Physical disuse contributes to widespread chronic mechanical hyperalgesia, tactile allodynia, and cold allodynia through neurogenic inflammation and spino-parabrachio-amygdaloid pathway activation.

Pain 2020 Mar 13. Epub 2020 Mar 13.

Department of Anatomy, Aichi Medical University, Aichi 480-1195, Japan.

Physical disuse could lead to a state of chronic pain typified by complex regional pain syndrome type I due to fear of pain through movement (kinesiophobia) or inappropriate resting procedures. However, the mechanisms by which physical disuse is associated with acute/chronic pain and other pathological signs remain unresolved. We have previously reported that inflammatory signs, contractures, disuse muscle atrophy, spontaneous pain-like behaviors, and chronic widespread mechanical hyperalgesia based on central plasticity occurred after 2-weeks of cast immobilization in chronic post-cast pain (CPCP) rat model.

Pituitary Adenylate Cyclase-Activating Peptide (PACAP)-Glutamate Co-transmission Drives Circadian Phase-Advancing Responses to Intrinsically Photosensitive Retinal Ganglion Cell Projections by Suprachiasmatic Nucleus.

Front Neurosci 2019 6;13:1281. Epub 2019 Dec 6.

Neuroscience Program, University of Illinois at Urbana-Champaign, Urbana, IL, United States.

Results from a variety of sources indicate a role for pituitary adenylate cyclase-activating polypeptide (PACAP) in light/glutamate-induced phase resetting of the circadian clock mediated by the retinohypothalamic tract (RHT). Attempts to block or remove PACAP's contribution to clock-resetting have generated phenotypes that differ in their responses to light or glutamate. For example, previous studies of circadian behaviors found that period-maintenance and early-night phase delays are intact in PACAP-null mice, yet there is a consistent deficit in behavioral phase-resetting to light stimulation in the late night.

Disrupted-in-schizophrenia 1 functional polymorphisms and D /D receptor availability: A [ C]-(+)-PHNO imaging study.

Genes Brain Behav 2019 11 5;18(8):e12596. Epub 2019 Jul 5.

Psychiatric Imaging Group, Robert Steiner MRI Unit, MRC London Institute of Medical Sciences, Hammersmith Hospital, London, UK.

The disrupted-in-schizophrenia 1 (DISC1) protein has been implicated in a range of biological mechanisms underlying chronic mental disorders such as schizophrenia. Schizophrenia is associated with abnormal striatal dopamine signalling, and all antipsychotic drugs block striatal dopamine 2/3 receptors (D Rs). Importantly, the DISC1 protein directly interacts and forms a protein complex with the dopamine D receptor (D R) that inhibits agonist-induced D R internalisation. Read More

Sortilin gates neurotensin and BDNF signaling to control peripheral neuropathic pain.

Sci Adv 2019 06 19;5(6):eaav9946. Epub 2019 Jun 19.

The Lundbeck Foundation Research Center MIND, Department of Biomedicine, Aarhus University, Denmark.

Neuropathic pain is a major incurable clinical problem resulting from peripheral nerve trauma or disease. A central mechanism is the reduced expression of the potassium chloride cotransporter 2 (KCC2) in dorsal horn neurons induced by brain-derived neurotrophic factor (BDNF), causing neuronal disinhibition within spinal nociceptive pathways. Here, we demonstrate how neurotensin receptor 2 (NTSR2) signaling impairs BDNF-induced spinal KCC2 down-regulation, showing how these two pathways converge to control the abnormal sensory response following peripheral nerve injury.

Characterization of pathogenic monoclonal autoantibodies derived from muscle-specific kinase myasthenia gravis patients.

JCI Insight 2019 Jun 20;4(12). Epub 2019 Jun 20.

Department of Neurology and.

