Meniscus‐Guided Interfacial Ring‐by‐Ring Assembly for In Situ Fabrication of Tubular Hydrogels

Advanced Materials, EarlyView.
A tubular hydrogel fabrication method leveraging the meniscus effect at the oil‐water interface is presented. UV irradiation across the concave surface of the photocurable hydrogel precursor induces the formation of ring‐like hydrogel structures. Sequential ring‐by‐ring assembly within microchannels enables the construction of arteriole‐scale hydrogel ...

Considering Hematocrit is Essential When Using Arterial Spin Labeling MRI to Investigate Sex Differences in Cerebral Blood Flow

Clinical Neuroimaging
Background and Purpose Arterial spin labeling (ASL)‐MRI measures cerebral blood flow (CBF) by magnetically labeling red blood cells (RBC). ASL‐MRI shows reduced CBF in diseases including Alzheimer's Disease (AD).

Blood Electrical Impedance Closely Matches Whole Blood Viscosity as Parameter of Hemorheology and Inflammation

Applied Rheology, 2003
Red blood cell aggregation (RBCa) is a sensitive inflammation marker. RBCa determination from erythrocyte sedimentation rate, ESR, is used since long, but is unspecific unless corrected for hematocrit, Ht.

Multifunctional Wound Dressings: Melt Electrowritten Scaffolds Combined With Phytotherapeutic Composite Hydrogels

Advanced Materials Interfaces, EarlyView.
ABSTRACT The increasing prevalence of impaired wounds, caused mainly by diabetes or aging, alongside the growing number of bacterial infections, indicates the need for alternative tissue engineering solutions. In this study, we developed novel melt electrowritten (MEW) polycaprolactone (PCL) scaffolds incorporated with an alginate (Alg)–gelatin (Gel ...

A Quasi-Mechanistic Mathematical Representation for Blood Viscosity

Fluids, 2017
Blood viscosity is a crucial element for any computation of flow fields in the vasculature or blood-wetted devices. Although blood is comprised of multiple elements, and its viscosity can vary widely depending on several factors, in practical ...

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow

Advanced Materials Interfaces, EarlyView.
A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...

Shape Memory Polymer‐Based Flexible Pressure Sensor for Real‐Time Venous Thrombosis Monitoring

Advanced Materials Interfaces, EarlyView.
A shape‐memory tubular flexible pressure sensor with a 100‐mesh microstructured SMP‐PLA/MWCNTs sensing layer was developed for PICC‐mounted monitoring of thrombosis‐related pressure changes. The sensor combines high sensitivity (204 kPa−1), a fast response time (28 ms), and conformal catheter fixation and was validated by hydrostatic and ex vivo ...
