Asthma is characterized by bronchial mucosal inflammation. Although allergen-induced activation of cells binding allergen-specific immunoglobulin E (IgE) through high-affinity receptors (Fc(epsilon)RI) is believed to play some role in asthma, inappropriate synthesis of total or allergen-specific IgE cannot be demonstrated in some ("intrinsic") patients(More)
OBJECTIVE This imaging-based article systematically reviews traumatic knee dislocations. After completion, the reader should be familiar with the definition, epidemiology, cause, and classification schemes associated with these injuries, as well as the importance of timely diagnostic imaging and an accurate, detailed description of findings, particularly as(More)
Endoscopic third ventriculostomy (ETV) is considered by many authors the initial surgical procedure of choice for the treatment of non-communicant hydrocephalus. However, this procedure has early and late complications that neurosurgeons must be aware of when performing it. A retrospective study of infants and children treated with ETV at Children’s(More)
Eotaxin and other CC chemokines acting via CC chemokine receptor-3 (CCR3) are believed to play an integral role in the development of eosinophilic inflammation in asthma and allergic inflammatory diseases. However, little is known about the intracellular events following agonist binding to CCR3 and the relationship of these events to the functional response(More)
Introduction: Engineering constraints developed for the Mars Exploration Rovers (MER), their translation into ~185 potential landing sites and their down-selection to 6 high priority science sites have been described [1, 2]. These 6 sites (Meridiani-previously referred to as Hematite, Gusev, Isidis, Melas, Eos, and Athabasca) were evaluated in detail as to(More)
BACKGROUND Hereditary angioedema due to C1 inhibitor deficiency is characterized by recurrent acute attacks of swelling that can be painful and sometimes life-threatening. METHODS We conducted two randomized trials to evaluate nanofiltered C1 inhibitor concentrate in the management of hereditary angioedema. The first study compared nanofiltered C1(More)
Most cytokines possess multiple biologic activities. This study was undertaken to investigate the effect of rIL-1 beta, -2, -3, -4 and -6, IFN-gamma, TNF-alpha, and granulocyte-macrophage (GM)-CSF on basophils from 16 donors and the amount of histamine released was compared with that by partially purified mononuclear cell-derived histamine-releasing factor(More)
FcepsilonRI receptors play an important role in allergen-induced mediator release and antigen presentation by mast cells, basophils, and monocyte/macrophages in atopic disorders. The expression of FcepsilonRI by tissue eosinophils in atopic asthma after allergen challenge has not been established. For this reason we attempted to identify mRNA and protein(More)
Although usually the least prevalent blood leukocyte, the basophil can release potent soluble factors in response to multiple triggers. We purified basophils from normal volunteers by means of isopycnic centrifugation and affinity binding of mononuclear cells. The majority of the basophils from most subjects were recovered in a band formed between Percoll(More)
