The AIN-76A diet causes fatty liver in rodents when fed for long periods of time. The aimof this study was to utilize fatty acid analysis and transcriptomics to investigate the effects of different fat sources in the AIN-76A diet on tissue lipid profiles and gene expression in male, weanling Fischer-344 rats. Animals were fed isocaloric diets that differed only in the fat source: (1) corn oil (CO) (2) anhydrous milk fat (AMF), and (3) AMF supplemented with 10 % phospholipids from the milk fat globule membrane (AMFMFGM). There were no differences in food intake, body weight, growth rate, or body fat ...

Plant-based oral vaccines are a promising emergent technology that could help alleviate disease burden worldwide by providing a low-cost, heat-stable, oral alternative to parenterally administered commercial vaccines. Here, we describe high-level accumulation of the hepatitis B surface antigen (HBsAg) at a mean concentration of 0.51%TSP in maize T1 seeds using an improved version of the globulin1 promoter. This concentration is more than fourfold higher than any previously reported lines. HBsAg expressed in maize seeds was extremely heat stable, tolerating temperatures up to 55 °C for 1 month without degradation. Optimal heat stability was achieved after oil extraction of ...

Effect Of Nacl Addition During Diafiltration On The Solubility, Hydrophobicity, And Disulfide Bonds Of 80% Milk Protein Concentrate Powder, X. Y. Mao, P. S. Tong, S. Gualco, S. Vink Jul 2012

Effect Of Nacl Addition During Diafiltration On The Solubility, Hydrophobicity, And Disulfide Bonds Of 80% Milk Protein Concentrate Powder, X. Y. Mao, P. S. Tong, S. Gualco, S. Vink

Dairy Science

We investigated the surface hydrophobicity index based on different fluorescence probes [1-anilinonaphthalene-8-sulfonic acid (ANS) and 6-propionyl-2-(N,N-dimethylamino)-naphthalene (PRODAN)], free sulfhydryl and disulfide bond contents, and particle size of 80% milk protein concentrate (MPC80) powders prepared by adding various amounts of NaCl (0, 50, 100, and 150 mM) during the diafiltration process. The solubility of MPC80 powder was not strictly related to surface hydrophobicity. The MPC80 powder obtained by addition of 150 mM NaCl during diafiltration had the highest solubility but also the highest ANS-based surface hydrophobicity, the lowest PRODAN-based surface hydrophobicity, and the least aggregate ...
