PURPOSE The objective of this study was to examine the clincopathologic characteristics and outcomes of familial adenomatous polyposis (FAP) patients with and without desmoid tumors (DTs), including the risk factors for progression of FAP-related DTs. MATERIALS AND METHODS We reviewed the medical records and database of all patients with FAP who were treated between January 1993 and December ...
BACKGROUND Hepatoblastoma is a rare, rapidly progressive, usually fatal childhood malignancy, which if confined to the liver can be cured by radical surgical resection. An association between hepatoblastoma and familial adenomatous polyposis (FAP), which is due to germline mutation of the APC (adenomatous polyposis coli) gene, has been confirmed, but correlation with site of APC mutation has no...
The protease fibroblast activation protein (FAP) is a specific marker of activated mesenchymal cells in tumour stroma and fibrotic liver. A specific, reliable FAP enzyme assay has been lacking. FAP's unique and restricted cleavage of the post proline bond was exploited to generate a new specific substrate to quantify FAP enzyme activity. This sensitive assay detected no FAP activity in any tiss...
Apatite (Ap) dissolution in diluted acids is well described the literature, but technological processes which use more concentrated acids, reaction fast, and it complicated to follow process kinetics. The relationship between pH change apatite rate depending on HCl concentration was studied by thermodynamic calculations experiments with synthetic fluorapatite (FAp). On basis of experimental mea...
INTRODUCTION Gastrointestinal symptoms are common among patients with transthyretin familial amyloid polyneuropathy (TTR-FAP). This post hoc analysis evaluated the nutritional status of TTR-FAP patients treated with tafamidis while enrolled in clinical trials. METHODS Nutritional status was measured by the modified body mass index (mBMI = BMI × albumin level). Treatment-related changes in mBM...
The diprotonated form of a fluorinated free base porphyrin, namely 5-(p-aminophenyl)-10,15,20-tris(pentafluorophenyl)porphyrin (H(2)FAP), can catalyze the reduction of oxygen by a weak electron donor, namely ferrocene (Fc). At a water/1,2-dichloroethane interface, the interfacial formation of H(4)FAP(2+) is observed by UV-vis spectroscopy and ion-transfer voltammetry, due to the double protonat...
BACKGROUND/AIMS Conventional histopathology, leucocyte typing, cytokine mRNA expression, and crypt cell turnover were compared in ileal pouch biopsy specimens from patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). METHODS Biopsy specimens were taken from 17 patients with UC and seven with FAP at a median interval of 19 months (range 2-120) after ileostomy closure...
Desmoid tumors (DTs), the commonest extra-intestinal manifestation of familial adenomatosis polyposis (FAP), are monoclonal neoplasms demonstrating fibroblastic - myofibroblastic differentiation; they are locally invasive without metastatic capacity. FAP-associated DT natural history knowledge is limited; we examined patient and tumor characteristics for a FAP-DT cohort and evaluated anti-DT th...
BACKGROUND Fibroblast activation protein (FAP) is a type II membrane protein expressed on tumor stroma fibroblasts in more than 90% of all carcinomas. FAP serves as a diagnostic marker and is potential therapeutic target for treatment of a wide variety of FAP+ carcinomas. Murine tumor stroma models and FAP-specific antibodies are required to investigate the functional role of FAP in tumor biolo...
familial adenomatous polyposis (fap) is a hereditary autosomal dominant cancer syndrome, results from germ line mutation or deletion of the adenomatous polyposis coli (apc) gene on chromosome 5q21. patients with fap suffer from multiple polyps mainly at the colorectal region as well as other parts of the gastrointestinal tract, which has propensity to transform into carcinoma. fap has also been...
