Corticosterone is a 21 carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands.
Fire can put a tropical songbird's sex life on ice. Following habitat-destroying wildfires in Australia, researchers found that many male red-backed fairywrens failed to molt into their red-and-black ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers.
Birds play an underrecognized role in spreading tickborne disease due to their capacity for long-distance travel and tendency to split their time in different parts of the world - patterns that are shifting due to climate change.
Female rats that inhaled vaporized cannabis daily for a month developed a blunted physiological response to stress, according to a new study by Washington State University researchers.
This work has investigated the long-term consequences of stress experienced at this critical period of life in rodents, in collaboration with the Behavioural Genetics laboratory at the Brain and Mind Institute of the Federal Polytechnic School of Lausanne (Switzerland), led by the Spanish researcher Carmen Sandi.
New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function.
A new study has shown that the compound resveratrol found in red wine demonstrates stress relieving effects in anxiety and depression. This could be due to resveratrol’s ability to control an enzyme in the brain that is liked to stress say the researchers from the University at Buffalo in collaboration with Xuzhou Medical University in China.
Like to unwind with a glass of red wine after a stressful day? Don't give alcohol all the credit.
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.
