For more than 30 years, board-certified dermatologists have been providing free skin cancer screenings in their communities through the AAD’s SPOTme® program — and research published today highlights the value of that program.
As adults age, they all experience a natural loss of muscle mass and function. A new study finds that as the loss of muscle and function in the throat occurs it becomes more difficult for efficient constriction to occur while swallowing – which leads to an increased chance of food and liquids being left over in the throat.
Nobody knows exactly what happens at the eye of the storm. But biologists have published a first-of-its-kind look at the physical characteristics of lizards that seem to make the difference between life and death in a hurricane, as reported on July 25 in the journal Nature. Hint: long, strong back legs do not help like you think they might.
Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered an earlier unknown discontinuous magnetoelastic transition in a rare-earth intermetallic. The mechanism of the material’s changing magnetic state is so unusual, it provides new possibilities for discovery of similar materials.
Parkinsonism – slowed movement, muscle rigidity and tremor – is a classic set of neurological symptoms most often seen in patients with Parkinson’s disease. Because neuron loss in the substantia nigra – a region of the brain associated with motor planning – is the hallmark characteristic of Parkinson’s disease, parkinsonism has long been thought to originate there. However, parkinsonism can occur in patients who have other conditions that leave the substantia nigra intact, making the true source of the suite of symptoms a mystery.
Finding could lead to targeted therapies for chronic condition
Patients who undergo coronary artery bypass grafting (CABG)—the most common heart surgery performed—may live longer and experience fewer complications when under the care of a highly focused surgical team that uses simplified and standardized approaches.
In a paper published online this spring in the journal Nature Photonics, scientists at the University of Washington report that a prototype semiconductor thin-film has performed even better than today’s best solar cell materials at emitting light.
Two units of plasma given in a medical helicopter on the way to the hospital could increase the odds of traumatically injured patients with severe bleeding surviving by 10 percent, according to the results of a national clinical trial.
People who feel faint, dizzy or lightheaded when standing up may be experiencing a sudden drop in blood pressure called orthostatic hypotension. Now a new study says middle-aged people who experience such a drop may have a greater risk of developing dementia or stroke decades later. The study is published in the July 25, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Research conducted at the Wayne State University School of Medicine has helped confirm the effectiveness of a blood biomarker that can indicate if patients with a head injury can avoid a costly CT scan because the blood test results indicate no traumatic brain injury (TBI).
How do we define and measure worker well-being? A proposed conceptual framework, with implications for future efforts to improve occupational safety and health, is presented in the July issue of Journal of Occupational and Environmental Medicine.
A cutting-edge laboratory technique that turns human stem cells into brain-like tissue now recapitulates human brain development more accurately than ever, according to a new study from Case Western Reserve University School of Medicine. The study, published in Nature Methods, demonstrates how to grow brain “organoids”—self-organizing mini spheres that now contain all the major cell types found in the human cerebral cortex—in laboratory dishes.
A stream classification system developed by researchers at the Department of Energy’s Oak Ridge National Laboratory can help assess physical changes to United States streams and rivers from human influences and aid in more effective management of water resources.
Research published today in the journal Nature provides new understanding about how drugs can repair damaged brain cells that cause disability in patients with multiple sclerosis. Led by researchers at Case Western Reserve University School of Medicine, the study suggests new drug targets and potent early-stage drug candidates could lead to regenerative medicines for multiple sclerosis and other debilitating neurological diseases.
Immune cells that normally rush in to protect the eyes from infection might actually be disrupting moisturizing glands and causing dry eye, a disease that afflicts more than 30 million people in the United States.
A gene linked to 3 to 4 percent of people with Parkinson’s disease could play an important role in most, if not all, people with the disease, according to a new study. The findings suggest that treatments being developed for this small group of people may benefit many more patients than previously thought.
For decades, Americans' anger at government has been growing, despite the increase in benefits people receive from that same government. Suzanne Mettler explores this growing gulf between people’s perceptions of government and the actual role it plays in their lives in her latest book, “The Government-Citizen Disconnect.”
The results of the first ever clinical trial of focused ultrasound to open the blood-brain barrier (BBB) in patients with Alzheimer’s disease were published today in Nature Communications and also presented at the Alzheimer’s Association International Conference (AAIC) in Chicago, Illinois. The pilot trial demonstrated the feasibility and preliminary safety of focally, reversibly and repetitively opening the BBB.
In a study published online July 25 in the journal Nature, University of California San Diego School of Medicine researchers identified a signaling pathway that activates the NLRP3 inflammasome implicated in several severe chronic inflammatory disorders.
