BACKGROUND Current standard medications for the treatment of allergic inflammation consist primarily of glucocorticoids and anti-histamines, but adverse side effects or insufficient responsiveness by patient subpopulations illustrate the need for safe and novel alternatives. Thus, there is a demand to develop a porcine model that is able to mimic mast cell-mediated type I hypersensitivity. Prev...

Powdered dry root bark of Securidaca longepedunculata was mixed with maize and cowpea and effectively reduced the numbers of Sitophilus zeamais and Callosobruchus maculatus emerging from these commodities, respectively, more than 9 months after treatment. This effect was reciprocated in grain treated with a methanol extract of the root bark, indicating that compounds were present that were ovip...

Much attention has been paid to diosgenin saponins because of their various bioactivities, whereas their gelation ability has never been reported. We synthesized some new saponins with pentose directly connected to diosgenin in a shorter procedure, which neither removed the acetyl group of the anomeric hydroxyl group selectively nor activated it and led to a higher yield, compared with the comm...

1. Immature, male Wistar rats were allocated to one of six groups and caged individually. The first group was given a semi-synthetic diet containing 38 mg iron and 55 mg zinc/kg (basal group). The second and third groups were given a diet containing 10 mg Zn and 12 mg Fe/kg respectively (low-Zn and low-Fe groups). Groups four, five and six were given similar diets containing 20 g Gypsophila sap...

Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...

Threats connected with contamination of environment heavy metals include negative influence on human and animal health also negatively the biodiversity ecosystems. While applying various techniques metal remediation from soils, an important problem is adsorption ions solid particles. In this respect, composition properties soil strongly affect efficiency process. Therefore, aim study was to det...

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...
