One‐Step Covalent Biofunctionalization of Tubular Constructs Enabled by Surface‐Embedded Radicals

open access: yesAdvanced Materials Technologies, EarlyView.
Uniform covalent biofunctionalization of tubular constructs is achieved in one step using surface‐embedded radicals generated by a novel plasma immersion ion implantation (PIII) technology. This scalable, solvent‐free technology advances bioengineered tubes for tissue engineering and implant applications.

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

open access: yesAdvanced 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 ...

Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

open access: yes, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

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

open access: yesAdvanced 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.
