Thromboxane synthase is a hemethiolate enzyme that catalyzes the isomerization of prostaglandin H2 to thromboxane A2. We report the first resonance Raman (RR) spectra of recombinant human thromboxane synthase (TXAS) in both the presence and the absence of substrate analogues

Isolated vessels from four elasmobranchs, yellow stingray (Urolophus jamaicensis), clearnose skate (Raja eglanteria), ghost shark (Hydrolagus novaezelandiae), and spiny dogfish (Squalus acanthias), were examined for the presence of spontaneous contractions (SC). SC were observed in otherwise unstimulated dorsal aortas (DA)
The pathogenesis of pulmonary hypertension remains incompletely understood. Many factors have been implicated; however, there has been great interest in the potent pulmonary vasoconstrictor serotonin (5-HT) due to episodes of primary pulmonary hypertension in humans triggered by serotoninergic appetite-suppressant drugs.
Preliminary data suggest that K(ATP) channels may be expressed in placental arteries and veins [Wareing M, Turner C, Greenwood SL, Baker PN, Fyfe GK. Expression of mRNA encoding K+ channels in chorionic plate arteries and veins. J Soc Gynecol Investig
Because sulfonylureas, such as glibenclamide, are used to treat Type 2 diabetes and because this disease is associated with various cardiovascular complications that may be mediated by thromboxane (TX), this study was designed to characterize the role of glibenclamide on
