D. russelii Venom Mediates Vasodilatation of Resistance Like Arteries via Activation of K_v and K_Ca Channels

Toxins, 2019
Russell’s viper (Daboia russelii) venom causes a range of clinical effects in humans. Hypotension is an uncommon but severe complication of Russell’s viper envenoming. The mechanism(s) responsible for this effect are unclear.

EXPERIMENTS ON ATROPINE-RESISTANT VASODILATATION IN SALIVARY GLANDS [PDF]

, 1963
Vasodilatation induced by stimulation of the parasympathetic nerve supply to the submaxillary and the parotid glands has long been known to be resistant to the blocking effect of atropine.

Vasorelaxation, Induced by Dictyota pulchella (Dictyotaceae), a Brown Alga, Is Mediated via Inhibition of Calcium Influx in Rats

Marine Drugs, 2011
This study aimed to investigate the cardiovascular effects elicited by Dictyota pulchella, a brown alga, using in vivo and in vitro approaches. In normotensive conscious rats, CH2Cl2/MeOH Extract (CME, 5, 10, 20 and 40 mg/kg) from Dictyota pulchella ...

Antihistamine-sensitive active vasodilatation in the perfused hindquarters of the rat [PDF]

, 1986
The innervated, constant flow perfused hindquarters of the rat have been used to evaluate post-stimulation vasodilatation, which is a model of active reflex vasodilatation in this species.

The Clinical Significance of Salusins in Systemic Sclerosis—A Cross-Sectional Study

Diagnostics, 2023
Background: Systemic sclerosis (SSc) is a connective tissue disease manifesting with progressive fibrosis of the skin and internal organs. Its pathogenesis is strictly associated with vascular disfunction and damage.

Regulation of the Muscarinic M3 Receptor by Myocardin-Related Transcription Factors

Frontiers in Physiology, 2021
Myocardin-related transcription factors (MRTFs: myocardin/MYOCD, MRTF-A/MRTFA, and MRTF-B/MRTFB) are co-factors of serum response factor (SRF) that activate the smooth muscle cell (SMC) gene program and that play roles in cardiovascular development and ...

A reactive oxygen species-mediated component in neurogenic vasodilatation [PDF]

, 2008
Aims: Activation of the transient receptor potential vanilloid receptor 1 (TRPV1) leads to release of potent microvascular vasodilator neuropeptides.

Have we missed that neural vasodilator mechanisms may contribute to exercise hyperemia at onset of voluntary exercise?

Frontiers in Physiology, 2013
Whether neurally mediated vasodilatation may contribute to exercise hyperemia has not been completely understood. Bülbring and Burn (1935) found for the first time the existence of sympathetic cholinergic nerve to skeletal muscle contributing to ...

Cooling‐induced cutaneous vasodilatation is mediated by small‐conductance, calcium‐activated potassium channels in tail arteries from male mice

Physiological Reports, 2023
Cooling causes cutaneous dilatation to restrain cold‐induced constriction and prevent tissue injury. Cooling increases communication through myoendothelial gap junctions (MEGJs), thereby increasing endothelium‐derived hyperpolarization (EDH)‐type ...

Insulin Resistance and Pellino-1 Mediated Decrease in the Activities of Vasodilator Signaling Contributes to Sunitinib-Induced Hypertension

Frontiers in Pharmacology, 2021
Antiangiogenic tyrosine kinases inhibitors induce hypertension, which may increase the incidents of cardiovascular complications and limit their use. However, the mechanisms by which usage of TKIs results in hypertension have not been fully understood ...
