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...

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...

PurposeCurrent polymerase chain reaction (PCR) methods for the diagnosis of infections are time consuming and require large sample volume skilled technicians. We developed a novel, easy-to-use, rapid (processing time, 1 minute; total 33 minutes) multiplex real-time PCR test (Direct Strip PCR) that did not DNA extraction to detect 9 pathogens could cause uveitis in 20-μl samples.DesignMulticente...
