Endoscopic sinus surgery (ESS) is today a common method for the treatment of chronic rhinosinusitis. Assessment of the results has been based mainly upon subjective evaluation, and only a few reports present objective measurements, In the present study, the 133-xenon washout technique was used for preoperative and postoperative evaluation of paranasal sinus ventilation in 12 patients selected for

What did make Europe's development different from that of other parts of the world?

Hematopoietic stem cells (HSCs) are defined by their unique properties to self-renew and differentiate into all hematopoietic cell lineages. Residing in the bone marrow (BM), adult HSCs are organized in a hierarchy of cells that differ in their self-renewal and proliferative capacity. Exact relationships of the various cells in the hematopoietic hierarchy, their potential to commit to certain line

Neutron deficient nuclei close to Sn-100 have been investigated in-beam using the NORDBALL detector array. A target of Fe-54 was bombarded with a beam of Ni-58 at 270 MeV. Evaporation residues were identified by detecting protons and alpha particles in a 4 pi charged particle multi-detector set-up and neutrons in a 1 pi neutron detector wall in coincidence with gamma rays. Excited states of the pr

The 2p(5)3s3p, 3p2, 3s4s, 3s3d, and 3s4f core-excited configurations of Mg II have been studied experimentally by beam-foil spectroscopy and theoretically by multiconfiguration Hartree-Fock calculations with Breit-Pauli relativistic corrections. The previously established energy levels belonging to the former four configurations have been reexamined leading to significant corrections of the 3p2 4D

I rapporten redovisas dagens kunskapsnivå avseende termiskt klimat, luftkvalitet, ljud samt elektromagnetiska fält. Dessutom redovisas de överkänslighetsrelaterade besvär, sjukdomsrelaterade besvär och symptom eller allmänna obehag av diskomfort som anses orsakas av inomhusmiljön. Rapporten är skriven så att de som arbetar med inomhusmiljörelaterade frågor, med varierande bakgrund, erbjuds en tvär

Radiative lifetimes of 30 excited states of Er 11, ranging in energy from 25 592 to 36 148 cm(-1), have been measured by means of a time-resolved laser-induced fluorescence (LIF) technique. Free, singly ionized erbium ions were produced in a laser-induced plasma. A tunable laser, with 1 ns duration pulse, was employed to selectively excite the Er+ ions. The lifetime values were evaluated from the

Head and neck squamous cell carcinomas (HNSCC) are often characterized by complex karyotypic changes, and a substantial proportion of the reported tumors have shown intratumor heterogeneity in the form of cytogenetically related (40%) or unrelated clones (20%). In order to study intratumor heterogeneity and to distinguish the temporal order of chromosome rearrangements in these tumors, two or more

OBJECTIVE: Glucagon-like peptide-1 (GLP-1) has been proposed as a new treatment modality for type 2 diabetes. To circumvent the drawback of the short half-life of GLP-1, inhibitors of the GLP-1-degrading enzyme dipeptidyl peptidase IV (DPP IV) have been examined. Such inhibitors improve glucose tolerance in insulin-resistant rats and mice. In this study, we examined the 4-week effect of 1-[[[2-[(5

In this review I will describe the advances that have recently been made in "traditional" two-dimensional gel based protein expression analysis. A major jump has been made toward the automation of gel image analysis and comparison, one of the major bottlenecks in the analysis chain as well as the automation of spot excision and preparation for mass spectrometric analysis. Currently the gel-based "

Analyses of mitochondrial cytochrome b diversity among avian blood parasites of the genera Haemoproteus and Plasmodium suggest that there might be as many lineages of parasites as there are species of birds. This is in sharp contrast to the approximately 175 parasite species described by traditional methods based on morphology using light microscopy. Until now it has not been clear to what extent

How is the conflict between a protection of accrued pension rights and economic, political and social interests in reforming the pension scheme resolved in different countries and regarding different kinds of pension schemes? What legal or political mechanisms exist to protect accrued pension rights and to resolve this conflict? This thesis takes a comprehensive view on the pension situation of t

A kinematic hardening plasticity model valid for finite strains is presented. The model is based on the well-known multiplicative split of the deformation gradient into an elastic and a plastic part. The basic ingredient in the formulation is the introduction of locally defined configurations center configurations- which are associated with deformation gradients that are used to characterize the k
