As Seebio 2'-Fucose lactose , novel technologies for glycomics applications have been developed, including carbohydrate microarrays and label-free detection methods. In this paper, we report using the combination of oligosaccharide microarrays and the label-free oblique-incidence reflectivity difference (OI-RD) microscopy for real-time characterization of oligosaccharide binding proteins. Aminated human milk oligosaccharides were immobilized on epoxy-coated glass substrates as microarrays for reactions with Family 1 of solute binding proteins from Bifidobacterium longum subsp. infantis (B. infantis). Binding affinities of these protein-oligosaccharide interactions showed preferences of Family 1 of solute binding proteins to host glycans, which helps in characterizing the complex process of human milk oligosaccharides Use of proteomic methodology for the characterization of human milk fat globular Characterization of the major human milk fat globular membrane proteins was carried out using proteomic techniques comprising two-dimensional polyacrylamide gel electrophoresis, followed by in situ PNGase F and trypsin digestion.

Matrix-assisted laser desorptionionization quadrupole time-of-flight and electrospray ionization mass spectrometry identified seven major protein components alpha-lactalbumin, lysozyme precursor, beta-casein, clusterin, lactotransferrin, polymeric immunoglobulin receptor precursor, and human milk fat globule EGF-factor 8 protein. Sequence information on the protein-associated glycans was determined by matrix-assisted laser desorption-ionization quadrupole time-of-flight hybrid mass spectrometry. This glycan analysis revealed interesting fucosylation branching patterns which may be influential in maternal protection of the newborn against bacterial and viral pathogenic attack.Application of Wood's model to lactation curve of Italian Heavy Draft horse The aim of this work was to study, using Wood's model, the lactation curve in Italian Heavy Draft horse (IHDH) mares, both for milk yield and composition. Interest in mare's milk has grown for use in human nutrition, as a substitute for human and cow milk for premature newborns and allergic children. For this study, 7 IHDH mares were used. Milk yield was evaluated from d 15 to 1 postpartum (every 15 d).

Wood's lactation model was used to describe milk yield, fat, protein, and lactose lactation curves in the first 1 d in milk (DIM), with a prediction to 2 DIM. Mean values recorded across the considered lactation period for milk yield and constituents were 161 kg of milkd, 118 g of fatkg, 154 g of proteinkg, and 692 g of lactosekg. The lactation curve showed a peak at 69 DIM, with a persistence index of 66. Fat (gkg) and protein (gkg) lactation curves decreased during the lactation period; instead, the lactose (gkg) curve increased from the first to the last DIM. The coefficient of determination values indicated a good model fit by Wood's model application to IHDH mare lactation.

Comparisons of infants living in different geographic regions and environmental contexts are needed to aid our understanding of evolutionarily-selected milk adaptations. However, the preservation of fecal samples from individuals in remote locales until they can be processed can be a challenge. Freeze-drying (lyophilization) offers a cost-effective way to preserve some biological samples for transport and analysis at a later date. Currently, it is unknown what, if any, biases are introduced into various analyses by the freeze-drying process. Here, we investigated how freeze-drying affected analysis of two relevant and intertwined aspects of infant fecal samples, marker gene amplicon sequencing of the bacterial community and the fecal oligosaccharide profile (undigested human milk oligosaccharides). No differences were discovered between the fecal oligosaccharide profiles of wet and freeze-dried samples.
