  • Based on the relative inhibitory effects of propranolol, the affinities of the beta receptor for hydroxybenzylpindolol and hydroxybenzylpropranolol are equivalent but are about 10 times that of pindolol or propranolol and 25-40 times that of isoproterenol. (aspetjournals.org)
  • Hearts were preconditioned with 5 min isoproterenol 0.1 μM ( 1/ 2-AR agonist), or formoterol 1 nM ( 2-AR agonist) or BRL 37344 1 μM ( 3-AR agonist) followed by 5 min reperfusion. (sun.ac.za)
  • Caspase-3 and TNF-α levels were significantly reduced at 50nM in cultured cells, a dose lower than that of a non-specific beta-adrenergic agonist, isoproterenol. (arvojournals.org)
  • stimulation
  • Mechanism of cytokine inhibition of beta-adrenergic agonist stimulation of cyclic AMP in rat cardiac myocytes. (ahajournals.org)
  • Studies conducted in our laboratory have demonstrated that activated immune cells produce a soluble inhibitor(s) of cardiac myocyte contractile and cyclic AMP (cAMP) responses to beta-adrenergic stimulation. (ahajournals.org)
  • The uncertainty was particularly great for people who might be thought to be more susceptible than most to an increase in β adrenergic stimulation from consuming the additive, such as people with cardiovascular disease or children, and that simply increasing the "uncertainty factor" built into the calculation as a safety factor would rapidly become arbitrary.

  • receptor function
  • STUDY DESIGN: beta-Receptor function (response to beta-agonist or forskolin) was tested in mononuclear leukocytes collected from women at term before or during labor. (biomedsearch.com)
  • beta-Receptor function was also tested in mononuclear leukocytes of nonlaboring patients after in vitro incubation with oxytocin (1 micromol/L), prostaglandin E2 (10 micromol/L), prostaglandin F2alpha (10 micromol/L), or buffer alone. (biomedsearch.com)
  • Drugs
  • The ban was lifted after the player successfully made the mitigating defence that there was an absence of significant negligence as the substance was not on the list of banned substances despite drugs of the same category - β2 agonists - being banned. (wikipedia.org)
  • blocker
  • Indications of administration for β agonists include: Bradycardia (slow heart rate) Asthma Chronic obstructive pulmonary disease (COPD) Heart failure Allergic reactions Hyperkalemia Beta blocker poisoning Although minor compared to those of epinephrine, beta agonists usually have mild to moderate adverse effects, which include anxiety, hypertension, increased heart rate, and insomnia. (wikipedia.org)
  • Used as adjunct to miotic or beta-blocker therapy. (medscape.com)
  • Alpha blocker Adrenergic agonist Beta-adrenergic agonist Declerck I, Himpens B, Droogmans G, Casteels R (September 1990). (wikipedia.org)
  • Pindolol, sold under the brand name Visken among others, is a beta blocker which is used in the treatment of hypertension and angina pectoris. (wikipedia.org)
  • zilpaterol
  • In 2013, zilpaterol, a β agonist sold by Merck, was temporarily withdrawn due to signs of sickness in some cattle that were fed the drug. (wikipedia.org)
  • prostaglandin
  • Is the attenuation of beta-adrenergic agonist efficacy during labor caused by elevated prostaglandin E levels? (biomedsearch.com)
  • OBJECTIVE: Our purpose was to investigate whether attenuation of beta-adrenergic agonist efficacy during labor is due to elevated prostaglandin E levels. (biomedsearch.com)
  • This effect could be induced in mononuclear leukocytes from nonlaboring women by preincubation with prostaglandin E but not oxytocin or prostaglandin F. CONCLUSIONS: Prostaglandin E induces heterologous desensitization of the beta-adrenergic receptor system in mononuclear leukocytes, comparable to that seen during labor. (biomedsearch.com)
  • We speculate that during labor the elevated levels of prostaglandin E may induce similar effects on the myometrium, thereby decreasing the efficacy of beta-agonists as tocolytics. (biomedsearch.com)
  • inhibit
  • We have previously demonstrated the ability of dobutamine (DOB), primarily a beta1AR agonist, to inhibit reductions in cancellous bone formation and mitigate disuse-induced loss of bone mass. (iupui.edu)
  • ABSTRACT
  • ENGLISH ABSTRACT: The Mechanism of -adrenergic preconditioning ( -PC) Ischaemic preconditioning (IPC), a potent endogenous protective intervention against myocardial ischaemia, is induced by exposure of the heart to repetitive short episodes of ischaemia and reperfusion. (sun.ac.za)
  • increases
  • Altogether, these data indicate that beta1AR agonist treatment during disuse mitigates negative changes in cancellous bone microarchitecture and inhibits increases in osteocyte apoptosis. (iupui.edu)
  • Combination with beta-adrenergic agonists increases the dilating effect on the bronchi. (wikipedia.org)
  • mechanism
  • However, the exact mechanism whereby activation of the - adrenergic signal transduction pathway leads to cardioprotection, is still unknown. (sun.ac.za)
  • In particular, higenamine, via a beta-adrenoceptor mechanism, induced relaxation in rat corpus cavernosum, leading to improved vasodilation and erectile function. (wikipedia.org)
  • vascular
  • It is also located on the vascular smooth muscle cells of certain blood vessels, such as those found in skin arterioles or on veins, where it sits alongside the more plentiful α1-adrenergic receptor. (wikipedia.org)
  • Chemical
  • The acquired mass spectra were compared with an in-house library (compound library and MS/MS mass spectral library) built with TraceFinder Software which contained the M/Z of the precursor ion, chemical formula, retention time, character fragment ions and the entire MS/MS spectra of 32 β-agonist standards.

  • Therefore
  • 2000). Therefore, the use of β-agonists in animal feeds has been banned in many countries such as the EU and China (Mitchell and Dunnavan, 1998 and Prezelj et al. (wikipedia.org)
  • function
  • Due to their significant nutrition redistribution function, β-agonists have been applied in the livestock industry such as pigs and ruminants to reduce carcass fat and increase muscle mass while improving growth rate and feed conversion (Bareille and Faverdin, 1996, Bergen et al. (wikipedia.org)
  • clinical
  • β3 agonists are currently in clinical research and are thought to increase the breakdown of lipids in obese patients. (wikipedia.org)
  • Beta-blockade may mask the clinical signs of continuing hyperthyroidism or complications, and give a false impression of improvement. (wikipedia.org)
