Blood pressure-lowering DASH diet also reduces homocysteine

The DASH diet, known for its blood pressure-lowering effects, also reduces homocysteine levels, a risk factor for heart disease. Participants on the DASH diet had lower homocysteine levels compared to those on a control diet or one rich in fruits and vegetables.

Study launched to test public access defibrillation

A large multi-center study is testing the life-saving potential and cost effectiveness of public access defibrillation (PAD). PAD involves placing defibrillators in community locations, where trained volunteers can access them, to improve emergency treatment for sudden cardiac arrest victims.

Jefferson scientists hope to perfect gene therapy without viruses

Researchers at Thomas Jefferson University have developed a new gene therapy system that uses DNA and bacterial proteins to deliver genes to specific places in human DNA, avoiding viruses and their associated immune reactions. The technique shows promise for treating genetic diseases such as hemophilia and sickle cell anemia.

Repairing brain damage from stroke may be possible with brain cell transplants

Researchers have successfully transplanted laboratory-grown neuronal cells into the brains of stroke patients, showing promise for recovering lost abilities. Six months after transplantation, six patients showed significant improvements in motor skills and metabolism, suggesting integration with existing tissue.

Adhesive tricks to recycle old computers

Researchers at Cornell University have developed an environmentally friendly adhesive that can be easily removed and cleaned up, making it possible to recycle outmoded computers. The adhesive, dubbed Alpha-Terp, can be broken down using heat or industrial solvents, allowing for the reuse of valuable components.

Autism screening for all children recommended by guidelines

The American Academy of Neurology recommends routine developmental screening for all children from infancy through school age, focusing on early detection of autism. The guidelines also emphasize the importance of genetic or metabolic testing to rule out conditions that may be confused with autism.

Balanced diet lowers homocysteine, reducing risk of heart disease

A well-balanced diet, such as the DASH diet, significantly lowers blood levels of homocysteine, a by-product of protein metabolism. This reduction is predicted to lower the risk of heart disease by 7 to 9 percent. Additionally, reductions in blood pressure and cholesterol from the DASH diet should further reduce heart disease risk.

New treatment makes fruit juices safer

Researchers at the University of Florida have developed a new treatment method using carbon dioxide to eliminate bacteria from fresh fruit juice, preserving its flavor and appearance. The process is as effective as heat pasteurization in reducing pathogens, but without the undesirable taste change.

One year later: Chandra 'changes way we look at the universe'

Chandra has revealed unprecedented images of a blast wave from an exploding star, a flare from a brown dwarf, and a small galaxy being cannibalized by a larger one. The observatory's high resolution has enabled scientists to pinpoint sources of the X-ray background glow, leading to a better understanding of our universe.

New crop protection method could save US farmers billions

Researchers have discovered that naturally occurring microorganisms can reduce the severity of scab disease, a fungal disease costing US farmers over $3 billion annually. The approach, known as microbial spray, increases naturally occurring bacteria in crops close to harvesting time, reducing the need for chemical fungicides.
