introduction: non-ossifying fibroma (nof) is a relatively common benign and non-neoplastic lesion in long bones of children and adolescents. as far as very few cases of nof have been reported in jaws and what was managed to be found regarding all reported cases having occurred only in the mandible, in this article we are going to report a case of maxillary nof in a 38-year-old female.

background: the piwi-interacting rna (pirna) pathway has an essential role in transposon silencing, meiosis progression, spermatogenesis, and germline maintenance. hiwi genes are critical for pirna biogenesis and function. therefore, polymorphisms in hiwi genes contribute to spermatogenesis defects and can be considered as risk factors for male infertility. the aim of the present study was to i...

an r-module m is called strongly noncosingular if it has no nonzero rad-small (cosingular) homomorphic image in the sense of harada. it is proven that (1) an r-module m is strongly noncosingular if and only if m is coatomic and noncosingular; (2) a right perfect ring r is artinian hereditary serial if and only if the class of injective modules coincides with the class of (strongly) noncosingula...

corrosion of reinforcing steel and other embedded metals is the main cause of severe deterioration in reinforced concrete structures which subsequently imposes adverse effects on ultimate and serviceability limit state performance of the whole structure. in this paper, a new corrosion detection method for reinforced concrete beams, based on wavelet analysis is presented. to evaluate the capabil...

pure rockfill dams have been found specific attention in watershed management and flood control, recently. in addition to hydraulic specific features, one of the important advantages of these structures is their consistency with nature and environment. normally, floods are accompanied with high sediment loads which may enter the body of dam. when flow through dam body governed by hydraulic grad...

poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (pead/sio2) containing 3 wt. % sio2  were prepared by an in situ method. the examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (dsc). the avrami, ozawa, and combined avrami and ozawa equations were applied to describe the crystallization kinet...

carcinogenesis is a multistep process characterized by the gradual accumulation of genetic changes that ultimately lead to cancer. these genetic mutations can impart limitless replicative potential to the cancer cells making them immortal. telomeres are repeat nucleotide sequence ttaggg that are present at the end of chromosomes. its functions are to protect the chromosomal ends and to ensure t...

abstract background involvement of lacrimal apparatus by non hodgkin lymphoma as a first manifestation is extremely rare and only three cases have been reported in children. the purpose of this report is to determine the clinical characteristic of patient with primary involvement of lacrimal apparatus with lymphoma. case presentation a 7-year-old girl with history of tearing, gradually progress...

this paper investigates different kinds of control predicates in persian subjunctive complements. first, it is shown that the obligatory control (oc) constructions syntactically consist of two subtypes exhaustive control (ec) and non-exhaustive control (nec). then building upon jackendoff and culicover (2003) and culicover and jackendoff’s (2005) semantic analysis of control which is devoted to...
