Descartes, corpuscles and reductionism : mechanism and systems in Descartes' physiology [PDF]

, 2015
I argue that Descartes explains physiology in terms of whole systems, and not in terms of the size, shape and motion of tiny corpuscles (corpuscular mechanics). It is a standard, entrenched view that Descartes’s proper means of explanation in the natural

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...

Formation of the Ventricles

The Scientific World Journal, 2006
The formation of the ventricles of the heart involves numerous carefully regulated temporal events, including the initial specification and deployment of ventricular progenitors, subsequent growth and maturation of the ventricles through “ballooning” of ...

PRMT1 Ablation in Endothelial Cells Causes Endothelial Dysfunction and Aggravates COPD Attributable to Dysregulated NF‐κB Signaling

Advanced Science, EarlyView.
This study investigates the role of protein arginine methyltransferase 1 (PRMT1) in endothelial cells (ECs) in chronic obstructive pulmonary disease (COPD). Mice with endothelial‐specific PRMT1 deletion develop pulmonary hemorrhage, inflammation, and apoptosis, driven by excessive nuclear factor kappa B activation.

Pixel-wise Segmentation of Right Ventricle of Heart [PDF]

arXiv, 2019
One of the first steps in the diagnosis of most cardiac diseases, such as pulmonary hypertension, coronary heart disease is the segmentation of ventricles from cardiac magnetic resonance (MRI) images. Manual segmentation of the right ventricle requires diligence and time, while its automated segmentation is challenging due to shape variations and ...
