Introduction: Osteosarcoma of the pelvis poses challenges in surgical resection due to its anatomical location and extensive nature. This case report focuses on the clinical presentation and therapeutic outcomes of a 20-year-old patient with osteosarcoma of the right iliac bone. The study highlights the efficacy of 3D printing technology in creating customized implants for improved surgical outcomes.
Case Report: The case report presents the clinical presentation, management, and outcomes of a patient with osteosarcoma of the right iliac bone. It emphasizes the impact of surgical resection extent and endoprosthetic reconstruction. The study highlights the advantages of 3D printing technology in creating customized implants that accurately fit the remaining bone. Limb-sparing surgery is advocated for better functional and psychological outcomes compared to amputation. The report also emphasizes the need for further research on alternative composite materials and discusses the limitations of 3D printing technology in orthopedics.The limitations of 3D printing, such as mechanical safety and material restrictions, are discussed, calling for future advancements to improve the reliability and effectiveness of 3D-printed implants in orthopedics.
Conclusion: The present case report provides valuable perspectives into the efficacious management of pelvic osteosarcoma and underscores the distinctive advantages of 3D printing technology in improving surgical results. Limb-sparing surgery demonstrates enhanced functional and psychological outcomes compared to amputation. Utilizing 3D custom-made implants, significantly reduces the likelihood of revision surgeries attributed to implant failure, improves the surgical outcome and precision.

Despite advancements in engineered heart tissue (EHT), challenges persist in achieving accurate dimensional accuracy of scaffolds and maturing human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), a primary source of functional cardiac cells. Drawing inspiration from cardiac muscle fiber arrangement, a three-dimensional (3D)-printed multi-layered microporous polycaprolactone (PCL) scaffold is created with interlayer angles set at 45° to replicate the precise structure of native cardiac tissue. Compared with the control group and 90° PCL scaffolds, the 45° PCL scaffolds exhibited superior biocompatibility for cell culture and improved hiPSC-CM maturation in calcium handling.

Repair of infectious bone defects remains a serious problem in clinical practice owing to the high risk of infection and excessive reactive oxygen species (ROS) during the early stage, and the residual bacteria and delayed Osseo integrated interface in the later stage, which jointly creates a complex and dynamic microenvironment and leads to bone non-union. The melatonin carbon dots (MCDs) possess antibacterial and osteogenesis abilities, greatly simplifying the composition of a multifunctional material. Therefore, a multifunctional hydrogel containing MCDs (GH-MCD) is developed to meet the multi-stage and complex repair needs of infectious bone injury in this study.

Background: Double outlet right ventricle (DORV) is a challenging congenital cardiac lesion to surgically master. We utilize computed tomography-guided-three-dimensional (3D) modeling/printing and novel in-house software to delineate anatomical relationships providing operative insight into the surgical approach. Our intent is to highlight this and showcase our technology.

Production of alternative proteins is crucial for the development of future protein resources. This study explored the creation of sustainable animal resources by combining extrusion molding and three-dimensional (3D) printing technologies. Extrusion effectively organizes vegetable proteins at high temperatures and pressures to replicate meat-like textures, and high-moisture extrusion successfully mimics the fiber structure of conventional meat.

Introduction: Magnetic resonance imaging (MRI) is essential for brain imaging, but conventional methods rely on qualitative contrast, are time-intensive, and prone to variability. Magnetic resonance finger printing (MRF) addresses these limitations by enabling fast, simultaneous mapping of multiple tissue properties like T1, T2. Using dynamic acquisition parameters and a precomputed signal dictionary, MRF provides robust, qualitative maps, improving diagnostic precision and expanding clinical and research applications in brain imaging.
