background: retinoblastoma is the most common intraocular tumor in childhood and mutation in the rb1 gene will trigger the tumorigenesis. so far, a wide range of the mutations along the length of rb1 gene have been reported. however, some could not be detected by common detection methods. in such condition, linkage analysis using microsatellite markers is suggested to trace unknown rb1 mutation...

conclusions it is concluded that cryptosporidium spp. should be considered in immunocompromised diarrheal patients and elisa must be chosen for detection of this parasite. modified acid fast staining and cassette kit techniques could be performed if elisa is not available. the single use of the cassette kit will be inadequate for the diagnosis of cryptosporidiosis. background cryptosporidiosis ...

zinc is the first modelling language which supports solver and technique independence. this means that a high level conceptual model can be automatically mapped into an appropriate low level design model for a specific solver or technique. to date, zinc uses three different techniques to solve a model: constraint programming (cp), local search (ls), and mixed integer programming (mip). in this ...

background: sarcocystosis is one of the most widespread parasitic diseases in cattle caused by three main species of sarcocystis genus. the major aim of this study was to determine the prevalence of sarcocystis spp. in meat produced in yazd, central iran with special reference to species identification, using polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp).  method...

background primary small round blue cell tumors (srbct) in sinonasal comprise histogenetically diverse entities with overlapping morphologic features. because of the limited initial biopsy tissue materials, differential diagnostic difficulties may arise, and as they have different management, exact diagnosis and classification are very important. conclusions the results of our study indicate th...
