Summary: The aim of this study was to investigate the influence of an agarose gel on the drug release kinetics of a PLGA implant. The presence of the gel was found to delay the onset of the second release phase of the drug, possibly due to the steric hindrance of implant swelling. These findings highlight the importance of PLGA swelling in controlling drug release.

Summary: This study explores the impact of Ca2+ on the electrochemical properties and performance of mung bean protein hydrogels loaded with catechin. The results indicate that increasing Ca2+ concentration significantly enhances the encapsulation efficiency and drug loading rates within the hydrogel, thereby improving drug delivery capabilities. Moreover, the electrochemical properties, such as viscosity and storage modulus (G'), of the hydrogel exhibit an optimal trend at a Ca2+ addition of 10%. Notably, the hydrogel demonstrates excellent slow-release properties in a simulated gastric-intestinal digestion model, especially with increased Ca2+ concentration. These findings emphasize the crucial role of Ca2+ in fine-tuning the electrochemical properties of mung bean protein hydrogels and offer valuable insights for the development of efficient drug delivery systems.

Summary: Food spoilage caused by foodborne microorganisms can lead to economic losses and pose a serious threat to human health through the toxins produced by some microorganisms. However, the application of essential oils (EOs) in food preservation is limited due to their volatility, insolubility in water, and sensitivity to light and heat. Therefore, this paper analyzes the antibacterial effect of EOs on foodborne bacteria and their mechanism, reviews the application strategies of EOs as sustained-release antimicrobial agents in food preservation, and analyzes the release mechanism and application cases of EOs in different antibacterial composites. The purpose is to provide technical support and solutions for the development of new antibacterial packaging materials based on plant active components to ensure food safety and reduce food waste.

Summary: The initiation of earthquakes remains a debated topic in earthquake science, with a gap between laboratory studies and real earthquake observations. The study shows that rupture nucleation phenomena observed on the lab scale can also be imaged on the microearthquake-scale, improving the quality of seismicity patterns and immediate foreshock phenomena. This approach may help bridge the observational gap between laboratory and field studies to enhance understanding of earthquake initiation mechanisms in the future.
