INTRODUCTION: Gastrointestinal stromal tumors (GISTs) are clinically asymptomatic until they reach a significant size; therefore, GISTs that are 2cm or less are typically asymptomatic. Patients with symptomatic GISTs typically present with abdominal pain, gastrointestinal bleeding, or a palpable mass but rarely present with hemoperitoneum. PRESENTATION OF CASE: A 72-year-old Japanese man presented to us with acute onset abdominal pain. Physical examination showed peritoneal irritation in the lower abdomen...

After sawing in the intraoral vertical ramus osteotomy, in the case of an incomplete amputation, the proximal segment is split using the osteotome. Unfortunately, in this case, the proximal segment was accidentally fractured. The operation was completed without performing any other fixation. Postoperatively intermaxillary fixation was performed and kept for a week, followed by physical therapy, which was initiated immediately after. The patient was closely observed for 6 months. No abnormal findings were detected clinically, and the union of bone was verified...

Atomic chains are perfect systems for getting fundamental insights into the electron dynamics and coupling between the electronic and ionic degrees of freedom in one dimensional metals. Depending on the band filling, they can exhibit Peierls instabilities (or charge density waves), where equally spaced chain of atoms with partially filled band is inherently unstable, exhibiting spontaneous distortion of the lattice that further leads to metal-insulator transition in the system. Here, using high-resolution scanning transmission electron microscopy, we directly image the atomic structures of a chain of iodine atoms confined inside carbon nanotubes...

A 3.5-y-old Whippet mixed-breed dog was presented with a history of respiratory distress, exercise intolerance, and generalized demodicosis. Hematologic alterations included marked leukocytosis and neutrophilia. Radiographic examination showed a diffuse interstitial and mild peripheral alveolar lung pattern and pneumomediastinum. Because the cytologic examination of the bronchoalveolar aspirate was not diagnostic and a persistent perforation of the upper respiratory tract could not be ruled out, the dog was submitted to thoracoscopy, and subsequently the left cranial lung lobe as well as mediastinal and sternal lymph nodes were resected...

More than half of all spinal cord injuries (SCIs) occur at the cervical level, often resulting in impaired respiration. Despite this devastating outcome, there is substantial evidence for endogenous neuroplasticity after cervical SCI. Spinal interneurons are widely recognized as being an essential anatomical component of this plasticity by contributing to novel neuronal pathways that can result in functional improvement. The identity of spinal interneurons involved with respiratory plasticity post-SCI, however, has remained largely unknown...

A M Eriksson, A Vikström
Recent advances have attracted attention to nonstandard Josephson junctions in which a supercurrent can flow despite zero phase difference between the constituent superconducting leads. Here, we propose a zero-phase-difference nanoelectromechanical junction which, in contrast to other considered systems, exhibits symmetry between leftward and rightward tunneling through the junction. We show that a supercurrent is, nevertheless, possible as a result of spontaneous symmetry breaking. In the suggested junction, the supercurrent is mediated by tunneling via a superconducting Cooper-pair box on a mechanical resonator...

A hybrid vector of adeno-associated virus and phage (termed AAVP) has been introduced as a platform for systemic ligand-directed delivery of transgenes to tumors over the past decade. A series of studies have evaluated the AAVP platform for potential theranostic or purely therapeutic applications in several tumor models. Sufficient ligand-directed tumor targeting consistently resulted in specific molecular-genetic imaging and/or anti-tumor responses to 'suicide' transgene delivery. However, efforts to optimize transduction efficiency are still ongoing...

The increasing demand for rare earth (RE) elements in advanced materials for permanent magnets, rechargeable batteries, catalysts and lamp phosphors necessitates environmentally friendly approaches for their recovery and separation. Here, we propose a mineralization concept for direct extraction of RE ions with Lamp (lanthanide ion mineralization peptide). In aqueous solution containing various metal ions, Lamp promotes the generation of RE hydroxide species with which it binds to form hydrophobic complexes that accumulate spontaneously as insoluble precipitates, even under physiological conditions (pH ∼6...

Ventricular septal defects are one of the most common congenital cardiac malformations in animals, and most often affect the membranous portion of the septum. These defects may rarely close spontaneously. An adult male black-tailed prairie dog ( Cynomys ludovicianus) had a smooth shiny botryoid red mass arising from the area of the septal cusp of the right atrioventricular (tricuspid) valve and membranous interventricular septum, and bulging into the right ventricular lumen. Histology and special staining demonstrated a membranous ventricular septal defect closed by the adherence of the septal cusp of the tricuspid valve to the muscular septum (so-called membranous ventricular septal aneurysm or aneurysm of the [peri]membranous ventricular septum)...

