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.
A group led by researchers affiliated with the Phycology Laboratory at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, have discovered a new species of green microalga in a reservoir located in the northwest of the state.
Only 21 percent of patients with severe pneumonia caused by SARS-CoV-2 (the virus that causes COVID-19) have a documented bacterial superinfection at the time of intubation, resulting in potential overuse of antibiotics, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
Reverse transcription-polymerase chain reaction (RT-PCR) has been the gold standard for diagnosis during the COVID-19 pandemic.
Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.
Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.
Many individuals would like to prevent sloughed-off skin and bodily fluids. However, for marine biologists like Cheryl Lewis Ames, Associate Professor of Applied Marine Biology in the Graduate School of Agricultural Science at Tohoku University (Japan), such life remnants have become a magical guide to detecting the unseen.
An innovative test that determines the quality and quantity of inactive HIV viruses in the genes of HIV patients may ultimately give scientists a better idea of effective drugs.
Although it is known that mutations in the SARS-CoV-2 genome occurred and spread, the effect of those mutations is not yet clear.
Meat and fish fraud are worldwide issues that cost consumers billions of dollars annually.
The COVID-19 pandemic has highlighted the need for rapid and accurate nucleic acid detection at the point of care.
Researchers from the University of Basel have developed a sensitive testing system that allows the rapid and reliable detection of resistance in bacteria.
A recent paper explored the possibility of using serologic testing as an adjunct diagnostic method in the diagnosis of SARS-CoV-2 infection.
A paper published on medRxiv describes a repurposed type III CRISPR-Cas system that can detect the virus from nasopharyngeal swabs in less than an hour.
Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute.
In May, a fishing vessel exited a port and returned with the first-ever proof that neutralizing antibodies offer protection from being re-infected by SARS-CoV-2.
Rare genetic mutations occurring in cells cannot be detected by existing sequencing techniques because these methods do not have the required sensitivity.
Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.
A rapid laboratory test, the eosinophil count, readily obtained from a routine complete blood cell count (CBC) can aid in the early recognition of COVID-19 in patients, as well as provide prognostic information, according to new research in The Journal of the American Osteopathic Association.
Both symptomatic and asymptomatic COVID-19 patients have the capability of contaminating their surroundings, according to a new study published in mSphere.
MicroRNAs, are attracting interest relating to human diseases because variations in the expression of miRNAs are often associated with abnormal functions.
