Biological Function of Medium-Chain Fatty Acids and Their Application in Aquatic Animals: A Review.

Medium-chain fatty acid triglycerides (MCTs) possess antibacterial, antiviral, nutritional, and other biological activities and have demonstrated significant application potential in humans and terrestrial animals. In recent years, with the development of the green aquaculture industry, MCTs have been gradually applied to aquaculture animals, which can enhance growth performance, improve flesh quality, regulate lipid metabolism, boost immune activity, and modulate the intestinal flora, thereby improving the production efficiency of aquaculture. This paper elaborates in detail on the biological activities of MCTs and their applications in aquatic animals, providing a theoretical and practical basis for the application of MCTs in aquaculture.

Transcriptomic analysis of the effect of dietary melatonin on liver immunity in rice field eel (Monopterus albus).

The aim of this study was to investigate the effects of the dietary effects of melatonin, particularly in relation to its ability to regulate the immune system.

Microbial Life History Mediates the Drought-Induced Decrease in Wood Decomposition in Subtropical Forests.

Progressive intensification of drought regimes worldwide threatens wood decomposition - a critical biogeochemical process in forest carbon cycling. However, the interactions between microbial strategies, wood traits and microclimate in regulating wood decomposition remain poorly understood under drought conditions. In a throughfall exclusion experiment (control 35% and 70% rainfall reduction) across 12 tree species, we found that drought-induced reductions in wood CO efflux rates were primarily driven by wood traits (density and carbon reduction) and shifts in fungal K/r-strategies.

Long-term rice-eel co-culture system effectively alleviated the accumulation of antibiotic resistance genes in soil.

Alleviating the accumulation of antibiotic resistance genes (ARGs) in farmlands is crucial for restricting the transfer of ARGs to crops and controlling the soil-borne microbiological health risk. Rice and eel co-culture (REC) systems have recently been used as an emerging integrated farming model that can stabilize grain yields and improve fertilizer availability. However, the influence of long-term REC system concerning the aggregation and health risk of ARGs in rice fields is still unclear.
