The role of potassium channels in the endothelial dysfunction induced by periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Objective: Periodontitis is associated with endothelial dysfunction, which is clinically characterized by a reduction in endothelium-dependent relaxation. However, we have previously shown that impairment in endothelium-dependent relaxation is transient. Therefore, we evaluated which mediators ...

Acetylcholine produces contractions mediated by the cyclooxygenase pathway in arterial vessels in the Chilean frog (Calyptocephalella gayi)

Braz. j. biol; 77 (4), 2017
Abstract Previous studies performed in marine fish (I. conceptionis and G. laevifrons) showed that indomethacin blocked arterial contraction mediated by acetylcholine (ACh). The objective of this study was to determine if contraction induced by acetylcholine is mediated by the cyclooxygenase pathway in s...

Acetylcholine chloride 1% usage for intraoperative cataract surgery miosis

Rev. bras. oftalmol; 76 (5), 2017
Abstract Objective: To test the efficacy of Acetylcholine chloride use in obtaining intraoperative miosis on phacoemulsification cataract surgery. Methods: Patients with cataract diagnosis and elected for surgical phacoemulsification procedure were selected. All patients underwent conventional phacoemu...

Effects of Continuous and Accumulated Exercise on Endothelial Function in Rat Aorta

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. Objective: to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Metho...

A Single Resistance Exercise Session Improves Aortic Endothelial Function in Hypertensive Rats

Arq. bras. cardiol; 108 (3), 2017
Abstract Background: Physical exercise is an important tool for the improvement of endothelial function. Objective: To assess the effects of acute dynamic resistance exercise on the endothelial function of spontaneously hypertensive rats (SHR). Methods: Ten minutes after exercise, the aorta was remove...

Role of NO in arterial vascular function of intertidal fish (Girella laevifrons) and marine fish (Isacia conceptionis)

Braz. j. biol; 76 (2), 2016
Abstract Previous studies performed in intertidal fish (Girella laevifrons),as well as marine fish (Isacia conceptionis), showed that acetylcholine (ACh) produced contractions mediated by cyclooxygenases that were dependent on the area and potency of contraction in several arterial vessels. Given that th...

Expression of non-neuronal cholinergic system in maxilla of rat in vivo

Biol. Res; 47 (), 2014
BACKGROUND: Acetylcholine (ACh) is known to be a key neurotransmitter in the central and peripheral nervous systems, which is also produced in a variety of non-neuronal tissues and cell. The existence of ACh in maxilla in vivo and potential regulation role for osteogenesis need further study. RESULTS: Co...

Reporte de dos casos de miastenia gravis en el embarazo

Rev. Nac. (Itauguá); 4 (2), 2012
La miastenia gravis es un trastorno autoinmune de la trasmisión neuromuscular que involucra la producción de autoanticuerpos dirigidos contra receptores músculo-esqueléticos, en la gran mayoría de los casos de acetilcolina. El curso de la miastenia gravis en el embarazo es impredecible. Pueden regis...
