    Inhibition of PDGF-induced migration and TNF-α-induced ICAM-1 expression by maltotetraose from bamboo stem extract (BSE) in mouse vascular smooth muscle cells.[Pubmed: 27067145]
    Expression of intercellular adhesion molecule-1 (ICAM-1) on vascular smooth muscle cells (VSMCs) plays an important role in the progression of atherosclerosis. We investigated the effects of bamboo stem extract (BSE) on motility and ICAM-1 expression by using mouse MOVAS-1 cells. Active constituents of BSE exhibiting an inhibitory activity on TNF-α-induced ICAM1 expression were identified using HPLC.METHODS AND RESULTS: The effects of BSE on platelet-derived growth factor (PDGF)-BB-induced migration, tumor necrosis factor alpha (TNF-α)-induced expression of ICAM-1, and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation were investigated. BSE inhibited migration of MOVAS-1 cells and sprout formation by mouse aorta explants. Reverse transcription PCR analysis and promoter reporter assays revealed that BSE suppressed ICAM-1 expression by inhibiting NF-κB activity. In addition, BSE reduced adhesion between VSMCs and monocytes. Several oligosaccharides were identified in BSE. Among the oligosaccharides contained in BSE, Maltotetraose and stachyose were potent inhibitors of TNF-α-induced ICAM-1 expression. We confirmed that Maltotetraose reduced PDGF-induced sprout formation by mouse aorta explants and inhibited TNF-α-induced NF-κB activation and ICAM-1 expression in MOVAS-1 cells. CONCLUSION: The BSE constituent Maltotetraose may be beneficial in the suppression of early atherosclerosis development and could be developed as a dietary supplement for cardiovascular health.

    Oligosaccharide synthesis in Fibrobacter succinogenes S85 and its modulation by the substrate.[Pubmed: 15885092 ]
    The hydrolytic properties of the isoenzymes of human pancreatic and salivary α-amylase (1,4-glucan 4-glucanohydrolase, EC were studied. The eight pancreatic isoenzymes split glycogen and starch into glucose, maltose, maltotriose, Maltotetraose and oligosaccharides of 5–10 glucose units. Maltotetraose is further digested to lower homologues. The percentage of conversion to these products is dependent on the substrate and varies from one isoenzyme to another. The six salivary isoenzymes split glycogen and starch into maltose, maltotriose, Maltotetraose, pannose and oligosaccharides of 5–10 glucose units. Maltotetraose and pannose are further digested to lower homologues. The percentage of conversion to these products is dependent on the substrate and is specific for each isoenzyme.

    Characterisation of brewpub beer carbohydrates using high performance anion exchange chromatography coupled with pulsed amperometric detection.[Pubmed: 24001825 ]
    High performance anion exchange chromatography (HPAEC) coupled with pulsed amperometric detection (PAD) was optimised in order to quantify mannose, maltose, maltotriose, Maltotetraose, maltopentaose, maltohexaose and maltoheptaose content of beer. The method allows the determination of above mentioned oligosaccharides, in a single chromatographic run, without any pre-treatment. Limit of detection and limit of quantification were suitable for beer. Accuracy and repeatability were good for the entire amount considered. Once optimised HPAEC PAD for the specific matrix, the second goal of this research was to verify the possibility to discriminate beers, depending on their style. The carbohydrates content of brewpub commercial beers was very variable, ranging from 19.3 to 1469mg/L (mannose), 34.5 to 2882mg/L (maltose), 141.9 to 20731mg/L (maltotriose), 168.5 to 7650mg/L (Maltotetraose), 20.1 to 2537mg/L (maltopentaose), 22.9 to 3295mg/L (maltohexaose), 8.5 to 2492mg/L (maltoeptaose), even in the same style of beer. However, the carbohydrates content was useful, jointed with other compounds amount, to discriminate different styles of beer. As a matter of fact, principal component analysis put in evidence beer differences considering some fermentation conditions and colour.
