The accessibility of cellulase and xylanase enzymes to glucan and xylan, respectively, and its change with conversion were measured for pure Avicel glucan and poplar solids that had been pretreated by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), dilute acid, and lime. Avicel and pretreated solids were digested to various degrees by cellulase together with beta-glucosidase...

We conducted a double-blind placebo-controlled crossover pilot study to investigate the effect of oat betaglucans (β-glucan) on glycaemic control and variability in adults with type 1 diabetes (T1D; n = 14). Stomacol® tablets (1.53 g of β-glucan) or placebo (Plac) were administered three times daily before meals for two weeks. Glucose levels were monitored during the second week by continuous g...

Background and Purpose: Soleshine is a polyherbal preparation established in the market for the treatment of cracks and tinea pedis, which is applied externally. This preparation is composed of the extracts of indigenous plants, namely Azadirachta indica, Lawsonia alba, and Shorea robusta, mixed with castor oil and sesame oil. In the present study, an attempt was made to identify the constituen...

β-Glucans have been known to exhibit antitumor activities by potentiating host immunity by an unknown mechanism. The C-type lectin dectin-1, a β-glucan receptor, is found on the macrophage and can recognize various β-glucans. Previously, we demonstrated the presence of β-glucan receptor, dectin-1, on the Raw 264.7 cells as well as on murine mucosal organs, such as the thymus, the lung, and the ...

BACKGROUND While Candida pneumonia is life-threatening, biomarker measurements to early detect suspected Candida pneumonia are lacking. This study compared the diagnostic values of measuring levels of (1, 3)-β-D-glucan in endotracheal aspirate, bronchoalveolar lavage fluid, and serum to detect suspected Candida pneumonia in immunocompromised and critically ill patients. METHODS This prospecti...

The innate immune system differentially recognizes Candida albicans yeast and hyphae. It is not clear how the innate immune system effectively discriminates between yeast and hyphal forms of C. albicans. Glucans are major components of the fungal cell wall and key fungal pathogen-associated molecular patterns. C. albicans yeast glucan has been characterized; however, little is known about gluca...

The cell wall protects fungi against lysis and determines their cell shape. Alpha-glucan is a major carbohydrate component of the fungal cell wall, but its function is unknown and its synthase has remained elusive. Here, we describe a fission yeast gene, ags1(+), which encodes a putative alpha-glucan synthase. In contrast to the structure of other carbohydrate polymer synthases, the predicted A...

Plants evoke innate immunity against microbial challenges upon recognition of pathogen-associated molecular patterns (PAMPs), such as fungal cell wall chitin. Nevertheless, pathogens may circumvent the host PAMP-triggered immunity. We previously reported that the ascomycete Magnaporthe oryzae, a famine-causing rice pathogen, masks cell wall surfaces with α-1,3-glucan during invasion. Here, we s...

Barley ( Hordeum vulgare L.) has a storied history as food crop, and it long been dietary staple of peoples in temperate climates. Contemporary research studies have focused mostly on hulled barley for malt animal feed. As such, nitrogen (N) seeding rate agronomic data naked are lacking. In this study, we evaluated the effects N ß-glucan protein content, phenotypic characteristics barley, inclu...

An experiment (complete randomised design) was conducted to investigate the linear and quadratic effects of barley b-glucan inclusion level on total tract nutrient apparent digestibility, nitrogen excretion, intestinal microflora, volatile fatty acid (VFA) profile and manure ammonia emissions in pigs. Twenty-four boars (66 kg) were assigned to one of four treatments: (T1) 0 g/kg barley (control...
