Researchers discover HVEM’s unknown role in fighting off E. coli infections

Despite ongoing public health efforts, E. coli outbreaks continue to infiltrate the food supply, annually causing significant sickness and death throughout the world. But the research community is gaining ground. In a major finding, published today in the scientific journal Nature, researchers from the La Jolla Institute for Allergy & Immunology have discovered a molecule's previously unknown role in fighting off E. coli and other bacterial infections, a discovery that could lead to new ways to protect people from these dangerous microorganisms.

IDH mutation drives aggressive form of acute myeloid leukemia

Many patients with acute myeloid leukemia (AML) share a mutation in a gene called IDH. A University of Colorado Cancer Center study published this week in the journal Leukemia & Lymphoma shows that this IDH mutation may be the first domino in a chain that leads to a more aggressive form of the disease.

Scientists uncover new strategy that may help reverse mucus dehydration in CF, COPD

University of North Carolina scientists have uncovered a new strategy that may one day help people with cystic fibrosis and chronic obstructive pulmonary disorder better clear the thick and sticky mucus that clogs their lungs and leads to life-threatening infections.

Researchers link newly discovered gene mutations to ALS

Researchers have linked newly discovered gene mutations to some cases of the progressive fatal neurological disease amyotrophic lateral sclerosis - ALS, also known as Lou Gehrig's disease. Shedding light on how ALS destroys the cells and leads to paralysis, the researchers found that mutations in this gene affect the structure and growth of nerve cells.

Cleveland Clinic receives NHLBI grant to identify new pathways linked with cardiovascular diseases

The National Heart, Lung, and Blood Institute (NHLBI) has awarded a $4.78 million grant to researchers at Cleveland Clinic's Lerner Research Institute to use metabolomics - a new approach that focuses on the small-molecule byproducts of metabolism - for discovery of novel pathways linked to the development of cardiovascular diseases.

Scientists clone tannin gene in sorghum

They might be called a blessing or a curse -- tannins, which are present in certain sorghums, contain health-promoting antioxidant properties, but also provide a bitter taste and decreased protein digestibility. To better understand tannins, their role in sorghum and how they can be altered to improve sorghum's use as food and feed, a team of scientists led by Kansas State University and U.S. Department of Agriculture researchers, has cloned the tannin gene in sorghum.

Body rids itself of excess copper through urine: New study

Scientists have long known that the body rids itself of excess copper and various other minerals by collecting them in the liver and excreting them through the liver's bile. However, a new study led by Johns Hopkins researchers and published June 22 in PLoS One suggests that when this route is impaired there's another exit route just for copper: A molecule sequesters only that mineral and routes it from the body through urine.

Health risks of egg donation for young females

News is just breaking in India about Sushma Pandey, a 17-year-old young woman who died in 2010, two days after her third "egg donation." Her death is being attributed to the procedures used to extract eggs from healthy, desirable young females like Ms. Pandey. These eggs are often resold to affluent westerners for use in commercial production of their children. Her post-mortem report states she had "one abrasion, four contusions and a blood clot in the head, plus six injection marks" as well as "congestion in the ovaries and uterus."

Ajuba protein plays a central role in regulating function of heart stem cells

It is not unusual for babies to be born with congenital heart defects. This is because the development of the heart in the embryo is a process which is not only extremely complex, but also error-prone. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim have now identified a key molecule that plays a central role in regulating the function of stem cells in the heart.

Obesity-fighting tissue in humans is actually not quite brown, says study

The calorie-burning and heat-generating brown fat found in full-grown humans is actually not quite brown; it's beige. So says a new study reported on July 12th in the journal Cell, a Cell Press publication, in which researchers fully characterize this promising obesity-fighting tissue in both mice and humans for the first time.
