STATEMENT OF PROBLEM Dental fractures can occur in endodontically treated teeth restored with glass fiber reinforced posts and cast gold posts. PURPOSE The objective of this study was to record the fracture strength of endodontically treated teeth restored with glass fiber reinforced or cast gold post and cores cemented with 3 cements. MATERIAL AND(More)
The protective immune responses against rubella virus (RV) are related to its neutralizing epitopes, an issue that is important to consider when assessing the immune status of patients with remote infection. In the present paper, we compare the antibodies detected by a synthetic-peptide-based enzyme immunoassay (EIA) with antibodies detected by the(More)
The serological diagnosis of primary postnatal rubella infection is based on detection of rubella-virus-specific IgM antibody or a four-fold rise in rubella-specific IgG antibody. Although there are several different methods of enzyme immunoassays that are commercially available, the cost benefit evaluation makes them impractical for use in developing(More)
BACKGROUND AND OBJECTIVES Rubella virus (RV) produces a subtle and slow-developing cytopathic effect in Vero cells that is difficult to recognize, especially at low multiplicities of infection. In order to facilitate the detection of RV in cell culture, we standardized a low-pH virus-mediated cell-fusion assay. STUDY DESIGN The incubation periods,(More)
We studied the presence of a neutralizing epitope of rubella virus (RV) in locally circulating strains in Cordoba, Argentina, using binding by the monoclonal antibody (MAb) H3. This epitope is contained in a sequence of the E1 glycoprotein (E1208-239) represented by the synthetic peptide SP15. H3 MAb showed specific binding to SP15 by enzyme-linked(More)
Congenital rubella syndrome (CRS) could be prevented if young women knew their immune status before pregnancy, contributing in this way to decrease the birth morbidity rate due to CRS among the children. Our objective was to optimize the detection of rubella virus-antibodies by HAI, using an easier and safer method to collect samples of big populations. One(More)
There is, apparently, only one serological type of rubella virus (RV) in the population, although several isolates exist with different characteristics. Some authors failed to detect significant differences among RV strains by neutralization, hemagglutination inhibition, and enzyme immunoassay using polyclonal and monoclonal antibodies, but differences in(More)
We studied the presence of C. trachomatis-specific IgG and IgM in adults and newborns, respectively, and attempted isolation of the bacteria in cell culture. The determination of antibodies was carried out by an IFA on C. trachomatis infected (L2 434/Bu serotype) McCoy cells, cultured in 24-well plastic plates. We found C. trachomatis-specific IgG in 27% of(More)
