Scientists have developed biodegradable polymers that can mimic the ability of white blood cells to target inflamed blood vessel walls, according to a new study led by Ohio University researchers. The finding could be the first step in developing drugs that suppress specific sites of inflammation in medical conditions such as arthritis, heart disease and inflammatory bowel disease.
Researchers found that biodegradable beads coated with targeting molecules can travel through the bloodstream and effectively stick to the site of tissue inflammation, a symptom of various diseases, according to the study, which will be published in the Dec. 23 issue of the journal Proceedings of the National Academy of Sciences. Scientists are interested in drugs made from biodegradable polymers because they can be easily prepared, have a long shelf life and can be designed to release specific doses of medication, according to the study.
When the body suffers from a bacterial infection or a wound, the white blood cells, or leukocytes, adhere to the site to treat the problem. But in inflammatory diseases such as arthritis, heart disease or inflammatory bowel disease, leukocytes accumulate in an area where they arent needed and cause or progressively worsen the disease.

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...
