Gap junctions play a role in intercellular communication the epithelium, muscle and nerve tissues, many more tissues organs. These linking regions proteins forming them are called connexins (Cx). Recent studies show that cellular homeostatic equilibrium can be influenced by connexins. In this study, expression of Cx43 Cx32 basal cell carcinoma (BCC) squamous carcinomas (SCC) is tried studied. A...

Gottlieb, Helmut B., Lisa L. Ji, Heath Jones, Maurice L. Penny, Tiffany Fleming, and J. Thomas Cunningham. Differential effects of water and saline intake on water deprivation-induced c-Fos staining in the rat. Am J Physiol Regul Integr Comp Physiol 290: R1251–R1261, 2006. First published November 23, 2005; doi:10.1152/ajpregu.00727.2005.—We studied c-Fos staining in adult male rats after 48 h ...

the objective of the investigation was to improve the differential diagnosis of inflammatory bowel diseases, on the basis of an integrated assessment of morphological data, the findings of optical imaging of tissues, and immunohistochemical examinations of the oral mucosa. Materials and Methods. We studied morphological and immunohistochemical characteristics of the oral mucosae in each of 26 p...

OBJECTIVE The differential diagnosis of kidney tumors, especially those with eosinophilic cytoplasms, can be problematic due to overlapping morphologic features. CD138 is primarily a plasma cell marker but is known to be expressed in the proximal renal tubular epithelium as well. This study aims to investigate the possible contribution of CD138 expression in the differential diagnosis of kidney...

background and objective: tuberculosis is still a major health problem, involving about 1/3 of the world´s population. diagnosis is difficult when we only use ziehl-neelson staining. many cases may be missed. a more rapid and sensitive diagnostic method is necessary. pcr may be helpful. the aim of this study was to compare pcr, zieh-neelsen staining and histopathologic findings in diagnosis of ...

it is sometimes difficult to recognize a jaw lesion as osteosarcoma, ossifying fibroma or ‎fibrous dysplasia in routine hematoxylin and ‎eosin staining and a more accurate technique is needed to differentiate these ‎lesions. ‎many studies have shown the potential usefulness of silver-stained nucleolar organizer region (agnor) parameters for the diagnosis of various neoplasms. this study was car...

Objective(s) The main objective of this study was to investigate the status of chromosome stability in 3 human-mouse hybridoma cell lines over a period of time in various passages. Materials and Methods Metaphase spreads from 3 human-mouse cell lines (HF2X653, SPMO-4 and F3B6) that had been cultured in 4 successive passages, from 1 to 4 weeks, were prepared and analyzed. Metaphase chromosome...

Objectives The aim of this study is finding a practical and easy way to differentiate, between two malignant tumors Adenoid Cystic Carcinoma (ACC) and Polymorphous Low-grade Adeno Carcinoma (PLGA) histologically. In this regard, We proposed silver nitrate staining (AgNOR). Methods In this cross-sectional study, 30 parrafin-embedded blocks of ACC and 9 paraffin-embedded b...

Sinonasal myxoma/fibromyxoma is a rare benign neoplasm of uncertain histogenesis which can be locally aggressive. Surgical resection the preferred management. We present case sinonasal fibromyxoma in 30-year-old male who presented with frontal sinus tumour. Histopathological examination showed hypocellular spindle to stellate cell myxoid collagenous background, without nuclear atypia, mitoses o...
