Summary: Seaports are crucial for connecting inland and maritime transportation, and tugboats play a vital role in providing enough power and ensuring safety for container ships when entering and leaving seaports. Thus, scheduling tugboats in seaport management is essential to facilitate the cost-effective movement of container ships. This paper investigates the tugboat scheduling problem considering multiple services at multiple waypoints to optimize the utilization of limited tugboats. An efficient adaptive large neighborhood search algorithm with a feasibility check procedure is proposed and validated through computational experiments, providing valuable managerial insights based on sensitivity analysis.

Summary: In the field of international maritime transport, the phenomenon of naval gigantism has emerged with the advent of ever larger ships. These giant vessels face operational issues due to their large draft, such as restrictions in accessing small ports and determining the optimal sequence of port visits. Additionally, draft restrictions also impact the fleet sizing problem, although large ships offer lower travel costs per load unit due to economies of scale.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
