Their study was recently published in the "International Journal of Molecular Sciences".
A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's latest in-vitro results, published in Biomaterials Science, suggest that the…
Our body is able to treat many injuries and wounds all by itself. Self-healing powers repair skin abrasions and enable bones to grow back together. However, doctors often have to lend a helping hand to repair bones after a fracture or due to a defect. Increasingly, bone replacement materials are being used, which partially or completely restore the form and function of the bone at the site of the…
Austria-based cochlear and hearing implants technology company Med-El has become one of the first manufacturers worldwide, and the first and only hearing implant manufacturer in the world, to be granted European Medical Device Regulation (MDR) certification. The company made an initial announcement on the newly earned certification after making an early commitment to adopt the MDR in 2016. For…
Researchers at the Hong Kong University of Science and Technology (HKUST), the University of California, Berkeley and Lawrence Berkeley National Laboratory are developing an artificial eye with capabilities close to its human model. The research team published their work on the biomimetic eye in the journal Nature. “Watching sci-fi series such as Star Trek and I, Robot, I thought about making a…
More than 200,000 patients undergo hip replacement surgery in Germany each year. To avoid complications and extend the lifespan of the artificial joint, the implants must be fitted precisely in the acetabulum (hip socket). The procedure, particularly milling the acetabulum, is not only difficult but also the technique is difficult to teach and train.

Periprosthetic joint infection (PJI) is on the increase internationally. In Germany, for example, around 14,500 cases of PJI in hip and knee replacements occur annually. 5,100 of those are caused by multidrug resistant pathogens. ‘Eighty-seven percent of those affected die within five years,’ orthopaedic surgeon Professor Rudolf Ascherl MD pointed out during the Heraeus Symposium held at the…
Every year, a lack of vaccination leads to about 1.5 million preventable deaths, primarily in developing nations. One factor that makes vaccination campaigns in those nations more difficult is that there is little infrastructure for storing medical records, so there’s often no easy way to determine who needs a particular vaccine. Researchers at the Massachusetts Institute of Technology (MIT)…