A 27-year-old male chimpanzee (Pan troglodytes verus) developed signs of thrombotic thrombocytopenic purpura (TTP). ADAMTS13 deficiency appeared to be the cause of disease. After treatment with high-dose prednisone, haematological values and clinical signs recovered. This is the first description of spontaneous TTP associated with ADAMTS13 deficiency in a non-human primate.

A novel and simple strategy is developed to construct ultralight and 3D pure carbon nanotube (CNT) aerogels by the spontaneous expansion of superaligned CNT films soaked in a piranha (mixed H2 SO4 and H2 O2 ) solution, followed by cryodesiccation. The macroscopic CNT aerogels have an extremely low apparent density (0.12 mg cm(-3) ), ultrahigh porosity (99.95%), high specific surface area (298 m(2) g(-1) ), and a hierarchical cellular structure with giant and ultrathin CNT sheets as cell walls. The pure CNT aerogels show high adsorption abilities for various kinds of solvents, and have great potential in widespread applications such as energy storage, catalysis, and bioengineering...

INTRODUCTION AND HYPOTHESIS: Catheterization type among women laboring with epidural analgesia who develop bladder retention has been reported to affect labor duration and mode of delivery. We aimed to compare the effect of continuous bladder catheterization (CC) with that of intermittent bladder catheterization (IC) on the duration of the second stage of labor. METHODS: In a randomized trial, term nulliparous women with singleton gestation who requested epidural analgesia and were unable to void spontaneously were eligible and randomized to either CC or IC...

Simple ML2 [M = Fe(ii), Co(ii), Ni(ii)] complexes obtained from a perfluoroalkylamide derivative of 4-aminophenyl-2,2',6,2'-terpyridine spontaneously, yet anion selectively, self-assemble into gels, which manifest an unprecedented rapid gel strength recovery, viz. self-healing, and thermal rearrangement in aqueous dimethyl sulfoxide. The key factor for gelation and rheological properties emerges from the fluorine-fluorine interactions between the perfluorinated chains, as the corresponding hydrocarbon derivative did not form metallogels...

BACKGROUND: Acute kidney injury (AKI) occurs in more than half critically ill patients admitted in intensive care units (ICU) and increases the mortality risk. The main cause of AKI in ICU is sepsis. AKI severity and other related variables such as recurrence of AKI episodes may influence mortality risk. While AKI recurrence after hospital discharge has been recently related to an increased risk of mortality, little is known about the rate and consequences of AKI recurrence during the ICU stay...

BACKGROUND: Intracranial hemorrhage (ICH) is a recognized complication of adults treated with extracorporeal membrane oxygenation (ECMO) and is associated with increased morbidity and mortality. However, the predictors of ICH in this patient category are poorly understood. The purpose of this study was to identify predictors of ICH in ECMO-treated adult patients. METHODS: We conducted a retrospective review of adult patients (≥18 years) treated with ECMO at the Karolinska University Hospital (Stockholm, Sweden) between September 2005 and June 2016, excluding patients with ICH upon admission or those who were treated with ECMO for less than 12 h...

BACKGROUND: The current EAACI/GA(2)LEN/EDF/WAO guideline for urticaria provide specific recommendations for the diagnostic workup and treatment of patients with chronic spontaneous urticaria (CsU). This study explored if physicians in Ecuador know these recommendations and implement them in their actual clinical practice for CsU. METHODS: We investigated physicians who treat CsU patients in a cross-sectional study using a standardized questionnaire. Descriptive statistics were employed, adjusted logistic regression was performed to assess the link of guideline knowledge and use of therapy...

Feeding jejunostomy (FJ) is a commonly done surgical procedure for enteral nutrition. Intussusception is one of the rare complications of FJ. Clinical presentation may be similar to other causes of small bowel obstruction. Intussusception should be suspected if a patient with jejunostomy tube develops upper gastrointestinal obstructive symptoms, which are relieved by nasogastric tube drainage. CT or ultrasonography (USG) can help to confirm the diagnosis. It can be relieved spontaneously or sometimes requires laparotomy...
