Corticosterone is a 21 carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands.
A team of Penn State and University of Puerto Rico School of Medicine researchers is attempting to answer a question that has long puzzled experts: Why do some individuals suffer post-traumatic stress disorder (PTSD) after experiencing trauma, and others do not?
In a new study, Yale researchers offer insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. Their findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for developing future weight-loss treatments, they said.
It has long been thought that stress contributes to cancer progression. Scientists from the University of Basel and the University Hospital of Basel have deciphered the molecular mechanisms linking breast cancer metastasis with increased stress hormones.
The first and most distinct consequence of daily mild stress is an increase in rapid-eye-movement (REM) sleep, a new study in the journal PNAS reports. The research also demonstrated that this increase is associated with genes involved in cell death and survival.
Having ancestors who were frequently exposed to stressors can improve one's own immune response to stressors, according to Penn State researchers.
Researchers with the Veterans Affairs Portland Health Care System and Oregon Health & Sciences University found that a history of binge drinking made male and female mice react differently to traumatic stress.
It seems "hangry" isn't just a made-up term. University of Guelph researchers have revealed that the sudden drop in glucose we experience when we are hungry can impact our mood.
People with multiple sclerosis (MS) can find an abundance of conflicting advice suggesting that special diets – everything from avoiding processed foods to going low-carb – will ease their symptoms. But the evidence is scanty that dietary changes can improve fatigue or other MS symptoms.
Deep within aquatic ecosystems all over the world, certain toad species have managed to survive warmer and drier climate change. But the method behind their metamorphic adaptation to environmental change over time has long puzzled scientists -- until now.
New research led by The Ohio State University Wexner Medical Center found a potential therapeutic strategy to prevent infections in patients with spinal cord injuries.
Everyone empirically knows that stressful events certainly affect sound sleep. Scientists in the Japanese sleep institute found that the active component rich in sugarcane and other natural products may ameliorate stress and help having sound sleep.
Traumatic brain injuries affect the body's stress axis differently in female and male mice, according to research presented at the Endocrine Society's 99th annual meeting, ENDO 2017, in Orlando, Fla.
UC biologists have turned to amphibian sources -- specifically frogs and tadpoles -- to help shed light on how early stressors in the womb and shortly after birth may play a part in the onset of adult diseases such as diabetes and cardiovascular disease.
While male and female mice have similar responses to physical stress, research from the Hotchkiss Brain Institute at the University of Calgary, Canada, suggests females, not males, feel stressed when alone.
A tiny RNA appears to play a role in producing major depression, the mental disorder that affects as many as 250 million people a year worldwide.
Scientists from the RIKEN Center for Life Science Technology in Japan have used a new non-invasive PET scanning technique to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to be particularly affected by depression.
Rats given midazolam, an anti-anxiety medication, were less likely to free trapped companions because the drug lessened their empathy, according to a new study by University of Chicago neuroscientists.
Evidence is mounting that a diet mimicking the effects of fasting has health benefits beyond weight loss, with a new USC-led study indicating that it may reduce symptoms of multiple sclerosis.
Drinking during early to mid-adolescence can lead to vulnerability to chronic stress, according to new research from Binghamton University, State University of New York.
Scientists from the RIKEN Brain Science Institute have shown that a mouse strain with a mutation that leads to dysfunction of mitochondria--the "powerhouses" that provide energy to cells--spontaneously undergo periodic episodes of depression-like behavior that resemble those in human. Through this research, published in Molecular Psychiatry, the scientists uncovered a link between depression and the paraventricular thalamus, a region of the brain not previously tied to depression.
