Gut hormone blocks brain cell formation and is linked to Parkinson’s dementia

A gut hormone, ghrelin, is a key regulator of new nerve cells in the adult brain, a Swansea-led research team has discovered. It could help pave the way for new drugs to treat dementia in patients with Parkinson’s Disease. Blood-borne factors such as hormones regulate the process of brain cell formation—known as neurogenesis—and cognition in […]

Updated CPR guidelines tackle health disparities management of opioid-related emergencies

The recovery phase following cardiac arrest continues long after hospitalization and is now included as a key link in the Chain of Survival, a widely adopted series of critical actions that work to maximize the chance of someone surviving cardiac arrest, according to the “2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency […]

Congress must clarify limits of gene-editing technologies

Genome editing of human embryos represents one of the most contentious potential scientific applications today. But what if geneticists could sidestep the controversy by editing sperm and eggs instead? According to a new paper co-written by a University of Illinois at Urbana-Champaign legal expert who studies the ethical and policy implications of advanced biotechnologies, how […]

Diagnosing Parkinson’s disease with skin samples could lead to earlier detection

New research shows a simple skin test can accurately identify Parkinson’s disease, demonstrating for the first time the feasibility of the method. Currently diagnosed by clinical signs and symptoms but only definitively diagnosed at autopsy, Parkinson’s disease is commonly misdiagnosed early in the disease course, complicating clinical trials of potential treatments. The study, published in […]

Study discovers potential target for treating aggressive cancer cells

As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges. One is intratumor heterogeneity—the presence of multiple kinds of cancer cells within the same tumor. Often, these “mosaic” tumors include cells, such as polyploidal giant cancer cells, that have evolved to become aggressive and resistant to chemotherapy […]
