In this study, a pectin polysaccharide, AER-A3 (Mw 1.12 × 105 g/mol), was isolated and purified from the root bark of Aralia elata by ion exchange and gel-filtration chromatography. Its planar structure was investigated in combination with UPLC-ESI-MS, FT-IR, HILIC-ESI--MS/MS, GC-MS and NMR techniques. The main chain of AER-A3 was unambiguously determined to be smooth region and hairy region with a chain length ratio of 11 characterized by occurrence of (1 → 2)-α-Rhap, (1 → 2,3)-α-Rhap, (1 → 2,4)-α-Rhap, (1 → 2,3,4)-α-Rhap, and (1 → 4)-α-GalpA, whereas the branched chain included T-α-Araf, (1 → 5)-α-Araf, (1 → 3,5)-α-Araf, T-β-Galp, (1 → 3)-β-Galp, (1 → 3,4,6)-β-Galp, (1 → 4)-Glcp, (1 → 3)-Glcp, and (1 → 3)-Manp. In addition, SEC-MALLS-RID, CD and Congo red assays showed that AER-A3 had no helical conformations but existed as a globular shape with branching. AER-A3 had good scavenging activities against DPPH, hydroxyl, and superoxide radicals. Anti-tumor assay investigated the effects of AER-A3 on human A549 and HepG2 cancer cell lines in vitro. These results provided a scientific basis for the use of the polysaccharides in A. elata root barks in pharmaceuticals.Cisplatin (cis-Diaminedichloroplatinum) is one of the most effective chemotherapeutic because of its anti-neoplastic properties against various types of tumor. However, it has a wide variety of side effects such as hepato, gastrointestinal, neuro, nephro, and cardiotoxicity (acute and/or chronic) that highly restricted its usage. Thus, research work was planned to detect the role of gold (AuNPs), silver nanoparticles (AgNPs) and Ag@AuNPs as core-shell in enhancing the benefits of blackberry extract in treatment of cisplatin-induced cardiotoxicity. In our work, solid-state process was used in order to prepare these nanoparticles using pectin as an ecologically friendly-polymer for ions reduction and at the same time as stabilizing agent for the produced nanoparticles. This nominated method for large-scale preparation of nanoparticles is simple, efficient, and convenient. The presence of individual metallic Ag, Au and both has been proven by UV-vis spectroscopy. Transmission electron microscopy (TEM) and particmarkers were significantly increased in cispt group compared to control; whereas these parameters were attenuated in all treated groups in particular that received blackberry (bb) loaded Ag@AuNPs. Based on these results, it can be concluded that bb, has antioxidant and antilipidemic effect that help in protecting against cardiovascular disease specially when loaded with Ag@AuNPs that enhance its properties.Polypeptide-mediated silica mineralization is an attractive approach to prepare polypeptide/silica nanocomposites for enzyme immobilization. Herein, a facile approach for in situ immobilization of catalase (CAT) in polypeptide/silica nanocomposites is developed via the preparation of cross-linked polypeptide/enzyme microgels using an emulsion process followed by silica mineralization. The efficient protein immobilization under benign condition (25-28 °C, pH 7.0, 0.05 N) was evidenced by high immobilization yield (> 99%) and no protein leakage. Our data showed that the immobilized CAT exhibited prolonged reusability and storage stability compared to free one, suggesting that the composite networks not only provide suitable microenvironments to facilitate enzymatic reactions but also confine the enzyme macromolecules to prevent subunit dissociation. Star-shaped topology exhibited better coverage onto the enzyme than linear counterpart, leading to the superior reusability (relative activity >95% for 30 cycling number) and storage stability (relative activity >95% for 60 days) of the immobilized CAT (~ 14 mg/g of support). The substrate affinity and enzymatic reaction rate for the immobilized CAT were also influenced by silica content and polypeptide topology. This strategy may provide a feasible and inexpensive approach to fabricate polypeptide/silica nanocomposites, which would be promising materials in biotechnological fields such as enzyme immobilization.In this study, the effects of various fatty (including caprylic, lauric, and palmitic) acids on physicochemical, mechanical, and barrier properties of basil seed gum (BSG)-based edible films were investigated. The introduction of fatty acids (FAs) into the BSG-based matrix was confirmed by FT-IR. Increasing the FA chain length resulted in an increase in the thickness and opacity of FA-modified BSG films, while water solubility decreased. The water vapor permeability (WVP) of FA-modified films was significantly (P less then 0.05) lower than that of control film. The mechanical properties and color attributes of edible films were improved after incorporating caprylic and lauric acids. SEM micrographs revealed a more homogenous microstructure with a higher surface density in the films incorporated with caprylic acid, while a higher roughness and insoluble particles were observed in those incorporated with lauric, and palmitic acids. Our findings showed that lauric acid is a good candidate for improving the barrier and textural characteristics of BSG-based edible films.The escalation of fine particulate matter (PM) air pollution has recently become a global concern. Evidence is fast accumulating on PM exposure-related skin damage. The present study explored the therapeutic potentials of fucoidan purified from Sargassum natans against damaging effects of PM exposure on human HaCaT keratinocytes. Fucoidan (SNF7) was purified from S. natans by an enzyme-assisted extraction and purified by anion exchange chromatography. SNF7 (≈50 kDa) was identified as a fucoidan containing 70.97% fucose and 36.41 ± 0.59% of sulfate. Treatment of fine dust from Beijing, China (CFD) increased intracellular ROS levels in HaCaT cells triggering DNA damage and apoptosis. Pifithrin-α Treatment of SNF7 dose-dependently attenuated CFD-induced surge of intracellular ROS levels in keratinocytes by increasing antioxidant defense enzymes. Moreover, SNF7 chelated metal ions Pb2+, Ba2+, Sr2+, Cu2+, Fe2+, and Ca2+ coming from CFD. The results substantiated the potential therapeutic effects of SNF7 against CFD-induced oxidative stress.
