Intrauterine sensitization of allergen-specific IgE analyzed by a highly sensitive new allergen microarray.

Background: To design a rational allergy prevention program, it is important to determine whether allergic sensitization starts in utero under the maternal immune system.

Objective: To investigate the origin of allergen-specific IgE antibodies in cord blood (CB) and maternofetal transfer of immunoglobulins.

Methods: The levels of food and inhalant allergen-specific IgE, IgA, IgG, and IgG(4) antibodies in CB and maternal blood (MB) from 92 paired neonates and mothers were measured by using a novel allergen microarray of diamond-like-carbon-coated chip, with high-sensitivity detection of allergen-specific antibodies and allergen profiles.

Allergen diagnosis microarray with high-density immobilization capacity using diamond-like carbon-coated chips for profiling allergen-specific IgE and other immunoglobulins.

The diagnosis of antibody-mediated allergic disorders is based on clinical findings, skin prick tests and detection of allergen-specific IgE in serum. Here, we present a new microarray technique of high-density antigen immobilization using carboxylated arms on the surface of a diamond-like carbon (DLC)-coated chip. High immobilization capacity of antigen on DLC chip at (0.

Platelet function and spontaneous thrombolytic activity of patients with cerebral infarction assessed by the global thrombosis test.

Measurements of platelet reactivity and assessment of the efficacy of antiplatelet drugs are widely recognized as pre-requisite for the diagnosis and treatment of stroke patients. A recently established shear-induced platelet reactivity test using non-anticoagulated blood (the Global Thrombosis Test) has facilitated measurements of physiologically relevant platelet function and thrombolytic activity. 195 healthy volunteers, not taking antiplatelet drugs or anticoagulants, and 185 patients with acute cerebrovascular diseases were enrolled.

Ionization of helium and argon by very slow antiproton impact.

The total cross sections for single ionization of helium and single and double ionization of argon by antiproton impact have been measured in the kinetic energy range from 3 to 25 keV using a new technique for the creation of intense slow antiproton beams. The new data provide benchmark results for the development of advanced descriptions of atomic collisions and we show that they can be used to judge, for the first time, the validity of the many recent theories.

A rare case of malignant glioma suspected to have arisen from a cavernous sinus.

A 55-year-old woman presented with a right trigeminal dysfunction (dysesthesia) initially, followed by right oculomotor and abducens paresis lasting 1 month. Neuroimaging studies showed an enhanced mass in the right cavernous sinus extending to the trigeminal ganglion. The extraparenchymal tumor located around the right trigeminal ganglion was totally removed, except for an intracavernous lesion, by the orbitozygomatic approach.
