Raman spectroscopy of mini-CAST soot with various fractions of organic compounds: Structural characterization during heating treatment from 25 °C to 1000 °C
Soot particles undergo considerable changes in composition, morphology, as well as in internal structure during formation from the incipient particles to more mature aggregates, and still there is a lack of understanding of these mechanisms. In this study, soot produced by a mini-CAST soot generator was probed using Raman spectroscopy with focus on soot with large variation in size and fraction of
Soot Optical Band Gap Evaluated Through In-Situ And Ex-Situ Measurements As Tracer Of Soot Evolution In Premixed Flames : Soot Optical Band Gap Evaluated Through In-Situ And Ex-Situ Measurements As Tracer Of Soot Evolution In Premixed Flames
The optical band gap has been used considerably in evaluating carbon network structures in terms of sp 2 /sp 3 sites and size of aromatic clusters. However, optical band gap determination of soot particles from optical measurements is complex due to the effects of other species including organic compounds, and the contribution of absorption from organics to the total soot absorption in the UV/visi
Degradation of chylomicron remnant cholesteryl ester by rat hepatocyte monolayers. Inhibition by chloroquine and colchicine
Desaturation and chain elongation of n - 3 and n - 6 polyunsaturated fatty acids in the human CaCo-2 cell line
Human CaCo-2 cells were incubated with [14C]linoleic (18:2(n - 6)), [14C]linolenic (18:3(n - 3)) and [3H]eicosapentaenoic acid (20:5(n - 3)), and the interconversion of the radioactive fatty acids to higher homologues and their acylation into triacylglycerols (TG) and phospholipids were examined. An active conversion of [14C]18:3 to [14C]20:5 and [14C]docosapentaenoic acid (22:5(n - 3)) and of [3H
What do healthcare professionals need to turn risk models for type 2 diabetes into usable computerized clinical decision support systems? Lessons learned from the MOSAIC project
Background: To understand user needs, system requirements and organizational conditions towards successful design and adoption of Clinical Decision Support Systems for Type 2 Diabetes (T2D) care built on top of computerized risk models. Methods: The holistic and evidence-based CEHRES Roadmap, used to create eHealth solutions through participatory development approach, persuasive design techniques
Delta-6-desaturase and delta-5-desaturase in human Hep G2 cells are both fatty acid interconversion rate limiting and are upregulated under essential fatty acid deficient conditions
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
Analysis of the genetically tractable crustacean Parhyale hawaiensis reveals the organisation of a sensory system for low-resolution vision
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
Groundwater depletion estimated from GRACE : A challenge of sustainable development in an arid region of Central Asia
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
A role for hepatic lipase in chylomicron and high density lipoprotein phospholipid metabolism
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

Health-related quality of life and glycaemic control among adults with type 1 and type 2 diabetes - A nationwide cross-sectional study
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

Arachidonic acid absorption in human jejunum in organ culture : effects of ethanol
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
Bile but not chyle lipoprotein is an important source of arachidonic acid for the rat small intestine
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
Absorption and incorporation into tissue lipids of 3H-arachidonic- and 14C-linoleic acid : effects of ethanol in jejunal tissue cultures and in vivo
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
Var finns den oberoende professorn?
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 mixed endocrine adrenal tumour causing steatorrhoea
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
The Impact of Lake Water Quality on the Performance of Mature Artificial Recharge Ponds
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
Ärade Statsminister! Breven till statsministern om den ekonomiska politiken
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
