this report describes the histological and immunohistochemical features of a small intestinal tumor that resembled a human gastrointestinal stromal tumor (gists) in a seven-year-old male cross-breed dog. this was unique because of the expression of desmin by the tumor. grossly, the white-gray tumor measured 8.0 × 4.0 × 6.5 cm and was 760 gram in weight. it was cystic and enveloped the jejunum. ...

cystic hydatid disease (hydatidosis) is the most serious tape-worm infection prevalent in the cattle and sheep raising area of the world. hydatidosis in man (as an accidental host) caused by infection with the ova containing larval stage of echinococcus spp. in the last decade different techniques have been employed for the serological diagnosis of hydatid disease, such as iha, ifa, elisa, ccle...

introduction: radiolabeled antibiotics are being used for the specific diagnosis of infection by exploiting their specific binding properties to the bacterial components, thereby making it possible to differentiate infection from sterile lesions. the aim of this work was to prepare and evaluate a freeze-dried kit of ciprofloxacin designed for the labeling with 99mtc. methods: factors like amou...

background: melanoma causes the greatest morbidity and mortality of all skin cancers. mucosal melanoma is a rare but highly aggressive neoplasm. according to previous studies the prevalence of kit mutations in acrallentiginous and mucosal melanomas is relatively low (less than 15–20%), but it can have profound therapeutic implications for localized high risk or metastatic diseases. our goal was...

introduction: ubiquicidin 29-41 (ubi) is a fragment of the cationic antimicrobial peptide that is present in various species including humans. the purpose of this study was to investigate radiochemical and biological characteristics of [6-hydrazinopyridine-3-carboxylic acid (hynic)]-ubi 29-41 designed for the labeling with 99mtc using tricine as coligand. methods: synthesis was preformed on a ...

introduction: neurotensin (nt) is a tridecapeptide that binds specifically to neurotensin receptors. several forms of cancer, including small cell lung cancer, colon, pancreatic and prostate carcinomas especially exocrine pancreatic carcinomas express receptors for neurotensin peptide. radiolabeled neurotensin derivatives with a high affinity for these receptors might be used for scintigraphy. ...
