Results of these studies appear in the March 11, 2008 issue of the Proceedings of the National Academy of Sciences.
These studies, led by Brian Kaspar, PhD, a principal investigator in the Center for Gene Therapy at The Research Institute and an assistant professor of Pediatrics at The Ohio State University, focus on a protein called follistatin (FS). Using a single injection, gene-delivery strategy involving FS, investigators treated the hind leg muscles of mice. Results showed increased muscle size and strength, quadruple that of mice treated with proteins other than FS. The muscle enhancements were shown to be well-tolerated for more than two years.
According to Dr. Kaspar, increased muscle mass and strength were also evident when this strategy was tested using a model of DMD. Apart from the injected hind leg muscles, strengthening effects were also shown in the triceps. In addition, fibrosis, abnormal formation of scar tissue and a hallmark of muscular dystrophy, was decreased in FS-treated animals.
“We believe this new FS strategy may be more powerful than other strategies due to its additional effects, including its ability to reduce inflammation,” said Dr. Kaspar.
The strategy showed no negative effects on the heart or reproductive ability of either males or females. The results were also replicated in older animals, suggesting that this strategy could be useful in developing clinical treatments for older DMD patients.
“This research provides evidence of multiple potential treatment applications for muscle diseases including, but not limited to, muscular dystrophy,” said Jerry Mendell, MD, director of the Center for Gene Therapy at The Research Institute, a co-author on the study, and professor of Pediatrics in Neurology and Pathology at The Ohio State University. “These results offer promise for treatment of potentially any muscle-wasting disease, including muscle weakness due to other illnesses, aging, and inflammatory diseases such as polymyositis. Our next step is to pursue clinical trials.”
The Research Institute at Nationwide Children’s Hospital has a patent pending on the FS technique due to the major role it may play for muscular dystrophy treatment and other muscle-wasting diseases.

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...
