A facile combined therapy of chemotherapeutic agent and microRNA for hepatocellular carcinoma using non-cationic nanogel.

High drug resistance remains a challenge for chemotherapy against hepatocellular carcinoma (HCC). Combining chemotherapeutic agents with microRNA (miRNA), which simultaneously regulates multiple pathways, offers a promising approach to improve therapeutic efficacy against HCC. Although cationic amphiphilic copolymers have been used to co-deliver these agents, their effectiveness is often limited by low co-encapsulation efficiency and inherent cationic toxicity.

Bone marrow mesenchymal stem cells promote uterine healing by activating the PI3K/AKT pathway and modulating inflammation in rat models.

Background: Uterine injury can cause uterine scarring, leading to a series of complications that threaten women's health. Uterine healing is a complex process, and there are currently no effective treatments. Although our previous studies have shown that bone marrow mesenchymal stem cells (BMSCs) promote uterine damage repair, the underlying mechanisms remain unclear.

A OHCs-Targeted Strategy for PEDF Delivery in Noise-Induced Hearing Loss.

Noise-induced hearing loss (NIHL) results from prolonged exposure to intense noise, causing damage to sensory outer hair cells (OHCs) and spiral ganglion neurons (SGNs).

ESO-Based Non-Singular Terminal Filtered Integral Sliding Mode Backstepping Control for Unmanned Surface Vessels.

Aiming at the control challenges faced by unmanned surface vessels (USVs) in complex environments, such as nonlinearities, parameter uncertainties, and environmental perturbations, we propose a non-singular terminal integral sliding mode control strategy based on an extended state observer (ESO). The strategy first employs a third-order linear extended state observer to estimate the total disturbances of the USV system, encompassing both external disturbances and internal nonlinearities. Subsequently, a backstepping sliding mode controller based on the Lyapunov theory is designed to generate the steering torque control commands for the USV.
