Every year, more than 795,000 people in the United States have a stroke. Of these, approximately 80% lose arm function and as many as 50-60% of this population still experience problems six months later. Traditionally, stroke patients try to regain motor function through physical rehabilitation, where patients re-learn pre-stroke skills, such as eating […]

A new study published in Science, has revealed how the master switch for hunger in the brain, the melanocortin receptor 4 (MC4), works. The research team, including scientists from the Weizmann Institute of Science, Queen Mary University of London and the Hebrew University of Jerusalem, also clarified how this switch is […]

A national, University at Buffalo-led study on genes in pediatric cardiomyopathy demonstrates strong evidence for routine genetic screening in children with the disease. The study, published in the Journal of the American Heart Association, revealed wide variation in screening, with some centres conducting routine genetic testing and others conducting none. […]

The immune response to tuberculosis (TB) differs in adults and newborn babies due to the way immune cells use energy to kick into gear in a bid to kill the bacteria. This fresh discovery – just published in leading journal, Frontiers in Immunology – offers hope for improving treatments for what remains […]

Drugs and vaccines circulate through our vascular system reacting according to their chemical and structural nature. In some cases, their destination is diffuse. In other cases, like cancer treatments, the intended target is highly localized. The effectiveness of a medicine —and how much is needed and the amount of side-effects […]

A University of Alberta researcher is using nanotechnology to improve the effectiveness of chemotherapy treatments for cancer patients and reduce their side effects. Afsaneh Lavasanifar is a professor in the University of Alberta’s Faculty of Pharmacy & Pharmaceutical Sciences and an adjunct professor in the Department of Chemical and Medical Engineering. Her lab develops […]

Experimental Alzheimer’s drugs have shown little success in slowing declines in memory and thinking, leaving scientists searching for explanations. But new research in mice has shown that some investigational Alzheimer’s therapies are more effective when paired with a treatment geared toward improving drainage of fluid — and debris — from […]

Innovative multidisciplinary research at Washington University led to development of 'breakthrough' device. A first-of-its-kind device that helps people disabled by stroke regain significant control over their arm and hand function by using their minds has received market authorization from the Food and Drug Administration (FDA). The IpsiHand Upper Extremity Rehabilitation […]

Brain changes in people with Alzheimer’s disease and in those with mild traumatic brain injuries have significant similarities, a new USC study shows, suggesting new ways to identify patients at high risk for Alzheimer’s. The findings appeared in GeroScience. Traumatic brain injuries, or TBIs, affect over 1.7 million Americans every […]

Enhancing the brain’s lymphatic system when administering immunotherapies may lead to better clinical outcomes for Alzheimer’s disease patients, according to a new study in mice. Results published in Nature suggest that treatments such as the immunotherapies BAN2401 or aducanumab might be more effective when the brain’s lymphatic system can better drain […]

Scientists have made a pivotal breakthrough in understanding the way in which cells communicate with each other. A team of international researchers, including experts from the University of Exeter’s Living Systems Institute, has identified how signalling pathways of Wnt proteins – which orchestrate and control many cell developmental processes – […]

Pioneering research led by experts from the University of Exeter’s Living Systems Institute has provided new insight into formation of the human embryo. The team of researchers discovered an unique regenerative property of cells in the early human embryo. The first tissue to form in the embryo of mammals is […]
