Background & Aims: The selective cyclooxygenase-2 inhibitor lumiracoxib has been shown to reduce endoscopically detected ulcers and ulcer complications in the upper gastrointestinal tract compared with nonselective nonsteroidal anti-inflammatory drugs. We investigated whether lumiracoxib would reduce small-bowel injury compared with naproxen plus omeprazole. Methods: Healthy volunteers were ra
A list of lichens collected on two field trips to Estonia by botanists from the universities of Stockholm and Lund in 1989 is presented. 74 species are reported for the first time from Estonia. Several other species have previously been reported only a few times. From the 11th to the 20th of June 1989 nine botanists from Stockholm visited Estonia and Latvia, and four lichenologists from Lund visit
Objective: The aim of this study was to analyze the impact of reproductive factors on breast cancer risk among Swedish women by using nationwide population registers. Methods: A cohort including all Swedish women born between 1920 and 1959 was followed up to 1997 by record linkage to different population-based registers. More than 4 million children were linked to the women in the cohort and 60,32
This paper presents a voltage-source-converter (VSC)-FfVDC-supplied industrial system with onsite generation where the VSC-HVDC and generator are taking part in the voltage and frequency control. The reason for using a frequency controller in the converter is to increase the ridethrough capability of the VSC-HVDC-supplied industrial system by exploiting the inertia energy of rotating masses in cas
Background: To examine whether neighbourhood non-employment is associated with daily smoking after adjustment for individual characteristics, such as employment status. Methods: Cross-sectional study of a simple, random sample of 31,164 women and men aged 25-64, representative of the entire population in Sweden. Data were collected from the years 1993-2000. The individual variables included age, s
Partially depolymerized, water-soluble hemicelluloses were solubilized from flax shive employing hydrothermal microwave treatment and thereafter subjected to ion-exchange chromatography, enzymatic purification and/or size-exclusion chromatography (SEC). The oligo- and polysaccharide fractions thus obtained were characterized with respect to molar mass, molar mass distribution, degree of polymeriza
Acrylamide exposure was investigated in subgroups of the EPIC study population (510 subjects from 9 European countries, randomly selected and stratified by age, gender, and smoking status) using hemoglobin adducts of acrylamide (HbAA) and its primary metabolite glycidamide (HbGA). Blood samples were analyzed for HbAA and HbGA by HPLC/MS/MS. Statistical models for HbAA and HbGA were developed inclu
BACKGROUND & AIMS: Hereditary hemochromatosis (HH) is an autosomal-recessive disorder characterized by iron overload. Relatives of HH patients were screened and those with HH-associated mutations and an increased iron load were identified. However, little is known about their mortality or strategies for their management. We assessed mortality among Swedish patients with HH and their first-degr
Functionally distinct subsets within the T-helper (CD4+) cell population have been described in man, rat and mouse. We have shown previously that the CD4+ 45R- human lymphocytes are producers of IL-2 within 24 hr of polyclonal stimulation and are the major interferon (IFN) producers. The mAbs 4B4 (CDw29) and Leu 8 (p80) are here used together with Leu-18 (CD45R) to characterize the subpopulations
Purpose. Patients with fibromyalgia (FM) and chronic widespread pain (CWP) find physical activity troublesome. The purpose was to develop a questionnaire to investigate the experience of physical activity in FM and CWP populations. Method. A questionnaire was developed from a qualitative study. After that, a total of 204 patients with FM or CWP completed the questionnaire. A factor analysis was co
The effect of vaginal washing with chlorhexidine acetate, 2 g/l at delivery, on the colonization of the urogenital tract with group B streptococci (GBS) 4 days later was investigated. Patients who were culture-positive for GBS in urethra and/or cervix in pregnancy weeks 32 and 36 as well as at delivery were included in a prospective study. The washing procedure was performed in 31 parturients, and
We analyse recent experiments on momentum shearing interferometry of electron wave packets1,2 by using an optical analogy with shearing interferometry for optical waves. This analogy offers a convenient point of view to discuss the capabilities and difficulties of this technique used to access the phase of electron wave packets.
Recent developments in European energy policy reveal an increasing interest in implementing the so-called ‘Tradable White Certificate’ (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and co
The entrepreneur is the central actor in generating entrepreneurial activity. Thus, it is important to understand the motivational characteristics and variables associated with entrepreneurial behavior spurring people to become entrepreneurs. For this study, a comparative analysis of high-tech entrepreneurs in Switzerland and the UK was undertaken to determine the extent to which they differ in te
Increased QT dispersion and loss of sinus rhythm were both associated with sudden cardiac death in patients with transposition of the great arteries after Mustard and Senning operations at the early and late postoperative periods. A combination of increased QT dispersion with loss of sinus rhythm increases the positive predictive value for sudden cardiac death in patients with transposition of the
We present a method for parametrizing the Zeeman effect in hydrogen-like systems in high-temperature plasmas, where the fine-structure is completely unresolved. The method is based on the observation that the different polarization components behave collectively like separate entities, with simple relations. The entire Zeeman pattern can then be reduced to just three components, whose dependence o
In the rat, gastric histamine is stored mainly in the enterochromaffinlike cells. Gastrin releases histamine from these cells, and long-term hypergastrinemia results in hyperplasia. The effect of sustained hypergastrinemia on histamine-depleted enterochromaffinlike cells was studied by measuring histidine decarboxylase activity and histamine concentrations and by using quantitative histology.
