New research tool replicates extreme environmental conditions to help understand the human body's response to everyday stresses

A new research tool will allow University of Oregon scientists to replicate an extreme range of environmental conditions in their quest to test and understand the human body's response to everyday stresses.

Researchers use PET/CT for molecular imaging of the heart

For the first time, researchers used positron emission tomography (PET)/computed tomography (CT) for imaging the subcellar function of the heart - from its subcellular function to its morphologic appearance. The results of the study were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.

Women who have a special genetic profile can conceive spontaneously after the age of 45 years

Dr. Neri Laufer, from the Hadassah University Hospital, Jerusalem, Israel, told the conference that his team's work to identify a specific gene expression profile linked to later fertility would help understanding of the ageing process, as well as enabling the development of better treatments for infertility in older patients.

Australian researchers at the forefront of an international project to identify genes associated with schizophrenia

University of Queensland researchers are at the forefront of an international project to identify genes associated with schizophrenia, a common mental illness whose causes are not fully understood.

Study shows why thiazolidinediones cause edema and helps understand role of kidneys in hypertension

In related discoveries with far-reaching implications for treating diabetes and understanding hypertension, University of Utah researchers have learned why thiazolidinediones (TZDs), a major anti-diabetes drug, cause edema and also have found a new pathway critical to fluid metabolism. Identification of this pathway may help understand fundamental mechanisms of blood pressure control.

Most common form of lung cancer may begin in a group of newly isolated lung stem cells

Working in a mouse model, the researchers isolated a novel type of lung cell that can divide into fresh copies of itself and into the two more specialized kinds of cells deep in the lung.

Specific genetic linkages to bipolar disorder

Despite an intensive effort, researchers have yet to identify the genes that cause bipolar disorder, yet the practical benefits of such a discovery could reap rich rewards for those suffering from the mental illness.

Researchers explore the genetic roots of congenital diaphragmatic hernias

To breathe normally, people need more than just healthy lungs. A diaphragm - the large muscle that creates a vacuum to draw air into their lungs - is also crucial.

Inactive gene may explain higher incidence of prostate cancer in African-Americans compared to Caucasians

Among African-Americans with prostate cancer, a tumor-suppressing gene called GSTP1 is inactivated at a rate 3.5 times higher than among Caucasians, according to a study conducted at the San Francisco VA Medical Center (SFVAMC).

Scientists have tracked down the biological trigger that gives rise to Van Buchem disease

...a hereditary, disfiguring bone disorder that can cause blindness and deafness. The findings provide insight into long-range gene regulation and could lead to new treatments for osteoporosis and other crippling bone disorders.

High exposure to the sun halves risk of prostate cancer

Cancer researchers in the U.S. say that high exposure to the sun halved the risk of prostate cancer in men participating in a U.S. trial.

Aortic disease difficult to diagnose

Aortic disease kills nearly 15,000 people in the United States each year, but the rarity and complexity of this deadly disorder make accurately diagnosing it difficult for doctors in the health-care trenches, University of Florida researchers have found.

Jumping genes help detemine uniqueness of individual brains

Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells.

New research shows that genes exert powerful effect on sexual behavior

New research has shown that the manipulation of a single gene in female fruit flies can make their sexual behavior resemble that of males, in a study that demonstrates the power of individual genes and the profound impact of genetics on complex sexual behavior.

Report on Hispanics and genes, culture, and medicines highlights the rise of individualized medicine

"The FDA's review today of BiDil could make it the first drug approved specifically for African Americans and marks the end of 'one-size-fits-all' medicine," said Dr. Jane L. Delgado, President and CEO of the National Alliance for Hispanic Health (the Alliance), the nation's leading Hispanic health advocacy group.
