AIMS To investigate the effects of anoxia and glucopenia (A-G) on both male and female guinea pig urinary bladder. METHODS In whole bladders superfused with oxygenated Krebs' solution, intrinsic nerves underwent electrical field stimulation (EFS) and smooth muscle stimulated with carbachol, ATP, and high potassium. The effect of 1, 2, or 3 hr A-G on the(More)
Cannabinoid CB2 receptor activation has been shown to have many pharmacological but not psychotropic effects. The aim of this study was to investigate the potential protection of brain tissues afforded by the novel substituted 4-quinolone-3-carboxylic acid derivative COR167, a selective CB2 agonist, toward ischemia and reperfusion-induced injury, as well as(More)
The aim of the present investigation was to compare mechanical responses to electrical field stimulation (EFS), as well as cholinergic and non-adrenergic, noncholinergic (NANC) neurotransmission in guinea-pig, rat, monkey and human detrusor muscle strips. Responses to EFS (0.05, 0.5 and 1 ms pulse duration, 50 V, 1-15 Hz) of guinea-pig, rat, monkey and(More)
The novel MAO-B inhibitor PF9601N, its cytochrome P450-dependent metabolite FA72 and l-deprenyl were studied as potential peroxynitrite (ONOO(-)) scavengers and nitric oxide synthase (NOS) inhibitors. The scavenging activity of these compounds was evaluated by measuring the oxygen consumption through peroxynitrite-mediated oxidation of both linoleic acid(More)
PURPOSE The selective monoamine oxidase-B (MAO-B) inhibitor, l-deprenyl, is still used for treating Parkinson's patients, however, a disadvantage of its use lies in the formation of l-amphetamine and l-methamphetamine. Subsequently, this has promoted the design of a novel, more potent, MAO-B inhibitor PF9601N, which also has neuroprotective and antioxidant(More)
The aim of this study was to investigate the effect of 17beta-oestradiol (E(2)) on detrusor smooth muscle contractility and its possible neuroprotective role against ischaemic-like condition, which could arise during overactive bladder disease. The effect of E(2) was investigated on rat detrusor muscle strips stimulated with carbachol, KCl and electrically,(More)
AIM To study the effect of 17beta-estradiol (E(2)) as a neuroprotective agent in male and female rat urinary bladders subjected to anoxia-glucopenia and reperfusion (A/G-R) damage. METHODS Rat urinary bladders were exposed to 1 hour of A-G and 2 hours of reperfusion (R). Intrinsic nerves underwent electrical field stimulation. The effect of E(2) on the(More)
There is ample evidence that ischaemia is associated with partial denervation of the detrusor muscle and that this is responsible for much of its abnormal contractile behaviour, resulting in bladder dysfunction (instability). In guinea-pig nerves are very susceptible to the ischaemic damage as compared to the muscle cells. The purpose of this study was to(More)
4-(Thiophen-2-yl)butanoic acid was identified as a cyclic substitute of the unsaturated alkyl chain of the natural ligand, capsaicin. Accordingly, a new class of amides was synthesized in good yield and high purity and their molecular recognition against the target was investigated by means of docking experiments followed by molecular dynamics simulations,(More)
Anal incontinence is a disabling condition that adversely affects the quality of life of a large number of patients, mainly with anal sphincter lesions. In a previous experimental work, in-vitro expanded bone marrow (BM)-derived mesenchymal stem cells (MSC) were demonstrated to enhance sphincter healing after injury and primary repair in a rat preclinical(More)
