The equine aortic valve is subject to non-inflammatory degenerative changes, associated with aortic valvular regurgitation (AR). This disease shares pathological and epidemiological features with AR in humans, and may serve as a useful model to study in-vitro functional responses associated

Thromboxane A2 synthase (TXAS) binds to the endoplasmic reticulum membrane and catalyzes both an isomerization of prostaglandin H2 (PGH2) to form thromboxane A2 (TXA2) and a fragmentation of PGH2 to form 12-hydroxy-5,8,10-heptadecatrienoic acid (HHT) and malondialdehyde (MDA). TXAS is a

Nonadrenergic noncholinergic (NANC) vasodilator mechanisms may contribute to the maintenance of low vascular resistance characteristic of the pulmonary circulation. Previous studies have demonstrated that nitric oxide (NO) is the principal NANC neurotransmitter in guinea pig pulmonary arteries. We examined whether

1. 5-Hydroxytryptamine (5-HT) exerts both contractile and relaxant effects in the marmoset isolated aorta, actions that are unaffected by the 5-HT2 antagonist ketanserin. The aim of the present study was to define the receptors mediating the contractile activity of 5-HT

1 The walls of certain large blood vessels are nourished by the vasa vasorum, a network of microvessels that penetrate the adventitia and media of the vessel wall. The purpose of this study was to characterize endothelin-1 (ET-1)-mediated contraction of
