Cholesterol and docosahexaenoic acid likely protect against alcohol-induced constriction of cerebral arteries via a common pathway

Advances in Drug and Alcohol Research
Binge alcohol drinking is significantly associated with an increased risk of cerebrovascular dysfunction. Within cerebral artery smooth muscle, alcohol inhibits calcium- and voltage-gated potassium (BK) channels of large-conductance, leading to ...

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...

Effect of Phenylephrine on Cerebrovascular Regulation: A Translational Perspective

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Phenylephrine is an alpha 1‐adrenergic receptor (α1R) agonist. Evidence indicates activation of α1Rs can initiate both vasoconstrictor and dilator signaling. How phenylephrine affects cerebrovascular regulation remains unclear.
