The Moscow scientists have conducted clinical trials of a new method for treatment of deep burns of cornea. Their effort has been supported by the Russian Foundation for Basic Research.
Specialists of the Koltsov Institute of Developmental Biology, Russian Academy of Sciences, and the Gelmgolts Scientific Research Institute of Eye Diseases suggest that deep burns of cornea should be treated by transplanting artificial equivalent of stroma (the tissue directly underlying the cornea) on the affected area. The researchers have developed technique for preparation and transplantation of live equivalent of stroma (LES) and tested it in the clinic on patients with heavy burns of eyes. They managed to help the overwhelming majority of patients.
The share of burns among all eye traumas makes about 38 percent, with considerable proportion of cases involving cornea damage. The cornea is supported by the stroma connective tissue, which also gets damaged in case of deep burns. If the stroma is missing or significantly destroyed, the remaining cornea cells are unable to recover injuries as they have no support. Therefore, the major task in treating cornea defects is stroma recovery. This task is convenient to solve via tissue transfer. Foreign researchers suggest that cell culture taken from a healthy eye should be transplanted on the burnt area. However, such operation poses a serious trauma by itself, which is not always justified.

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...
