question:
Question: Is reorganization of Azospirillum brasilense cell membrane mediated by lipid composition adjustment to maintain optimal fluidity during water deficit?
Answer: Azospirillum brasilense is able to perceive osmotic changes by changing the membrane fluidity. This effect is offset by changes in the composition of membrane phospholipid and FA, contributing to the homeostasis of membrane fluidity under water deficit.
answer:
yes


question:
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.
answer:
no


question:
Question: Does ski diminish TGF-β1-induced myofibroblast phenotype via up-regulating Meox2 expression?
Answer: Ski diminishes the myofibroblast phenotype induced by TGF-β1 through the suppression of Zeb2 by up-regulating the expression of Meox2.
answer:

yes
