In tissue engineering, developing suitable printing inks for fabricating hydrogel scaffolds via 3D is of high importance and requires extensive investigation. Currently, gelatin methacryloyl (GelMA)-based have been widely used the construction 3D-printed cell-scaffold constructs human regeneration. However, many studies shown that GelMA at low polymer concentrations had poor printability, printed structures exhibited inadequate fidelity. current study, new viscoelastic composed (GelMA), sodium alginate (Alg), cellulose nanocrystal (CNC) were formulated investigated, with CNC being to improve printability fidelity Alg form ionically cross-linking networks enhance mechanical strength structures. Rheological results showed GelMA/Alg/CNC different Alg-to-CNC ratios possessed good shear-thinning behavior, indicating printing. The quantitative evaluation a concentration improved concurrently promoted hydrogels. On other hand, compression tests could hydrogels due increase in cross-link density. Furthermore, biocompatibility promote proliferation dental pulp stem cells (hDPSCs), suggesting their great potential engineering.

Electrospinning technology has demonstrated extensive applications in biomedical engineering, energy storage, and environmental remediation. However, its utilization the cosmetic industry remains relatively underexplored. To address challenges associated with skin damage caused by preservatives thickeners used for extending shelf life of conventional products, a soothing lavender-scented electrospun fibrous eye mask coaxial layers was developed using electrospinning technique. Polyvinyl alcohol (PVA) served as hydrophilic outer sheath, while polycaprolactone (PCL) constituted hydrophobic core, lavender oil (LO) encapsulated within. The structural physicochemical properties samples were characterized scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), contact angle measurements. Upon hydration, membrane exhibited strong adhesion properties, notable antioxidant activity, degree antibacterial efficacy, demonstrating potential safe effective use skincare applications. These findings suggest that material offers promising functional integration into formulations.

Summary: Perifolliculitis capitis abscedens et suffodiens (PCAS) is a chronic recurrent disease. Single treatment modalities are commonly ineffective. A surgical intervention combined with photodynamic therapy (PDT) may be an effective strategy. Herein, we present the case of 21-year-old man 2-month history PCAS treated such treatment. PDT directly eradicate sebaceous glands and reduce follicular hyperkeratosis, procedure can eliminate septic decayed tissue. The was in relieving patient’s pain, believe it provides option for PCAS.

Abstract Optic nerve regeneration remains challenging worldwide due to the limited intrinsic regenerative capacity of retinal ganglion cells (RGCs) and inhibitory microenvironment. Oxidative stress, induced by excessive reactive oxygen species (ROS) following optic injury, is associated with prolonged neuroinflammation, resulting in a secondary injury RGCs impairment axon regeneration. Herein, we developed bionic nanocomposite scaffold (GA@PDA) immunoregulatory ability for enhanced The ice-templating method was employed fabricate biopolymer-based scaffolds directional porous structure, mimicking nerve, which effectively guided oriented growth neuronal cells. incorporation bioinspired polydopamine nanoparticles (PDA NPs) further confers excellent ROS scavenging ability, thereby modulating phenotype transformation microglia/macrophages from pro-inflammatory M1 anti-inflammatory M2. In rat crush model, implantation GA@PDA survival promoted axonal Our study offers novel insights holds promising potential advancement engineered biomaterials facilitating
