A motion sensor developed at the Fraunhofer Institutes for Applied Polymer Research in Potsdam and by Computer Architecture and Software Technology in Berlin can enable window panes and glass doors to detect movements because of a special polymer coating.

“The glass is coated with a fluorescent material,” said IAP group manager Burkhard Elling. “The coating contains nanoparticles that convert light into fluorescent radiation.”

He said an ultraviolet lamp “illuminates” the window panes and generates fluorescent radiation in the coating that is channeled to the edges of the window, where it is detected by sensors. If someone steps into the light, less light reaches the coating and less fluorescent radiation is produced. If several sensors are installed on all four sides of the window frame, conclusions can be drawn from the data as to how fast and in what direction an object is moving.

Elling said size can also be estimated by the sensors. Is it a small creature such as a bird or is it a person? The threshold for the alarm can be set, so that moving objects the size of birds, for example, do not trigger an alarm.

HOUSTON (UPI) — The crew of the shuttle Discovery Friday installed solar wings that can double the electricity power available on the International Space Station, NASA said.

When extended, the array measures 240 feet tip to tip and adds 9,600 square feet to the station’s solar arrays, the U.S. space agency said.

The installation was delayed after a small “ripple” in one of the arrays was discovered, but Mission Control in Houston said it wasn’t an issue and that it flattened out naturally when the array was extended.

NEW YORK (UPI) — U.S. scientists say they’ve identified criteria that, when combined with kidney function measures, could create a risk score system for heart-kidney transplant patients.

Dr. Mark Russo of Columbia University Medical Centre/New York-Presbyterian Hospital, who led the study, said such a risk score could help identify patients who are likely to receive a survival benefit from a combined heart and kidney transplant.

“In the past, patients with end-stage heart failure having concurrent renal disease were not considered candidates for heart transplantation,” the researchers said. “With advances in operative techniques and post operative management, combined heart and kidney transplantation is offered to select patients in this population.”

The researchers analyzed data from the United Network for Organ Sharing involving 19,373 patients who underwent heart transplantation between 1995 and 2005. That included 274 patients who received combined heart and kidney transplants and 19,109 who received heart transplants alone.

They said they found patients appeared less likely to survive following a combined heart and kidney transplant if, before surgery, they had peripheral vascular disease, were over 65, had heart failure that wasn’t caused by blocked or narrowed arteries, were dependent on dialysis or were placed on a ventricular assistance device as a bridge to transplantation.

The study appears in the journal Archives of Surgery.

Canine muscular dystrophy therapy created

CANINE MUSCLE TREATMENT

CANINE MUSCLE TREATMENT

ROCKVILLE, Md. (UPI) — U.S. government scientists say they’ve developed a successful treatment for dogs suffering from canine muscular dystrophy, paving the way for human testing.

The National Institutes of Health researchers said the technology, known as “exon skipping,” covers up genetic errors by using tailor-made snippets of DNA-like molecules as molecular “patches.”

The scientists said the patches cover up mutant DNA sequences that have a code algarythm for making an important muscle protein. The mutant sequences occur in portions of the gene known as exons, which contain the information needed to make the muscle protein. By covering up the mutant regions, the DNA patches allow the dogs to make an imperfect but functional, version of the protein and significantly improve their muscle functioning.

Researchers also showed the DNA patches could be delivered by injection throughout the entire body in a much larger animal than a mouse, raising the possibility that they might be successfully delivered throughout the body to human muscles as well.

Lasers may spread Internet to rural areas

LASER BRINGS INTERNET

LASER BRINGS INTERNET

MELBOURNE (UPI) — Australian researchers say they are experimenting with lasers as a way to boost the reach of existing high-speed Internet service to make it accessable to large rural areas.

Ka Lun Lee and colleagues at the University of Melbourne say high-speed digital subscriber line or cable Internet service is too expensive to use in rural areas, since they require extensive networks of equipment and lines. Other technologies, such as satellite and fixed wireless, offer wider coverage but are often unreliable and expensive.

The researchers found gigabit passive optical networks provide the lowest cost at higher bitrates. But Lee said the reach of that technology into rural areas is limited by the loss in signal strength along the optical fibre, with each line only capable of radiating approximately 19 miles from a central office.

To boost that reach, Lee and his team use a device called a ‘Raman amplifier’. Installed in the central office of a network provider, the high-powered laser feeds the optical signals that carry information as it heads out over a fibre. That, said Lee, increases the power and reach of the signal by a factor of nearly 10 times.

NEW YORK (UPI) — U.S. researchers say they’re working on ways to duplicate  the success of laser eye surgery and hair removal into a workable treatment for the ever common toenail fungus.

An estimated 23 million people in the United States have onychomycosis, a fungal condition that discolors and thickens toenails. Current treatments, which include anti-fungal oral concoctions and topical applications, have relatively low success rates, The New York Times reported recently.

There has been some support with treatments using ‘Potassium Permanganate’ [Condy’s Crystals], Salicylic -Benzoic Acid, Tea-tree oil etc.

However Nomir Medical Technologies in Massachusetts said it has now had success in early testing of a laser, called Noveon, which targets bacterial and fungal infections while preserving healthy tissue.
Preliminary analysis shows 76 percent of patients showed evidence of improvement after the Noveon treatment. A significant drop in fungus levels was seen in 74 percent of patients after two treatments.

The findings were presented  at the Council for Nail Disorders 13th Annual Scientific Meeting in San Francisco.

Noveon lasers are currently used for cataract surgery, dental work and hair removal, the newspaper said.

Bypass better than angioplasty at times

Bypass or Angioplasty

PALO ALTO, Calif. (UPI) — The results of several clinical trials around the world has suggested heart bypass surgery is better for some patients than angioplasty, a U.S. study said.

Stanford University School of Medicine said data from about 8,000 research subjects show coronary angioplasty may be the better choice for patients with multi-vessel coronary artery disease who have diabetes or who’s ages are over 65.

Angioplasty, however, may be the best choice for patients under age 55.

“Whether you have diabetes really makes a big difference,” lead author Dr. Mark Hlatky of Stanford said in a statement. “Over several years there’s a much lower rate of death with bypass surgery. The patient’s age and fitness were other major factors that affected outcomes, and this was an interesting surprise.”

For patients with diabetes, the five-year mortality rate was 12 percent for those who had bypass surgery compared with 20 percent for those who underwent an angioplasty. For patients older than 65, the mortality rate was 11 percent for those who had bypass compared with 15 percent for those who had angioplasty.

The findings are published online in The Lancet.

Vaccine to prevent colon cancer tested

Vaccine Development

Vaccine Development

PITTSBURGH (UPI) — U.S. researchers are testing a vaccine to prevent colon cancer in people already at high risk for the disease.

Unlike other anti-cancer vaccines that block viruses, the vaccine has been directed against a variant of a cell protein — called MUC1.

Colon cancer generally starts with an abnormal growth in the intestinal lining — a polyp. When polyps  become cancerous they are called adenomas. Adenomas produce MUC1 in excess.

“When stimulating an immune response against the MUC1 protein in these precancerous growths,one should be able to draw the immune system’s fire to attack and destroy the abnormal cells,” principal investigator Dr. Robert Schoen of the University of Pittsburgh School of Medicine said in a statement. “That might not only prevent progression to cancer, but even polyp recurrence.”

Several people have received the experimental vaccine so far, and the researchers intend to enroll another 50 participants ages 39 to 70 with a history of adenomas sized 1centimeter or more.

After an initial dose of vaccine, the study participants get doses two and 10 weeks later. Blood samples taken then as well — also at 12 weeks, 28 weeks and one year later — will determine and measure immune response.
