Clogged brain drains may signal early Alzheimer's risk

"Drains" in the brain, responsible for clearing toxic waste in the organ, tend to get clogged up in people who show signs of developing Alzheimer's disease, a study by researchers from Nanyang Technological University, Singapore (NTU Singapore) has discovered.

Blocking mir-21 shows promise for slowing bladder cancer growth

Bladder cancer ranks among the ten most common types of cancer worldwide. The main treatment is bladder removal surgery, and despite advances in systemic therapies, recurrence is frequent in the most aggressive forms of the disease.

New antibody strategy shows promise for halting cyst growth in polycystic kidney disease

Polycystic kidney disease (PKD) is a debilitating hereditary condition in which fluid-filled sacs form and proliferate in the kidneys. Over time, the painful, growing cysts rob the organs of their function, often leading to dialysis in advanced cases.

Trial investigates how quickly human milk responds to common plant based meat swaps

Replacing beef with a plant based beef substitute for six days changed the fatty acid composition of human milk, increasing medium chain saturated fats and lowering key long chain polyunsaturated fats such as arachidonic acid. These biochemical shifts occurred without changes in maternal weight, appetite, glucose patterns or infant milk intake.

Tirzepatide reveals a brain signal that predicts returning food preoccupation

Researchers implanted electrodes in the human nucleus accumbens to track brain activity during severe food preoccupation in an individual taking tirzepatide. They found that a delta–theta biomarker disappeared during symptom-free periods and re-emerged weeks before relapse, suggesting a possible neural marker of vulnerability to dysregulated eating.
