results of 50 patients, 20 were men and 30 women with mean age of 61.1 ± 16.9 years ranged between 22 and 85 years. all samples of pterygia had positive results for adenoviruses dna with polymerase chain reaction, but none of the negative control groups displayed adenoviruses. the pterygium group and the control groups were β-globin positive. direct sequencing of pcr products confirmed adenovir...
background aggregatibacter actinomycetemcomitans and tannerella forsythensis are two major pathogens in destructive periodontal disease in humans. the detection of these bacteria is needed for diagnosis and management of the mentioned diseases. objectives we aimed to develop and compare improved multiplex conventional and sybr green real time pcr assays for a specific diagnosis of the organisms...
conclusions: vegetables are a new source of h. pylori and accurate washing of vegetables improves such contaminations. results: the results showed that 44 of 460 samples (9.56%) were positive for h. pylori using the culture method. the polymerase chain reaction technique showed that 50 of 460 samples (10.86%) were positive for h. pylori. un-washed leek, traditional salad, un-washed basil and un...
abstract background brucellosis is endemic in iran, and is seen in all age groups, including children. its diagnosis in childhood needs a high index of suspicion. the diagnostic methods currently in use need evaluation for analytical performance. objective the present study tries to evaluate the hematological indices, serologic markers of inflammation and symptoms in patients suspected of bruce...
Bovine brucellosis is a zoonotic disease distributed worldwide and characterized by abortion and reducedfertility in cows. Since brucellosis eradication programme in Iran uses vaccination, test, slaughter andquarantine as control measures, it is essential to distinguish vaccine strains from strains that cause infectionsamong vaccinated cattle herds. We developed and evaluated a multiplex polyme...
Genomic DNA of a patient diagnosed with nonobstructive azoospermia and with the history of allogenic bone marrow transplantation from his sister due to chronic myeloid leukemia was isolated from peripheral blood in order to screen Y chromosome microdeletions. 13 short tagged sites belonging to AZF a, b, and c loci were detected with multiplex polymerase chain reaction technique. Bands were dete...
background: colorectal tumor is one of the main causes of death in our country. the aim of the present study was to determine the clinicopathological aspects of tumor and the presence of hepatic micrometastasis in patients with colorectal cancer (crc). materials and methods: forty two patients with crc were evaluated in the study surgical treatment was performed and liver biopsy was taken for t...
b ackground : one of the main mechanisms of resistance to carbapenems is potential of klebsiella pneumoniae to produce k . pneumoniae carbapenemase (kpc). kpc is an important type of carbapenemase, which can hydrolyze carbapenems and other beta-lactam antibiotics. modified hodge test (mht) and use of boronic acid as a kpc inhibitor are two types of phenotypic methods, which are use...
