1. Papillary osmolality and sodium and potassium concentrations were determined in rats during a control period and during escape from the sodium-retaining effect of deoxycorticosterone acetate and compared with the changes observed after acute frusemide injection. 2. During escape, papillary osmolality [554 +/- 36 vs 754 +/- 42 mmol/kg of papillary water (H2O), P less than 0.005] and papillary...

Familial adenomatous polyposis (FAP) is caused by germ-line mutations of the apc gene, and it is associated with an increased risk of developing papillary thyroid carcinomas. We have previously reported that a significant fraction of sporadic human papillary thyroid carcinomas is characterized by gene rearrangements affecting the ret protooncogene. These rearrangements generate chimeric transfo...

Due to exponential growth and high diversity of DICOM images in healthcare industry, medical image mining has gained prominent attention because extraction of useful and effective patterns is one of the major problems in DICOM images. For instance, differentiating between the mimic, mix and complex patterns of thyroid papillary carcinoma (PTC) and other cancers in FNAC images is really challeng...

Background: Thyroid carcinoma is the most common malignancy of the endocrine system. Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer, accounting for 70–90% of well-differentiated thyroid malignancies. Thyroid papillary microcarcinoma is a subtype of papillary carcinoma that included tumors with less than 10mm diameter. As a result of diagnostic methods improvement, p...

Introduction: Synovial sarcoma makes up 8–10% of all soft tissue sarcomas, and constitutes 3–10% of all sarcomas occurring in the head and neck region. It shows male predominance (3:2), and the mean age of presentation is 30 years.   Case Report: A 51-year-old gentleman presented with right-sided neck swelling which had been progressively increasing in size for the past 2 years. A computed ...

Papillary thyroid cancer is the most prevalent histologic type of carcinoma. There are numerous PTC subtypes that have been identified, with classical being prevalent. The follicular variant (FVPTC) second subtype papillary A case encapsulated carcinoma was studied which showed a well tumour cells arranged predominantly in architecture and few areas showing solid architecture. no capsular invas...

In this study, we compare the morphological and genetic characteristics of 38 post-Chernobyl thyroid papillary carcinomas from Belarussian children 5-18 years old with those of 23 sporadic papillary carcinomas from the same age children without history of radiation exposure from Los Angeles and Cincinnati. Among radiation-induced tumors, solid variant of papillary carcinoma was found in 37%, fo...

OBJECTIVE We wanted to evaluate the degree of conformity of papillary carcinoma and follicular carcinoma to the reported ultrasonographic findings of malignant thyroid tumor. MATERIALS AND METHODS Between January 2003 and December 2004, fine needle aspiration biopsy was performed in 1,036 patients with palpable and nonpalpable thyroid lesions. We retrospectively reviewed the ultrasonographic ...
