Microalgae are the primary producers of omega-3 LC-PUFA, which are known for their health benefits. Their oil may thus be a potential alternative for fish oil. However, oxidative and hydrolytic stability of omega-3 LC-PUFA oils are important parameters. The purpose of this work was therefore to evaluate these parameters in oils from photoautotrophic microalgae (Isochrysis, Phaeodactylum, Nannochloropsis gaditana, and Nannochloropsis sp.) obtained with hexane/isopropanol (HI) and hexane (H) and compare them with commercial omega-3 LC-PUFA oils. When the results of both the primary and secondary oxidation parameters were put together, it was clear that fish, tuna, and heterotrophic microalgae oil are the least oxidatively stable oils, whereas krill oil and the microalgae oils performed better. The microalgal HI oils were shown to be more oxidatively stable than the microalgal H oils. The hydrolytic stability was shown not to be a problem during the storage of any of the oils.

Omega-3 LC-PUFA consumption is now recommended for women of childbearing age and during pregnancy to protect against preterm and early preterm birth: implementing this recommendation in a sustainable manner.

Preterm birth (delivery prior to 37 weeks) appears to be rising globally, increasing the risk of a myriad of down-stream disorders which affect families, their offspring and society, including increased morbidity, mortality and economic costs. Strategies for prevention of preterm birth have therefore become a priority among healthcare providers. One proposed strategy is increased consumption of Omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs), particularly docosahexaenoic acid (DHA) (from food or supplements) in women of childbearing age and during pregnancy.

Article Synopsis
- * This study analyzed eight randomized controlled trials to determine the effects of omega-3 LC-PUFAs on sleep, finding that sleep efficiency was better in the omega-3 group, even though sleep latency and total sleep duration didn't show significant changes.
- * Subjective assessments indicated that omega-3 LC-PUFAs improved perceived sleep quality, prompting further research to confirm these findings and better understand the dosage effects.

Long-chain polyunsaturated fatty acids (LC-PUFA) like arachidonic acid (ARA, 20:4n-6), eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3) constitute one-third to half of fish sperm lipids. Fish sperm is rich in phospholipid (PL)-primarily phosphatidylcholine, phosphatidylethanolamine, and sphingomyelin. DHA is generally the most abundant LC-PUFA in each PL class, followed by competition between ARA and EPA.

Article Synopsis
- Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFA) from aquatic products enhance meat quality and human health, with marine fish sourcing these acids differently than freshwater fish, which primarily use linolenic acid (ALA) from their diet to synthesize n-3 LC-PUFAs.
- The research involved assessing the effects of various diets (low and high-fat rapeseed oil and transgenic rapeseed oil) on the growth and health of juvenile largemouth bass, revealing no major differences in survival or weight gain between the diet groups.
- The study found that TRO diets significantly boosted n-3 LC-PUFA levels, reduced liver and

Searching for positive selection signals across genomes has identified functional genetic variants responding to environmental change. In Native Americans of Mexico, we used the fixation index (F) and population branch statistic (PBS) to identify SNPs suggesting positive selection. The 103 most differentiated SNPs were tested for associations with metabolic traits, the most significant association was /rs174616 with body mass index (BMI).
