Recently, there have been significant advances in several areas of language technology, including clustering, text categorization, and summarization. However, efforts to combine technology from these areas in a practical system for information access have been limited. In this paper, we present Columbia's Newsblaster system for online news summarization.(More)
Neutrophil migration into the airspaces of the lung is thought to contribute to the alveolar damage and subsequent fibrosis in idiopathic pulmonary fibrosis (IPF). Interleukin 8 (IL-8), a monocyte- and macrophage-derived cytokine, displays potent chemotactic and activating properties towards neutrophils and thus may contribute to the pathogenesis of IPF.(More)
The rapid expansion of multimedia digital collections brings to the fore the need for classifying not only text documents but their embedded non-textual parts as well. We propose a model for basing classification of multimedia on broad, non-topical features, and show how information on targeted nearby pieces of text can be used to effectively classify(More)
Annotating photographs automatically with content descriptions facilitates organization, storage, and search o ver visual information. We present a n i n tegrated approach for scene classiication that combines image-based and text-based approaches. On the text side, we use the text accompanying an image in a n o vel TF*IDF vector-based approach to(More)
The objective of this study was to investigate the mechanisms that contribute to the generation of macrophage functional diversity. Exposure of mouse bone marrow-derived macrophages to beta-1,3-glucan, a particulate inflammatory stimulus, or polyinosinate-polycytidylate (poly[I:C]), a stimulus of macrophage cytocidal activation, induced distinct and(More)

Annexin IV was cloned and sequenced from a mouse bone marrow-derived macrophage cDNA library, and was found to exist as three different alternatively spliced transcripts. One transcript contained an additional 688 base pairs inserted within the coding region of the gene including an in-frame stop codon. Translation of this transcript in vitro confirmed the(More)
Small GTP-binding proteins of the Rho family are implicated in the regulation of phospholipase D (PLD). However, few studies have addressed their role in agonist-stimulated PLD activity in vivo. Stable lines of Rat1 fibroblasts overexpressing RhoA were shown to have altered morphology. Moreover, they demonstrated increased PLD activity when stimulated with(More)
