- Gene protects adults abused as children from depression
02-04-2008 · EurekAlert!
Some forms of a gene that controls the body's response to stress hormones appear to protect adults who were abused in childhood from depression, psychiatrists have found. People who had been abused as children and who carried the most protective forms of the gene, called corticotropin-releasing hormone receptor one, had markedly lower measures of depression, compared with people with less protective forms.

- Altered sex hormone levels, higher body temp affects sleep quality in postmenopausal women
12-01-2007 · EurekAlert!
In an examination of potential relationships between objective sleep measures, nocturnal sex hormone levels, and the nocturnal course of body temperature of older postmenopausal women, a study published in the Dec. 1 issue of the journal Sleep finds that altered levels of both sex hormones and gonadotropins may contribute to sleep disturbance in older postmenopausal women and confirm the results of previous studies indicating that higher body temperature is associated with poorer sleep quality.

- Circadian clock controls plant growth hormone
08-10-2007 · EurekAlert!
The plant growth hormone auxin is controlled by circadian rhythms within the plant, UC-Davis researchers have found. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.

- First molecular evidence of body's internal clock in controlling blood pressure
02-19-2007 · EurekAlert!
It has been known for decades that heart attacks and strokes occur most frequently in the early-morning hours. Now, researchers at Penn have provided the first evidence for the role of our body’s internal molecular clock in controlling blood pressure and a mechanism by which this occurs. This report points to the novel possibility of modifying blood pressure and the early-morning risk of heart attack.

- Hormone that signals fullness also curbs fast food consumption and tendency to binge eat
06-07-2007 · EurekAlert!
The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets. The findings on fast food consumption and binge eating tendencies are based on a six-week research study of 88 obese individuals.

- Studies find stable sleep patterns and regular routines may improve outcomes in bipolar disorder
12-08-2007 · EurekAlert!
Bipolar disorder, commonly known as manic-depressive disorder, is highly influenced by the circadian system -- the body's internal clock -- and a specific kind of psychotherapy may help decrease irregularities in the circadian system that can trigger key symptoms of bipolar disorder, according to a study presented today at the American College of Neuropsychopharmacology Annual Meeting.
