Improvement of patient outcomes following therapeutic optimization of chronic urticaria: two-year data from France as part of the international real-life AWARE study.

Background: It is important to assess the burden of chronic urticaria (CU) with real-life studies. The AWARE study was performed in 36 countries over two years in CU patients resistant to H1-antihistamines.

Objectives: To correlate patient-reported outcomes and available therapeutic options in CU patients.

The burden of chronic spontaneous urticaria: unsatisfactory treatment and healthcare resource utilization in France (the ASSURE-CSU study).

Data on the clinical burden of chronic spontaneous urticaria (CSU) and economic consequences are lacking in France. To characterize the clinical and economic burden of CSU in symptomatic patients despite treatment by analysing data of French patients from the ASSURE-CSU study. ASSURE-CSU was an international observational study that included CSU patients with symptoms that lasted for 12 months or more despite treatment.

Observation of magnetic vortex pairs at room temperature in a planar α-FeO/Co heterostructure.

Vortices, occurring whenever a flow field 'whirls' around a one-dimensional core, are among the simplest topological structures, ubiquitous to many branches of physics. In the crystalline state, vortex formation is rare, since it is generally hampered by long-range interactions: in ferroic materials (ferromagnetic and ferroelectric), vortices are observed only when the effects of the dipole-dipole interaction are modified by confinement at the nanoscale, or when the parameter associated with the vorticity does not couple directly with strain . Here, we observe an unprecedented form of vortices in antiferromagnetic haematite (α-FeO) epitaxial films, in which the primary whirling parameter is the staggered magnetization.

Strain driven monoclinic distortion of ultrathin CoO films in the exchange-coupled CoO/FePt/Pt(0 0 1) system.

The structure and strain of ultrathin CoO films grown on a Pt(0 0 1) substrate and on a ferromagnetic FePt pseudomorphic layer on Pt(0 0 1) have been determined with in situ and real time surface x-ray diffraction. The films grow epitaxially on both surfaces with an in-plane hexagonal pattern that yields a pseudo-cubic CoO(1 1 1) surface. A refined x-ray diffraction analysis reveals a slight monoclinic distortion at RT induced by the anisotropic stress at the interface.

Bacterial lipopolysaccharide induces type 2 deiodinase in cultured rat astrocytes.

In the brain, 3,5,3'-triiodothyronine, which binds to the thyroid hormone receptor with high affinity, is locally generated from thyroxine by type 2 iodothyronine deiodinase (D2) expressed mainly in astrocytes and tanycytes. We have investigated the effects of bacterial lipopolysaccharide (LPS) on D2 in cultured rat astrocytes. LPS induced D2 activity with a lag-time of 4-8 h and a maximum at 24 h.
