Various forms of human muscular dystrophy result from mutations in genes encoding proteins of the nuclear envelope. A new paper in the February 15th issue of G&D reveals how.
Ten human hereditary laminopathies, including Emery-Dreifuss muscular dystrophy (EDMD), are associated with mutations in the LMNA gene that codes for the nuclear filament proteins, lamins A and C. Dr. Brain Kennedy and colleagues at the University of Washington have used a mouse model of EDMD to elucidate the mechanism by which altered expression of A-type lamins causes progressive muscular degeneration.
Adult skeletal muscle is derived from satellite stem cells, known as myoblasts, which differentiate into mature skeletal muscle cells. While several different types of proteins are known to be involved in myogenesis, the role of A-type lamins in muscle differentiation has remained unclear. Dr. Kennedy and colleagues used Lmna-deficient cells, as well as siRNA-mediated knock-down of Lmna and emerin (a lamin-associated protein) to study the affect of decreased A-type lamin or emerin expression on myoblast differentiation.

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...
