The activation of endothelium is important in recruiting neutrophils to sites of inflammation and in modulating their function. We demonstrate that conditioned medium from cultured, activated endothelial cells acts to significantly delay the constitutive apoptosis of neutrophils, resulting in their enhanced survival and increased phagocytic function.

PURPOSE The aims were to assess the safety, pharmacokinetics, maximum tolerated dose, and antitumor activity of AMG 102, a fully human hepatocyte growth factor/scatter factor (HGF/SF)-neutralizing monoclonal antibody, in patients with solid tumors. EXPERIMENTAL DESIGN Patients (N = 40) with refractory advanced solid tumors were enrolled into six(More)

BACKGROUND AND PURPOSE Macrophage-1 antigen (Mac-1) (CD11b/CD18), a leukocyte beta2 integrin, facilitates neutrophil adhesion, transendothelial migration, phagocytosis, and respiratory burst, all of which may mediate reperfusion-induced injury to ischemic brain tissue in conditions such as stroke. To determine the role of Mac-1 during ischemia and(More)
The therapeutic efficacy and side-effects of two preparations of levodopa with extracerebral decarboxylase inhibitors have been compared in 19 patients with idiopathic parkinsonism in a blind randomised crossover trial. The mean daily dose of levodopa was 658 +/- 64 mg/day (mean +/- S.E.M.) when given together with carbidopa 66 mg/day and 605 +/- 59 mg/day(More)
Recepteur d'origine nantais (RON) is a receptor tyrosine kinase closely related to c-Met. Both receptors are involved in cell proliferation, migration, and invasion, and there is evidence that both are deregulated in cancer. Receptor over-expression has been most frequently described, but other mechanisms can lead to the oncogenic activation of RON and(More)
Sphingosine kinases (SPHKs) are enzymes that phosphorylate the lipid sphingosine, leading to the formation of sphingosine-1-phosphate (S1P). In addition to the well established role of extracellular S1P as a mitogen and potent chemoattractant, SPHK activity has been postulated to be an important intracellular regulator of apoptosis. According to the(More)
Non–small-cell lung cancer (NSCLC) is categorized into various histologic subtypes that play an important role in prognosis and treatment outcome. We investigated the antitumor activity of motesanib, a selective antagonist of vascular endothelial growth factor receptors (VEGFR) 1, 2, and 3, platelet-derived growth factor receptor, and Kit, alone and(More)
Seventeen polymorphic microsatellite DNA markers were isolated from the loggerhead shrike (Lanius ludovicianus) using individuals from two geographically distinct populations (Ontario and mainland California). The number of alleles per locus ranged from 6 to 20 and expected heterozygosity varied from 0.639 to 0.902. All loci were heterozygous and private(More)
