Essential fatty acids are interconverted by desaturases and elongases to eicosanoid precursors. In essential fatty acid deficiency (EFAD) an increased hepatic interconversion of linoleic acid (18:2) to arachidonic acid (20:4n-6) has been demonstrated in vivo. We now cultured Hep G2 cells under EFAD conditions. 20:3n-6 appeared in EFAD cells, but also in controls. After adding 14C-18:2 to the mediu
Background: Arthropod eyes have diversified during evolution to serve multiple needs, such as finding mates, hunting prey and navigating in complex surroundings under varying light conditions. This diversity is reflected in the optical apparatus, photoreceptors and neural circuits that underpin vision. Yet our ability to genetically manipulate the visual system to investigate its function is large
Under climate change and increasing water demands, groundwater depletion has become regional and global threats for water security, which is an indispensable target to achieving sustainable developments of human society and ecosystems, especially in arid and semiarid regions where groundwater is a major water source. In this study, groundwater depletion of 2003-2016 over Xinjiang in China, a typic
The rate of removal of phosphatidylethanolamine and phosphatidylcholine from the plasma of rats treated with antiserum to hepatic lipase was measured. The hepatic lipase antiserum was injected intravenously into animals prior to injection of 32P-labeled chylomicrons or 32P-labeled high density lipoproteins. In experiments in which 32P-labeled chylomicrons were injected, antiserum treatment inhibit
Background: Health-related quality of life and glycaemic control are some of the central outcomes in clinical diabetes care and research. The purpose of this study was to describe the health-related quality of life and assess its association with glycaemic control in adults with type 1 and type 2 diabetes in a nationwide setting. Methods: In this cross-sectional survey, people with type 1 (n = 247
Human jejunal tissue obtained by peroral biopsy was cultured in control medium and in medium containing 100 mmol l-1 ethanol. Subsequently, the incorporation and metabolism of [3H]-arachidonic and [14C]-linoleic acid were evaluated. Of the two fatty acids a significantly higher amount of [3H]-arachidonic acid was incorporated into phospholipids and more [14C]-linoleic acid was incorporated into tr
Arachidonic acid (AA) functions as a structural component, eicosanoid precursor and surface material for chylomicron production in the gastrointestinal tract. The origin of this AA is poorly characterized. [3H]AA labelled chylomicrons and [14C]AA albumin-FFA were injected intravenously into biliary diverted rats and controls. Radioactivity in tissue lipids was measured after different time interva
The effects of ethanol in the rat on the absorption and incorporation of 3H-arachidonic (20: 4, n-6) and 14C-linoleic acid (18:2, n-6) into tissue lipids was examined in jejunal tissue cultures in vivo. The pattern of incorporation earlier seen in the small intestine in vivo, ie. a preferential incorporation of 3H-20: 4 in comparison to 14C-18: 2 into phospholipids (PL), particularly phosphatidyle
Ett generellt problem för professorn är att finna en lämplig avvägning mellan rollen som oberoende bedömare av samhällsutvecklingen och rollen som expert eller konsult åt externa uppdragsgivare. Detta dilemma diskuteras här med utgångspunkt från den växande kopplingen mellan professorskåren inom nationalekonomi och den offentliga sektorn under de senaste 10–15 åren. Någon enkel lösning på motsättn
A 60 year old man developed steatorrhoea, weight loss, mild diabetes mellitus, labile hypertension and limb cramps. Raised plasma concentrations of catecholamines, particularly noradrenaline and a computed tomography-scan showing an adrenal tumour strongly suggested a pheochromocytoma. Adrenoreceptor blockade reversed the symptoms, decreased faecal fat, and increased duodenal trypsin to normal con
Artificial groundwater recharge is commonly used for drinking water supply. The resulting water quality is highly dependent on the raw water quality. In many cases, pre-treatment is required. Pre-treatment improves the drinking water quality, although how and to what extent it affects the subsequent pond water quality and infiltration process, is still unknown. We evaluated two treatment systems b
Här granskas ett stickprov på cirka ett halvt tusen brev skrivna till statsministern under 1992–95 i syfte att kartlägga brevskrivarnas uppfattning om hur svensk ekonomi och ekonomisk politik fungerar. Urvalet omfattar såväl brev adresserade till en borgerlig statsminister, Carl Bildt, som till en socialdemokratisk, Ingvar Carlsson.Av breven framgår att rättvisa och fördelning är långt mer central
There is a growing political consensus in the European Union (EU) to move away from the current resource intensive “linear” economic system, towards an innovative system aiming at closing material loops – the so-called circular economy. An array of new policy proposals targeting all stages of the life-cycle of a product are needed to facilitate the transition to a circular economy in Europe. While
Under 1900-talet har målen, medlen, institutionerna samt strategin för penning- och finanspolitiken befunnit sig i ständig omvandling, främst orsakad av djupa ekonomiska kriser. Detta mönster antyder att även 2000-talet kommer att se fundamentala omprövningar i stabiliseringspolitiken när framtidens kriser träffar svensk ekonomi. 1900-talets stabiliseringspolitik har dominerats av guldmyntfoten me
Den nya ekonomin har inspirerat till djärva utsagor om vår ekonomiska framtid. Här granskas fem sådana utifrån ett historiskt perspektiv. Hur påverkar den nya ekonomin följande fem fenomen: konjunkturcykeln, de ekonomiska kriserna, inflationen, stabiliseringspolitiken samt den svenska modellen? Svaren är förvisso preliminära men pekar på att den nya ekonomin på vissa områden inte leder till någon
Mellan 1873 och 1924 ingick Sverige i en valutaunion tillsammans med Danmark och Norge – den skandinaviska myntunionen (SMU) byggd på den gemen- samma valutaenheten – kronan. Denna artikel belyser tillkomsten, effekterna och upplösningen av den skandinaviska myntunionen samt jämför den med EMU. Ett medlemskap i EMU kräver mer av ekonomisk och politisk anpassning än vad ett medlemskap i SMU gjorde
