Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

The role of large arteries in controlling blood flow to the hand during severe local cooling. [PDF]

, 1995
PhDCold vasodilatation describes the increase in blood flow that follows initial vaso constriction when an extremity is exposed to an environment colder than 12'C. It appears to be due mainly to cold paralysis of local resistance vessels.

Increased pain sensitivity in low blood pressure. [PDF]

, 2008
. There is broad evidence for a functional interaction between the cardiovascular and pain regulatory systems. One result of this interaction is the reduced sensitivity to acute pain in individuals with elevated blood pressure, which has been established

Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

Advanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

Advanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Topically Delivered Treg‐Attracting Microparticle‐Hydrogel Composites Recruit Regulatory T Cells and Limit Cardiac Injury After Severe Ischemia

Advanced Healthcare Materials, EarlyView.
CCL22‐releasing PLGA microparticles (MP) suspended in topically applied hydrogels (HEART) establish a sustained chemokine gradient at the injured myocardium. HEART recruits CCR4+ regulatory T cells, reduces infarct size and graft fibrosis, and improves cardiac function.

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

Advanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

The BOLD MRI response of the brain to alterations in arterial blood pressure

The impact of blood pressure changes on cerebral blood flow is an important area of investigation. The cerebral autoregulation mechanism acts to maintain blood supply to the brain, despite changes in blood pressure.
