Social stress linked to visceral fat, atherosclerosis

A new study done by researchers at Wake Forest University School of Medicine shows that social stress could be an important precursor to heart disease by causing the body to deposit more fat in the abdominal cavity, speeding the harmful buildup of plaque in blood vessels, a stepping stone to the number one cause of death in the world.

Workplace meditation and yoga lowers stress

Twenty minutes per day of guided workplace meditation and yoga combined with six weekly group sessions can lower feelings of stress by more than 10 percent and improve sleep quality in sedentary office employees, a pilot study suggests.

Acute stress improves working memory

Day after day of chronic stress will wear a person down physically and mentally. But new research suggests that the acute stress produced by a brief run-in with a stressful scenario acts on a key brain region controlling emotion and cognition, temporarily improving learning and memory.

Effect of sunlight exposure on cognitive function among depressed and non-depressed participants

A lack of sunlight is associated with reduced cognitive function among depressed people. Researchers writing in BioMed Central's open access journal Environmental Health used weather data from NASA satellites to measure sunlight exposure across the United States and linked this information to the prevalence of cognitive impairment in depressed people.

Discovery of key event in prostate cancer progression

A study led by researchers at the Ohio State University Comprehensive Cancer Center and Dana-Farber Cancer Institute reveals how late-stage, hormone-independent prostate tumors gain the ability to grow without need of hormones.

Short stressful events may improve working memory

Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory.

Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

Scientists discover 27 genes associated with Asperger's syndrome, autistic traits and empathy

Scientists from the University of Cambridge have identified 27 genes that are associated with either Asperger Syndrome (AS) and/or autistic traits and/or empathy. The research will be published tomorrow in the journal Autism Research. This is the first candidate gene study of its kind.

Researchers grow immature egg cells in the laboratory for 30 days - could sustain cancer patients’ fertility

Researchers funded by the National Institutes of Health have completed a critical first step in the eventual development of a technique to retain fertility in women with cancer who require treatments that might otherwise make them unable to have children.

Ethicists urge inclusion of pregnant women in Federal child-health study

A team of ethicists from Johns Hopkins, Duke and Georgetown universities is urging organizers of a recently begun $3 billion decades-long study of children's health to immediately add provisions to look at the health and medical profiles of the children's mothers during their pregnancies.

Two reproductive factors are important predictors of death from ovarian cancer

Researchers from the Centers for Disease Control and Prevention (CDC) found that survival among women with ovarian cancer is influenced by age of menarche and total number of lifetime ovulatory cycles.

Relationship between migraine history and breast cancer risk among premenopausal and postmenopausal women

The relationship between migraine headaches in women and a significant reduction in breast cancer risk has been confirmed in a follow-on study to landmark research published last year and conducted by scientists at Fred Hutchinson Cancer Research Center. The new study found a 26 percent reduced risk of breast cancer among both premenopausal and postmenopausal women with a clinical diagnosis of migraines.

Discovery of second gene linked to familial testicular cancer

Specific variations or mutations in a particular can gene raise a man's risk of familial, or inherited, testicular germ-cell cancer, the most common form of this disease, according to new research by scientists at the National Institutes of Health.

First baby born after new ovarian transplant technique

A new technique for transplanting the ovaries of women who have lost their fertility as a result of cancer treatment was outlined to the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June).

Delay in diagnosis of menopause-like condition in young women linked to low bone density

Women and young girls who experience delays in diagnosing a premature, menopause-like condition face increased risk of low bone density, according to new research by scientists at the National Institutes of Health. A delay in diagnosing the condition, called primary ovarian insufficiency, may make women more susceptible to osteoporosis and fractures later in life, the researchers concluded.

“Life force” linked to body’s ability to withstand stress

Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may indicate that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.

New findings on how stress causes sexual dysfunction and infertility

University of California, Berkeley, researchers have found what they think is a critical and, until now, missing piece of the puzzle about how stress causes sexual dysfunction and infertility.

Could hormones explain gender differences in neurological disease?

Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT).

Social moms make better moms, at least in baboons

Female baboons who have strong social relationships with other females give birth to offspring who are much more likely to survive to adulthood than baboons reared by less social mothers, according to a new study by researchers at the University of Pennsylvania, the University of California, Los Angeles, and others.

A new method for breast cancer biomarker discovery

Three researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.
