The incidence of Papillary Thyroid Carcinoma (PTC) has increased gradually in recent years, especially for Papillary Thyroid Microcarcinoma (PTMC). The purpose of this study was to evaluate the expression of Ki67, CK19, Galectin-3 and HBME-1 protein in PTMC and evaluate the clinical significance of differential diagnosis. The specimens of 80 PTMC cases and 40 benign papillary hyperplasia thyroi...

Learning and memory requires energy-demanding cellular processes and can be enhanced when the brain is supplemented with metabolic substrates. In this study, we found that neuroglial cell metabolic activity was significantly elevated when cultured in the presence of polyhydroxybutyrate (PHB) degradation product 3-hydroxybutyrate (3-HB) and derivatives. We demonstrated that the receptor for 3-HB...

The distinction between benign and malignant thyroid tumors is critical for the management of patients with thyroid nodules. We applied immunohistochemical staining for galectin-3, HBME-1, cytokeratin 19 (CK19), high molecular weight cytokeratin (HMWCK), cyclin D1 and p27(kip1) in 295 thyroid lesions to determine their diagnostic accuracy. The expression of all markers was significantly associa...

We have demonstrated previously that the preferential adhesion of prostate cancer cells to human bone marrow endothelial (HBME) cells may contribute to their preferential metastasis to bone. Although a subject of debate, it has been postulated that the endothelial cells of the bone marrow are fenestrated. It is unknown therefore whether prostate cancer cells adhere preferentially to the extrace...

hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...

background: carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. in the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. in cases which have morphological overlap,immunohistochemistry is needed for differential diagnosis. the purpose of this study is to investigate the expressions of cd56,hbme?1, cytokeratin 1...

AIMS To investigate the usefulness of immunohistochemical expression and immunolocalization of a panel of thyroid malignancy markers including HBME-1, cytokeratin (CK) 19 and galectin-3. METHODS AND RESULTS We evaluated 170 thyroid lesions including 148 neoplastic lesions [84 papillary carcinomas (PC), 38 follicular carcinomas (FC), 18 follicular adenomas, one hyalinizing trabecular tumour, f...

AIM We aimed to evaluate four immunohistochemical markers (HBME-1, Galectin-3, Cytokeratin-19 and CD56) used alone or in panels in a series of papillary thyroid carcinoma (PTC) and thyroid tumors of uncertain malignant potential (TT-UMP) cases. MATERIALS AND METHODS We performed an immunohistochemical analysis on a tissue micro-array of 11 PTCs [six classic (CPTC), five follicular variant (FV...

AIMS To evaluate CK19, RET, galectin-3 and HBME-1 expression in papillary thyroid carcinoma (PTC) and to evaluate their diagnostic significance. METHODS 155 PTC specimens and 83 other diseased-thyroid specimens were collected. Immunohistochemistry for CK19, RET, galectin-3 and HBME-1 was performed. RESULTS The 155 PTC cases were classified into eight variants according to the WHO classifica...

In this study, 105 cases of thyroid lesions were evaluated to assess the role of HBME-1, cytokeratin-19 (CK-19), galectin-3 in distinguishing benign from malignant thyroid lesions. Thirty-seven papillary, 10 follicular, 6 medullary, 1 mixed medullary follicular cell carcinoma, 3 poorly differentiated carcinoma, 18 adenomatous nodular hyperplasia, 30 follicular adenoma cases were included in the...
