“…It should be stressed that in humans the majority of calcium and phosphorus (90% and 99%, respectively) is stored in bones [12]. Additionally, there are data indicating that the ratio of calcium and phosphorus in the diet affects their intestinal absorption, renal filtration and availability for metabolic processes [6].…”

SummaryStudy aim: To evaluate energy, macronutrient, calcium, magnesium, and phosphate daily intake in young healthy Polish male students. Material and methods: Two hundred and sixteen participants were physical education students engaged in regular physical activity (about 9 h/week) and were recognized as physically active. One hundred and fourteen students were from other specializations participating in 1.5 h/week gymnastics classes and were recognized as sedentary. Body mass and height were measured using standard medical equipment. Body fat was evaluated from four skinfold measurements. In all subjects daily intake of energy, protein, fat, carbohydrates, calcium, magnesium and phosphate was briefly assessed from 24-hour food records taken over 4 days. Results: The active students' diet was characterized by significantly higher energy, macronutrient and mineral daily intake. Moreover, calcium to phosphorus and calcium to magnesium ratios in active subjects were higher than in sedentary ones. There was no significant difference between groups in protein or magnesium intake expressed per 1000 kcal. In contrast, daily intake of fat and phosphate expressed per 1000 kcal was significantly lower in the active students vs. sedentary ones (p < 0.001 and p < 0.05 for fat and phosphate, respectively). Active students were characterized by significantly higher carbohydrate and calcium intake per 1000 kcal in comparison with their sedentary counterparts (p < 0.001 for both variables). Conclusions:The dietary pattern of active students was found to be slightly but significantly better than that of their sedentary counterparts. However, in both groups it was far from being a healthy one.

“…Among all of the Fe-based alloys, Fe-Mn alloys have been proved to be the most promising ones in accelerating the corrosion rate of Fe with similar mechanical properties (i.e., Young's modulus and ultimate tensile strength) to 316L SS [51]. Moreover, Mn can play an important role in promoting the growth of new bone and connective tissues as well as reducing bone loss [52,53] which could increase its bioactivity in orthopedic and dental applications. However, Fe and its alloys have much higher mechanical properties than those of the human cortical bone (see Table 1), which keeps the stress shielding effect as a challenging issue to select them as a suitable candidate in the load-bearing locations, especially as bulk temporary implants.…”

Abstract:Owing to significant advantages of bioactivity and biodegradability, biodegradable metallic materials such as magnesium, iron, and zinc and their alloys have been widely studied over recent years. Metallic wires with superior tensile strength and proper ductility can be fabricated by a traditional metalworking process (drawing). Drawn biodegradable metallic wires are popular biodegradable materials, which are promising in different clinical applications such as orthopedic fixation, surgical staples, cardiovascular stents, and aneurysm occlusion. This paper presents recent advances associated with the application of biodegradable metallic wires used in dental and orthopedic fields. Furthermore, the effects of some parameters such as the surface modification, alloying elements, and fabrication process affecting the degradation rate as well as biocompatibility, bioactivity, and mechanical stability are reviewed in the most recent works pertaining to these materials. Finally, possible pathways for future studies regarding the production of more efficient biodegradable metallic wires in the regeneration of bone defects are also proposed.

“…23 Early animal experiments in chicks, poults, mice and pigs showed that Mo can stimulate early development in a dose-dependent manner. [23][24][25][26] Moreover, Mo-containing metals and alloys (for example, Ti-7.5Mo, 27 Ti-15Mo-1Bi, 28 Co-Cr-Mo 29 and Ti-12Mo-6Zr-2Fe 30 ) exhibited excellent mechanical properties and biocompatibility and have been widely used as orthopedic and dental implants. However, to the best of our knowledge, studies of Mo-containing tissue engineering scaffolds for bone regeneration have not yet been reported.…”

The treatment of malignant bone tumors is a significant clinical challenge because it requires the simultaneous removal of tumor tissues and regeneration of bone defects, and bifunctional three-dimensional (3D) scaffolds that function in both tumor therapy and tissue regeneration are expected to address this need. In this study, novel bifunctional scaffolds (MS-AKT scaffolds) were successfully fabricated by combining a 3D printing technique with a hydrothermal method. During the hydrothermal process, MoS 2 nanosheets were grown in situ on the strut surface of bioceramic scaffolds, endowing them with photothermal therapeutic potential. Under near-infrared (NIR) irradiation, the temperature of the MS-AKT scaffolds rapidly increased and was effectively modulated by varying the MoS 2 content, scaffold sizes and laser power densities. The photothermal temperature significantly decreased the viability of osteosarcoma cells and breast cancer cells and inhibited tumor growth in vivo. Moreover, the MS-AKT scaffolds supported the attachment, proliferation and osteogenic differentiation of bone mesenchymal stem cells and induced bone regeneration in vivo. This bifunctional scaffold, which treats the tumor and facilitates bone growth, offers a promising clinical strategy to treat tumor-induced bone defects. This proof-of-concept study demonstrates the feasibility of localized tumor therapy and tissue regeneration in diverse tissue engineering applications using multifunctional biomaterials.
