13. Influence of drying methods on the physicochemical properties and nutritional composition of instant Tremella fuciformis
Abstract Instant Tremella fuciformis is ready to eat after adding hot water and is a delicious edible mushroom food. However, the drying method affects the quality of product. The present work evaluated the effects of freeze drying (FD), microwave drying (MD), and hot air drying (HAD) on shrinkage ratio, rehydration ratio, microstructure, polysaccharide and

14. Anatomical and histochemical studies of the somatic embryogenesis of Syagrus oleracea from immature inflorescences
Abstract Anatomical and histochemical studies were carried out during the somatic embryogenesis of Syagrus oleracea (Mart.) Becc. from immature inflorescences. Immature rachillas were inoculated on Murashige and Skoog medium with 4.52 μM 4-amino-3,5,6-trichloropicolinic acid (Picloram) and 2,4-diclorophenoxyacetic acid. Auxin concentrations were gradually r

15. Optimization of ultrasound-assisted enzymatic extraction and in vitro antioxidant activities of polysaccharides extracted from the leaves of Perilla frutescens
Abstract A Box-Behnken design was employed to optimize ultrasound-assisted enzymatic extraction of polysaccharides from perilla leaves. Four independent variables, namely, liquid-to-solid ratio, enzymatic time, enzymatic temperature, and ultrasonic power were investigated. Under the optimal liquid-to-solid ratio of 41:1, enzymatic time of 40 min, enzymatic t

16. Suppresses of Astragalus Polysaccharide on E. coli-Induced Injured Intestinal Microvascular through TLR4-NF-κB Signal Pathways in Chickens
ABSTRACT To investigate the hypothesis that APS can attenuate E. coli-induced microvascular dysfunction in chicken intestine, 60 0-day old male chickens were divided into three groups with 5 replications of 4 chicks. Chicken in the APS group were treated with 15 mg APS daily while the others were given 0 mg APS for 6 days. Then all 7-day old chicken were inj

17. Extraction and analysis of the parietal polysaccharides of acorn pericarps from Quercus trees
Abstract Acorns produced by Quercus trees are currently underexploited and undervalued. To evaluate the commercial and health benefits of acorns, we examined the cell wall components of acorn pericarps from Quercus suber and Quercus ilex, growing in North-Western Algeria. Acorn pericarps were sequentially extracted and the polysaccharide fractions were analy

18. EFEITO DO PH, ESPÉCIE E CONCENTRAÇÃO IÔNICA NA ABSORÇÃO DE ÁGUA DE HIDROGÉIS BIONANOCOMPÓSITOS CONSTITUÍDOS DE CMC/PAAM/LAPONITA RDS
The objective of this paper was to study the effect of pH, concentration and ionic species on the water absorption of the bionanocomposite hydrogels based on carboxymethylcellulose polysaccharide and laponite nanoclay. Bionanocomposite hydrogels were obtained via free radical polymerization. It was possible to observe that the swelling degree (Q) and kinetic

19. Mass Variation Rate, in Acidic Environment, of Polyhydroxybutyrate and Chitosan matrices with Potential Application as Controlled Drug Delivery System
Polymers such as the biocompatible polyhydroxybutyrate (PHB) and the polysaccharide chitosan (Chi), a pH-sensitive polymer, have been studied for drug delivery applications and scaffolds production. In this work, matrices of PHB and Chi were produced by compression molding (SPHB-Chi) and loaded with a broad-spectrum biocide chlorhexidine (CHX) (SPHB-Chi-CHX)

20. Termogravimetric Characterization of Biomass Impregnated with Biodegradable Ionic Liquids
ABSTRACT Different classes of solvents such as mineral acids and ionic liquids have proved to be capable of disrupting hydrogen bonds among different polysaccharide chains. Recently, a specific family of proticionic liquids (PILs) has been developed with functionality in various industrial applications, adding to the benefits and advantages of their use, sin

21. Nanostructured polymeric system based of cashew gum for oral admnistration of insulin
ABSTRACT The subcutaneous administration of insulin has been the treatment of millions of diabetics in the world. However, for such via insulin is invasive and not mimics the physiological action causing side effects. The oral route would be the most physiological and comfortable option, but the oral bioavailability of insulin is low by proteolytic activity

22. Effects and mechanisms of water-soluble Semen cassiae polysaccharide on retinitis pigmentosa in rats
Abstract This study aimed to investigate the effects and mechanisms of water-soluble Semen cassiae polysaccharide (SCP) on retinitis pigmentosa (RP) in rats. One hundred rats were randomly divided into control, model, and 50, 100 and 200 mg/kg SCP groups. The 50, 100 and 200 mg/kg SCP groups were treated with 50, 100 and 200 mg/kg SCP for 5 days, respectivel

23. Inhibitory effect of Astragalus polysaccharide on osteoporosis in ovariectomized rats by regulating FoxO3a /Wnt signaling pathway
Abstract Purpose: To investigate inhibitory effect of Astragalus polysaccharide (APS) on osteoporosis in ovariectomized rats by regulating FoxO3a/Wnt2 signaling pathway. Methods: Postmenopausal osteoporosis (PMOP) animal model was developed by excising the bilateral ovaries of rats. The model rats were administered with APS (200 mg/kg, 400 mg/kg, 800 mg/

24. Protective effect of Schisandra chinensis total lignans on acute alcoholic-induced liver injury related to inhibiting CYP2E1 activation and activating the Nrf2/ARE signaling pathway
ABSTRACT Schisandra chinensis (Turcz.) Baill., Schisandraceae, is a well-known traditional Chinese medicine used mainly as a recipe for hepatoprotection. Modern researches have revealed that the hepatoprotection is related to its lignans and crude polysaccharide. In this study, we examined the effect and mechanism of S. chinensis total lignans on the liver i
