Dipeptidyl Peptidase‐4 Inhibition Potentiates Stimulated Growth Hormone Secretion and Vasodilation in Women

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
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.

Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

open access: yesCatheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022
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 ...

Cardiovascular and hemodynamic consequences of recombinant placental growth factor administration in Guinea pigs

open access: yesHypertension in Pregnancy, 2022
Placental growth factor (PlGF), a member of the vascular endothelial growth factor family of proteins regulating angiogenesis, has been shown to have acute vasodilatory effects on human resistance arteries.

Involvement of the spinal trigeminal nucleus secondary to herpes zoster in a patient with hemifacial redness and swelling

open access: yesJournal of Cutaneous Immunology and Allergy, Volume 5, Issue 6, Page 238-239, December 2022., 2022
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

open access: yesClinics, 2010
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]

open access: yesPLoS ONE 8(8) (2013), 2012
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

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 280-294, January 2023., 2023
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

open access: yesJournal of Education, Health and Sport, 2019
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]

open access: yesKorean Journal of Anesthesiology, 2013
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]

open access: yes, 2019
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 ...
