The problem of enabling scientist users to submit jobs to grid computing environments will eventually limit the usability of grids. The eMinerals project has tackled this problem by developing the " my_condor_submit " (MCS) tool, which provides a simple scriptable interface to Globus, a flexible interaction with the Storage Resource Broker, metascheduling(More)
The ear, skin, and purified serosal mast cells of WBB6F1/J-(+/+) (WB-(+/+)) and WCB6F1/J-(+/+) (WC-(+/+)) mice contain high steady-state levels of the transcripts that encode mouse mast cell protease (mMCP) 2, mMCP-4, mMCP-5, mMCP-6, and mouse mast cell carboxypeptidase A (mMC-CPA). In contrast, no mast cell protease transcripts are present in abundance in(More)
A sthma is a complex disorder characterized by intermittent , reversible airway obstruction, and by airway hy-perresponsiveness and inflammation. Although its cause(s) remain unknown, we now recognize that asthma is a syndrome whose common pathologic expression is inflammation of the airways. The airways of patients with even mild asthma are inflamed, and(More)
A function of P in the alternative complement pathway is to prolong the first order decay of the hemolytic sites on EAC43B in a dose-dependent manner. As the number of initial convertase sites is not changed, even when activated properdin (P) increases the t1/2 10-fold or more, P acts to stabilize rather than to uncover additional sites. P binds to EAC43(More)
Normodense human peripheral blood eosinophils were isolated under sterile conditions from the 22/23 and 23/24% interfaces and the cell pellet of metrizamide gradients. After culture for 7 d in RPMI media in the presence of 50 pM biosynthetic (recombinant) human granulocyte/macrophage colony-stimulating factor (rH GM-CSF), 43 +/- 7% (mean +/- SEM, n = 8) of(More)
Whether or not a nontransformed, mature mouse mast cell (MC) or its committed progenitor can change its granule protease phenotype during inflammatory responses, has not been determined. To address this issue, the granule morphology and protease content of the MC in the jejunum of BALB/c mice exposed to Trichinella spiralis were assessed during the course(More)
Mast cells were enzymatically dissociated from human lung fragments that had been sensitized with serum from human allergic to ragweed and were enriched by isopyknic and velocity gradient sedimentation. Electron microscope examination showed that the mast cells were well preserved at the end of the dissociation and isolation and that the majority of their(More)
Human mast cells (hMCs) derived in vitro from cord blood mononuclear cells exhibit stem cell factor (SCF)-dependent comitogenic responses to T helper cell type 2 (Th2) cytokines. As cysteinyl leukotriene (cys-LT) biosynthesis is a characteristic of immunoglobulin (Ig)E-activated mucosal hMCs, we speculated that Th2 cytokines might regulate eicosanoid(More)
Maximum expiratory flow rate at 30 percent of vital capacity above residual volume served as an index of airway obstruction in comparing the effects of leukotriene C and histamine administered by aerosol to five normal persons. Leukotriene C was 600 to 9500 times more potent than histamine on a molar basis in producing an equivalent decrement in the(More)
Granulocytes with the hybrid characteristics of eosinophils and basophils have been identified in the bone marrow and peripheral blood of humans with myeloid leukemias. We now describe a technique by which such hybrid granulocytes can be developed in vitro from normal cord blood precursors cultured in the presence of recombinant human interleukin (rhIL) 3(More)
