Vascular segmentation in hepatic CT images using adaptive threshold fuzzy connectedness method
Source, July 01, 2015
Background: Fuzzy connectedness method has shown its effectiveness for fuzzy object extraction in recent years. However, two problems may occur when applying it to hepatic vessel segmentation task. One is the excessive computational cost, and the other is the difficulty of choosing a proper threshol...
The effect of simvastatin treatment on endothelial cell response to shear stress and tumor necrosis factor alpha stimulation
Source, July 01, 2015
Background: Statin drugs are one of the most commonly prescribed pharmaceuticals by physicians. By blocking the rate-limiting step in the cholesterol biosynthesis pathway, statins inhibit cholesterol synthesis, which benefits patient health. However, since many other important cellular processes are...
Quality estimation of the electrocardiogram using cross-correlation among leads
Source, July 01, 2015
Background: Fast and accurate quality estimation of the electrocardiogram (ECG) signal is a relevant research topic that has attracted considerable interest in the scientific community, particularly due to its impact on tele-medicine monitoring systems, where the ECG is collected by untrained techni...
The extraction of the new components from electrogastrogram (EGG), using both adaptive filtering and electrocardiographic (ECG) derived respiration signal
Source, July 01, 2015
Electrogastrographic examination (EGG) is a noninvasive method for an investigation of a stomach slow wave propagation. The typical range of frequency for EGG signal is from 0.015 to 0.15?Hz or (0.015-0.3?Hz) and the signal usually is captured with sampling frequency not exceeding 4?Hz. In this pape...

Contributing reviewersThe Editors of BioMedical Engineering OnLine would like to thank all the Reviewers who have contributed to the journal in Volume 13 (2014).
Optimizing parameters of an open-source airway segmentation algorithm using different CT images
Source, July 01, 2015
Background: Computed tomography (CT) helps physicians locate and diagnose pathological conditions. In some conditions, having an airway segmentation method which facilitates reconstruction of the airway from chest CT images can help hugely in the assessment of lung diseases. Many efforts have been m...
Segmentation of white blood cells and comparison of cell morphology by linear and naïve Bayes classifiers
Source, July 01, 2015
Background: Blood smear microscopic images are routinely investigated by haematologists to diagnose most blood diseases. However, the task is quite tedious and time consuming. An automatic detection and classification of white blood cells within such images can accelerate the process tremendously. I...
Analysis of short-term heart rate and diastolic period variability using a refined fuzzy entropy method
Source, July 01, 2015
Background: Heart rate variability (HRV) has been widely used in the non-invasive evaluation of cardiovascular function. Recent studies have also attached great importance to the cardiac diastolic period variability (DPV) examination. Short-term variability measurement (e.g., 5?min) has drawn increa...
Recognition of activities of daily living in healthy subjects using two ad-hoc classifiers
Source, June 16, 2015
Background: Activities of daily living (ADL) are important for quality of life. They are indicators of cognitive health status and their assessment is a measure of independence in everyday living. ADL are difficult to reliably assess using questionnaires due to self-reporting biases. Various sensor-...
Computational modeling of peripheral pain: a commentary
Source, June 11, 2015
This commentary is intended to find possible explanations for the low impact of computational modeling on pain research. We discuss the main strategies that have been used in building computational models for the study of pain. The analysis suggests that traditional models lack biological plausibili...
