the association between β2-adrenergic receptor (adrb2) -16arg/gly polymorphism (rs1042713) and chronic obstructive pulmonary disease (copd) risk has been investigated in many published studies. however, the results were inconclusive. a meta-analysis was performed to make a more precise estimation of the relationship.the pubmed, embase, isi web of science, the cochrane database of systematic rev...

Different beta 1 and 2 adrenergic receptor agonists may be various biological and physiological effects on fish species. An experiment was designed to study the effects of feeding ractopamine, terbutaline and metaproterenol; as beta1, beta2 and less selective beta 2 adrenergic receptor agonists, respectively; on body weight gain, feed conversion ratio, concentration of biochemical parameters in...

we have previously shown the adjuvant activity of propranolol (prp) (a beta-adrenergic receptor antagonist) using a vaccine model for salmonella typhimurium. in this study prp was used as an adjuvant in combination with plasmodium  berghei  (p. berghei)  whole blood stage (pwbs) antigens. balb/c mice were immunized three times with a 2-week interval, either pwbs vaccine alone or in combination ...

The β2-adrenergic receptor, located in the prostate region, binds noradrenaline and can influence growth of tumors. removal Adrb2, gene for this halt tumor thus serve as an alternative to chemotherapy cancer treatment. Inhibition receptor may have similar effects. Comparison β2- (PDB ID: 5X7D) β1-adrenergic 2Y04) structures showed a conserved binding region on Chain A offset by approximately ei...

NMR methods provide information about conformational dynamics of GPCRs over a wide range frequencies in aqueous media at near-physiological temperature, with minimal modification the wild-type GPCR covalent structures. Here we review our solution studies functionrelated GPCRs, including β2 adrenergic receptor, μ opioid and adenosine A2A receptor.

statement of the problem: various researchers have suggested the use of β2-adrenergic receptor antagonists in prevention or treatment of bone resorption. purpose: this study aimed to evaluate the effect of β2-adrenergic receptor antagonists on number of osteoclasts and osteoblasts involved in the healing of extraction socket of maxillary first molar in rats. materials and method: maxillary firs...

introduction: oxytocin is a active neuropeptide of central nervous system. in this study the effects of naloxone (opioid receptor antagonist) and yohimbine (α-2 adrenergic receptor antagonist) on analgesic effect of oxytocin applied into the locus coeruleus (lc) nucleus were investigated. methods: adult male wistar rats were used. animals divided into different groups receiving saline, oxytocin...
