A close examination of federal survey data shows that while many settings including ERs cut back on prescribing opioids for more than a decade, physicians' offices continued to prescribe them.
Two independent teams of scientists from the University of Utah and the University of Massachusetts Medical School have discovered that a gene crucial for learning, called Arc, can send its genetic material from one neuron to another by employing a strategy commonly used by viruses. The studies, both published in Cell, unveil a new way that nervous system cells interact.
Amoebae, single-celled organisms common in soil, water and grade-school science classrooms, may play a key role in the survival and spread of deadly plague bacteria. New Colorado State University research shows that plague bacteria, Yersinia pestis, not only survive, but thrive and replicate once ingested by an amoeba. The discovery could help scientists understand why plague outbreaks can smolder, stay dormant for years, and re-emerge with a vengeance.
A research team that includes Children's National Health System clinician-researchers has validated a way to outfox tumors. They engineered T-cells, essential players in the body's own immune system, to strip tumors of their self-preservation skill and were able to hold Hodgkin lymphoma at bay in patients with relapsed disease for more than four years.
For anyone who has accidentally injured themselves, Dr. Zachary Campbell not only sympathizes, he's developing new ways to blunt pain. Campbell, who researches pain on the molecular level at the University of Texas at Dallas, recently published a study in the journal Nature Communications that describes a new method of reducing pain-associated behaviors with RNA-based medicine, creating a new class of decoy molecules that prevent the onset of pain.
Cleveland Clinic researchers have confirmed for the first time a mechanistic link between the gene HSD17B4 and deadly, treatment-resistant prostate cancer. The research, led by Nima Sharifi, M.D., Cleveland Clinic Lerner Research Institute, Department of Cancer Biology, shows that men who lack a certain subtype of the gene may be more susceptible to aggressive prostate cancer that does not respond to treatment.
A new study describes novel probes that enable non-invasive, non-destructive, direct monitoring of the differentiation of mesenchymal stem cells (MSCs) in real-time during the formation of engineered cartilage to replace damaged or diseased tissue.
A new, first-of-its-kind study was published in the Journal of the American Geriatrics Society by scientists from research centers in Montreal and Quebec City, Canada. They designed a study to learn whether cognitive training, a medication-free treatment, could improve MCI. Studies show that activities that stimulate your brain, such as cognitive training, can protect against a decline in your mental abilities. Even older adults who have MCI can still learn and use new mental skills.
A new study from the University of Washington Institute for Learning & Brain Sciences provides one of the first looks inside the infant's brain to show where the sense of touch is processed -- not just when a baby feels a touch to the hand or foot, but when the baby sees an adult's hand or foot being touched, as well. Researchers say these connections help lay the groundwork for the developmental and cognitive skills of imitation and empathy.
More than 10,000 people in the United States are living with memory loss and other persistent neurological problems that occur after West Nile virus infects the brain. Now, a new study in mice suggests that such ongoing neurological deficits may be due to unresolved inflammation that hinders the brain's ability to repair damaged neurons and grow new ones. When the inflammation was reduced by treatment with an arthritis drug, the animals' ability to learn and remember remained sharp after West Nile disease.
