37. Residual polysaccharides from fungi reduce the bacterial spot in tomato plants
Abstract Polysaccharides from fungal wastes were partially characterized and evaluated for their protective effects against bacterial spot caused by Xanthomonas gardneri on four tomato cultivars: Santa Cruz Kada, Natália, BRS Sena and Forty. The polysaccharides were extracted from spent mushroom substrate of Pleurotus ostreatus, residual brewery yeast (Sacc

38. Identification of the alpha-enolase P46 in the extracellular membrane vesicles of Bacteroides fragilis
BACKGROUND Members of the Bacteroides fragilis group are the most important components of the normal human gut microbiome, but are also major opportunistic pathogens that are responsible for significant mortality, especially in the case of bacteraemia and other severe infections, such as intra-abdominal abscesses. Up to now, several virulence factors have b

39. Combination of Propylene Glycol Alginate and Lauric Acid on Water Retention and Mechanical Properties of Soy Protein Isolate-Based Films
The water sorption, water barrier properties and mechanical behavior of soy protein isolate (SPI) based films combined with propylene glycol alginate (PGA) and lauric acid (La) via a direct- or co-dried blending process were investigated. Higher water retention ability and a single glass transition temperature (Tg) were found when the PGA was added to form d

40. Effect of Non-Starch Polysaccharide (NSP) of Wheat and Barley Supplemented with Exogenous Enzyme Blend on Growth Performance, Gut Microbial, Pancreatic Enzyme Activities, Expression of Glucose Transporter (SGLT1) and Mucin Producer (MUC2) Genes of Broiler Chickens
ABSTRACT The experiment was carried out in a completely randomized design (CRD) with 625 broiler chicks (Ross 308) for 5 repetitions (25 birds per each replicated) on the 5 treatments diet. Treatments included two different types of cereal grains (wheat, and barley) with or without an enzyme supplementation along with a corn-based diet as control group. The

41. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

42. Inhibitory effect of Dendrobium officinale polysaccharide on human gastric cancer cell xenografts in nude mice
Abstract This study investigated the inhibitory effect of Dendrobium officinale polysaccharide (DOPA) on human gastric cancer cell SGC-7901 xenografts in nude mice. The nude mice with SGC-7901 xenografts were randomly divided into model, 5-fluorouracil (5-Fu), low-dose DOPA, middle-dose DOPA and high-dose DOPA group. The later four groups were intragastrical

43. Yeast extract elicitation increases vinblastine and vincristine yield in protoplast derived tissues and plantlets in Catharanthus roseus
Abstract Catharanthus roseus (L.) G. Don, Apocynaceae, is an immensely important medicinal plant, produces a variety of anticancerous compounds. The yield of two most investigated alkaloids vinblastine and vincristine is unfortunately very low. A vast array of technologies including elicitation have recently been used to enrich Catharanthus alkaloid in cultu

44. Effects of tin caulis dendrobium polysaccharide on the prevention of non-alcoholic fatty liver disease in rats
ABSTRACT We aimed to investigate the effects and mechanisms of tin caulis dendrobium polysaccharide on body weight and non-alcoholic fatty liver disease in Sprague-Dawleg rats. The rats were fed a high-fat diet (HFD) with or without tin caulis dendrobium polysaccharide for eight weeks. Body weight, liver function tests, serum and liver lipids, liver morpholo

45. Development and characterization of pullulan-polymethacrylate free films as potential material for enteric drug release
ABSTRACT Free films of pullulan-polymethacrylate associations were produced by casting process to develop a novel target-specific material. For characterization, tests of water vapor permeability, swelling index, infrared absorption spectroscopy, thermogravimetric analysis, scanning electron microscopy and mechanical analysis were performed. The polysacchari

46. Polysaccharide rich fractions from barks of Ximenia americana inhibit peripheral inflammatory nociception in mice Antinociceptive effect of Ximenia americana polysaccharide rich fractions
Abstract Ximenia americana L., Olacaceae, barks are utilized in folk medicine as analgesic and anti-inflammatory. The objective was to evaluate the toxicity and antinociceptive effect of polysaccharides rich fractions from X. americana barks. The fractions were obtained by extraction with NaOH, followed by precipitation with ethanol and fractionation by ion

47. MODIFICAÇÃO QUÍMICA DA PECTINA DO MELÃO CAIPIRA (Cucumis melo VAR. ACIDULUS)
Melon is one of the most widely consumed fruits in the world. In Brazil, 60% of the production is for domestic consumption, with these fruits deemed to be of lower commercial value. For the first time, pectin has been extracted from this species of melon. So the extraction of this polysaccharide can be used as an alternative to increase the value of the frui

48. Effects of Dendrobium officinale polysaccharide on adipogenic differentiation of rat bone marrow mesenchymal stem cells
Abstract This study investigated the effect of Dendrobium officinale polysaccharide (DOP) on the adipogenic differentiation of rat bone marrow mesenchymal stem cells (BMSCs). DOP was extracted fresh Dendrobium officinale. Rat BMSCs were prepared, and then were treated with 0 (control), 50, 100, 200, 400, 800 μg/mL DOP, respectively. The cell viability was d
