background: significant elevation of cardiac biomarkers after percutaneous coronary intervention (pci) is associated with increased mortality. however, clinical importance of lesser degrees of cardiac enzyme elevation has not been well understood. multiple factors might have an etiologic role, and the incidence of myonecrosis has not changed dramatically despite pharmacological and technologica...

introduction: considering high prevalence of epileptic disease and considering that 40 percent of epileptic patients are resistant to drug therapy, it needs more researches to find new therapeutic ways. lfs is among the new methods for epilepsy treatments. one possible mechanism involved in the anticonvulsant effect of lfs is increased adenosine. therefore, in this study the role of adenosine p...

epilepsy is among the most common disorders of the central nervous system and there is not an absolute method for its treatment. it has been shown that each seizure has a depressing effect on the following seizure. thus, finding the mechanisms responsible in this phenomenon can improve our knowledge toward new ways for epilepsy treatment. in this study, the role of adenosine a1 receptors in pos...

background and objective: brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in iran. adenosine deaminase (ada) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. the aim of this study was to determine serum changes of ada and c-reactive protein (crp) levels in patients with brucellosis. ...

Background: We report the analgesic efficacy of lumbar epidural adenosine injection in reducing the chronic neuropathic pain in a patient with primitive neuroectodermal tumor. Report of the Case: In this case report a 13-year-old male with primary neuroectodermal tumor (PNET) was administered in epidural space with adenosine to reduce his pain. The patient received 10ml of 0.25% ropivacaine ...

in this study the effect of adenosine and caffeine on spontaneous activity of paragigantocellularis (pgi) neurons was investigated. the spontaneous activity of pgi neurons was significantly decreased by microinjection of adenosine (10 nm, 0.5 µl) into pgi nucleus of both control and morphine-dependent rats. the decrease in firing rate of pgi neurons of morphine-dependent rats was greater than t...

the effects of allopurinol, acyclovir and theophylline on the activity of adenosine deaminase (ada) were studied in 50 mm sodium phosphate buffer ph 7.5 at 27°c, using a uv– vis spectrophotometer. adenosine deaminase is inhibited by these ligands, via different types of inhibition. allopurinol, as a transition state analog of xanthine oxidase, and acyclovir competitively inhibit the catalytic a...

Adenine nucleotides represent crucial immunomodulators in the extracellular environment. The ectonucleotidases CD39 and CD73 are responsible for sequential catabolism of ATP to adenosine via AMP, thus promoting an anti-inflammatory milieu induced by “adenosine halo”. AMPD2 intracellularly mediates AMP deamination IMP, thereby both enhancing degradation inflammatory reducing formation adenosine....

Adenosine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [110]) are activated endogenous ligand adenosine (potentially inosine also at A3 receptors). Crystal structures for antagonist-bound [153, 313, 221, 61], agonist-bound [375, 203, 204] and G protein-bound A2A [49] have been described. The of an A1 receptor [128] adenosine-bound receptor-Gi complex [86] resolve...
