Stress Activates Brain Regions Linked to Alcohol Use Disorder, Differently for Women Than Men
When exposed to stress, people with alcohol use disorder engage parts of the brain associated with both stress and addiction, which may cause them to drink or crave alcohol after a stressful experience, suggest the authors of a study published in Alcohol: Clinical and Experimental Research.
Skipping Breakfast May Compromise the Immune System
Mount Sinai study shows fasting can trigger a negative effect on fighting infection on a cellular level in mouse models
New UCI-led study shows repeated stress accelerates aging of the eye
New research from the University of California, Irvine, suggests aging is an important component of retinal ganglion cell death in glaucoma, and that novel pathways can be targeted when designing new treatments for glaucoma patients.
‘Extreme’ Plants Grow Faster in the Face of Stress
To understand how plants respond to environmental stresses, researchers examined the genes regulated by the stress hormone abscisic acid. Specifically, they examined how these genes differ between plants that are sensitive or resistant to high levels of salt in the soil. The study found that stress hormones do not always act as growth inhibiting signals.
New insight in patient response to surgical disruption in life-saving hormones
Research by experts at the Universities of Birmingham and Bristol, published today in Royal Society Interface, shows cardiac surgery causes major dynamic changes in concentration of ACTH and cortisol, as well as their pattern of secretion.
Using novel mathematical techniques, researchers developed a model of HPA axis activity that predicts the physiological mechanisms responsible for different patterns of cortisol secretion.
‘Virtual nature’ experiences reduce stress in prisons
For people who are in jails or prisons, experiencing nature virtually is usually their only option. A new study from University of Utah researchers finds that exposure to nature imagery or nature sounds decreased physiological signs of stress in the incarcerated, and spurred their interest in learning more about the habitats they experienced. The researchers also found that, in general, people didn’t strongly prefer visual to auditory nature experiences.
Signals from muscle protect from dementia
How do different parts of the body communicate? Scientists at St. Jude are studying how signals sent from skeletal muscle affect the brain.
