Oil palm, a tropical woody oil crop, is widely used in food, cosmetics, and pharmaceuticals due to its high production efficiency and economic value. Palm oil is rich in free fatty acids, polyphenols, vitamin E, and other nutrients, which are beneficial for human health when consumed appropriately. Therefore, investigating the dynamic changes in free fatty acid content at different stages of development and hypothesizing the influence of regulatory genes on free fatty acid metabolism is crucial for improving palm oil quality and accelerating industry growth. LC-MS/MS is used to analyze the composition and content of free fatty acids in the flesh after 95 days (MS1 and MT1), 125 days (MS2 and MT2), and 185 days (MS3 and MT3) of Seedless (MS) and Tenera (MT) oil palm species fruit pollination. RNA-Seq was used to analyze the expression of genes regulating free fatty acid synthesis and accumulation, with differences in genes and metabolites mapped to the KEGG pathway map using the KEGG (Kyoto encyclopedia of genes and genomes) enrichment analysis method. A metabolomics study identified 17 types of saturated and 13 types of unsaturated free fatty acids during the development of MS and MT. Transcriptomic research revealed that 10,804 significantly different expression genes were acquired in the set differential gene threshold between MS and MT. The results showed that FabB was positively correlated with the contents of three main free fatty acids (stearic acid, myristate acid, and palmitic acid) and negatively correlated with the contents of free palmitic acid in the flesh of MS and MT. ACSL and FATB were positively correlated with the contents of three main free fatty acids and negatively correlated with free myristate acid. The study reveals that the expression of key enzyme genes, FabB and FabF, may improve the synthesis of free myristate in oil palm flesh, while FabF, ACSL, and FATB genes may facilitate the production of free palmitoleic acid. These genes may also promote the synthesis of free stearic acid and palmitoleic acid in oil palm flesh. However, the FabB gene may inhibit stearic acid synthesis, while ACSL and FATB genes may hinder myristate acid production. This study provides a theoretical basis for improving palm oil quality.

Background: Lower extremity arterial disease is a prevalent vascular condition leading to ischemic symptoms and increased risk of cardiovascular events. Drug-eluting stents have improved outcomes by reducing restenosis, with sirolimus emerging as a promising alternative to paclitaxel due to its safer profile. This study evaluates the efficacy and safety of novel polymer-free Amphilimus formulation (Sirolimus + fatty acid) eluting self-expanding stent in the treatment of femoropopliteal disease in a real-world population.

Huajiao seeds represent an underutilized high-quality woody oilseed resource rich in unsaturated fatty acids and diverse nutritional factors. This study investigated the quality characteristics and digestive behavior of two Huajiao seed oils (Zanthoxylum bungeanum seed oil (ZBSO) and Zanthoxylum schinifolium seed oil (ZSSO)). The results demonstrated that both oils were rich in unsaturated fatty acids, with ZBSO containing 76.

Lutein and omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), offer significant health benefits, especially when consumed together. However, their incorporation in food is often low due to their instability during processing and storage. Meat products play an essential role in human nutrition and are generally deficient in lutein and omega-3 fatty acids.

In Brief: Lipid homeostasis is vital for maintaining testicular function and male fertility, but the specific contributions of lipid-regulating enzymes remain unclear. This study shows that DGKη, although highly expressed in the testis, is not essential for spermatogenesis but modulates testicular lipid metabolism in response to dietary conditions.
Abstract: Diacylglycerol kinase eta (DGKη), encoded by the Dgkh gene, catalyzes the phosphorylation of diacylglycerol to phosphatidic acid, both of which are key lipid second messengers.
