The fact that infections among adults can increase the risk of heart attacks and strokes is now well established by several hundred scientific studies. Both heart attacks and strokes are expressions of arteriosclerosis (thickening of the arteries, previously termed hardening of the arteries). New research from the Section for Pediatric Cardiology in Lund indicates that infections can also contribute to the early development of arteriosclerosis even in childhood.
Doctor Petru Liuba shows in a newly submitted dissertation at Lund University that children who have been admitted to the hospital for severe urinary and respiratory infections developed thickening of the inner walls of the arteries after a period of illness. The study is the first in the world to show, with the help of ultrasound, that acute infections in children can be followed by such early signs of arteriosclerosis.
Thickening of the arteries is a disease that is connected to a number of factors, including high blood pressure, high cholesterol content in the blood, diabetes, inflammatory diseases like rheumatism, and a hereditary proneness to cardiovascular diseases. But these risk factors explain less than half of all cases, and infections are now being seen as a further partial explanation.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
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.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
