Leesburg, VA, September 13, 2019--Although Medicare claims data confirm the increasing role of nurse practitioners and physician assistants (NPPs) in imaging-guided procedures across the United States, according to an ahead-of-print article published in the November issue of the American Journal of Roentgenology (AJR), NPPs still rarely render diagnostic imaging services, compared with the overall number of diagnostic imaging interpretations.
When NPPs do render diagnostic imaging services, though, said services are overwhelmingly radiography and fluoroscopy.
BIRMINGHAM, Ala. - The body's immune response fights against infectious disease, and it safeguards against future infections through vaccination. However, if the immune response dysfunctions and attacks the body itself, it can cause autoimmune disease. Thus, a healthy immune response balances an instant readiness to combat infecting viruses or bacteria, while maintaining benign surveillance of the body's own tissues.
Men and ethnic minorities are less likely to wear cycle helmets and more likely to suffer from head and neck injuries in accidents, according to new research published in Brain Injury.
The study, looking at over 70,000 US cyclists' injuries from 2002-2012, found only 22% of the adult population (21% of males, 28% of females) and 12% of the younger riders who suffered these types of injuries, used helmets while riding a bicycle.
A cube one-fortieth the size of a human red blood cell can glow when it detects flammable gas. The nanocube, designed by chemists at the University of Tokyo, is part of a research project to develop artificial systems that mimic the complex chain of events inside living cells.
The research team has worked on the nanocube project for over a decade. A key feature of the nanocube, just two nanometers on each side, is that it puts itself together, attempting to mimic the way proteins and DNA put themselves together in living cells.
Mimicking life
Osaka, Japan - Researchers from Osaka University have made the striking discovery that multidrug-resistant bacteria may have been around longer than we thought.
In findings published this month in Communications Biology, the researchers investigated the evolutionary relationships among hundreds of RND-type efflux pumps—specialized proteins that pump multiple different types of antibiotics out of a bacterial cell, making it multidrug resistant.
New research from a group of Vanderbilt biomedical engineers reveals that while cancer cells move quickly in metastasis, they're rather lazy in which paths they choose.
For male Trinidad Guppies applies: if you are hungry, seek female company. A recent study led by scientists of the the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Leibniz Institute for Zoo and Wildlife Research (IZW) together with other research institutions provides evidence that male guppy fish in the presence of females more often ended up at novel food patches. In contrast, female food discovery was independent of male presence.
An international collaboration of scientists in Iceland, Denmark and the Netherlands has for the first time used ancient DNA analyses and C14-dating to demonstrate the past existence of a unique population of Icelandic walrus that went extinct shortly after Norse settlement some 1100 years ago. Walrus hunting and ivory trade was probably the principal cause of extinction, being one of the earliest examples of commercially driven overexploitation of marine resources.
The Large Magellanic Cloud, or LMC, is one of our nearest galactic neighbors, at only 163 000 light years from Earth. With its sibling the Small Magellanic Cloud, these are among the nearest dwarf satellite galaxies to the Milky Way. The LMC is also the home of various stellar conglomerates and is an ideal laboratory for astronomers to study the processes that shape galaxies.
Disabled people face being marginalised by the very programmes that are designed to help them.
Rather than taking their differences and particular preferences into account, projects and welfare systems established to provide support are normalising disabled people, and unintentionally contributing to their further marginalisation.
Astronomers using one of the most advanced radio telescopes have discovered a rare molecule in the dust and gas disc around a young star - and it may provide an answer to one of the conundrums facing astronomers.
The star, named HD 163296, is located 330 light years from Earth and formed over the last six million years.
An innovative solution used to prevent common brain infections in patients having surgery for hydrocephalus has been found to significantly reduce infection rates according to a report published in The Lancet today (12 September 2019).
Hydrocephalus is a build-up of fluid on the brain. The excess fluid puts pressure on the brain, which can damage it. Approximately one out of every 500 babies is born with hydrocephalus, making it the most common reason for brain surgery in children.
New findings released Sept. 12 from a groundbreaking gambling study by a University of Massachusetts Amherst research team show that out-of-state casino gambling among Massachusetts residents decreased significantly after the Commonwealth's first slot parlor, Plainridge Park Casino, opened in Plainville in the summer of 2015.
A phase 2 clinical trial has found that combining a molecular targeted drug called temsirolimus with chemotherapy shows promise in the treatment of rhabdomyosarcoma, the most common soft tissue sarcoma in childhood.
