Bilateral bronchoalveolar lavage (BAL) was carried out in right middle and left upper lobes of 22 nonsmoking females suffering from progressive systemic sclerosis in order to assess interlobar differences and functional correlation of the BAL composition. The patients' age ranged from 20 to 66 years, and the mean disease duration was 10.4 years. The most(More)
An immunoperoxidase method, using a monoclonal antibody which recognizes 4-aminobiphenyl (4-ABP)-DNA adducts, was developed for the detection and quantitation of DNA damage in bladder tissue and applied to stored paraffin blocks of transurethral resection specimens of 46 patients with T1 bladder cancer. Mean relative staining intensity for 4-ABP-DNA adducts(More)
OBJECTIVES The aim of this study was to detect polycyclic aromatic hydrocarbon-DNA (PAH-DNA) adducts in single cervical cells collected during a routine Papanicolaou smear and to relate this carcinogen exposure dose marker to smoking habit. METHODS An immunohistochemical assay, using a polyclonal antiserum raised against benzo[a]pyrene diol epoxide-DNA(More)
Recent studies indicate that the functions of several genes that control the cell cycle are altered during the carcinogenic process and that these changes perturb both cell proliferation and genomic stability, thus promoting cell transformation and enhancing the process of tumor progression. The purpose of this paper is to review current information on the(More)
PURPOSE Best chances of a cure from colorectal cancer are obtained before metastatic spread. Lack of specific tests allowing early diagnosis of the tumor accounts for investigation of gene alterations involved in carcinogenesis by a noninvasive method. In the present study, K-ras codons 12 and 13 mutations were studied in neoplastic cells shed from the(More)
p53 overexpression was studied by immunohistochemistry in 96 consecutive colorectal cancer patients, subdividing positive specimens according to two staining patterns: cytoplasmic or nuclear. Forty-seven per cent of the cases were p53 positive, a significant correlation being found with Dukes' stage (P = 0.0036). A prevalence of nuclear staining was(More)
Increasing experimental evidence demonstrates that malignant transformation is associated with changes in the repertoire of expression of the integrin family of molecules, which mediate cell-matrix and cell-cell interactions. We have analyzed immunohistochemically and immunochemically the expression of VLA-3 integrin and its known ligands, namely, laminin(More)
