Clinicopathologic correlations were explored in 79 patients at high risk for human immunodeficiency virus (HIV) infection who had lymph node biopsy for persistent lymphadenopathies and were followed for intervals of up to 7.2 years. Three histologic patterns, follicular hyperplasia with cytolysis (A), follicular involution with hypervascularity (C), and a(More)
A Monte Carlo simulation is incorporated into a risk assessment for trichloroethylene (TCE) using physiologically-based pharmacokinetic (PBPK) modeling coupled with the linearized multistage model to derive human carcinogenic risk extrapolations. The Monte Carlo technique incorporates physiological parameter variability to produce a statistically derived(More)
This study determined the prevalence, cellular localization, and content of human immunodeficiency virus (HIV)-associated antigens in intestinal mucosa from HIV-infected subjects. Studies were performed in 168 subjects with gastrointestinal, nutritional, or proctologic complaints, and HIV-seronegative controls. The polymerase chain-reaction technique, which(More)
The testes and prostates of 14 patients with acquired immune deficiency syndrome (AIDS) for whom autopsies were performed were examined for the presence of human immunodeficiency virus (HIV) and the pathologic alterations seen in AIDS. Histologically, the testes contained peritubular fibrosis and variable spermatogenic arrest, which were inconsistent with(More)
Rectal mucosal biopsy specimens from 75 human immunodeficiency virus (HIV)-seropositive and 16 HIV-seronegative subjects were examined. The histopathologic changes were correlated with immunoperoxidase staining for UCHL-1 and HIV core protein p24, quantitative p24 enzyme-linked immunosorbent assay (ELISA) assay in homogenized rectal tissue and serum, and a(More)
Human lymphotropic retroviruses lymphadenopathy-associated virus/human T lymphoma virus III have been recently implicated in the pathogenesis of the acquired immune deficiency syndrome (AIDS). The mechanisms leading to the complex immune deregulations of this disease, however, are still largely unknown. To investigate the possible presence of(More)
We present our experience with immunophenotypic characteristics of benign and malignant myeloid populations, with emphasis on differential diagnosis especially between eosinophils, dysplastic granulocytes, neoplastic promyelocytes, and monocytes. Eosinophils are characterized by bright CD45, high side scatter (SSC), very low forward scatter (FSC), positive(More)
The presence of antilymphocyte antibody (ALA) in patients with the acquired immunodeficiency syndrome (AIDS), identified in a previous study, was confirmed by testing a population of 200 patients with AIDS. Of these, 88% had significant levels of ALA vs only 8% of a control group of patients with non-AIDS-related diseases. In a prospective study, the levels(More)
