phleum alpinum/carbohydrate

On extraction of timothy pollen with aqueous buffer high molecular weight material (MW greater than 3,500) containing the sugars arabinose, fucose, xylose, mannose, galactose and glucose was rapidly released. When the allergen extract was subjected to crossed immunoaffinoelectrophoresis with lectins

Six kaempferol glycosides, four of them characterized for the first time, were isolated from the leaf extract of Lobularia maritima. The structural elucidation was performed by a combined approach using Electrospray-Ionization Triple-Quadrupole Mass-Spectrometric (ESI/TQ/MS) techniques, and 1D- and

BACKGROUND The introduction of molecular diagnoses has provided evidence of the existence of several different allergenic profiles in grass-sensitised individuals, reflecting the large number of allergens involved. This methodology has become a potent tool for a correct diagnosis and for the

Timothy (Phleum pratense L.) is an important grass forage used for pasture, hay, and silage in regions with cool and humid growth seasons. One of the factors affecting the nutritive value of this grass is the concentration of non-structural carbohydrates (NSC), mainly represented by fructans. NSC

The production of carbohydrates by cell suspension cultures of Phleum pratense (timothy grass) is described. Extracellular polysaccharides similar in monosaccharide composition to native cell wall polymers were accumulated, together with polymers of fructose (fructans). The fructans had similar

In vivo and in vitro allergenic activities of allergen and allergoid preparations from partially purified timothy pollen extract were measured in three different systems. In heterologous PCA titration, the allergen preparation was found to be 32 times more allergenic than the allergoid preparation.

Previous studies have shown that schistosome infection can protect against allergic symptoms, but the underlying mechanisms are still not fully understood. Here we have shown that rabbit IgG antibodies raised against Schistosoma mansoni soluble egg antigens (SmSEA) are cross-reactive with a wide
