Agonist and antagonist strength of ankle musculature in basketball players aged 12 to 17 years
(2006)Muscle strength and balance around the lower limb joints may play an important role for performance and injury prevention in basketball. The purpose of this study was to examine isokinetic "functional" and "conventional" ... -
Automated differentiation of glioblastomas from intracranial metastases using 3T MR spectroscopic and perfusion data
(2013)Purpose Differentiation of glioblastomas from metastases is clinical important, but may be difficult even for expert observers. To investigate the contribution of machine learning algorithms in the differentiation of ... -
Automated sleep breath disorders detection utilizing patient sound analysis
(2012)Results of clinical studies suggest that there is a relationship between breathing-related sleep disorders and behavioral disorder and health effects. Apnea is considered one of the major sleep disorders with great accession ... -
Brain lesion classification using 3T MRS spectra and paired SVM kernels
(2011)The increased power and resolution capabilities of 3T Magnetic Resonance (MR) scanners have extended the reach of Magnetic Resonance Spectroscopy as a non-invasive diagnostic tool. Practical sensor calibration issues, ... -
Combined use of chondroitinase-ABC, TGF-beta 1, and collagen crosslinldng agent lysyl oxidase to engineer functional neotissues for fibiocartilage repair
(2014)Patients suffering from damaged or diseased fibrocartilages currently have no effective long-term treatment options. Despite their potential, engineered tissues suffer from inferior biomechanical integrity and an inability ... -
Dynamic behavior of suture-anastomosed arteries and implications to vascular surgery operations
(2015)Background: Routine vascular surgery operations involve stitching of disconnected human arteries with themselves or with artificial grafts (arterial anastomosis). This study aims to extend current knowledge and provide ... -
The Effect of Prolonged Intradialytic Exercise in Hemodialysis Efficiency Indices
(2011)Optimal hemodialysis (HD) dose is very important to patients' health and survival, and various indices of adequacy have been incorporated into the current clinical practice to monitor HD efficiency. Exercise during HD could ... -
Endothelin-1 Acutely Reduces the Permeability of Visceral Sheep Peritoneum In Vitro Through Both Endothelin-A and Endothelin-B Receptors
(2013)Mesothelium is an important part of the peritoneal barrier for water and ion transport, essential for effective peritoneal dialysis (PD). Peritoneal fibrosis has been associated with PD treatment failure. Endothelin-1 ... -
Enhancing classification accuracy utilizing globules and dots features in digital dermoscopy
(2015)The interest in image dermoscopy has been significantly increased recently and skin lesion images are nowadays routinely acquired for a number of skin disorders. An important finding in the assessment of a skin lesion ... -
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 ... -
Fast spectroscopic multiple analysis (FASMA) for brain tumor classification: a clinical decision support system utilizing multi-parametric 3T MR data
