Adenomatoid odontogenic tumor (AOT) is a relatively rare, benign, hamartomatous, and cystic odontogenic neoplasm that was first described more than a century ago. The lesion still continues to intrigue experts with its varied histomorphology and controversies regarding its development. The present article describes a case of cystic AOT with an unusual histomorphology associated with an impacted...

the purpose of this study was to gain more information on the structure of different layers of renal arteryand comparing these structures in post-natal male and female sheep. to do so, right and left renal arteries of6 adult and 6 newborn animals were dissected; the middle parts of arteries were only collected. after tissueprocessing using paraffin embedding method, 5–6-μm sections were cut and...

morphological and histochemical study of the abomasal epithelium in camel (camelus dromedarius) wascarried out by light and scanning electron microscopes. the lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...

Small ruminants pancreas is a major accessory organ and has an important role in digestion. Endocrine part of pancreas is Islets of Langerhans which are highly vascularized, consisting of several endocrine cell types that function together to maintain glucose homeostasis. There has been limited scientific work done on the histomorphological study of pancreas in Deccani sheep Bidri goat. The pre...

in this investigation, diabetes was induced in adult male sprague-dawley rats by single intraperitoneal injection of streptozotocin (stz) at 45 mg kg-1 of body weight. a group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. the results revealed that, in the untreated diabetic rats, the body and testicular weigh...

introduction: the use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. in this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   materials and methods: for this work, 40 pregnant balb/c mice were randomly allocated to one c...

for this study the jejuni of 50 adult (2-4 years), apparently healthy iranian river buffaloes were collectedfrom the abattoir for gross morphology, histomorphology, and histomorphometry. our statistical analysisrevealed that, there are significant (p

Although histomorphology has made significant advances into the understanding of cancer etiology, classification and pathogenesis, it is sometimes complicated by morphologic ambiguities, and other shortcomings that necessitate the development of ancillary tests to complement its diagnostic value. A new approach to cancer patient management consists of targeting specific molecules or gene mutati...

Basal cell carcinoma (BCC) of the skin exhibits a very heterogeneous histomorphology, on the basis of which it is classified into several subtypes and variants. In many cases, however, a definite categorization remains difficult, because BCC may consist of more than one histopathological subtype. There are limited data exploring the characteristics of these mixed BCCs, since they have not been ...

It has been reported that hyperhomocysteinemia (HHcy) is associated with neurodegenerative and cardiovascular diseases. However, little is known about brain histomorphology, neuronal organelles, and hairy enhancer of split ( hes) expression under HHcy. In this study, non-HHcy and HHcy induced by high-methionine diet in apolipoprotein E-deficient (Apo E-/-) mice were comparatively investigated. ...
