Undoped and Au-doped ZnO-nanorods were synthesized in the presence of ultrasound and loaded on activated carbon following characterization by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmittance electron microscopy (TEM), UV-vis spectrophotometry and Fourier transform infrared spectroscopy (FTIR). The Au-doped ZnO-nanorod-loaded activated carbon (Au-ZnO-NRs-AC) was used for the simultaneous removal of methylene blue (MB) and auramine O (AO) from aqueous solutions. Central composite design (CCD) under response surface methodology (RSM) was applied to model and optimize the dyes removal versus adsorbent mass, pH, and initial dyes concentration and sonication time as well as to investigate the possible interaction between these variables...

Cardiac tumours are a rare, but often devastating, clinical diagnosis. They encompass a broad set of lesions that include both neoplastic and non-neoplastic conditions. Cardiac tumours are often diagnosed incidentally during work-up for other conditions, or during ultrasound, CT, or MRI scans for unusual or nonspecific symptoms. In the past decade, important changes have been made in the nomenclature and the recommendations for diagnosis of cardiac tumours, as highlighted by the WHO's 2015 revision of the classification of cardiac tumours...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) diagnoses and stages mediastinal lymph node pathology. This retrospective study determined the relationship between EBUS-TBNA utility and non-small cell lung cancer (NSCLC) stage, lymph node size, and positron emission tomography (PET) standard uptake values (SUV), and the utility of neck ultrasound in bulky mediastinal disease. METHODS: Data of 284 consecutive patients who had undergone EBUS-TBNA was collected...

BACKGROUND: Oesophageal GIST (ESOGIST) are very rare tumours requiring special consideration regarding diagnosis, surgical management, and perioperative treatment. METHODS: A retrospective study was conducted across 9 centres in the French Sarcoma Group (FSG) to characterize all patients in the years 2000-2014. RESULTS: Seventeen patients (pts) with primary localized ESOGIST were identified, with median age 69 years (36-81) and 11 females...

INTRODUCTION: Minimally invasive adrenalectomy has become the gold standard for surgery of the suprarenal gland. Retroperitoneoscopic adrenalectomy with dorsal approach is preferred. The aim of our case report is to discuss potential complications that may arise from retroperitoneoscopic adrenalectomy, specifically an intra-operative injury of the inferior vena cava. CASE REPORT: A 47-year-old male patient was admitted to undergo elective adrenalectomy on the right side...

As ultrasonography continues to become integrated into undergraduate medical education, there have been concerns raised about the use of volunteer models and the ability to maintain patient privacy during scanning sessions. To date, there have been no reports on how instructors should manage situations in which incidental findings are made during educational ultrasonography sessions. We present three different examples of incidental findings that occurred at our institution and the various approaches taken by the instructors...

PURPOSE: To evaluate the relationship between anterior cerebral artery (ACA) velocities (and ancillary parameters) and ACA infarction following aneurysmal subarachnoid hemorrhage (aSAH), and to examine the factors that influence velocities. METHODS: Retrospective investigation of 500 consecutive aSAH patients. ACA mean velocities (Vm) were evaluated by daily transcranial ultrasound during the early (days 1-4) and late (days 5-20) periods posthemorrhage. Presence and timing of acute ACA infarctions were identified by serial retrospective review of cerebral computerized tomography (CT) scans...

Objective.: Position of joints might influence the result of US examination in patients with RA. The purpose of this work was to compare grey-scale (GS) and power Doppler (PWD) findings obtained in neutral vs flat position of hands. Methods.: A cross-sectional study of 42 RA patients with active disease. Two dimensional and 3D sonography of wrists and MCP joints were conducted in two different joint positions: neutral position, which is a slight flexion of the fingers with relaxed extensor muscles; and flat position, where all palm and volar sides of fingers touch the Table...

The purpose of this study was to semi-quantitatively assess the evidence on the value of ultrasound (US) for assessment of haemophilic arthropathy (HA) in children and adults based on the following questions: (1) Does early diagnosis of pathological findings, using available US techniques, impact the functional status of the joint? (2) Do current available US techniques have the ability to accurately detect pathological changes in target joints in haemophilic patients? (3) Does treatment (prophylaxis) improve US evidence of haemophilic arthropathy in children and adults? (4) Is there any association between various US scoring systems and other clinical/radiological constructs? Of the 6880 citations identified searching databases such as MEDLINE, Embase, CENTRAL and Web of Science, 20 articles investigating either the diagnostic accuracy of US and/or US scanning protocols and scoring systems for assessment of HA met the inclusion criteria for the study...

In this work, ultrasound-assisted adsorption of an anionic dye, sunset yellow (SY) and cationic dyes, malachite green (MG), methylene blue (MB) and their ternary dye solutions onto Cu@ Mn-ZnS-NPs-AC from water aqueous was optimized by response surface methodology (RSM) using the central composite design (CCD). The adsorbent was characterized using Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX) and EDX mapping images. The effects of various parameters such as pH, sonication time, adsorbent mass and initial concentrations of SY, MG and MB were examined...

Alpha manganese dioxide (α-MnO2) nanorods have been covalently functionalized with stearic acid by solvothermal method. The α-MnO2-stearic acid nanorods were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The amount of stearic acid grafted onto α-MnO2 surface was determined about 41wt% by thermogravimetric analysis. The α-MnO2-stearic acid nanorods was used as nanofiller for the preparation of poly(vinyl alcohol) (PVA) nanocomposites (NCs)...

The influence of high-intensity ultrasound (HIU) on the technofunctional properties and structure of jackfruit seed protein isolate (JSPI) was investigated. Protein solutions (10%, w/v) were sonicated for 15min at 20kHz to the following levels of power output: 200, 400, and 600W (pulse duration: on-time, 5s; off-time 1s). Compared with untreated JSPI, HIU at 200W and 400W improved the oil holding capacity (OHC) and emulsifying capacity (EC), but the emulsifying activity (EA) and emulsion stability (ES) increased at 400W and 600W...
