Medical Xpress / New study finds a missing link in how the brain regulates appetite
When the stomach is full, how does the brain know to stop eating? Scientists long assumed the answer lies mainly with neurons, the brain's primary signaling cells. But a new study published in the Proceedings of the National ...
Medical Xpress / Scientists reveal a new way cancer cells survive DNA damage
A cancer drug target already being investigated in clinical trials turns out to be doing something even more consequential than researchers realized. Scientists at Scripps Research have discovered that the enzyme Pol theta ...
Medical Xpress / How childhood dementia begins in brain cells
An Australian-led international research collaboration has delivered a promising breakthrough in the quest to better understand and treat childhood dementia. Recently published in the journal Nature Communications, the study ...
Medical Xpress / Smart MRI molecules developed to detect and treat cancer
Researchers at NYU Abu Dhabi have developed smart molecules that can both detect and treat cancer, offering a safer and more precise approach to care. The research, published in the Journal of the American Chemical Society, ...
Medical Xpress / Scientists test new ways to regrow joints damaged by arthritis
Good news: Scientists may be closer to a new way to treat arthritis.
Medical Xpress / A single enzyme keeps neuroblastoma alive—how to shut it off
The tumor begins before birth. Somewhere in the developing fetus, neural crest cells that should have matured into adrenal tissue or sympathetic ganglia take a wrong turn, and a child is born harboring a malignancy that may ...
Medical Xpress / Treating tumors independently of oxygen: Photodynamic therapy uses hydrogen peroxide instead
Photodynamic treatment of cancer is based on administering an initially inactive substance that is only activated in the tumor via targeted light irradiation. It then generates reactive oxygen species that kill the cancer ...
Medical Xpress / A new add-on for combat PTSD treatment: MRI-guided TMS significantly reduces symptoms in clinical trial
An advanced version of a procedure using magnetic fields to stimulate brain nerve cells in treating depression was significantly effective for 85% of active military and veterans suffering from combat post-traumatic stress ...
Medical Xpress / A new AI model could help doctors detect lung cancer earlier
Lung cancer remains the leading cause of cancer-related deaths worldwide, accounting for nearly one in five cancer deaths—around 1.8 million lives lost each year. One of the main reasons is late diagnosis: in its early stages, ...
Medical Xpress / Molecular map could unlock new treatments for heart and lung diseases
Scientists have created a new "molecular map" uncovering how an important human receptor involved in blood clotting and inflammation works—an advance that could help us design better drugs for conditions such as pulmonary ...
Medical Xpress / A better way to see how brain cells falter in disease
To gain better insight into what's happening in the brain, researchers examine the molecules produced by brain cells, including RNA and proteins. But existing methods for molecular profiling don't always capture the cells' ...
Medical Xpress / Depression's hidden cost: Why earnings can drop before diagnosis and keep falling
A diagnosis of depression in connection with hospital treatment can have long-term consequences for personal finances. This is shown in a new registry-based study from the Department of Public Health, University of Southern ...
