Fifteen consecutive patients with metastatic carcinoma who demonstrated bilateral adrenal metastasis on abdominal computed tomography (CT) were evaluated by the cosyntropin challenge test. Primary sites of tumors included lung, ten; colon, two; gastric, one; ovarian, one; and unknown primary, one. Bilateral adrenal enlargement was defined as greater than 1… (More)
During alternative splicing, the inclusion of an exon in the final mRNA molecule is determined by nuclear proteins that bind cis-regulatory sequences in a target pre-mRNA molecule. A recent study suggested that the regulatory codes of individual RNA-binding proteins may be nearly immutable between very diverse species such as mammals and insects. The model… (More)
Recent findings of extensive alternative splicing events occurring in eukaryotic organisms have provided a possible explanation for the puzzling discrepancy between the number of genes and high genome complexity. Most alternative splicing events in eukaryotic genomes are detected using sequence fragments produced by high throughput genomic technologies,… (More)
Eleven patients who had gastric bypass operations were examined with computed tomography to evaluate the status of the excluded stomach. Three of the patients had dilated excluded stomachs that accounted for the patients' symptomatology. As an upper gastrointestinal series cannot delineate the excluded stomach, computed tomography is the examination of… (More)
Metastatic masses from testicular neoplasms were evaluated with respect to their computed tomographic characteristics. They were divided in three categories: cystic, semicystic, and solid. The common denominator in the first two categories was the presence of teratomatous components. The nonteratomatous masses were solid.
