Företag, regioner och internationell konkurrens : Om regionala resursers betydelse

The overall purpose of this thesis is to study regional variation in the international competitiveness (export capacity, market orientation and production aboard) of Swedish manufacturing industry, and to contribute to explaination of this variation. The explanation is sought for in differences in regional production milieu as well as in differences in localization of industrial sectors and claims

Pitfalls in the interpretation of long-term inhalation experiments

Age- and weight-matched groups of mice were enclosed in airtight chambers and exposed to clean, filtered air for 1 month. At the end of the exposure period, body, liver and spleen weights and plasma butyrylcholinesterase (BuChE) activity were measured. More than twice as many significant differences in these parameters occurred compared with the expected results if only random differences existed

Pristane, a non-antigenic adjuvant, induces MHC class II-restricted, arthritogenic T cells in the rat.

Pristane-induced arthritis (PIA) in rats, a model for rheumatoid arthritis (RA), is a T cell-dependent disease. However, pristane itself is a lipid and unable to form a stable complex with a MHC class II molecule. Therefore, the specificity and function of the T cells in PIA are as unclear as in rheumatoid arthritis. In this study, we show that activated CD4+ alphabetaT cells, which target periphe

Pre-eclampsia is a potent risk factor for deterioration of retinopathy during pregnancy in Type 1 diabetic patients

The aim of the present study was to examine the influence of pregnancy on deterioration of retinopathy in patients with Type 1 diabetes mellitus. Sixty-five pregnant Type 1 diabetic women attending the University Hospital in Lund were studied retrospectively. The degree of retinopathy, and levels of HbA1c and blood pressure 12 months before, during, and 6 months after pregnancy were compared of th

Fetal ductus venosus, middle cerebral artery and umbilical artery flow responses to uterine contractions in growth-restricted human pregnancies.

Objective To explore fetal ductus venosus (DV) flow velocity changes relative to umbilical artery (UA) blood flow and brain-sparing flow (BSF) during uterine contractions. Methods Forty-five term fetuses suspected of having growth restriction were exposed to an oxytocin challenge test (OCT) with simultaneous Doppler velocimetry in the UA, middle cerebral artery (MCA) and DV. Basal BSF was defined

Long term efficacy and safety of cyclosporin versus parenteral old in early rheumatoid arthritis: a three year study of radiographic progression, renal function, and arterial hypertension

Objective: To compare the three year safety and efficacy of cyclosporin and parenteral gold in the treatment of early, active, severe rheumatoid arthritis (RA), and to study the reversibility of cyclosporin associated renal dysfunction in patients who discontinued cyclosporin treatment. Methods: The patients continued to receive cyclosporin or parenteral gold in an 18 month open extension to an 18

U-EPX levels and wheezing in infants and young children with and without RSV bronchiolitis

An association between severe infant bronchiolitis due to respiratory syncytial virus (RSV) and subsequent wheezing is well documented. High levels of urinary eosinophil protein X (U-EPX) have been related to active disease in asthmatic children. The aim of this study was to analyse whether RSV bronchiolitis leads to an increase in U-EPX levels and whether wheezing is more common in children with

An evolutionary analysis of the aetiology and pathogenesis of juvenile-onset myopia

The available evidence suggests that both genes and environment play a crucial role in the development of juvenile-onset myopia. When the human visual system is examined from an evolutionary perspective, it becomes apparent that humans, living in the original environmental niche for which our species is genetically adapted (as hunter-gatherers), are either slightly hypermetropic or emmetropic and

Styr- och reglertekniska funktioners inverkan på energiförbrukningen

Rapporten behandlar styr- och reglertekniska funktioners inverkan på energiförbrukningen i byggnader. Den omfattar presentation av undersökta objekt med beskrivning av de olika installationssystemen, redogörelse för redan gjorda driftserfarenheter samt beskrivning av energibesparande modifieringar av driftsätt.

The eta(c)(2980) formation in two-photon collisions at LEP energies

eta(c)(2980) production in gammagamma interactions has been detected via its decays into K(s)(0)K(-/+)pi(-/+), K+K-K+K- and K(+)K(-)pi(+)pi(-) in the data taken with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative width averaged over all observed decay channels is Gammagammagamma=13.9+/-2.0(stat.)+/-1.4(syst.)+/-2.7 (BR) keV. No direct decay channel eta(c)-->pi(+)pi(-)pi(+)

Isoform distribution and tissue contents of contractile and cytoskeletal proteins in hypertrophied smooth muscle from rat portal vein

Growth of the smooth muscle in the rat portal vein was initiated by an increased transmural pressure. After 7 days, the cross-sectional area of the vessel wall and the maximal active force of the longitudinal muscle layer had increased twofold. Electron microscopy showed that the cell cross-sectional area was increased, suggesting cellular hypertrophy. Increased amounts of intermediate (10 nm) fil

Delayed Onset of Ototoxic Effects of Gentamicin in Patients with Meniére's Disease

In treatment of Meniére's disease, installations of gentamicin are continued until there are signs of disturbance of vestibular or cochlear function. However, since it has been demonstrated that gentamicin is eliminated slowly from the inner ear, a continuing ototoxic effect may be suspected. The present study aimed to investigate the delay of onset of symptoms of ototoxic effects. Five patients w

Latent Autoimmune Diabetes in Adults: Definition, Prevalence, {beta}-Cell Function, and Treatment.

Latent autoimmune diabetes in adults (LADA) is a disorder in which, despite the presence of islet antibodies at diagnosis of diabetes, the progression of autoimmune ß-cell failure is slow. LADA patients are therefore not insulin requiring, at least during the first 6 months after diagnosis of diabetes. Among patients with phenotypic type 2 diabetes, LADA occurs in 10% of individuals older than 35

Changes of bone mineral mass and soft tissue composition after hip fracture

The aim of this prospective longitudinal study was to measure prospectively the bone mineral density (BMD) and anthropometric variables after a hip fracture. In particular, we studied changes in the BMD in both the injured and uninjured hips, and examined if the postoperative mortality rate and complications, including pseudarthrosis of the fracture and late segmental collapse of the head of the f
