1. Prevalence by HPV and squamous intraepithelial lesions in pregnant women / PrevalÃncia de HPH e lesÃes intraepiteliais escamosas em gestantes
This work studies the prevalence (cross sectional) on infection by HPV in uterine cervical of pregnant women evaluating the subgroups of HPV more prevalents and the association in relation to the development of squamous intraepithelial lesions. The methodology was constituted of questionary applied to 272 pregnant women independent of pregnant age and of bei

2. Human Papillomavirus and Cervical Cancer
Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whet

3. Cytologic assessment of nuclear and cytoplasmic O-linked N-acetylglucosamine distribution by using anti-streptococcal monoclonal antibodies.
Recent studies have demonstrated the existence of single O-linked N-acetylglucosamine (O-GlcNAc) residues on cytoplasmic and nuclear glycoproteins. Labeled lectin and enzymatic techniques have been used to identify O-GlcNAc-bearing proteins, but no antibodies generally reactive with such O-linked GlcNAc moieties have been described. We have previously charac

4. Immunodiagnosis of human malignancy.
Definition of normal cell membrane antigens using immunologic techniques has permitted investigators to distinguish normal cells from malignant cells. Malignant cells express fetal antigens in concentrations different from normal mature cells. Mutant cells express differentiation as well as those antigens reflecting the altered cell genome. Normal cells can

5. Detection of infection or infectious agents by use of cytologic and histologic stains.
A wide variety of stains are useful for detection of different organisms or, for viruses, the cytopathologic changes they induce, in smears prepared directly from clinical specimens and in tissue sections. Other types of stains, such as hematoxylin and eosin, are used routinely to stain tissue sections and are most valuable for assessing the immunologic resp

6. Comparison of PCR and standard cytological staining for detection of Pneumocystis carinii from respiratory specimens from patients with or at high risk for infection by human immunodeficiency virus.
The detection of Pneumocystis carinii DNA by PCR was compared with routine cytologic staining techniques (CYT). A total of 284 clinical respiratory specimens, including 137 bronchoalveolar lavage (BAL), 63 bronchoalveolar washing, 63 sputum, and 21 induced sputum samples, obtained from patients with or at high risk for human immunodeficiency virus infection
