Background:Cortical dysplasias are rarely associated with vascular anomalies. They are usually associated with venous anomalies or in few cases with both arterial and venous anomalies.Methods:Twenty-six year old female presented with history of headache showed cortical dysplasia associated with pure arterial dysplasia in the absence of any associated venous anomaly.Conclusions:An abnormal arterial supply to or an abnormal venous drainage from the growing cortex may result in cortical rearrangements that eventually give rise to various neuronal migration anomalies.

The transport of proteins across the plastid envelope involves a host of proteinaceous components that attend to varying structural needs of the process. This study focuses on interactions between two select forms (designated Tic40 and Toc36) of the Tic40-related components and different structural versions of the Oee1 precursor to dissect the components' mode of operation. Interaction profiling revealed several features pertaining to how Tic40-related components might work during the transport process. The main operational features revealed are: (1) Tic40 interacts preferentially with Oee1 precursors containing only the plastid-targeting domain, (2) Toc36 interacts preferentially with Oee1 precursors containing both plastid- and thylakoid lumen-targeting domains, (3)�carboxyl truncations to either the entire Oee1 precursor or Toc36 affect interactions negatively, and (4) the general reduction of Tic40-related protein levels in transgenic plants appears to exert a greater negative impact on endogenous Oee1 levels than the other proteins assessed, a trend that corroborates the findings of the protein interaction experiments.
