An improved ELISA method for the detection of Staphylococcal. Enterotoxin B (SEB) in protein A preparations is presented. Fab fragments were obtained by digestion with papain of anti-SEB IgG bound to SEB immobilized on Sepharose 4B. Anti-SEB and peroxidase-labeled Fab fragments from secondary antibodies were successfully used in a modified ELISA of SEB in protein A preparations. SEB-Sepharose was

Aim: To investigate the anatomical and functional results and the complications in eyes operated on using vitrectomy without scleral buckling for all forms of rhegmatogenous retinal detachment ( RRD). Methods: All cases of primary RRD at the University Hospital of Lund, Lund, Sweden, treated by one surgeon during a period of 3 years were retrospectively reviewed. In 131 ( 98%) of 134 consecutive c

Leukotriene antagonists are effective in the treatment of exercise-induced bronchoconstriction. Montelukast is a specific cysteinyl-leukotriene receptor1 antagonist without known effects on the pulmonary vessels, which in theory should be advantageous with respect to gas exchange. In addition to lung function, we investigated the effects of montelukast on parameters of gas exchange and physical pe

Objectives To explore case ascertainment, hospitalization, characteristics of both hospitalized and non-hospitalized patients in a population-based group of stroke patients. Materials and methods One-year screening in Lund-Orup district for first-ever strokes using multiple prospective and retrospective methods. Results A total of 456 patients with first-ever stroke (n = 412 prospective screening

A nonlinear 3D finite element model and a theoretical parameter study in relation to glued-in rods for timber structures are presented. A strain-softening crack band model was used to characterise the behaviour of the adhesive layer between the rod and the wood. The model is general in the sense that it bridges the gap between the theory of an ideal plastic bondline and the theory of linear elasti

Intensive harvesting of forest residues for energy production may lead to the depletion of organic matter and mineral nutrients in the forest floor. In order to restore nutrient content wood ash has been suggested as a fertiliser. Ectomycorrhizal (EM) fungi arc involved in the nutrient uptake of forest trees and this study investigates the influence of intensive harvesting and wood ash fertilisati

The formerly grazed forest (utmark) was the dominant land use on most farms in southern Sweden until about 100 years ago. Here I describe the changed structure and tree species composition over time of the utmark on three farms owned by the church in the central part of Stenbrohult. In this area Carl Linnaeus spent his first 20 summers until 1728. The study is based on old forest management plans,

Popular Abstract in Swedish Förekomsten av hjärt-kärlsjukdomar skiljer sig mycket mellan olika jordbruksbaserade samhällen, medan de praktiskt taget saknas helt bland samhällen som inte är baserade på jordbruk, såsom jägar- och samlarsamhällen. När man letar efter livsstilsfaktorer som skulle kunna gynna uppkomsten av kardiovaskulära sjukdomar verkar det därför logiskt att fokusera på livsstilen iThe prevalence of cardiovascular diseases (CVD) exhibits considerable variation across agrarian societies, whereas they are virtually absent in non-agrarian societies such as hunter-gatherer and horticultural societies. When looking for lifestyle factors which could promote CVD, it therefore seems logical to focus on the agrarian lifestyle and ways in which it departs from a non-agrarian lifestyle

The aim of the present study is to examine the validity of using silicon semiconductor detectors in degraded electron beams with a broad energy spectrum and a wide angular distribution. A comparison is made with diamond detector measurements, which is the dosimeter considered to give the best results provided that dose rate effects are corrected for. Two-dimensional relative absorbed dose distribu

This paper presents an innovative research on urban risk reduction and climate change adaptation that combines case studies, grounded theory and systems analysis, which could be used as a template for similar intersectoral and interdisciplinary investigations. Such a ‘case studies–grounded theory–systems analysis approach’ permits a grounded theory to be built from case study data, which is viewed

Given an electronic wave function, generated by the MCHF program (LS format) or the MCHF_CI program (LSJ format), this program computes the hyperfine interaction constants, A(J) and B(J). In strong experimental magnetic fields, the splitting is also affected by the off-diagonal hyperfine constants A(J,J-1), B(J,J-1), and B(J,J-2) and these are computed as well, depending on the input data.

The ambiguity domain plays a central role in estimating the time-varying spectrum of a non-stationary random process in continuous time, since multiplication in this domain is equivalent with estimating the covariance function of the random process using an intuitively appealing estimator. For processes in discrete time there exists a corresponding covariance function estimator. The ambiguity doma

Objective. Serum calcium concentrations have been associated with the risk of malignant disease, especially breast cancer. Thus, determinants of serum calcium concentrations, with special regard to risk factors of breast cancer, are of great interest. Material and methods. Previous studies have either been small or they have not focused on reproductive factors. The present study examined serum cal

In this study, we analysed the ease of use of three computer programs for self-registration of job seekers. The programs were developed in somewhat different activity contexts. The differences found between the programs in two experiments appeared to result from a combination of fewer constraints on individual input demanded by Job Seeker Bank and Af Explore and from the programs’ better adaptatio

Weak convergence of the multivariate point process of upcrossings of several high levels by a stationary Gaussian process is established. The limit is a certain multivariate Poisson process. This result is then used to determine the joint asymptotic distribution of heights and locations of the highest local maxima over an increasing interval. The results are generalized to upcrossings and local ma

Echocardiography has a vital role for diagnosing and monitoring infectious endocarditis. The recently published Swedish guidelines for diagnosis and treatment of infectious endocarditis recommend overuse of transoesophageal echocardiography, which is not supported by the literature. The European Society of Cardiology presents a considerably more appropriate opinion.
