Phosphorylated osteopontin (OPN) inhibits hydroxyapatite crystal formation and growth, and bone alkaline phosphatase (BALP) promotes extracellular mineralization via the release of inorganic phosphate from the mineralization inhibitor inorganic pyrophosphate (PPi). Tartrate-resistant acid phosphatase (TRAP), produced by osteoclasts, osteoblasts, and osteocytes, exhibits potent phosphatase activity towards OPN; however, its potential capacity as a regulator of mineralization has not previously been addressed...

Exosomes are membranous vesicles found in biological fluids with important functions. However, milk-derived exosome proteins from humans and bovines have not been studied in detail. The advanced iTRAQ proteomic approach was used to analyze milk-derived exosomes in human and bovine colostrum and mature milk samples. A total of 920 milk exosome proteins were identified and quantified. Among these, 575 differentially expressed exosome proteins (P<0.05) were found. Multivariate analysis, gene ontology (GO) annotation and the KEGG pathway were used to interpret the identified proteins...

The rheological properties of acid-induced coagulation of camel and cow milk gels following the addition of calcium chloride (CaCl2) and hydrogen phosphate dehydrate (Na2HPO4*2H2O) were investigated using a dynamic low amplitude oscillatory rheology. For a considered condition, the final values of storage modulus (G') and loss modulus (G″) of camel milk gels were significantly lower than those of cow milk gels. The increase of the added CaCl2 levels improved significantly the gelation properties of camel and cow milk gels, since a reduction in the gelation time and an increase in the gel firmness were observed...

The spinel-type magnetic manganese ferrite (MnFe2O4) microspheres synthesized by simple solvothermal method were used as a novel adsorbent for selective enrichment and effective isolation of phosphopeptides. The uniform MnFe2O4 magnetic affinity microspheres (MAMSs) had a narrow particle size distribution between 250 and 260nm, and displayed superparamagnetism with a saturation magnetization value of 67.0emu/g. Comprehensively, the possible formation mechanism of MnFe2O4 microspheres with ferric and manganous sources as dual precursors was elucidated by comparison with those of Fe3O4 nanoparticles and MnOOH nanosheets respectively with either ferric or manganous source as single precursor...

Colloidal gold and Eu(3+) -doped fluorescent microspheres were applied as labels to develop the immunochromatographic strips for detecting melamine in milk. Under the optimized condition, the visual detection limit of colloidal gold-immunochromatographic test strip (ICTS) was 150 μg/L of melamine in phosphate-buffered saline (PBS), although the visual detection limit of fluorescent nanoparticles (FN)-ICTS was 75 μg/L in PBS. As thermal acceleration test, FN-ICTS could be stored at 37 °C for at least 11 d before sample testing, but the color of the lines on colloidal gold-ICTS faded away after 7-d storage...

The high prolificacy of modern hybrid sows has increased the mean litter size during the last decades. However, rearing large litters is challenging and has increased the use of alternative management strategies such as euthanasia of weak piglets, cross-fostering, supplementing piglets with milk, split-nursing and split-weaning. The latter includes artificial rearing on brooders where piglets have ad libitum access to milk replacer. The effect of this artificial rearing on the immune system of the piglet is the subject of various studies...

Currently, great challenges to top-down phosphoproteomics lie in the selective enrichment of intact phosphoproteins from complex biological samples. Herein, we developed a facile approach for synthesis of Ti(4+) -immobilized affinity silica nanoparticles and applied them to the selective separation and enrichment of intact phosphoproteins based upon the principle of metal(IV) phosphate/phosphonate chemistry. The as-prepared affinity materials exhibited high selectivity and adsorption capacities for model phosphoproteins (328...

Grafting copolymerization, especially "grafting from" approach, has attracted a great attention for the preparation of cellulose-based materials with various functionalities. In this study, a novel phosphate group-containing cotton fiber-based material, CF-NH2-AZO-p(VPA-x), was successfully synthesized by a "grafting from" radical polymerization approach using vinyl phosphonic acid (VPA) as monomer. The phosphate group content of CF-NH2-AZO-p(VPA-x) could be easily regulated by adjusting the concentration of VPA monomer...

BACKGROUND: Phosphorus (P) levels in refeeding diets are very important as undernourished children are at risk of hypophosphatemia during refeeding. For this reason, conventional corn-soy-blends (CSB) have been reformulated by the World Food Programme to obtain a mono-calcium-phosphate fortified product (CSB+) and a product further fortified with skim milk powder (CBS++). METHODS: Using a piglet model of undernourished children, we hypothesized that feeding of CSB+, CSB++ or CSB+ with added whey permeate (CSB+/wp) would help to prevent refeeding hypophosphatemia...

INTRODUCTION: Mycobacterium bovis has a broad host range, and it is the principal agent responsible for tuberculosis (TB) in bovine, domestic and wild mammals. M. bovis also infects human, causing zoonotic TB through ingestion, inhalation and, less frequently by contact with mucous membranes and broken skin. Zoonotic TB was formerly an endemic disease, usually transmitted to man by consumption of raw cow's milk. It is indistinguishable clinically or pathologically from TB caused by M...

Blueberry proanthocyanidins (B-PAC) are known to decrease titers of human norovirus surrogates in vitro. The application of B-PAC as therapeutic or preventive options against foodborne viral illness needs to be determined using model foods and simulated gastric conditions in vitro. The objective of this study was to evaluate the antiviral effect of B-PAC in model foods (apple juice (AJ) and 2% reduced fat milk) and simulated gastrointestinal fluids against cultivable human norovirus surrogates (feline calicivirus; FCV-F9 and murine norovirus; MNV-1) over 24 h at 37 °C...

Ultrafiltration (UF) of skimmed milk altered the composition of UF retentate and decreased the heat stability. Heat stability further reduced upon its subsequent homogenization or diafiltration. Poor heat stability of UF retentate restricts its processing at elevated temperatures. Therefore, this study was aimed to investigate the effect of protein concentration, homogenization and addition of stabilizing salts on the heat stability and rheological properties of UF retentates. Changes in the heat stability of fivefold homogenized UF retentate (5× HUFR) was studied in the pH range of 6...

This 2-period crossover study investigated the effect of calcium-phosphate-osteopontin particles on biofilm formation and pH in 48-h biofilms grown in situ. Bovine milk osteopontin is a highly phosphorylated glycoprotein that has been shown to interfere with bacterial adhesion to salivary-coated surfaces. Calcium-phosphate-osteopontin particles have been shown to reduce biofilm formation and pH drops in a 5-species laboratory model of dental biofilm without affecting bacterial viability. Here, smooth surface biofilms from 10 individuals were treated ex vivo 6 times/day for 30 min with either calcium-phosphate-osteopontin particles or sterile saline...
