In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: Evidence of attack-related cognitive dysfunction in migraine is growing. Controversy exists on whether cognitive dysfunction, mainly executive, may persist between attacks. Measuring the impact of cognitive function is gaining importance in clinical and research settings in migraine.', 'To compare the performance of interictal migraine patients to controls in an assembled neuropsychological battery focused on executive functions and to study the practice effect of its repeated applications.', 'Assembly of the battery that was then applied twice within 6\xa0weeks to interictal migraineurs and matched healthy controls.', 'Migraine patients (n\xa0=\xa024) and controls (n\xa0=\xa024) had similar performance in both applications of the battery. There was a slight practice effect between the first and second evaluation, significant in Stroop Interference test (P\xa0=\xa00.002, multiplicity corrected); a meaningful score change was determined for each raw test scores.\Question: Is sequential brief neuropsychological evaluation of migraineurs identical to controls?
[A]: Interictal migraineurs and controls performance is identical in a brief cognitive battery focused on executive functions. Repeated applications produced a practice effect that was quantified.


[Q]: Context: Lung cancer is the most important cause of cancer mortality worldwide, but the underlying mechanisms of this disease are not fully understood. Copy number variations (CNVs) are promising genetic variations to study because of their potential effects on cancer.', 'Here we conducted a pilot study in which we systematically analyzed the association of CNVs in two lung cancer datasets: the Environment And Genetics in Lung cancer Etiology (EAGLE) and the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial datasets. We used a preestablished association method to test the datasets separately and conducted a combined analysis to test the association accordance between the two datasets. Finally, we identified 167 risk SNP loci and 22 CNVs associated with lung cancer and linked them with recombination hotspots. Functional annotation and biological relevance analyses implied that some of our predicted risk loci were supported by other studies and might be potential candidate loci for lung cancer studies.\Question: Does combined analysis with copy number variation identify risk loci in lung cancer?
[A]: Our results further emphasized the importance of copy number variations in cancer and might be a valuable complement to current genome-wide association studies on cancer.


[Q]: Context: In the fruit fly Drosophila, the Inscuteable protein localises to the apical cell cortex in neuroblasts and directs both the apical-basal orientation of the mitotic spindle and the basal localisation of the protein determinants Numb and Prospero during mitosis. Asymmetric localisation of Inscuteable is initiated during neuroblast delamination by direct binding to Bazooka, an apically localised protein that contains protein-interaction motifs known as PDZ domains. How apically localised Inscuteable directs asymmetric cell divisions is unclear.', 'A novel 70 kDa protein called Partner of Inscuteable (Pins) and a heterotrimeric G-protein alpha subunit were found to bind specifically to the functional domain of Inscuteable in vivo. The predicted sequence of Pins contained tetratrico-peptide repeats (TPRs) and motifs implicated in binding Galpha proteins. Pins colocalised with Inscuteable at the apical cell cortex in interphase and mitotic neuroblasts. Asymmetric localisation of Pins required both Inscuteable and Bazooka. In epithelial cells, which do not express inscuteable, Pins was not apically localised but could be recruited to the apical cortex by ectopic expression of Inscuteable. In pins mutants, these epithelial cells were not affected, but neuroblasts showed defects in the orientation of their mitotic spindle and the basal asymmetric localisation of Numb and Miranda during metaphase. Although localisation of Inscuteable in pins mutants was initiated correctly during neuroblast delamination, Inscuteable became homogeneously distributed in the cytoplasm during mitosis.\Question: Does a protein complex containing Inscuteable and the Galpha-binding protein Pins orient asymmetric cell divisions in Drosophila?
[A]:
Pins and Inscuteable are dependent on each other for asymmetric localisation in delaminated neuroblasts. The binding of Pins to Galpha protein offers the intriguing possibility that Inscuteable and Pins might orient asymmetric cell divisions by localising or locally modulating a heterotrimeric G-protein signalling cascade at the apical cell cortex.
