Field trials in three European countries, the Netherlands, Spain and Sweden were carried out in order to investigate the effects of an in-car speed limiter. The trials were carried out on urban and rural roads including motorways. A so-called unobtrusive instrumented car was used, where all the measuring equipment was hidden. All the speed limit categories in the respective countries, ranging from
Popular Abstract in Swedish Dokosahexaensyra (DHA) och eikosapentaensyra (EPA) är omega-3 fettsyror, som har hälsofrämjande effekter. De behöver skyddas, DHA i synnerhet, eftersom de är mycket känsliga för oxidation. Flera lipider som innehöll DHA utvärderades med avseende på lipidernas möjlighet att skydda DHA mot peroxidation genom att använda en HPLC metod som utvecklades som en del av detta arDocosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. Several lipids containing DHA were evaluated with respect to the ability of the lipids to protect DHA against peroxidation using an HPLC method developed as part of this research. Furthermore,
Background: Familial clustering of incident prostate cancer and some cancers at other discordant sites has been reported. Less is known about familial clustering of fatal prostate cancer with any fatal discordant cancers. Estimates on familial aggregation based on mortality are free from bias of overdiagnosis. Patients and methods: We used the nationwide Swedish Family-Cancer Database to calculate
Increased serum concentrations of the beta subunit of human chorionic gonadotropin (hCG beta) are associated with adverse prognosis in several cancers. The aim of the present study was to analyse the association between serum hCG beta recurrence, and survival, in patients with colorectal cancer. The concentrations of hCG beta were determined in serum collected preoperatively from 324 patients with
Poly (ethylene-co-vinyl acetate) (EVA)/clay nanocomposites containing two different organoclays with different clay loadings were prepared. The transport of gases (oxygen and nitrogen) through the composite membranes was investigated and the results were compared. These studies revealed that the incorporation of nanoclays in the polymer increased the efficiency of the membranes toward barrier prop
The freezing of monomeric mixtures is known to concentrate solutes in a nonfrozen phase in the area surrounding the ice crystals. The concentration of such solutes is determined by the freezing temperature. Although salts or solvents do not directly react in the polymerization reaction, they do change the composition and properties of the nonfrozen phase. In this study, we investigated the influen
Proteolytic cleavage of the Na+/Ca2+ exchanger (NCX) by calpains impairs calcium homeostasis, leading to a delayed calcium overload and excitotoxic cell death. However, it is not known whether reversal of the exchanger contributes to activate calpains and trigger neuronal death. We investigated the role of the reversal of the NCX in Ca2+ dynamics, calpain activation and cell viability, in alpha-am
The effect of some amphipilic diblock-copolymers and comb-polymers on a balanced Winsor III microemulsion system is investigated with the quaternary system n-octyl-beta-D-glucoside/1-octanol/n-octane/D2O as basis system. The diblock-copolymers are polyethyleneoxide-co-polydodecenoxide (PEOx PEDODOy ) and polyethyleneoxide-co-polybutyleneoxide (PEO (x) PEBU (y) ), constituted of a straight chain hy
alpha(1)-Microglobulin is a 26-kDa glycoprotein synthesized in the liver, secreted to the blood, and rapidly distributed to the extravascular compartment of all tissues. Recent results show that alpha(1)-microglobulin has heme-binding and heme-degrading properties and it has been suggested that the protein is involved in the defense against oxidation by heme and reactive oxygen species. In the pre
Propofol, an intravenous anaesthetic, has been shown to interact with the beta -subunit of the gamma -amino butyric acid(A) (GABA(A) ) receptor and also to cause changes in [Ca2+ ](i) . The GABA(A) receptor, a suggested target for anaesthetics, is known to be regulated by kinases. We have investigated if tyrosine kinase is involved in the intracellular signal system used by propofol to cause anaes
The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for fuel ethanol production is inhibited by 5-hydroxymethyl furfural (HMF), a furan derivative which is formed during the hydrolysis of lignocellulosic materials. The inhibition can be avoided if the yeast strain used in the fermentation has the ability to reduce HMF to 5-hydroxymethylfurfuryl alcohol. To enable the identi
In this time-course study the levels of different reactive species, especially those of nitric oxide and peroxynitrite were determined in streptozotocin-induced diabetic rat tissues at different time-points after the onset of the disease, before the development of histopathological damages. Significantly higher steady state free radical concentrations were found in the liver 3 weeks after the onse

In the mid 2000s the oil and gas industry was hit by what might be best described as a ‘wall of cash’ as oil prices successively reached new record levels and access to external financing improved greatly. In this article we investigate what this sudden abundance of liquidity implied for the investment-cash flow relationship, the interpretation of which continues to generate controversy in the fin
CONCLUSIONS: The results of the present study suggest that the pancreas and parotid glands both respond with hypoplasia during absence of food in the digestive tract and with hyperplasia following pancreatico-biliary diversion (PBD). Factors other than cholecystokinin (CCK) are, however, involved in the effects on the parotid glands, since infusion of CCK-8S and devazepide was without influence. B
This project was carried out as a series of concerts and workshops of organ improvisation with six professional performers. The purpose was to further explore experiences made in the artistic research project Rethinking organ improvisation, which pointed at how improvisation differs in musical character and function between different performance contexts.Our aims were to •rethink improvisation in
Background: Treatment with omega-3 fatty acids and fenofibrates reduces serum triglyceride levels, but few studies have compared the effect of these agents on liver fat. Objective: The aim of the EFFECT I trial (NCT02354976) was to determine the effects of free omega-3 carboxylic acids (OM-3CA) and fenofibrate on liver fat in overweight or obese individuals with non-alcoholic fatty liver disease a
Data from experiments on the phenomenon of recognition failure of recallable words show moderate dependence between recognition and recall. TECO, a connectionist theory, is proposed to account for the phenomenon. Cued recall is assumed to be cued with the cue word and the event. Recognition is assumed to be cued with the event and the copy cue. Moderate dependence is predicted because recall and r
Background: Providing equal access to health care is an important objective in most health care systems. It is especially pertinent in systems like the Swedish primary care market, where private providers are free to establish themselves in any part of the country. To improve equity in access to care, 15 out 21 county councils in Sweden have implemented risk-adjusted capitation based on the Care N
