Effects of different concentrations of degradation products of magnesium and magnesium alloys on osteogenic precursor cells
<p><span><span><span><span><span><span><span><span><span><span><span>Magnesium-based alloys have a great potential to become orthopedic degradable materials for internal fixation implants, and magnesium-based implants have been shown to influence the surrounding bone structure. To understand the effects of magnesium-based implants on bone healing and remodeling, we investigated the effects of the extracts of pure magnesium and three magnesium alloys on the proliferation and differentiation of osteogenic precursor cells in vitro. MC3T3-E1 cells were selected as the study objects. Cell culture medium was used to extract the aforementioned metal materials, and the degradation products and extracts were subjected to a compositional analysis. Subsequently, the extracts were diluted to different concentrations for cell proliferation/differentiation cultures. The MC3T3-E1 proliferation and differentiation were evaluated based on the cell viability, alkaline phosphatase activity, total protein content, and cellular ability to form calcified nodules in the extracellular matrix.The magnesium ions enhanced and opposed cell proliferation and differentiation in a concentration-dependent manner. Higher concentrations of metal extracts that degraded faster (indicating higher levels of Mg ions) had an adverse effect on cell proliferation, and extracts with a lower concentration or slower degradation promoted cell proliferation. When slightly elevated, the Mg ions in the extracts suppressed the osteogenic differentiation and extracellular matrix mineralization of the cells, while they promoted these processes when present beyond a certain concentration. In cases of similar Mg ion contents, the extracts that contained Zn ions were better in promoting cell proliferation and extracellular matrix mineralization. </span></span></span></span></span></span></span></span></span></span></span></p>
Data from: Enhancement of apoptosis by titanium alloy internal fixations during microwave treatments for fractures: an animal study
Objective: Microwaves are used in one method of physical therapy and can increase muscle tissue temperature which is useful for improving muscle, tendon and bone injuries. In the study, we sought to determine whether titanium alloy internal fixations influence apoptosis in tissues subjected to microwave treatments at 2,450 MHz and 40 W during the healing of fractures because this issue is not yet fully understood. Methods: In this study, titanium alloy internal fixations were used to treat 3.0-mm transverse osteotomies in the middle of New Zealand rabbits' femurs. After the operation, 30-day microwave treatments were applied to the 3.0 mm transverse osteotomies 3 days after the operation. The changes in the temperatures of the muscle tissues in front of the implants or the 3.0 mm transverse osteotomies were measured during the microwave treatments. To characterize the effects of titanium alloy internal fixations on apoptosis in the muscles after microwave treatment, we performed TUNEL assays, fluorescent real-time (quantitative) PCR, western blotting analyses, reactive oxygen species (ROS) detection and transmission electron microscopy examinations. Results: The temperatures were markedly increased in the animals with the titanium alloy implants. Apoptosis in the muscle cells of the implanted group was significantly more extensive than that in the non-implanted control group at different time points. Transmission electron microscopy examinations of the skeletal muscles of the implanted groups revealed muscular mitochondrial swelling, vacuolization. ROS, Bax and Hsp70 were up-regulated, and Bcl-2 was down-regulated in the implanted group. Conclusion: Our results suggest that titanium alloy internal fixations caused greater muscular tissue cell apoptosis following 2,450 MHz, 40 W microwave treatments in this rabbit femur fracture models.

High-throughput investigation of ferrite growth kinetics in graded ternary Fe-C-X alloys
<p>The composition dependence of ferrite growth kinetics in Fe-C-X ternary alloyed steels, where X = Ni, Mn, Mo, Cr, Si, was investigated using a high-throughput approach. Compositionally graded samples were subjected to in situ time- and space-resolved X-ray diffraction during intercritical annealing. To this end, diffusion couples were created between a binary Fe-C and different Fe-C-X alloys, using hot uniaxial compression and high temperature diffusion treatments. In-situ high-energy X-ray diffraction experiments were performed to collect ferrite growth kinetics along the composition gradient of the diffusion couples. A large dataset describing the austenite-to-ferrite phase transformation kinetics was generated using a very limited number of experiments. This dataset of unprecedented size was compared to the kinetics predicted by the classical local-equilibrium (LE) and para-equilibrium (PE) models as well as a modified version of the three-jump solute drag (SD) model, which accounts for the different interactions between the elements present at the austenite/ferrite interface. The comparison showed that both LE and PE models fail to capture the effect of both composition and temperature on the kinetics of ferrite growth for the different Fe-C-X systems. The SD model calculations matched experimental transformation kinetics at all investigated temperatures and over almost all the investigated composition ranges of Si, Cr, Mn, Ni, and Mo.</p>
