Automatic feature extraction algorithms for the assessment of in-vitro electrical recordings of rat myocardium with ablation lesions

open access: yesCurrent Directions in Biomedical Engineering, 2017
Cardiac arrhythmias are a widely spread disease in industrialized countries. A common clinical treatment for this disease is radiofrequency ablation (RFA), in which high frequency alternating current creates a lesion on the myocardium.

The effect of L-arginine and L-NAME on myocardial capillary density in normal rats

open access: yesAdvanced Biomedical Research, 2013
Background: This study evaluated the effect of L-arginine (Nitric Oxide (NO) precursor) and L-NG-Nitroarginine Methyl Ester (L-NAME) (NO synthase inhibitor) on myocardial capillary density in normal rats.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

TUBERCULOSIS OF THE MYOCARDIUM. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1902
Previous to 1826 the existence of cardiac tuberculosis was denied. Tuberculosis of muscle was known to be rare and the heart, with its unceasing contractions, was considered immune. Again, the theory of the natural antagonism between cardiac disease and tuberculosis was almost universally accepted.

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Specific Inhibition of CYP4A Alleviates Myocardial Oxidative Stress and Apoptosis Induced by Advanced Glycation End-Products

open access: yesFrontiers in Pharmacology, 2019
High exposure to advanced glycation end-products (AGEs) may induce cardiotoxicity. However, the effects and mechanisms remain to be further clarified.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
