Medical Xpress / Researchers reveal potential molecular link between air pollutants and increased risk of Lewy body dementia
A team of researchers at Johns Hopkins Medicine say they have revealed a possible molecular connection between air pollution and an increased risk of developing Lewy body dementia.
Medical Xpress / How brain fluid dynamics drive cancer spread—and ways to fight back
New research has uncovered how cerebrospinal fluid dynamics in the brain play an important role in driving the spread of medulloblastoma, the most common malignant brain tumor in children.
Medical Xpress / Dietary changes could provide a therapeutic avenue for brain cancer
Glioblastomas are the deadliest form of malignant brain tumor, and most patients diagnosed with the disease live only one or two years. In these tumors, normal cells in the brain become aggressive, growing rapidly and invading ...
Medical Xpress / Study shows how smoking drives pancreatic cancer
A new study explains why smokers have a higher chance of developing pancreatic cancer and why they tend to have worse outcomes than nonsmokers.
Medical Xpress / Microscopic pores in brain cells may be key to understanding Parkinson's
A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus University, where researchers ...
Medical Xpress / After early-life stress, astrocytes can affect behavior
Astrocytes in the lateral hypothalamus region of the brain, an area involved in the regulation of sleep and wakefulness, play a key role in neuron activity in mice and affect their behavior, Canadian researchers have found.
Medical Xpress / Scientists look to commercial dyes to help them diagnose dementia
Today, when an aging parent, relative, or friend starts to forget things, a firm diagnosis can be surprisingly elusive.
Medical Xpress / Stem cell scientists unlock blueprint for lab-grown kidney cells with preclinical value
In the lab, it's easier to grow simple balls of cells than complex asymmetrical structures with two distinct ends—like the one million filtering units—nephrons—that make up a human kidney. But new research unveils a ...
Medical Xpress / How the Epstein-Barr virus hooks onto DNA to reorganize genome and drive nasopharyngeal cancer spread
Researchers from the University of Hong Kong have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of the human genome inside ...
Medical Xpress / Squeezing through tiny blood vessels may trigger melanoma cells to spread
Nine of the 10 most common cancer deaths in Australia are caused by solid tumors, but in most cases it's the cancer's spread to other parts of the body—known as metastasis—that proves fatal.
Medical Xpress / Invisible influence: How cultural cognitive biases influence visuomotor adaptations
The process of improving the synchronization between visual perception and motor skills is called visuomotor learning. It entails adaptation of movements based on visual information. This kind of training can help with skill ...
Medical Xpress / Acid-resistant artificial mucus improves gastric wound healing in animals
Hydrogels—materials like gelatin that can absorb and hold water—can aid wound healing and enable slow-release drug delivery, but they usually break down in acidic environments like the stomach.
