Astaxanthin (AST), as natural hydrophobic nutrition, has exhibited health-promoting benefits for its outstanding antioxidant property. However, most studies tend to enhance its stability and solubility while the targeted delivery of AST is limited. In this study, liver-targeted nanocarriers were designed and prepared by lactobionic acid-modified (2-hydroxypropyl-β-cyclodextrin) for efficient controlled delivery of AST. The minimum average size of AST nanoparticles was about 98 nm with a polydispersity index (PDI) of 0.41. The lactobionic acid-modified AST nanoparticles exhibited significant cellular uptake, and an admirable ability to scavenge free radicals for HO-induced HepaRG cells in preventing mitochondrial depolarization. Moreover, accumulation of AST nanoparticles in liver was observed due to the modification of lactobionic acid (LA) of the nanocarriers through the specific binding of LA-asialoglycoprotein receptors. The results in this study provided a new idea for liver-specific nutrition delivery of AST in developing functional food for liver disease nutrition intervention.

The powerful antioxidant properties of astaxanthin (AST) face two significant challenges: low water solubility and poor chemical stability. To overcome them, extensive research and development efforts have been directed toward creating effective delivery systems. Among them, the positive synergistic effect between biomaterials can be used to refine the design of delivery systems.

Oral Lactoferrin-Responsive Formulation Anchoring around Inflammatory Bowel Region for IBD Therapy.

Adv Healthc Mater

Department of Oncology, The Second Affiliated Hospital, Medical School of Xi'an Jiaotong University, Xi'an, Shaanxi, 710061, China.

Oral formulation is the ideal treatment method for inflammatory bowel disease (IBD) therapy, but the mucosal damage and diarrhea symptoms impede the drug retention around the inflammatory region, severely limiting IBD therapeutic efficacy. To address this, an oral astaxanthin (Ast) precise delivery formulation is developed with the selective Ast anchoring around the inflammatory region by the novel lactoferrin (LF)-responsive flocculation. This formulation also heightens the apparent solubility of Ast with the minimized edible safety risks for the edible raw materials.

The aim of this narrative review is to summarize evidence relating the importance of nutrient intake from diet and supplementation for paediatric mental health. We begin by reviewing several mechanisms by which nutrients maximize brain health, including enabling metabolic reactions to occur, supporting mitochondrial function, reducing inflammation and assisting with detoxification. Circumstances that may contribute to an individual requiring additional nutrients beyond what are available in the diet, such as consumption of nutritionally depleted food, individual differences in biological need, long-term medication use and gut-brain health needs are then reviewed.

Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), a life-threatening disease, is typically induced by uncontrolled inflammatory responses and excessive production of reactive oxygen species (ROS). Astaxanthin (Ast) is known for its powerful natural antioxidant properties, showcasing excellent antioxidant, anti-inflammatory, and immunomodulatory effects. However, its poor water solubility and bioavailability significantly limit its efficacy.
