Docosahexaenoic acid (DHA) is a long chain poly-unsaturated fatty acid (LCPUFA) that has a role in the cognitive and visual development, as well as in the immune function of newborns. Premature infants are typically deficient in DHA for several reasons, to include fetal accretion of DHA that typically occurs during the third trimester. These premature infants are reliant on enteral sources of DHA, most commonly through breast milk. The DHA content in breast milk varies in direct correlation with maternal DHA intake and mothers consuming a Western diet typically have lower levels of DHA in their breast milk. Maternal DHA supplementation and direct supplementation of DHA to the infant has been tried successfully but there are still conflicting results on the optimal dosage and method of delivery of DHA to the infant. This has led to inconsistent results in trials evaluating the effects of DHA supplementation to the preterm infant in terms of cognitive and immunological outcomes. While short-term benefits have been seen in several studies, long-term benefits are not consistent. Future studies continue to be needed to optimize DHA intake in our premature infants.

Oleogels can replace animal fat and improve quality in gelled products. The effect of their structure characteristics on gelation mechanism was investigated from the multi-scale, and comparison of spatial structure and function from pork and golden pompano (Trachinotus ovatus) proteins was clarified. The results showed that increasing beeswax concentration facilitated molecular assembly and network structure, thus improving oil/water-holding capacity in fish and pork protein gels.

The complex fatty acid (FA) composition of the edible portion of American oysters () presents a significant analytical challenge to complete characterization. Here, we employed solvent-mediated covalent adduct chemical ionization to enable comprehensive characterization of its FA composition, with isotope ratio mass spectrometry for initial measurements of FA C signatures. Unusual polymethylene-interrupted (PMI) polyunsaturates were unequivocally identified, with 22:2(7,15) dominating at 5.

Fish is a source of long-chain omega-3 polyunsaturated fatty acids (LC n-3 PUFA) and methylmercury, a toxic heavy metal, with opposite effects on cardiovascular disease risk and cognitive decline. Besides diet, the apolipoprotein E (APOE) genotype may affect LC n-3 PUFA and mercury concentrations in the body, but the evidence is inconsistent. The subjects were 1159 men aged 42-60 years, examined in 1984-1989.

The performance of zinc-ion batteries (ZIBs) is often hindered by issues such as dendrite formation, hydrogen evolution, and limited cycling stability. 1,3-Dihydroxyacetone (DHA) not only stabilizes the anode by modulating the anode/electrolyte interface (AEI) but also enhances the electrochemical performance of the battery through its spontaneous and reversible keto-enol tautomerization, reducing the concentration gradient on the anode surface. Using a combination of DFT calculations and experimental characterization, the regulation of the hydrated Zn structure and its adsorption at AEI by this additive is investigated.

Empirical evidence indicates that the rate of wound healing varies through different seasons, where it is higher in spring and fall but lower in summer and winter, suggesting adequate temperatures may promote wound healing via an unknown mechanism. Here we show that adequate temperature facilitates wound healing by inducing the expression of Elongation of Very Long Chain Fatty Acid Elongase 4 (ELOVL4) that curtails the inflammation phase. Using skin injury and skin organoids models, bulk- and single-cell RNA-sequencing and spatial transcriptomics analysis, and functional perturbations, we first demonstrate that adjusting skin surface temperature to 20°C by contact cooling markedly increases the rate of wound healing via upregulating ELOVL4 in the injured epidermis.
