Feeding stimulates robust increases in muscle protein synthesis (MPS); however, ageing may alter the anabolic response to protein ingestion and the subsequent aminoacidaemia. With this as background, we aimed to determine in the present study the dose-response of MPS with the ingestion of isolated whey protein, with and without prior resistance exercise, in the elderly. For the purpose of this ...

TO THE EDITOR: Reitelseder et al. (4) are to be congratulated on their recent work. The use of intrinsically labeled proteins to study postexercise muscle protein accretion is a powerful tool, and the results are very interesting. I am concerned, however, by their interpretation that they have compared casein, as it exists in milk, to isolated whey when what they used was a not micellar casein ...

In recent years, the practice of bodybuilding has seen an increase in number fans gyms and, along with this increase, use dietary supplements, such as creatine and whey protein, been growing considerably by practitioners sport. addition, daily protein intake bodybuilders exceeds maximum recommendation, which, together these can lead to kidney and/or liver failure. The objective study was analyz...

BACKGROUND Lactobacillus bulgaricus LB6 is a bacterium which was selected in the commercial yoghurt with high angiotensin converting enzyme (ACE) inhibitory activity. Preparation of concentrated starter cultures via freeze drying is of practical importance to dairy and food industries. METHODS We optimized the optimal sugar alcohol and proteins for Lactobacillus bulgaricus LB6 during the proc...

Protein-rich supplements are used widely for the management of malnutrition in the elderly. We reported previously that the suppression of energy intake by whey protein is less in older than younger adults. The aim was to determine the effects of substitution, and adding of carbohydrate and fat to whey protein, on ad libitum energy intake from a buffet meal (180-210 min), gastric emptying (3D-u...

Epidemiological studies have suggested a relationship between diet and colon cancer incidence. Results from animal studies suggest that whey protein, but not casein protein, may provide protective effects against experimentally induced breast cancer in animals. In the current study, we investigated the effects of casein and whey diets on chemically induced colon cancer in male rats. Pregnant fe...

in this study, the effect of retentate and whey protein concentrate in different concentrations on the properties of low fat synbiotic yoghurt was studied. retentate samples containing different concentrations of the three concentrations ( 0.5 , 0.75 and 1 %) and whey protein concentrate ( 0.2 , 0.3 and 0.4 %) were prepared and characterized in terms of physicochemical , rheological and sensory...

1. Milk proteins of the Galapagos fur seal (Arctocephalus galapagoensis) were separated adequately into whey and casein fractions using bovine milk analysis methods. 2. In samples from days 5-30 of lactation 40% of the total proteins were whey and 60% caseins; in mid-lactation, day 150, 25% were whey and 75% casein proteins. 3. Electrophoretic and isoelectric focusing patterns of fur seal whey ...

The family of claudin proteins plays an important role in regulating the intestinal barrier by modulating the permeability of tight junctions. The impact of dietary protein on claudin biology has not been studied extensively. Whey proteins have been reported to improve intestinal barrier function, but their mechanism of action is not clear. Recent studies, however, have demonstrated increased i...

Multilayer plastic films provide a range of properties, which cannot be obtained from monolayer films but, at present, their recyclability is an open issue and should be improved. Research to date has shown the possibility of using whey protein as a layer material with the property of acting as an excellent barrier against oxygen and moisture, replacing petrochemical non-recyclable materials. T...
