinical studies for CD19+ malignancies. However engager molecules have short half-lives and do not accumulate at tumor sites. In addition, co-delivery of other immunostimulatory molecules to enhance antitumor effects is difficult to achieve. We have recently shown that T cells can be genetically modified to secrete bispecific engager molecules (ENG-T cells).

Abstract:

The synaptic pathways of mesencephalic locomotor region (MLR)-evoked excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs) recorded from lumbar motoneurons of unanesthetized decerebrate cats during fictive locomotion were analyzed prior to, during, and after cold block of the medial reticular formation (MedRF) or the low thoracic ventral funiculus (VF). As others have shown, electrical stimulation of the MLR typically evoked short-latency excitatory or mixed excitatory/inhibitory PSPs in flexor and extensor motoneurons. The bulbospinal conduction velocities averaged ∼88 m/s (rang

Abstract:

Transcranial Current Stimulations (tCSs) are non-invasive brain stimulation techniques which modulate cortical excitability and spontaneous brain activity by the application of weak electric currents through the scalp, in a safe, economic, and well-tolerated manner. The direction of the cortical effects mainly depend on the polarity and the waveform of the applied current. The aim of the present work is to provide a broad overview of recent studies in which tCS has been applied to modulate sleepiness, sleep, and vigilance, evaluating the efficacy of different stimulation techniques and protoco

Abstract:

Brain Computer Interface (BCI) is a new ways of communicating with outside for the loss of some or all of the muscles controlling function of the patients. And the BCI is to set up a new information communication and control channel though the computer or other electronic device between the human brain and the external environment that does not depend on the peripheral nerve and muscle tissue. Firstly, this paper studies the methods of visual stimulation based on Brain Computer Interface that classified by stimulating form can be divided into flash simulation and figures simulation and classif

Abstract:

AbstractBackground: When H-reflexes are recorded during movement in human subjects, the stimulator current output is not a good indicator of sensory stimulation efficacy because of unavoidable nerve movement relative to the stimulus electrodes. Therefore, the M-wave amplitude has been used by researchers as an indicator of the efficacy of the stimulus. In this study we have examined the general validity of the hypothesis that the M-wave amplitude is directly proportional to the group I sensory afferent volley evoked by the stimulus.

Abstract:

The effects of color are already being used widely. For this reason, in this study, an attempt was made to use such effects of color to examine the changes in sleep onset through the use of the preferred and nonpreferred color light stimulation. Color light stimulations were randomly presented to the subjects, and based on these colors, the changes in sleep onset were examined through the EEG. Also, to quantify the physiological changes that were caused by each color light stimulation, the changes in the HRV were examined through ECG to determine the level of activation of the autonomous nervo

Abstract:

Stereotactic deep brain stimulation (DBS) of the thalamus and the subthalamic region has been shown to be effective in treating medically refractory tremor over the past few decades. In this article we discuss the merits and drawbacks of stimulating each of the targets in this region, in particular the caudal zona incerta nucleus (cZI). We discuss our recent work in this field and the rationale behind choosing this nucleus to implant bilateral DBS leads for all forms of tremor.

Abstract:

Hallmarks of the mammalian diving response are protective apnea and bradycardia. These cardiorespiratory adaptations can be mimicked by stimulation of the trigeminal ethmoidal nerve (EN5) and reflect oxygen-conserving mechanisms during breath-hold dives. Increasing drive from peripheral chemoreceptors during sustained dives was reported to enhance the diving bradycardia. The underlying neuronal mechanisms, however, are unknown. In the present study, expression and plasticity of EN5-bradycardias after paired stimulation of the EN5 and peripheral chemoreceptors was investigated in the in situ wo

Abstract:

The effects of biphasic electric fields on nerve regeneration that follows injury to the left radial nerve were studied in dogs by electromyography (EMG). Left and right radial nerves were crushed with a serrated haemostat. Stimulating electrodes were positioned proximally and distally to the site of the injury. The left nerves received rectangular, biphasic and current pulses (30 µA, 0.5 Hz) through the injury for two months. The right radial nerves were treated as controls and regenerated without electrical stimulation. EMG activities were recorded intramuscularly from the left and right mus

We examined the ability of muscular and joint afferents from the hip region to entrain fictive locomotion evoked by stimulation of the mesencephalic locomotor region in the decerebrate cat by mechanically imposed, sinusoidal hip flexion and extension movements. 2. A method is presented for qualitative and quantitative analysis of entrainment. 3. Hip joint capsular afferents were shown by denervation experiments to be unnecessary for mediating locomotor entrainment. 4. As the population of muscular afferents was progressively decreased by selective denervation, the strength of entrainment co

Background: Even in the case of minimally invasive pelvic surgery, sparing of the autonomic nerve supply is a prerequisite for maintaining anal sphincter function. Internal anal sphincter (IAS) innervation could be electrophysiologically identified based on processed electromyographic (EMG) recordings with conventional bipolar needle electrodes (NE). This experimental study aimed for the development of a minimally invasive approach via intra-anal surface EMG for recordings of evoked IAS activity.
