We investigated the effects of high protein intake on host resistance to Paracoccidioides brasiliensis. Two-d fasted mice were infected with P. brasiliensis and refed on diets with three different levels (54%, 20%, and 5%) of casein. The mice refed the 54% casein diet showed reduced antifungal activity in the spleen and liver as compared with the mice refed the 5% or the 20% casein diet. After ...

Various species of rodents and lagomorphs were used in bioassays to determine the effectiveness of protein hydrolysates (specifically hydrolyzed casein and gelatin) as herbivore repellents. Mixed sex groups of captive rabbits, pocket gophers, voles, and mountain beavers were offered hydrolyzed casein or gelatin test diets in single-choice tests following a training period with a hydrolysate-fre...

Adrenal delta5-3beta-hydroxysteroid dehydrogenase (delta5-3beta-HSD) activity and serum corticosterone level were significantly higher in rats fed with 5% casein or 4% albumin diets after 1 hr of ether anaesthetic stress as compared to the controls, 5% casein and 20% casein (equivalent to 4% albumin) respectively. Ether anaesthesia to 20% casein fed rats caused no change in adrenal delta5-3beta...

BACKGROUND Hepatitis C is a global health concern that represents a major cause of liver disease and socioeconomic burden. Currently, there is no vaccine that protects against this infection or drug that treats it effectively. The current treatment for hepatitis C virus (HCV) infection does not produce a sustained virologic response. Therefore,discovery and identification of a new drug for HCV ...

Casein is one of the milk proteins which have unique characteristic, it called assembly. Assembly casein can interact with or others to form micelle nanoparticle. The nano size accelerate process absorption into body, making suitable as a delivery system nutraceutical food. It happen appropriate temperature. According statement, this research aims determine best temperature for reassembling phe...

Besides its nutritional value, bovine beta-casein is a source of bioactive peptides called betacasomorphins produced during digestion of raw or processed milk. It was shown that the betacasomorphin 7 originates only from beta-casein variants A1 or B and may be a significant risk factor in human ischemic heart disease, arteriosclerosis, type I diabetes and sudden infant death syndrome. In this s...

We used polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) analysis to screen the most frequent variants (A, B, C, and E) found in the bovine kappa-casein gene. The PCR products (453 bp) were heat-denatured, loaded onto nondenaturing polyacrylamide gels, and silver-stained. Each variant yielded patterns clearly distinguishable from the others. Optimal conditions for th...

The present investigation was aimed at studying 1.26 kb αS2-casein promoter gene in αS2casein gene locus between the three buffalo breeds. αS2 -casein promoter gene was amplifi ed by PCR using oligonucleotide primers standardized for Bos taurus species. The sizes of the amplifi cation products were similar. PCR amplicons are subjected to restriction digestion by the enzyme Eco RV, only an intac...

Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...

Twenty-five wether lambs (34 +/- 0.9 kg) fitted with ruminal and abomasal infusion catheters were used in a completely randomized design to determine the effects of differing proportions of ruminal and abomasal casein infusion on N balance in lambs fed a high-concentrate diet (85% corn grain, 1.6% N; DM basis) for ad libitum intake. Wethers were infused with 0 (control) or 10.4 g/d of N from ca...
