Medical Xpress / Women show greater tau buildup and faster cognitive decline than men in Alzheimer's
Tau proteins act like the brain's maintenance crew, helping maintain the structure and proper function of brain cells. In neurodegenerative diseases such as Alzheimer's, the tau proteins can form tangles that disrupt normal ...
Medical Xpress / Superagers' brains have a 'resilience signature,' and it's all about neuron growth
Brains of older adults with super-healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington. Researchers found that the brains ...
Medical Xpress / Cell signaling step sharpens understanding of how the body responds to exercise's energy demands
Researchers have investigated the role of a certain enzyme in regulating energy in muscle and exercise performance for decades, but a new study by Virginia Tech scientists has identified more precisely than ever how this ...
Medical Xpress / Neurosurgeons are really good at removing brain tumors—they're about to get even better
When removing cancerous tissue in the brain, neurosurgeons often use "awake brain mapping" to minimize the risk of causing unintended disruptions to a patient's quality of life while removing as much tumor as possible. This ...
Medical Xpress / Dry eye often precedes autoimmune disease diagnosis, new study finds
Frequent dry eyes may signal more than simple irritation and could be an early warning sign of an autoimmune disease. This symptom has long been associated with Sjögren's Disease, a chronic autoimmune condition in which ...
Medical Xpress / Single daily pill shows promise as replacement for complex, multi-tablet HIV treatment regimens
A new, daily oral tablet that combines two current HIV treatment medications, bictegravir and lenacapavir (BIC/LEN), could effectively replace more complicated HIV treatment regimens used by people living with HIV who are ...
Medical Xpress / Yawns in healthy fetuses might indicate mild distress
Even in the womb, where all oxygen is provided by the parental placenta, fetuses can—and do—yawn. More yawns during observation were associated with a lower weight at birth—potentially indicating mild fetal stress in ...
Medical Xpress / Black Americans face increasingly higher risk of gun homicide death than white Americans
Firearm homicide death rates have long been disproportionately higher for Black Americans compared to white Americans, and a new analysis across 45 years suggests that in recent years, this disparity has grown. Alex Knorre ...
Medical Xpress / Scientists sharpen genetic maps to help pinpoint DNA changes that influence human health traits and disease risk
Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has created high-resolution ...
Medical Xpress / 'Off the shelf' immunotherapy could get a lift from gene-edited natural killer cells
Since scientists first discovered that human immune cells could be modified to become cancer-fighting agents, they've been trying to engineer a cell that's effective against solid tumors, which account for the vast majority ...
Medical Xpress / Gallbladder cancer could soon be detected in blood
Researchers at Tezpur University in Assam, India, working with scientists at the University of Illinois Urbana-Champaign, have identified distinct chemical signatures in blood that could help detect gallbladder cancer earlier. ...
Medical Xpress / Vitamin B7 reveals a new metabolic weak spot in some cancers
A research group at the University of Lausanne (Unil) has identified a new mechanism that exposes the vulnerability of tumor cells when they are deprived of vitamin B7. The ability of cells to adapt to fluctuations in nutrient ...
