All available information has always been presented in the form of static world maps or large dimension tables, so that it would benefit from the newly available visualization tools, such as interactive world maps. Taking all this into consideration, the aims of the present review were (1) to gather and summarize all available information on LNP and LP genetic mechanisms and evolutionary adaptation theories, and (2) to create online interactive world maps, including all LP phenotype and genotype frequency data reported to date. As Lactose-N-neotetraose , we have created two online interactive resources, which constitute an upgrade over previously published static world maps, and allow users a personalized data exploration, while at the same time accessing complete reports Conflict of interest statement The authors declare no conflict of interest.Structure of the capsular polysaccharide from Alteromonas sp. CMM 155.Zubkov VA(1), Nazarenko EL, Gorshkova RP, Ivanova EP, Shashkov AS, Knirel YA, Capsular polysaccharide (CPS) was obtained by water-saline extraction of the Alteromonas sp.

CMM 155. On the basis of solvolysis with anhydrous HF and 1H- and 13C-NMR spectral data, including NOE experiments, it was concluded that the capsular polysaccharide had the following structure containing novel N-acyl-amino sugar and bacillosamine residues -- 3)-alpha-D-GalpNAc-(1 -- 4)-alpha-L-GalApNAc(1 -- 3)- alpha-D-QuipNAc4NAc-(1 -- Method of preservation and type of protective agent strongly influence probiotic properties of Lactococcus lactis A complete process of probiotic preparation Archacka M(1), Białas W(2), Dembczyński R(3), Olejnik A(4), Sip A(5), In order to assess the essential probiotic properties of a strain dedicated for administration in humans and animals, characteristics of finally formulated products, rather than the cells solely, seems to be of crucial importance. In this study, composition of protective blends for manufacture of L. lactis probiotic powders was optimized using a statistical experimental design. The powders, generated by either spray- or freeze-drying techniques, were subsequently subjected to storage testing, and in vitro digestion in simulated stomach and small intestine. Finally, maintenance of adherence capability to human enterocyte-like cell lines, was evaluated. Our data demonstrated that % trehalose ensures the highest viability of L.

lactis bacteria upon both drying techniques (viability of -68%). Moreover, skimmed Fucosylated Lactose -protected spray-dried cells exhibit the highest resistance to harsh environmental conditions of stomach (53 ± 7% survival rate) and higher adhesion ability to HT-29 cell line after digestion (528 ± 29 cells per 0 epithelial cells).O-glycosylation of α-1-acid glycoprotein of human milk is lactation stage Orczyk-Pawiłowicz M(1), Berghausen-Mazur M(2), Hirnle L(2), Kątnik-Prastowska BACKGROUND Human milk provides a multitude of glycoproteins, including highly glycosylated α-1-acid glycoprotein (AGP), which elicits anti-inflammatory and immunomodulatory properties. The milk AGP glycoforms may provide the breastfed infant with a wide range of biological benefits. Here, we analyzed the reactivity of O-linked sugar-specific lectins with human milk AGP over the process of lactation and compared the results with those of the lactating MATERIALS AND METHODS Relative amounts of human skim milk AGP O-glycans were analyzed in early colostrum, colostrum, and transitional and mature milk samples of 127 healthy mothers by lectin-AGP enzyme-linked immunosorbent assay using sialyl T (sialyl-α2,3α2,6 Galβ1,3GalNAc-), asialyl T (Galβ1,3GalNAc-), and Tn Arachis hypogaea (PNA), and Vicia villosa (VVA) lectins, respectively.RESULTS Milk AGP elicited high expression of Jacalin- and PNA-reactive glycotopes and low expression of VVA-reactive glycotopes, which were absent on plasma AGP of lactating mothers and healthy individuals. The expression of sialyl, asialyl T, and Tn glycotopes of human milk AGP was lactation stage related.

The relative amount of Jacalin-reactive AGP glycotope was highest in the colostrum samples and then decreased starting from Day 8 of lactation. In contrast, an increase of the relative amount of PNA-reactive glycotope with milk maturation was observed. The relative amount of VVA-reactive glycotope remained almost constant over the development of lactation.CONCLUSIONS Milk AGP differs from mother's plasma AGP by the presence of O-linked sialylated and asialylated T as well as Tn antigens. The variation of the expression of sialylated and asialylated T and Tn antigens on AGP is Enteral feeding composition and necrotizing enterocolitis.
