Intradialytic aerobic exercise training ameliorates symptoms of restless legs syndrome and improves functional capacity in patients on hemodialysis
(2008)We present the first study on the influence of exercise training on restless legs syndrome (RILS) in patients on hemodialysis (HD). Restless legs syndrome has been treated pharmacologically with satisfactory results; ... -
METRADISC-XL: A program for meta-analysis of multidimensional ranked discovery oriented datasets including microarrays
(2012)A comprehensive software for performing meta-analysis of ranked discovery oriented datasets, such as those derived from microarrays or other high throughput technologies, and for testing between-study heterogeneity for ... -
A multipurpose quality assurance phantom for the small animal radiation research platform (SARRP)
(2012)In this work, the suitability and performance of a mouse-size MOSFET (Mousefet) phantom is investigated for routine quality assurance (QA) of the small animal radiation research platform (SARRP). This Mousefet phantom is ... -
Non-invasive measurement of tibialis anterior muscle temperature during rest, cycling exercise and post-exercise recovery
(2015)We introduce a non-invasive and accurate method to assess tibialis anterior muscle temperature (Tm) during rest, cycling exercise, and post-exercise recovery using the insulation disk (INDISK) technique. Twenty-six healthy ... -
Non-Pharmacological Management of Periodic Limb Movements During Hemodialysis Session in Patients With Uremic Restless Legs Syndrome
(2010)Restless legs syndrome (RLS) is very common in hemodialysis patients. RLS induces motor excitability and discomfort during rest periods, and those symptoms have also been observed during hemodialysis sessions. The aim of ... -
A novel tool for segmenting 3D medical images based on generalized cylinders and active surfaces
(2013)Three-dimensional (3D) medical imaging has been incorporated in routine clinical practice, since the required infrastructure has become increasingly affordable. New algorithms and applications are needed to serve the ... -
NTCP modelling and pulmonary function tests evaluation for the prediction of radiation induced pneumonitis in non-small-cell lung cancer radiotherapy
(2007)This work aims to evaluate the predictive strength of the relative seriality, parallel and Lyman-Kutcher-Burman (LKB) normal tissue complication probability (NTCP) models regarding the incidence of radiation pneumonitis ... -
Numerical modeling of simulated blood flow in idealized composite arterial coronary grafts: Steady state simulations
(2007)This paper presents a comparative study of simulated blood flow in different configurations of simplified composite arterial coronary grafts (CACGs). Even though the composite arterial grafting is increasingly used in ... -
Numerical modelling of simulated blood flow in idealized composite arterial coronary grafts: Transient flow
(2008)In composite arterial coronary grafts (CACGs), transport phenomena and geometry may considerably alter blood flow dynamics. CACGs aim at revascularizing pathological arteries according to the human anatomy. However, the ... -
Osseointegration of Osseotite (R) and machined-surfaced titanium implants in membrane-covered critical-sized defects: a histologic and histometric study in dogs
(2007)The texture of an implant's surface can influence the rate and extent of bone fixation as expressed by the amount of linear bone-to-implant contact (BIC). The purpose of this study was to compare the bone density and linear ... -
P wave analysis indices in young healthy men: Data from the Digital Electrocardiographic Study in Hellenic Air Force Servicemen (DEHAS)
(2003)P wave analysis from the 12-lead ECG is a recent contribution of noninvasive electrocardiology. P wave analysis indices (maximum and minimum P wave duration, P wave dispersion [P-dis = P-max - P-min], adjusted P wave ... -
Postmortem Image Analysis of Sheep Cortical Leptomeningeal Space and Vasculature: Theoretical Implications on Brain Surface Dialysis
(2011)The vascular surface distribution of the subarachnoid space has not been studied extensively. The aim of our study was to develop a method of computer-assisted estimation of the distribution of the vascular network in the ... -
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. ... -
The relationship between jumping performance and isokinetic strength of hip and knee extensors and ankle plantar flexors
(2002)The purpose of this study was to examine the relationship between vertical jumping performance and isokinetic moment of force of knee extensors, hip extensors and ankle plantar flexors in adult males. Twenty-nine males ... -
Short vs. long length of rectus femoris during eccentric exercise in relation to muscle damage in healthy males
(2005)Background. We investigated the effects of short vs. long length of rectus femoris during eccentric exercise of similar range of motion on selected muscle damage indicators. Methods. Using all isokinetic dynamometer at ... -
Sodium and body fluid homeostasis in profiling hemodialysis treatment
(2002)Acute adverse side-effects of hemodialysis such as hypotension, muscle cramps, osmotic imbalance and thirst are induced by the interference with fluid and electrolyte balance occurring during treatment. Changes in osmolarity ... -
Support Vectors Machine-based identification of heart valve diseases using heart sounds
(2009)Taking into account that heart auscultation remains the dominant method for heart examination in the small health centers of the rural areas and generally in primary healthcare set-ups, the enhancement of this technique ... -
Telomere Length in Peripheral Blood Mononuclear Cells of Patients on Chronic Hemodialysis Is Related With Telomerase Activity and Treatment Duration
(2015)Telomere shortening to a critical limit is associated with replicative senescence. This process is prevented by the enzyme telomerase. Oxidative stress and chronic inflammation are factors accelerating telomere loss. Chronic ... -
