OBJECTIVE In preeclampsia, endothelium-dependent function is markedly aberrant. Myometrial resistance arteries from women with preeclampsia show a minimal, wholly nitric oxide-mediated, bradykinin-induced relaxation. Our aim was to test that phosphodiesterase 5 (PDE5) inhibition could improve endothelium-dependent function in preeclampsia. Study design(More)
There is growing concern about lack of scientific rigor and transparent reporting across many preclinical fields of biological research. Poor experimental design and lack of transparent reporting can result in conscious or unconscious experimental bias, producing results that are not replicable. The Analgesic, Anesthetic, and Addiction Clinical Trial(More)
OBJECTIVES In pre-eclampsia (PE), endothelium-dependent function of myometrial small arteries is markedly attenuated. The residual PE response is wholly NO mediated. We have previously demonstrated that PDE5 inhibition can improve endothelial function in myometrial small arteries from women with PE. We aimed to assess whether the effect of PDE5 inhibition(More)
Burrowing, an ethologically relevant rodent behaviour, has been proposed as a novel outcome measure to assess the global impact of pain in rats. In a prospective multicentre study using male rats (Wistar, Sprague-Dawley), replication of suppressed burrowing behaviour in the complete Freund adjuvant (CFA)-induced model of inflammatory pain (unilateral, 1(More)
A novel tertiary amine series of potent muscarinic M(3) receptor antagonists are described that exhibit potential as inhaled long-acting bronchodilators for the treatment of chronic obstructive pulmonary disease. Geminal dimethyl functionality present in this series of compounds confers very long dissociative half-life (slow off-rate) from the M(3) receptor(More)
The exposure of the skin to Ultraviolet (UV) irradiation results in a classical inflammatory reaction characterised by both erythema (flare) and hypersensitivity to noxious and non noxious stimuli (i.e. hyperalgesia and allodynia). No spontaneous pain is associated to this injury [1,2]. Cutaneous UV irradiation causes DNA damage, activates MAP kinase in(More)
