elevated amounts of free radicals due to ionizing radiation have damaging effects on the body. h2-receptor antagonists have potential oxygen radical scavenging properties. we tried to determine the effects of two h2-receptor antagonists (cimetidine and ranitidine) on lipid peroxidation (lpo) and lipid profile (lp) in plasma and liver of γ-irradiated (1gy/day for 3 days) balb/c mice. the control...

conclusions this case showed the effect of additional anakinra on children with fmf who were colchicine resistant. case presentation herein was reported a colchicine non-responsive patient with accurate diagnosis and early treatment of fmf. she had presented with recurrent and persistent acute abdominal pain attacks and several abdominal surgeries. addition of recombinant interleukin-1 receptor...

background: polycystic ovarian syndrome (pcos) patients are prone to premature lh surge and ovarian hyperstimulation syndrome (ohss). long gnrh analogue protocol and gnrh antagonist protocol are two methods utilized for induction ovulation in patients undergoing ivf/icsi. objective: the aim of this study was to compare the effects of gnrh agonists and antagonists in pcos patients. materials and...

Adenosine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [112]) are activated endogenous ligand adenosine (potentially inosine also at A3 receptors). Crystal structures for antagonist-bound [155, 316, 224, 62], agonist-bound [379, 205, 206] and G protein-bound A2A [49] have been described. The of an A1 receptor [130] adenosine-bound receptor-Gi complex [87] resolve...

Arginine-phenylalanine-amide (RFamide)-related peptides known as neuropeptide VF (NPVF) have a crucial role in feeding regulation. The present study purposed to determine the effect of intracerebroventricular (ICV) injection NPVF on dietary intake and possible interactions with glutamate opioid systems broiler chicken. In experiment 1, chickens received ICV administration control solution, (16 ...

Objective Coasting can reduce the ovarian hyperstimulation syndrome (OHSS) risk in ovulation induction cycles before intracytoplasmic sperm injection (ICSI). This study aimed to investigate the effect of gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols to controlled ovarian hyperstimulation (COH) cycles with coasting on the parameters of ICSI cycles and the outcome. M...

BACKGROUND: Brain monoamines (such as histamine and dopamine) play an important role in emotions, cognition, reward and feeding behavior. The interactions between histamine and dopamine were studied in many physiological functions but this correlation is unclear in feeding behavior of chickens. The aim of this study was to investigate the interaction of central histaminergic and dopaminergic sy...

We investigated the effect of W-7, a calmodulin inhibitor, on voltage-dependent K(+) (Kv) channels in freshly isolated coronary arterial smooth muscle cells using the whole-cell patch clamp technique. The amplitude of Kv currents was inhibited by W-7 in a concentration-dependent manner, with an IC50 value of 3.38±0.47μM and a Hill coefficient of 0.84±0.10. W-7 shifted the activation curve to a ...

Objective(s): Oxytocin is involved in modulation of many brain-mediated functions. In the present study, we investigated the central effects of oxytocin and its receptor antagonist, atosiban on inflammatory pain. The contribution of opiate receptors was explored using non-selective and selective antagonists. Materials and Methods: The fourth ventricle of the brain of anesthetized rats was impla...

Introduction: Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) i...
