Aims: The airways of patients with asthma are characterized by chronic inflammatory changes comprising mainly T-cells and eosinophils, and airway remodelling with goblet cell metaplasia and submucosal gland hyperplasia. Mucus hypersecretion is often a marked feature, particularly in status asthmaticus. The matrix of airway sputum consists of high molecular glycoproteins and mucins. In this study,
As the amount of high dimensional data becomes increasingly accessible and common, the need for reliable methods to combat problems such as overfitting and multicollinearity increases. Models need to be able to manage large data sets where predictor variables often outnumber the amount of observations. In this study the frequentist and Bayesian framework is tested against each other based on three
One of the most common types of bridges in Sweden is the integral bridge. What characterizes the integral bridge is the lack of bearings and expansion joints. The advantage of this construction is that the horizontal forces can be distributed throughout the structure. A problem is the restraint forces that occur due to, for instance, changes in temperature. Integral bridges are now often designed
Purpose: Healthy spinal balance is dependent on spinal sagittal alignment. It is evaluated by several spinopelvic measures. The objective of this study is to investigate the effect of age and body mass index and the bone mineral density on the several vertebral measures and sagittal spinopelvic measurements. Methods: In this cross-sectional study, a total of 89 female patients were grouped accordi
High-resolution, non-invasive, 3D-imaging techniques would greatly benefit the investigation of the localization properties of tumor-specific radiopharmaceuticals in laboratory animals. The present study reports how pinhole SPECT can be applied to tumor localization studies in small laboratory animals to provide high resolution SPECT images in vivo. Pinhole SPECT was performed using a rotating sci
We have investigated the spin polarization of electrons and holes in InAs/GaSb broken-gap quantum wells under nonequilibrium conditions when a dc electric field is applied parallel to interfaces. The existence of a nonzero asymmetric part of the quasiparticle distribution function caused by the dc current and the spin-split of the electron-hole hybridized states generates a finite spin polarizatio
BACKGROUND: Hepatitis C virus (HCV) is a known blood-borne hepatotropic virus for which antibody screening of blood donors is universally practiced. The newly identified GB virus C (GBV-C) and its strain variant hepatitis G virus (HGV) are of unknown pathogenic significance, and screening of blood donors for this agent has not yet been implemented. Polymerase chain reaction (PCR) is the most sensi
Like most L2 speakers, speakers of early L1, children with SLI, and Broca’s aphasics lack the or¬dinary speaker’s ability to produce utterances on line with almost no errors. Often they produce well-formed utterances, but quite frequently they produce errors that are almost non-existent in the speech of normal grown-up speakers. In my paper I will suggest, based on empirical material from Swedish,
Popular Abstract in Swedish En ny bildgivande detektor för realtids registreringar av laddade partiklar (beta-partiklar, konversions-elektroner och alfa-partiklar) från tunna preparat har utvecklats, Betakamera. Den består av en ljuskänslig detektor, baserad på mikrokanalplattor, en fotokatod och en resistiv anod . Preparatet som ska registreras placeras mot en plastscintillator, vilken är monteraA new detector for on-line digital detection of charged particles (beta-particles, conversion electrons and alpha-particles) from thin samples for rapid autoradiography has been developed; the Beta Camera. The device consists of a photon-sensitive detector (image photon detector, IPD); the main component of which is a microchannel plate. The sample to be measured is mounted in close contact to a t
Collagen VII is an essential anchoring protein in the basement membrane zone, maintaining the attachment of stratified and pseudostratified epithelia to the underlying interstitial matrix. However, collagen VII is largely unexplored in normal lungs and idiopathic pulmonary fibrosis (IPF), a disease characterized by excessive accumulation of extracellular matrix (ECM) and aberrant re-epithelializat

There was an increase in students wh
Oscillation frequency and damping of electro-mechanical modes in a power system have traditionally been determined from events caused by large disturbances such as line switchings or generator tripping. Recent papers have shown the possibility to extract this information during normal operation from measurements of power through, or angle difference across, a transmission line. In this paper these
Popular Abstract in Swedish I avhandlingen studeras plasminogenaktiverings-systemets (PA-systemets) komponenter i livmoderslemhinnan. PA-systemet reglerar omvandlingen av plasminogen till plasmin. Plasminogen är ett inaktivt enzym som finns överallt i kroppsvätskor samt i kroppens olika organ. Aktiveringen katalyseras av aktivatorer, antingen urokinase plasminogen activator (uPA) eller tissue plasThe release of urokinase plasminogen activator (uPA) from endometrial stromal cells decreased after progesterone stimulation, due to upregulation of PA inhibitor 1 (PAI-1) and uPA receptor (uPAR). Subsequently, the uPA:PAI-1 complex was internalized and degraded via uPAR. Predecidual cells in the late secretory phase expressed PAI-1 and uPAR, supporting a specific role for predecidual cells in the
Companies always strives to acheive as eective inventory control as possible. At the same time, a suciently high delivery accuracy to satisfy the customer is pursued. One prerequisite for successfully accomplishing this is to anticipate customer demand in advance. An approximation of the demand in advance is called forecasting. Forecasting implies that dierent techniques are used to predict future
Vegetation fire is one of the naturally occurring disturbances within the Earth system, changing vegetation dynamics and modulating carbon storage in the terrestrial biosphere. While fires are essential to many ecosystems, fire dynamics have been increasingly shaped by human actions since the late eighteenth century. The main drivers behind those changes are climate change and direct human activit
Hirschsprung’s disease is a rare, congenital disease characterized by a lack of nerves in parts of the gastrointestinal tract. The disease is often diagnosed early in a child’s life, as the lack of nerves inhibits the passing of stool. Surgery is required to remove the affected part of the intestine. Today intra-operative biopsies are taken to determine where the diseased part of the intestine end
One of the most cited studies within the field of binary choice models is that of Klein and Spady (1993), in which the authors propose a semiparametric estimator for use when the distribution of the error term is unknown. However, although theoretically appealing, the estimator has been found to be difficult to implement, and therefore not very attractive from an applied point of view. The current
