The cells that line the arteries are able to produce C-reactive protein, according to a study funded by the National Institutes of Health and published in the April issue of American Journal of Pathology.
C-reactive protein is a risk marker for heart disease and is known to be produced in the liver, but UC Davis School of Medicine researchers Ishwarlal Jialal and Sridevi Devaraj found that endothelial cells also produce C-reactive protein, a key finding that helps to explain how plaque formation is initiated. This is particularly important because endothelial cells are supposed to protect the arteries from C-reactive protein.
"This is an extremely important finding," says Jialal, professor of pathology and internal medicine and director of the Laboratory for Atherosclerosis and Metabolic Research at UC Davis Medical Center. "We have convincingly demonstrated in this paper that aortic and coronary artery endothelial cells produce and secrete C-reactive protein. We also showed within the artery, mature white cells, called macrophages, make chemical messengers, cytokines, which enhance the C-reactive protein secretion by endothelial cells at least 10-fold.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
