A case of severe hemorrhagic shock caused by traumatic avulsion of uterine fibroid.

Case Presentation: A 40-year-old woman was injured in a motor vehicle accident. Physician-staffed helicopter emergency medical service (HEMS) was dispatched, and after the HEMS physician performed thoracostomy and tracheal intubation to relieve the tension pneumothorax and hemorrhagic shock, her carotid artery became unpalpable. The physician then decided to perform prehospital resuscitative thoracotomy.

Therapeutic strategies for pseudoaneurysm following blunt liver and spleen injuries: A multicenter cohort study in the pediatric population.

Background: Little guidance exists for the treatment of pseudoaneurysm (PA) following pediatric blunt liver and/or spleen injuries (BLSIs). We aimed to describe the incidence of delayed PA development and the subsequent clinical course of PA in pediatric BLSIs.

Methods: This multicenter retrospective cohort study from Japan included pediatric patients (16 years and younger) who sustained BLSIs from 2008 to 2019.

Emergent surgery for cardiac herniation coexisting with complex blunt cardiac injury: A case report.

A 38-year-old man was pressed on his trunk by a heavy object weighing about 100 kg. The patient was in shock status on arrival to the hospital. Circular collapse progressed rapidly during contrast computed tomography (CT) scanning.

Current status and management of pancreatic trauma with main pancreatic duct injury: A multicenter nationwide survey in Japan.

Background: Pancreatic trauma is reportedly associated with high morbidity and mortality. Main pancreatic duct (MPD) injury is critical for treatment.

Methods: As a study project of the Japanese Society for Abdominal Emergency Medicine (JSAEM), we collected the data of 163 patients with pancreatic trauma who were diagnosed and treated at JSAEM board-certified hospitals from 2006 to 2016.

MicroRNA expression profiles of neuron-derived extracellular vesicles in plasma from patients with amyotrophic lateral sclerosis.

Circulating microRNAs (miRNAs) in peripheral blood have been extensively investigated as biomarkers for early diagnosis and monitoring of disease progression. However, their cellular origin as well as their link to the pathophysiology, especially neurodegenerative disease, remains largely unknown. In the present study, we isolated neuron-derived extracellular vesicles (EVs) in plasma by immunoaffinity purification and comprehensively analyzed their miRNA expression profiles using microarray.

Advanced cadaver-based educational seminar for trauma surgery using saturated salt solution-embalmed cadavers.

Aim: Senior surgeons in Japan who participated in "cadaver-based educational seminar for trauma surgery (CESTS)" subsequently stated their interest in seminars for more difficult procedures. Therefore, we held a 1-day advanced-CESTS with saturated salt solution (SSS)-embalmed cadavers and assessed its effectiveness for surgical skills training (SST).

Methods: Data were collected from three seminars carried out from September 2015 to January 2018, including a 10-point self-assessment of confidence levels (SACL) questionnaire on nine advanced surgical skills, and evaluation of seminar content before, just after, and half a year after the seminar.

The Pedicled Omental Flap Technique for Treating Extensive Defects or Soft-Tissue Infection of the Pelvic Area: A Report of 2 Cases.

Severe trauma injuries, such as open pelvic fractures and degloving injuries, have recently become salvageable. However, extensive soft-tissue defects often remain and can lead to disuse atrophy of the extremities, prolonged hospital stays, and numerous other problems. Such injuries can be easily and effectively treated by a general trauma surgeon performing the pedicled omental flap technique.

Cuprizone short-term exposure: astrocytic IL-6 activation and behavioral changes relevant to psychosis.

A growing body of evidence suggests the involvement of inflammatory processes in the pathophysiology of schizophrenia. Four- to 8-week exposure to cuprizone, a copper chelator, causes robust demyelination and has been used to build a model for multiple sclerosis. In contrast, we report here the effects of 1-week cuprizone exposure in mice.

Hesr1 knockout mice exhibit behavioral alterations through the dopaminergic nervous system.

The basic helix-loop-helix (bHLH) transcriptional factor Hesr1 gene (hairy and enhancer of split-related 1, also called Hey1/HRT1/CHF2/HERP2) has been identified and characterized as a member of the subfamily of hairy/Enhancer of split, and shown to be involved in cardiovascular and neural development. We report that HESR1 binds directly to a part of the 3' non-coding region of the human dopamine transporter (DAT1) gene and represses the endogenous DAT1 gene in HEK293 cells. To investigate functions of the HESR1 gene in the dopaminergic nervous system in vivo, we analyzed the expressions of dopamine-related genes in the postnatal day 0 whole brains of Hesr1 knockout mice by real-time RT-PCR analysis.

Effect of a novel potential atypical antipsychotic drug, Y-931, in producing dystonia in cebus monkeys.

The effect of Y-931 (8-fluoro-12-(4-methylpiperazin-1-yl)-6H-[1]benzothieno[2,3-b][1,5]benzodiazepine maleate), a novel potential atypical antipsychotic candidate, in producing dystonia in Cebus monkeys was investigated. Y-931 induced relatively weak dystonia in several observation periods at doses greater than 0.1 mg/kg, i.

Neuropharmacological profile of a novel potential atypical antipsychotic drug Y-931 (8-fluoro-12-(4-methylpiperazin-1-yl)- 6H-[1]benzothieno[2,3-b][1,5] benzodiazepine maleate).

The neuropharmacological profile of Y-931, 8-fluoro-12- (4-methylpiperazin-1-yl)- 6H-[1]benzothieno [2,3-b][1,5]benzodiazepine maleate, was investigated in comparison with those of typical and claimed atypical antipsychotic drugs. Similar to clozapine and olanzapine, Y-931 interacted with multiple neurotransmitter receptors such as dopaminergic, serotonergic, alpha-adrenergic, muscarinic and histaminergic receptors. Y-931, as well as the other antipsychotics, was active in a dose-dependent manner in established tests which are indicative of potential antipsychotic activity such as inhibition of apomorphine-induced hyperactivity and suppression of conditioned avoidance responses, however, only Y-931 and clozapine were devoid of cataleptogenic potential.
