[EX Q]: Question: Does production of infectious human immunodeficiency virus type 1 require depletion of APOBEC3G from virus-producing cells?
Answer: Our results suggest that Vif and APOBEC3G can be efficiently co-expressed. Thus, depletion of APOBEC3G from Vif expressing cells as suggested previously is not a universal property of Vif and thus is not imperative for the production of infectious virions.
[EX A]: no

[EX Q]: Question: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?
Answer: Pazopanib was well tolerated. Daily pazopanib eye drops in neovascular AMD subjects did not result in therapeutic benefit beyond that obtained with ranibizumab alone.
[EX A]: yes

[EX Q]: Question: Is risk perception associated with attendance at a preventive intervention for type 2 diabetes mellitus among South Asians at risk of diabetes?
Answer: Risk perception was not significantly associated with attendance. The results suggest that increasing the risk perception alone in this South Asian population is unlikely to increase the attendance at a diabetes prevention programme.
[EX A]:
no
