1. Estudo comparativo de parâmetros elétricos na absorção de substratos Na+/H+-dependentes em epitélio jejunal e ileal de coelho em câmaras de ussing / Comparative study of electric parameters in the substratum absorption Na+/H+-dependentes in epitélio jejunal and ileal de coelho in Chambers of Ussing
A cólera é uma doença que se tornou endêmica no Nordeste do Brasil após a pandemia iniciada no Peru em 1991. A toxina do Vibrio cholerae (TC) causa potente ação secretória no intestino delgado, podendo levar a desequilíbrio hidro-eletrolítico e choque hipovolêmico nos pacientes com cólera. Postulamos que a administração de substratos, tais como

2. Peptide hydrolase activities of the mucosa of human small intestine
Few studies have been published on peptide hydrolase activities of human small intestine mucosa. We developed methods to screen tissue extracts for such enzymes and to quantitate hydrolase activities for dipeptides containing the aromatic amino acid L-phenylalanine. The screening procedure indicated glycyl-L-proline hydrolase activity was reduced in biopsy s

3. Amino acid sequence requirements in the epitope recognized by the alpha-tubulin-specific rat monoclonal antibody YL 1/2.
We have characterized the epitope of the rat monoclonal antibody YL 1/2 in detail using synthetic peptides and several alpha-tubulin derivatives. The epitope seems to be provided by the linear sequence spanning the carboxy-terminal residues of tyrosinated alpha-tubulin. By competitive ELISA, dipeptides covering the carboxyl end could be antigenically recogni

4. Relevance of Peptide Uptake Systems to the Physiology and Virulence of Streptococcus agalactiae
Streptococcus agalactiae is a major cause of invasive infections in human newborns. To satisfy its growth requirements, S. agalactiae takes up 9 of the 20 proteinogenic amino acids from the environment. Defined S. agalactiae mutants in one or several of four putative peptide permease systems were constructed and tested for peptide uptake, growth in various m
