Pulmonary macrophages (PM) exist in two general anatomical compartments in the lower respiratory tract: the alveolar space (alveolar macrophages, AM) and the interstitium (interstitial macrophages, IM). We determined the relative contribution that ma

This investigation was undertaken in order to examine the pulmonary inflammatory response to nitric oxide (NO) relative to that of nitrogen dioxide (NO2) when breathed at high concentrations for short durations. Croups of adult, male Fischer 344 rats

We demonstrate a high speed method to analyze the impact of self-quenching on fluorescence lifetimes in individual cells by phase-sensitive flow cytometry, using a model system consisting of FITC (fluorescein isothiocyanate) labeled antimouse Thy 1.2

Increases in cell proliferation are widely viewed as being of importance in carcinogenesis. We report that exposure of normal human lung fibroblasts to a low dose of alpha particles like those emitted by radon/radon progeny stimulates their prolifera

Spectral interference (overlap) from phagocytosed green-yellow (GY) microspheres in the flow cytometric, red fluorescence emission measurement channel causes errors in quantifying damaged/dead alveolar macrophages by uptake of propidium iodide.Partic

The primary source of interference in immunofluorescence measurements by flow cytometry is background autofluorescence.Using human lung fibroblasts (HLFs) as an autofluorescent cell model, unfixed HLFs and HLFs fixed in methanol, ethanol, formaldehyd

The pulmonary microenvironment is a primary target for alpha particles like those emitted by inhaled radon and its progeny. While exposure to alpha particles has recently been associated with the generation of extracellular and intracellular reactive

The protein kinase inhibitor staurosporine (Stsp) has been used extensively to study physiological functions, biochemical mechanisms, and cancer therapy. Using an HPLC assay for Stsp developed in our laboratory, we find that only 0.7% of Stsp remains

The mechanism(s) by which high-linear energy transfer a particles, like those emitted by inhaled radon and radon daughters, cause lung cancer has not been elucidated. Conceivably, DNA damage that is induced by a particles may be mediated by the metab

Epithelial cells along the conducting airways can be more or less continuously exposed to DNA-damaging agents, which should limit their proliferation by inducing cell cycle checkpoints. Yet, paradoxically, airway epithelial cells frequently show a hy
