DEVELOPMENTS IN ROC SURFACE ANALYSIS AND ASSESSMENT OF DIAGNOSTIC MARKERS IN THREE-CLASS CLASSIFICATION PROBLEMS
(2014)This article reviews current state of the art of ROC surface analysis and illustrates its use through an application on a pancreatic cancer diagnostic marker. Receiver Operating Characteristic (ROC) surfaces have been ... -
Effect of anticoagulant and storage conditions on platelet size and clumping in healthy dogs
(2008)The potential impact of preanalytical factors, such as type of anticoagulant, storage temperature, and time, on the formation of macroplatelets and platelet aggregates (platelet clumping) in dogs is largely elusive. The ... -
The effect of lung expansion and positive end-expiratory pressure on anesthetized children
(2008)BACKGROUND: Imaging studies have shown that general anesthesia in children results in atelectasis. Lung recruitment total lung capacity (TLC) maneuvers plus positive end-expiratory pressure (PEEP) are effective in preventing ... -
Efficiency of a pneumatic device in controlling cuff pressure of polyurethane-cuffed tracheal tubes: a randomized controlled study
(2013)Background: The primary objective of this study was to determine the efficiency of a pneumatic device in controlling cuff pressure (Pcuff) in patients intubated with polyurethane-cuffed tracheal tubes. Secondary objectives ... -
Evaluation of dose-response models and parameters predicting radiation induced pneumonitis using clinical data from breast cancer radiotherapy
(2005)The purpose of this work is to evaluate the predictive strength of the relative seriality, parallel and LKB normal tissue complication probability (NTCP) models regarding the incidence of radiation pneumonitis, in a large ... -
Impact of fine or large needle aspiration on the dog's testis in vitro ultrasonographic, bacteriological, gross anatomy and histological assessment
(2010)Despite its extensive use for evaluation of spermatogenesis and assisted reproduction the safety and consequences of fine (FNA) and large needle aspiration (LNA) to the testicular parenchyma and its normal function have ... -
Lack of association between the UDP-glucuronosyltransferase 1A1 (UGT1A1) gene polymorphism and the risk of benign prostatic hyperplasia in Caucasian men
(2013)Glucuronidation, mediated by the UDP-glucuronosyltransferase 1A1 (UGT1A1) enzyme, is an important metabolic process during which steroids are converted to more easily excreted compounds in steroid target tissues, such as ... -
A method for limiting pitfalls in the production of enhancement kinetic curves in 3T dynamic magnetic resonance mammography
(2012)Purpose: The aim of the present study is to investigate means for the reduction or even elimination of enhancement kinetic curve errors due to breast motion in order to avoid pitfalls and to increase the sensitivity and ... -
Prediction of AVM obliteration after stereotactic radiotherapy using radiobiological modelling
(2002)This study was carried out in order to derive the radiobiological parameters of the dose-response relation for the obliteration of arteriovenous malformation (AVM) following single fraction stereotactic radiotherapy. ... -
Repeatability of Retinal Macular Thickness Measurements in Healthy Subjects and Diabetic Patients with Clinically Significant Macular Edema: Evaluation of the Follow-Up System of Spectralis Optical Coherence Tomography
(2015)Background: It was the aim of this study to compare the repeatability of Spectralis optical coherence tomography (OCT) retinal thickness measurements in healthy subjects and diabetic patients with clinically significant ... -
Urine Levels of Catecholamines in Greek Children With Obstructive Sleep-Disordered Breathing
(2009)Introduction: Adults with obstructive sleep apnea have increased sympathetic activity It was hypothesized that in children with symptoms of obstructive sleep-disordered breathing (SDB), morning urine levels of catecholamines ...
