We report herein cathode configurations alternative to the most diffused ones for application in lithium-oxygen batteries using an ionic liquid-based electrolyte. The electrodes employ high surface area conductive carbon as the reaction host and polytetrafluoroethylene as the binding agent to enhance ORR/OER reversibility. Roll-pressed, self-standing electrodes (SSEs) and thinner, spray deposited electrodes (SDEs) are characterized in lithium-oxygen cells using an ionic liquid (IL) based electrolyte formed by mixing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt in N,N-diethyl-N-(2-methoxyethyl)-N-methylammonium bis(trifluoromethanesulfonyl)imide (DEMETFSI)...

INTRODUCTION: Contamination of the preservation solution may contribute to septic complications that can occur after transplantation and cause higher morbidity and mortality among recipients. The aim of this study was to determine potential donor-related predictors of positive microbiological findings in the preservation solution. DESIGN: We retrospectively studied 16 donor parameters on data from our center for microbiological findings in the preservation solution used in solid-organ recovery...

Introduction: Patients with metabolic syndrome (MetS) may have lower 25-hydroxyvitamin D (25(OH)VitD) serum levels compared with non-MetS individuals. Vitamin D (VitD) deficiency is associated with various cardiovascular disease (CVD) risk factors. Yet, the effect of VitD supplementation on MetS remains uncertain. Our aim was to examine the effect of VitD supplementation on CVD risk factors in MetS subjects. Material and methods: This pilot study had a PROBE (prospective, randomised, open-label, blinded end-point) design...

Antibiotics are the first line of treatment against infections and have contributed immensely to reduce the morbidity and mortality rates. Recently, extensive use of antibiotics has led to alterations of the gut microbiome, predisposition to various diseases and most importantly, increase in the emergence of antibiotic-resistant bacteria, which poses a major threat to global public health. Another major issue faced worldwide due to unregulated use of antibiotics in children as well as in adults is the influence of metabolism and body weight homeostasis, leading to obesity...

We studied the insecticidal activity of different concentrations of very high quality natural zeolites (zeolitic rock containing 92 wt% clinoptilolite) applied on dry beans. The test species was adult bean weevils Acanthoscelides obtectus (Say; Coleoptera: Bruchidae), and the variables included different temperatures and humidity regimes. At certain natural zeolite concentrations the adult mortality approached 100% within the first day of exposure. The lethal natural zeolite concentration for 50% adult mortality (LD50) was 1...

Color-selective absorption of light is a very significant operation used in numerous applications, from photonic sensing and switching to optical signal modulation and energy harnessing. We demonstrate angle-insensitive and polarization-independent absorption by thin bilayers comprising ordinary bulk media: dielectrics, semiconductors, and metals. Several highly efficient designs for each color of the visible spectrum are reported, and their internal fields' distributions reveal the resonance mechanism of absorption...

Gastric cancer remains a considerable health burden throughout the world. The Cancer Genome Atlas (TCGA) analysis has recently unveiled 4 genotypes of gastric cancer with data not ready to change treatment strategy yet. A multimodality approach to therapy is the cornerstone of screening, diagnosing, staging, treating and supporting patients with gastric cancer. The evidence-based approach to localized gastric cancer (>cT1b) is to use an either preoperative or postoperative strategy to maximize the benefit of surgery...

PURPOSE: To describe planning and a technique for fenestrated endovascular repair of a large Crawford type IV thoracoabdominal aortic aneurysm after previous 2-fenestration endovascular aneurysm repair (FEVAR). TECHNIQUE: The first FEVAR procedure performed at another center implanted a standard Zenith device with 2 fenestrations and 1 scallop for a juxtarenal abdominal aortic aneurysm. The diameter of the Crawford type IV thoracoabdominal aortic aneurysm had progressed from 68 to 75 mm within a year after the FEVAR...

There is robust evidence from epidemiological and clinical studies showing that elevated heart rate (HR) constitutes a powerful predictor of morbidity and mortality in patients with hypertension, underlining the significance of HR measurement in them. Autonomous nervous system dysfunction and atherosclerosis are important features in the pathogenesis of the untoward events. However, the relationship between HR and blood pressure (BP) is complex and differs depending on the type of BP measurement which is considered...

Background -Transforming Growth Factor (TGF)-βs regulate a wide range of cellular responses by activating Smad-dependent and Smad-independent cascades. In the infarcted heart, Smad3 signaling is activated in both cardiomyocytes and interstitial cells. We hypothesized that cell-specific actions of Smad3 regulate repair and remodeling in the infarcted myocardium. Methods -In order to dissect cell-specific Smad3 actions in myocardial infarction, we generated mice with Smad3 loss in activated fibroblasts, or in cardiomyocytes...

"Complex suicide" is a term referring to the suicidal pattern in which more than one suicidal method is applied in the purpose of inducing death. The present paper aims to review complex suicide literature shortly and investigate an unusual planned complex suicide incident, the rarity of which is attributable to the combination of suicide methods as well as the type and quantity of substances applied to induce poisoning. A 33-year-old man with a history of psychotic depression was found dead in his bedroom lying within a large quantity of blood...

Isolated scaphoid dislocations are extremely rare injuries and are commonly associated with significant ligamentous disruptions. A dorsiflexion-supination force upon the hand is considered as the most common mechanism of injury. Different treatment options have been proposed for the management of this uncommon entity, ranging from conservative treatment with closed reduction and casting to a wide range of open or percutaneous surgical techniques. In this article, we reported ona case of this rare injury managed with open reduction and pinning along with ligamentous reconstruction...

Background: Mismanagement of asymptomatic patients with positive urine cultures (referred to as asymptomatic bacteriuria [ASB] in the literature) promotes antimicrobial resistance and results in unnecessary antimicrobial-related adverse events and increased health care costs. Methods: We conducted a systematic review and meta-analysis of studies that reported on the rate of inappropriate ASB treatment published from 2004 to August 2016. The appropriateness of antimicrobial administration was based on guidelines published by the Infectious Diseases Society of America...

Purpose: To present a rare case of a patient with a 12-cm posttraumatic right subclavian artery aneurysm successfully treated with aneurysmectomy and innominate-axillary bypass. Case report: A 54-year-old man presented to the emergency department due to progressive dyspnea and hoarseness of voice. His medical record was unremarkable except that he had right-sided pneumothorax and multiple rib fractures from a car accident 16 years ago. A chest X-ray showed a mass in the upper lobe of the right lung, and the patient was hospitalized for further investigation...

Introduction: Malignant pleural effusion (MPE) is common and currently in UK there are an estimated 50 000 new cases of MPE per year. Talc pleurodesis remains one of the most popular methods for fluid control. The value of thoracic ultrasound (TUS) imaging, before and after pleurodesis, in improving the quality and efficacy of care for patients with MPE remains unknown. Additionally, biomarkers of successful pleurodesis including measurement of pleural fluid proteins have not been validated in prospective studies...
