Chitosan films blended with stem, leaf and seed extracts of <italic>Pistacia terebinthus</italic> for active food packaging.
The growing interest in substituting synthetic products coming from non-renewable sources with biomass has focused attention on the lignin biopolymer. Its high availability, low price and properties make development of new valuable uses for interesting, thus improving economic environmental aspects conversion. To achieve this objective, potential use industrial kraft organosolv lignins as antioxidants, antimicrobials sunscreen been evaluated. results a detailed antibacterial antifungal study...
Flavonoid compounds are strong antioxidant and antifungal agents but their applications limited due to poor dissolution bioavailability. The use of nanotechnology in agriculture has received increasing attention, with the development new formulations containing active compounds. In this study, kaempferol (KAE) was loaded into lecithin/chitosan nanoparticles (LC NPs) determine activity compared pure KAE against phytopathogenic fungus Fusarium oxysporium resolve bioavailability problem....
Pullulan (Pull) decorated with monodisperse Ag and Au nanoparticles (NPs) was synthesized by a simple green method. Samples were characterized FTIR, UV–vis, NMR, XRD, TGA, SEM, XPS, DLS, TEM. SEM images showed highly oriented microforms reported for the first time Pull, because of supramolecular self-assembling behavior Pull chains. Antimicrobial quorum sensing (QS) inhibition activities tested against six pathogen bacteria reporter biomonitor strain. NPs, in particular, Ag-modified ones,...
Bio-based non-ionic hyperbranched polymers were synthesized as non-leachable antibacterial additives for other biopolymers.
Poly(MA-\textit{alt}-MVE)-$g$-PLA/ODA-MMT nanocomposite was prepared by self-catalytic interlamellar graft copolymerization of L-lactic acid (LA) onto poly(maleic anhydride-\textit{alt}-methyl vinyl ether) copolymer in the presence octadecyl amine-montmorillonite (ODA-MMT) organoclay. FTIR, $^{1}$H ($^{13}$C) NMR, XRD, and SEM-TEM were utilized for characterizing resultant nanocomposite. Laccase from \textit{Trametes versicolor} immobilized adsorption or covalent coupling. Decolorization...
The aim of this study was to develop simple cellulose nanocomposites that can interfere with the quorum-sensing (QS)-regulated physiological process bacteria, which will provide a sustainable and inexpensive solution serious challenges caused by bacterial infections in various products like food packaging or biomedical materials. Three 1-5 w% octadecylamine-modified montmorillonite (ODA-MMT) were prepared regeneration from ionic liquid solutions presence ODA-MMT suspension. Structural...
Quorum sensing (QS) is a chemical communication process that bacteria use to regulate virulence. Inhibition of QS (antiQS) overcomes the pathogenicity bacteria. Silver nanoparticles (AgNPs) have been used as antimicrobials against pathogens, but not QS-mediated bacterial infection. Also, studies carried out on inhibitory effects propolis based structures pathogen growth, no found their potential inhibitor. The present study aims investigate synthesis and characterization silver reduced with...
Most macromolecular antimicrobials are ionic and thus lack miscibility/compatibility with nonionic substrate materials. In this context, hyperbranched polyesters (HBPs) indole or isatin functionality were rationally designed, synthesized, characterized. Antimicrobial disk diffusion assay indicated that these HBPs showed significant antibacterial activity against 8 human pathogenic bacteria compared to small molecules groups. According DSC measurements, up 20% indole-based HBP is miscible...
Deep vein thrombosis (DVT) is a type of venous thromboembolism and clinically complex vascular disease. Oxidative stress serves key role in the pathogenesis numerous cardiovascular diseases, particularly endothelial dysfunction-associated syndromes. Nuclear factor erythroid-2-like 2(Nrf2) transcription primary regulator antioxidant responses. The levels reactive oxygen species (ROS) are regulated by Nrf2 its suppressor protein Kelch-like ECH-associated 1 (Keap1). However, to best our...
A series of new nonionic antimicrobial polymers with a biodegradable polyvinyl alcohol (PVA) backbone grafted indole units and different hydrophobic alkyl or ether groups were synthesized by facile esterification.
An elegant integration of primary amine-bearing segments into the acrylic acid-containing blocks and subsequent addition silver nanoparticles (Ag NPs) to this double hydrophilic block copolymer endowed resulting well-defined self-assembled construct with promising antimicrobial anti-quorum-sensing activity high cytotoxicity against breast cancer cells. Poly(N-vinylformamide) (PNVF), precursor amphoteric poly(vinyl amine) (PVAm), was chain-extended from pH-responsive poly(acrylic acid) (PAA)...
The solvent extraction of metal picrates such as Ni2+, Cu2+, Co2+, Pb2+ and Cd2+ from the aqueous to organic phase was studied using 2-(diphenylphosphino)aminopyridine (Ph2PNHpy). effects parameters including pH ligand solution volume were investigated determine ability for ions. results showed that percentages ions high at low values. antibacterial activity aminophosphine also screened against Escherichia coli (E. coli) ATCC 25922, Staphylococcus aureus (S. aureus) 25923, Pseudomonas...
