By combining stem cell science with orthopedic surgery, a team of researchers at the University of British Columbia and Vancouver Coastal Health Research Institute aims to reduce the 10 per cent failure rate in hip replacements and make repeat replacements and other joint repairs obsolete within 10-15 years.
With $1.5 million over five years in funding from the Canadian Institutes for Health Research, a group of seven UBC scientists will explore how stem cells – the bodys "master cells" that can reproduce and develop many mature functional cells – can be used to regenerate bone cells to better secure artificial joints and other bone replacement structures. "Were very excited about the potential for long-term success for patients who need repeat surgery to repair or replace bone," says Fabio Rossi, UBC assistant professor of medical genetics and Canada Research Chair in Regenerative Medicine. "By using a well-understood stem cell and available technologies, we can accelerate research and have our discoveries quickly incorporated into patient care."
The team will create a new fixative mixture that combines minerals and slow-release growth factors. The mixture will be seeded with the patients own mesenchymal stem cells – a type of stem cell that is easily extracted from adult bone marrow and capable of manufacturing bone cells and connective tissue. This "living glue" will form a strong, organic environment to secure artificial joints, vertebrae or other replacement structures where the original replacement has failed.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
