question:
Question: Does abrogation of early apoptosis alter late inhibition of hippocampal neurogenesis after irradiation?
Answer: Early apoptotic death of neural progenitors, endothelial cells, or both does not have a causative association with late inhibition of neurogenesis after irradiation.
answer:
no


question:
Question: Does creatine supplementation affect kidney function in an animal model with pre-existing renal failure?
Answer: Creatine supplementation at a dosage of 2% w/w for 4 weeks does not impair kidney function in animals with pre-existing renal failure or in control animals.
answer:
no


question:
Question: Does adenosine-A1 receptors activation restore the suppressed cardioprotective effects of ischemic preconditioning in hyperhomocysteinemic rat hearts?
Answer: It may be concluded that the activation of adenosine-A1 receptors using CCPA markedly restored the suppressed cardioprotective and infarct size-limiting effects of IPC in hyperhomocysteinemic rat hearts. Thus, the reduced availability of extracellular adenosine and impaired activation of adenosine-A1 receptors may be responsible for abolishing the cardioprotective potential of IPC against I/R-induced myocardial injury in hyperhomocysteinemic rat hearts.
answer:

yes
