Immunohistochemical Distribution And Gene Expression Of Transforming Growth Factor Alpha In Ovarian Tissue Of Rats Treated With Capsaicin In Puberty, Sevda Eli̇ş Yildiz, Mümtaz Nazli, Gökhan Nur

Turkish Journal of Medical Sciences

In this study, the effects of capsaicin on the immunohistochemical distribution and gene expression of transforming growth factor alpha (TGF-\alpha) in ovarian tissue of rats at the pubertal age were examined. Materials and methods: Rats (50 days old) were divided into experimental, alimentation, and sham groups. The experimental group was injected with 1 mg/kg doses of capsaicin (10% ethanol and 1% Tween in an 80% distilled water mixture) subcutaneously every day for a period of 1 week. The alimentation group received 1 mg/kg doses of capsaicin (10% ethanol and 1% Tween in an 80% distilled water mixture). The sham group …


Diagnostic Value Of Cytokeratin 19, Hbme-1, And Galectin-3 Immunostaining Of Cell Block From Fine-Needle Aspiration Specimens In Papillary Carcinoma Of The Thyroid, Hacer Haltaş, Reyhan Bayrak, Si̇bel Yeni̇dünya, Ümran Yildirim Jan 2013

Diagnostic Value Of Cytokeratin 19, Hbme-1, And Galectin-3 Immunostaining Of Cell Block From Fine-Needle Aspiration Specimens In Papillary Carcinoma Of The Thyroid, Hacer Haltaş, Reyhan Bayrak, Si̇bel Yeni̇dünya, Ümran Yildirim

To evaluate the utility of immunohistochemical staining of cytokeratin 19 (CK19), HBME-1, and galectin-3 in cell block preparations of fine-needle aspiration cytology specimens as ancillary techniques for the differential diagnosis of papillary thyroid carcinoma. Materials and methods: Immunohistochemical detection of CK19, HBME-1, and galectin-3 was completed in 45 thyroid aspiration cytology specimens fixed in paraffin-embedded blocks consisting of the following cytologic diagnoses: 1) 16 cases of papillary carcinoma, 2) 16 cases suspicious for papillary carcinoma, and 3) 13 cases involving nonneoplastic lesions. Results: The follicular cells in the cytologically unequivocal papillary carcinoma diagnosis group expressed diffusely positive (+++) CK19, HBME-1, …

The Expression Of Cell Adhesion Molecules In Colorectal Cancer Tissue And Its Clinical Values, Dong Chen, Huiying Zhao, Feng Ye

To investigate the role of cell adhesion molecules CD44v6 and CEA in the occurrence, development, and metastasis of colorectal cancer (CRC). Materials and methods: The expression of CD44v6 and CEA in 76 CRC tissues and 43 normal colon tissues was detected using an immunohistological technique. The relationship between the 2 molecules’ expression and their pathologic characteristics, especially for metastasis, was investigated. Furthermore, the relevance between the expression of CD44v6 and of CEA was also assessed. Results: Expression of CD44v6 and CEA protein in CRC tissues was higher than in paracarcinoma tissue and normal colorectal mucosa (both P < 0.001). Positive expression of CD44v6 in CRC was associated with lymph node metastasis, Dukes’ stage, and histological differentiation. Higher expression intensity of CEA in CRC was related to lymph node involvement, distant metastasis, and invasion depth. Combining analysis of CD44v6 and CEA can improve the sensitivity and specificity in evaluating the metastatic potential of CRC (P < 0.05). There was no relevance between the expression of CD44v6 and CEA in CRC (P > 0.05). Conclusion: CD44v6 …
