The potential sources of 16 PAHs in surface sediments from highly tourism activities of Chalong bay, Phuket province, Thailand were apportioned. Twenty-eight of sediment samples were collected by using van Veen grab Sampler from Chalong bay, Phuket. Quantitative analysis of the 16 PAHs which categorized according to the USEPA was analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). Moreove...
When asked to combine two pieces of evidence, one diagnostic and one non-diagnostic, people show a dilution effect: the addition of non-diagnostic evidence dilutes the overall strength of the evidence. This non-normative effect has been found in a variety of tasks and has been taken as evidence that people inappropriately combine information. We investigated the dilution effect using simple per...
Recent cross-sectional and longitudinal studies indicate that measurements of peripheral blood carbonyl stress markers such as the advanced glycation end product (AGE) pentosidine and the reactive carbonyl-detoxifying B6 vitamin pyridoxal could be used as therapeutic biological markers in subpopulations of schizophrenia patients. Glyceraldehyde-derived AGEs (Glycer-AGE) have strong neurotoxicit...
interest the article by Chew and colleagues [1], who studied the role of extravascular lung water (EVLW) indices in improving the diagnostic accuracy of lung injury (LI) in patients with shock. It is not clear how the patients included in this study are diff erent from those included in previous ones [2,3]. Indeed, in this work, 34 (67%) of patients had septic shock and up to 33 (65%) of patien...
BACKGROUND Differential diagnosis of ovarian masses can influence both treatment selection and prognosis of ovarian tumor patients. A comprehensive review was performed with respect to the diagnostic value of conventional ultrasonography, Doppler ultrasonography and contrast-enhanced ultrasonography (CEUS) in differentiating benign from malignant ovarian masses. METHODS Databases were searche...
AIM This paper reports an investigation of the diagnostic accuracy of the Care Dependency Scale (CDS). BACKGROUND Assessment tools can be described in terms of diagnostic accuracy, or the ability to correctly classify subjects into clinically relevant subgroups. Diagnostic accuracy can be determined by several techniques as sensitivity, specificity, receiver operating curve analysis and likel...
BACKGROUND The configuration of the anterior communicating artery (AcomA) complex is important in the endovascular treatment of AcomA complex aneurysms. In cases of codominant anterior cerebral arteries (ACA), coil embolization may result in inadvertent occlusion of the contralateral ACA due to poor visualization. A second diagnostic catheter in the contralateral carotid artery may help with vi...
STUDY OBJECTIVE Multiple studies have evaluated capnography for the diagnosis of pulmonary embolism; accordingly, we conduct a meta-analysis of these trials. METHODS We performed a systematic search from 1990 to 2011, using MEDLINE, EMBASE, and the Cochrane Library, including studies evaluating capnography as a diagnostic tool alone or in conjunction with other tests. After study quality eval...
BACKGROUND To assess the accuracy of findings from the clinical history, symptoms, signs and diagnostic tests (ECG, CXR and natriuretic peptides) in relation to the diagnosis of left ventricular systolic dysfunction (LVSD) in a primary care setting. METHODS Diagnostic accuracy systematic review, we searched Medline (1966 to March 2008), EMBASE (1988 to March 2008), Central, Cochrane and ZETOC...
