The European Bifurcation Club Left Main (EBC MAIN) trial addressed the issue of provisional single stent versus upfront double stenting in 467 patients with true bifurcation distal left main disease.
So far, only one other randomized trial, DKCRUSH-V (n=482), has addressed the same research question, showing better outcomes with an upfront two-stent strategy, more specifically the double-kissing crush (DK CRUSH) technique.
Scientists at the University of Colorado Boulder have tapped into a poltergeist-like property of electrons to design devices that can capture excess heat from their environment--and turn it into usable electricity.
Pollinators in the tropics are less likely to thrive in intensive croplands, finds a new study led by UCL researchers suggesting bees and butterflies are at risk of major losses.
Across the globe, lower levels of land use intensity are good for pollinators, finds the new Nature Communications paper which shows the importance of sustainable land management in cities and agricultural regions.
We are truly never alone, not even within our own bodies. Human beings play host to trillions of bacteria, fungi, viruses, and other microorganisms that make up the human microbiome. In recent years, the mix of these resident bacteria, and the presence of specific bacterial species, has been linked to conditions ranging from obesity to multiple sclerosis.
Irvine, Calif., May 17, 2021 -- Greenhouse gases and aerosol pollution emitted by human activities are responsible for increases in the frequency, intensity and duration of droughts around the world, according to researchers at the University of California, Irvine.
In a study published recently in Nature Communications, scientists in UCI's Department of Civil & Environmental Engineering showed that over the past century, the likelihood of stronger and more long-lasting dry spells grew in the Americas, the Mediterranean, western and southern Africa and eastern Asia.
A team of Welsh academics has developed a new method of supporting health professionals to make clinical decisions about people who may be at risk of taking their own lives.
While the UK may have one of the lowest rates of suicide in the world, it is still the biggest cause of death in men under 45, so being able to make a Structured Professional Judgement about who might attempt suicide and knowing how to intervene is vitally important.
In a world that's changing fast, the Long Term Ecological Research (LTER) Network can seem almost an anachronism. Yet the patience and persistence that have generated 40 years of careful, reliable science about the Earth's changing ecosystems may prove to be just what's needed in this rapidly shifting world. We can't wait for a crystal ball -- and we don't have to. By harnessing decades of rich data, scientists are beginning to forecast future conditions and plan ways to manage, mitigate, or adapt to likely changes in ecosystems that will impact human economies, health and wellbeing.
PHILADELPHIA and MELBOURNE, Australia -- (May. 17, 2021) -- A team of scientists from The Wistar Institute in Philadelphia and the Peter MacCallum Cancer Center in Melbourne, Australia, discovered a new checkpoint mechanism that fine-tunes gene transcription. As reported in a study published in Cell, a component of the Integrator protein complex tethers the protein phosphatase 2A (PP2A) to the site of transcription allowing it to stop the activity of the RNA polymerase II enzyme (RNAPII).
Viruses attack the body by sending their genetic code -- DNA and RNA -- into cells and multiplying. A promising class of therapeutics that uses synthetic nucleic acids to target and shut down specific, harmful genes and prevent viruses from spreading is gaining steam.
However, only a handful of siRNA, or other RNA interference-based therapeutics have been approved. One of the main problems is getting the siRNA into the body and guiding it to the target.
One of the especially dangerous health risks of being extremely overweight occurs when an obese person begins to accumulate fat in their liver.
This condition--non-alcoholic fatty liver disease (NAFLD)--is the world's most common chronic liver disease and is the primary underlying cause for liver transplants in children and adults. Without such transplants, which are available to only a small percentage of patients, NAFLD over time can be fatal. In fact, (excluding alcohol-related liver damage) more than 30,000 people a year die from NAFLD.
PITTSBURGH, May 17, 2021 - Monoclonal antibodies, a COVID-19 treatment given early after coronavirus infection, cut the risk of hospitalization and death by 60% in those most likely to suffer complications of the disease, according to an analysis of UPMC patients who received the medication compared to similar patients who did not.
Imagine an entire twenty storey concrete building which can store energy like a giant battery. Thanks to unique research from Chalmers University of Technology, Sweden, such a vision could someday be a reality. Researchers from the Department of Architecture and Civil Engineering recently published an article outlining a new concept for rechargeable batteries - made of cement.
The nanophotonics-based LiDAR technology developed by a POSTECH research team was presented as an invited paper in Nature Nanotechnology, the leading academic journal in the field of nanoscience and nanoengineering.
PULLMAN, Wash. -- Washington State University researchers have developed an innovative way to convert plastics to ingredients for jet fuel and other valuable products, making it easier and more cost effective to reuse plastics.
A valve invented by engineer Nikola Tesla a century ago is not only more functional than previously realized, but also has other potential applications today, a team of researchers has found after conducting a series of experiments on replications of the early 20th-century design.
Its findings, reported in the journal Nature Communications, suggest that Tesla's device, which he called a "valvular conduit," could harness the vibrations in engines and other machinery to pump fuel, coolants, lubricants, and other gases and liquids.
