To monitor the biological effects of marine pollution, choosing a native fish species and establishing suitable biomarkers are required. In this study, the full-length cDNA of cyp1a1 was cloned from Sebastiscus marmoratus (SM-CYP1A1). Then the dose-response and time-course induction of hepatic CYP1A1 mRNA by the crude oil water-soluble fraction (WSF) were determined. Subsequently, SM-CYP1A1 mRNA was applied to investigate the biological effect of petroleum hydrocarbon pollution in Quanzhou Bay, China. The transcription levels of hepatic CYP1A1 were significantly elevated in fish caged in the polluted sites for 2weeks compared with those of the reference site, which were correlated with the concentrations of petroleum hydrocarbon and polycyclic aromatic hydrocarbon (PAH) in the surface seawaters...

BACKGROUND: Docosahexaenoic acid (DHA) is a major dietary n-3 polyunsaturated fatty acid (n-3 PUFA) in fish oil, and has been reported to possess a number of biological properties, such as anti-inflammatory, antitumor and immune-regulatory properties. However, whether DHA exert anti-inflammatory effect on lipopolysaccharide (LPS)-induced mastitis remains unclear. In this study, we investigate the effect and underlying mechanisms of the effects of DHA on LPS-stimulated primary bovine mammary epithelial cells (bMEC)...

Rabbitfish Siganus canaliculatus is the first marine teleost reported to have the ability of biosynthesizing C20-22 long-chain polyunsaturated fatty acids (LC-PUFA) from C18 precursors, and thus provides us a model for studying the regulatory mechanisms of LC-PUFA biosynthesis in teleosts. To investigate the possible roles of peroxisome proliferator-activated receptors (PPARs), critical transcription factors involved in the regulation of lipid metabolism, in the regulation of LC-PUFA biosynthesis in rabbitfish, the PPAR genes were cloned and their expression characterization with PPAR agonists, dietary lipid resource, and ambient salinity were examined...

This study examines how local residents make sense of offshore oil production risks in Ghana's nascent petroleum industry. From a naturalistic-interpretive perspective, it is primarily based on in-depth interviews with community residents: 8 opinion leaders, 15 residents, and 1 journalist. Residents associate Tullow's oil activities with health concerns (e.g. conjunctivitis), environmental challenges (e.g. the emergence of decomposed seaweeds along the shore), and socio-economic concerns (e.g. loss of livelihoods, decline in fish harvest, and increased rent and cost of living)...

Docosahexaenoic acid (DHA), an omega-3 polyunsaturated fatty acid present in fish oil, has been described as a promising molecule to the treatment of Helicobacter pylori gastric infection. However, due to its highly unsaturated structure, DHA can be easily oxidized loosing part of its bioactivity. This work aims the nanoencapsulation of DHA to improve its bactericidal efficacy against H. pylori. DHA was loaded into nanostructured lipid carriers (NLC) produced by hot homogenization and ultrasonication using a blend of lipids (Precirol ATO5(®), Miglyol-812(®)) and a surfactant (Tween 60(®))...

BACKGROUND & AIMS: Intravenous lipid emulsions (IVLEs) are a key component in long-term home parenteral nutrition (HPN), providing energy and essential fatty acids (EFAs). Modification of the fatty acid (FA) composition of IVLEs may lead to changes in metabolic responses and cell and tissue function, providing opportunity for clinical improvements. Studies have suggested that, in place of conventional pure soybean oil (SO)-based IVLEs, which have a high omega-6 FA content, alternative IVLEs with different FA profiles may have beneficial effects...
