Gastric-and-intestinal mixed endocrine cell phenotypic expression of carcinoid tumors in the rectum.
We have previously demonstrated that gastric and intestinal endocrine cell (End-cell) marker expression is important for assessment of the histogenesis of endocrine cell tumors. However, the End-cell phenotypes of carcinoid tumors in the rectum remain largely unclear. We therefore examined marker expression of rectal carcinoid tumors. We evaluated 20 rectal carcinoid tumors (as well as 8 from t...
The overall goal of this study was to estimate the prevalence of gastrointestinal (GI) parasites in dogs in the city of Villahermosa in Tabasco, Mexico. The study population consisted of 302 owned dogs that had limited access to public areas. A fecal sample was collected from each animal and examined for GI parasites by conventional macroscopic analysis and centrifugal flotation. Fecal samples ...
Identification of place of articulation in the synthesized syllables /bi/, /di/, and /gi/ was examined in three groups of listeners: (a) normal hearers, (b) subjects with high-frequency sensorineural hearing loss, and (c) normally hearing subjects listening in noise. Stimuli with an appropriate second formant (F2) transition (moving-F2 stimuli) were compared with stimuli in which F2 was constan...

The pathogenesis of gastrointestinal (GI) dysmotility in scleroderma is incompletely understood, although previous studies have proposed a neuropathic mechanism. We studied patients with scleroderma as compared with other connective tissue disease patients and normal controls for the presence of circulating antibodies to myenteric neurons. Serial dilutions of sera were overlaid on rat intestine...
BACKGROUND Caveolae are a nexus for protective signaling. Trafficking of caveolin to mitochondria is essential for adaptation to cellular stress though the trafficking mechanisms remain unknown. The authors hypothesized that G protein-coupled receptor/inhibitory G protein (Gi) activation leads to caveolin trafficking to mitochondria. METHODS Mice were exposed to isoflurane or oxygen vehicle (...
