Brain-targeting redox-sensitive micelles for codelivery of TMZ and β-lapachone for glioblastoma therapy.

Glioblastoma (GBM) is a central nervous system cancer with high incidence and poor survival rates. Enhancing drug penetration of the blood-brain barrier (BBB) and targeting efficacy is crucial for improving treatment outcomes. In this study, we developed a redox-sensitive targeted nano-delivery system (HCA-A2) for temozolomide (TMZ) and β-lapachone (β-Lapa).

Preparation of methacrylated hyaluronate/methacrylated collagen sponges with rapid shape recovery and orderly channel for fast blood absorption as hemostatic dressing.

Uncontrolled hemorrhage of deep, narrow, and non-compressible perforating wounds is responsible for many trauma deaths. In this study, a rapid hemostatic sponge with an orderly channel based on methacrylated collagen (ColMA) was prepared via directional freeze-drying technology. The methacrylated hyaluronate (HAMA) was added to further enhance the mechanical properties of the sponge.
