Fabrication, modification, interaction mechanisms, and applications of fish gelatin: A comprehensive review.

Fish gelatin (FG) is an essential natural biopolymer isolated from aquatic sources and has been considered as a feasible substitute for mammalian gelatins. However, its inferior mechanical and gelling properties limit its applications. Consequently, FG has been modified using various methods.

Fucoxanthin Prevents Lipopolysaccharide-Induced Acute Lung Injury by Inhibiting Ferroptosis via Nrf2/STAT3 and Glutathione Pathways.

Fucoxanthin, sourced from marine brown algae, diatoms, and microalgae, is known to possess strong anti-inflammatory activity. To explore its intrinsic mechanism, we investigated its effects on acute lung injury (ALI) with an experiment using lipopolysaccharide (LPS)-induced RAW264.7 inflammatory cells and an ALI animal model.

Speciation analysis and toxicity evaluation of arsenolipids-an overview focusing on sea food.

Arsenic, which can be divided into inorganic and organic arsenic, is a toxic metalloid that has been identified as a human carcinogen. A common source of arsenic exposure in seafood is arsenolipid, which is a complex structure of lipid-soluble organic arsenic compounds. At present, the known arsenolipid species mainly include arsenic-containing fatty acids (AsFAs), arsenic-containing hydrocarbons (AsHCs), arsenic glycophospholipids (AsPLs), and cationic trimethyl fatty alcohols (TMAsFOHs).

Biomimetic triumvirate nanogel complexes via peptide-polysaccharide-polyphenol self-assembly.

Self-assembled peptide and polysaccharide nanogels are excellent candidates for bioactive delivery vectors. However, there are still significant challenges in the application of nanogels as delivery tools for bioactive elements. This study aims to deliver, and control the release of a hydrophobic bioactive flavonoid hesperidin.

Determining the potent immunostimulation potential arising from the heteropolysaccharide structure of a novel fucoidan, derived from .

A preliminary study was conducted of the chemical, structural properties and immunomodulatory activities of fucoidan isolated from (SZ). fucoidan (SZF) was determined to have a sulfate content of 19.74 ± 0.

Simple Complexity: Incorporating Bioinspired Delivery Machinery within Self-Assembled Peptide Biogels.

Bioinspired self-assembly is a bottom-up strategy enabling biologically sophisticated nanostructured biogels that can mimic natural tissue. Self-assembling peptides (SAPs), carefully designed, form signal-rich supramolecular nanostructures that intertwine to form a hydrogel material that can be used for a range of cell and tissue engineering scaffolds. Using the tools of nature, they are a versatile framework for the supply and presentation of important biological factors.

Chemical Characterization and Immunomodulatory Activity of Fucoidan from .

Fucoidan is a sulfated algal polyanionic polysaccharide that possesses many biological activities. In this paper, a fucoidan (SHF) polysaccharide was extracted from collected in the South China Sea. The SHF, with a molecular weight of 1166.

Extraction Optimization, UHPLC-Triple-TOF-MS/MS Analysis and Antioxidant Activity of Ceramides from Sea Red Rice Bran.

As a new type of salt-tolerant rice, sea red rice contains more minerals, proteins, and lipid compounds, and, in particular, its by-product rice bran may be used to replace other commercial rice brans as the main source of ceramides (Cers). However, the extraction rate of Cers is generally low, and it is crucial to seek an efficient extraction method. This study optimized the ultrasonic-assisted extraction of Cers from sea red rice bran using response surface methodology (RSM) and obtained a Cers yield of 12.

Chitosan/Alginate Nanoparticles for the Enhanced Oral Antithrombotic Activity of Clam Heparinoid from the Clam .

Chitosan/alginate nanoparticles (DG1-NPs and DG1/Cur-NPs) aiming to enhance the oral antithrombotic activity of clam heparinoid DG1 were prepared by ionotropic pre-gelation. The influence of parameters, such as the concentration of sodium alginate (SA), chitosan (CTS), CaCl, clam heparinoid DG1, and curcumin (Cur), on the characteristics of the nanoparticles, were investigated. Results indicate that chitosan and alginate can be used as polymer matrices to encapsulate DG1, and nanoparticle characteristics depend on the preparation parameters.

Isolation and Characterization of a Heparin-Like Compound with Potent Anticoagulant and Fibrinolytic Activity from the Clam .
