| ABSTRACT The strangles is an infectious disease that affects horses from all ages and causes important economic losses in the equine-related business. The aim of this work was to evaluate the immunogenicity of the recombinant M protein from Streptococcus equi (rSeM) co-administered with the recombinant heat-labile enterotoxin B subunit from Escherichia coli (rLTB) in mice and horses. A total of 72 female Balb-c mice were divided into eight groups and 18 horses were divided into six groups. The animals were inoculated by intramuscular (IM) or intranasal (IN) routes with different treatments of rSeM, rLTB and/or Al(OH)3. The results obtained in both species, independent of administration routes, demonstrated that rSeM + rLTB had higher levels of specific... |

| RESUMO Este trabalho relata o desenvolvimento e a avaliação de um ensaio imunoenzimático (ELISA) como ferramenta auxiliar no controle da adenite equina. Foi avaliada a presença de anticorpos anti-Streptococcus equi subsp. equi em equinos com doença clínica de garrotilho, portadores assintomáticos e potros vacinados. Equinos doentes demonstraram absorbâncias médias superiores (P<0,05) às médias observadas nas demais categorias examinadas. Equinos portadores assintomáticos apresentaram valores médios de absorbância superiores (P<0,05) aos animais com cultura negativa. Logo após a vacinação, potros apresentaram elevação nos níveis de anticorpos, seguida de um decréscimo nos níveis 90 dias após a segunda vacinação. O “Cell ELISA” foi eficiente para a... |

| Hepatocellular carcinoma (HCC) is the third highest cause of cancer death worldwide. In general, the disease is diagnosed at an advanced stage when potentially curative therapies are no longer feasible. For this reason, it is very important to develop new therapeutic approaches. Retinoic acid (RA) is a natural derivative of vitamin A that regulates important biological processes including cell proliferation and differentiation. In vitro studies have shown that RA is effective in inhibiting growth of HCC cells; however, responsiveness to treatment varies among different HCC cell lines. The objective of the present study was to determine if the combined use of RA (0.1 µM) and cAMP (1 mM), an important second messenger, improves the responsiveness of HCC... |
