Baboon matriarchs enjoy less stress

A Duke University-led study found that alpha female baboons have significantly lower levels of glucocorticoids, hormones produced in response to stress. The researchers discovered that higher-ranking females get preferential treatment, leading to faster-growing babies and increased survival rates.

Social bonds in adulthood don't mediate early life trauma

A study of wild female baboons found that early life trauma had a significant negative impact on adult glucocorticoid concentrations, which are a measure of health. Despite having strong social relationships as adults, the stress hormone levels were still significantly higher in those who experienced trauma in early life.

What and how much we eat might change our internal clocks and hormone responses

A high-caloric diet alters the time-of-day dependent metabolic cycle in mice, suggesting lean and obese patients may respond differently to steroid therapy. The study also highlights the biological function of daily hormone secretion cycles and their impact on sugar and fat storage or release by the liver.

ACR Releases Guideline on prevention & treatment of glucocorticoid-induced osteoporosis

The ACR's updated clinical guideline provides recommendations for assessing fracture risk and treatment for adults and special patient populations. For all age groups, the panel strongly recommends optimizing calcium and vitamin D intake and implementing lifestyle modifications to prevent glucocorticoid-induced osteoporosis.

Steroids rapidly restore blood-brain barrier function after blast

Research by Columbia University finds that glucocorticoid treatment restores BBB function within a day of primary blast injury, potentially reducing mandatory rest periods for military personnel. The study's positive results could lead to the development of targeted therapies using steroids to restore BBB integrity after blast injury.

Mother's stress hormone levels may affect fetal growth and long term health of child

A recent study published in The Journal of Physiology found that increased stress hormone levels in pregnant mice can lead to overeating and reduced fetal growth. However, this effect is not seen when the hormone is administered earlier in pregnancy or when the diet is restricted. The researchers believe that maternal glucocorticoid le...

Stress during pregnancy can affect fetal development

A study published in The Journal of Physiology found that high stress levels in pregnant mice led to increased cortisol levels, causing mothers to eat more but reducing placental glucose transport. This can result in decreased fetal weight and long-term metabolic health implications for children.

LncRNAs have been found to regulate gene expression in various diseases, including brachydactyly and HELLP syndrome. Additionally, research on obesity has shown that early genetic intervention can rescue mice from obesity-induced metabolic disorders. Furthermore, editing mistakes in miR-376 cluster have been linked to invasive brain tu...

Taking oral glucocorticoids for 3 months or longer? Beware of osteoporosis!

Long-term oral glucocorticoid therapy is associated with a significant risk of bone loss and fractures, particularly in older adults and those with higher doses. To mitigate this risk, patients should take preventive measures such as maintaining adequate calcium and protein intake, exercising regularly, and getting enough vitamin D.

Researchers study parenting behaviors of stressed-out birds

Biologists Fran Bonier and Ignacio Moore investigate how stressed bird parents care for their young and respond to environmental challenges. The study aims to determine whether glucocorticoid levels affect bird parenting behaviors, with potential implications for understanding the effects of stress on organisms and evolution.
