Vascular Contributions to Migraine: Time to Revisit?

Frontiers in Cellular Neuroscience, 2018
Migraine is one of the most prevalent and disabling neurovascular disorders worldwide. However, despite the increase in awareness and research, the understanding of migraine pathophysiology and treatment options remain limited.

Reversible cerebral vasoconstriction syndrome [PDF]

Journal of the Neurological Sciences, 2012
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by severe headaches, as well as vasoconstriction of cerebral arteries, which resolves spontaneously in one to three months. This condition has a moderate female preponderance. The mean age of onset is around 45 years.

Limited AT1 Receptor Internalization Is a Novel Mechanism Underlying Sustained Vasoconstriction Induced by AT1 Receptor Autoantibody From Preeclampsia

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Angiotensin II type 1 receptor (AT1R) autoantibody (AT1‐AA) was first identified as a causative factor in preeclampsia. Unlike physiological ligand angiotensin II (Ang II), AT1‐AA can induce vasoconstriction in a sustained manner, causing a ...

Constrictor responses of cerebral resistance arterioles in male and female rats exposed to prenatal alcohol

Physiological Reports, 2021
While it is known that dilation of cerebral arterioles to NOS‐dependent agonists is impaired in rats exposed to prenatal alcohol, no studies have examined the influence of prenatal alcohol on constrictor response of cerebral arterioles.

Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats

Advanced Functional Materials, EarlyView.
This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.

Vasoconstriction Response to Mental Stress in Sickle Cell Disease: The Role of the Cardiac and Vascular Baroreflexes

Frontiers in Physiology, 2021
Recent studies have shown that individuals with sickle cell disease (SCD) exhibit greater vasoconstriction responses to physical autonomic stressors, such as heat pain and cold pain than normal individuals, but this is not the case for mental stress (MTS)

Reversible cerebral vasoconstriction syndrome

Journal of the Royal College of Physicians of Edinburgh, 2013
Reversible cerebral vasoconstriction syndrome (RCVS) is an underdiagnosed condition which usually presents as severe headache with or without neurological deficit. We report the case of a 55-year-old woman who presented with headache and multifocal intracerebral haemorrhage.

Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

Advanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.

CFTR deficiency aggravates Ang II induced vasoconstriction and hypertension by regulating Ca𝟐+ influx and RhoA/Rock pathway in VSMCs

Frontiers in Bioscience-Landmark, 2021
Background: Cystic fibrosis transmembrane conductance regulator (CFTR) has been associated with vascular tone and blood pressure (BP), however, its role in the genesis of hypertension remains elusive.
