Scientists determine structure of brain receptor implicated in epilepsy and PMT
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have published new research in the journal Molecular Pharmacology identifying the structure of a receptor in the brain implicated in conditions such as epilepsy and pre-menstrual tension. The same receptor has... view more (2008-03-10)

High levels of estrogen associated with breast cancer recurrence
Women whose breast cancer came back after treatment had almost twice as much estrogen in their blood than did women who remained cancer-free - despite treatment with anti-estrogen drugs in a majority of the women -according to researchers in a study published in the March issue of Cancer... view more (2008-03-06)

Cancer risk slightly higher for women in discontinued hormone treatment trial
A follow up study of participants in the Women's Health Initiative (WHI) clinical trial led by a University of North Carolina at Chapel Hill researcher has found that women who were taking the combined hormone therapy of estrogen plus progestin may have an increased risk of cancer since the... view more (2008-03-05)

Einstein researchers discover gene mutations linked to longer lifespans
Mutations in genes governing an important cell-signaling pathway influence human longevity, scientists at the Albert Einstein College of Medicine of Yeshiva University have found.   view more (2008-03-05)

Neurons use chemical 'chords' to shape signaling
Researchers have discovered that neurons can use two different neurotransmitters that target the same receptor on a receiving neuron to shape the transmission of a nerve impulse.   view more (2008-02-28)

Scripps scientists studying sepsis in mice find potential drug targets for deadly disease
"We have identified a key connection of signaling pathways in the cascade of events leading to sepsis. This defines a crucial point where the immune system spirals out of control to cause severe sepsis and where there is an opportunity for therapeutic intervention," says Scripps Research... view more (2008-02-28)

Breast cancer subtypes linked to survival from secondary brain tumors
Screening breast cancers for three receptors could help doctors predict the likely survival of patients with brain metastases.   view more (2008-02-28)

Researchers collaborate to find new vaccine technology decreases E. coli in beef cattle
Despite millions of dollars spent on food safety research over the last 10 years, ground beef recalls due to E. coli O157:H7 were higher in 2007 than in 2006, according to researchers from Kansas State University and West Texas A&M University. E. coli O157:H7 has been linked to foodborne... view more (2008-02-28)

Polluted prey causes wild birds to change their tune
Considerable attention has been paid to the effects of endocrine disrupting chemicals in aquatic environments, but rather less attention has been given to routes of contamination on land.   view more (2008-02-27)

LA BioMed study finds hormone therapy increases frequency of abnormal mammograms, breast biopsies
Combined hormone therapy appears to increase the risk that women will have abnormal mammograms and breast biopsies, and it may decrease the effectiveness of both methods for detecting breast cancer.   view more (2008-02-26)

Columbia geneticists uncover new gene involved in determining hair texture and density in humans
A Columbia University Medical Center research team has discovered a new gene involved in determining hair texture in humans.   view more (2008-02-26)

Getting to the roots of hair loss
A healthy individual loses around a hundred hairs a day. Nothing to worry about as long as they are constantly replaced and the losses occur evenly around the whole scalp.   view more (2008-02-25)

Researchers explore the antidepressant effects of ketamine
Drug treatments for depression can take many weeks for the beneficial effects to emerge. The excruciating and disabling nature of depression highlights the urgency of developing treatments that act more rapidly.   view more (2008-02-22)

AMD discovery: New hope for treatment of vision loss
Scientists have won a major battle in the fight against age-related macular degeneration, or AMD, a blinding eye disease that affects millions of people. An international team, led by researchers at Sainte-Justine Hospital and the Université de Montréal, has identified the deficient... view more (2008-02-21)

Another way to grow blood vessels
Researchers at Dana-Farber Cancer Institute have found a previously unknown molecular pathway in mice that spurs the growth of new blood vessels when body parts are jeopardized by poor circulation.   view more (2008-02-21)

Newly discovered role of thyroid hormone during pregnancy
Thyroid hormone deficiencies in early pregnancy can cause locomotor underdevelopment in the child, according to research from the Swedish medical university Karolinska Institutet. The results bring new insights into brain development and could affect routine pregnancy testing.   view more (2008-02-20)

Vaccine/antibody therapy effective, milder side effects in melanoma and ovarian cancer
One of the shortcomings of a therapy that uses millions of identical antibodies to boost the immune system's attack on cancer cells is that many patients whose tumors recede in response to the treatment also experience serious inflammatory problems, such as severe diarrhea and rashes.   view more (2008-02-19)

Protein maintains cross talk between cells that control hair growth
Genes, it turns out, are only as active as the signals that turn them on and off. Now scientists from Rockefeller University and the Howard Hughes Institute have identified the signaling molecule that ratchets up and clamps down the activity of key genes in dermal papilla, a type of skin cell whose... view more (2008-02-15)

How DDT metabolite disrupts breast cancer cells
Research has shown that the main metabolite of the insecticide DDT could be associated with aggressive breast cancer tumours, but there has been no explanation for this observation to date. Now a report published in the open access journal Breast Cancer Research shows how DDT could act to disrupt... view more (2008-02-14)

Patient with rare disorder responds to cancer drug
A rare disorder caused by an excess of two types of immune cells-the mast cell found in various tissues and its blood-based twin, the basophil-has successfully been treated with a cancer drug, report scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the... view more (2008-02-14)

Benefit of cancer prevention surgery differs between women with BRCA1 and BRCA2 mutations
The surgical removal of the ovaries has been widely adopted as a cancer-risk-reducing strategy for women with either BRCA1 or BRCA2 mutations.   view more (2008-02-12)

New finding may help explain development of preeclampsia
In a study of pregnant women, those with pregnancy-induced high blood pressure were found to have higher levels of a peptide that raises blood pressure in the pieces of tissue linking mother and fetus, according to researchers at Wake Forest University Baptist Medical Center.   view more (2008-02-11)

NIAID scientists identify new cellular receptor for HIV
A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body's immune system, according to researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of... view more (2008-02-11)

New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls.   view more (2008-02-07)
