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.

Five key proteins form new, early-warning blood test before heart attack strikes

A team of Johns Hopkins biochemists has identified a mixed bag of five key proteins out of thousands secreted into blood draining from the heart's blood vessels that may together or in certain quantities form the basis of a far more accurate early warning test than currently in use of impending heart attack in people with severely reduced blood flow, or ischemia.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

NIH funds two new centers for imaging technology for neurodegenerative disorders and software for protein analysis

The National Center for Research Resources (NCRR), a part of the National Institutes of Health (NIH), announced today it will provide up to an estimated $11 million over the next five years to create two new Biomedical Technology Research Centers (BTRCs) that will provide researchers nationwide with access to specialized research tools, training and state-of-the-art equipment.

Existing anti-obesity drugs may be effective against flu, hepatitis and HIV

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, according to a study published today in the journal Nature Biotechnology.

New technology to analyse human cells

A new technology which enables scientists to identify proteins by making a map of the energy flow inside the protein is revealed in Proceedings of the National Academy of Sciences (PNAS) journal.

New technique in blood analysis may speed diagnosis of heart attacks

Someday doctors may be able to use a blood test to confirm within minutes, instead of hours, if a patient is having a heart attack, allowing more rapid treatment that could limit damage to heart muscle.

Skin odors used to detect basal cell carcinoma

According to new research from the Monell Center, odors from skin can be used to identify basal cell carcinoma, the most common form of skin cancer. The findings, presented at the 236th meeting of the American Chemical Society, may open doors to development of new methods to detect basal cell carcinoma and other forms of skin cancer.

Scientists discover reservoir of mitochondrial DNA mutations present in the general population

Researchers at the University of Newcastle, England, and the Virginia Bioinformatics Institute at Virginia Tech in the United States have revealed a large reservoir of mitochondrial DNA mutations present in the general population. Clinical analysis of blood samples from almost 3,000 infants born in north Cumbria, England, showed that at least 1 in 200 individuals in the general public harbor mitochondrial DNA mutations that may lead to disease.

How short RNAs influence many proteins

During the last decade, microRNAs have emerged somewhat surprisingly as key players in the way genes are regulated. These short snippets of RNA do their work by interacting with messenger RNAs, which act as blueprints for protein creation.

Enzyme may explain how hepatitis C infection causes fatty liver

A key enzyme may explain how hepatitis C infection causes fatty liver - a buildup of excess fat in the liver, which can lead to life-threatening diseases such as cirrhosis and liver cancer, report University of Pittsburgh Graduate School of Public Health and School of Medicine researchers.

Protein found in immune cells may be a reliable marker for schizophrenia risk

Schizophrenia is a severe and complex psychiatric illness that affects about 1% of the population. Diagnosis currently relies on subjective clinical interviews and the assessment of ambiguous symptoms, which frequently leads to delayed diagnosis and treatment. As such, biomarkers that would indicate schizophrenia risk or onset would be extremely useful.
