background: chronic obstructive pulmonary disease (copd) is usually considered one of the leading causes of death worldwide, so finding proper therapeutic strategies for this disease is of high importance. in this meta-analysis, we reviewed the existing literature on the efficacy and safety of conventional long acting beta agonists (labas) in copd patients. methods: we searched medline and goog...

the effect of dietary terbutaline, a beta adrenergic agonist, on carcass characteristics and blood attributes in 288 japanese quails was studied from 21 through 49 days of age. dietary treatments included four levels of terbutaline [0 (t0), 1 (t1), 3 (t3), and 5 (t5) mg/kg of the diet]. quails were bled at the end of the trial for biochemical assays and the carcass characteristics were then mea...

Evaluation of Beta-Adrenergic Agonist Theophylline Function in Reducing Inflammation on Blood Metabolites and Egg Quality Traits Laying Hens at the end Production Period

Currently, the occurrence of diseases in digestive system swine has increased. Environmental stress and gastric bacteria were associated with body imbalance ulcer, which are related to pathological changes stomach. This study aimed investigate stomach histological characteristics beta-agonist free, hygienic, natural different farming methods. Three types swine’s stomachs bought from three farms...

BACKGROUND Muscarinic acetylcholine receptors (mAChRs) undergo agonist-promoted internalization, but evidence suggesting that the mechanism of internalization is beta-arrestin dependent has been contradictory and unclear. Previous studies using heterologous over-expression of wild type or dominant-negative forms of beta-arrestins have reported that agonist-promoted internalization of M2 mAChRs ...

BACKGROUND Growing evidence suggests that the Arg16Arg genotype of the beta-2 adrenergic receptor gene may be associated with adverse effects of beta-agonist therapy. We sought to examine the association of beta-agonist use and the Arg16Gly polymorphism with lung function and mortality among participants in the Atherosclerosis Risk in Communities study. METHODOLOGY AND PRINCIPAL FINDINGS We g...

BACKGROUND It has been known for many years that there are variations between asthmatic patients in terms of their perception of breathlessness during airway obstruction. STUDY OBJECTIVE To investigate the relationship between beta(2)-agonist consumption and the score of perception of dyspnea, in mild asthmatics, and the relationship between the effect of specific inspiratory muscle training ...
