Coupling of autonomic and central events during sleep benefits declarative memory consolidation.

Neurobiol Learn Mem 2018 Dec 15. Epub 2018 Dec 15.

Department of Cognitive Sciences, University of California Irvine, Irvine, CA, USA.

While anatomical pathways between forebrain cognitive and brainstem autonomic nervous centers are well-defined, autonomic-central interactions during sleep and their contribution to waking performance are not understood. Here, we analyzed simultaneous central activity via electroencephalography (EEG) and autonomic heart beat-to-beat intervals (RR intervals) from electrocardiography (ECG) during wake and daytime sleep. We identified bursts of ECG activity that lasted 4-5 seconds and predominated in non-rapid-eye-movement sleep (NREM). Read More

An anatomical hypothesis: a "concentric-structured model" for the theoretical understanding of the surgical anatomy in the upper mediastinum required for esophagectomy with radical mediastinal lymph node dissection.

Dis Esophagus 2018 Dec 17. Epub 2018 Dec 17.

Department of Esophageal Surgery, National Cancer Center Hospital East, Kashiwa, Chiba, Japan.

Understanding the surgical anatomy is the key to reducing surgical invasiveness especially in the upper mediastinal dissection for esophageal cancer, which is supposed to have a significant impact on curability and morbidity. However, there is no theoretical recognition regarding the surgical anatomy required for esophagectomy, although the surgical anatomy in abdominal digestive surgery has been developed on the basis of embryological findings of intestinal rotation and fusion fascia. Therefore, we developed a hypothesis of a 'concentric-structured model' of the surgical anatomy in the upper mediastinum based on human embryonic development. Read More

Trait divergence, not plasticity, determines the success of a newly invasive plant.

Ann Bot 2018 Dec 15. Epub 2018 Dec 15.

Department of Biology, Portland State University, Portland, USA.

Background And Aims: Phenotypic plasticity and genetic differentiation both play important roles in the establishment and spread of species after extra-range dispersal; however, the adaptive potential of plasticity and genetic divergence in successful invasions remains unclear.

Methods: We measured six anatomical traits associated with drought tolerance in contrasting water environments for individuals from the invasive and native range of the bunchgrass Brachypodium sylvaticum. To represent sources contributing to admixed genotypes in the invasive range accurately, we used unique alleles to determine probabilities of genetic contribution, and utilized these as weights in our analyses.

Aggression in BALB/cJ mice is differentially predicted by the volumes of anterior and midcingulate cortex.

Brain Struct Funct 2018 Dec 18. Epub 2018 Dec 18.

Department of Cognitive Neuroscience, Donders Institute for Brain, Cognition and Behaviour​, Radboudumc, Kapittelweg 29, 6525 EN, Nijmegen, The Netherlands.

Anterior cingulate cortex (ACC) and midcingulate cortex (MCC) have been implicated in the regulation of aggressive behaviour. For instance, patients with conduct disorder (CD) show increased levels of aggression accompanied by changes in ACC and MCC volume. However, accounts of ACC/MCC changes in CD patients have been conflicting, likely due to the heterogeneity of the studied populations. Read More

Autonomic responses to blast overpressure can be elicited by exclusively exposing the ear in rats.

J Otol 2018 Jun 9;13(2):44-53. Epub 2018 Mar 9.

Department of Otolaryngology and Communicative Sciences, University of Mississippi Medical Center, Jackson, MS, USA.

Blast overpressure has become an increasing cause of brain injuries in both military and civilian populations. Though blast's direct effects on the cochlea and vestibular organs are active areas of study, little attention has been given to the ear's contribution to the overall spectrum of blast injury. Acute autonomic responses to blast exposure, including bradycardia and hypotension, can cause hypoxia and contribute to blast-induced neurotrauma. Read More

Institute of Pathology and Southwest Cancer Center, Key Laboratory of the Ministry of Education, Southwest Hospital, Army Medical University (Third Military Medical University), Chongqing, China.

Early invasive growth along specific anatomical structures, especially the white matter tract, is regarded as one of the main causes of poor therapeutic outcome of people with gliomas. We show that some glioma stem cells (GSCs) are preferentially located along white matter tracts, which exhibit a demyelinated phenotype, at the invasive frontier of glioma tissues. These GSCs are CD133Notch1, whereas the nerve fibers express the Notch ligand Jagged1. Read More

Following spinal cord injury, PDE4B drives an acute, local inflammatory response and a chronic, systemic response exacerbated by gut dysbiosis and endotoxemia.

Neurobiol Dis 2018 Dec 14. Epub 2018 Dec 14.

Kentucky Spinal Cord Injury Research Center, University of Louisville, School of Medicine, 511 S. Floyd St., MDR 616, Louisville, KY 40202, USA; Department of Anatomical Science & Neurobiology, University of Louisville, School of Medicine, 511 S. Floyd St., MDR 616, Louisville, KY 40202, USA.

Emerging evidence links changes in the gut microbiome and intestinal barrier function to alterations in CNS function. We examined the role of endotoxin-responsive, cAMP-specific, Pde4 subfamily b (Pde4b) enzyme in gut dysbiosis induced neuro-inflammation and white matter loss following spinal cord injury (SCI). Using a thoracic contusion model in C57Bl/6 wild type female mice, SCI led to significant shifts in the gut bacterial community including an increase in the phylum Proteobacteria, which consists of endotoxin-harboring, gram-negative bacteria.

Pharmacol Ther 2018 Dec 14. Epub 2018 Dec 14.

Duke Brain Tumor Immunotherapy Program, Department of Neurosurgery, Duke University Medical Center, Durham, NC 27710., United States; The Preston Robert Tisch Brain Tumor Center, Duke University Medical Center, Durham, NC 27710., United States; Department of Neurosurgery, Duke University School of Medicine, Durham, NC 27710., United States; Department of Biomedical Engineering, Pratt School of Engineering, Duke University, Durham, NC 27710, United States; Department of Pathology, Duke University School of Medicine, Durham, NC 27710., United States. Electronic address:

Several Phase II and III clinical trials have demonstrated that immunotherapy can induce objective responses in otherwise refractory malignancies in tumors outside the central nervous system. In large part, effector T cells mediate much of the antitumor efficacy in these trials, and potent antitumor T cells can be generated through vaccination, immune checkpoint blockade, adoptive transfer, and genetic manipulation. However, activated T cells must still traffic to, infiltrate, and persist within tumor in order to mediate tumor lysis. Read More
