Maxillary bone epithelial cyst is rare in dogs. A 5-year-old, spayed female miniature schnauzer developed a swelling below the nasal canthus of left eye. Plain radiograph demonstrated a 1.5 cm diameter of radiolucent lesion on the maxillary bone anteroventral to the eye, and contrast dacryocystorhinography confirmed an obstructed nasolarcrimal duct. The swelling showed poor response to antibiot...

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...

Glomerular development of the kidney was studied in newborn rats by electron microscopy. Four different stages of glomerular development were defined: vesicle fonnation, S-shaped body stage, capillary loop fonnation, and glomerular maturation. In the fust stage, the mesenchymal cells form a spheroid mass. This is followed by the S-shaped body stage in which clefts appear in the mass. Afte...

introduction: the aim of this study was to investigate the growth and development of mouse two cell embryo on human uterine polarized monolayers. material and methodes: human endometrial tissue was obtained from patients who had undergone total hysterectomy. then, epithelial cells were isolated by collagenase i 0.25% and cultured on either ecm gel coated millipore filter insert (polarized) or p...

Pindborg tumor is a rare benign epithelial odontogenic tumor occurring most frequently in the posterior part of the lower jaw. I herein report a case of a 12 year old pediatric male patient with a painless swelling of the left maxilla of 5 months duration. Radio graphically, a well circumscribed unilocular radiolucency containing radiopaque foci associated with impacted tooth was seen, along wi...

Objective(s): Growing evidences have indicated microRNAs as modulators of tumor development and aggression. On the other hand, a phenomenon known as epithelial-mesenchymal transition (EMT) that indicates a transient phase from epithelial-like features to mesenchymal phenotype is a key player in tumor progression.  In this study, we aimed to assess the potential impacts...

A fibroadenoma was diagnosed in the mammary gland of a lamb by immunohistochemical method andmeasurement of oestradiol hormone. The tumor was characterized by an encapsulated firm mass with acreamy-white cut surface. Histologically, it consisted of variably-sized sinus ducts, covered by a single ormultiple layers of proliferated epithelial cells, and embedded in a loose connective tissue. Immun...

expansible soils are those which will suffer considerable swelling and volume change when subjected to water. the resulting swelling pressure may cause complete destruction of such light structures as irrigation canal linings, floor slabs, etc. based upon previous investigations, swelling of clayey soils has been blamed for failure of many irrigation canals in iran and in other countries of the...

ameloblastomas are slow growing, locally invasive, benign odontogenic tumors of an epithelial origin, accounting for approximately 1% of all oral tumors. a 40-year-old man presented with a chief complaint of a swelling over the left side of his face of 4 years’ duration. on examination, gross facial asymmetry was detected, and a well-defined swelling was noted intraorally involving the left max...
