Spray drying the Pickering emulsions stabilized by chitosan/ovalbumin polyelectrolyte complexes for the production of oxidation stable tuna oil microcapsules.

The microencapsulation of polysaturated fatty acids by spray drying remains a challenge due to their susceptibility to oxidation. In this work, antioxidant Pickering emulsions were attempted as feeds to produce oxidation stable tuna oil microcapsules. The results indicated that the association between chitosan (CS) and ovalbumin (OVA) was a feasible way to fabricate antioxidant and wettable complexes and a high CS percentage favored these properties.

Composite formation of whey protein isolate and OSA starch for fabricating high internal phase emulsion: A comparative study at different pH and their application in biscuits.

The composites formed by whey protein isolate (WPI) and octenyl succinate anhydride (OSA)-modified starch were characterized with a focus on the effect of pH, and their potential in fabricating high internal phase emulsions (HIPEs) as fat substitutes was evaluated. The particles obtained at pH 3.0, 6.

A novel protein from Eupolyphaga sinensis inhibits adhesion, migration, and invasion of human lung cancer A549 cells.

Eupolyphaga sinensis Walker is an important insect used in Chinese traditional medicine. In this study, we purified a 72-kDa anticancer protein, designated as EPS72, from this species using ammonium sulfate precipitation, ultrafiltration, CM Sepharose Fast Flow cation exchange, Q Sepharose High Performance (HP) anion exchange, Butyl Sepharose HP hydrophobic chromatography, and Superdex 75 gel filtration chromatographic techniques. EPS72 exhibited a potent anticancer activity against the human lung cancer A549 cell line (IC50, 18.

[Oleanolic acid inhibits proliferation of HUVECs, and inhibits migration and tube formation via VEGF pathway].

To investigate the effects of oleanolic acid (OA) on the proliferation, migration and the formation of tube-like structure in human vascular endothelial cells (HUVECs). MTT assay, flat plate scarification, Transwell plates and matrigel-induced tube formation assay were performed to detect the effects of OA on proliferation, migration and tube formation. MTT assay showed that the inhibition rates of HUVECs treated with 60 and 100 microg x mL(-1) of OA for 24 h were 19% and 83% respectively.
