Nucleotide sequence of the Xdh region in Drosophila pseudoobscura and an analysis of the evolution of synonymous codons.

The nucleotide sequence of the Xdh region of Drosophila pseudoobscura is presented. The Xdh gene structure and organization are compared with the homologous region in D. melanogaster.

Sequence of the structural gene for xanthine dehydrogenase (rosy locus) in Drosophila melanogaster.

We determined the nucleotide sequence of a 4.6-kb EcoRI fragment containing 70% of the rosy locus. In combination with information on the 5' sequence, the gene has been sequenced in entirety.

Ménière disease and cerebral impairment.

A recent series of findings based on psychological test patterns suggests that the behavioral disturbance seen in Ménière disease is, in many instances, predicated on organic cerebral impairment. If this proves to be the case, an important source would have been uncovered that could account for some of the behavioral difficulties associated with Ménière disease. The present study challenges the previous reports, suggesting that these findings emerged because of imprecise methodologic procedures.
