Summary: We report the design of photo- and electroactivated hydrogels that can capture and deliver cargo, avoid obstacles, and return without external, stepwise control. By incorporating two spiropyran monomers with different chemical substituents in the hydrogel, we created chemically random networks that enabled photoregulated charge reversal and autonomous behaviors under a constant electric field. The hydrogel can also autonomously bypass low dielectric constant materials and be attracted to high dielectric constant materials under the guidance of the electric field vector induced by a dielectric inhomogeneity.

Summary: The design of antioxidant and electroconductive Alg-PPy/PLL hydrogels for treating neurodegenerative disorders is discussed. These hydrogels showed great potential for enhancing healing efficiencies due to their antioxidant effects and versatile features. The introduction of PPy enhanced the antioxidant activity of the hydrogels, while PLL provided excellent stem cell differentiation ability. Furthermore, the morphology, porosity, antioxidant activity, rheological behavior, and conductive characteristics of the hydrogels could be precisely adjusted by altering the amount of PPy.

Summary: This study investigated the relationship between the number of coils in an mTMS transducer, the focality of the induced E-field, and the extent of the cortical region within which the location and orientation of the maximum of the induced E-field can be controlled. The results showed that sacrificing E-field focality could lead to designing an mTMS transducer that can control the location and orientation of the peak of the induced E-field within a wider cortical region. This may simplify the electronically targeted TMS and accelerate the development of new clinical and research applications in the field.

Summary: Waste PET plastics were utilized to create Ag3PO4/UiO-66-NH2@PET (PAU-X) for the adsorption and light-responsive desorption of SMX. PAU-X can capture SMX in the absence of light and release it under visible light. The breaking of the Ag-N bond between Ag3PO4 and SMX is the main mechanism for the desorption process.

Summary: Solid-state lithium batteries with solid polymer electrolytes have received extensive attention due to their potential in high energy density and safety. However, the limited ionic conductivities of the electrolytes and their low tolerance to high-voltage cathodes have hindered their practical applications. In this study, a polymer-in-salt solid electrolyte (PGPE) with superior electrochemical properties is developed for high-voltage lithium batteries operated at room temperature. The PGPE exhibits high ionic conductivity, excellent electrochemical stability, and superior interfacial stability, leading to a solid-state battery with high discharge capacity and long-term cycling stability.

Summary: In this study, a smart titanium surface was developed by incorporating a thermoresponsive polymer and antimicrobial peptide. This surface was able to adapt to different stages of implantation, including surgical implantation, normal physiological stage, and bacterial infection stage. The optimized surface inhibited bacterial adhesion and biofilm formation during surgical implantation and promoted osteogenesis in the physiological stage. In the bacterial infection stage, the temperature increase induced polymer chain collapse, exposing antimicrobial peptides to protect adhered cells from the hostile environment of infection. The engineered surface demonstrated its ability to inhibit infection and promote tissue healing in experimental models.

Summary: This research investigates the occurrence, mechanism, diagnosis, treatment, and subsequent endocrine therapy of severe pancreatitis induced by tamoxifen treatment in patients who have undergone breast cancer surgery. Two cases of severe acute pancreatitis after tamoxifen therapy were studied, and a literature review was provided. Both cases involved severe hyperlipidemic pancreatitis, but none died after conservative treatment and switching endocrine therapy drugs. Endocrine therapy with tamoxifen in breast cancer patients can induce hyperlipidemia, leading to severe pancreatitis. The treatment of severe pancreatitis should focus on blood lipid regulation and involve various treatments to promote recovery and reduce serious complications. Patients with severe pancreatitis should avoid using tamoxifen for endocrine therapy, considering switching to a steroidal aromatase inhibitor for follow-up therapy if possible.
