Chum salmon skin gelatin, de-isoflavoned soy protein, and casein were hydrolyzed at two degrees of hydrolysis. Genistein, the prepared hydrolysates, and genistein-hydrolysate combinations were assessed for their proliferative and anti-apoptotic effects on human osteoblasts (hFOB 1.19) to clarify potential cooperative effects between genistein and these hydrolysates in these two activities. Geni...

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 ...

The present study aimed at establishing a complete plant regeneration protocol for Didymopanax morototoni (matchwood), a native Brazilian forest species. Four types of explants (root, shoot, node, and cotyledonary leaves) were obtained from in vitro germinated seeds. In the first step, woody plant medium (WPM) with casein hydrolysate (250 mgL-1 ) and 2,4-D (1.0 and 5.0 mgL-1) were used combined...

Sir: Resistant of tumor cells to multiple cytotoxic drugs is a major impediment to cancer chemotherapy. Multidrug-resistance (MDR) is characterized by decreased cellular sensitivity to anticancer agents due to the increased expression of a membrane glycoprotein with a MWof approximately 170 kd, termed P-glycoprotein1}. It is well known that colchicine-resistance cells have simultaneously acquir...

This study examined whether a carbohydrate + casein hydrolysate (CHO+ProH) beverage improved time-trial performance vs. a CHO beverage delivering approximately 60 g CHO/hr. Markers of muscle disruption and recovery were also assessed. Thirteen male cyclists (VO2peak = 60.8 +/- 1.6 ml . kg-1 . min-1) completed 2 computer-simulated 60-km time trials consisting of 3 laps of a 20-km course concludi...

When amino acids or ammonia are added to plant systems, the effects on the development of nitrate-dependent nitrate reductase activity are variable. In addition, amino acids added singly or as casein hydrolysate may not support a normal growth. A physiologically correct mixture of amino acids, one similar in composition to amino acids released by the endosperm, has been shown to support normal ...

This study examined the effects of corn gluten (CG) and its hydrolysate consumptions on weight reduction in rats fed a high-fat diet. Eight-month-old male Sprague-Dawley rats (n=40) were fed a high-fat diet (40% calorie as fat) for 4 weeks. They were then randomly divided into four groups and fed the isocaloric diets with different protein sources for 8 weeks. The protein sources were casein (c...

In a double blind study, 40 infants with cows' milk intolerance of various causes were randomised to receive a nutritionally complete formula in which nitrogen was supplied either as whey hydrolysate or amino acids. The median age of infants was 10 weeks (range 36 weeks' gestation to 108 weeks' postnatal age). After a median follow up period of 25 weeks there was no significant difference in di...

Whey protein hydrolysate (WPH) intake has shown to increase HSP70 expression. The aim of the present study was to investigate whether WPH intake would also influences HSP90, HSP60 and HSP25 expression, as well as associated parameters. Forty-eight male Wistar rats were divided into sedentary (unstressed) and exercised (stressed) groups, and were fed with three different sources of protein: whey...
