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 / A global fertility reversal is unfolding, and it could upend who becomes parent in decades ahead
With few exceptions, birth rates are falling worldwide. What does this mean? Put simply, the fertility rate describes the average number of children a woman is expected to have over the course of her life, if exposed to the ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / Blood vessels in fat tissue may help drive obesity and type 2 diabetes
Adipose tissue is far more important for our health than many may realize. It does not merely function as an energy store, but as an active tissue that continuously communicates with the rest of the body. This communication ...
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 / 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, ...
