In 2007, Doritos ran a campaign called Doritos X-13D Flavor Experiment where black, unidentified bags of Doritos were on the market for consumers to identify and name the flavor. The only flavor identification on these chips was All American Classic.
Sturge-Weber is an embryonal developmental anomaly resulting from errors in mesodermal and ectodermal development. Unlike other neurocutaneous disorders (phakomatoses), Sturge-Weber occurs sporadically (i.e., does not have a hereditary etiology). It is caused by a somatic activating mutation occurring in the GNAQ gene. Radiological findings will show tram track calcifications on CT, bilaterally.
Lin et al. (1993) isolated a specific dopaminergic neurotrophic protein, designated 'glial cell line-derived neurotrophic factor' (GDNF), from a rat B49 glial cell line. The corresponding cDNA was cloned from both human and rat cDNA libraries. The predicted 211-amino acid sequences of the 2 proteins showed 93% homology.
