A study on stability analysis of atrial repolarization variability using ARX model in sinus rhythm and atrial tachycardia ECGs [PDF]

open access: yes, 2016
© 2016 Elsevier Ireland Ltd Background The interaction between the PTa and PP interval dynamics from the surface ECG is seldom explained. Mathematical modeling of these intervals is of interest in finding the relationship between the heart rate and ...

Influence of Layering and Curie Temperature Uncertainty on the Performance of Multilayer Active Magnetic Regenerators

open access: yesAdvanced Functional Materials, EarlyView.
This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.

Prolonged PR interval, first-degree heart block and adverse cardiovascular outcomes: a systematic review and meta-analysis [PDF]

open access: yes, 2016
Objective: First-degree atrioventricular block is frequently encountered in clinical practice and is generally considered a benign process. However, there is emerging evidence that prolonged PR interval may be associated with adverse outcomes. This study

Imaging of Lipid Droplets in Living Cells and Mice with Metabolic Dysfunction‐Associated Steatotic Liver Disease via a Galactose‐Modified Supramolecular Near‐Infrared Fluorescent Glycoprobe

open access: yesAdvanced Functional Materials, EarlyView.
A galactose‐modified supramolecular near‐infrared (NIR) glycoprobe, TCF‐FBN@Gal‐BSA, enables targeted delivery to the liver through the asialoglycoprotein receptor (ASGPR) and facilitates liver‐targeting fluorescence visualization of lipid droplets (LDs) in metabolic dysfunction‐associated steatotic liver disease (MASLD) mice.

3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...
