Background Pilonidal sinus (PS) is considered to belong in the category of follicular occlusion diseases (acne triad). Objectives The aim of our study was to elucidate the pathogenesis of PS by evaluating its cytokeratin (CK) expression. Methods CK expression in nine cases of PS was studied immunohistochemically using six antikeratin antibodies. Results Infundibular-like epithelium contained CK...

BACKGROUND External irradiation (IRR) of advanced head and neck tumors often includes tissues of the larynx and trachea unaffected by cancer. In these normal tissues, both single-cell damage (necrosis, apoptosis, functional cell death) and interstitial damage (edema, fibrosis, vascular alterations, cellular infiltrations) resulting in tissue remodeling can occur, depending on various IRR parame...

Keratocystic odontogenic tumor (KCOT) is a benign intraosseous neoplasm of the jaw occurring most commonly in mandibular ramus molar area with male predilection. Peripheral KCOTs are very uncommon. Here we report a case of keratocyst in buccal mucosa in a 55 years old female patient, the diagnosis of which was based on subjective histological evaluation and further confirmed by immunohistochemi...

Definitions of basal-like breast cancer phenotype vary, and microarray-based expression profiling analysis remains the gold standard for the identification of these tumors. Immunohistochemical identification of basal-like carcinomas is hindered with a fact, that on microarray level not all of them express basal-type cytokeratin 5/6, 14 and 17. We compared expression of cytokeratin 5, 14 and 17 ...

A few linkage maps of tea have been constructed using pseudo-testcross theory based on dominant marker systems. However, dominant markers are not suitable as landmark markers across a wide range of materials. Therefore, we developed co-dominant SSR markers from genomic DNA and ESTs and constructed a reference map using these co-dominant markers as landmarks. A population of 54 F(1) clones deriv...
