Is the microvasculature tone increasing with arterial hypertension?
Alʹmanah Kliničeskoj Mediciny, 2019 Rationale: An increase in vascular tone is believed to be a major factor leading to arterial hypertension (AH). There are no means for a direct measurement of the vascular tone in clinical practice.

Opposing Roles of S1P3 Receptors in Myocardial Function
Cells, 2020 Sphingosine-1-phosphate (S1P) is a lysophospholipid mediator with diverse biological function mediated by S1P1–5 receptors. Whereas S1P was shown to protect the heart against ischemia/reperfusion (I/R) injury, other studies highlighted its ...

Physiological Reports, 2019 Upright tilt table testing has been used to test for vasovagal syncope (VVS) but can result in “false positives” in which tilt‐induced fainting (tilt+) occurs in the absence of real‐world fainting.

Increased Contractile Function of Human Saphenous Vein Grafts Harvested by “No-Touch” Technique
Frontiers in Physiology, 2018 Saphenous vein grafts are the most common conduits used for coronary artery bypass grafting (CABG); however, no more than 60% of vein grafts remain open after 10 years and graft failure is associated with poor clinical outcome.

Vasoconstriction and hyperperfusion syndrome after carotid artery stenting
The Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2022 Background Common complications of carotid artery stenting (CAS) are cerebral ischemia and hyperperfusion syndrome. To date, only a few cases of late-onset cerebral vasoconstriction occurring several hours after CAS have been reported. However, there are

Post-exercise Body Cooling: Skin Blood Flow, Venous Pooling, and Orthostatic Intolerance
Frontiers in Sports and Active Living, 2021 Athletes and certain occupations (e.g., military, firefighters) must navigate unique heat challenges as they perform physical tasks during prolonged heat stress, at times while wearing protective clothing that hinders heat dissipation.

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)

Vasoconstriction by Noradrenaline in the Brain [PDF]
Nature New Biology, 1973 IN view of the present controversy, recently voiced in your journal1–3 and elsewhere4,5, concerning a significant vasoconstrictor action of noradrenaline (NA) applied microiontophoretically in the brain, it seems worth pointing out that the required experiments, that is direct applications of NA to cerebral vessels in cats, have been performed by ...

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.
