Astrocyte progenitor transplantation promotes regeneration of bulbospinal respiratory axons, recovery of diaphragm function, and a reduced macrophage response following cervical spinal cord injury.

Glia 2018 Dec 11. Epub 2018 Dec 11.

Department of Neuroscience, Vickie and Jack Farber Institute for Neuroscience, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, Pennsylvania.

Stem/progenitor cell transplantation delivery of astrocytes is a potentially powerful strategy for spinal cord injury (SCI). Axon extension into SCI lesions that occur spontaneously or in response to experimental manipulations is often observed along endogenous astrocyte "bridges," suggesting that augmenting this response via astrocyte lineage transplantation can enhance axon regrowth. Given the importance of respiratory dysfunction post-SCI, we transplanted glial-restricted precursors (GRPs)-a class of lineage-restricted astrocyte progenitors-into the C2 hemisection model and evaluated effects on diaphragm function and the growth response of descending rostral ventral respiratory group (rVRG) axons that innervate phrenic motor neurons (PhMNs).

Sound field reconstruction using multipole equivalent source model with un-fixed source locations.

J Acoust Soc Am 2018 Nov;144(5):2674

Ray W. Herrick Laboratories, Purdue University, 177 South Russell Street, West Lafayette, Indiana 47907-2099, USA.

The equivalent source methods (ESM) that have been developed to this point can generally be classified into two categories: one in which a relatively large number of lower order sources are fixed at various locations, and one in which a series of higher order sources are fixed at one location. The present work started with a model in the latter category, but the individual sources were then allowed to move separately to locations which were determined by using a nonlinear optimization procedure based on the measured sound field data. To test this approach, experiments were conducted using a small loudspeaker cabinet; measurements were made using an array of microphones on all sides of the loudspeaker. Read More

Diaphragm-protective mechanical ventilation.

Curr Opin Crit Care 2018 Dec 5. Epub 2018 Dec 5.

Interdepartmental Division of Critical Care Medicine, University of Toronto.

Purpose Of Review: Diaphragm dysfunction is common in mechanically ventilated patients and predisposes them to prolonged ventilator dependence and poor clinical outcomes. Mechanical ventilation is a major cause of diaphragm dysfunction in these patients, raising the possibility that diaphragm dysfunction might be prevented if mechanical ventilation can be optimized to avoid diaphragm injury - a concept referred to as diaphragm-protective ventilation. This review surveys the evidence supporting the concept of diaphragm-protective ventilation and introduces potential routes and challenges to pursuing this strategy. Read More

Muscle specific kinase (MuSK) activation preserves neuromuscular junctions in the diaphragm but is not sufficient to provide a functional benefit in the SOD1 mouse model of ALS.

Neurobiol Dis 2018 Dec 4. Epub 2018 Dec 4.

Departments of Neuroscience, Genentech, South San Francisco, CA, USA. Electronic address:

Amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting motor neurons, is characterized by rapid decline of motor function and ultimately respiratory failure. As motor neuron death occurs late in the disease, therapeutics that prevent the initial disassembly of the neuromuscular junction may offer optimal functional benefit and delay disease progression. To test this hypothesis, we treated the SOD1 mouse model of ALS with an agonist antibody to muscle specific kinase (MuSK), a receptor tyrosine kinase required for the formation and maintenance of the neuromuscular junction.

Diaphragmatic dysfunction.

Pulmonology 2018 Nov 30. Epub 2018 Nov 30.

Pneumology Service, University Hospital Complex of Santiago, Santiago de Compostela, Spain; Interdisciplinary Research Group in Pulmonology, Institute of Sanitary Research of Santiago de Compostela (IDIS), Santiago de Compostela, Spain.

The diaphragm is the main breathing muscle and contraction of the diaphragm is vital for ventilation so any disease that interferes with diaphragmatic innervation, contractile muscle function, or mechanical coupling to the chest wall can cause diaphragm dysfunction. Diaphragm dysfunction is associated with dyspnoea, intolerance to exercise, sleep disturbances, hypersomnia, with a potential impact on survival. Diagnosis of diaphragm dysfunction is based on static and dynamic imaging tests (especially ultrasound) and pulmonary function and phrenic nerve stimulation tests. Read More

Molecular mechanism of fusion pore formation driven by the neuronal SNARE complex.

