Article Abstract
Codium fragile (CF) is a type of green algae consumed as kimchi in Asia. UPLC-QTOF-MS/MS analysis showed that CF contain lysophosphatidyl choline, canthaxanthin, retinoic acid, α-tocopherol, and unsaturated fatty acids, which reportedly improve skeletal muscle health. However, the effect of CF on skeletal muscle mass and function remains to be elucidated. In mice fed with CF extracts, exercise endurance and muscle weight increased. CF extracts enhanced protein synthesis and myogenic differentiation through the mTORC1 pathway. CF extracts also promoted oxidative muscle fiber formation and mitochondrial biogenesis through the PGC-1α-related signaling pathway. Upregulation of PGC-1α by CF extracts was abolished by EX527 SIRT1 inhibitor treatment. Changed signaling molecules in the CF extracts were partially regulated by canthaxanthin, a new compound in CF extracts, suggesting that canthaxanthin contribute synergistically to the effect of CF extracts. Therefore, CF is a potential food source for sport nutrition or prevention of sarcopenia.

Mitochondrial mRNA oligocitydylation occurs in Chlorophyceae and Ulvales but not Bryopsidales or Trebouxiophyceae.

Mitochondrial mRNAs in the green algal class Chlorophyceae have non-template 3' oligo-cytosine-rich additions, also known as oligo(C), polycitydylation, or poly(C) "tails." These oligonucleotide additions are believed to be unique to green algal mitochondria, as none have been observed in any other organism. Among algae, oligocitydylation had only been observed in species within the Chlorophyceae, with no evidence of it occurring in other taxonomic classes.

Foliar application of biostimulants can be a valid option to reach the goal of sustainable intensification in agriculture, especially in extensive crops such as durum wheat. However, due to the wide range of active ingredients and their mixtures available in the market, the need to select the most efficient product in a specific growing environment is of dramatic importance to achieve remarkable results in yield and grain quality. To analyze the potential of different active ingredients, a field trial was performed in two consecutive growing seasons (2023 and 2024) under Mediterranean climatic conditions.

Seaweeds are promising natural sources of antimicrobials and antioxidants; however, their direct use is often limited by the lack of effective targeted delivery systems. The main objective of this study was to investigate the effects of liposomal encapsulation on enhancing the antimicrobial action of seaweed bioactives. A liposomal formulation was developed to encapsulate extracts from the green seaweeds and subsp.

This study investigated the effect of (WCF) water extract in reducing allergic inflammation in ovalbumin (OVA)-induced mice. Mice were sensitized to OVA + aluminum hydroxide, administered WCF for one week, and exposed to 1% aerosolized OVA. As a result, WCF intake reduced the OVA-induced increase in CD4 T cells, CD8 T cells, the T helper type 2 (Th2)/T helper type 1 (Th1) cell ratio, and inflammatory cells such as eosinophils and lymphocytes.

Dichotomosiphon tuberosus is one of the Bryopsidales, a siphonous, unicellular multinucleate ulvophyte. Bryopsidales typically occur in the ocean and contain unique carbonyl carotenoids siphonaxanthin (Sx) and its ester siphonein (Sn) in their major light-harvesting pigment-protein complexes, allowing them to utilize the green light available in the deep ocean for photosynthesis. However, unlike other Bryopsidales, D.
