Previous work has shown that amylose (AM) can cross-link hydrophobically modified polymers by inclusion complexation, whereby thermoreversible cold-setting gels are formed. In this work, the competition between AM and cyclodextrin (CD) for the formation of inclusion complexes with hydrophobically modified hydroxyethyl cellulose (HMHEC) is investigated. A detailed study of viscosity, NMR self-diffu
Simultaneous saccharification and fermentation of wood to ethanol has often been claimed to be less sensitive to infection than separate hydrolysis and fermentation. A previous study has shown that this was not the case. In the present study the influence of different parameters in SSF, such as cell concentration, nutrient composition and inclusion of the liquid from pretreatment, on the ethanol y
The best predictor of good outcome after cardiac arrest is awakening from coma. The longer it takes to regain consciousness, the greater the risk of permanent brain injury. A reliable neurological assessment could previously be performed on day 3 after arrest; absence of or a stereotypic motor reaction to pain and absence of cranial nerve reflexes were reliable predictors of poor outcome, but this
Objective: No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. Method: An index capturing employment, accommodation and livin
The aim of this study was to explore community perceptions about child sexual abuse in Tanzania. Thirteen focus group discussions were conducted with adult community members. The core category, children's rights challenged by lack of agency, was supported by eight categories. Aware but distressed portrayed feelings of hopelessness, lack of trust in the healthcare and legal systems reflected percei
Phylogenetic approaches are indispensable in any comparative molecular study involving multiple species. These approaches are in increasing demand as the amount and availability of DNA sequence information continues to increase exponentially, even for organisms that were previously not extensively studied. Without the sound application of phylogenetic concepts and knowledge, one can be misled when
Unlike many nanomaterials, nanocrystalline cellulose (CNC) is not synthesized from molecular or atomic components but rather extracted from naturally occurring cellulose. Undoubtedly, the exploitation of CNCs will become a bridge between nanoscience and natural resource products, which could play a major role in reviving the forest industry. In this work, CNC was successfully extracted from unusua
Chemical plasmid DNA (pDNA) gels were prepared by a cross-linking reaction with ethylene glycol diglycidyl ether (EGDE). Fluorescence microscopy (FM) and scanning electron microscopy (SEM) images of pDNA gels are reported. For the first time, the pDNA gels have been investigated with respect to their swelling in aqueous solution containing different additives, such as metal ions, polyamines, polyc
The stem of Agave tequilana Weber is used to obtain fructans. Reports on the potential prebiotic activity of agave fructans as ingredients are scarce. The aim of this study was to evaluate the indigestible fraction (IF) content and the short chain fatty acid production (SCFA) from in vitro fermentation of: Native-agavefructans (NAF), agave-dietary-fiber (ADF), high-performance-fructans (HPF), both
Larsson, M. R., Bäckström, M., Michel, P.-O. & Lundh, L.-G. (2010). The stability of alexithymia during work in a high-stress environment: A prospective study of Swedish peacekeepers serving in Kosovo. Scandinavian Journal of Psychology. We applied a prospective design to reinvestigate the issue whether the sub-domains of alexithymia could be considered stable traits or distress-related states
Particles of RuSeMo and RuSnMo have been produced by ball milling; they present catalytic activity towards the oxygen reduction reaction (ORR) in acid media. A Tafel slope close to 120 mV/dec was found for both materials. Their morphology was first characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and TEM images reveal particles in the sub-micromet
Background: A number of single nucleotide polymorphisms (SNPs) have been associated with broadband ultrasound attenuation (BUA) and speed of sound (SOS) as measured by quantitative ultrasound (QUS) at the calcaneus in the Framingham 100K genome-wide association study (GWAS) but have not been validated in independent studies. The aim of this analysis was to determine if these SNPs are associated wi
The stability of accelerated electron beams produced by self injection of plasma electrons into the wakefield driven by a laser pulse guided inside capillary tubes is analyzed statistically in relation to laser and plasma parameters, and compared to results obtained in a gas jet. The analysis shows that reproducible electron beams are achieved with a charge of 66 pC +/- 11%, a FWHM beam divergence
The aim of this study was to investigate the possibility to produce novel powder materials based on chemically modified starch granule stabilized Pickering oil-in-water (O/W) emulsions. This study also investigated the effect of partial starch gelatinization in situ, dispersed phase type (two oil types with different melting points), freezing method and thawing, and freeze-drying and rehydrating o
Popular Abstract in Swedish Diabetes, i alla dess olika former, är en allvarlig sjukdom. Typ 1 diabetes är av autoimmun härkomst, då kroppen eget immunförsvaret attackerar och förstör β-cellerna i bukspottkörteln. Dessa celler producerar insulin som hjälper kolhydraterna i maten vi äter att komma kroppens celler till godo. Sverige har världens näst högsta antal nya insjuknanden, bara Finland har fThe role of miRNAs in pancreatic islets and β-cell function and in the development of diabetes in human and rodents have been investigated in this thesis. Dicer1 was specifically deleted in vivo in pancreatic β-cells under the RIP-promoter in mice. The results show that disruption of miRNAprocessing in mouse pancreatic β-cells, while compatible with β-cell development, leads to defective insulin-s
Background: Previous research has focused exclusively on weight loss or weight maintenance following weight loss, i.e. secondary weight maintenance (SWM). The long-term results of SWM have been modest, suggesting that preventing initial weight gain among normal weight or overweight individuals, i.e. primary weight maintenance (PWM), may be more successful. The aim of this study was to compare the
Nitrogen leaching from boreal and temporal forests, where normally most of the nitrogen is retained, has the potential to increase acidification of soil and water and eutrophication of the Baltic Sea. In parts of Sweden, where the nitrogen deposition has been intermediate to high during recent decades, there are indications that the soils are close to nitrogen saturation. In this study, four diffe
Factor I (FI) is a serine protease that inhibits the complement system by cleaving activated C3 and C4 complement proteins, in the presence of cofactors. Mutations in the gene coding for FI have been identified in complete FI deficient- and atypical hemolytic uremic syndrome (aHUS) patients. The mutations were introduced in recombinantly expressed proteins, purified and analyzed in functional ass
The free volume and crystallization behaviour of poly(ethylene naphthalate) (PEN) treated in pressurized carbon dioxide was studied, using Positron Annihilation Lifetime Spectroscopy (PALS) and Differential Scanning Calorimetry (DSC). PALS probes the values of free volume cavity sizes in materials, thus making it possible to investigate the effect of pressurized carbon dioxide treatment on free vo
