Dual‐Graded Microstructure Engineering for Flexible Piezoresistive Sensors with High Sensitivity and Broad Linear Range in Physiological Monitoring

Advanced Science, EarlyView.
A flexible piezoresistive pressure sensor with dual‐graded microstructures achieves both high sensitivity (69.8 kPa⁻¹) and a broad linear range up to 300 kPa (R2 = 0.997). Synergizing structural deformation and tunneling conduction, it enables rapid, stable, and accurate detection of subtle physiological signals, offering a scalable and cost‐effective ...

Quadricuspid aortic valve [PDF]

European Journal of Echocardiography, 2007
A 57-year-old woman presented with a history of dyspnea on exertion since 4 months prior to admission. She denied chest pain. Her medical history was not significant. Physical examination revealed wide pulse pressure and arterial hypertension (170/65 mmHg). A diastolic murmur of grade 4/6 was heard at the …

BACE2‐Induced Aberrant Lymphatic Network Aggravates the Local Inflammation in Arteriovenous Fistulas With Hyperphosphatemia

Advanced Science, EarlyView.
Vascular endothelial growth factor (VEGF)‐C secreted by Pi16+ fibro‐progenitors lays the foundation of lymphatic network in mouse arteriovenous fistulas (AVFs), whereas the elevated phosphate (Pi) in 5/6‐nephrectomy (Nx) mouse activates p‐ERK/p‐SP1/BACE2 pathway to generate additional soluble VEGFR‐3, which causes VEGF‐C unresponsiveness and defective ...

Ascending aortic aneurysm and aortic valve dysfunction in bicuspid aortic valve disease

, 2013
BACKGROUND: The relationship of aortic valve dysfunction and ascending aortic aneurysm is unclear in adults with bicuspid aortic valve disease. METHODS: We retrospectively studied 134 consecutive out-patients (98 men, 36 women aged 43+/-18years) with ...

Clonal haematopoiesis in patients with degenerative aortic valve stenosis undergoing transcatheter aortic valve implantation

European Heart Journal, 2019
Aims Clonal haematopoiesis of indeterminate potential (CHIP), defined as the presence of an expanded somatic blood cell clone without other haematological abnormalities, was recently shown to increase with age and is associated with coronary artery ...

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

Advanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.
