Polymerase Chain Reaction News and Research

RSS

Polymerase chain reaction (PCR) is a revolutionary laboratory technique that enables the replication of a specific DNA sequence. Using PCR, millions of copies of a target DNA can be easily synthesized within a short period of time.

Telomere length testing can alter treatment decisions for certain diseases

Research led by Johns Hopkins physicians and scientists shows that a test for measuring the length of DNA endcaps, called telomeres, which has a variability rate of 5 percent, can alter treatment decisions for patients with certain types of bone marrow failure.

Cannabis Quality and Contamination Testing

Dr. Bob Clifford has published and presented over 125 papers in the fields of food, pharmaceutical, environmental, energy, geology, material science, photonics, and cannabis. However, his true love is in food. After graduating with his Ph.D., he left his job with the FDA for Shimadzu where he has worked for the last 26 years.

New technique may reveal clues about role of centromeres in Down syndrome, other birth defects

Some scientists call it the "final frontier" of our DNA -- even though it lies at the center of every X-shaped chromosome in nearly every one of our cells.

TSRI scientists demonstrate repurposing of DNA to create new substances

DNA evolved to store genetic information, but in principle this special, chain-like molecule can also be adapted to make new materials. Chemists at The Scripps Research Institute have now published an important demonstration of this repurposing of DNA to create new substances with possible medical applications.

MRI and ultrasound can detect fetal brain damage caused by Zika in utero

Clinicians managing Zika-affected pregnancies should use magnetic resonance imaging (MRI) in addition to standard ultrasound (US) because the more detailed MRI images can reveal more extensive areas of damage to the developing fetal brain, according to research presented during IDWeek 2017.

New paper-based test can diagnose Zika infection within 20 minutes

MIT researchers have developed a paper-based test that can diagnose Zika infection within 20 minutes. Unlike existing tests, the new diagnostic does not cross-react with Dengue virus, a close relative of the Zika virus that can produce false positives on many Zika tests.

PolyU researchers uncover new hyper-resistant, hypervirulent superbug

The Partner State Key Laboratory of Chirosciences at the Department of Applied Biology and Chemical Technology of The Hong Kong Polytechnic University discovered a newly emerged superbug, hyper-resistant and hypervirulent Klebsiella pneumoniae, which may cause untreatable and fatal infections in relatively healthy individuals and will pose enormous threat to human health.

FDA issues Emergency Use Authorization for multiplex Zika test

The Center for Infection and Immunity at Columbia University's Mailman School today announced that the U.S. Food and Drug Administration has issued an Emergency Use Authorization for the CII-ArboViroPlex rRT-PCR Test, the first multiplex assay that simultaneously tests for the presence of Zika virus, all serotypes of dengue virus, chikungunya virus, and West Nile virus, as well as a host gene that ensures the accuracy of results.

Early life exposure to antibacterials could cause irreversible outcomes

Lawrence Livermore National Laboratory scientists have discovered that exposure to environmental levels of triclocarban (TCC), an antibacterial chemical common in personal care products like soaps and lotions as well as in the medical field, can transfer from mother to offspring and interfere with lipid metabolism.

Researchers identify new methods that could improve treatment for infectious diseases

Researchers have discovered new methods that could improve treatment for infectious diseases by enabling earlier detection of influenza outbreaks and curtailing inappropriate antibiotic usage. The findings were presented today at the 69th AACC Annual Scientific Meeting & Clinical Lab Expo in San Diego.

Diagnosing prostate cancer through a £225 urine test

This test, which we have branded SelectMDx for Prostate Cancer, came with the acquisition of a company in the Netherlands called NovioGendix. They developed a prototype assay, so they did most of the heavy lifting in terms of discovering the two specific biomarkers that are currently in the product. These biomarkers are tuned towards the detection of what I call clinically significant prostate cancer.
