Relationship between clinical variables and cognitive performances in migraineurs with and without aura.

Conflicting data on cognitive defects in migraine could be explained by differences in the clinical variables of the populations studied. We investigated 21 patients with migraine with aura and 24 with migraine without aura, diagnosed according to the International Headache Society criteria. The patients were submitted to a comprehensive battery of neuropsychological tests and grouped according to attack frequency and side of pain.

DNAfan: a software tool for automated extraction and analysis of user-defined sequence regions.

Summary: DNAfan (DNA Feature ANalyzer) is a tool combining sequence-filtering and pattern searching. DNAfan automatically extracts user-defined sets of sequence fragments from large sequence sets. Fragments are defined by annotated gene feature keys and co- or non-occurring patterns within the feature or close to it.
