background: ionizing radiation induces the production of reactive oxygen species (ros), which play an important causative role in cell death. the aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from auricularia auricular (snaap). materials and methods: whole blood samples from healthy donors treated with snaap at different...

In this research, two types of sulfated polysaccharide derivatives were successfully synthesized. Their antioxidant activities were investigated by employing various established in vitro systems. In addition, the degree of sulfation was evaluated using ion-chromatography and IR spectra. The results verify that, when employing scavenging superoxide radical tests, both the sulfation of acid Auric...

Both edible fungal polysaccharides (Auricularia and Tremellan) Crataegus flavonoids promote the balance of dyslipidemia, which have a positive biological regulating effect on intestinal flora. In this study, extraction water-soluble from Auricularia Tremellan was investigated optimized firstly. Polysaccharides were then combined to study effects mediating role abnormal blood lipid concentration...

The functional formula diet AHP, containing polysaccharides from Auricularia auricular, polyphenolic compounds from Hawthorn (Crataegus) and Pueraria radix, has been recently developed as a dietary intervention against dyslipidemia in our previous study. In the present study, its antioxidant activities and protective effects against proliferation of vascular smooth muscle cells (VSMCs) were inv...

The objective of this study was to partially purify ß-glucanase from crude enzyme extract of straw mushroom (Volvariella volvacea). The crude enzyme extract was prepared from the fruiting bodies of straw mushroom. The ßglucanase was partially purified using an aqueous two-phase extraction with Triton X-114 and followed by ammonium sulfate precipitation in the range of 50-80% saturation. The ß-g...

Beta-glucosidase is among the suite of enzymes produced by white rot fungi (WRF) to biodegrade plant biomass. This study investigated the enzymatic activities and kinetic properties of β-glucosidase from seventeen WRF comprised of the following species from various geographical locations: Pleurotus ostreatus, Auricularia auricular, Polyporus squamosus, Trametes versicolor, Lentinula edodes, and...
