question:
Question: Does abrogation of early apoptosis alter late inhibition of hippocampal neurogenesis after irradiation?

answer:
no

question:
Question: Does transgenic Cry1Ab rice impact ecological fitness and predation of a generalist spider?
Answer: The transgenic Cry1Ab rice lines tested in this study had no adverse effects on the survival, developmental time and fecundity of P. pseudoannulata in the laboratory or on predation under field conditions. This suggests that this important predator would not be harmed if transgenic Cry1Ab rice were commercialized.
answer:
no

question:
Question: Are primary biliary cirrhosis and autoimmune cholangitis associated with coeliac disease in Crete?
Answer: We were unable to demonstrate an increased risk of coeliac disease in patients with primary biliary cirrhosis and autoimmune cholangitis. Our results confirm the previously reported high prevalence of false-positive anti-gliadin and guinea pig liver-derived anti-tissue transglutaminase antibodies in patients with chronic liver disease.
answer:
no
