Tumours of odontogenic origin have been reported in various domestic animals. Ameloblastic fibroodontomais a rare tumour derived from odontogenic epithelium and pulpal mesenchyme. Plain andformalised sections from masses on the front of the cranial aspect of the jaw and the end of the tongue of acastrated beef cattle from an abattoir was submitted to Mt Pleasant laboratories, Launceston, Austra...

nutritive value of rumen epithelial scraping (rep) was assessed using in sacco and in vivo procedures. concentrates were so formulated that 0% (a), 35% (b), 70% (c), and 100% (d) of soybean meal (sbm), were replaced (weight for weight) with rep. in a completely randomized design, 16 west african dwarf (wad) goats were randomly allocated to the experimental diets to assess feed intake and digest...

calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

background: an increase in the number of intraepithelial lymphocytes (iel) in the duodenal mucosa is an important criterion for the histological diagnosis of celiac disease (cd). we determined the normal range for intraepithelial lymphocytes (iel) in the second part of duodenum in healthy iranian population. materials and methods: four biopsy samples of the endoscopically normal appearing mucos...

background: vitamin d plays a critical role in the regulation of growth and differentiation of squamous epithelium. the pleiotropic effects of 1,25-dihydroxyvitamin d3 [1,25(oh)2d3], include proliferative, pro-apoptotic, and pro-differentiation effects on numerous cell types. although 1,25-dihydroxyvitamin d3 is involved in the regulation and differentiation of epithelium, there is no data in t...

objective: tooth loss is a common problem and since current tooth replacement methods cannot counter balance with biological tooth structures, regenerating natural tooth structures has become an ideal goal. a challenging problem in tooth regeneration is to find a proper clinically feasible cell to seed.this study was designed to investigate the odontogenic potential of human bone marrow mesench...

Background: Methylphenidate (MPH), Ritalin, is one of the most common medications. The administration of Ritalin leads to increase of the activity of central nervous system. Ritalin may be used for maintaining alertness and improving of attention which may lead to increase of the risk of substance abuse in some cases. There is a little data about the effects of long term treatment with Methylph...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...
