Dietary lipids can modify the clinical behavior and morphological features of experimental breast tumors. We previously demonstrated that a high corn oil diet has a tumor-enhancing effect in 7,12-dimethylbenz(alpha)anthracene (DMBA)-induced rat mammary adenocarcinomas, whereas a high olive oil diet acts as a negative modulator of carcinogenesis. In this study, we investigated whether these high...

In this study, different adhesives manufactured by using various casein powders (micellar casein, αS-, β- and ĸ-casein fractions, sodium caseinate calcium caseinate) were investigated for their properties potential application in the food industry. Casein-based sources of caseins produced differences adhesive strength determined. For isolation methods selective solubility, precipitation a decan...

It has been shown at the California Agricultural Experiment Station by Thompson and Voorhies (7) ^ and by Hughes (2) that barley, when fed as the only source of protein, does not produce optimum growth in pigs. Protein-rich concentrates like fish meal and tankage or dairy byproducts when used as supplements to barley, produce more rapid growth. Such concentrates, however, contain other nutrient...

We examined 62 strains and 21 trade starter cultures from the collection of LB Bulgaricum PLC for proteolytic and antimicrobial activity of lactic acid bacteria (LAB) grown in goat milk. The aim of this study was to investigate the fermentation of caseins, α-lactalbumin and β-lactoglobulin by LAB, using the o-phthaldialdehyde (OPA) spectrophotometric assay and sodium dodecyl sulphate polyacryla...

The first months of life correspond to a key period in human life where dramatic physiological changes (establishment of microbiota, development of the immune system, etc.) occur. In order to better control these changes it is necessary to understand the behaviour of food in the gastrointestinal tract of the newborn. Infant formula is the only food for the newborn when breast-feeding is impossi...

In the mammary gland the induction and maintenance of differentiation are dependent on both lactogenic hormones and the extracellular matrix (ECM). Since mammary epithelial cells differentiate on a basement membrane in vivo we have examined the effects of basement membrane components on the expression of milk protein genes in primary rat mammary cultures. We examined the effects of a basement m...
