Because the esophageal epithelium lacks a defined stem cell niche, it is unclear whether all basal epithelial cells in the adult esophagus are functionally equivalent. In this study, we showed that basal cells in the mouse esophagus contained a heterogeneous population of epithelial cells, similar to other rapidly cycling tissues such as the intestine or skin. Using a combination of cell-surfac...

basal cell carcinoma (bcc) is currently the most common cutaneous cancer found in humans. although it generally shows a relatively benign course (bccl), some cases show aggressive behavior (bcc2). until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between bcc 1 and bcc2. in this study we selected 50 cases of bcc and categorized them into two gro...

BACKGROUND Infundibulocystic basal cell carcinoma is a recently described distinctive clinicopathologic variant of basal cell carcinoma. Histopathologic differential diagnosis among infundibulocystic basal cell carcinoma, trichoepithelioma, and basaloid follicular hamartoma has generated controversy in the literature. OBSERVATIONS Members of 2 families with multiple infundibulocystic basal ce...

Epithelial cells within the normal breast duct seem to be the primary target for neoplastic transformation events that eventually produce breast cancer. Normal epithelial cells are easily isolated and propagated using standard techniques. However, these techniques almost invariably result in populations of cells that are largely basal in character. Because only approximately 20% of human breast...

Background: In addition to the well-defined histological criteria for squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), immunohistochemical techniques can be used in difficult cases for their differentiation. As differential diagnosis between trichoepithelioma (TE) and BCC is sometimes difficult for the clinician and the pathologist, CD10 may be a useful marker for definite diagnosi...

Background: Radiation-induced basal cell carcinoma (BCC) can be multiple, large, and recurring, which complicates its treatment in some cases. According to reports on the role of cyclooxygenase 2 (COX2) inhibitors in the treatment or prevention of non-melanoma skin cancers and considering the fact that COX2 expression has not been evaluated in radiation-in...

To study the anticoccidial and antioxidant effects of garlic powder (GP) and total sulfur amino acid (TSAA) on growth performance, faecal oocyst output, oxidative stress indicators and antioxidant status markers in broiler chickens, a 2 × 2 × 2 splitplot-factorial arrangement of treatments was used. A total of 480-day-old male broiler chickens were equally assigned to two plots. Two hundred for...
