An under-recognized and usually asymptomatic condition called subclavian artery stenosis – an obstruction of arteries located under the clavicle, or collarbone – is important in the diagnosis and treatment of high blood pressure, according to a study by researchers at the University of California, San Diego (UCSD) School of Medicine and Northwestern University’s Feinberg School of Medicine in Chicago.
Published in the August 4, 2004 issue of the Journal of the American College of Cardiology, the study investigated the prevalence of subclavian artery stenosis (SS) in 4,223 individuals, and determined risk factors.
SS was found in approximately 2 percent of individuals without cardiovascular problems and in 7 percent of those currently under a doctor’s care for cardiovascular conditions. Patients most at risk were those with current or past smoking histories, higher than normal systolic blood pressure, lower levels of HDL cholesterol, and the presence of peripheral arterial disease (PAD), which is characterized by narrowing of the arteries in the legs and arms due to build-up of atherosclerotic plaque on vessel walls. Patients with PAD were found to be at a fivefold greater risk of having SS.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
