question:
Question: Does l-Tryptophan influence acute ventilatory response at moderate altitude?
Answer: L-tryptophan does not impair ventilatory adaptation to mild hypoxia at moderate altitude.
answer:
no


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: Is non-neural tyrosine hydroxylase , via modulation of endocrine pancreatic precursors , required for normal development of beta cells in the mouse pancreas?
Answer: A non-neural catecholaminergic pathway appears to modulate the pancreatic endocrine precursor and insulin producing cell neogenesis. This finding may have important implications for approaches seeking to promote the generation of beta cells to treat diabetes.
answer:

yes
