Summary: Photobacteriosis is a bacterial disease that affects various marine species globally, leading to significant economic losses. Despite studies on pathogen virulence and resistance, information on host defense mechanisms post-infection remains limited. This study focused on innate immune responses of farmed juvenile gilthead seabream after infection with Photobacterium damselae subsp. piscicida, revealing marked changes in blood parameters and gene expression related to inflammation and phagocytic activity. Further research on different fish species and pathogens could help identify health biomarkers for disease prevention in aquaculture.

Summary: This study investigated the effects of eco-organic feed on the growth performance, nutrient efficiency, feed utilization, and body composition of gilthead seabream. Different diets, including a control diet, four diets with 100% organic ingredients, and a control organic diet, were compared. The results showed that the growth rates were highest in fish fed the control organic diet and control diet with fishmeal. However, the poultry diet resulted in the lowest growth rate, survival rate, and highest feed conversion ratio. The use of organic diets of animal origin impacted the growth performance of gilthead seabream.

Summary: Specimens of Sparus aurata were exposed to sub-lethal concentrations of Hg and Cd for 25 days. Bioaccumulation of Hg was highest in gills, while Cd bioaccumulation was highest in the liver. Gills and skin were reliable targets for biomonitoring after short-term exposure. Exposure to both metals caused significant increases in metal concentrations in the kidney and liver. Biochemical analysis showed a reduction in lipid levels and decrease in polyunsaturated fatty acids (PUFA) in the liver, indicating oxidative stress. Molecular markers related to oxidative stress and lipid metabolism were also affected by exposure. The study suggests the possibility of using these biomarkers to explore fish metabolic responses to environmental pollution.

Summary: This study demonstrates the endogenous fatty acid metabolism of the marine rotifer, Brachionus plicatilis, and its ability to produce long-chain polyunsaturated fatty acids (LC-PUFA) from its precursors. The study also finds that the conversion rate of fatty acids is comparatively low, with a lower incorporation of docosahexaenoic acid (DHA) compared to other substrates. These factors, along with a competitive esterification pattern, may result in inadequate essential fatty acid ratios for marine larvae nutrition if not properly considered in the lipid enrichment process.

Summary: Recent findings suggest that changes in brain lipid composition during aging can affect the integrity and protein signaling of lipid rafts, leading to memory impairment. However, a n-3 LCPUFA-enriched diet has been shown to improve cognitive function and stabilize the lipid composition of hippocampal lipid rafts in aged mice. These findings suggest that n-3 LCPUFA supplementation may have a rejuvenating effect on the microenvironment of lipid rafts, enhancing cognitive performance.

Summary: The pathogenesis of obesity-related-renal disease is not clear, and the interaction between menopause and renal disease in obese women is still unknown. In this study, obese male and female mice developed albuminuria, hyperfiltration, and glomerulomegaly, and these changes were more severe in obese ovariectomized females. Obesity induced inflammation and an unbalanced lipidic profile in renal tissue, and this pattern seems to be enhanced in obesity after menopause.
