Assessment of left ventricular diastolic function with cardiovascular MRI: what radiologists should know [PDF]

, 2012
Diastolic dysfunction is a common entity and the predominant cause of heart failure in 40%-50% of patients. Diagnosis of diastolic dysfunction is clinically relevant and is associated with a poor prognosis.

Ultra‐Sensitive and Linear Flexible Pressure Sensors with Tri‐Scale Graded Microstructures for Advanced Health Monitoring and Robotic Perception

Advanced Science, EarlyView.
A flexible piezoresistive sensor with a 3D tri‐scale graded microstructure is proposed, overcoming the trade‐off between sensitivity and linearity. The device achieves ultra‐high sensitivity (138.6 kPa−1), a broad linear range (400 kPa, R2 = 0.99), and exceptional stability (24 000 repeated loading cycles), enabling precise detection of physiological ...

Biomimetic Multiscale‐Structured Biomass Graphene/Polyurethane Sponge Composite for Flexible Pressure Sensors and Intelligent Cushioning Materials

Advanced Science, EarlyView.
In this study, a multifunctional conductive sponge composite (MAPU) is developed using a biomimetic, hierarchical construction strategy emulating the growth process of natural wood. This approach involved integrating biomass‐derived graphitic nanoflakes, synthesized from luffa vine (LVGN), into a polyurethane (PU) sponge matrix.

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

Advanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.

Development of an efficient mice model of cancer‐associated cardiac cachexia

Animal Models and Experimental Medicine, EarlyView.
This work establishes a preclinical framework for targeting ubiquitin pathways to mitigate the morbidity of cancer‐related cardiopathy. Our integrated approach delineates a hierarchical progression from subcellular dysfunction to macroscopic cardiac deterioration. These findings mechanistically link tumor‐induced cachexia to cardiac dysfunction through
