Adrenergic receptors have an important role in neural excitability and synaptic plasticity. Despite a lot of studies on these receptors, their exact role in brain disorders accompanied with hyperexcitability has not been determined. There are also controversies on their role in synaptic plasticity. In this review article, the important studies done in this regard have been reviewed to achieve a...
Background : Long-term exposure to anxiety and depression puts myocardium at risk of failure. Neurohormone Message caused be depression delivered to the heart by beta1 adrenoreceptor. The aim of this study was to survey and compare the effect of 4 weeks of endurance training with fluoxetine treatment on beta-adrenergic receptors in the male Wistar rat heart. Materials and Methods: This researc...
On most adrenergic and cholinergic nerve terminals, prejunctional α-adrenoceptors belonging to the α2-subtype have been identified. Activation of these receptors will decrease the release of norepinephrine. It has been reported that several isolated tissue preparations contain prejunctional dopamine receptors, the stimulation of which inhibits neurotransmission. It has remained uncertain whethe...
the involvement of supraspinal alpha-adrenergic receptors in tonic pain was assessed in formalin-induced pain in rats. the alpha2 adrenoceptor agonist clonidine, along with yohimbine and prazosin, α2 and α1 receptor antagonists, were introduced intracerebroventrically (icv) and/or systemically in different doses. the data show that 1) clonidine exerts an alpha adrenergic analgesic effect, in ad...
baluchi sheep is considered as the most common breed in iran, constituting about 30% of total sheep population, approximately 15 million heads. this research was designed to study the incidence of mutation in two loci of igf-i (exon 3) and adrb3 (intron) along with their association with body weight traits in baluchi sheep population. following dna extraction from 190 baluchi sheep, two pairs o...

Cancer is one of the leading causes death in world. Researchers keep attempting to develop therapy modalities decrease mortality and morbidity cancer patients by trying comprehend effect sympathetic nerves (through catecholamine adrenergic receptors) development. Catecholamine activation β-adrenergic receptors (β1-AR, β2-AR, β3-AR) may influence cytokine immunity system, initiate tumorigenesis,...
Schizophrenia is a chronic psychotic disorder characterized by the presence of symptoms (hallucinations, delusions), negative (decreased expressiveness), and cognitive (lack executive function). The exact etiology schizophrenia unknown, although it thought to be linked increased dopaminergic activity in mesolimbic neuronal pathway decreased prefrontal cortical pathway. Treatment includes both p...

Different beta 1 and 2 adrenergic receptors agonists might have 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 beta2 adrenergic receptor agonists, respectively; on body weight gain, feed conversion rate, concentration of biochemical parameters...
