Draining away brain's toxic protein to stop Alzheimer's

...le with the disease. Then the team demonstrated an experimental method in mice to fix the process, dramatically reducing the levels of the toxic protein in the brain and halting symptoms. The team is now working on developing a version of the protein that could be tested in people with the disease. The approach...

Shining light on pancreatic cancer

...sed with a simultaneous colonoscopy. Because the experimental procedure only scans the outer few centimeters of the colon and does not require the uncomfortable cleansing process required for a colonoscopy, the researchers believe the approach will encourage more people to get screened before they develop sympt...

Helicopter flight trials for EGNOS

...ls were performed by Eurocopter, using their EC155 experimental all-weather helicopter (Hlicoptre Tous Temps HTT). The trial programme was coordinated by skyguide, the Swiss air navigation service provider and consisted of a number of validating approaches performed by the HTT to a Helicopter Emergency Medical S...

Surgery by satellite -- New possibilities at medicine's cutting edge

...nd robot by the Internet and by satellite. Their experimental surgical trials showed that the delays were much greater when they used the satellite link than using the Internet (600ms vs 55 ms respectively). But after a short period of practice, the surgeon got used to this and there were no measurable differen...

Folic acid supplements do not appear to reduce risk of colorectal tumors

"Nonetheless, by the nature of the design, the results do not provide information on primary prevention by folic acid (the potential for foli...

Research shows survival benefit for leukemia patients treated with arsenic trioxide

The enhanced effectiveness of the experimental combination also resulted in better overall survival after three years among 86 percent of the patients who received the arsenic trioxide regimen, compared to 79 percent for patients on the standard treatment. Up to 30 percent of patients with APL ...

AMPAKINE compounds a new potential treatment for respiratory depression

Greer and coworkers treated rats with the opioids analgesic fentanyl or the barbiturate sedative Phenobarbital, both commonly prescribed in the United States. Greer used a technique kn...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...(AAV). AAVs have already been approved as safe for experimental gene therapy by the U.S. Food and Drug Administration, eliminating a tremendous regulatory hurdle. If successful, this next study will provide the proof of principle needed for the team to apply for phase I human clinical trials, perhaps within 18 mo...

The blood pump is made of titanium and weighs just over half a pound, compared to the 5 pounds of older pumps. The implanted bl...

Retinol lotion reduces the fine wrinkles from natural aging of skin

Many retinol containing cosmeceutical creams, however, are sold by various companies. Those specific products were not tested by the U-M team. The reduction of wrinkles in the studys participant...

Targeted nanoparticles incorporating siRNA offer promise for cancer treatment

...les in preclinical cancer models. By combining the experimental data with a mathematical model of siRNA-mediated gene silencing, we illustrate several practical considerations that we believe will be directly relevant to the clinical application of siRNA-based therapeutics in cancer therapy." ...

It is therefore critical that we understand how age alters the heart, and how older hearts respond to disease." Together with researcher Dr Jason Peart, his team have identifie...

Combination treatment stymies breast cancer growth

Adding two other experimental drugs gefitinib and pertuzumab -- that inhibit HER-2 in different ways can more completely block the growth signals in the tumor, causing it to die. In one of the tumors studied in this report, blocking the stimulatory effects of estrogen on the t...

But when Georgia Tech experimental physicist Elisa Riedo and her team directly measured the force of pure water in a nanometer-sized channel, they found evidence suggesting that water was organized into layers. Riedo conducted these measurements by recording the force placed on a sili...

Penn study on lung-infecting bacterial enzyme suggests new approach to cystic fibrosis treatment

The researchers found that direct exposure of the CFTR-containing oocytes to SMase of Staphylococcus aureus and Bacillus anthracis bacter...

Obesity may be linked to middle ear effusions in children
