Regulation of cortisol bioavailability—effects on hormone measurement and action

Clinical assessment of the hypothalamic–pituitary–adrenal axis relies on measuring total serum cortisol levels. However, most circulating cortisol is bound to carrier proteins and only free cortis...

Flavonoids tied to less stomach cancer in women

NEW YORK (Reuters Health) - Moderate amounts of dietary flavonoids may be linked to a lower stomach cancer risk in women, but not men, according to a new study from Europe.

Stress Hormones Lower The Risk Of PTSD

Increasing the presence of glucocorticoids may decrease the development of post-traumatic stress disorder (PTSD). Glucocorticoids, including cortisol, are a group of stress hormones that increase afte...

Stress hormones: Good or bad for posttraumatic stress disorder risk?

Glucocorticoids, a group of hormones that includes cortisol, are considered stress hormones because their levels increase following stress. When their relationship to stress was first identified, it w...

New research on flavonoids and nutritional health in older adults from JONGG

Routledge Journals is pleased to announce a Special Issue from the Journal of Nutrition in Gerontology and Geriatrics focusing on the impact of flavonoids on the nutritional health of older adults.

Cortisol in Hair May Reveal CV Risk (CME/CE)

(MedPage Today) -- Levels of cortisol in the hair that remained elevated over time signaled an increased risk of cardiovascular disease, researchers found.

Hair Cortisol Reveals Stress, Predicts CVD in Seniors

Seniors with high levels of the stress hormone cortisol in their hair were more likely to have a history of cardiovascular disease; the risk was similar to having hypertension. Medscape Medical...

Exercise affects reproductive ability in horses

(American Society of Animal Science) Results from the study showed that exercise induced greater cortisol concentrations in horses. Cortisol has been shown to have effects on reproduction.

Mixture effects of dietary flavonoids on steroid hormone synthesis in the human adrenocortical H295R cell line.

Humans are exposed to a mixture of dietary flavonoids with a variety of potential beneficial and harmful effects. Flavonoids are endocrine disruptors, acting both at receptor level and by interfering...

Hair cortisol levels as a retrospective marker of hypothalamic-pituitary axis activity throughout pregnancy: Comparison to salivary cortisol.

Maternal stress during pregnancy is associated with negative maternal/child outcomes. One potential biomarker of the maternal stress response is cortisol, a product of activity of the hypothalamic-pit...

Use of hair cortisol analysis to detect hypercortisolism during active drinking phases in alcohol-dependent individuals.

The assessment of cortisol levels in human hair has recently been suggested to provide a retrospective index of cumulative cortisol exposure over periods of up to six months. The current study examine...

Correlation of cortisol in 1-cm hair segment with salivary cortisol in human: hair cortisol as an endogenous biomarker.

Abstract Background: Cortisol level in human hair would be an endogenous biomarker for the retrospective assessment of long-term central hypothalamo-pituitary-adrenal activity. However, no direct evid...

Analysis of cortisol, cortisone and dexamethasone in human serum using liquid chromatography tandem mass spectrometry and assessment of cortisol: Cortisone ratios in patients with impaired kidney function.

We developed a high sensitivity method for simultaneous measurement of cortisol, cortisone and dexamethasone. Using this method, we compared concentrations of cortisol, cortisone and their ratios in s...
