Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

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 the absolute nucleated red blood cell ( aNRBC ) count at birth an indicator for retinopathy of prematurity ( ROP )?
Answer: We are unable to support the previously reported relationship of aNRBCs with ROP. Our population was three times larger, had higher aNRBCs and less retinopathy than previously reported. A biological principle of cause and effect or predisposition to ROP as reflected by aNRBCs should have been easier for us to demonstrate, if it existed.

A: no

Q: Question: Does intrathecal synthesis of anti-Hu antibodies distinguish patients with paraneoplastic peripheral neuropathy and encephalitis?
Answer: In conclusion, our results indicate that patients even with one defined antineuronal antibody need to be regarded separately depending on the involved location of the nervous system. We recommend incorporation of anti-Hu analyses in the CSF and calculating the intrathecal synthesis in patients with anti-Hu syndrome.

A:
yes
