purpose: to present a patient with localized corneal edema due to a small retained fragment of nucleus in the anterior chamber after uncomplicated phacoemulsification. case report: a 74-year-old female subject with history of phacoemulsification in her right eye about 1.5 years ago complained of foreign body sensation, pain and decreased vision in the same eye. visual acuity of that eye had dec...

background: trichomoniasis is a worldwide protozoan parasitic disease and metronidazole is a choice drug for its treatment. because of disease importance in public health and its controversial ideas about the prevalence of drug resistance, this study was carried out. methods: fifty-two suspected vaginal samples were collected from 2006 to 2007 in gynecology maryam hospital, tehran, iran. all is...

conclusions using the pcr-rflp method, three distinctive h. pylori caga genotypes were detected in antral biopsies. genotype i, which was predominant among the isolates, was significantly associated with gastritis. however, the data showed that caga genotype iii may play a role in duodenitis and duodenal ulcers in patients infected with h. pylori. patients and methods a total of 161 gastric bio...

long-term complications of retained war fragments in the body are not completely known. also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. we reviewed the literature on complication of retained war fragments and report our...

conclusions the results revealed that the strains under study could be epidemically related. it seems that an alternative subtyping method is needed to study the relationship among clinical s. sonnei strains and their transmission. here, we reported for the first time, two strains of s. sonnei with a different pcr-rflp pattern for ipah gene. results all shigella isolates were positive for both ...

background and aims: a multiplex transcription-polymerase chain reaction (m-pcr) was developed for direct detection and discrimination between canarypox virus (cpv) and other avian poxvirus (apv). materials and methods: three compatible primer sets were designed for m-pcr amplification of different loci fpv126, fpv140, and fpv167 located at highly conserved apv genes. results: results showed th...

background: light chain (lc) and heavy chain carboxyterminal subdomain (hcc) fragments are the most important parts of tetanus neurotoxin (tent) which play key roles in toxicity and binding of tent, respectively. in the present study, these two fragments were cloned and expressed in a prokaryotic system and their identity was confirmed using anti-tent specific polyclonal and monoclonal antibodi...

results all 90 campylobacter isolates confirmed by m-pcr were successfully typed using flaa-pcr-rflp. eleven different types were defined according to flaa-typing method and the rflp patterns were located at three separate clusters in rflp image analysis dendrogram. conclusions campylobacter jejuni isolates significantly showed more variety than c. coli isolates. a relatively low genetic divers...

conclusions several previous studies used pcr-rflp to genotype hbv; however, we showed the high risk to obtain atypical profiles, especially in advanced stages of chronic infection, with as results difficulties to genotype the virus. these profiles resulted from the accumulation of mutations during natural course of infection resulting in a modification in restriction sites for enzymes. so, we ...
