In this study the role of adenosine A1 receptors of the CA1 region of hippocampus on piriform cortex–kindled seizures was investigated in rats. Obtained results showed that in kindled animals, bilateral microinjection of N6–cyclohexyladenosine (CHA), an adenosine A1 receptor agonist, at doses of 10 and 100 mM into the hippocampal CA1 region decreased the afterdischarge duration (ADD), stage 5 s...

Background and Aims: This research aimed to study a possible link between endometriosis and polymorphism of the progesterone receptor gene. Materials and Methods: The control group consisted of 86 women without endometriosis and the case group comprised 86 patients with a diagnosis of endometriosis by laparoscopy. Genotypes for Alu insertion polymorphisms (A1/A1, A1/A2 and A2/A2) were descri...

objective: it has been suggested that low frequency stimulation (lfs) exerts its inhibitory effect on epileptogenesis through adenosine receptors activation. in the present study, effect of different lfs frequencies on a1 and a2a receptors gene expression was investigated in perforant path kindled seizures. materials and methods: animals were kindled by perforant path stimulation. afterdischarg...

Our previous study demonstrated that an extract of Cordyceps militaris (CM) derived from Samia Cynthia ricini inhibits testosterone-induced prostate hypertrophy in animal model. However, the bioactive components CM modulate function cells have not been identified and characterized. To do this, present explored effective component(s) influences viability androgen-responsive LNCaP cancer androgen...

Adenosine A1 receptors are ubiquitous mediators of presynaptic inhibition of neurotransmission in the central nervous system, yet the signalling pathway linking A1 receptor activation and decreased neurotransmitter release remains poorly resolved. We tested the contribution of c-Jun N-terminal kinase (JNK) to adenosine A1 receptor-mediated depression of field excitatory postsynaptic potentials ...

introduction: the role of adenosine a1 receptors of the entorhinal cortex on amygdaloid kindled seizures was investigated. material and methods: animals were kindled by daily electrical stimulation of amygdala. in the full kindled animals, n6-cyclohexyladenosine (cha; 0.1, 1 and 10 mm), an adenosine a1 receptor agonist, and 8-cyclopenthyle 1,3-dimethylexanthine (cpt), an adenosine a1 receptor a...

The contribution of blockade of adenosine A1 and A2A receptor to the psychostimulant effects of caffeine is still a matter of debate. When analyzing motor activity in rats, acutely administered caffeine shows a profile of a non-selective adenosine receptor antagonist, although with preferential A1 receptor antagonism. On the other hand, tolerance to the effects of A1 receptor blockade seems to ...

We describe the immunocytochemical distribution of adenosine A1 receptors in the rat hippocampus. Adenosine A1 receptor-like immunoreactivity was seen on the cell soma and dendrites of pyramidal cells and the cell soma and proximal part of dendrites of granule cells, but not on glial cells. Developmentally, adenosine A1 receptor-like immunoreactivity was diffuse on postnatal day 7 and increased...
