[Q]: Question: Are flavones from Erythrina falcata modulators of fear memory?
Answer: Our results demonstrate that vitexin, isovitexin and diosmetin-6-C-glucoside and flavonoidic fractions resulted in a significant retention of fear memory but did not prevent the extinction of fear memory. These results further substantiate that the treatment with pure flavonoids or flavanoid-rich fractions might represent potential therapeutic approaches for the treatment of neurocognitive disorders, improvement of memory acquisition and spontaneous recovery of fear.
[A]: yes


[Q]: Question: Is premature immunosenescence associated with memory dysfunction in rheumatoid arthritis?

[A]: yes


[Q]: Question: Is eGFR-TKI effective regardless of treatment timing in pulmonary adenocarcinoma with EGFR mutation?
Answer: EGFR-TKIs showed similar efficacy in patients with EGFR mutation-positive adenocarcinoma in terms of RR, PFS, and OS irrespective of treatment timing. Although EGFR-TKIs are currently the treatment of choice of first-line treatment in patients with EGFR-positive tumors, the sequential treatment with EGFR-TKI could be a reasonable option when EGFR mutation status cannot be obtained in a short time.
[A]:
yes
