Short-chain fatty acid content in the hindgut of rats fed various composite foods and commercial dietary fibre fractions from similar sources

The fermentability of indigestible carbohydrates and content of short-chain fatty acids along the hindgut of rats were investigated using plant materials of importance in the Swedish diet (instant potato powder, apples and oat flakes). Results with the composite food products were compared with commercial fibre fractions obtained from similar sources, ie potato fibre, apple pectin and beta-glucan-

Spacer and anchor effects on the electronic coupling in ruthenium-bis-terpyridine dye-sensitized TiO2 nanocrystals studied by DFT

Structural and electronic properties of TiO2 nanoparticles sensitized with a set of RuII(tpy)(2) based dyes have been investigated using density functional theory (DFT) calculations combined with time-dependent (TD) DFT calculations. The effects of carboxylic and phosphonic acid anchor groups, as well as a phenylene spacer group, on the optical properties of the dyes and the electronic interaction

Bartonella spp. seroprevalence in healthy Swedish blood donors

Serum samples were collected from healthy blood donors in 5 regions in Sweden in 1999, i.e. from the local Blood Centres (collecting facilities) in Boden, Jonkoping, Lund, Skovde, and Uppsala. In total, 498 serum samples (63% males, 37% females) were received and tested by immunofluorescence assay for antibodies against B. elizabethae, B. grahamii, B. henselae (Houston-1), B. henselae (Marseille),

Shoulder dystocia and brachial plexus injury: a case-control study

Objective and Background. To evaluate risk factors for shoulder dystocia and brachial plexus injury using a case-control study at the departments of obstetrics and gynecology at the four largest hospitals in southern Sweden. All cases of shoulder dystocia between 1987 and 1993 inclusive were identified. For each case, two control infants with similar birthweight (+/- 100 g) and identical year of b

One-year low-dose erythromycin treatment of persistent chronic sinusitis after sinus surgery: clinical outcome and effects on mucociliary parameters and nasal nitric oxide.

OBJECTIVE: In 17 patients with chronic sinusitis persistent after sinus surgery, long-term, low-dose erythromycin therapy was tested. The aim of the investigation was to study the clinical outcome and effects on nasal nitric oxide (NO), ciliary beat frequency (CBF), and mucociliary transport (saccharine transit time). STUDY DESIGN AND SETTING: We conducted a prospective open study at a tertiary te

Tobacco smoking increases dramatically air concentrations of endotoxin.

We used a mass spectrometry-based assay for identifying the endotoxin (lipopolysaccharide, LPS) marker (R)-3-hydroxytetradecanoic acid in cigarette smoke particles and found that smoking involved inhalation of 17.4 pmol of endotoxin per each smoked cigarette. Indoor exposure to environmental tobacco smoke (ETS) entailed inhalation of 12.1 pmol of LPS/m3 air, an amount that was 120 times higher tha

Magnetism of ordered Sm/Co(0001) surface structures

The epitaxial system Sm/Co(0001) was studied for Sm coverages up to 1 monolayer (ML) on top of ultrathin Co/W(110) epitaxial films. Two ordered phases were found for 1/3 and 1 ML Sm, respectively. The valence state of Sm was determined by means of photoemission and magnetic properties were measured by magneto-optical Kerr effect. We find that 1 ML Sm causes a strong increase of the coercivity with

Tumour morphology--interplay between chromosome aberrations and founder cell differentiation.

Studies of haematological neoplasms have shown that alterations in structure and/or expression of transcription factor genes may play a crucial role for transforming stem cells or progenitor cells into malignant cells. These mutations typically arise through balanced translocations and appear to induce a block in cellular differentiation. The impact of the transforming mutation is highly dependent

Integration between abutting retinas: Role of glial structures and associated molecules at the interface

PURPOSE. Integration between subretinal grafts and the host retina is limited in part by the presence of a barrier at the graft-host interface. This study was conducted to identify factors that may contribute to this barrier, by examining the distribution of glial structures and associated molecules in different setups of overlapping retinal pieces. METHODS. Neuroretinal tissue derived from mice t

Muscular dystrophies involving the dystrophin-glycoprotein complex: an overview of current mouse models

The dystrophin-glycoprotein complex (DGC) is a multisubunit complex that connects the cytoskeleton of a muscle fiber to its surrounding extracellular matrix. Mutations in the DGC disrupt the complex and lead to muscular dystrophy. There are a few naturally occurring animal models of DGC-associated muscular dystrophy (e.g. the dystrophin-deficient mdx mouse, dystrophic golden retriever dog, HFMD ca

Undervisa mot våld. Attityder, läromedel, arbetssätt

Syftena med det i projektet beskrivna inlärnings- experimentet var att studera barns attityder till våld och att med ett attitydtest undersöka effekterna av undervisning mot våld. Samtidigt jämfördes individuellt arbete och grupparbete samt användningen av tre slag av läromedel: texter, bilder och muntliga uppgifter. Både process- och produktvariabler undersöktes. Deltagare var elever i åldrarna 1The main aim of this study has been to influence the attitudes of students, Grades 4-6, in order that they will become opposed to the use of violence. The entire project was conducted during a full academic 20-credit term, as part of inter- mediate level teachers' training. The purpose of this learning experiment was threefold: 1. To study children's attitudes towards violence. 2. To study the eff
