Multiple Sclerosis Disease Progression Clarified Through MRI
Using magnetic resonance images of the brain, researchers have identified a new abnormality related to disease progression and disability in patients with multiple sclerosis, according to a new study. There are four classifications of MS, but the two most common types are relapsing-remitting and secondary-progressive. Patients with relapsing-remitting MS will experience symptom flare-ups followed by periods of no disease progression. Patients with secondary- progressive MS exhibit an initial period of relapsing-remitting MS, followed by steady disease progression. Compound Might Defeat African Sleeping Sickness
One of the most devastating diseases in sub-Saharan Africa almost disappeared in the late 1950s. That disease, African sleeping sickness, or trypanosomiasis, largely succumbed to heroic public health efforts -- including relocating entire villages. But in the past several decades, because of post-colonial turmoil, the catastrophic illness has come back to ravage parts of Angola, the Democratic Republic of the Congo, the Sudan and other countries. In some regions, the tsetse fly-borne infection rivals or exceeds the toll AIDS takes. Obese Heart Attack Patients Are More Likely To Survive After Treatment
Obese and very obese patients have a lower risk of dying after they have been treated for heart attacks than do normal weight patients, according to new research. Researchers found that amongst patients who had received initial treatment for a specific type of heart attack, those that were obese or very obese were less than half as likely to die during the following three years as patients who had a normal body mass index. The Biggest Loser: Weight Loss May Depend On Where Calories Come From
In a small study publishedin the December 2005 issue of the medical journal Diabetes Care,researchers at the Jean Mayer USDA Human Nutrition Research Center onAging at Tufts University discovered that a diet's overall "glycemicload"may be an important determinant of weight loss, but only for somepeople. Culmination of Fulmination
German chemists recently determined the crystal structure of a compound the alchemists knew as “Knallquecksilber”, but which goes by the formal name of mercury(II) fulminate. The compound is highly explosive, sensitive to heat and shock and its control in the form of a detonator material for dynamite gave Alfred Nobel his big break.The new crystal [...] Understanding ocean climate
High-resolution computer simulations are helping to describe the inflow of North Atlantic water to the Arctic Ocean and how this influences ocean climate. A Vaccine Approach To Treating Parkinson's Disease
Researchers at the UCSD School of Medicine working with scientists at Elan Pharmaceuticals, have reported promising results in mice of a vaccine approach to treating Parkinson's and similar diseases. These results appear in the June edition of the journal Neuron. Ninety Percent Of U.S. Wounded Survive: In Iraq, Firepower Increases,
Better, faster medical care has reduced deaths from the more than 10,000 war injuries in Iraq and Afghanistan to the lowest percentage of any war in American history. In World War II, 30 percent of U.S. soldiers died from wounds received in combat; in Vietnam, 24 percent of the wounded died. In Iraq and Afghanistan, despite the horrific increase in the destructibility of weapons, mortality has dropped to 10 percent. Severe Injuries On The Rise Among Children And Adolescents Riding Moto
The use of motorbikes among children and adolescents is dangerous, on the rise and leading to a greater number of injuries, according to a new Cincinnati Children's Hospital Medical Center study. Methane Bubbling Through Seafloor Creates Undersea Hills
According to a recent paper published by MBARI geologists and their colleagues, methane gas bubbling through seafloor sediments has created hundreds of low hills on the floor of the Arctic Ocean. These enigmatic features, which can grow up to 40 meters (130 feet) tall and several hundred meters across, have puzzled scientists ever since they were first discovered in the 1940s.
