INTRODUCTION The Total Antioxidant Capacity (TAC) of human milk reflects the concentration and the activity of many components which prevent oxidative degradation of fats and proteins. This study compares the effectiveness of ABTS and DPPH tests with regard to the recovery, precision and sensitivity (detection and quantification limit) of (TAC) values in human milk. MATERIAL AND METHODS TAC v...

In mammary epithelial cells, milk lipids and proteins are synthesised in the same compartment, the endoplasmic reticulum. Lipids, carried through the cytoplasm, associate with the apical membrane which then pinches off and releases the lipid globule. Proteins, carried through membrane compartments are released in the lumen after fusion of secretory vesicles with the apical membrane. These proce...

The active ingredient, or liver-protecting compound in milk thistle is known as silymarin. This substance, which actually consists of a group of compounds called flavonolignands, helps repair liver cells damaged by alcohol and other toxic substances by stimulating protein synthesis. By changing the outside layer of liver cells, it also prevents certain toxins from getting inside. Silymarin also...

Female crossbred swine (Chester White x Landrace x Large White x Yorkshire) selected for three generations for low (L, n = 24) or high (H, n = 26) serum cholesterol at 8 wk of age were milked at d 20 or 21 of their first lactation to measure cholesterol, fat, lactose, protein, and ash concentrations. A contemporary, unselected control (C) group from the same original population (third lactation...
