The Shocking Truth About The Keto Diet | Dom D'Agostino on Health Theory Glucans are polycaccharides composed of D-glucose monomers linked by glycosidic bonds. Numbering of both alpha and beta glucans relate to the number of the carbon . Effects after inhalation of (1 -> 3)-beta-D-glucan and relation to mould . We use science and innovation to provide accurate data that people trust.

It is present in virtually all of the grains, fruits, and vegetables that we eat. It is a part of the diet of omnivores including humans and herbivores. Omnivores digest only a fraction of ingested cellulose; the rest is considered "roughage.

It is administered intravenously as an anticancer agent. Like lentinen, it has anti-cancer properties and is an immunostimulant. It is an inflammatory agent that stimulates macrophage activation.

Glucan Exposure Glucans are commonly ingested, and as mentioned above, are injected in some medical procedures. Glucans are also commonly inhaled, since all airborne fungal spores have cell walls containing primarily beta glucan. Glucan-containing airborne particles tend to be in the large particle fraction of indoor and probably also outdoor aerosols Chen and Hildeman ; Menetrez et al.

The vast majority of fungal glucan exposure occurs outdoors. In a similar study, Lee et al. Positive Health Effects of Glucans Exposure to glucans is natural and occurs throughout life.

Health Effects of Glucans

They have been shown to be immunostimulants, and may contribute to the early development of the immune system in newborns. Glucans have been widely studied as anti-cancer agents Ma et al. In the laboratory, positive effects on lung cancer Zhong et al.

Glucan oral supplements have also been studied in relation to their effect on glucose metabolism and diabetes Nazare et al. They are also advertised as an aid to weight loss, however Beck et al.

Talbott and Talbott found positive effects of beta-glucan supplements on respiratory disease fewer symptomsvigor, tension, fatigue and confusion. Negative Health Effects of Glucans There is considerable controversy about the negative health effects of exposure to beta-glucans. Some evidence has been found that inhalation of glucans can be irritating.

Inhalation challenges have resulted in stimulation of inflammatory cells Beijer et al. Only those with nasal hyperreactivity from some previous cause reacted to the exposures.

In another chamber study Bonlokke et al. They considered glucan to have a stimulatory effect when other particles are present. They and others e. In the laboratory, Holck et al. On the other hand, several research groups report no health related effects associated with inhalation of indoor glucans Codispoti et al. This lack of effect was confirmed by Stuurman et al. Measurement of Glucans Glucans have been collected both from dust and from air, and measurement of glucans is used for the detection of invasive fungal infections Patterson A Limulus assay, that is similar to the endotoxin assay, is the most common method used for sample analysis.

The molecular basis of these assays is described by Muta Both rely on the effects of these chemicals on horseshoe crab leucocytes.

More recently, sensitive immunoassays have been developed that use monoclonal antibodies. These assays have enabled the measurement of low level glucans in air Noss et al. Oat beta-glucan supplementation does not enhance the effectiveness of an energy-restricted diet in overweight women. British Journal of Nutrition 8: Mediators of Inflammation FOS are a subject of interest because of their prebiotic and antioxidant potential [ 25 ].


Materials and Methods 2. All chemicals used were of analytical grade.

Preparation of Feruloylated Arabinoxylan Mono- and Oligosaccharides Extracts Feruloylated arabinose was prepared from corn bran using mild acid hydrolysis [ 27 ] and feruloylated arabinoxylan oligosaccharides were prepared from wheat aleurone using xylanase treatment [ 26 ]. Specifically, hand dissected corn bran was obtained according to a method by Ndolo and Beta [ 28 ].

Both wheat aleurone and corn bran flour were destarched and deproteinised according to a method by Malunga and Beta [ 26 ]. The supernatant was freeze dried. The samples were reconstituted with 10 mL millique water and further purified on XAD2 column as described by Saulnier et al. XAD2 column was preconditioned with 1 column volume ethanol.

After sample loading, it was eluted with 1 column volume water, 1. The extracts were reconstituted with water and freeze dried. Chemical Composition of Feruloylated Arabinoxylan Mono- and Oligosaccharides Monosaccharide composition, FA content, and protein content were analyzed as described previously by Malunga and Beta [ 30 ].

All experiments were carried out on cells of passage number 15 to 25 and media were refreshed 3 hours prior to experiments. The supernatant was analyzed for protein content using Lowry method. Briefly, rat intestinal acetone powder mg was mixed with 10 mL sodium phosphate buffer pH 6. After centrifugation at g for 10 minutes, the supernatants were collected for glucose analysis using Megazyme GODP glucose test kit. Acarbose concentrations of 1. After 24 hours, the oocytes were injected with The oocytes were incubated for 72 hours with media change every 12 hours.

FAXmo were dissolved in OR-2 containing calcium chloride without pyruvate at concentrations shown in the results section. OR-2 buffer was used as a control. After 30 minutes, transport buffer was aspirated and 1 mL ice cold OR-2 buffer was added to terminate glucose transport. The oocytes were washed four times with ice cold buffer. After 10 minutes, 5 mL scintillation cocktail was added prior to reading on scintillation spectrometry Perkin-Elmer, Canada. The internalized glucose was expressed as counts per minute beta cpma per oocyte.

Mutarotation — Master Organic Chemistry

Statistical Analysis All cell culture experiments were done in three different generations of cells and data represents mean and standard deviation of at least six results that were similar. Each data point for glucose uptake in oocytes represents mean of 15—20 oocytes.

Correlations between FAXmo and inhibition capacity were done by Pearson's correlation test.
