OBJECTIVE
Fat and complex carbohydrates in the distal bowel activate "brakes" inhibiting upper gut motility. The hypothesis of this study was that rapid transit carcinoid diarrhea in association with steatorrhea results in impairment of gastric emptying.
METHODS
Fifteen patients with carcinoid
Strumal carcinoid tumor of the ovary (SCTO) is a very rare kind of ovarian tumor. The symptoms of SCTO are often nonspecific and misleading. Therefore, a full understanding of the characteristics, diagnosis, and treatment methods of SCTO is important.In The immunohistochemical expression of blood-group substances and carcinoma-associated antigens were compared in rectal carcinoids and adenocarcinomas. Rectal carcinoid tumors, in contrast to rectal carcinomas, were consistently negative for CEA, gastrointestinal cancer antigen GICA (or CA 19-9), and
A patient in his 60s had undergone laparoscopic anterior resection for the treatment of carcinoma of the rectum in February 2016. Histopathologic examination revealed the lesion as a pT2(MP)n(-)M0, fStage Ⅰrectal cancer. One year post-surgery, contrast-enhanced computed tomography(CT)revealed
Galectins (Gal) are an evolutionarily conserved family of 15 carbohydrate-binding proteins (lectins) that are widely distributed in normal and neoplastic cells in a wide range of organisms. They have roles in inflammation, cell adhesion, tumor progression, and metastasis. The function and
Glucose and arginine infusion tests were performed on 12 healthy volunteers (8 males, 4 females) before and after serotoninergic activation [oral administration of L-5-hydroxytryptophan (5-HTP-) for 6 days] and serotoninergic inhibition (oral treatment with D,L-p-chloropenylalanine for 6 days).
The binding of peroxidase-conjugated Dolichos biflorus (DBA), Triticum vulgaris (WGA), Canavalia ensiformis (Con A), Arachis hypogaea (PNA), Lotus tetragonolobus, and Bandeiraea simplicifolia I (BSAI) to gastrointestinal carcinoid tumours was studied. The results indicate that carcinoid tumour cells
Small cell lung cancer (SCLC) is an aggressive form of lung cancer associated with cigarette smoking and presently accounts for approximately 20% of all lung cancer cases. SCLC cells derive from a neuroendocrine origin and therefore their antigenic profile coincides, to a great extent, with that of
BACKGROUND Primary small bowel cancer is a rare malignancy; the common histopathological types are carcinoid and adenocarcinoma. Inflammatory bowel diseases and familial adenomatous polyposis are known risk factors for small bowel cancer. Additionally, cases of surgery-induced small bowel
BACKGROUND
Gastric tumors in patients affected by neurofibromatosis type 1 are usually carcinoids or stromal tumors, and rarely adenocarcinomas.
METHODS
We report a case of an adenocarcinoma of the stomach in a 53-year-old Japanese man with neurofibromatosis type 1. An abdominal computed tomography
The most common ectopic production of a pituitary hormone is the one of ACTH leading to Cushing's syndrome. Ectopic ACTH-hypersecretion is the cause of Cushing's syndrome in 10-15% of all cases. The ACTH-secreting tumours are often oat-cell carcinomas of the lung, less frequently pancreatic cancers,
"Ectopic" proteins, not distinguished immunologically from the common alpha subunit of the human glycoprotein hormones, were purified approximately 10,000-fold from a gastric carcinoid tumor (A.L.-alpha) and from tissue culture medium of bronchogenic carcinoma cell lines (ChaGo-alpha). The purified
This study analyzed the structural differences of the carbohydrate chains of circulating free alpha-submit (alpha-SU) hypersecreted in various non-tumoral (primary hypothyroids, postmenopausal women, patients with chronic uremia, normal fetuses) and tumoral (gut carcinoids, TSH-, GH- and pure
The presence of natural carbohydrate-binding antibodies may play a role in host defence against malignant cells in addition to elicitation of an immune response by artificial carbohydrate antigens. Human serum contains immunoglobulin G(2) (IgG) fractions with selectivity to alpha- and to
