13. Degradação de corantes reativos pelo sistema ferro metálico/peróxido de hidrogênio
In this work the degradation of aqueous solutions of reactive azo-dyes is reported using a combined reductive/advanced oxidative process based in the H2O2/zero-valent iron system. At optimized experimental conditions (pH 7, H2O2 100 mg L-1, iron 7 g L-1) and using a continuous system containing commercial iron wool, the process afforded almost total discolor

14. Seroprevalence of Hepatitis B virus infection among an afro-descendant community in Brazil
Furnas dos Dionísios is an Afro-Brazilian black community whose descendants were mainly fugitive slaves that established themselves in the State of Mato Grosso do Sul (MS), Brazil. The population is comprised mainly of low socioeconomic individuals who are engaged in agricultural activities. The objective of this study was to investigate the prevalence of h

15. Immunoglobulin G subclass response of localized juvenile periodontitis patients to Actinobacillus actinomycetemcomitans Y4 lipopolysaccharide.
Sera from patients with localized juvenile periodontitis (LJP) often contain markedly elevated immunoglobulin G (IgG) antibody titers to serospecific determinants of the lipopolysaccharide (LPS) from Actinobacillus actinomycetemcomitans. The objective of the present study was to define the subclass distribution of the IgG antibody response of LJP patients to

16. Qualitative evaluation of the reagin screen test.
After a preliminary study of 557 sera used as a procedural training exercise, the Reagin screen test (RST) for the macroscopic detection of reagin (as an aid to detecting syphilis) was qualitatively compared to the rapid plasma Reagin (RPR) (circle) card test and Veneral Disease Research Laboratory (VDRL) slide test on 435 random portions of sera using fluor

17. Immunogenic proteins of Trichomonas vaginalis as demonstrated by the immunoblot technique.
Fifteen clinical isolates of Trichomonas vaginalis were evaluated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis with transfer to nitrocellulose and by immunoblots probed with human sera. All T. vaginalis isolates showed similar banding patterns by Coomassie brilliant blue and silver staining of the electrophoresis gels and by amido black stain

18. Humoral antibody response against Bacteroides gingivalis-specific antigen recognized by monoclonal antibody in adult periodontal patients.
An antigen recognized by monoclonal antibody specific for Bacteroides gingivalis was purified in the presence of 0.5% (wt/vol) beta-octyl-glucoside by immunoadsorbent column chromatography. The purified antigen was homogeneous as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and silver staining, and the pattern of SDS-PAGE ag

19. Noninvasive assessment of vascular function in the posterior tibial artery of healthy humans
Flow-mediated dilation (FMD) measures the ability of an artery to relax in response to increases in blood velocity. FMD, primarily of the brachial artery, has been used as a noninvasive method of assessing vascular health. The purpose of this study was to assess FMD in the lower legs of humans. Six healthy subjects (27 ± 6 yrs) were tested. Doppler ultrasou

20. Protective immunogenicity of two synthetic peptides selected from the amino acid sequence of Bordetella pertussis toxin subunit S1.
Two peptides, corresponding to amino acids 1-17 and 169-186 of the amino acid sequence of pertussis toxin (PT) subunit S1, were synthesized and coupled to the diphtheria toxin cross-reactive mutant protein CRM 197 and evaluated for immunogenicity and protective capacity against PT challenge in vivo. The peptide-CRM conjugates induced high antibody titers aga

21. Transformation of Industrial Dyes by Manganese Peroxidases from Bjerkandera adusta and Pleurotus eryngii in a Manganese-Independent Reaction
We investigated the transformation of six industrial azo and phthalocyanine dyes by ligninolytic peroxidases from Bjerkandera adusta and other white rot fungi. The dyes were not oxidized or were oxidized very little by Phanerochaete chrysosporium manganese peroxidase (MnP) or by a chemically generated Mn3+-lactate complex. Lignin peroxidase (LiP) from B. adu
