Comparison of Modified Papanicolaou and Hematoxylin and Eosin Stain in Demonstration of Keratin Pearl and Individual Cell Keratin in Oral Squamous Cell Carcinoma
Keratin is an intermediate filamentous protein generally found in the surface epithelium (Clausen et al., 1986; Steinert et al., 1995; Coulombe et al., 1990; Neville et al., 2002). Their role is to protect the underlying structures, which is one of the prime functions of surface epithelium (Tencate, 1998). The keratin synthesis reflects the differentiation level of normal epithelial cell as wel...
متن کاملDemonstration and Comparison of Keratin Pearl and Individual Cell Keratin in Oral Squamous Cell Carcinoma using Modified Mallory’s Stain and Hematoxylin and Eosin
Oral squamous cell carcinoma is one of the most common oral malignant tumors comprising of 90-95 % of cases (Pindborg et al., 1990; Harrison et al., 1999). It is commonest malignancy in Indian sub continent (Pindborg et al., 1990; Parija, 1991). It is histologically graded as well, moderate and poorly differentiated tumor based on several factor (Neville et al., 2002’ Neville et al., 2002). One...
متن کاملExpression of Hsp90α and cyclin B1 were related to prognosis of esophageal squamous cell carcinoma and keratin pearl formation.
Hsp90α (heat shock protein 90α), one of the important molecular chaperones in cancer cell signal transduction, has been a new candidate target for cancer therapy. Cyclin B1, the client protein of Hsp90α, plays a key role as a mitotic cyclin in the G2-M phase transition during the cell cycle progression. However, the relationship between the level of HSP90α and cyclin B1, the location of Hsp90α ...
متن کاملKeratin 13 is a more specific marker of conjunctival epithelium than keratin 19
Introduction To evaluate the expression patterns of cytokeratin (K) 12, 13, and 19 in normal epithelium of the human ocular surface to determine whether K13 could be used as a marker for conjunctival epithelium. Methods: Total RNA was isolated from the human conjunctiva and central cornea. Those transcripts that had threefolds or higher expression levels in the conjunctiva than the cornea wer...
متن کاملPearl drops
– If deposited on a hydrophobic rough substrate, a small drop of water can look like a pearl, with a contact angle close to 180. We examine the conditions for observing such a phenomenon and show practical achievements where the contact angle can be predicted and thus quantitatively tuned by the design of the surface microstructure. Presentation. – The contact angle of a drop on a solid is idea...
