in this work, a novel method is described for the preconcentration of pb2+, cd2+ and zn2+ ions in environmental samples using uniform silanized mesopor (lus-1) functionalized by ethylenediamine groups as a new extractant. the determination of ions is done by inductively coupled plasma optical emission spectrometry (icp-oes). the extraction time and efficiency, ph and amount of adsorbent, minimu...

Objective: The purpose of the study was to establish validity abdominal evaluation lower uterine segment (LUS) thickness in patients having a previous cesarean section (CS) predicting rupture, and evaluate if there is any effect number surgeries on adverse maternal perinatal outcomes.
 Materials methods: A prospective case-control carried out between December 2017 June 2018 Dr. Zekai Tahir...

OBJECTIVES Interstitial lung disease (ILD) is a frequent extra-articular manifestation of RA associated with increased mortality. High-resolution CT (HRCT) is used for diagnosis and follow-up, but its accuracy is counterbalanced by high costs and radiological risk. In the presence of ILD, lung US (LUS) detects vertical artefacts called B-lines. The aims of the present study were to evaluate the...

BACKGROUND The role of staging laparoscopy (SL) with laparoscopic ultrasound (LUS) in patients with resectable colorectal liver metastases (CRLM) remains controversial. METHODS A meta-analysis of all studies (from 1998 to the present) on the effect of SL/LUS in patients with potentially resectable CRLM with respect to alteration in surgical management was performed. RESULTS Twelve studies s...

Objective: to investigate the accuracy of 2D and 3D ultrasound in measurement of Cesarean section (CS) scar thickness. Study design: A prospective observational study conducted on 75 pregnant women with previous 1 or 2 CS candidates for elective CS. Evaluation of LUS using 2D and 3D transabdominal and transvaginal ultrasound is then correlated to scar integrity assessed intraoperatively. Result...

Intra-operative contact ultrasound is a sensitive method of detecting liver tumours. The aim of this study was to compare the sensitivity of open contact ultrasound (OUS) of the liver with laparoscopic contact ultrasound (LUS). Hypoechoic "lesions" were created in 5 fresh pig livers by inserting 28 grapes via small incisions in the inferior surface. The size (range 8-25 mm) and location of each...

Background: Guidelines do not currently recommend the use of lung ultrasound (LUS) as an alternative to chest X-ray (CXR) or chest computerized tomography (CT) scan for the diagnosis of pneumonia. We conducted a meta-analysis to summarize existing evidence of the diagnostic accuracy of LUS for pneumonia in adults. Methods: We conducted a systematic search of published studies comparing the diag...

OBJECTIVE To evaluate the accuracy of antenatal sonographic measurement of lower uterine segment (LUS) thickness in the prediction of risk of uterine rupture during a trial of labor (TOL) in women with a previous Cesarean section (CS). METHODS PubMed and EMBASE were searched to identify articles published on the subject of sonographic LUS measurement and occurrence of a uterine defect after d...

Laser ultrasonic (LUS) receivers based on photorefractive (PR) materials are contactless and adaptive interferometers, which are used widely for materials characterization. Here, we present a simple LUS interferometer at 532 nm operating wavelength based on organic PR polymer composites (PVK/ECZ/C60) doped with the nonlinear chromophore 4-[4-(diethylamino)-2-hydroxybenzylideneamino] benzonitril...

A potentiometric sensor is reported for the mercury(II) detection, which uses substituted thiourea-functionalized nanoporous silica (FTU-LUS-1) as the sensitive material. Substituted thiourea (FTU) and FTU-LUS-1 were first prepared and then characterized by 1H NMR, 19F NMR, 13C NMR, FTIR, XRD, TG and CNS elemental analysis. The electrodes with FTU-LUS-1 proportion of 10.0 wt% demonstrated very ...
