Western University researchers make breakthrough in arthritis research

Researchers at Western University have made a breakthrough that could lead to a better understanding of a common form of arthritis that, until now, has eluded scientists.

According to The Arthritis Society, the second most common form of arthritis after osteoarthritis is "diffuse idiopathic skeletal hyperostosis" or DISH. It affects between six and 12 percent of North Americans, usually people older than 50. DISH is classified as a form of degenerative arthritis and is characterized by the formation of excessive mineral deposits along the sides of the vertebrae in the neck and back. Symptoms of DISH include spine pain and stiffness and in advanced cases, difficulty swallowing and damage to spinal nerves. The cause of DISH is unknown and there are no specific treatments.

Now researchers at Western University's Bone and Joint Initiative, with collaborator Doo-Sup Choi at the Mayo Clinic in Rochester, Minnesota have discovered the first-ever mouse model of this disease. The research is published online in the Journal of Bone and Mineral Research.

"This model will allow us for the first time to uncover the mechanisms underlying DISH and related disorders. Knowledge of these mechanisms will ultimately allow us to test novel pharmacological treatments to reverse or slow the development of DISH in humans," says corresponding author Cheryle Séguin of the Skeletal Biology Laboratories and the Department of Physiology and Pharmacology at Western's Schulich School of Medicine & Dentistry.

Graduate student Derek Bone, working under the supervision of pharmacologist James Hammond, was studying mice that had been genetically modified to lack a specific membrane protein that transports adenosine when he noticed that these mice developed abnormal calcification (mineralization) of spinal structures.

Changes in the backbone of these mice were characterized by an interdisciplinary team which included: Sumeeta Warraich, Diana Quinonez, Hisataka Ii, Maria Drangova, David Holdsworth and Jeff Dixon. Their findings established that spinal mineralization in these mice resembles DISH in humans and point to a role for adenosine in causing abnormal mineralization in DISH.

These studies were funded by grants from the Canadian Institutes of Health Research and the Canadian Arthritis Network (CAN). Séguin is supported by a Network Scholar Award from The Arthritis Society and CAN.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
