Medical Xpress / Bacteria that can make testosterone: What could that mean for prostate cancer?
Many prostate cancers depend on androgen hormones, including testosterone, to grow. That is why treatments for advanced disease often try to reduce testosterone production or block its effects. Now, scientists have identified ...
Medical Xpress / Atherosclerosis may meet key criteria for autoimmune disease, evidence suggests
In autoimmune diseases, the immune system turns against the body through pathogenic high-affinity B cells or T cells, leading to severe organ damage. Multiple sclerosis (nervous system paralysis), type 1 diabetes (a strong ...
Medical Xpress / How losing the 'guardian of the genome' can damage DNA and drive cancer
A new study finds that when p53, one of the most important cancer-protecting genes, stops working, cells produce too much RNA and consume excessive amounts of the building blocks needed to copy their DNA. This shortage disrupts ...
Medical Xpress / Why scientists are looking to provoke disagreement among AI brain models
When people wanted to create better artificial intelligence, they looked to the brain for inspiration. Now the tables are turning, and researchers are using AI models to better understand the brain. But how do we judge which ...
Medical Xpress / Why beauty feels shared: Brain scans map art's content and pleasure pathways
Stand in front of "Turner's Sun Rising Over Water" (1825–30), and something odd tends to happen. The painting holds you, even though observers might struggle to say why. Maybe it is the color, the balance, the composition ...
Medical Xpress / Targeting mosquitoes reduces flesh-eating ulcer risk in Melbourne trial
Mosquito control in an urban setting can reduce a person's risk of contracting Buruli ulcer by over 80%, finds a new Melbourne-led study.
Medical Xpress / Brain's inhibitory circuits emerge as a potential brake on adult glioma progression
Brain tumors do not grow in isolation. They develop within the highly active environment of the brain, where neurons continuously exchange electrical and chemical signals. While previous studies have shown that neuronal activity ...
Medical Xpress / Mitochondrial DNA mutations may help turn aging hearts toward failure
Researchers at Karolinska Institutet have shown that mutations in mitochondrial DNA (mtDNA), which accumulate in many tissues as we age, can actively contribute to impaired heart function. Until now, it has been difficult ...
Medical Xpress / Disabling a gene brake in pancreatic cells unlocks insulin-producing potential
Type 1 and 2 diabetes are ultimately caused by a shortage of beta (β) cells, which are present in the pancreas and produce insulin to control blood sugar. Researchers from Harvard Medical School found that they can tweak ...
Medical Xpress / Self-control matures later than working memory in adolescence, large analysis finds
Adolescence, the developmental phase between childhood and adulthood, is marked by substantial mental, emotional and social changes. Past psychological studies suggest that during this stage, humans gradually acquire greater ...
Medical Xpress / New data presented on the use of coronary artery calcium for cardiovascular risk assessment
There was no difference in major cardiovascular events when statin initiation was based on coronary artery calcium compared with traditional risk factor assessment, according to results presented in a Hot Line session today ...
Medical Xpress / Brain signaling mechanism may explain clozapine weight gain
Researchers at UT Southwestern Medical Center have identified a key brain signaling pathway that appears to drive the substantial weight gain often associated with clozapine, a widely used antipsychotic medication. The preclinical ...
