Technique for implanting intramuscular electrodes in the diaphragm by videolaparoscopy in pigs [PDF]

Acta Cirúrgica Brasileira, 2016
PURPOSE: To describe a novel approach for implanting intramuscular electrodes in the diaphragm through videolaparoscopy. METHODS: We used twelve pigs for this videolaparoscopic technique, which permits at the same time to explore the diaphragm, to ...

Instability of synchronized motion in nonlocally coupled neural oscillators

, 2006
We study nonlocally coupled Hodgkin-Huxley equations with excitatory and inhibitory synaptic coupling. We investigate the linear stability of the synchronized solution, and find numerically various nonuniform oscillatory states such as chimera states ...

Extraordinary behavioral entrainment following circadian rhythm bifurcation in mice. [PDF]

, 2016
The mammalian circadian timing system uses light to synchronize endogenously generated rhythms with the environmental day. Entrainment to schedules that deviate significantly from 24 h (T24) has been viewed as unlikely because the circadian pacemaker ...

Myocardial threshold in patients with artificial pacemakers [PDF]

The American Journal of Cardiology, 1966
Abstract A method for estimating myocardial threshold in patients with implanted artificial pacemakers has been described. By the external application of a calibrated suppression signal, the output of the implanted unit can be gradually reduced until the myocardial response ceases. The threshold level thus determined can be expressed as a per cent of

Ionic–Bionic Interfaces: Advancing Iontronic Strategies for Bioelectronic Sensing and Therapy

Advanced Science, EarlyView.
Ionic–bionic interfaces for bioelectronics leverage ions as multifunctional mediators that combine mechanical compliance, ionic and electronic functionalities, and therapeutic effects. These systems offer real‐time biosignal transduction, effective wound dressing, responsive drug delivery, and seamless interaction between soft tissues and electronic ...

Enhanced response of the regular networks to local signals in presence of a fast impurity

, 2012
We consider an array of inductively coupled Josephson junctions with a fast impurity (a junction with a smaller value of critical current), and study the consequences of imposing a small amplitude periodic signal at some point in the array.

Electrical vestibular stimulation in humans. A narrative review [PDF]

, 2019
Background: In patients with bilateral vestibulopathy, the regular treatment options, such as medication, surgery, and/ or vestibular rehabilitation, do not always suffice. Therefore, the focus in this field of vestibular research shifted to electri-

Repurposing of Chemokine Antagonists for Combined Phase‐Resolved Spinal Cord Injury Treatment

Advanced Science, EarlyView.
Spinal cord injury (SCI) in mammals is accompanied by a massive cytokine storm in cerebrospinal fluid, mainly driven by CXCL1, IL‐6, and CCL2‐5. Sub‐acute phase is mostly associated with IL‐2, IL‐7, CCL22, and CX3CL1, whereas TNFα and IL17α permanently persists in CNS even weeks following SCI.

Resilience to Endoplasmic Reticulum Stress Mitigates Membrane Hyperexcitability Underlying Late Disease Onset in a Murine Model of SCA6

Annals of Neurology, EarlyView.
Objective An enduring puzzle in many inherited neurological disorders is the late onset of symptoms despite expression of function‐impairing mutant protein early in life. We examined the basis for onset of impairment in spinocerebellar ataxia type 6 (SCA6), a canonical late‐onset neurodegenerative ataxia which results from a polyglutamine expansion in ...

Electrocardiographic signs of hyperkalemia in a patient with a cardiac pacemaker

Autopsy and Case Reports, 2011
We report the case of a patient with a dual chamber pacemaker admitted to the emergency room with hyperkalemia. Although the pacemaker was present, the classical sings of hyperkalemia can be seen.
