Nine lethal complementation groups flanking the Drosophila Dopa decarboxylase (Ddc) gene, have been localized within 100 kb of cloned chromosomal DNA. Six of these complementation groups are within 23 kb of DNA, and all ten complementation groups, including Ddc, lie within 78-82 kb of DNA. The potential significance of this unusually high gene density is(More)
BACKGROUND Endoscopic ultrasound (EUS) is useful for detecting depth of invasion and nodal involvement in patients with early Barrett's neoplasia (EBN), precluding endoscopic management. This study aimed to determine whether the lesion morphology of the EBN shown on high-resolution endoscopy predicts EUS and histologic tumor stage. METHODS Retrospective(More)
Determination of the effects of presenilin 1 (PSEN1) mutations, involved in autosomal dominant early-onset Alzheimer's disease (ADEOAD), on the interaction between PSEN1 and binding proteins is essential to determine which interactions are involved in Alzheimer's disease (AD) pathogenesis. The PSEN1 binding protein glycogen synthase kinase-3 beta (GSK-3(More)
An in silico approach was used to investigate cytochrome c and the cytochrome c gene of Phanerochaete chrysosporium. The cytochrome c gene contains four introns. Omission of the introns reveals a DNA sequence coding for a complete predicted amino acid sequence for P. chrysosporium cytochrome c consistent with those of other cytochromes c. Fungal cytochromes(More)
