AI Article Synopsis
- * The nanoconstruct, made from copper sulfide (CuS), graphene oxide (GO), and doxorubicin (DOX), shows responsive drug release and improved photothermal activity for combined chemo-phototherapy.
- * In vivo studies indicate that the nanoconstruct accumulates effectively in tumors, leading to significant tumor growth inhibition and altered levels of key biological markers related to cancer progression, highlighting its promise for future clinical applications.
Article Abstract
Hyaluronic acid (HA) assisted effective internalization into CD44 receptor-overexpressing cancer cells, which could offer an excellent cytotoxic profile and tumor alterations. In this study, duo-photothermal agents (copper sulfide (CuS) and graphene oxide (GO)), chemotherapeutic drug (doxorubicin (DOX)), and targeting moiety (HA) were incorporated into a complexed nanoconstruct for trio-responsive chemo-phototherapy. The nanosystem (CuS(DOX)-GO-HA) was demonstrating its responsive drug release and escalated photothermal behavior. The hyperthermia and photodynamic effect were observed along with efficient ROS generation in the presence of dual photosensitizers. The in vivo biodistribution and photothermal profile reflected a high accumulation and retention of the nanoconstruct in the tumor. Importantly, nanoconstructs effectively inhibit tumor growth based on tumor volume analysis and the altered expression of apoptosis, cell proliferation, and angiogenesis markers. Collectively, these findings suggest that this nanoconstruct has excellent antitumor effects in CD44 overexpressed cells showing the potential for clinical translation in the future.

Inadequate vascularization significantly hampers wound recovery by limiting nutrient delivery. To address this challenge, we extracted membrane vesicles from (LMVs) and identified their angiogenic potential via transcriptomic analysis. We further developed a composite hydrogel system (Gel-LMVs) by anchoring LMVs within carboxylated chitosan and cross-linking it with oxidized hyaluronic acid through a Schiff base reaction.

Multidrug resistance (MDR) facilitates tumor recurrence and metastasis, which has become a main cause of chemotherapy failure in clinical. However, the current therapeutic effects against MDR remain unsatisfactory, mainly hampered by the rigid structure of drug-resistant cell membranes and the uncontrolled drug release. In this study, based on a sequential drug release strategy, we engineered a core-shell nanoparticle (DOX-M@CaP@ATV@HA) depleting cholesterol for reverse tumor MDR.

Background: Hyaluronic acid (HA) fillers are commonly used in esthetic medicine for facial contouring and rejuvenation. However, complications such as overcorrection, vascular occlusion, and irregular filler distribution necessitate the use of hyaluronidase to dissolve the fillers. This study aimed to evaluate the efficacy of hyaluronidase in degrading different types of HA fillers and provide clinical guidelines for its use based on filler type, dosage, and application techniques.

Uncontrollable non-compressible hemorrhage and traumatic infection have been major causes of mortality and disability in both civilian and military populations. A dressing designed for point-of-care control of non-compressible hemorrhage and prevention of traumatic infections represents an urgent medical need. Here, a novel self-gelling sponge OHN@ε-pL is developed, integrating N-succinimidyl ester oxidized hyaluronic acid (OHN) and ε-poly-L-lysine (ε-pL).
