Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Leading experts to discuss about emergence and growing use of point-of-care testing

Point-of-care testing is transforming healthcare: this type of testing helps patients get diagnosed and treated faster, and also makes it easier for patients in remote areas to have access to medical testing.

Study reveals how breast cancer uses exosomes to metastasize to the brain

Metastasizing breast cancers typically seek out the bones, lung, and brain. Brain metastases are especially dangerous; many women survive for less than a year after diagnosis. How is the cancer able to get past the blood brain barrier? And can it be blocked?

Scientists identify a potentially novel avenue to treat non-small cell lung cancers

Researchers at the University of Kentucky Markey Cancer Center have made a breakthrough discovery that solves a mystery long forgotten by science and have identified a potentially novel avenue in pre-clinical models to treat non-small cell lung cancers.

Innovative method could improve understanding of many processes in the body at molecular level

Cells are the basic building blocks of life - and, as such, they have been the object of intense study since the invention of the optical microscope in the 17th century.

Melatonin promises to help reduce bone loss in space flight

New research suggests that the problem of bone loss caused by microgravity conditions in space flight may be successfully treated using the time-tested drug melatonin. Melatonin increases the level of calcitonin in bone, which suppresses the bone-destroying activity of osteoclastic cells and helps maintain bone density.

'MasSpec Pen' could help distinguish between cancerous and healthy tissue during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur.

Sea snail compound shows potential as new anti-cancer pharmaceutical

The remarkable ability of a small Australian sea snail to produce a colorful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical.

Early detection method for pinpointing molecular signatures of Lyme disease

When researchers examined the mitochondrial DNA of Ötzi, a man entombed in ice high in the Tyrolean Alps some 5,300 years ago, they made a startling discovery.

Smoking simulator captures synthetic cannabinoid combustion products

Researchers have developed a smoking simulator that enables the reliable detection of the combustion products formed when synthetic cannabinoids are smoked.

New insights into protein transport could help define strategies for treating eye disease

Many forms of vision loss stem from a common source: impaired communication between the eye and the brain. And at the root of all eye-to-brain communication are the hundreds of proteins generated by the retina's nerve cells.

Humic substances extracted from coal can help fight viruses

Scientists from Russia demonstrated a novel approach leveraging the combination of high-resolution mass spectrometry and chemoinformatics to identify biologically active molecular components of humic substances extracted from coal, and discovered substances with antiviral activity against the tick-borne encephalitis virus.

CSIRO scientists can now detect gluten in any food

Scientists from Australia’s national science agency, CSIRO, can now detect gluten in any food and show which grain it comes from, making it easier for food companies to correctly label their products.

New test reveals truth behind gluten-free labels

Many people have wondered whether the gluten-free labeling on their groceries was true. Now, scientists in Australia have come up with a way to identify the presence of specific glutens in rye that indicate the presence of this grain in foods labeled “gluten-free”. Gluten is already known to be present in wheat, barley and oats.
