Relationship between Vascular Resistance and Sympathetic Nerve Fiber Density in Arterial Vessels in Children With Sleep Disordered Breathing

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundSleep disordered breathing in children is associated with increased blood flow velocity and sympathetic overactivity. Sympathetic overactivity results in peripheral vasoconstriction and reduced systemic vascular compliance, which increases ...

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...

Blood Flow Velocity in a Patient with Takayasu's Arteritis

Japanese Heart Journal, 1972
Blood flow velocity was recorded by using Doppler transcutaneous flowmeter and Doppler catheter flowmeter in an 18-year-old woman with Takayasu's arteritis. Although no right radial artery pulse was felt by palpation, significant decrease and slow rise of the peak blood flow velocity, and inconspicuous dicrotic notch was observed and recorded from the ...

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...
