On the action potential as a propagating density pulse and the role of anesthetics [PDF]
Biophys. Rev. Letters 2 (2007) 57-78, 2006 The Hodgkin-Huxley model of nerve pulse propagation relies on ion currents through specific resistors called ion channels. We discuss a number of classical thermodynamic findings on nerves that are not contained in this classical theory. Particularly striking is the finding of reversible heat changes, thickness and phase changes of the membrane during ...

Propofol affords no protection against delayed cerebral ischemia in a mouse model of subarachnoid hemorrhage [PDF]
, 2023 Delayed cerebral ischemia (DCI) is an important contributor to poor outcomes in aneurysmal subarachnoid hemorrhage (SAH) patients. We previously showed that volatile anesthetics such as isoflurane, sevoflurane and desflurane provided robust protection ...

The thermodynamics of lipid ion channel formation in the absence and presence of anesthetics. BLM experiments and simulations [PDF]
Soft Matter, 2009, 5: 3319-3330, 2009 It is known that lipid membranes become permeable in their melting regime. In microscopic conductance measurements on black lipid membranes one finds that conduction takes place via quantized events closely resembling those reported for protein ion channels. Here, we present data of ion currents through black lipid membranes in the presence and absence

BMC Medical Imaging, 2012 Background Although general anesthesia is widely used in the surgical arena, the mechanisms by which general anesthetics act remain unclear. We previously described alterations in gene expression ratios in hepatic tissue taken from rats treated with ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Febrile infection related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus with immune dysregulation as a potential pathologic mechanism. Despite promising results from second‐line immunomodulators, approximately 30% remain refractory to treatment.

Perioperative and anesthetic deaths: toxicological and medico legal aspects [PDF]
, 2019 Background: Anesthesia has become safer during decades, though there is still a preventable mortality; the complexity of medical and surgical interventions, increasingly older and sicker patients, has created a host of new hazards in anesthesiology.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Music interventions have been shown to have beneficial effects on hemodynamic parameters, pain, and anxiety in various medical settings. However, music interventions in the setting of acute stroke have not been studied. The objective of this trial was to perform a pilot feasibility study of music interventions in the setting of acute
