Summary: This study evaluates the long-term survival of Atlantic salmon that were caught and released as compared to a control group. The results suggest that catch and release can be an effective management tool, with high survival rates at cool to moderate water temperatures.

Summary: The individual actions and perspectives of anglers play a significant role in the success or failure of fisheries management tools, such as catch-and-release. This study conducted a survey of 94 sea trout anglers in a predominantly catch-and-release fishery, investigating their motivations to release or retain catches, self-assessment of their own ability to release fish, and their rating of various factors influencing the success of catch-and-release. The study found that anglers were primarily motivated to retain catches when they believed the fish were unlikely to survive, while the spawning status of individual fish was the main motivation for release. Factors such as water temperature, hook type, and barbless hooks were rated as less important. Anglers who rated their ability to release sea trout favorably also placed greater importance on factors influencing the success of release, reported higher catch rates, and released a higher proportion of their catches.

Summary: Synthetic textiles are a major source of microplastic fibers, with weathering being identified as a contributing process to their formation and presence in the environment. UV-light-induced artificial weathering of polyester fabrics resulted in the formation of microplastic fibers matching the size of the fibers in the textiles, as well as other shapes of microplastic fibers. The quantity of released microplastics significantly increased with weathering, with weathered fabrics potentially being 20-40 times larger sources of microplastic fibers compared to washing studies.

Summary: This study investigated the release of carbon nanotubes (CNTs) from CNT epoxy nanocomposites under environmental weathering and mechanical stresses. The results showed continuous release of CNTs during the weathering process, and additional mechanical stresses resulted in further release of CNTs.

Summary: The study found that exposure to pollutants during pregnancy and after birth has an impact on children's doctor diagnosed pneumonia (DDP). Intrauterine and post-natal exposure to PM2.5, PM2.5-10, and PM10 were associated with DDP. Intrauterine exposure to PM2.5 and post-natal exposure to PM10 were associated with increased risk of pneumonia. The second trimester, third trimester, and first year after birth were identified as critical windows for PM2.5, PM2.5-10, and PM10 exposure. Daytime exposure to traffic-related pollution, especially in early life, increased the risk of DDP.

Summary: The research shows that vesicular release in pancreatic beta cells is not all-or-none, but rather partial release of insulin and serotonin. Utilizing nanoscale amperometric chemical methods, the study quantified the amount of serotonin stored and released during each exocytosis event, revealing that beta cells only release one-third of their granule content. This has implications for understanding type-2 diabetes.

Summary: The study reveals that the wetter margins in the climate are likely limited by biotic interactions in the native range. During naturalization, species tend to expand into wetter climate conditions and are less likely to colonize the hottest or coldest portions of their potential niche.

Summary: Genetic individual assignment of river stock of origin of mixed stock catch fish offers a tool to analyze size differences among river stocks. The study found significant differences in sizes of mature Atlantic salmon catch fish from different rivers, and the Bayesian mixture model yielded slightly more conservative estimates for the final mean length distributions of the stocks compared to other methods.

Summary: Overexploitation is causing depletion of Mediterranean trout populations. Total Catch and Release (C&R) management can reduce catch-related impacts, but it cannot fully replace stricter criteria. The study found that C&R areas had higher trout abundance and balanced age structures compared to exploited areas, but still lower than no-fishing areas. Intensive size-selective harvest in fishing areas negatively affected population structure, especially for older fish.

Summary: Disinfecting swimming pool water is crucial for preventing waterborne diseases, although it can lead to the formation of disinfection by-products (DBPs), which can have harmful health effects. This study focuses on the reaction between chlorine and particles released by bathers in swimming pools. Filtered and unfiltered backwash waters from multiple swimming pools were collected and analyzed, and their reactions with varying concentrations of chlorine were examined. The results showed that a significant amount of DBPs, such as chloroform, haloacetic acids (HAAs), and haloacetonitriles (HANs), were generated during the chlorination process, with approximately 50% of them being derived from particles brought by bathers.

Summary: The study investigated the impacts of hypoxia during short-time transportation on the muscle quality of rainbow trout and its relief attempt by reoxygenation. The results showed that severe hypoxic trout exhibited lower shearing force, saturated fatty acid content, and delicious amino acids, and higher expressible moisture, Metmyoglobin, and essential amino acids content compared to the sample without hypoxia. Reoxygenation for 24 h effectively relieved the quality deterioration of rainbow trout fillets induced by hypoxia.

Summary: A new method combining electrophysiology and electrochemistry was developed to precisely measure the intact quantal neurotransmitter content of single vesicles. By using a glass pipette and an etched submicro-carbon fiber electrode, intact quantal release at dopaminergic varicosities was successfully detected in real time with minimal leakage.

Summary: Exposure to PM2.5 between the 7th and the 14st gestational weeks was significantly associated with preeclampsia among Jewish women, while no such association was observed for Bedouin women. Cumulative exposure to PM2.5 during the first 25th gestational weeks was also significantly linked to preeclampsia among Jewish women.

Summary: The study found that the behavior of Hg release from iron ores during temperature-programmed heat treatment (TPHT) in air depends significantly on the type of ore, including the evolved forms and forms that remain thermally stable. Experiments on model Hg compounds suggest the presence of several types of Hg forms in the considered iron ores. These findings provide insights for designing an efficient method for the removal of Hg from iron ore and gaseous Hg.
