Medical Xpress / Dopamine deficiency found to drive memory impairment in Alzheimer's disease
Why do memories fade in Alzheimer's disease—and can they be restored? University of California, Irvine researchers have uncovered a key mechanism underlying memory loss, showing for the first time that dopamine dysfunction ...
Medical Xpress / Hidden mosquito viruses emerge as RNA immune signals map global infections
Aedes aegypti, commonly known as the yellow fever mosquito, is a highly adapted, invasive mosquito species recognized as a major global health threat that acts as the primary vector for several severe diseases, most notably ...
Medical Xpress / How a gentler stem cell transplant may move type 1 diabetes treatment closer
A combination blood stem cell and pancreatic islet cell transplant from an immunologically mismatched donor completely prevented or cured type 1 diabetes in mice in a study by Stanford Medicine researchers. Type 1 diabetes ...
Medical Xpress / Gene-screen strategy separates Parkinson's promoters from protectors, revealing new drug targets
A novel strategy that combines computational and experimental approaches has allowed researchers at Baylor College of Medicine and the Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital to distinguish ...
Medical Xpress / Inside lymph nodes, an overlooked cell type quietly directs immune battles in ways that could reshape medicine
The research group of prof. Sanjiv Luther at the department of immunobiology of the University of Lausanne has discovered that a fibroblast subtype is essential for coordinating certain immune cells within lymph nodes. This ...
Medical Xpress / Selection model helps explain why most human pregnancies are singletons
Each month during a woman's menstrual cycle, an ovary prepares 10–20 antral follicles, fluid-filled sacs that hold immature eggs, for maturation. In most cycles, only one follicle is selected to undergo maturation, eventually ...
Medical Xpress / Freeze-dried platelet product slows swelling and bleeding in traumatic brain injuries
A freeze-dried blood product that could be stored for years on ambulances or in remote emergency departments is showing promise at treating traumatic brain injuries. The news comes from a mouse study done by researchers at ...
Medical Xpress / Conversational AI uses trusted medical protocols to help people decide when to seek care
A new type of chatbot could reliably help people decide what to do about their symptoms—and do so based on guidance that is both medically sound and easy to understand. The chatbot could help reduce unnecessary hospital visits ...
Medical Xpress / Astrocytes reveal fragile X pathway tied to seizures and synapse problems
Fragile X syndrome (FXS) is an inherited genetic developmental condition that strongly impacts brain development. Despite the syndrome stemming from an altered genetic code for the single protein fragile X messenger ribonucleoprotein ...
Medical Xpress / Human cell model recreates Alzheimer's-linked tau pathology and synapse loss
Researchers at LMU have developed a human cell model that replicates key mechanisms of neurodegenerative diseases—with potential for novel therapies. The paper is published in the journal Science Translational Medicine.
Medical Xpress / Scientists map how Down syndrome reshapes brain development before birth
Scientists at UCLA have created one of the first cellular-resolution molecular maps detailing how Down syndrome alters human brain development before birth—a resource that resolves longstanding contradictions in the field ...
Medical Xpress / Tiny fiber probe monitors three key biomarkers at once, offering faster patient insight
A new fiber probe developed by researchers at The University of Texas at Austin delivers two major innovations in health monitoring to help both patients around the world and the clinicians who care for them. The probe can ...
