A "Pap" test for men? Male urethral smears as screening tool for detecting subclinical human papillomavirus infection.
We have explored the potential of using immunoperoxidase staining and in situ DNA hybridization techniques to detect the HPV common antigen and HPV DNA (subtypes 6/11 and 16/18) in urethral smears… Expand
Oxygen free radicals as inducers of heat shock protein synthesis in cultured human neuroblastoma cells: Relevance to neurodegenerative disease
SummaryWe studied heat shock protein (HSP) synthesis by cultured human neuroblastoma cells in response to either hyperthermia or high levels of superoxide anion (oxygen free radical). Both treatment… Expand
Immunocytochemical detection of the 70-kd heat shock protein in alcoholic liver disease.
Exposure of cells to physical (eg, heat) or chemical (eg, alcohol) stress results in increased synthesis of a set of highly conserved polypeptides termed heat shock proteins (HSPs), among which the… Expand
Hydrogen peroxide and reoxygenation cause prostaglandin-mediated contraction of human placental arteries and veins.
Objective: Because our previous studies in several vascular preparations suggest that posthypoxic reoxygenation elicits tone responses by generation of hydrogen peroxide we compared the actions of… Expand
Lack of crucial role of mast cells in pathogenesis of experimental colitis in mice
Mast cell alterations have been implicated in the pathogenesis of chronic ulcerative colitis (UC). We studied the effect of mast cell deficiency on the severity of inflammation in a murine model of… Expand

The origin of the various components of senile plaques in Alzheimer's disease (AD) continues to be a focus of intense research scrutiny. Lysosomal enzyme activity within the plaques is of particular… Expand
Concurrent neuroborreliosis and Alzheimer's disease: analysis of the evidence.
Several recent reports have claimed a possible association between Borrelia burgdorferi infection and Alzheimer's disease (AD). Herein, we describe our search for additional evidence of… Expand

ABSTRACT We report the first case of mixed pulmonary infection with Strongyloides stercoralis and Blastomyces dermatitidis. Histopathology from the lung biopsy showed structures consistent with B.… Expand
Heat shock protein response in alcoholic liver disease
Exposure of cells to various (physical and chemical) forms of stress results in increased synthesis of a set of highly conserved polypeptides termed heat shock proteins (HSPs), among which the 85 kd… Expand
