Handcrafted Silicone Coated Filament for Mice Middle Cerebral Artery Occlusion Models.

As the global population ages, ischemic stroke has risen to become the second leading cause of disability and mortality worldwide, placing an immense burden on both society and families. Although treatments such as intravenous thrombolysis and endovascular interventions can substantially improve the outcomes for patients with acute ischemic stroke, only a small percentage of individuals benefit from these therapies. To advance our understanding of the disease and to discover more effective treatments, researchers are continuously developing and refining animal models.

Systemic Tumor Suppression via Macrophage-Driven Automated Homing of Metal-Phenolic-Gated Nanosponges for Metastatic Melanoma.

Cell-based therapies comprising the administration of living cells to patients for direct therapeutic activities have experienced remarkable success in the clinic, of which macrophages hold great potential for targeted drug delivery due to their inherent chemotactic mobility and homing ability to tumors with high efficiency. However, such targeted delivery of drugs through cellular systems remains a significant challenge due to the complexity of balancing high drug-loading with high accumulations in solid tumors. Herein, a tumor-targeting cellular drug delivery system (MAGN) by surface engineering of tumor-homing macrophages (Mφs) with biologically responsive nanosponges is reported.

Controlling burst and final drug release times from porous polylactide devices derived from co-continuous polymer blends.

This work has demonstrated that it is possible to exercise a wide range of control over both the initial burst release and the final drug release times from porous polylactide (PLA) devices derived from cocontinuous polymer blends. Two strategies were used: a layer-by-layer polyelectrolyte surface deposition approach on the porous PLA surface and the application of a partially closed-cell protocol. A PLA porous substrate with a pore size of 1.
