Summary: The state of Campeche in Mexico is home to a significant green turtle rookery. After the practice of harvesting the turtles ceased, the population began to rebound. A study of the relationship between the number of nesting females and the number of hatchlings produced over a 37-year period revealed a correlation that could be influenced by environmental factors, such as the Atlantic Multidecadal Oscillation cycle.

Summary: There is limited information about sea turtle nesting distribution and seasonality in the Saudi Arabian Red Sea, which could negatively impact local populations. A 2019 survey showed that nesting was found at all surveyed sites in the central Red Sea, although emergence counts were often low. Nesting in previously undocumented sites favored the seaward side of islands, unlike previously documented areas. The substrate composition varied, with most sites being composed of calcium carbonate except for Ras Baridi, which had dark quartz-rich sediment. Future developments should avoid key nesting areas and consider the seaward bias in marginal rookeries where possible.

Summary: A case of disseminated mycobacteriosis caused by M. gordonae in a free-ranging sea turtle was reported in Rio de Janeiro, Brazil. The turtle exhibited granulomas and caseous exudate in multiple organs, and acid-fast bacteria were observed in various tissues. The source of the Mycobacterium remains unknown, but increased surveillance of mycobacterial species in wild sea turtles is crucial to understand their role as causative agents of infections.

Summary: By combining bioarchaeology with contemporary data, researchers have found that Mediterranean green turtles have been using the same North African seagrass meadows for at least 5,000 years, highlighting the significance of protecting these critical coastal habitats.

Summary: Cervical cancer is a major cause of female deaths, especially in low- and middle-income countries, and conventional treatment options for this complex disease are limited. In this study, copper oxide nanoparticles (CuONPs) were synthesized and modified for gene delivery, showing promising properties and efficient gene delivery in vitro. The biologically synthesized CuONPs were functionalized with chitosan and polyethylene glycol, and conjugated with folate for targeted gene therapy. The NPs demonstrated high cell viability and transgene expression in human embryonic kidney, breast adenocarcinoma, and cervical cancer cells.

Summary: Chelonian respiratory disease is challenging to diagnose and treat. This study reports a fatal case of respiratory disease in a green turtle caused by Serratia proteamaculans, a plant pathogen not previously known to cause disease in reptiles. The study highlights the importance of microbial culture in managing chelonian respiratory disease and considers the potential impact of phytopathogens in industrial or agricultural settings.

Summary: The study analyzed metal and metalloid concentrations in the liver tissue of green turtles stranded on the Brazilian coast, finding significant correlations between dietary shifts and element concentrations. Biological characteristics like age and sex also influenced element concentrations.

Summary: The study provides the first long-term offshore tracks of oceanic green turtles in the western North Atlantic waters, showing their preference for the Sargasso Sea and the use of thermally beneficial habitats. They also exhibit different orientation compared to loggerhead turtles of the same stage. The research suggests that oceanic-stage sea turtles may be more behaviorally complex than previously assumed.

Summary: Longline fishing vessels unintentionally catch endangered marine turtle species, such as green turtles, in the high seas. The stock composition of this bycatch is often complex and unknown, with individuals originating from different populations across the Pacific. To better understand the stock composition of green turtle bycatch, researchers collected 46 turtles caught by longline fishing vessels in the North- and South-central Pacific and used genetic analysis to determine their origins. The study found that turtle bycatch consisted of individuals from various breeding populations across the Pacific, suggesting overlapping geographic ranges during pelagic life stages.

Summary: The study characterized the gut microbiome of green sea turtles and their food items, finding Proteobacteria, Bacteroidetes, and Firmicutes as the most abundant bacterial phyla. Two red algae bacterial indicators were also identified in the cloacal compartments, suggesting the ingestion of microbial components that assist in digesting these food items.

Summary: This study reports the first case of severe trematode infection caused by Learedius learedi in a green sea turtle in the northern Red Sea, resulting in bilateral blindness. Necropsy revealed multiple granulomas with intralesional trematode eggs in various organs. Identification of the parasite was performed through specific primers of the ribosomal genome and COI sequences. These findings highlight the importance of recognizing the systemic nature of this fluke infection to protect the lives of marine animals and ensure species sustainability.

Summary: By monitoring the concentrations of sex hormones and blood chemistry in female green turtles, it is possible to predict their nesting activity. This study found significant changes in hormone levels and blood chemistry parameters in relation to nesting activity. These findings can help predict and prepare for nesting activities in green sea turtles, contributing to successful breeding programs.

Summary: Low-polarity fractions from sea-buckthorn exhibit strong cytotoxicity against cancer cells, potentially eliminating them through promoting apoptosis and moderate genotoxicity. Triterpenoids play a key role in this process.

Summary: This study used live cell imaging to observe the accumulation of amiodarone in primary rat alveolar type II cells, and found that it specifically accumulates in lamellar bodies. The uptake is rapid, while storage is persistent. The main mechanisms for intracellular bioaccumulation of amiodarone are proposed to be passive diffusion, ion-trapping, and lipophilic interactions.

Summary: m-Cresol is commonly used as an intermediate for pesticides and other industrial applications. This study investigated the hepatotoxicity of m-cresol using zebrafish larvae and explored its molecular mechanisms. The results suggest that m-cresol may induce liver damage in zebrafish larvae through oxidative stress and cell apoptosis pathways.
