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.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
