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

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

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)-

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

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

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

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

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

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

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

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

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

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

Theoretical and experimental results for the 2s(2) S-1(0)-2s2p P-3(1) intercombination line in beryllium-like ions are reviewed and revised, and some new data are presented. The uncertainty in the resulting transition rate is estimated, by using convergence of systematic calculations, accuracy of energy properties and theoretical tests, and is used to evaluate the accuracy of present and other cal

Between 1978 and 2001, 22 patients were diagnosed with occupation-related allergic contact dermatitis from isocyanates and/or polyurethanes in our clinic . 13 had a positive reaction to the isocyanates, of whom 10 also reacted to diaminodiphenylmethane (MDA), which is used in the production or processing of isocyanates and polyurethanes; 9 reacted only to MDA. The object of the present study was t

A model was developed to describe the droplet formation mechanism in membrane emulsification from the point of view of Gibbs free energy with the help of the Surface Evolver, which is an interactive finite element program for the study of interfaces shaped by Surface tension. A program to test the model was written and run which allows the user to track the droplet shape as it grows, to identify t

We present a calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT). The scheme is applied to uranium and nitrogen ions using a specific set of EBIT operating parameters. The calculation results are compared to the experimental data. Rates for the individual atomic processes in

Purpose of review Recently, genome-wide genetic screening of common DNA sequence variants has proven a successful approach to identify novel genetic contributors to complex traits. This review summarizes recent genome-wide association studies for lipid phenotypes, and evaluates the next steps needed to obtain a full picture of genotype-phenotype correlation and apply these findings to inform clini
