Researchers at the 海角直播 have developed a novel technique that may give doctors a faster and more sensitive tool to detect pathogens associated with inflammatory bowel disease, including Crohn/news/wp-json/wp/v2/posts/35012/u2019s disease./news/wp-json/wp/v2/posts/35012/n
The new nanoparticle-based technique also may be used for detection of other microbes that have challenged scientists for centuries because they hide deep in human tissue and are able to reprogram cells to successfully evade the immune system./news/wp-json/wp/v2/posts/35012/n
The microbes reappear years later and can cause serious health problems such as seen in tuberculosis cases. Current testing methods to find these hidden microbes exist, but require a long time to complete and often delay effective treatment for weeks or even months./news/wp-json/wp/v2/posts/35012/n
UCF Associate Professor J. Manuel Perez and Professor Saleh Naser and their research team have developed a method using nanoparticles coated with DNA markers specific to the elusive pathogens. The technique is effective and more accurate than current methods at picking up even small amounts of a pathogen. More important, it takes hours instead of weeks or months to deliver results, potentially giving doctors a quicker tool to help patients./news/wp-json/wp/v2/posts/35012/n
/news/wp-json/wp/v2/posts/35012/u201cOur new technique has surpassed traditional molecular and microbiological methods,/news/wp-json/wp/v2/posts/35012/u201d said Naser, a professor at the UCF College of Medicine. /news/wp-json/wp/v2/posts/35012/u201cWithout compromising specificity or sensitivity, the nano-method produced reliable and accurate results within hours compared to months./news/wp-json/wp/v2/posts/35012/u201d/news/wp-json/wp/v2/posts/35012/n
The group/news/wp-json/wp/v2/posts/35012/u2019s translational research works is published in today/news/wp-json/wp/v2/posts/35012/u2019s edition of the journal PLoS ONE. To view the article click here./news/wp-json/wp/v2/posts/35012/n The team created hybridizing magnetic relaxation nanosensors (hMRS) that can fish out and detect minuscule amounts of DNA from pathogens hiding within a patient’s cells. The hair-thin hMRS are composed of a polymer-coated iron oxide nanoparticle and are chemically modified to specifically bind to a DNA marker that is unique to a particular pathogen./news/wp-json/wp/v2/posts/35012/n When the hMRS bind to the pathogen’s DNA, a magnetic resonance signal is detected, which is amplified by the water molecules that surround the nanoparticle. Then the researcher can read the change in the magnetic signature on a computer screen or portable electronic device, such as a smartphone, and determine whether the sample is infected with a particular pathogen./news/wp-json/wp/v2/posts/35012/n The researchers used Mycobacterium avium spp. paratuberculosis (MAP), a pathogen that has been implicated in the cause of Johne/news/wp-json/wp/v2/posts/35012/u2019s disease in cattle and Crohn/news/wp-json/wp/v2/posts/35012/u2019s disease in humans, to test out their technique.
