OBJECTIVE: To study the effect of postoperative thyroxine on the volume of the thyroid remnant after lobectomy for benign nontoxic goitre. DESIGN: Prospective, randomised study. SETTING: University hospital, Sweden. SUBJECTS: 50 consecutive patients who underwent lobectomy for benign non-toxic goitre. INTERVENTIONS: Patients were randomised postoperatively to take thyroxine 0.1 mg or placebo daily
In this paper we present an investigation of the dielectric response of H2O(1) and D2O(1) as a function of temperature from a supercooled state to near the boiling point. The data are obtained using THz-time domain spectroscopy, and covers the frequency range from 0 1-2 THz corresponding to 3 to 66 cm(-1). Before presenting the experimental results, we give a short introduction to some of the prop
BACKGROUND: Development of proximal and distal colorectal cancers involve partly different mechanisms associated with the microsatellite instability (MSI) and the chromosomal instability (CIN) pathways. Colorectal cancers in patients under 50 years of age represent about 5% of the total number of tumors and have been associated with an increased frequency of MSI tumors. However, MSI and CIN may pl
The impacts of climate change are likely to exacerbate many problems that coastal areas already face. In this study, we used multinomial logistic regression to examine human perception of climate change based on a cross-sectional survey of 1253 individuals in coastal regions of Tanzania. This was complemented with time series analysis of 50-year meteorological data. The results indicate that self-
Objective. While the prevalence of radiographic thumb carpometacarpal (CMC1) osteoarthritis (OA) is well-described, little is known about clinically symptomatic disease presenting to physicians for care. We sought to determine the prevalence of doctor-diagnosed CMC1 OA. Methods. Using health care data from Skane in southern Sweden (population 1.24 million), we identified all adults ages >= 20 year
Estrogen exerts vasculoprotective effects in different experimental settings through inhibition of vascular smooth muscle cell proliferation, stimulation of nitric oxide production and attenuation of inflammation. Although these estrogen-evoked beneficial effects have been attributed to estrogen receptor α (ERα), also ERβ and the novel ER GPR30/GPER1 probably play significant roles in vascular est
Background: Evidence from twin and molecular genetic studies is accumulating that Autism Spectrum Disorder (ASD) shares substantial etiological factors with other disorders. This is mirrored in clinical practice where ASD without coexisting disorders is rare. The present study aims to examine the range of coexisting disorders in ASD in a genetically informative cohort. Methods: Parents of all Swed
In recombinant, xylose-fermenting Saccharomyces cerevisiae, about 30% of the consumed xylose is converted to xylitol. Xylitol production results from a cofactor imbalance, since xylose reductase uses both NADPH and NADH, while xylitol dehydrogenase uses only NAD(+). In this study we increased the ethanol yield and decreased the xylitol yield by lowering the flux through the NADPH-producing pentose
A numerical study of how changes in the micromechanical modeling affect the formability of voided metal sheets is conducted. A homogenization technique, where periodic representative volume elements are used, permits investigations of the global formability where the local material mechanisms and the microstructure are accounted for. A nonlocal material model, containing a constitutive material le
One problem with web servers is that they are sensitive to overload. The servers may become overloaded during temporary traffic peaks when more requests arrive than the server is designed for. Because overload usually occurs rather seldom, it is not economical to overprovision the servers for these traffic peaks, instead admission control mechanisms can be implemented in the servers. This pa per i
Objective. The aim of the study was to survey existing research about fatigue among older people with chronic non-malignant pain. Method. A structured literature review was carried out using the Medline database. The terms ‘fatigue’ and ‘tiredness’ were used synonymously. These subject headings were combined with pain. A literature search was made in 2004 and included articles back to 1995. Resu
Most of the common modeling approaches to premixed combustion in engineering applications are either based on the assumption of infinitely fast chemistry or the flamelet assumption with simple chemistry. The level-set flamelet library approach (FLA) has shown great potential in predicting major species and heat release, as well as intermediate and minor species, where more simple models often fail
Introduction: Complement activation is involved in rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and atypical hemolytic uremic syndrome (aHUS). Autoantibodies to complement inhibitor factor H (FH), particularly in association with deletions of the gene coding for FH-related protein 1 (CFHR1), are associated with aHUS. Methods: Autoantibodies against FH, factor I (FI) and C4b-bindin
Air traffic control activities demand a high level of safety performance. Methods for identifying and monitoring work and situational factors to enable safety performance improvements are rare. This paper reports on the development of such a questionnaire-based tool for the Swedish air navigation services provider. Results from interviews specified eight aspects to be assessed by the questionnaire
Since publication of the 1998 UNEP Assessment, there has been continued rapid expansion of the literature on UV-B radiation. Many measurements have demonstrated the inverse relationship between column ozone amount and UV radiation, and in a few cases long-term increases due to ozone decreases have been identified. The quantity, quality and availability of ground-based UV measurements relevant to a
The addition of serotonin to preparations of 32P-labelled human platelets resulted in a time- and dose-dependent hydrolysis of [32P]phosphatidylinositol 4,5-bisphosphate (PIP2) and formation of [32P]phosphatidic acid (PA). This response was inhibited by the serotonin2 receptor antagonist ritanserin, indicating that the stimulation was mediated via the serotonin2 receptor. The addition of 50-150 mM
Mirtazapine pharmacokinctic (PK) data from patients on long-term treatment for major depression have never been investigated. For this reason, in a large naturalistic outpatient study (prospective, multicenter, open-labeled, and noncomparative) conducted in Sweden in the period 2000 2002, one of the main objectives was to outline the inter- as well as intraindividual PK variance of mirtazapine and
We investigate the performance of overload control through queue length for two different web server architectures. Both of them use finite queue lengths to prevent servers from being overloaded. One architecture prioritizes requests from established sessions while the other treats all requests equally. First, we introduce queueing models for these two systems. Then, we define and explain a new we
