BackgroundDiminished growth hormone (GH) is associated with impaired endothelial function and fibrinolysis. GH‐releasing hormone is the primary stimulus for GH secretion and a substrate of dipeptidyl peptidase‐4.

Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

We describe a 73‐year‐old patient who presented with marked hemifacial swelling secondary to herpes zoster. Magnetic resonance imaging (MRI) revealed hyperintensity of the spinal trigeminal nucleus. In the case presented here, stimulation of the spinal trigeminal nucleus owing to herpes zoster can cause vasodilation of the facial skin.

Vasodilation increases pulse pressure variation, mimicking hypovolemic status in rabbits
OBJECTIVE: To test the hypothesis that pulse pressure respiratory variation (PPV) amplification, observed in hypovolemia, can also be observed during sodium nitroprusside (SNP)-induced vasodilation.

A mathematical model of the metabolic and perfusion effects on cortical spreading depression [PDF]
Cortical spreading depression (CSD) is a slow-moving ionic and metabolic disturbance that propagates in cortical brain tissue. In addition to massive cellular depolarization, CSD also involves significant changes in perfusion and metabolism -- aspects of CSD that had not been modeled and are important to traumatic brain injury, subarachnoid hemorrhage,

Measuring brain beats: Cardiac‐aligned fast functional magnetic resonance imaging signals
Blood and cerebrospinal fluid (CSF) pulse and flow throughout the brain, driven by the cardiac cycle. We use rapid functional magnetic resonance imaging (fMRI) measurements to assess blood and CSF flow dynamics in a conventional 3 T magnetic resonance imaging scanner.

Study of vasodilation processes
To date, the key role of endothelial dysfunction in the occurrence and progression of diabetes mellitus and diabetic retinopathy has been proven. The study was performed on white Wistar rats weighing 180-200 g.

Lipid emulsion-mediated reversal of toxic-dose aminoamide local anesthetic-induced vasodilation in isolated rat aorta [PDF]
BackgroundIntravenous lipid emulsion has been used to treat systemic toxicity of local anesthetics. The goals of this in vitro study were to determine the ability of two lipid emulsions (Intralipid® and Lipofundin® MCT/LCT) to reverse toxic dose local ...

Scalable Simulation of Realistic Volume Fraction Red Blood Cell Flows through Vascular Networks [PDF]
High-resolution blood flow simulations have potential for developing better understanding biophysical phenomena at the microscale, such as vasodilation, vasoconstriction and overall vascular resistance. To this end, we present a scalable platform for the simulation of red blood cell (RBC) flows through complex capillaries by modeling the physical ...
