Damage to the brain's outer layer caused by smoking may be reversible after quitting, but it could take years, a study said. Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported.
Silibinin has an outstanding safety profile in humans and is currently used for the treatment of liver disease and poisoning.
University of Chicago Medicine researchers have built a model system that uses multiple cell types from patients to rapidly test compounds that could block the early steps in ovarian cancer metastasis. Their three-dimensional cell-culture system, adapted for high-throughput screening, has enabled them to identify small molecules that can inhibit adhesion and invasion, preventing ovarian cancers from spreading to nearby tissues.
Scientists at The Scripps Research Institute (TSRI) have identified a new cellular pathway that is affected in cystinosis, a rare genetic disorder that can result in eye and kidney damage.
The researchers, from Cancer Research UK's Health Behaviour Research Centre at University College London (UCL), interviewed almost 1,900 people aged 50-80 years old about their views on cancer screening.
Firsthand experience working in hospitals and clinics helped inspire third-year Stanford medical student Pelu Tran to explore a potential career path in the world of high-tech startups.
Mice genetically deficient in serotonin -- a crucial brain chemical implicated in clinical depression -- are more vulnerable than their normal littermates to social stressors.
Ebola has claimed nearly 9,000 lives in West Africa over the past year, although new infections have dropped dramatically in recent months.
Researchers have revealed how damage from obesity is passed from a mother to her children, and also how that damage can be reversed.
After the highly charged Super Bowl, two sobering studies emerged. One unveiled an improved molecular imaging technology that verified—and precisely identified—brain damage in some National Football League (NFL) players. The other study revealed that brain damage can be more severe in NFL players who start playing football before age 12.
MicroRNA are the tiny non-coding RNA molecules that help determine whether genes are expressed or silenced.
Researchers have revealed new insights into possible ways to vaccinate people to generate potent antibodies of the type that are predicted to offer protection against diverse strains of the highly mutable HIV.
Several state legislatures are debating vaccine-related measures as dozens of people have fallen ill from a measles outbreak that started at Disneyland in December and spread beyond the theme park.
A new Dartmouth College study sheds light on the brain cells that function in establishing one's location and direction. The findings contribute to our understanding of the neural mechanisms underlying our abilities to successfully navigate our environment, which may be crucial to dealing with brain damage due to trauma or a stroke and the onset of diseases such as Alzheimer's.
Have you ever wondered why it’s so tough to put down that last slice of bacon? Part of the answer is that humans are evolutionarily programmed to crave fatty foods, which offer the biggest bang for the buck, nutritionally speaking, with more than twice the calorie density of protein- or starch-rich food.
SuperAgers, aged 80 and above, have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research that is beginning to reveal why the memories of these cognitively elite elders don’t suffer the usual ravages of time.
In the 1980s, immunotherapy researcher Lieping Chen, M.D., Ph.D., embraced the career goal of curing one cancer. That lofty-seeming goal is beginning to look more modest today. Recent clinical trials have shown that one cancer after another is vulnerable to immune modulation therapy, a cancer-fighting strategy Chen pioneered that for years was considered marginal.
In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
Since December, more than 100 people in 14 states have been infected with measles in an outbreak traced to Disneyland, Melissa Stockwell, MD, MPH, assistant professor of pediatrics and of population & family health, has spoken out to debunk seven myths about the measles vaccine.
The largest U.S. measles outbreak in recent history isn't the one that started in December at Disneyland. It happened months earlier in Ohio's Amish country, where 383 people fell ill after unvaccinated Amish missionaries traveled to the Philippines and returned with the virus.
Researchers said they can tell who will become depressed or anxious in response to stressful life events, as far as four years down the road.
Scientists have found diverse genomic changes in single neurons from the brains of Alzheimer’s patients, pointing to an unexpected factor that may underpin the most common form of the disease.
The drop-off in Ebola infections is good news for Liberia, but it means there are not enough sick people to take part in the study.
Federal health officials faced tough questions from lawmakers Tuesday about why they didn't take steps to produce a better flu vaccine as it became clear that this year's version wasn't going to offer much protection.
