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 / 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 / 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 / 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 / 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 / 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 ...
Medical Xpress / Genetic test forecasts chemo response in breast cancer
A new study from Karolinska Institutet shows that gene analysis of breast cancer tumors can identify patients who do not benefit from chemotherapy given before surgery. The findings, published in the journal Nature Communications, ...
Medical Xpress / ADHD-related traits may intensify chronic pain through anxiety and negative thinking
A new study, led by researchers from the University of Tokyo, involving nearly 1,000 patients in Japan suggests that attention deficit hyperactivity disorder (ADHD)-related traits may be associated with and may contribute ...
Medical Xpress / 3D DNA switch in brown fat could reshape obesity and diabetes treatment
Most fat stores energy; the body's brown fat does the opposite. Unlike the white fat that accumulates just under our skin, brown fat burns calories and glucose to generate heat. Formally known as brown adipose tissue, it ...
Medical Xpress / How red blood cells keep making hemoglobin under stress could reshape anemia treatment
Scientists have long been puzzled by how maturing red blood cells manage to produce all the hemoglobin they need to carry oxygen to tissues, even after shedding the vital structures they need to produce it.
Medical Xpress / Two-faced protein discovery may explain why leukemia drugs fail or succeed
A KAIST research team has identified the real reason why anticancer drugs kill cancer cells—targeted anticancer therapies do not simply block cancer proteins but rather shut down the "protein factories" inside the cells, ...
