• 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)
  • Isoproterenol
  • 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)
  • 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  • In 2013, zilpaterol, a β agonist sold by Merck, was temporarily withdrawn due to signs of sickness in some cattle that were fed the drug.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)
  • inhibition
  • The relief of inhibition on Ca++-ATPase leads to faster Ca++ uptake into the sarcoplasmic reticulum, thereby contributing to the lusitropic response elicited in heart by beta-agonists. (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. (wikipedia.org)
  • 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
  • In general, pure beta-adrenergic agonists have the opposite function of beta blockers. (wikipedia.org)
  • 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)
  • α Adrenergic agonists have the opposite function of alpha blockers. (wikipedia.org)
  • In particular, higenamine, via a beta-adrenoceptor mechanism, induced relaxation in rat corpus cavernosum, leading to improved vasodilation and erectile function. (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)
  • action
  • Increase outflow of aqueous humor through trabecular meshwork and possibly through uveoscleral outflow pathway, probably by a beta2-agonist action. (medscape.com)