Myasthenia gravis (MG) is a chronic autoimmune disorder characterized by muscle weakness and caused by pathogenic autoantibodies that bind to membrane proteins at the neuromuscular junction. Most patients have autoantibodies against the acetylcholine receptor (AChR), but a subset of patients have autoantibodies against muscle-specific tyrosine kinase (MuSK) instead. MuSK is an essential component of the pathway responsible for synaptic differentiation, which is activated by nerve-released agrin. Read More

RhoA regulates translation of the Nogo-A decoy SPARC in white matter-invading glioblastomas.

Acta Neuropathol 2019 08 6;138(2):275-293. Epub 2019 May 6.

Schaller Research Group at the University of Heidelberg, German Cancer Research Center (DKFZ), Im Neuenheimer Feld 581, 69120, Heidelberg, Germany.

Glioblastomas strongly invade the brain by infiltrating into the white matter along myelinated nerve fiber tracts even though the myelin protein Nogo-A prevents cell migration by activating inhibitory RhoA signaling. The mechanisms behind this long-known phenomenon remained elusive so far, precluding a targeted therapeutic intervention. This study demonstrates that the prevalent activation of AKT in gliomas increases the ER protein-folding capacity and enables tumor cells to utilize a side effect of RhoA activation: the perturbation of the IRE1α-mediated decay of SPARC mRNA.

Institute of Cognitive Neuroscience, University College London, London, United Kingdom.

Measuring whole-brain functional connectivity patterns based on task-free ('resting-state') spontaneous fluctuations in the functional MRI (fMRI) signal is a standard approach to probing habitual brain states, independent of task-specific context. This view is supported by spatial correspondence between task- and rest-derived connectivity networks. Yet, it remains unclear whether intrinsic connectivity observed in a resting-state acquisition is persistent during task. Read More

Aphasia rehabilitation based on mirror neuron theory: a randomized-block-design study of neuropsychology and functional magnetic resonance imaging.

Neural Regen Res 2019 Jun;14(6):1004-1012

Department of Rehabilitation Medicine, The First Affiliated Hospital of Nanjing Medical University, Nanjing, Jiangsu Province, China.

When watching someone performs an action, mirror neurons are activated in a way that is very similar to the activation that occurs when actually performing that action. Previous single-sample case studies indicate that hand-action observation training may lead to activation and remodeling of mirror neuron systems, which include important language centers, and may improve language function in aphasia patients. In this randomized-block-design experiment, we recruited 24 aphasia patients from, Zhongda Hospital, Southeast University, China. Read More

Hydrogen sulfide downregulates colonic afferent sensitivity by a nitric oxide synthase-dependent mechanism in mice.

Neurogastroenterol Motil 2019 01 19;31(1):e13471. Epub 2018 Sep 19.

Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Shandong University Cheeloo Medical College, Shandong, China.

Background: The effect of hydrogen sulfide (H S) on visceral nociception is elusive. The conflicting evidence of its pro- and antinociceptive effects raises a series of questions with respect to the effect of H S on colonic afferent activity and the underlying mechanism, which was further elucidated in this study.

Methods: Colonic mesenteric afferent nerve spikes of normal male C57BL/6J mice, Cbs mice, and Wistar rats were recorded in vitro. Read More

[Clinical characteristic of factors and tools influencing the effectiveness and safety of local anesthesia in dentistry].

Stomatologiia (Mosk) 2018;97(4):77-81

North-Eastern federal university named after M.K. Ammosov, Yakutsk, Rossia.

Dental health is one of the most important signs of life quality and depends on the level of health care organization. Recently the clinical odontology is intensively developing, including local anesthesia where constant searching of effective remedies and methods of suppression and treatment of pain is carried out. At the same time carrying out adequate local anesthesia has important practical value that is to some extent bound to massive visits of the patients to the clinics. Read More

Urgent care peripheral nerve blocks for refractory trigeminal neuralgia.

Am J Emerg Med 2018 11 8;36(11):2058-2060. Epub 2018 Aug 8.

Department of Anesthesiology, New York-Presbyterian Hospital/Weill Cornell Medicine, 525 East 68th Street, Box 124, New York, NY 10065, United States of America.

