Biologists decipher novel functions of metal-binding molecule nicotianamine

In order to survive, plants should take up neither too many nor too few minerals from the soil. New insights into how they operate this critical balance have now been published by biologists at the Ruhr-Universit-t in a series of three papers in the journal The Plant Cell. The researchers discovered novel functions of the metal-binding molecule nicotianamine.

Without scale-up of aid, Africa's Sahel region facing humanitarian crisis, U.N. warns

"Senior United Nations officials on Tuesday made impassioned appeals to the international community to make more resources available to assist millions of people affected by the severe food and nutrition crisis in the Sahel region of West Africa, cautioning that global inaction could lead to a humanitarian disaster," the U.N. News Centre reports.

Reducing iron levels in blood plasma may protect brain from changes related to AD

Alzheimer's disease (AD) is now the sixth leading cause of death among Americans, affecting nearly 1 in 8 people over the age of 65. There is currently no treatment that alters the course of this disease. However, an increasing amount of evidence suggests that changes in the way the body handles iron and other metals like copper and zinc may start years before the onset of AD symptoms. A new study shows that reducing iron levels in blood plasma may protect the brain from changes related to AD.

Heart cells starved of nutrients less likely to be damaged during ischemia, reperfusion

Heart cells starved of nutrients are less likely to be damaged during periods of decreased blood flow and sudden influxes of blood, known as ischemia and reperfusion, and are also less likely to get out of synch with their cellular neighbors, the damaging phenomenon called arrhythmia.

Medicaid news: Oregon competitors working together; Calif. 'duals' project launches

A new push to reshape health care in greater Portland is reminiscent, its biggest booster says, of the race to land a man on the moon. Erstwhile health care competitors hope to set aside their differences to care for the region's 200,000 Oregon Health Plan members, says Legacy Health CEO George Brown. The task is happening in a timeline -- Brown snaps his fingers -- "that's like that long. It's a moon shot for sure. What we're trying to do, to my knowledge, has not been attempted any place in the country."

No cancer risk with metal on metal hip replacements: Study

Cancer risk was just one of the fears linked to the implants. Regulators have already called for them to be monitored closely following reports of high failure rates. Tiny metal ions made up of cobalt and chromium are thought to break off from the implants and leak into the blood, with fears that this leads to muscle and bone damage, and neurological issues.

Detailed information on how metastasin protein facilitates spread of tumour cells

Researchers from the Department of Chemistry and Molecular Biology at the University of Gothenburg have managed for the first time to obtain detailed information about the role of the protein metastasin in the spread of tumour cells.

Stimulating specific neurons may reverse age-related memory defects

Scientists from the Florida campus of The Scripps Research Institute have shown in animal models that the loss of memory that comes with aging is not necessarily a permanent thing.

RNA binding motif protein 20 regulates titin splicing

Cardiomyopathy comprises a deterioration of the heart muscle that affects the organ's ability to efficiently pump blood through the body. Previously researchers have tied forms of the disease to the alternative splicing of titin, a giant protein that determines the structure and biomechanical properties of the heart, but the molecular mechanism remained unknown.

Genetic variations could be linked with meconium ileus in CF patients

University of North Carolina at Chapel Hill researchers working as part of the International Cystic Fibrosis Consortium have discovered several regions of the genome that may predispose cystic fibrosis (CF) patients to develop an intestinal blockage while still in the uterus.

FDA seeks expert advice on risks and benefits of MoM hip systems

The U.S. Food and Drug Administration today announced that it is seeking expert scientific and clinical advice on the risks and benefits of metal-on-metal (MoM) hip systems as well as potential patient and practitioner recommendations on the use of MoM hip systems and the management of patients implanted with such devices. FDA will discuss these issues at a two-day expert advisory panel meeting on June 27-28, 2012.
