Assessment of local atrial repolarization in a porcine acetylcholine model of atrial flutter and fibrillation
(2009)Objectives - Progressive electrical alternans followed by conduction block and fibrillatory conduction have been suggested to precede disorganization of atrial flutter (Afl) to atrial fibrillation (AF). The purpose of the ... -
Do β3-adrenoceptor agonists cause urinary bladder smooth muscle relaxation by inhibiting acetylcholine release?

The muscarinic antagonist gallamine induces proliferation of airway smooth muscle cells regardless of the cell phenotype
(2019)Background: Muscarinic receptor antagonists are a usual treatment for chronic airway diseases, with increased bronchoconstriction, like asthma and chronic obstructive pulmonary disease. These diseases are usually accompanied ... -
Neuromuscular Blockade in the Pre- and COVID-19 ARDS Patients
(2022)Acute respiratory distress syndrome (ARDS) accounts for a quarter of mechanically ventilated patients, while during the pandemic, it overwhelmed the capacity of intensive care units (ICUs). Lung protective ventilation (low ... -
Nicotinic cholinergic system and COVID-19: In silico evaluation of nicotinic acetylcholine receptor agonists as potential therapeutic interventions
(2021)SARS-CoV-2 infection was announced as a pandemic in March 2020. Since then, several scientists have focused on the low prevalence of smokers among hospitalized COVID-19 patients. These findings led to our hypothesis that ... -
Ranolazine-Induced Postrepolarization Refractoriness Suppresses Induction of Atrial Flutter and Fibrillation in Anesthetized Rabbits
(2013)Ranolazine (Ran) is a novel anti-ischemic agent with electrophysiologic properties mainly attributed to the inhibition of late Na+ current and atrial-selective early Na+ current. However, there are only limited data regarding ... -
Resting tension effect on airway smooth muscle: the involvement of epithelium
(2005)We studied the influence of resting tension (RT) on rabbit tracheal smooth muscle (TSM) contractions induced by acetylcholine or KCl as well as the role of epithelium and the endogenously produced nitric oxide, prostanoids ... -
The role of nitric oxide in the pathophysiology of bronchial asthma
(1998)OBJECTIVE: To study in vitro the role of nitric oxide (NO), in the pathophysiology of asthma observing the effections of a NO-donor such as sodium nitroprusside, a calcium (Ca) channel inhibitor nifedipine or neurotransmitter ... -
Skeletal muscle relaxants in anaesthesiology
(1999)During the 16th century, European explorers found that the Indians along the Amazon and Orinoco Rivers were using an arrow poison, named curare, that produced death by skeletal paralysis. Curare is one of several different ...
