Selective Removal of Heavy Metal Ions from Waters and Waste Waters Using Ion...

The primary role of the ZIP13 metal transporter in flies is to move iron ions out of cells, rather than moving zinc ions into cells, as is the case in human cells.

OBJECTIVES Patient-specific (PS) implantation surgical technology has been introduced in recent years and a gradual increase in the associated number of surgical cases has been observed. PS technology uses a patient's own geometry in designing a medical device to provide minimal bone resection with improvement in the prosthetic bone coverage. However, whether PS unicompartmental knee arthroplas...

Only in Japan, there are about 82,000 upper limb amputees (Ministry of Health, Labour and Welfare, 2005). Using upper limb prostheses could restore the function for them, thus improve significantly the quality of their activities of daily living [ADL]. Compared with below-elbow prostheses, shoulder prostheses are left behind in their development, due to high degrees of freedom [DOF] required, w...

The tribological performance of artificial hip joints is a critical issue for their success, because adverse tissue reaction to wear debris causes loosening and failure. Many studies on wear and lubrication of hip prostheses have been published in the last 10 years, mostly on experimental tests. Theoretical/ numerical models have been proposed for investigating geometrical and material paramete...

In 33 dogs we implanted femoral stems made either of carbon composite, some coated with hydroxyapatite, or of titanium alloy with a porous coating. Osseointegration was greater in the hydroxyapatite-coated than in the un-coated stems (p less than 0.001). Push-out tests, at an average of 7.2 months after implantation, showed a six-fold increase in interface shear strength and a twelve-fold incre...

Introduction. Total knee replacement is the most efficient method of treating end-stage osteoarthritis joint. The surgery aims to relieve patients pain, restore range motion and improve patients’ quality lives. Prostheses design still being modified improved through cooperation between orthopaedic surgeons engineers. Some modern solutions aimed fit native anatomy as much possible are anatomic s...

The wrist plays an important role for the function of the human hand. The wrist joint is a complicated anatomical unit, consisting of various bones, ligaments and muscles. The distal and proximal joints combined with the rotation of the forearm excite movements at various levels that bring the hand into different positions. Apart from the rotation, the newly developed wrist with low constructio...

Periprosthetic joint infection (PJI) is a well-described complication of arthroplasty. Pasteurella multocida rare cause PJI that predominantly occurs after exposure to animals, primarily cats and dogs. There are only two described cases in the literature where multiple prostheses were simultaneously infected with P. hematogenous dissemination. We present third case synchronous prosthetic joints...

Prosthetic joint infections are a major challenge in total joint arthroplasty, especially in times of accumulating drug resistancies. Even though predictive risk classifications are a widely accepted tool to define a suitable treatment protocol a classification is still missing considering the difficulty in treating the -causative pathogen antibiotically. In this study, we present and evaluate ...
