    Abstract While three-dimensional (3D) printing excels at fabricating static constructs, it fails to emulate the dynamic behavior of native tissues or the temporal programmability desired for medical devices. Four-dimensional (4D) printing is an advanced additive manufacturing technology capable of fabricating constructs that can undergo pre-programmed changes in shape, property, or functionality when exposed to specific stimuli. In this Perspective, we summarize the advances in materials chemistry, 3D printing strategies, and post-printing methodologies that collectively facilitate the realization of temporal dynamics within 4D-printed soft materials (hydrogels, shape-memory polymers, liquid crystalline elastomers), ceramics, and metals. We also discuss and present insights about the diverse biomedical applications of 4D printing, including tissue engineering and regenerative medicine, drug delivery,

    Abstract Three-dimensional (3D) printing of bone scaffolds using digital light processing (DLP) bioprinting technology empowers the treatment of patients suffering from bone disorders and defects through the fabrication of cell-laden patient-specific scaffolds. Here, we demonstrate the visible-light-induced photo-crosslinking of methacrylate-κ-carrageenan (MA-κ-CA) mixed with bioactive silica nanoparticles (BSNPs) to fabricate 3D composite hydrogels using digital light processing (DLP) printing. The 3D printing of complex bone structures, such as the gyroid, was demonstrated with high precision and resolution. DLP-printed 3D composite hydrogels of MA-κ-CA-BSNP were prepared and systematically assessed for their macroporous structure, swelling, and degradation characteristics. The viscosity, rheological, and mechanical properties were also investigated for the influence of nanoparticle incorporation in the MA-κ-CA hydrogels. The

    Abstract Emerging four-dimensional (4D) printing strategies offer improved alternatives to conventional three-dimensional (3D)-bioprinted structures for better compliance and simplicity of application for tissue engineering. Little is reported on simple 3D-bioprinted structures prepared by digital light processing (DLP) that can change shape-to-complex constructs (4D bioprinting) in response to cell-friendly stimuli, such as hydration. In the current research work, a bioink consisting of a blend of gelatin methacryloyl (GelMA) and poly(ethylene glycol) dimethacrylate (PEGDM) with a photoinitiator and a photoabsorber was developed and printed by DLP-based 3D bioprinting operated with visible light (405 nm). The 3D-bioprinted constructs combined with differential cross-linking due to photoabsorber-induced light attenuation were leveraged to realize structural anisotropy, which led to rapid shape deformation (as low as ≈30 min) upon hydration. The sheet thickness influenced the degree of curvature, whereas the incorporation of angled strands provided control of the deformation of the 3D-printed structure. The 4D-bioprinted gels supported the viability and proliferation of cells. Overall, this study introduces a cytocompatible bioink formulation for 4D bioprinting to yield shape-morphing, cell-laden hydrogels for tissue engineering.

    Abstract Bacterial contamination of implant surfaces is one of the primary causes of their failure, and this threat has been further exacerbated due to the emergence of drug-resistant bacteria. Nanostructured mechanobactericidal surfaces that neutralize bacteria via biophysical forces instead of traditional biochemical routes have emerged as a potential remedy against this issue. Here, we report on the bactericidal activity of titania nanotubes (TNTs) prepared by anodization, a well-established and scalable method. We investigate the differences in bacterial behavior between three different topographies and demonstrate the applicability of this technique on complex three-dimensional (3D) geometries. It was found that the metabolic activity of bacteria on such surfaces was lower, indicative of disturbed intracellular processes. The differences in deformations of the cell wall of Gram-negative and positive bacteria were investigated from electron micrographs Finally, nanoindentation experiments show that the nanotubular topography was durable enough against forces typically experienced in daily life and had minimal deformation under forces exerted by bacteria. Our observations highlight the potential of the anodization technique for fabricating mechanobactericidal surfaces for implants, devices, surgical instruments, and other surfaces in a healthcare setting in a cheap, scalable way.

    Abstract Lymphoma in the jaw bone is a rare malignant neoplasm with heterogeneous nature diagnosis of which requires utmost knowledge of cellular morphology and tissue architecture. The lineage of the neoplastic lymphocytes, whether it is B- or T-cell or mixed in nature, is designated by cluster of differentiation numbers. Broad classification of malignant lymphoma includes Hodgkin's and non-Hodgkin's lymphoma which have various subtypes. An unusual case of a B-cell lymphoma in the mandible in a middle-aged male patient is presented herewith clinicopathological and immunohistochemical features.
