Summary: Fibrosis of the filtering bleb is a common cause of failure in bleb-forming glaucoma surgery. This study investigates the use of a sustained-release drug delivery system (DDS) loaded with mitomycin C (MMC) to reduce fibrosis. Two different MMC-loaded DDSs are tested and compared to a control group. The results show that both DDSs release a significant amount of MMC and maintain functioning blebs, but the PLGA DDS exhibits less inflammation and more complete degradation compared to the PCL DDS.

Summary: This study fabricates protein-based soft actuators with magnetic responsiveness using naturally occurring silk proteins and synthesized Fe3O4 magnetic nanoparticles. The results show that the soft actuators have good stretchability, mechanical properties matching soft tissues, degradability, biocompatibility, and in vivo X-ray visibility. The soft actuators can be actuated and used for localized drug delivery by attaching a magnet. These degradable silk-based soft actuators provide significant opportunities for improving current therapeutic strategies in biomedicine.

Summary: By modifying polyethylene glycol (PEG) with 1,2,4-triazoline-3,5-diones (TAD) under green light, we achieved both functionality and degradability of the PEG backbone. The TAD-PEG conjugates are degradable in aqueous medium under physiological conditions, with degradation rate depending on pH and temperature. Using TAD-derivatized PEG-lipid, we successfully improved messenger RNA (mRNA) transfection efficiency in vitro, and observed a similar tissue distribution in mice in vivo. These findings open up possibilities for the design of degradable, backbone-functionalized PEG in nanomedicine and beyond.

Summary: This study utilized computational and 3D models to investigate antibiotic drug transport from a hydrogel drug delivery system to the eye. Different routes of drug administration showed varying times to reach peak concentrations in the vitreous, but all successfully achieved therapeutic levels. These models could potentially be used to optimize drug loading doses in the delivery system to minimize drug use and waste.

Summary: The gene encoding SPOP is frequently mutated in prostate cancer (PCa). This study reveals that SPOP functions as a tumor suppressor by degrading PrLZ, a prostate-specific and androgen-responsive gene. ERK1/2 regulates SPOP-mediated PrLZ degradation through phosphorylation, while IL-6 acts as an upstream regulator of PrLZ degradation by promoting its phosphorylation.

Summary: This study investigates the educational planning and changes in teachers' beliefs and practices during the COVID-19 pandemic in science and technology universities. The findings show that educational planning and policies have helped teachers adapt to new demands and changes, and there is generally alignment between teachers' beliefs and practices and the educational planning. However, tensions still exist. The discussion focuses on emergency remote teaching and planning, tensions between teacher beliefs and practices, and the transition from emergency remote teaching to regular, sustainable online schooling.

Summary: A physical model-based tool wear and breakage monitoring method is proposed in this paper. The comprehensive feature is extracted from the seven-channel specific cutting force coefficients (SCFCs) through the measurements of milling force, spindle box vibration and driving current for tool wear monitoring. An efficient tool breakage monitoring method is also put forward. The verification results indicate that the proposed method can accurately estimate the cutting status of the tool and provide a research basis for the potential industrial application of tool wear and breakage monitoring technology.

Summary: UN's 2030 Agenda for Sustainable Development emphasizes the important role of education in securing a promising future in today's digital era. However, the prevalence of smartphones has led to increased digital multitasking among students, posing a significant threat to education, especially in higher education. This study surveyed 519 students from a university in China to investigate the extent of digital multitasking, motivations behind it, and beliefs about reducing phone use. The findings suggest that although students express a desire to reduce digital multitasking, they are hesitant to follow strict rules on phone use. There is also no clear consensus on whether schools should implement more restrictions.

Summary: This paper introduces a tunable quasi-zero stiffness mechanism for a MEMS gravimeter, utilizing a combination of pre-shaped bistable beam and conventional folded springs. V-beam actuators are employed for stiffness compensation. The system's behavior is theoretically modeled using the Galerkin method, demonstrating potential for a highly stable gravimeter through active tuning of negative stiffness values and intervals.
