Researchers say the concentration of two molecules called non-coding RNAs in blood were associated with mild cartilage damage in 30 patients who were one year removed from reconstruction surgery to repair an anterior cruciate ligament, or ACL, injury.
The findings are described as significant in the ongoing and tedious search of biomarkers for osteoarthritis, the most common form of arthritis that afflicts an estimated 27 million Americans aged 25 and older. It is caused by the normal aging process or wear and tear of a joint.
The study is being presented Saturday at the annual Orthopaedic Research Society in San Francisco.
"Our results suggest we have identified a long-awaited biomarker for this leading cause of disability," says Gary Gibson, Ph.D., director of Henry Ford's Bone and Joint Center and the study's lead author.
"For various pathology reasons associated with the variability of the disease and challenging blood biochemistry, developing a biomarker for osteoarthritis has been very elusive. But we believe our work shows great promise. The next step is to expand the number of patients studied and determine whether the degree in blood concentration can determine if the cartilage damage will worsen over time.
"Our ultimate goal is to develop a biomarker that can be used in the development of future treatments to prevent the progression of the disease," he added.
The study, a collaboration of Henry Ford, University of Guelph in Ontario and University of Toronto, involved 121 Canadian patients from 2006-2011. Patients underwent an MRI and blood test one year after ACL surgery.
The study was funded by the National Institutes of Health and Canadian Institutes of Health Research and Canadian Arthritis Network.

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...
