Versatile functionalization of Bifidobacteria-derived extracellular vesicles using amino acid metabolic labeling and click chemistry for immunotherapy.

Extracellular vesicles (EVs) are nanoparticles secreted by various organisms. Methods for modifying EVs functionally have garnered attention for developing EV-based therapeutic systems. However, most technologies used to integrate these functions are limited to mammalian-derived EVs and a promising modification method for bacteria-derived EVs has not yet been developed.

Analgesic efficacy of modified thoracoabdominal nerves block through the perichondrial approach in laparoscopic cholecystectomy: A retrospective study with propensity analysis.

Modified thoracoabdominal nerves block through the perichondral approach (M-TAPA) was recently reported to provide broad analgesia with only a single injection of local anesthetics (LA) on each side. However, the effectiveness of M-TAPA in laparoscopic cholecystectomy (LC) is not often reported. We retrospectively evaluated the analgesic efficacy of M-TAPA in patients who underwent LC and compared it with conventional LA infiltration (LAI) by calculating the propensity score.

Dermal macrophages set pain sensitivity by modulating the amount of tissue NGF through an SNX25-Nrf2 pathway.

Cross-talk between peripheral neurons and immune cells is important in pain sensation. We identified Snx25 as a pain-modulating gene in a transgenic mouse line with reduced pain sensitivity. Conditional deletion of Snx25 in monocytes and macrophages, but not in peripheral sensory neurons, in mice (Snx25 mice) reduced pain responses in both normal and neuropathic conditions.

Synapsin-Promoted Caveolin-1 Overexpression Maintains Mitochondrial Morphology and Function in PSAPP Alzheimer's Disease Mice.

Mitochondrial dysfunction plays a pivotal role in the Alzheimer's Disease (AD) pathology. Disrupted mitochondrial dynamics (i.e.

NGF and BDNF expression in mouse DRG after spared nerve injury.

Neuropathic pain is initiated by a primary lesion in the peripheral nervous system and spoils quality of life. Neurotrophins play important roles in the development and transmission of neuropathic pain. There are conflicting reports that the dorsal root ganglion (DRG) in an injured nerve contribute to neuropathic pain, whereas several studies have highlighted the important contribution of the DRG in a non-injured nerve.

Olig2-Lineage Astrocytes: A Distinct Subtype of Astrocytes That Differs from GFAP Astrocytes.

Astrocytes are the most abundant glia cell type in the central nervous system (CNS), and are known to constitute heterogeneous populations that differ in their morphology, gene expression and function. Although glial fibrillary acidic protein (GFAP) is the cardinal cytological marker of CNS astrocytes, GFAP-negative astrocytes can easily be found in the adult CNS. Astrocytes are also allocated to spatially distinct regional domains during development.

Voluntary Exercise Induces Astrocytic Structural Plasticity in the Globus Pallidus.

Changes in astrocyte morphology are primarily attributed to the fine processes where intimate connections with neurons form the tripartite synapse and participate in neurotransmission. Recent evidence has shown that neurotransmission induces dynamic synaptic remodeling, suggesting that astrocytic fine processes may adapt their morphologies to the activity in their environment. To illustrate such a neuron-glia relationship in morphological detail, we employed a double transgenic Olig2(CreER/WT); ROSA26-GAP43-EGFP mice, in which Olig2-lineage cells can be visualized and traced with membrane-targeted GFP.

Highly spectral efficient networks based on grouped optical path routing.

In order to mitigate the signal spectrum narrowing caused by optical filtering at nodes, an adequate guard band is needed between optical channels, which degrades the frequency utilization of optical fibers. In this study, we propose a grouped routing based network architecture that minimizes spectrum narrowing while greatly improving spectral efficiency. Coarse granular routing at GRE (grouped routing entity) level is employed at each ROADM node, but fine granular add/drop is adopted to retain high frequency utilization.

[Comparison of Sedative and Analgesic Requirements in Children with and without Down Syndrome following Pediatric Cardiac Surgery].

Background: Conflicting results have been reported on postoperative analgesia in pediatric patients with Down syndrome. We compared sedative and analgesic requirements following cardiac surgery between pediatric patients with and without Down syndrome.

Methods: Patients who underwent atrial septal defect closure, ventricular septal defect closure and repair of atrioventricular septal defect at the age between one month and 24 months in our institution for 2 years from 2011 to 2012 were recruited into the study.

Hedgehog Signaling Modulates the Release of Gliotransmitters from Cultured Cerebellar Astrocytes.

Sonic hedgehog (Shh), a member of the Hedgehog (Hh) family, plays essential roles in the development of the central nervous system. Recent studies suggest that the Hh signaling pathway also functions in mature astrocytes under physiological conditions. We first examined the expression of genes encoding Hh signaling molecules in the adult mouse cerebellum by in situ hybridization histochemistry.

[Spontaneous Respiration Technique for Pediatric Microlaryngeal Surgery without Endotracheal Intubation].

We report the anesthetic management of microlaryngeal surgery in children using tubeless total intravenous anesthesia (TIVA) without endotracheal intubation under spontaneous breathing. In 9 patients (median age : 4.9 yr.

[Outcome of the Pediatric Patients Who Required Repeated Cardiopulmonary Bypass during the Repair of Congenital Heart Disease].

Background: We occasionally encounter clinical deterioration after discontinuation of cardiopulmonary bypass (CPB) and are forced to reinstitute CPB during cardiac surgery. Some reports describe such cases occurring in adults, but few in infants and children. We retrospectively investigated the causes and outcomes of children requiring repeated CPB during the repair of congenital heart anomalies.

[Perioperative fibrinogen concentrations in cardiac surgery with cardiopulmonary bypass].

Background: Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) need many blood products due to deficiency of coagulation factors. Blood transfusion therapy in patients with excessive bleeding after CPB is generally empiric. We checked and studied the fibrinogen concentration and transfusion, as well as bleeding amount in the perioperative period.

Dietary vitamin E deficiency increases anxiety-like behavior in juvenile and adult rats.

Vitamin E deficiency from birth or infancy has recently been found to increase anxiety-like behavior in rodents. The present study was undertaken to elucidate the effect of dietary vitamin E deficiency on anxiety in adult rats in comparison with juvenile rats. Male Wistar rats, 3 or 10 weeks old, were divided into two groups and fed a control or vitamin E-deficient diet for 4 weeks.

The impact of postoperative intensive care on outcomes in elective neurosurgical patients in good physical condition: a single centre propensity case-matched study.

Purpose: In the last three years, all elective neurosurgical cases were performed by a single surgeon at Nara Medical University. For the last year and a half, all patients were transferred to a newly created neurosurgical intensive care unit. The purpose of this study was to evaluate the impact of admission to an intensive care unit after elective neurosurgery.

[Patient scheduled for ligation of the contralateral internal jugular vein and its reconstruction following unilateral radical neck dissection].

A 76-year-old man who had previously undergone unilateral radical neck dissection (RND) was scheduled for contralateral radical neck dissection and reconstruction of the internal jugular vein (IJV) with the saphenous vein due to local recurrence of thyroid carcinoma infiltrating the IJV Reconstruction of the IJV was not necessary, however, because the preserved IJV was large enough to drain venous return after partial resection of the tumor-infiltrated part of the IJV. Reports of anesthetic management for bilateral RND are very rare. In this report, we discussed anesthetic management of bilateral RND including physiological changes and complications after bilateral IJV ligation and monitoring methods for disturbances of cerebral venous circulation.
