The debut of Java technology in 1995 was a significant event for the computer security field. First, the claim that ”Java is secure” immediately attracted the intense scrutiny by the computer security research community. Numerous security bugs were later found (and fixed). Second, Java and the Internet once again highlighted the issue of mobile code security and the need for a comprehensive sol...

A competitive enzyme-linked immunosorbent assay (C-ELISA) which detects antibodies unique to rinderpest virus (RPV) has been developed. This test can differentiate antibodies against RPV and those against peste des petits ruminants virus. The recombinant RPV hemagglutinin (H)-protein C-ELISA (recH C-ELISA) is based on the ability of a well-characterized monoclonal antibody (MAb) produced with t...

The problem of integrating knowledge from multiple and heterogeneous sources is a fundamental issue in current information systems. In order to cope with this problem, the concept of mediator has been introduced as a software component providing intermediate services, linking data resources and application programs, and making transparent the heterogeneity of the underlying systems. In designin...

background : toxoplasmosis is a worldwide endemic disease. in congenitally infected infants and aids patients, toxoplasmosis causes high rates of morbidity and mortality. in these cases antibody detection is difficult; so detection of parasite or its components could be useful tool for early detection and following treatment of the infection. methods : sixty-three balb/c mice were injected intr...

Immunological diagnostic methods for Trypanosoma cruzi depend specifically on the presence of antibodies and parasitological methods lack sensitivity during the chronic and "indeterminate" stages of the disease. This study performed a serological survey of 1,033 subjects from 52 rural communities in 12 of the 18 municipalities in the state of Querétaro, Mexico. We detected anti-T. cruzi antibod...

ABST RACT Mycobacterium bovis (M. bovis) infection in cattle remains a major zoonotic and economic problem in many countries. In addition, M. bovis is an important pathogen of both man and animals. The standard diagnostic test for this disease is the intradermal tuberculin test, one of the oldest immunological tests still in widespread use. However, this test can lack both sensitivity and speci...
