Electrically charged food-grade biopolymers can be used to form multilayer coatings around the lipid droplets in oil-in-water emulsions using a sequential layer-by-layer electrostatic deposition approach. In principle, this approach improve stability and enhance functionality of food emulsions. study, were formed from saponins, polypeptides, polysaccharides medium chain triglyceride (MCT) as te...

Leishmania antigens are weak immunogens and need to be potentiated by various adjuvants and delivery systems. Alginate microspheres as an antigen delivery system and Quillaja saponins (QS) as an immunoadjuvant have been used to enhance the immune response against Autoclaved Leishmania major (ALM). Microspheres were prepared by an emulsification technique and characterized for size, encapsulatio...

Many immunostimulants act as vaccine adjuvants via activation of the innate immune system, although in many cases it is unclear which specific molecules contribute to the stimulatory activity. QS-21 is a defined, highly purified, and soluble saponin adjuvant currently used in licensed and exploratory vaccines, including vaccines against malaria, cancer, and HIV-1. However, little is known about...

The purpose of the study was to compare cytotoxicity two Quillaja saponaria bark saponin (QBS) mixtures against lung cell lines: normal MRC-5 fibroblast line and tumor A-549 epithelial cells lungs’ alveoli. study, performed both at a macro-scale in dedicated microfluidic device, showed that QBS more toxic abundant cholesterol (MRC-5). mixture with higher fraction found be cytotoxic towards line...

PURPOSE One of the most important tools against foot-and-mouth disease, a highly contagious and variable viral disease of cloven-hoofed animals, is vaccination. However, the effectiveness of foot-and-mouth disease vaccines on slowing the spread of the disease is questionable. In contrast, high potency vaccines providing early protection may solve issues with the spread of the disease, escaping ...

Saponins are detergent-like substances showing antibacterial as well as anticancer potential. In this study, the effects of saponins from Quillaja saponaria were analyzed against prokaryotic and eukaryotic cells. Multidrug-resistant clinical E. coli strains were isolated from human urine. As eukaryotic cells, the CHO-K1 cell lines were applied. Antibacterial effect of ampicillin, streptomycin, ...

This study investigated the effects of garlic oil (0.25 g/L), nitrate (5 mM), and quillaja saponin (0.6 g/L), alone and in binary or ternary combinations, on methanogenesis, rumen fermentation, and abundances of select microbial populations using in vitro rumen cultures. Potential adaptation to these compounds was also examined by repeated transfers of the cultures on alternate days until day 1...
