Characterization and influence of cardiac background sodium current in the atrioventricular node
Abstract Background inward sodium current (IB,Na) that influences cardiac pacemaking has been comparatively under-investigated. The aim of this study was to determine for the first time the properties and role of IB,Na in cells from the heart's...

The effectiveness of small changes for pressure redistribution; using the air mattress for small changes
Abstract Observing small changes (SCs) at specific sites is a new form of managing changes in position. We investigated SCs at specific sites considering interface pressure, contact area, body alignment and physical sensation in nine healthy female...

In vivo performance of novel soybean/gelatin-based bioactive and injectable hydroxyapatite foams
Abstract Major limitations of calcium phosphate cements (CPCs) are their relatively slow degradation rate and the lack of macropores allowing the ingrowth of bone tissue. The development of self-setting cement foams has been proposed as a suitable...

Early phase glucagon and insulin secretory abnormalities, but not incretin secretion, are similarly responsible for hyperglycemia after ingestion of nutrients
Abstract Aims Hypersecretion of glucagon and reduced insulin secretion both contribute to hyperglycemia in type 2 diabetes (T2DM). However, the relative contributions of impaired glucagon and insulin secretions in glucose...

Ginsenoside-Rb2 displays anti-osteoporosis effects through reducing oxidative damage and bone-resorbing cytokines during osteogenesis
Abstract Reactive oxygen species (ROS) are a significant pathogenic factor of osteoporosis. Ginsenoside-Rb2 (Rb2), a 20(S)-protopanaxadiol glycoside extracted from ginseng, is a potent antioxidant that generates interest regarding the bone...

Automatic optimal filament segmentation with sub-pixel accuracy using generalized linear models and B-spline level-sets
Abstract Biological filaments, such as actin filaments, microtubules, and cilia, are often imaged using different light-microscopy techniques. Reconstructing the filament curve from the acquired images constitutes the filament segmentation problem....

Diastolic function alteration mechanisms in physiologic hypertrophy versus pathologic hypertrophy are elucidated by model-based Doppler E-wave analysis
Abstract Athletic training can result in increased left ventricular (LV) wall thickness, termed physiologic hypertrophy (PhH). By contrast, pathologic hypertrophy (PaH) can be due to hypertension, aortic stenosis, or genetic mutation causing...

Continuous positive airway pressure therapy converted atrial fibrillation in a patient with obstructive sleep apnea
Abstract Background Obstructive sleep apnea (OSA) is one of the possible causes of atrial fibrillation (AF). Continuous positive airway pressure (CPAP) therapy may lower the recurrence rate of AF after cardioversion to normal sinus ...

Usage of Wireless Myon 320 Surface Electromyography (sEMG) System in Recording Motorcyclist Muscle Activities on Real Roads: A Case Study
Abstract This case study was conducted to determine signal transfer challenges and limitations that researchers tend to experience while using a wireless Myon 320 sEMG system during a real on-road motorcycle riding experiment. Eight muscle groups...

Decoding visual object categories from temporal correlations of ECoG signals
Abstract How visual object categories are represented in the brain is one of the key questions in neuroscience. Studies on low-level visual features have shown that relative timings or phases of neural activity between multiple brain locations...

A portable low-cost long-term live-cell imaging platform for biomedical research and education
Abstract Time-resolved visualization and analysis of slow dynamic processes in living cells has revolutionized many aspects of in vitro cellular studies. However, existing technology applied to time-resolved live-cell microscopy is often immobile,...

Application of stochastic phenomenological modelling to cell-to-cell and beat-to-beat electrophysiological variability in cardiac tissue
Abstract Variability in the action potential of isolated myocytes and tissue samples is observed in experimental studies. Variability is manifested as both differences in the action potential (AP) morphology between cells (extrinsic variability),...

Material properties of components in human carotid atherosclerotic plaques: A uniaxial extension study
Abstract Computational modelling to calculate the mechanical loading within atherosclerotic plaques has been shown to be complementary to defining anatomical plaque features in determining plaque vulnerability. However, its application has been...