Proc Natl Acad Sci U S A 2018 Dec 27;115(50):12751-12756. Epub 2018 Nov 27.

Laboratory for Nanoscale Cell Biology, Max Planck Institute for Biophysical Chemistry, 37077 Göttingen, Germany.

Release of neurotransmitters from synaptic vesicles begins with a narrow fusion pore, the structure of which remains unresolved. To obtain a structural model of the fusion pore, we performed coarse-grained molecular dynamics simulations of fusion between a nanodisc and a planar bilayer bridged by four partially unzipped SNARE complexes. The simulations revealed that zipping of SNARE complexes pulls the polar C-terminal residues of the synaptobrevin 2 and syntaxin 1A transmembrane domains to form a hydrophilic core between the two distal leaflets, inducing fusion pore formation.

Chilaiditi's sign, a cause of pseudo-pneumoperitoneum: A case report.

SAGE Open Med Case Rep 2018 19;6:2050313X18812213. Epub 2018 Nov 19.

Hospital Segamat, Segamat, Malaysia.

The differentiation between a pseudo-pneumoperitoneum and true pneumoperitoneum on an initial chest radiograph is challenging but essential to clinical practice. The former is managed conservatively whereas the latter may require surgical intervention. Chilaiditi's sign describes a rare incidental radiological finding of gas filled bowel interpositioned between the right hemi-diaphragm and the liver, which is visible on a plain abdominal or chest radiograph.

[Descemet membrane endothelial keratoplasty in complex eyes].

Ophthalmologe 2018 Nov 26. Epub 2018 Nov 26.

Zentrum für Augenheilkunde, Universität zu Köln, Kerpenerstr. 62, 50924, Köln, Deutschland.

Background: Descemet membrane endothelial keratoplasty (DMEK) has become the standard surgical treatment for Fuchs' endothelial corneal dystrophy (FECD) in Germany. In addition to classical FECD, there are endothelial disorders amenable to DMEK associated with complex changes in the anterior segment of the eye, such as anterior synechia of the iris, larger iris defects, after glaucoma surgery, after vitrectomy and after trauma.

Objective: This article provides an overview of the possibilities to treat patients with complex anterior segment situations in the presence of corneal endothelial decompensation with DMEK. Read More

Knowledge and use of family planning among men in rural Uganda.

BMC Public Health 2018 Nov 26;18(1):1294. Epub 2018 Nov 26.

African Community Center for Social Sustainability (ACCESS), Nakaseke, Uganda.

Background: Unmet need for family planning exceeds 33% in Uganda. One approach to decreasing unmet need is promoting male involvement in family planning. Male disapproval of use of family planning by their female partners and misconceptions about side effects are barriers to family planning globally and in Uganda in particular. Read More

Adjuvant Lymphatic Osteopathic Manipulative Treatment in Patients With Lower-Extremity Ulcers: Effects on Wound Healing and Edema.

J Am Osteopath Assoc 2018 Dec;118(12):798-805

Context: In 2012, the US wound registry estimated that the cost of managing chronic wounds in the United States exceeded $50 billion. A large percentage of these wounds are venous stasis ulcers of the lower extremity. Evidence suggests that adjuvant osteopathic manipulative treatment (OMT) may provide a benefit by reducing edema and subsequent healing times in venous stasis ulcers of the lower extremity.

Detection of anti-viral antibodies from meat juice of wild boars.

J Vet Med Sci 2018 Nov 23. Epub 2018 Nov 23.

Laboratory of Veterinary Microbiology, Joint Faculty of Veterinary Medicine, Yamaguchi University.

Wild boars are a reservoir for many zoonotic pathogens and a good sentinel for surveillance of zoonotic viral infections, but collection of serum samples from wild boars in the field is sometimes difficult and requires special equipment and techniques. In this study, ELISA using meat juices extracted from the heart and diaphragm of wild boars, instead of serum samples, was performed to detect antibodies against zoonotic pathogens, Japanese encephalitis virus and hepatitis E virus. The results of ELISA using meat juice samples were significantly correlated with those using serum samples and meat juice contained one-fifth the antibodies of serum samples. Read More
