Ethanol exposure increases expression of c-jun and junD in human neuroblastoma cells
The aim of this study was to investigate the effect of ethanol exposure on the expression of fos and jun genes. Exposure of human neuroblastoma SH-SY5Y cells to ethanol for 2-4 days caused a dose-dependent increase in c-jun and junD mRNA levels, whereas mRNAs for c-fos, fosB and junB were not detectable in control or ethanol-treated cells. Four days of ethanol exposure also enhanced the AP-1 bindi
Activation of silenced transgene expression in neural precursor cell lines by inhibitors of histone deacetytation
Background Ex vivo gene therapy in the central nervous system (CNS) holds great promise for diseases such as the neurodegenerative disorders. However, achieving stable, long-term transgene expression in grafted cells has proven problematic. This study reports the establishment of an in vitro model of transgene down-regulation in cells grafted to the CNS using the immortalized neural progenitor cel

Headache in patients with cervical radiculopathy: a prospective study with selective nerve root blocks in 275 patients.
Since many years we routinely use diagnostic selective nerve root blocks (SNRB) at our department when evaluating patients with cervical radiculopathy. Frequently patients who also presented with headache reported that the headache disappeared when the nerve root responsible for the radicular pain was blocked with local anaesthetics. Headache has been described as a companioning symptom related to

Yersinia enterocolitica serum resistance proteins YadA and Ail bind the complement regulator C4b-binding protein
Many pathogens are equipped with factors providing resistance against the bactericidal action of complement. Yersinia enterocolitica, a Gram-negative enteric pathogen with invasive properties, efficiently resists the deleterious action of human complement. The major Y. enterocolitica serum resistance determinants include outer membrane proteins YadA and Ail. Lipopolysaccharide (LPS) O-antigen (O-a
Bordetella pertussis binds to human C4b-binding protein (C4BP) at a site similar to that used by the natural ligand C4b
Human complement regulators are important targets for pathogenic microorganisms. In one such interaction, Bordetella pertussis binds human C4b-binding protein (C4BP), a high-molecular-weight plasma protein that acts as inhibitor of the classical pathway of complement activation. At least two different B. pertussis surface components, one of which is the virulence factor filamentous hemagglutinin (
Subsidy from the Detrital Food Web, but Not Microhabitat Complexity, Affects the Role of Generalist Predators in an Aboveground Herbivore Food Web
The activity and density of generalist predators, such as carabid beedes, rove beedes and spiders, may increase in response to: (1) increased availability of prey from the belowground subsystem and/ or (2) enhanced complexity of aboveground vegetation. Organic farming practices support decomposer populations and enhance habitat complexity due to an increased weed density. A response by generalist
Phosphatase activity of extra-radical arbuscular mycorrhizal hyphae: A review.
Phosphatase activity of arbuscular mycorrhizal (AM) fungi has attracted attention in three fairly distinct domains: intracellular enzymes with defined metabolic functions that have been studied in intraradical hyphae, histochemical staining of alkaline phosphatase as an indicator of fungal activity measured both intra- and extraradically, and extracellular activity related to mineralization of org
Nuchal cord in post-term pregnancy - relationship to suspected intrapartum fetal distress indicating operative intervention.
Abstract Color Doppler Ultrasound was performed on 202 post-term pregnancies to detect the presence of a nuchal cord. A nuchal cord was diagnosed if the umbilical cord could be followed 360 degrees around the fetal neck. The results were not disclosed to the managing obstetrician, midwife, and patient. The perinatal outcome was analyzed according to Apgar score, umbilical cord artery and vein pH a
Safety of the probiotic strain Lactobacillus plantarum DSM 9843 (strain 299v) in an endocarditis animal model
Objective: Lactobacilli are often considered to be beneficial or non-pathogenic to man, with small numbers of human infections being reported, including septicemia and infective endocarditis. To verify the safety of Lactobacillus plantarum DSM 9843 (=strain 299v) administration, we used a well-known endocarditis animal model. Design: Experimental study using Sprague-Dawley rats. Setting: Universit

Modeling drying and energy performance of industrial through-dryers
A model of an industrial through-dryer for production of tissue paper was developed. The model can be used to predict the performance of a dryer section of an industrial through-drying machine consisting of one or more through-drying rolls separated by free draw sections. Roll diameters, wrap angles, machine speed, basis weight, initial paper moisture ratio, operating pressure differentials, dryin
A Jurassic (Pliensbachian) flora from Bornholm, Denmark - a study of a historic plant-fossil collection at Lund University, Sweden
A historic collection of plant fossils from the Baga Formation, Bornholm, Denmark registered at the Lund University is reviewed and found to be dominated by ferns with subsidiary Ginkgoales, Coniferales, Bennettitales and Equisitales. Ten genera are represented, of which six can be confidently identified to species level. The Baga Formation flora is most similar in age to the flora of the Middle J
A Long-Term Perspective on Person-Environment Fit and ADL Dependence Among Older Swedish Adults.
Purpose: This study described person–environment (P–E) fit and activities of daily living (ADLs) among older adults, and it explored the relationship between P–E fit and ADL dependence, testing Lawton's docility hypothesis at two points in time. Design and Methods: From a random sample of individuals aged 75–84 living in a Swedish municipality, 72 persons were available for baseline and follow-up

A cinefluorographic study of the temporal organization of articulator gestures: Examples from Greenlandic
Movement data on articulator gestures in West Greenlandic are presented in order to elucidate principles of articulator coordination, especially the domain of coarticulation (as distinct from the domain of assimilation), the handling of conflicting demands on articulators, and the relation of vowels to consonants. The present data are consistent with results previously obtained from Swedish and Bu
Arsenic trioxide-induced death of neuroblastoma cells involves activation of Bax and does not require p53.
Factors affecting time to pregnancy
BACKGROUND: Both lifestyle factors and occupational and environmental factors have been suggested to affect the female reproductive system. In the present study, the separate and joint effects of several such factors are investigated. METHODS: Information on time to pregnancy (TTP) was available for 1578 women randomly selected from the general Swedish population. The information was collected ret
