Microvascular dysfunction: a common cause of heart failure with preserved pumping capacity

Heart failure is the most common reason for hospitalisation and causes much suffering. Heart failure with preserved ejection fraction, which is one of the two main types of heart failure, lacks scientifically proven treatments and more research is needed to understand how the disease develops and is to be treated. […]

Disappearing into thin air: harnessing oxygen drop could eliminate cancers without harming healthy tissue

Hypoxia arises because tumours often grow faster than their blood supply, causing oxygen deprivation, which forces cancer cells to adapt — this makes their behaviour more aggressive and in turn leads to their spread around the body. The team sought to understand how cancer cells adapt to hypoxic conditions, with […]

Chronic Inflammation Can Trigger Cancers Via Newly Discovered Mechanism

It is well known that extended exposure to the sun’s UV rays can cause DNA mutations that lead to skin cancer. Now new research reveals that inflammation from chronic skin injury can trigger cancer-causing mutations as well by a totally distinct mechanism. The researchers – led by scientists at UC […]

Genetic tools uncover cause of childhood seizure disorder missed by other methods

Early childhood seizures result from a rare disease that begin in the first months of life. Researchers at University of Utah Health have developed high-tech tools to uncover the genetic cause of the most difficult to diagnose cases. The results are available online in the journal Nature Genomic Medicine. “These tools […]

Study shows new technology can predict fatal heart attacks

Researchers at the University of Oxford, working with colleagues in Erlangen, Germany and at the Cleveland Clinic, USA, have developed a new technology based on analysis of computed tomography (CT) coronary angiograms that can flag patients at risk of deadly heart attacks years before they occur. Heart attacks are usually […]

Post-workout muscle building and repair blunted in obese adults, study finds

Obesity is associated with a host of health problems, including heart disease, type 2 diabetes and high blood pressure. According to a new study reported in the Journal of Physiology, obesity also diminishes a person’s ability to build muscle after engaging in resistance exercise. “Several previous studies, including some from […]

Faulty ‘eat-me’ signal may trigger neurodegeneration

The nervous system is a complex network of neurons that coordinates the body by transmission of electrical signals. And just like the power lines that deliver electricity to homes and businesses, the nervous system sometimes needs maintenance. During early development, animals are constantly eliminating unnecessary neuronal material; the nervous systems […]

Protein Modifications that Point to Cancer

Researchers from the University of Zurich can, for the first time, precisely characterize the protein modification ADP-ribosylation for all proteins in a tissue sample. The changes, which are a typical reaction to stress, provide information about the condition of a cell. Together with the University Hospital Zurich, they are now […]

Maple leaf extract could nip skin wrinkles in the bud

Maple trees are best known for their maple syrup and lovely fall foliage. But it turns out that the beauty of those leaves could be skin-deep — and that’s a good thing. Today, scientists report that an extract from the leaves may prevent wrinkles. The scientists had previously studied the […]

New drug could prevent debilitating side effect of cancer treatment

About 50,000 people in the U.S. are diagnosed annually with head, neck, nasal and oral cancers. Most are treated with radiation, and of those, 70-80 percent develop a painful and debilitating side effect called severe oral mucositis (SOM). While some drugs are available to treat SOM once it develops, none […]

Beluga whales and narwhals go through menopause

Scientists have discovered that beluga whales and narwhals go through the menopause – taking the total number of species known to experience this to five. Aside from humans, the species now known to experience menopause are all toothed whales – belugas, narwhals, killer whales and short-finned pilot whales. Almost all […]

One night of sleep loss negatively impacts fat, muscle tissue

Losing just one night of sleep can have a negative impact on human metabolism at the tissue level, according to a study published last week. The findings may explain how long-term shift work and chronic sleep loss can impair metabolism and adversely affect human body composition. Previous studies have shown that the risk […]

MU researchers create specialized delivery methods that could help treat cancer, other disorders

More than 100 years ago, German Nobel laureate Paul Ehrlich popularized the “magic bullet” concept — a method that clinicians might one day use to target invading microbes without harming other parts of the body. Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still […]
