Input: Consider Input: Question: Do interictal epileptiform discharges have an independent association with cognitive impairment in children with lesional epilepsy?
Answer: Overall, IED effects on cognition were of a magnitude similar to lesional influences or drug effects (topiramate use). This study demonstrates an association between IEDs and cognitive dysfunction, independent of the underlying focal brain pathology.

Output: yes


Input: Consider Input: Question: Do natural triterpenic diols promote apoptosis in astrocytoma cells through ROS-mediated mitochondrial depolarization and JNK activation?
Answer: Overall, we provide a significant insight into the anticarcinogenic action of erythrodiol and uvaol that may have a potential in prevention and treatment of brain tumors and other cancers.

Output: yes


Input: Consider Input: Question: Is dystrophic epidermolysis bullosa pruriginosa associated with frequent FLG gene mutations?
Answer: DEB-Pr develops as a result of COL7A1 gene mutations and acquired phenotype-modifying factors. Filaggrin mutations did not contribute to the pruriginous phenotype in the present patient cohort.


Output: no
