An analysis of small molecules called “metabolites” in a blood sample may be used to determine whether a person is following a prescribed diet, scientists at Johns Hopkins Bloomberg School of Public Health have shown. Clinical trials of diets and their health impacts are often plagued by participants’ poor adherence to assigned diets, which can make it difficult or even […]

A gene signature in the bloodstream could reveal whether someone is going to develop active tuberculosis (TB) disease months before symptoms begin. Such a signature has now been developed by a team led by the Francis Crick Institute and University of Leicester, in collaboration with BIOASTER and bioMerieux in France and the University of Cape Town in South Africa. The […]

New, improved ways to fight hypertension and low blood pressure may be in the offing, thanks to a discovery of how blood pressure is controlled. National University of Singapore researchers have found a new means of controlling blood pressure that involves the protein galectin-1, present in blood vessels and various other tissues. The researchers showed that galectin-1 reduces the activity […]

Hematopoietic stem cells (HSCs) give rise to blood and immune cells, and are therefore essential for survival. The group of Manuela Baccarini at the Max F. Perutz Laboratories, a joint venture of the University of Vienna and the Medical University of Vienna, has now shown how intracellular signaling can safeguard this delicate balance between activation and dormancy. Their results are […]

A quick and robust blood test that can detect liver damage before symptoms appear has been designed and verified using clinical samples by a team from UCL and University of Massachusetts. The researchers say the test could address a huge need for early detection of liver disease as it distinguishes between samples taken from healthy individuals and those with varying […]

The blood of schizophrenia patients features genetic material from more types of microorganisms than that of people without the debilitating mental illness, research at Oregon State University has found. What’s not known is whether that’s a cause or effect of the severe, chronic condition that strikes about one person in 100. “It’s a common assumption that healthy blood is sterile […]
