Data showed that AME-133v had a potent tumor-halting response in patients with follicular lymphoma, a portion of lymphoma cases. Results add to research showing a new class of monoclonal antibodies like AME-133v may lengthen survival times, according to researchers at the University of Alabama at Birmingham.
The scientists were investigating the lifestyle of two early elephants (proboscideans) Moeritherium and Barytherium that lived in the Eocene period, over 37 million years ago. By analysing isotopes in tooth enamel from Moeritherium they were able to deduce that it was very likely a semi-aquatic mammal, spending its days in water eating freshwater plants.'
Typing on a keyboard or scribbling on paper may be similar activities, but there is a significant difference in how the body moves, according to new motor development research. In a physical therapy setting many skills are taught discretely first, such as stepping or bending a joint, and then the patient is told to perform continuously, such as walking. Humanoid robots, which resemble people and walk upright, often control movements as a series of discrete actions.
Songbirds feeding near the contaminated South River are showing high levels of mercury, even though they aren't eating food from the river itself, according to a new article in Science. Mercury is one of the world's most troublesome pollutants, especially in water. "The birds eat a lot of spiders... The spiders have a lot of mercury in them and are delivering the mercury to these songbirds," one of the researchers said.
Interventional cardiologists now offer a minimally-invasive transcatheter valve replacement procedure for patients with congenital heart disease that doesn't involve open heart surgery. Recently, the minimally-invasive pulmonic valves were successfully implanted the first three patients.
People with low vitamin D levels may face an increased risk for peripheral artery disease, according to scientists. PAD is a common disease that occurs when arteries in the legs become narrowed by fatty deposits, causing pain and numbness and impairing the ability to walk.
Compared to older drugs for Parkinson disease, a newer class of medications called dopamine agonists might be better at preventing some of the disabling muscle control problems associated with the disease and its treatment, a new review concludes. However, patients who take the new drugs suffer from an increase in numerous side effects, and are more likely to drop out of treatment.
Computer scientists have created a fog and smoke machine for computer graphics that cuts the computational cost of making realistic smoky and foggy 3-D images, such as beams of light from a lighthouse piercing thick fog. By cutting the computing costs, the computer scientists are helping to pull cutting edge graphics techniques out of research labs and into movies and eventually video games and beyond.
Scientists have discovered that tiny filaments on bacteria can bundle together and pull with forces far stronger than experts had previously thought possible. Retraction forces from a bundle allow the bacterium to move objects 100,000 times its body weight.
Pregnancy rates could be doubled for couples undertaking certain fertility treatments, thanks to a revolutionary project currently being trialled. Researchers have devised a new formula to significantly improve embryo implantation rates and reduce pregnancy complications in assisted reproductive technology (ART).
