Q: Question: Does the Drosophila Chmp1 protein determine wing cell fate through regulation of epidermal growth factor receptor signaling?
Answer: Drosophila Chmp1 negatively regulates DER signaling, likely through its role in MVB formation. Loss of Chmp1 activity in the Drosophila wing induces a cell fate change from intervein to vein that should provide a useful tool for future studies of ESCRT protein activity.

A: yes

Q: Question: Does oesophageal pH monitoring in infants : elimination of gastric buffering modify reflux index?
Answer: Overall the data do not support a benefit from including periods of gastric buffering in the routine analysis of oesophageal pH monitoring data. Therefore standard oesophageal pH monitoring should be with a single electrode and should not include periods of gastric buffering.

A:
no
