[Q]: Question: Is tumor invasion depth a useful pathologic assessment for predicting outcomes in cervical squamous cell carcinoma after neoadjuvant radiotherapy?

[A]: yes

[Q]: Question: Does long-term treadmill exercise attenuate tau pathology in P301S tau transgenic mice?
Answer: Our results suggest that forced treadmill exercise differently affects the brain and spinal cord of aged P301S tau mice, with greater benefits observed in the spinal cord versus the brain. Our work adds to the growing body of evidence that exercise is beneficial in tauopathy, however these benefits may be more limited at later stages of disease.
[A]: yes

[Q]: Question: Is meis2 essential for cranial and cardiac neural crest development?
Answer: Meis2-null mice are embryonic lethal. Our results reveal a critical role of Meis2 during cranial and cardiac neural crest cells development in mouse.
