Delivering β-glucan via selected bakery systems : cake
… ways in developing a health-promoting diet. β-glucan, a soluble dietary fibre present in cereal grains, has many health benefits, which include reduction in blood cholesterol and, improving insulin response. Due to its viscosity enhancing and water binding properties, β-glucan is considered as …

Extractability and viscosity of β-glucan from oat bread during in vitro digestion
Oat β-glucan is well known for its health benefits, which are related to its rheological behavior in the gut. The objective of this thesis was to investigate the extractability and viscosity of β-glucan from oat bread under physiological conditions and to see whether there were varietal …

Regulation of (1,3;1,4)-β-Glucan Synthesis in Barley (<i>Hordeum vulgare</i> L.)
(1,3;1,4)-β-Glucan is the most abundant non-cellulosic polysaccharide that accumulates in the cell walls of barley grain. This polysaccharide is of importance because barley grains contain higher levels of (1,3;1,4)-β-glucan compared to other small grain cereals. Grain (1,3;1,4)-β-glucan …

Identification of genes involved in (1,3;1,4)-β-glucan synthesis in barley (<i>Hordeum vulgare</i>)
… walls in barley (Hordeum vulgare) is (1,3;1,4)-β-glucan, a polymer that has proven health benefits in the human diet, but that is undesirable for the brewing and distilling industry as it influences grain processability. Up to now, the main gene identified as having an involvement in …

Process-induced changes on the functionality of oat β-glucan evaluated using a gastrointestinal simulation model
Increasing the intake of β-glucan can lead to a reduction in LDL cholesterol and attenuation of postprandial blood glucose levels. Health-promoting effects of oat β-glucan are proposed to be related to its extractability, molecular weight (MW), and viscosity enhancement in the gastrointestinal (GI) …

Role of β-galactofuranose and β-glucan in Aspergillus nidulans hyphal cell wall ultrastructure and physical properties
… the external environment or chemical treatments. Glucan, chitin and mannan are the main components of the Aspergillus nidulans hyphal cell wall. The sugar β-galactofuranose is a minor component of the cell wall and thought to be responsible for cross-linking of the other cell wall components, …

The effects of dietary β-glucan supplementation on performance and immune response of broiler chicks during an Eimeria challenge
… is the use of immunomodulators such as β-glucan. A pilot study evaluated the effects of a yeast derived β-glucan (Auxoferm YGT) on growth performance and immune response of broiler chickens. Day-old chicks were fed a diet containing 0, 0.02, or 0.1% yeast β-glucan. On days 7 and 14 …

Effects of a yeast β-glucan supplement on symptoms of upper respiratory tract infection in free-living college-aged males
… has demonstrated that both oat and yeast ß-glucan benefits immunosuppressed populations. However, previous research has not, to our knowledge, investigated the effects of a yeast ß-glucan on the ummune functioning of healthy, free-living human populations. PURPOSE: The goal of this research …

Regulation of (1,3;1,4)-beta-glucan synthesis in barley (Hordeum vulgare L.) endosperm and leaf tissues.
… explore the regulatory mechanism for (1,3;1,4)-β-glucan synthesis in barley (Hordeum vulgare L.) in both endosperm and leaf tissues. For the grain (1,3;1,4)-β-glucan content regulation study, transcriptional profiles of candidate genes involved in (1,3;1,4)-β-glucan synthesis and degradation, from …

Development and evaluation of a beta-glucan biopolymer formulation of lactoferrin produced using a novel cryomilling technique
… In the present study, a natural polymer, β-glucan, was investigated as a protein carrier. A novel methodology was developed to produce microparticles encapsulating bovine lactoferrin (bLF), a whey protein from milk. β-glucan was investigated as a protein delivery candidate for the first time …

Regulation of reserve carbohydrates in hull-less barley grain
(1,3;1,4)-β-Glucans, which have many health benefits, represent the major cell wall component in barley endosperm. There have been a number of studies that have altered the amount of (1,3;1,4)-β-glucan in the grain, however, the effects of modifying (1,3;1,4)-β-glucan on various carbohydrate …

Reprogramming the immune environment in breast cancer via dendritic cells.
… We show that intratumoral delivery of β-glucan, a natural ligand for dectin-1 expressed on DCs, blocks the generation of iTh2 cells leading to decreased IL-13 in the tumor microenvironment and prevents breast cancer development in vivo. β-glucan inhibits OX40L expression on …

LPS, A TLR-4 AGONIST AND VIPER A TLR-4 INHIBITOR UPREGULATE PHAGOCYTOSIS OF ZYMOSAN IN BV2 CELLS
… which consists of structural carbohydrates β-1,3 glucan and O-mannan, recognized by pattern recognition receptors (PRR) β-glucan receptors found on the surface of microglia.<strong> </strong>In<strong> </strong>this study, we showed that the pro-inflammatory PAMP Lipopolysaccharide (LPS) causes an …

Functional Characterisation of the Eukaryotic Translation Elongation Factor 1Bγ in Aspergillus fumigatus; A Proteomic Systems Approach
… shorter germ tubes but reduced surface (1,3)-β-glucan in this mutant. Moreover, the reduced surface (1,3)-β-glucan explains the lower MIC of A. fumigatus Δpes3 to voriconazole measured in this study as surface (1,3)-β-glucan sequesters azoles preventing entry into the cell. Overall, this work …
