adenoid cystic carcinomas are deceptive malignancies that show slow growth and local invasion with recurrences seen many years after diagnosis. upto 50% of these tumors occur in the intraoral minor salivary glands usually in the hard palate. buccal mucosal tumors are relatively rare. we determined the incidence of buccal mucosal adenoid cystic carcinoma by reviewing the number of reported cases...

background and objectives: this study was carried out with the objective of determining the genomic variability of p. aeruginosa strains isolated from patients suffering from cystic fibrosis or from environmental cultures collected from different locations in the unit they admitted. materials and methods: a total of 57 clinical and environmental p. aeruginosa isolates were genotyped by enteroba...

background: echinococcosis or hydatid disease is a zoonotic infection caused by larval (metacestode) stages of cestodes belonging to the genus echinococcus, family taeniidae . we aimed to subclone antigen b gene in pqe-30 plasmid, its expression, and purification. methods: we subcloned hi gene into pqe-30 expression vector. the recombinant vector was transformed into e. coli , m15 and mass cult...

background: the objective of this study was to determine the prevalence of cystic echinococcosis (ce) in qom province, central iran using elisa test. methods: overall, 1564 serum samples (800 males and 764 females) were collected from selected subjects by randomized cluster sampling in 2011-2012. sera were analyzed by elisa test using agb. before sampling, a questionnaire was filled out for eac...

uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...

Background: Some antigens of H. pylori are excreted into the stool of infected people. These antigens can be used to detect the infection by immunoassays such as ELISA. Our aim was to identify these antigens by immunoblotting and affinity chromatography techniques. Methods: Four different antigenic preparations, namely, whole cell sonicate (WCS), outer membrane proteins (OMPs), cytoplasmic anti...

introduction: intravenous drug users as a serious health problem in communities have economical and social effects as well as health and hygienic complications. viral infections may be transmitted through drug injection by shared syringes among users. the aim of this study has been to determine the relative frequency of hbv, hcv and hiv infection’s markers as epidemiological data in ahvaz. mate...

conclusions in hbeag positive chb patients, low serum hbsag level is a useful predictor of compensated cirrhosis. objectives the aim of our study was to evaluate serum hbsag level as a biomarker for compensated cirrhosis in hepatitis b e antigen (hbeag) positive chb patients. patients and methods two-hundred and one hbeag-positive chinese chb patients with or without cirrhosis were enrolled in ...

Background: Infections due to Pseudomonas aeruginosa are among the leading causes of morbidity and mortality in patients who suffer from impaired immune responses and chronic diseases such as cystic fibrosis. At present, aggressive antibiotic therapy is the only choice for management of P. aeruginosa infections, but emergence of highly resistant strains necessitated the development of novel alt...

Cystic echinococcosis (CE) is an infection caused by the larval stage of Echinococcus granulosus. This is widely distributed through Iran, where a variety of animals act as intermediate host. The immunogenic antigens (Ag) of different compartments of the hydatid cyst have been already determined. One of these compartments is the laminated layer (LL). We have extracted a protein with the MW of 2...
