This is shown by Umeå University researchers Tuija Athanassiadis and Karl-Gunnar Westberg, in collaboration with Canadian associates, in the scientific journal PLoS One.
Muscles have sensory organs called muscle spindles. Their task is to inform the brain of changes in muscle length. Muscle spindles therefore contain a special type of large diameter nerve filaments that signal stretch of the muscle. The Umeå scientists’ studies show that muscle spindles also contain fine nerve filaments with pain receptors.
When a muscle is damaged as a result of overloading, these pain receptors are activated by the release of a signal substance from the neighboring stretch-sensitive nerve filaments in the muscle spindle.
It was previously believed that the pain receptors in muscles were exclusively found in the membranes that surround the muscles or in connection with the blood vessels in the muscle. With these new findings the Umeå researchers are drawing attention to a hitherto unknown and interesting mechanism. Damage to the stretch-sensitive nerve filaments of the muscle spindle may contribute to and sustain chronic pain in jaw muscles as well as in other muscles.Reference:

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.
