A serious complication seen in critically ill patients is the solidification of enteral nutrition causing gastrointestinal obstruction. It has been suggested that enteral nutrition enriched with insoluble fibers may increase the risk of this complication. Therefore, we investigate the effect of soluble and insoluble dietary fibers on the coagulation of a casein-based enteral nutrition in an art...

Maillard reaction products (MRPs) were prepared from a casein–glucose reaction and ultrafiltrated to provide six fractions. The high molecular weight glycated proteins (melanoprotein) were further...

Previous studies from our laboratory have demonstrated that hormone-dependent 7,12-dimethylbenz(a)anthracene-induced rat mammary carcinomas possess only a limited ability to syn thesize the mammary gland-specific milk proteins, and this expression of normal differentiated function is limited to a small subpopulation of tumor cells (S. C. Supowit and J. M. Rosen, Cancer Res., 42: 1355-1360, 1982...

Antisera to the mouse milk factor (F), containing up to 0.5 mg. of antibody nitrogen per ml. are readily obtainable in rabbits, especially when adjuvants are added to the antigen. Quantitative data on the anti-F content of the sera are given, also on the total nitrogen precipitated by the non-casein fraction of C57 mouse milk which does not contain F. The antisera were also absorbed with casein...

1. Columns of Sephadex G-25 have been used for the preliminary fractionation of tryptic digests of casein. 2. Fractions from Sephadex columns have been examined for their ability to stimulate the growth of a strain of Streptococcus equi8imili8. Maximum stimulatory activity appeared to be localized in a fairly narrow region of the total peptide material. 3. Further fractionation of peptides deri...

This study investigates the effects of salmon peptide fractions, generated using different enzymatic hydrolyzation methods, on hepatic lipid metabolism. Four groups of mice were fed a high-fat diet with 20% casein (control group) or 15% casein and 5% of peptide fractions (treatment groups E1, E2 and E4) for 6weeks. Weight gain was reduced in mice fed E1 and E4-diets compared to control, despite...

This study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (Camelus dromedarius). Milk samples representing the wet and dry seasons were analyzed for total solids (TS), fat (F), solids-non-fat (SNF), ash, crude protein (CP), nitrogen soluble at pH 4.6 (SN), mineral content (MC) and casein fraction (CnF). Camel milk had higher (P

Caseinomacropeptide (CMP) is a heterogeneous C-terminal fragment (residues 106 to 169) of bovine milk kappa-casein composed of glycosylated and phosphorylated forms of different genetic variants. We have demonstrated that CMP has growth-inhibitory activity against the oral opportunistic pathogens Streptococcus mutans and Porphyromonas gingivalis and against Escherichia coli. CMP was fractionate...

Calves were fed five different test meals: whole milk, skim milk, 3% whole casein solution, 3% whole casein in simulated milk ultrafiltrate, and whey. The digesta leaving the abomasum before feeding and during the first 7 postprandial hours were collected by fractions. After precipitation with 12% TCA, the amino acid compositions of the sediments and the supernatants were determined and compare...
