We tested whether the adenosine A1 receptor agonist, R-PIA, suppressed torsade de pointes (TdP) induced by the delayed rectifier potassium channel blocker clofilium. Furthermore, we studied the underlying mechanism: beta-adrenergic antagonism or ATP-sensitive K+ channel (IK-ATP) opening. In anesthetized rabbits

1. It is reported that alpha1-receptors and adenosine A1-receptors are involved in the ischaemic preconditioning (PC) effect on infarct size (IS). However, it is still unclear to what extent alpha1-receptors and adenosine A1-receptors contribute to the mechanism of PC. Therefore

Adenosine is a major negative neuromodulator of synaptic activity in the central nervous system and can exert anticonvulsant and neuroprotective effects in many experimental models of epilepsy. Extracellular adenosine can be formed by a membrane-anchored enzyme ecto-5'-nucleotidase. The purposes of

Adipocyte triglyceride storage provides a reservoir of energy that allows the organism to survive times of nutrient scarcity, but excessive adiposity has emerged as a health problem in many areas of the world. Monoacylglycerol acyltransferase (MGAT) acylates monoacylglycerol to produce

We examined the antiallodynic interaction between gabapentin and adenosine A1 receptor agonist, N(6)-(2-phenylisopropyl)-adenosine R-(-)isomer (R-PIA), in a rat model of nerve ligation injury. Rats were prepared with ligation of left L5-6 spinal nerves and intrathecal catheter implantation for drug administration.
