When solutions of two different polymers are mixed, phase separation often occurs even at low concentrations of polymers. One polymer usually collects in one phase and the other polymer in the other phase. When water is used as solvent, two aqueous, immiscible, phases are obtained. The same holds for aqueous mixtures of a salt and a polymer. Such aqueous two-phase systems (ATPS) are very useful fo
Purpose: The purpose of this study was to explore the importance of local physical tissue support for homeostasis in the isolated retina. Methods: Full-thickness retinal sheets were isolated from adult porcine eyes. Retinas were cultured for 5 or 10 days using the previously established explant protocol with photoreceptors positioned against the culture membrane (porous polycarbonate) or the Mülle
Previous studies of mid-Ordovician limestone in Sweden have shown that over a stratigraphic interval representing a few million years there is a two orders-of-magnitude enrichment in fossil L-chondritic meteorites (empty set = 1-21 cm) and sediment-dispersed extraterrestrial chromite (EC) grains (>63 mu m). This has been interpreted as a dramatic increase in the flux of L-chondritic matter to Eart
Background: Short children born small for gestational age (SGA) are treated with growth hormone (GH) dose based on body size, but treatment may lead to high levels of IGF-I. The objective was to evaluate IGF-I titration of GH dose in contrast to current dosing strategies. Methods: In the North European Small for gestational age study (NESGAS) 92 short pre-pubertal children born SGA were randomised
Pathogens that are maintained by wild birds occasionally jump to human hosts, causing considerable loss of life and disruption to global commerce. Preliminary evidence suggests that climate change and human movements and commerce may have played a role in recent range expansions of avian pathogens. Since the magnitude of climate change in the coming decades is predicted to exceed climatic changes
Background and Purpose: In this multicentre phase I-II trial we evaluated the feasibility and efficacy of capecitabine and oxaliplatin followed by the combination of these two drugs with radiotherapy in patients with locally advanced pancreatic or biliary tract cancer. Material and methods: Thirty-nine patients with inextirpable adenocarcinoma of the pancreas, gallbladder or extrahepatic bile duct
Human galectin-4 is a lectin that is expressed mainly in the gastrointestinal tract and exhibits metastasis-promoting roles in some cancers. Its tandem-repeat nature exhibits two distinct carbohydrate recognition domains allowing crosslinking by simultaneous binding to sulfated and non-sulfated (but not sialylated) glycosphingolipids and glycoproteins, facilitating stabilization of lipid rafts. Cr
Precise geochronology, combined with paleomagnetism on mafic intrusions, provides first-order information for paleoreconstruction of crustal blocks, revealing the history of supercontinental formation and break-up. These techniques are used here to further constrain the apparent polar wander path of the Kaapvaal Craton across the Neoarchean-Paleoproterozoic boundary. U-Pb baddeleyite ages of 2441
BACKGROUND: The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item hearing-specific questionnaire. It was developed with the purpose of evaluating the efficacy of hearing aid rehabilitation. Few psychometric properties have been presented for a Swedish translation of the IOI-HA. Furthermore, previous studies have examined the IOI-HA in mainly sensorineural hearing losses, an
Hydrolysis rate constants of sludge at 35°C, 55°C, and 60°C were found to be 0.32 d-1, 0.44 d-1, and 0.50 d-1, respectively in pilot-scale experiments with digestion of municipal sludge in semi-continuously operated reactors. The hydrolysis rate constants as well as estimated chemical oxygen demand (COD) fractions in the feed were implemented in a mathematical model for anaerobic digestion similar
Anaerobic digestion would enable the energy potential of agricultural crop residues such as ley crops, sugar beet tops and straw to be harnessed in Sweden. These residues are so spread out that full utilisation of the potential by centralised slurry-based technology is difficult, its appearing that simple but effective high-solids reactor systems have a better chance of being economically viable o
Just like other newly introduced concepts such as 'science', 'culture', or 'religion', the widely used Chinese term for 'profession' – zhiye – has been established with its modern meaning only in the course of this century, especially after the foundation of the 'Chinese Society of Vocational Education' by Huang Yanpei in 1917. However, the term itself is not a new one, but is the product of ancie
The aim of this study is to examine the relationship between retailer brand (RB) market shares and consumer prices. Furthermore it investigates whether changes in category price and expenditure are due to changes in customer purchase patterns or changes in relative price levels (price gap) of RBs and national brands (NBs). Data from the market research company GfK's consumer household panel, compr
