[EX Q]: Question: Do the Histologic Classifications of Lung Adenocarcinomas Are Discriminable by Unique Lineage Backgrounds?
Answer: For the first time, we showed the unique lineage backgrounds of different histologic subtypes and oncogenic mutations. Assessing this added parameter might be beneficial in discriminating intertumor heterogeneity, advancing target exploration, developing theranostic/prognostic biomarkers, and designing clinical trials.
[EX A]: yes

[EX Q]: Question: Does metal debris concentrations in soft tissues adjacent to loosened femoral stem is higher in uncemented than cemented implants?
Answer: In soft tissue around a loosened stem, the concentrations of metal ions from implants are much higher in case of uncemented stems than of cemented ones. Metal ions from vitalium femoral heads were found around uncemented stems in similar values to cemented streams.
[EX A]:
yes
