Scientists have revealed that protein molecules in the brain are broken down and replaced at different rates, depending on where in the brain they are. The study, published in eLife, provides essential insights into how the components of different cells in the brain are altered. These kinds of alterations may be important in our abilities to learn and form memories, […]

Feeling unattractive and dissatisfied with their sexual ability – that is reality for many teenage and young adult cancer survivors. Research from Sahlgrenska Academy, Sweden, now gives a voice to a group that often has a difficult journey back to a normal life. “People in healthcare are afraid to talk about this, but you have to dare and you have […]

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 team of researchers at the University of Oregon has learned more about the mechanism involved in mouse brain white matter changes as it responds to stimulation. In their paper published in Proceedings of the National Academy of Sciences, the group describes the experiments they conducted and what they found. Prior studies of the brain have shown that white matter […]

Cardiovascular diseases are commonly associated with large vessel atherosclerosis. However, accumulating evidence demonstrates disturbances in the small arteries that control tissue perfusion. In particular, under specific conditions such as hypertension, aging, diabetes and obesity, these vessels undergo alteration in size and function, a process known as small artery remodelling. Such changes limit the capacity of these vessels to deliver oxygen […]

Researchers at the Princess Margaret Cancer Centre in Toronto have discovered that epigenetic proteins promote the proliferation of mammary gland stem cells in response to the sex hormone progesterone. The study, which will be published June 19 in the Journal of Cell Biology, suggests that inhibiting these proteins with drugs could prevent the development of breast cancer in women at […]

Keyhole surgery for heart valve repair may trump robotic surgery, because it is associated with lower rates of subsequent heart flutter and blood transfusions, and a shorter hospital stay, reveals research looking at the pros and cons of different surgical approaches, published online in the journal Heart. But as keyhole, robotic, and conventional surgery are all very safe and effective, […]

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 […]

There is no treatment yet for dementia; but one day, a family doctor could prescribe a specific diet, an exercise regime, music or language lessons, or documentary discussion groups as treatments to ward off the disease. Canadian researchers are recruiting older adults across Toronto and Montreal to explore the benefits of different types of brain training and lifestyle interventions for […]
