The present studies examined the effects of oral treatment with cyclosporin A, betamethasone or azelastine administered over the time of sensitization with trimellitic anhydride on allergen-induced airway responses, compared to those of control animals given corn oil alone. Drugs were given for 8 days. The animals were sensitized with trimellitic anhydride (0.1 ml of 0.3% w/v) in corn oil given in

The lifetime of the b (1)Pi(u)(v=1) state in N-14(2) has been determined experimentally using a laser-based pump-probe scheme and an exceptionally long lifetime of 2.61 ns was found. Semiempirical close-coupling calculations of the radiative lifetime, which include Rydberg-valence interactions in the singlet manifold, are consistent with this large value, giving a value of 3.61 ns and suggesting a

All the support tools that developers are used to must be in place, if the use of model-centric development in companies hits to take off. Industry deals with big models and many people working on the same model. Collaboration in a team inevitably leads to parallel work creating different versions that eventually will have to be merged together. However, our experience is that at present the suppo

The atmospheric deposition of PCB within the catchment areas of an oligotrophic lake and an eutrophic lake in southern Sweden resulted in a flow of about 1 mg PCB.m(-2).year(-1) to the lakes. The sedimentation of the pollutants in the lakes (measured by sediment traps) was 110 and 52 mg PCB.m(-2).year(-1) for the oligotrophic and eutrophic lakes, respectively. The concentration of pollutants in pl

Abstract. Deliberate self-harm was studied in 14-year-old adolescents from four schools in southern Sweden with a test–retest design, using a nine-item version of the Deliberate Self-Harm Inventory. At Time 1, 40.2% of the adolescents indicated deliberate self-harm on at least one occasion compared with 36.5% at Time 2. Test–retest data showed high stability over periods of up to 2 months in durat

The luminescence polarization properties of GaInP islands have been investigated. The islands, which form during overgrowth of InP quantum dots, were studied using scanning tunneling luminescence (STL) and photoluminescence (PL). STL from these islands shows emission at an energy below the main emission peak of the bulk GaInP. The linear PL polarization anisotropy was measured at low temperature,

This article explores whether the impact of marital status on the risk of preterm birth varies in relation to marital practices in the population, defined by the proportion of out-of-marriage births. Data come from a case–control study of the determinants of preterm birth in 16 European countries (5456 cases and 8234 controls). There is a significantly elevated risk of preterm birth associated wit

Circling behaviour in unilateral 6-OHDA-lesioned rats is interpreted as being opposite in direction to the side of the brain with highest striatal dopaminergic activation. Ipsiversive rotation indicates an action on the intact striatum, while contraversive rotation demonstrates an effect on dopamine receptors in the denervated striatum and is taken as predictive of symptomatic benefit in Parkinson

We have investigated the dissolution of a natural oxide layer on a Nb(110) surface upon heating, combining x-ray reflectivity, grazing incidence diffuse scattering, and core-level spectroscopy. The natural oxide reduces after heating to 145 degrees C partially from Nb2O5 to NbO2, and an enrichment in subsurface interstitial oxygen by similar to 70% in a depth of 100 A is observed. After heating to

Both reduction in tidal volume (VT) and alveolar recruitment may be important to limit ventilator-associated lung injury during mechanical ventilation of patients with the acute respiratory distress syndrome (ARDS). The aim of this study was to assess the risk of alveolar derecruitment associated with VT reduction from 10 to 6 ml/kg. Whether this VT-related derecruitment could be reversed, either

By changing the three-dimensional structure, a protein can attain new functions, distinct from those of the native protein. Amyloid-forming proteins are one example, in which conformational change may lead to fibril formation and, in many cases, neurodegenerative disease. We have proposed that partial unfolding provides a mechanism to generate new and useful functional variants from a given polype

In this study, the signal cascade transducing carbachol stimulation into c-fos expression in SH-SY5Y neuroblastoma cells was investigated. 1,2-Diacylglycerol formation and c-fos expression were mediated via stimulation of muscarinic M1 receptors and the first 5 min of receptor stimulation were critical for these events. Application of 1,2-dioctanoylglycerol induced c-fos expression and this, as we

Solid state quantum computer hardware may be based on rare-earth-ion-doped crystals. The qubits can be encoded as nuclear spin states of an ensemble of, e.g., Pr3+ ions, randomly doped into a Y2SiO5 crystal. Two such qubits can control each other through the dipole blockade effect, and transfers between the two qubit states can be done at a high fidelity, despite the strongly inhomogeneous nature

Purpose To test the value of serum CA-125 measurements alone or as part of a multimodal strategy to distinguish between malignant and benign ovarian tumors before surgery based on a large prospective multicenter study (International Ovarian Tumor Analysis). Patients and Methods Patients with at least one persistent ovarian mass preoperatively underwent transvaginal ultrasonography using gray scale

We discuss the recent discovery by Oppenheimer et al. of old, cool white dwarf stars, which may be the first direct detection of Galactic halo dark matter. We argue here that the contribution of more mundane white dwarfs of the stellar halo and thick disc would contribute sufficiently to explain the new high velocity white dwarfs without invoking putative white dwarfs of the dark halo. This by no

The nonobese diabetic ( NOD) Nss1 and Idd5 loci have been associated with sialadenitis development in mice. In this study the NOD Nss1 and Idd5 loci were backcrossed onto the healthy control strain B10. Q by using the speed congenic breeding strategy, resulting in three congenic strains: B10. Q. Nss1, B10. Q. Nss1/Idd5 heterozygous and B10. Q. Nss1/Idd5 homozygous. We investigated the effects of t
