Duke University Medical Center researchers have uncovered a strong relationship between the severity of heart disease and the level of endothelial progenitor cells circulating in the bloodstream. This relationship, if confirmed by ongoing studies, could represent an important new diagnostic and therapeutic target for the treatment of coronary artery disease, they said.

These endothelial progenitor cells (EPC) are produced in the bone marrow, and one of their roles is to repair damage to the lining of blood vessels. Duke cardiologists believe that one cause of coronary artery disease is an increasing inability over time of these EPCs to keep up with the damage caused to the arterial lining, or endothelium.
"In our study we found that patients with multi-vessel disease had many fewer EPCs, which supports our hypothesis that these cells play an important role in protecting blood vessels," said cardiologist Geoffrey Kunz, M.D., of the Duke Clinical Research Institute. "If you dont have enough of the cells, the ongoing damage to the endothelium from traditional risk factors occurs faster than the bodys ability for repair."

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...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
