Scientists find Urine Test could offer a non-invasive approach for diagnosis of IBS

Scientists at McMaster University have identified new biomarkers for Irritable Bowel Syndrome (IBS) in urine, which could lead to better treatments and reduce the need for costly and invasive colonoscopy procedures currently used for diagnosis.

Little is known about the causes of IBS, a chronic and often debilitating gastrointestinal disorder which affects hundreds of thousands of Canadians in which diagnosis is complicated, patients experience a vast spectrum of symptoms and treatment options are limited.

“Diagnostic testing for IBS involves a long process of excluding other related gut disorders, such as inflammatory bowel disease,” explains Philip Britz-McKibbin, lead author of the study and a professor in McMaster’s Depa...

Quorn Protein Builds Muscle Better than Milk Protein

Mycoprotein is unique to Quorn products

A study from the University of Exeter has found that mycoprotein, the protein-rich food source that is unique to Quorn products, stimulates post-exercise muscle building to a greater extent than milk protein.

The study evaluated the digestion of protein, which allows amino acids (the building blocks of protein) to increase in the bloodstream and then become available for muscle protein building in 20 healthy, trained young men at rest and following a bout of strenuous resistance exercise.

The young men performed the exercise and were then given either milk protein or mycoprotein. Their muscle building rates were then measured using stable isotope labelled “tracers” in the hours following protein consumption.

Animal proteins like milk are an exce...

Molecular Thumb Drives: Researchers store Digital Images in Metabolite Molecules

Experimental setup
The approach maps the ones the zeros of digital data to the presence or absence of particular molecules in solutions. The researchers used the scheme to encode image files in solutions.

In a step toward molecular storage systems that could hold vast amounts of data in tiny spaces, researchers have shown it’s possible to store image files in solutions of common biological small molecules.

DNA molecules are well known as carriers of huge amounts of biological information, and there is growing interest in using DNA in engineered data storage devices that can hold vastly more data than our current hard drives. But new research shows that DNA isn’t the only game in town when it comes to molecular data storage.

A study led by Brown University researchers shows that it’s possible to s...

HIV Eliminated from the Genomes of Living Animals

A working model for HIV-1 elimination. A cartoon illustration of the viral elimination strategy is shown for single LASER ART, AAV9-CRISPR-Cas9 injection groups and dual treatment groups. We highlight the observed restriction of viral infection by LASER ART and an inability to achieve elimination of virus by AAV9-CRISPR-Cas9 treatment alone. However, the sequential administration of LASER ART and AAV9-CRISPR-Cas9 can achieve viral elimination in a subset of animals. Why specific animals are cured of infection while others are not is incompletely understood but tied, in measure, to viral set points

Researchers have for the first time eliminated replication-competent HIV-1 DNA – the virus responsible for AIDS – from the genomes of living animals...
