MDCT angiography can potentially help determine which patients with narrowed carotid arteries are at greater risk of having a stroke, a new study shows. This information could help identify which patients need surgery and which can be treated with less invasive procedures.
The study reviewed 31 patients who had greater than 60% carotid artery stenosis—18 had symptoms of carotid artery disease, including a transient or permanent brief episode s of neurologic dysfunction, while 13 had no history of stroke-related symptoms. All patients underwent MDCT angiography, to determine and the density of the plaque in the carotid artery was determined. “We found that patients with calcified (more dense) plaques were 21 times less likely to have had symptoms of stroke th a en those with noncalcified plaques,” said Kiran R. Nandalur, MD, at the University of Virginia Health System.
Currently the American Heart Association recommends surgery for any patient patients with carotid artery stenosis greater than 60% , provided that the patient is well enough to have the surgery, surgery is associated with low complications at the respective institution, Dr. Nandalur said. However, “our study suggests that patients who have no symptoms and calcified plaques could potentially be treated less aggressively , possibl y with just medicine instead , although larger prospective studies need to be done to confirm these results.”

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