Objective: After medication failure, patients with refractory trigeminal neuralgia (TGN) often present urgently and seek more potent or invasive therapies such as opioids or surgical options. Peripheral nerve blocks, safe and simple, may offer extended pain relief prior to opioid use or more invasive ganglion level procedures.

Methods: We report a retrospective case-series (urgent care, at a large urban medical center, over a 2 year period) of nine patients with intractable primary TGN who underwent peripheral trigeminal nerve blocks after failing conservative medical therapy. Read More

Ultrastructural basis of strong unitary inhibition in a binaural neuron.

J Physiol 2018 10 2;596(20):4969-4982. Epub 2018 Sep 2.

Laboratory of Synaptic Mechanisms, Brain Mind Institute, School of Life Science, École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland.

Key Points: Neurons of the lateral superior olive (LSO) in the brainstem receive powerful glycinergic inhibition that originates from the contralateral ear, and that plays an important role in sound localization. We investigated the ultrastructural basis for strong inhibition of LSO neurons using serial block face scanning electron microscopy. The soma and the proximal dendrite of an LSO neuron are surrounded by a high density of inhibitory axons, whereas excitatory axons are much sparser. Read More

Computed Tomography-Guided Superior Hypogastric Plexus Block for Secondary Dysmenorrhea in Perimenopausal Women.

Med Sci Monit 2018 Jul 24;24:5132-5138. Epub 2018 Jul 24.

The First Hospital of Jiaxing, Jiaxing, Zhejiang, China (mainland).

BACKGROUND Refractory abdominal pain during menstruation severely affects patients' quality of life and simultaneously places enormous psychological burdens on patients and their families. Several treatments for secondary dysmenorrhea are available; however, none can permanently treat all types of secondary dysmenorrhea. Since pain is transmitted by the nerves, we hypothesized that a neurolytic block could be used as a treatment for refractory abdominal pain during menstruation. Read More

Analgesia Nociception Index-guided intraoperative fentanyl consumption and postoperative analgesia in patients receiving scalp block versus incision-site infiltration for craniotomy.

Minerva Anestesiol 2018 12 9;84(12):1361-1368. Epub 2018 Jul 9.

Department of Neuroanaesthesia and Neurocritical Care, National Institute of Mental Health and Neurosciences, Bengaluru, India.

Background: Scalp block or local anesthetic infiltration for craniotomy blunts hemodynamic response to noxious stimuli, reduces opioid requirement and decreases postoperative pain. Analgesia Nociception Index (ANI) provides objective information about the magnitude of pain (rated from 0 to 100 with 0 indicating extreme nociception and 100 indicating absence of nociception) and adequacy of intra-operative analgesia. This study compared intra-operative fentanyl consumption guided by ANI and postoperative pain in patients who receive scalp block with those who receive incision-site local anesthetic infiltration for craniotomy.

Ultrasound-Guided Intervention for Treatment of Trigeminal Neuralgia: An Updated Review of Anatomy and Techniques.

Pain Res Manag 2018 2;2018:5480728. Epub 2018 Apr 2.

Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital Bei-Hu Branch, Taipei, Taiwan.

Orofacial myofascial pain is prevalent and most often results from entrapment of branches of the trigeminal nerves. It is challenging to inject branches of the trigeminal nerve, a large portion of which are shielded by the facial bones. Bony landmarks of the cranium serve as important guides for palpation-guided injections and can be delineated using ultrasound. Read More

Department of Psychiatry & Behavioral Sciences, Stanford University, 401 Quarry Rd, St 1356, Stanford, CA, 94305, USA.

Little is known about how our brains dynamically adapt for efficient functioning. Most previous work has focused on analyzing changes in co-fluctuations between a set of brain regions over several temporal segments of the data. We argue that by collapsing data in space or time, we stand to lose useful information about the brain's dynamical organization. Read More
