Expression of nitric oxide synthase in bladder smooth muscle cells: Regulation by cytokines and L-arginine

Purpose: The expression and regulation of the different isoforms of nitric oxide synthase (NOS) in bladder smooth muscle cells are controversial and to our knowledge have not yet been studied systematically. Therefore, the expression and regulation of NOS were studied in rat bladder smooth muscle cells after stimulation with cytokines, lipopolysaccharide and L-arginine. Materials and Methods: Prim

Investigating the use of Landsat thematic mapper data for estimation of forest leaf area index in southern Sweden

The study aims at investigating the use of Landsat thematic mapper (TM) for mapping leaf area index (LAI) in coniferous and deciduous forests in southern Sweden. LAI has been estimated in the field with optical measurements, allometric equations, and litter-trap data, and empirical relationships between LAI estimates and satellite-measured reflectances have been analysed. Several common vegetation

Telomere terminating with centromere-specific repeats is closely associated with a transposon derived gene in Chironomus pallidivittatus

We provide evidence that centromere-specific 155 bp DNA repeats terminate one pair of telomeres at the telocentric, left end of the short fourth chromosome in Chironomus pallidivittatus. Earlier evidence indicated that all other telomeres are terminated by 340 bp telomere-specific repeats. DNA that borders the 155 bp repeat contains a transcriptionally active 396 codon open reading frame (ORF) a f

Limitations of the pulse-shape technique for particle discrimination in planar Si detectors

Limitations of the pulse-shape discrimination (PSD) technique - a promising method to identify the charged particles stopped in planar Si-detectors - have been investigated. The particle resolution turned out to be basically determined by resistivity fluctuations in the bulk silicon which cause the charge-collection time to depend on the point of impact. Detector maps showing these fluctuations ha

Subduction-flip during Iapetus Ocean closure and Baltica-Laurentia collision, Scandinavian Caledonides

Evidence is presented here from the northern Scandinavian Caledonides for development of an extensional basin of Ashgill to Mid Llandovery age along the Baltoscandian margin immediately prior to Baltica-Laurentia collision. U/Pb multigrain and ion microprobe zircon dating of plagiogranites in the Halti Igneous Complex complement previous baddeleyite and zircon dating of a dolerite dyke, and zircon

Physical activity of subjects aged 50-64 years involved in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Objective: To describe physical activity of participants in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: A cross-sectional analysis of baseline data of a European prospective cohort study. Subjects: This analysis was restricted to participants in the age group 50-64 years, which was represented in all EPIC centres. It involved 236 386 participants from 25 centre

Patterns of Care : Relating Altruism in Sociobiology and the Christian Tradition of Agape

Popular Abstract in Swedish Avhandlingens titel Patterns of Care: Relating Altruism in Sociobiology and the Christian Tradition of Agape kan översättas som Omsorgsmönster: Förhållandet mellan hur altruism förstås i sociobiologin och den kristna agape-traditionen. (Ordet agape är grekiska för kärlek. Sociobiologi är ett naturvetenskapligt forskningsprogram som undersöker socialt beteendes biologisThe purpose of this study is to relate sociobiological theories of altruism to theories within the Christian tradition of agape. Firstly, it discusses the relation between scientific, ethical and theological understandings of altruism, and argues that it is possible to compare discussions of benevolent acts towards others or other-directedness. Such acts are determined in content by the extent an

Kalkmålningarna som retorik [summary: Wall-paintings as rhetoric]

Late medieval wall-paintings are part of sacred rhetoric, intended to convey the moral sense of Christian salvation history to churchgoers. The paintings of Albertus Pictor are studied according to the rhetorical principles set down in Augustine's De doctrina christiana and medieval scriptural interpretation.

Bayesian modelling of spatial data using Markov random fields, with application to elemental composition of forest soil

Spatial datasets are common in the environmental sciences. In this study we suggest a hierarchical model for a spatial stochastic field. The main focus of this article is to approximate a stochastic field with a Gaussian Markov Random Field (GMRF) to exploit computational advantages of the Markov field, concerning predictions, etc. The variation of the stochastic field is modelled as a linear tren

Hyperplasia and hypertrophia in the denervated and distended rat urinary bladder

The parasympathetically denervated and distended rat urinary bladder was found to have increased fourfold in weight when examined 3 weeks postoperatively. Both in muscularis and mucosa of such a bladder the synthesis of proteins, RNA and DNA was increased severalfold. An increase in the polyamines putrescine, spermidine and spermine was also found; these polyamines are usually linked to protein sy

Dietary factors influence the recovery rates of Helicobacter pylori in a BALB/cA mouse model

The aim of this study was to assess the ability of different mouse diets to sustain an H. pylori infection in BALB/cA mice. Four commercially available mouse diets were compared. Experiment 1: Mice were fed the four diets for seven days before infection, infected three times at two-day intervals with 0.1 ml of 10(9) colony-forming units/ml H. pylori cells. H. pylori strains (n = 4) were cultured o

Petrographic classification of middle ordovician fossil meteorites from Sweden

The maximum diameter of chromite (FeCr2O4) grains within L chondrites reflects the petrographic type of the sample. On the basis of our measurements of nine recent L chondrites, L3 chromite D-mac = 34-50 mu m, L4 = 87-150 mu m, L5 = 76-158 mu m, and L6 = 253-638 mu m. This variation reflects the crystallization of the chromite grains during parent body thermal metamorphism.We use this calibration
