Psyllium and fat in diets differentially affect the activities and expressions of colonic sphingomyelinases and caspase in mice.
Dietary fibre and fat affect colonic tumourigenesis and inflammation. Sphingomyelin metabolism may have implications for the pathogenesis of colonic tumours and ulcerative colitis. The present study examined the effects of psyllium and fat on the enzymes responsible for sphingomyelin metabolism and apoptosis in the colon. Mice were fed control, psyllium-containing (100 g/kg), high-fat (313 g/kg, 5
Pure rotational coherent anti-Stokes Raman spectroscopy in mixtures of CO and N-2
We present a model for quantitative measurements in binary mixtures of nitrogen and carbon monoxide by the use of dual-broadband rotational coherent anti-Stokes Raman spectroscopy. The model has been compared with experimental rotational coherent anti-Stokes Raman scattering spectra recorded within the temperature range of 294-702 K. Temperatures and concentrations were evaluated by spectral fits

Guided wave approach for concrete pavement thickness estimation
The basis of a new non-destructive method for concrete pavements is described. The method uses a hybrid approach that combines frequency domain (impact-echo) and time domain (seismic) data. The equipment and data interpretation for the hybrid approach are described. The dynamic response data are interpreted in terms of guided plate wave (Lamb wave) theory, which are shown to follow the S, Lamb mod
Migration of cells into and out of peripheral nerve isografts in the peripheral and central nervous systems of the adult mouse
Peripheral nerve (PN) isografts provide a favourable environment for axon regeneration after peripheral and central nervous system (CNS) injury, but definitive information on the extent of cellular intermixing between donor and host tissues is lacking. We wished to compare migration patterns in fresh and predegenerate PN grafts, and also compare the extent of cell migration after transplantation t
Independent checking of the delivered dose for high-energy X-rays using a hand-held PC
Background and purpose: The requirements on the delivered dose in radical radiation therapy are extremely high. The dose should be within a few percent and also delivered with high accuracy in space. Vendors and users have successfully managed to implement radiation therapy systems, which are able to achieve these demands with high accuracy and reproducibility. These systems include computerized t
Endothelium-derived prostanoids reduce 5-hydroxytryptamine-induced contraction in the human uterine artery
The contribution of endothelium-linked mechanisms to the contraction induced by 5-hydroxytryptamine (5-HT) was investigated in the isolated human uterine artery. 5-HT contracted the uterine artery concentration-dependently. Removal of the endothelium or treatment with the cyclooxygenase inhibitor indomethacin potentiated the contractile response to 5-HT. The nitric oxide synthase inhibitor L-N(G)-
Vegetation, climatic changes and net carbon sequestration in a North-Scandinavian subarctic mire over 30 years
This study deals with changes in the plant cover and its net carbon sequestration over 30 years on a subarctic Sphagnum-mire with permafrost near Abisko, northernmost Sweden, in relation to climatic variations during the same period. Aerial colour infrared images from 1970 and 2000 were compared to reveal changes in surface structure and vegetation over the whole mire, while the plant populations
The GRACILE syndrome, a neonatal lethal metabolic disorder with iron overload
GRACILE syndrome (Fellman syndrome, MIM 603358), an autosomal recessive metabolic disorder of the Finnish disease heritage, has been diagnosed in 25 infants of 18 families. The incidence is at least 1/47,000 in Finland. The main findings are fetal growth retardation, Fanconi type aminoaciduria, cholestasis, iron overload (liver hemosiderosis, hyperferritinemia, hypotransferrinemia, increased trans
Colour photographs for estimation of heterocyclic amine intake from fried pork chops of different RN genotypes indicate large variations
A questionnaire complemented with colour photographs was used to obtain information on dietary practices and preferences regarding home-prepared pork chops in a small (n = 151) sample of Swedish consumers. The results from the questionnaire were combined with analytical results from meat of different RN genotypes, and showed that fried chops from a pig that was carrying the RN- allele (high glycog
Sonographic Investigation of the Rectoanal Inhibitory Reflex: A Qualitative Pilot Study in Healthy Females.
PURPOSE: The rectoanal inhibitory reflex has been studied using various methods, e. g., anometry and electromyography. The aim of this study was to apply ultrasound for direct visualization of the rectoanal inhibitory reflex. METHOD: The rectoanal inhibitory reflex was induced in ten healthy females (age range, 21 - 55 years) by injection of small amounts of water (7, 12, and 20 ml), into the rect
Structural basis of Wiskott-Aldrich syndrome causing mutations in the WH1 domain
Short-Term Outcomes of Trapeziometacarpal Artelon Implant Compared With Tendon Suspension Interposition Arthroplasty for Osteoarthritis: A Matched Cohort Study.
PURPOSE: To compare the short-term efficacy of the Artelon trapeziometacarpal (TMC) implant with that of total trapeziectomy and abductor pollicis longus (APL) tendon suspension interposition arthroplasty in TMC osteoarthritis. METHODS: A single-center matched cohort study was designed. The Artelon cohort comprised 13 consecutive patients (10 women, 3 men; mean age, 54 years) operated on with Arte

Certified reference material for radionuclides in fish flesh sample IAEA-414 (mixed fish from the Irish Sea and North Sea)
A certified reference material (CRM) for radionuclides in fish sample IAEA-414 (mixed fish from the Irish Sea and North Seas) is described and the results of the certification process are presented. Nine radionuclides (K-40, Cs-137, Th-232, U-234, U-235, U-238, Pu-238, Pu239+240 and Am-241) were certified for this material. Information on massic activities with 95% confidence intervals is given fo
Super-shell structure in harmonically trapped fermionic gases and its semi-classical interpretation
It was recently shown in self-consistent Hartree-Fock calculations that a harmonically trapped dilute gas of fermionic atoms with a repulsive two-body interaction exhibits a pronounced super-shell structure: the shell fillings due to the spherical harmonic trapping potential are modulated by a beat mode. This changes the 'magic numbers' occurring between the beat nodes by half a period. The length
The experience of quality of life among older people
Although quality of life has been in the focus of attention for over a decade there are few studies available investigating, how the old and the oldest old experience their quality of life or what quality of life actually means for them? To illuminate this, eleven in-depth interviews were conducted with six women and five men (80+) living in their home. An interpretative hermeneutic phenomenologic
Transgenic mice expressing a Huntington's disease mutation are resistant to quinolinic acid-induced striatal excitotoxicity
Huntington's disease (HD) is a hereditary neurodegenerative disorder presenting with chorea, dementia, and extensive striatal neuronal death. The mechanism through which the widely expressed mutant HD gene mediates a slowly progressing striatal neurotoxicity is unknown. Glutamate receptor-mediated excitotoxicity has been hypothesized to contribute to the pathogenesis of HD. Here we show that trans
Molecular structure and tissue distribution of matrilin-3, a filament-forming extracellular matrix protein expressed during skeletal development
Matrilin-3 is a recently identified member of the superfamily of proteins containing von Willebrand factor A-like domains and is able to form hetero-oligomers with matrilin-1 (cartilage matrix protein) via a C-terminal coiled-coil domain. Full-length matrilin-3 and a fragment lacking the assembly domain were expressed in 293-EBNA cells, purified, and subjected to biochemical characterization. Reco
