13. Proteinograma do leite de vacas: padrões e variabilidade / Cow milk proteinogram: patterns and variability
The evaluation of the modifications in milk proteinogram is used as a diagnostic tool for bovine mastitis, once the inflammation of the mammary glands leads to changes in the concentration of milk proteic components, as well as the appearance of proteic components that are not elaborated in the milk secretion process. The technique of protein fractioning by

14. Genetic characterization of Aberdeen Angus cattle using molecular markers
Aberdeen Angus beef cattle from the Brazilian herd were studied genetically using restriction fragment length polymorphism (RFLP) of the kappa-casein - HinfI (CSN3 - HinfI), beta-lactoglobulin - HaeIII (LGB - HaeIII) and growth hormone AluI (GH- AluI) genes, as well as four microsatellites (TEXAN15, CSFM50, BM1224 and BM7160). The RFLP genotypes were determi

15. Analysis of genetic diversity and population structure in Argentine and Bolivian Creole cattle using five loci related to milk production
Data from five protein-coding loci related to dairy production were used to study the genetic diversity and population structure of Argentine and Bolivian Creole cattle breeds. Genomic DNA was extracted from blood samples of six Creole cattle breeds: Argentine (n = 230), Patagonian (n = 25); "Saavedreño" (n = 140), "Chaqueño Boliviano" (n = 30), "Yacumeño

16. Estudo de difração de raios-x a alta resolução da beta-lactoglobulina bovina
Beta-lactoglobulin (BLG), a very abundant protein found in several species of mammals belongs to the lipocalin family. Under physiological conditions, BLG is a dimmer of 162 aminoacids per monomer, with a molecular mass of approximately 18kDa in each subunit. Although BLG has important physicochemical properties, its biological function remains unclear. BLG

17. Multiple forms of mRNA encoding human pregnancy-associated endometrial alpha 2-globulin, a beta-lactoglobulin homologue.
Human pregnancy-associated endometrial alpha 2-globulin (alpha 2-PEG) is the major secretory protein product of the endometrium during embryo implantation and the first few weeks of pregnancy. It is a homologue of beta-lactoglobulin, a retinol binding protein, but unlike beta-lactoglobulin it is not found in the mammary gland. The cloning and sequencing of 3

18. Influence of preadsorbed milk proteins on adhesion of Listeria monocytogenes to hydrophobic and hydrophilic silica surfaces.
The adsorption of beta-lactoglobulin, bovine serum albumin, alpha-lactalbumin, and beta-casein for 8 h and beta-lactoglobulin and bovine serum albumin for 1 h at silanized silica surfaces of low and high hydrophobicity, followed by incubation in buffer and contact with Listeria monocytogenes, resulted in different numbers of cells adhered per unit of surface

19. Differences in the processes of beta-lactoglobulin cold and heat denaturations.
The changes in beta-lactoglobulin upon cold and heat denaturation were studied by scanning calorimetry, CD, and NMR spectroscopy. It is shown that, in the presence of urea, these processes of beta-lactoglobulin denaturation below and above 308 K are accompanied by different structural and thermodynamic changes. Analysis of the NOE spectra of beta-lactoglobul

20. Adhesion of Listeria monocytogenes to silica surfaces after sequential and competitive adsorption of bovine serum albumin and beta-lactoglobulin.
Adsorbed bovine serum albumin was resistant to exchange with beta-lactoglobulin, and when albumin was adsorbed from a mixture, its surface concentration increased with time. The passivating character of adsorbed albumin and its resistance to desorption were consistent with the level of Listeria monocytogenes adhesion evoked by albumin-containing protein film

24. Difference between bacterial and food antigens in mucosal immunogenicity.
The mucosa-associated lymphoid tissue may deviate from its systemic counterpart in being able to discriminate between microbial and nonmicrobial antigens. To study this, the systemic and mucosal antibody responses to bacterial and food antigens were followed in parallel in female rats during two pregnancies and lactation periods. Germfree rats were monocolon
