Continuous expression of E6- and E7-oncogenes of high-risk human papillomavirus (HPV) types is necessary for the development and maintenance of the dysplastic phenotype. The aim of the study was to determine the sensitivity and specificity of the APTIMA HPV mRNA assay (Hologic) in predicting future development of high-grade cervical intraepithelial neoplasia (CIN) among high-risk HPV-DNA-positive

The genus Caloplaca in the Nordic countries is currently under revision and this work has resulted in a number of new records for the Nordic countries or provinces within the countries. These records are presented here. Caloplaca arnoldii subsp. arnoldii is reported new to Sweden, C. conciliascens new to Norway and Sweden, C. castellana new to Finland, C. hungarica new to Norway and Sweden, C. isi

The conventional treatment for Dupuytren's disease is surgery. The introduction of alternative treatment strategies creates a need to track outcomes and costs relating to surgical treatment and risk factors, such as smoking and diabetes. This was the aim of the present study.

We present a compact and ultra-stable few-cycle OPCPA system. In two non-collinear parametric amplification stages pulse energies up to 17 mu J at 200 kHz repetition rate are obtained. Recompression of the broadband pulses down to 6.3 fs is performed with chirped mirrors leading to peak powers above 800 MW. The parametric amplification processes were studied in detail employing (2 + 1) dimensional

We use three-dimensional finite-difference time domain (3D-FDTD) simulations to investigate the field enhancement properties of tip-enhanced Raman scattering (TIERS) in order to find optimal geometric parameters of the metal tip and the metal substrate under certain excitation wavelengths with side illumination. The simulation results show that plasmon coupling effects between the metal tip and th

Background: The users of today's commercial prosthetic hands are not given any conscious sensory feedback. To overcome this deficiency in prosthetic hands we have recently proposed a sensory feedback system utilising a "tactile display" on the remaining amputation residual limb acting as man-machine interface. Our system uses the recorded pressure in a hand prosthesis and feeds back this pressure

A set of B(E2) values for the low-lying excited states in the radioactive isotope Sn-109 were deduced from a Coulomb excitation experiment. The 2.87-MeV/u radioactive beam was produced at the REX-ISOLDE facility at CERN and was incident on a secondary Ni-58 target. The B(E2) values were determined using the known 2(+) -> 0(+) reduced transition probability in Ni-58 as normalization with the semicl

Popular Abstract in Swedish Typ 2-diabetes mellitus ökar över hela världen med en trend av minskande debutålder. Sjukdomen är ett komplext natur som kan ses som en rad olika metabola sjukdomar med delvis lika symtom, men med helt olika bakgrundsorsaker. Gemensamt för alla varianter av diabetes är att blodsockret är förhöjt även vid fasta. Typ 2-diabetes kännetecknas av insulinresistens och en progType 2 diabetes mellitus is connected with elevated plasma glucose levels which negatively influence β-cells and cause impaired glucose-stimulated insulin secretion (GSIS). The aim of present thesis was to investigate the impact of long-term hyperglycemia on the pancreatic islet β-cell function. The data showed abnormally increased expression of inducible nitric oxide synthase (iNOS) protein in th

This paper explores the use of multi-agent continuous evacuation modelling for representing large-scale evacuation scenarios at music festivals. A 65,000 people capacity music festival area was simulated using the model Pathfinder. Three evacuation scenarios were developed in order to explore the capabilities of evacuation modelling during such incidents, namely (1) a preventive evacuation of a se

Many extensions of the Standard Model posit the existence of heavy particles with long lifetimes. In this Letter, results are presented of a search for events containing one or more such particles, which decay at a significant distance from their production point, using a final state containing charged hadrons and an associated muon. This analysis uses a data sample of proton-proton collisions at

We describe the characterization of the hydrodynamic properties of anisotropic magnetic nanoparticles using a combination of transmission electron microscopy (TEM) and dynamic as well as depolarized dynamic light scattering (DLS/DDLS). The particles used are nearly monodisperse hematite spindles with an average length of 280 nm and a minor axis of 57 nm, coated with a layer of silica of variable t

Recently, optimal linearly constrained minimum variance (LCMV) filtering methods have been applied to fundamental frequency estimation. Such estimators often yield preferable performance but suffer from being computationally cumbersome as the resulting cost functions are multimodal with narrow peaks and require matrix inversions for each point in the search grid. In this paper, we therefore consid

Emergency endovascular aneurysm repair (eEVAR) for ruptured abdominal aortic aneurysm (rAAA) must be carried out instantly. This requires firm logistics that include the ability to cross-clamp the aorta without delay. The present article focuses on the technique of balloon control of the aorta in eEVAR with aspects on indications as well as the organization of this type of vascular service. Transf

This paper looks at the notion of the body as an interior landscape that is made intelligible through visual representation. It discerns the key figure of the inner corporeal voyage, identifies its main elements and examines how contemporary artists working with performances and installations deal with it. A further aim with the paper is to discuss what kind of image of the body that is conveyed t

Many persons world wide are exposed to cold environments, either indoors for example in cold stores, or outdoors. Cold is a hazard to health and may affect safety and performance of work. Basis for the creation of safe and optimal working conditions may be obtained by the application of relevant international standards. ISO 11079(1)) presents a method for evaluation of whole body heat balance. On
