Infusing a naturally occurring anti-scarring agent called decorin into the damaged spinal cords of rats suppresses key molecules that block nerve regeneration after spinal cord injury, said Baylor College of Medicine (BCM) researchers in a study published today in the European Journal of Neuroscience.
The researchers are the first to use decorin to suppress inflammation and scar formation in spinal cord injuries. "Scar tissue that develops at sites of injury stops the regeneration of connections in the adult central nervous system," said Dr. Stephen Davies, lead author on the study and an assistant professor of neurosurgery and neurosciences at BCM. "Infusion of decorin into spinal cord injuries prevents the formation of proteoglycan rich scar tissue by suppressing inflammation."
Misaligned scar tissue that forms at spinal cord injuries physically blocks nerve regeneration and contains molecules called chondroitin sulfate proteoglycans that inhibit nerve fiber growth. Decorin inhibits the action of pro - inflammatory molecules released in spinal cord injuries, called transforming growth factors, which are thought to promote the formation of scar tissue.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
