Scientists have reported that an experimental vaccine targeting one of the most common genetic drivers of pancreatic cancer, called mutant KRAS, is safe and generated a durable immune responses aimed at preventing the cancer.
A technique from Case Western Reserve University seeks to address two challenges inherent in brain-implantation technology; gaging the property changes that occur during implantation and measuring on a micro-scale.
The authors seek to make some progress down the bioengineering path — crafting a device that can withstand the physiological conditions in the brain for the long-term.
9 ancient Egyptian iron beads which were carefully hammered into thin sheets before being rolled into tubes over 5,000 years ago were actually hammered from pieces of meteorites and not iron ore.
The objects trace their origins to outer space and predate the emergence of iron smelting by two millennia.
The beads were originally strung into a necklace together with other exotic minerals such as gold and gemstones, revealing the high value of this exotic material in ancient times, say the scholars in the Journal of Archaeological Science.
A new paper says that a Chinese herbal medicine called Ji-Sui-Kang (JSK), given systemically for three weeks after injury in rats, improved locomotor function, reduced tissue damage, and preserved the structure of neural cells compared to control rats.
Their data also claim that Ji-Sui-Kang may first act to reduce inflammation and cell apoptosis and death, and boost local oxygen supply while, later on, it appears to restore function and promote tissue regeneration. The researchers did the study because while Chinese herbal medicines have been used for a variety of ailments, the rationale is based more on anecdotal evidence than controlled experiments.
Researchers have unearthed the remains of massive ancient fortifications built around an Iron-Age Assyrian harbor in the contemporary Israeli coastal city of Ashdod, just south of Tel Aviv.
At the heart of the well-preserved fortifications is a mud-brick wall up to more than 12 feet wide and 15 feet high. The wall is covered in layers of mud and sand that stretch for hundreds of feet on either side. When they were built in the eighth century B.C., the fortifications formed a daunting crescent-shaped defense for an inland area covering more than 17 acres.
Racial and ethnic communities in the United States prioritize health concerns differently and addressing those concerns in culturally-specific ways may be beneficial, new results from the University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health show.
A team of researchers suggest that increased coffee intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD).
And here you thought it was just delicious.
Worldwide, 70 percent of people diagnosed with diabetes and obesity have non-alcoholic fatty liver disease, the major cause of fatty liver not due to excessive alcohol consumption. It is estimated that 30 percent of adults in the United States have this condition, and the authors in Singapore say its prevalence is rising there.
There are no effective treatments for
non-alcoholic fatty liver diseas
except diet and exercise.
The people of Youngstown, Ohio say they never felt an earthquake before two-and-a-half years ago. But between January of 2011 and February of 2012, 109 tremors were recorded and the author of a new article points the finger at hydraulic fracturing - fracking.
In December 2010, Northstar 1, a deep injection well built to pump wastewater produced by fracking in the neighboring state of Pennsylvania, came online. In the 14 months that followed seismometers in and around Youngstown recorded 109 earthquakes; the strongest was a magnitude 3.9 earthquake on December 31, 2011. Six of them could be 'felt'.
Researchers studying how oxidative stress in cells impacts sarcopenia, a loss of muscle mass and strength that occurs in all humans as they age, found that mice lacking a protective antioxidant protein did not have reduced size or number of muscles cells but they were weaker than normal ones.
The antioxidant protein is called SOD1 and the researchers developed mice that did not have SOD1 in their muscles, though it was still present in other types of cells. They found that the lack of SOD1 at the muscle was not enough to cause atrophy, the total muscle mass in this mouse was larger, but they were still weak.
There is no 'you are now exiting the solar system' sign at the entrance to interstellar space, so when, and perhaps if, Voyager 1 left the solar system remains a mystery - but a team says it has definitely happened by now.
Voyager 1, carrying with it Earthly greetings on a gold plated phonograph record, still-operational scientific instruments and the future plot of "Star Trek: The Motion Picture", has traveled farther from Earth than any other human-made object.
Two laboratory studies found that the flavonoids apigenin and luteolin, found in celery, artichokes and herbs like Mexican oregano, kills human pancreatic cancer cells in vitro by inhibiting an important enzyme.
Heavy use of magnetic resonance imaging (MRI) may be leading to unnecessary breast removal in older women with breast cancer, according to a new study. The research team tracked the use of breast MRI and surgical care of 72,461 female Medicare beneficiaries age 67-94 who were diagnosed with breast cancer during 2000 to 2009.The team found a considerable increase in the use of preoperative breast MRI over the study period from 1% in 2000-2001 to 25% in 2008-2009. The researchers also found that women who received an MRI were more likely to subsequently undergo more aggressive surgical treatment. In women who received mastectomy, 12.5% of those who had MRI received bilateral mastectomy, while only 4.1% of those who did not have MRI had bilateral mastectomy.
More people are seeking natural alternatives to medicine and products containing probiotics have flooded the marketplace. Probiotics are safe and tolerable but their value remains unknown. Studies are being done with specific illnesses to see if probiotics work and how.A randomized, double-blind, placebo-controlled trial found that the probiotic Saccharomuces boulardii (S. boulardii) does not appear to have any significant beneficial effects for patients with Crohn's disease who are already in remission.
