aim : the purpose of this study was to investigate the prevalence of enteropathogenic escherichia coli (epec) and shiga toxin producing e. coli (stec) strains in healthy broilers in iran.   background : stec and epec strains as diarrheagenic e. coli are among the most prevalent causative agents in acute diarrhea. domestic animals, mainly cattle and sheep, have been implicated as the principal r...

background: phlebotomus perniciosus and phlebotomus longicuspis are two phlebotomine sand fly species morphologically similar and differing in males only by the shape of the copulatory valves which are bifurcated in p. perniciosus , tip long and tapered in p. longicuspis . methods: a count of the median coxite setae was carried out on 208 specimens from the collections of dedet and of parrot, i...

conclusions: the results obtained from this study support the idea that the timi and modified timi risk scores might be valuable tools that could be used to stratify the risk of patients with atypical chest pain in the emergency department. results: no significant difference could be observed between both groups regarding demographic characteristics, ejection fraction, left ventricle hypertroph...

Introduction : The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. Materials and methods: All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT) were evaluated before surgery for lung cysts or unknown lesions. R...

background: endometrial cancer is the most common gynecologic malignancy that has often proceeded by a premalignant phase. modern molecular and immune staining methods for precancerous lesions diagnosis have been expanded. one of the genetic alternations in the endometrial cancer carcinogenesis is the mutational activation of the k-ras oncogene. k-ras mutation has recognized to occur at an earl...

Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas.  These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis.  Biopsies have been the gold standard for the diagnosis of such lesions.  This study reports on an acute presentation of giant peripheral ossifying fibrom...

To overcome the space limit of orifice-type and capillary restrictors in hybrid bearings, a kind of atypical long orifice-type restrictor is proposed and its experimental model is established. Through the analysis of the structure and flow rate of orifice-type restrictor and capillary restrictor, a long orifice-type restrictor and a feasible experimental modeling method are presented by use of ...

subcutaneous panniculitis-like t-cell lymphoma (sptcl) is an infrequent cytotoxic t-cell lymphoma of the skin with a unique immunophenotypic profile. here we describe this lymphoma in a 30-year-old iranian woman. she presented with periorbital edema, mandibular swelling with edematous areas on her face and two small lymph nodes (6-7mm) in the cervical area. histopathological findings revealed l...
