Fas (CD95, APO-1) is regarded as the prototypical cell death receptor of the TNFR superfamily. Fas-induced apoptosis is generally considered to be a noninflammatory process, contributing to the silent resolution of immune and inflammatory responses. However, accumulating evidence indicates that Fas may also induce cellular activation signals. We(More)
Acute lung injury (ALI) is characterized by an early inflammatory response followed by a late fibroproliferative phase, and by an increase in the bronchoalveolar lavage fluid (BALF) concentrations of bioactive soluble FasL (sFasL). Activation of Fas (CD95) has been associated with the development of lung fibrosis in mice. The goal of this study was to(More)
BACKGROUND Known risk factors for death following a diagnosis of tuberculosis may not be applicable to current U.S. cases. We evaluated the factors associated with all-cause mortality in patients with tuberculosis in Washington State. METHODS Using data from the Tuberculosis Information Management System of Washington State, we conducted a cohort study of(More)
BACKGROUND HIV-1 is frequently detected in the lungs of infected individuals and is likely important in the development of pulmonary opportunistic infections. The unique environment of the lung, rich in alveolar macrophages and with specialized local immune responses, may contribute to differential evolution or selection of HIV-1. METHODOLOGY AND FINDINGS(More)
Two new pathogens, Guignardia korthalsellae and Rosenscheldiella korthalsellae, are described from New Zealand's pygmy mistletoes (Korthalsella, Viscaceae). Both form ascomata on living phylloclades with minimal disruption of the tissue. Fungal hyphae within the phylloclade are primarily intercellular. Guignardia korthalsellae disrupts a limited number of(More)

It is an undecidable question whether a program schema terminates for a given interpretation. We show here that, in all (nontrivial) cases, if a program schema terminates it cannot be because of(More)
