and colleagues have identified a protein called Hippi as one possible mediator of Huntington disease (HD) neuronal cell death. HD begins with expansion of the polyglutamine repeats in the huntingtin protein (Htt). This frees up Hip1 protein, which normally binds to Htt. Free Hip1 can then bind to the Hippi protein identified by Nicholson, and the two proteins join in a complex with procaspase 8...
Our study was concerned with the disparity detectors underlying the initial disparity vergence responses (DVRs) that are elicited at ultrashort latencies by binocular disparities applied to large images. DVRs were elicited in humans by applying horizontal disparity to vertical square-wave gratings lacking the fundamental (termed here, the "missing fundamental"). In the frequency domain, a pure ...
The category of crossed complexes gives an algebraic model of CW -complexes and cellular maps. Free crossed resolutions of groups contain information on a presentation of the group as well as higher homological information. We relate this to the problem of calculating non-abelian extensions. We show how the strong properties of this category allow for the computation of free crossed resolutions...
