(From Wikipedia, the free encyclopedia) In psychology, the Simon effect reaction times are usually faster and more accurate when the stimulus occurs in the same relative location as the response, even if the stimulus location is irrelevant to the task.

Friedreich’s ataxia (GAA)n triplex DNA structures are stabilized by Benzoquinoquinoxaline derivatives

5 FUTURE PERSPECTIVES
.../...

The experiments on (GAA)n repeat sequences described in this thesis were restricted to in vitro studies and probing of E. coli plasmid DNA. Nevertheless, the evidence that we provide for the existence of triplex structures within FA (GAA)n repeats suggests that destabilization of these structures could provide a possible therapeutic strategy for patients. Whereas BQQ stabilizes triplex structures, other DNA ligands may destabilize triplex structures. Such strategies may offer hope for developing small molecule DNA ligands to treat FA or other conditions that involve triplex DNA structures that arise from tri nucleotide repeat expansions.
