ABSTRACT Scaffolds of polycaprolactone (PCL) and PCL composites reinforced with β‐tricalcium phosphate (β‐TCP) were manufactured aiming potential tissue engineering applications. They fabricated using a three‐dimensional (3D) mini‐screw extrusion printing, novel additive manufacturing process, which consists in an head coupled to 3D printer based on the Fab@Home equipment. Thermal properties obtained by differential scanning calorimetry thermogravimetric analyses. morphology observed...
The aim of this study is to present the development a new technique obtain 3D models using photogrammetry by mobile device and free software, as method for making digital facial impressions patients with maxillofacial defects final purpose printing prostheses.With use device, software photo capture protocol, 2D captures anatomy patient defect were transformed into model. resultant evaluated visual technical integrity. process described analyzed clinical usability.Generating make face was...
Cartilage tissue presents low self-repair capability and lesions often undergo irreversible progression. Structures obtained by engineering, such as those based in extrusion bioprinting of constructs loaded with stem cell spheroids may offer valuable alternatives for research therapeutic purposes. Human mesenchymal stromal (hMSC) can be chondrogenically differentiated faster more efficiently than single cells. This approach allows obtaining larger tissues a rapid, controlled reproducible...
Development of methods for scalable biofabrication uniformly sized tissue spheroids is essential spheroid-based bioprinting large size and organ constructs. The most recent technique spheroid fabrication employs a micromolded recessed template prepared in non-adhesive hydrogel, wherein the cells loaded into self-assemble due to gravitational force. In this study, we present an improved version technique. A new mold was designed enable generation 61 microrecessions each well 96-well plate....
Background: Computer‐aided dental implant placement seems to be useful for placing implants by using a flapless approach. However, evidence supporting such applications is scarce. The aim of this study evaluate the accuracy and complications that arise from use selective laser sintering surgical guides immediate definitive prosthesis installation. Methods: Sixty 12 prostheses were installed in patients (four males eight females; age range: 41 71 years). Lateral (coronal apical) angular...
Porous scaffolds are biocompatible and bioactive temporary substrates. They should present appropriated microstructure, mechanical properties surface for guiding bone tissue regeneration. In this work, of Poly(3-hydroxybutyrate) (PHB) were printed by Selective Laser Sintering (SLS). The effect scan spacing (SS) powder layer thickness (PLT) on the morphology, dimensional deviations related to digital model sintered was evaluated. Curling observed in first built layers scaffolds, mainly with...
One of the most applied strategies in tissue engineering consists development 3D porous scaffolds with similar composition to specific tissue. In fact, microstructure influences final structure growing this study, multi-layered PCL were produced modified Fab@home FDM printer order analyze influence extrusion technology (filament or powder head) and process parameters on deposited material. particular, dimensions uniformity both filament grid analyzed understand so as optimize production technology.
Materials, such as biopolymers, can be applied to produce scaffolds mechanical support for cell growth in regenerative medicine. Two examples are polycaprolactone (PCL) and poly (lactic-co-glycolic acid) (PLGA), both used this study evaluate the behavior of umbilical cord-derived mesenchymal stem cells. The were produced by 3D printing technique using PCL a polymer covered with PLGA fibers obtained electrospinning. cells seeded three concentrations: 8.5 × 103; 25.5 103 51.0 on two surfaces...
Biofabrication is an incipient and fast-growing field of research that continues to develop groundbreaking innovations. Considerable progress has also been made in additive manufacturing technologies, which are used for the production complex geometry using biomaterials, such as scaffolds and, most recently, bioink-based structures. Some topics related these new breakthroughs tissue engineering bioprinting will be discussed. Additionally, obtained experimental results this work contribute...
Abstract Background Nerve injuries are debilitating, leading to long-term motor deficits. Remyelination and axonal growth supported enhanced by factor cytokines. Combination of nerve guidance conduits (NGCs) with adipose-tissue-derived multipotent mesenchymal stromal cells (AdMSCs) has been performing promising strategy for regeneration. Methods 3D-printed polycaprolactone (PCL)-NGCs were fabricated. Wistar rats subjected critical sciatic damage (12-mm gap) divided into sham, autograft, PCL...

Objetivo: Descrever os principais protocolos de atendimento pré-hospitalar AVC isquêmico e hemorrágico, destacando as diferenças no manejo inicial desafios enfrentados pelas equipes emergência. Metodologia: Trata-se revisão narrativa da literatura caráter qualitativo. A coleta dados foi realizada nas...
Os laboratórios de inovação constituem um espaço experimentação com o objetivo principal promover melhorias em setores considerados críticos na gestão pública. O desta pesquisa é fazer levantamento bibliométrico acerca dos no setor público, usando como base dados a Web of Science e Portal Periódico da Capes. Para tanto, realizou-se uma análise bibliométrica das publicações disponíveis entre os anos 2018 2024. Dessa forma, desprenderam-se esforços analíticos para entendimento compreensão...
Introduction: The practice of breastfeeding is influenced by several social determinants health (SDH), such as maternal age, education, family income, and insertion in the labor market. This study, carried out coastal municipalities state Alagoas, Brazil, seeks to understand how these variables impact type breastfeeding, considering their associations with early weaning continuity exclusive breastfeeding. analysis shows that older mothers low income are more likely start mixed or partial...
