Spreading vasodilatation in resistance arteries [PDF]

Journal of Smooth Muscle Research, 2005
Focal application of vasodilators such as acetylcholine (ACh), which evoke arterial hyperpolarization, cause coordinated dilatation along the length of an artery with minimal decay with distance from the site of application. This phenomenon is called spreading vasodilatation.

Continuous detection of cerebral vasodilatation and vasoconstriction using intracranial pulse morphological template matching. [PDF]

PLoS ONE, 2012
Although accurate and continuous assessment of cerebral vasculature status is highly desirable for managing cerebral vascular diseases, no such method exists for current clinical practice.

Long‐term adverse cardiovascular changes induced by cocoa shell extract administration through lactation in fetal undernourished and control rats

Experimental Physiology
Cocoa shell extract (CSE; rich in antioxidant compounds) administered to adult hypertensive rats exposed to fetal undernutrition (MUN) reduces blood pressure, improving cardiovascular alterations.

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS

Hepatology, EarlyView., 2022
The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.

THE MECHANISM OF ANTIDROMIC VASODILATATION [PDF]

Quarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1951
1. In the skin, in response to stimulation of the posterior root fibres, histamine is released into the venous blood. The release of histamine is paralleled by an increase in blood flow.2. In muscles, antidromic stimulation of the posterior roots does not release histamine nor increase the blood flow.3.

Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Immersing the foot in painfully-cold water evokes ipsilateral extracranial vasodilatation [PDF]

, 2012
Temporal pulse amplitude was recorded bilaterally in 56 participants before, during and after three ice-water immersions of the foot. Half of the participants were told that prolonged exposure to freezing temperatures could cause frostbite.

Whole-Body Cryotherapy Increases the Activity of Nitric Oxide Synthase in Older Men

Biomolecules, 2021
Aging causes oxidative stress, endothelial dysfunction and a reduction in the bioavailability of nitric oxide. The study aim was to determine whether, as a result of repeated whole-body exposure to cryogenic temperature (3 min −130 °C), there is an ...

Vampire Venom: Vasodilatory Mechanisms of Vampire Bat (Desmodus rotundus) Blood Feeding

Toxins, 2019
Animals that specialise in blood feeding have particular challenges in obtaining their meal, whereby they impair blood hemostasis by promoting anticoagulation and vasodilation in order to facilitate feeding. These convergent selection pressures have been
