When a patient is diagnosed with rheumatoid arthritis, psoriatic arthritis or spondyloarthritis, prescribing the correct type of medicine is a case of trial and error. It is simply not possible to predict which medication will work for the individual patient, and it is therefore a matter of trying the different treatment options: glucocorticoids, low dose chemotherapeutic drugs or newer biological drugs. Until now!
ANN ARBOR--Conventional thinking is that bone regeneration is left to a small number of mighty cells called skeletal stem cells, which reside within larger groups of bone marrow stromal cells.
But new findings from the University of Michigan recasts that thinking.
In a recent study, Noriaki Ono, assistant professor at the U-M School of Dentistry, and colleagues report that mature bone marrow stromal cells metamorphosed to perform in ways similar to their bone-healing stem cell cousins--but only after an injury.
CHAMPAIGN, Ill. -- Before they can get started at their field site - a giant cave studded with stalactites, stalagmites and human artifacts - 15 undergraduate students must figure out how to use their virtual hands and tools. They also must learn to teleport.
Writing in the journal Stem Cells Translational Medicine, an international research team, led by physician-scientists at University of California San Diego School of Medicine, describe a new method for delivering neural precursor cells (NSCs) to spinal cord injuries in rats, reducing the risk of further injury and boosting the propagation of potentially reparative cells.
The findings are published in the Jan. 29, 2020 print issue.
Autism is characterized in part by an individual's challenges communicating and interacting socially with others. These difficulties have typically been studied in isolation by focusing on cognitive and behavioral differences in those with autism spectrum disorder, but little work has been done on how exchanges for autistic people unfold in the real world.
DURHAM, N.C. -- Biomedical engineers at Duke University have demonstrated that at least 25 percent of antibiotic-resistant pathogenic bacteria found in clinical settings are capable of spreading their resistance directly to other bacteria. At the same time, the study shows that, despite common beliefs, the use of antibiotics does not significantly affect the rate at which the genes responsible for resistance are swapped between bacteria.
MADISON, Wis. -- University of Wisconsin-Madison researchers have developed nanoparticles that, in the lab, can activate immune responses to cancer cells. If they are shown to work as well in the body as they do in the lab, the nanoparticles might provide an effective and more affordable way to fight cancer.
They are cheaper to produce and easier to engineer than the antibodies that underlie current immunotherapies, which as drugs cost tens of thousands of dollars a month.
What makes people more or less mindful from one situation to the next? Researchers have found that mindfulness is not entirely something an individual brings to a situation and rather is partly shaped by the situations they encounter.
The brain undergoes dramatic change during the first years of life. Its circuits readily rewire as an infant and then child encounters new sights and sounds, taking in the world and learning to understand it. As the child matures and key developmental periods pass, the brain becomes less malleable--but certain experiences create opportunities for parts of the adult brain to rewire and learn again.
DALLAS - Jan. 29, 2020 - In a new report published today in Circulation, experts outline national and global goals to help people live healthier for longer. While heart disease and stroke-related deaths continue to decline, the rate at which they're declining has slowed and obesity rates are on the rise.
2019-nCoV likely emerged very recently and was detected relatively rapidly.
The virus may use the same molecular 'doorway' as severe acute respiratory syndrome (SARS) to enter human cells.
A new genetic analysis of 10 genome sequences of novel coronavirus (2019-nCoV) from nine patients in Wuhan finds that the virus is most closely related to two bat-derived SARS-like coronaviruses, according to a study published in The Lancet.
Highly active adults engage in a greater variety of physical activities than do less active adults, finds a new study led by researchers at NYU Rory Meyers College of Nursing.
The study, published in the journal Translational Behavioral Medicine, also revealed that walking is the most common type of exercise, followed by cycling and dancing.
Members of disadvantaged social groups who engage in contact with members of privileged groups are less likely to support social change toward equality, a multinational study by social psychologists at the University of Zurich shows. To reduce this effect, it is important to actively address and acknowledge inequalities in intergroup contacts.
A Dartmouth-led study finds that two common economic interventions in Afghanistan designed to improve economic livelihoods and win the "hearts of minds" of civilians was ineffective in reducing support for the Taliban in the long run.
