Summary: The intake of fatty acids affects the composition of lipids in the body. In this study, rats were fed a peanut-oil-based diet for 33 days after weaning to investigate the effects of mild (n-3) deficiency on the lipid composition of various organs and feces. Results showed a lower level of docosahexaenoic acid (DHA) in the (n-3) deficient group compared to the control group, but no difference in DHA content was observed in the eyes and feces. This study highlights the importance of adequate maternal nutrition for a healthy fatty acid balance in rats.

Summary: This study aimed to investigate the relationship between fatty acid (FA) and polar lipid species composition in human milk. The results showed that there were no differences in major FA, phosphatidylcholine, or sphingomyelin species percentages between milk with high or low fat content. However, milk with high fat content had lower ratios of phospholipid-to-total-FA and sphingomyelin-to-phosphatidylcholine compared to milk with low fat content.

Summary: The increase in fetal requirements of long-chain polyunsaturated fatty acids during pregnancy alters maternal fatty acid metabolism, and FADS gene polymorphisms may change blood fatty acid composition differently. The study investigated the relationship between a FADS1 SNP and maternal serum LCPUFA levels in Japanese pregnant women. The results showed that LCPUFAs significantly decreased as pregnancy progressed and certain fatty acids were significantly associated with the number of minor FADS1 SNP alleles, indicating genotype effects become more obvious later in pregnancy.

Summary: This study examined the composition and contents of fatty acids (FA) in fillets of seven strains of rainbow trout. The results showed that the diet composition and genetics played a role in the FA composition of the fish. The Steelhead strain of rainbow trout demonstrated a higher ability to regulate its FA composition, particularly regarding the important acids EPA and DHA. Furthermore, FA markers were identified that can be used to differentiate between wild and farmed rainbow trout.

Summary: This study isolated fast-growing thraustochytrids from mangrove habitat and investigated the influence of seasonal variation on their fatty acid composition. The presence of high DHA-producing thraustochytrids in lower temperature seasons was confirmed, highlighting the importance of environmental temperature conditions and fatty acid composition as a dietary biomarker. Additionally, the ecological significance of thraustochytrids in DHA enrichment in the marine food web was revealed.

Summary: This study investigated the role of dietary docosahexaenoic acid (DHA) in improving liver health in Nile tilapia. The results showed that tilapia fed on DHA diets had lower lipid content in the liver and serum, as well as decreased triglyceride concentrations. Furthermore, DHA supplementation also downregulated the expression of genes related to liver damage.

Summary: This study analyzed the intake of polyunsaturated fatty acids (PUFAs) during complementary feeding (CF) in very low birth weight (VLBW) infants and its impact on neurodevelopment. The results showed that higher intake of total PUFAs, docosahexaenoic acid (DHA), and arachidonic acid (AA) was associated with improved cognitive and motor function at 12 months of age. However, the dietary intake of AA and DHA did not meet the recommended levels, highlighting the need to increase PUFA, DHA, and AA intake during CF for better neurodevelopmental outcomes in VLBW infants.

Summary: This study aims to estimate the amount of n-3 LC-PUFA provided by commonly consumed fishes, shrimps, and mollusks, to conduct a risk-benefit analysis of fish consumption. Consuming 2-3 servings of a variety of fishery products per week can help meet recommended n-3 LC-PUFA levels while maintaining a balance to avoid potential risks from contaminants.

Summary: Microplastics are found everywhere in the world's oceans and their potential toxic effects on aquatic ecosystems remain unknown. This study evaluated biochemical responses caused by fluorescent red polymer microspheres (FRM) on nauplii and juveniles of Artemia franciscana, revealing that juveniles showed decreased survival after exposure to higher concentrations of FRM, potentially indicating neurotoxic and oxidative damage effects induced by the microplastics. The research highlights the need to understand the mechanisms of microplastics toxicity and their impacts on environmental safety.

Summary: The study found that only a few genes are consistently associated with asexual evolution, suggesting that extensive restructuring of the meiotic machinery may not be necessary. Sex-biased genes in Eurasian Artemia have high rates of expression divergence, but do not show unusual evolutionary patterns after the loss of sexuality.

Summary: This study provides a detailed characterization of sex chromosomes and asexual transmission in Eurasian brine shrimp. The researchers identified a small differentiated region of sex chromosomes that is shared by all sexual and asexual lineages, supporting the shared ancestry of these chromosomes. It was also found that recombination suppression has independently spread to larger sections of the chromosome in the American and Eurasian lineages. Additionally, the study suggests that parthenogenesis in these shrimp is partly controlled by a locus on the Z chromosome, highlighting the interplay between sex determination and asexuality.

Summary: Long-chain (>= C-20) polyunsaturated fatty acids (LC-PUFAs) are physiologically important for most animals, including humans. Recent research indicates the ability of certain invertebrates, mainly marine organisms, to synthesize and convert LC-PUFAs. The genetic pathways and mechanisms of LC-PUFA biosynthesis remain unknown in many invertebrates, but existing genomic resources can contribute to our understanding. This study identified key enzymes responsible for LC-PUFA biosynthesis in the copepod Platychelipus littoralis and demonstrated their functionality using heterologous expression in yeast.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
