Summary: In this study, the effects of the phytoestrogens genistein and daidzein on sex differentiation and sex-specific genes in Japanese eels were examined. Genistein was found to induce feminization more efficiently than daidzein, by altering the molecular pathways responsible for eel sex differentiation.

Summary: This study examined the annual occurrence patterns of Japanese glass eels in the Pearl River estuary from 2011 to 2022. The most frequently occurring Japanese glass eels had a total length of 5.3 cm. The collection season extended from December to February, with a significant decrease in catch-per-unit-effort over the years. The study also found that tidal range, water temperature, and lunar distance significantly affected the daily changes in Japanese glass eel collection.

Summary: The study found that Anguilla japonica glass eels from southern Japan show strong preferences for fresh water and agricultural water, with water temperature influencing their locomotor activity and preference for fresh water. The attraction to agricultural water suggests a potential impact on their upstream migration and habitat selection.

Summary: The larvae of Japanese eel travel a long distance through the North Equatorial Current and the Kuroshio, and the spawning behavior of mature eels results in monthly arrival waves in eastern Taiwan. Recent research has shown that the total length of glass eels can indicate their larval duration and age. Analyzing the monthly mean lengths of eels in eastern Taiwan from 2010 to 2021, it was found that the early recruits had significantly larger total lengths than the late recruits. The recruitment lag between Taiwan and Japan was about 1-1.5 months, with higher abundance of early recruits in Taiwan and late recruits in Japan. The study suggests that the main streams of the North Equatorial Current and the Kuroshio, as well as their monthly velocity changes, could influence the distribution patterns of Japanese glass eels in Taiwan and Japan.

Summary: The distribution of Japanese eels was investigated using environmental DNA (eDNA) monitoring, revealing high eDNA concentrations in rivers on the Pacific side and lower concentrations on the Sea of Japan side. The study suggests that the distribution of Japanese eels is mainly determined by maritime larval transport, with their survival and growth dependent on food abundance in rivers.

Summary: New Caledonia is heavily impacted by nickel open pit mining activities due to the presence of ultramafic soils rich in metals. The dispersion of particles during the excavation process results in deposition or leaching in rivers, leading to bioaccumulation in downstream organisms. This study investigates the bioaccumulation of metals in eels and its potential effects on their health.

Summary: Postfracture treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) may delay healing, whereas this study found that flunixin meglumine (FM) enhanced bone fracture healing in rabbits by promoting early collagen deposition, angiogenesis, and vascular endothelial growth factor expression. In contrast, ketoprofen was found to delay bone fracture healing. This study suggests that FM may have beneficial effects on bone fracture healing, providing new insights into potential treatment options.

Summary: Cancer is the second leading cause of death worldwide, and current treatment options are often uncomfortable and ineffective. Plant-derived natural chemicals, such as flavonoids, have gained attention due to their high bioavailability, safety, few side effects, and cost-effectiveness. Flavonoids have shown promising cytotoxic anti-cancer effects and are being researched for their ability to target inflammation and apoptosis. In a laboratory study, genistin, a flavonoid compound, demonstrated good cytotoxic activity against breast cancer cell lines. In vivo studies on animals also showed that genistin reduced tumor weight, volume, and certain biochemical markers associated with cancer progression.
