To ensure all living animals and humans avoid as much danger as possible, they have an inbuilt ‘fight-or-flight’ response. The fight-or-flight response, also known as the acute stress response (ASR), … Continue Reading Bone not adrenaline drives fight or flight response.
One in 15 adults has moderate to severe obstructive sleep apnea (OSA), a disorder in which a person’s breathing is frequently interrupted during sleep, as many as 30 times per … Continue Reading Neuroimaging confirms that sleep apnea takes a toll on brain function.
It’s long been known that excess iron is found in the brains of patients with Parkinson’s disease (PD), an incurable neurodegenerative condition that affects motor function. However, the mechanism by … Continue Reading Researchers identify the neurogenetic basis of excess iron in Parkinson’s disease.
Stress-induced Cardiomyopathy (SIC) is a temporary condition where a person’s heart muscle becomes suddenly weakened or ‘stunned’ and the left ventricle changes shape. Patients with SIC generally show no symptoms … Continue Reading Researchers identify rare genes linked to stress-triggered heart disease.
Sigma receptors, particularly the sigma-1 receptor subtype, which are expressed in both neurons and glia of multiple regions within the central nervous system, are a unique class of intracellular proteins … Continue Reading Neuroprotective receptor found to have important role in support cells for the retina.
When cells are normal and unstressed, the molecule keeps transcription moving so that genes are ‘expressed’ and RNA is jotted down more quickly. When cells are stressed and transcription runs … Continue Reading Researchers identify key molecule which halts transcription of cell’s genetic code.
Scientists from the Institut Pasteur, CNRS, Institut Gustave Roussy and CEA, have succeeded in restoring normal activity in cells isolated from patients with the premature aging disease Cockayne syndrome. They … Continue Reading Researchers identify and correct premature aging in diseased cells.
A research collaboration between the universities of Oslo and Aarhus has resulted in the development of a new method with diagnostic potential. The new method that combines phase extraction with … Continue Reading New technique developed for determining possible stress marker in blood samples.
Oxidative stress has become a major topic; not only is it implicated in many diseases, it may even be one of their causes. Other environmental influences besides UV radiation can … Continue Reading Researchers use precision medicine to prove the effectiveness of Vitamin E as an antioxidant.
The ability to learn associations between events is critical for survival, but it has not been clear how different pieces of information stored in memory may be linked together by … Continue Reading Researchers optogenetically create artificial link between unrelated memories.
In a study of more than 8,000 veterans living in Hawaii and the Pacific Islands, researchers from Ohio State University, University of Minnesota, and The Department of Veterans Affairs found those … Continue Reading First large-scale longitudinal study links PTSD to heart disease.
A protein that helps embryonic stem cells retain their identity also promotes DNA repair, according to a study in The Journal of Cell Biology. The findings raise the possibility that … Continue Reading Researchers identify protein responsible for DNA repair at a stem cell level.
Stating that sleep is an essential biological process seems as obvious as saying that the sun rises every morning. Yet, researchers’ understanding of the molecular mechanisms underlying the effects of … Continue Reading Lipidomics study identifies common biomarkers of sleep debt in humans and rats.
Researchers have known that transplanted human umbilical cord cells (HUCBCs) can have a restorative effect on the brain and brain function following a stroke. However, just how the cells exert … Continue Reading Precision medicine used to counteract oxidative stress in stroke animal model.
Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism. Scientists at Rice … Continue Reading Nano-antioxidants shown to have ‘enormous’ capability to quench superoxides after traumatic injury.
Why do some people develop post-traumatic stress disorder (PTSD) while others who suffered the same ordeal do not? A new UCLA discovery may shed light on the answer. UCLA scientists … Continue Reading Study identifies two genes that boost risk for post-traumatic stress disorder.
