A gas chromatographic method was developed to quantify the phytotoxin prehelminthosporol, which is a sesquiterpene metabolite of the plant pathogen Bipolaris sorokiniana. The toxin was extracted from mycelium or culture filtrates, pre-cleaned using solid phase extraction, and analyzed by gas chromatography as a trimethylsilyl-derivative. The detection limit of the method was 5 ng mul(-)1 (signal t
Investigations of chemical bonding and electronic structure features for polycrystalline (porphyrinato)nickel (II) (NiP, the simplest Ni porphyrin), (5,10,15,20-tetraphenylporphyrinato)nickel (II) (NiTPP) and (2-aza-21-carba-5,10,15,20-tetraphenylporphyrinato)nickel (II) (N-confused NiTPP, NiNCTPP) have been performed by means of high-resolution soft x-ray absorption and x-ray photoemission spectr
Within the European Prospective Investigation into Cancer and Nutrition (EPIC), the authors examined the association of ethanol intake at recruitment (1,119 cases) and mean lifelong ethanol intake (887 cases) with lung cancer. Information on baseline and past alcohol consumption, lifetime tobacco smoking, diet, and the anthropometric characteristics of 478,590 participants was collected between 19
The relationship between on the one hand personality traits and, on the other hand, neuropsychological test performance, self-rated distress symptoms, psychosocial work exposure, and social interaction patterns, was studied in a group of healthy women (N= 101). All subjects completed the Karolinska Scales of Personality inventory (KSP) and the majority of the subjects (n = 88) completed the State
The purpose of the present study was threefold: (a) to replicate the finding by MacLeod and Rutherford (1992) that low trait-anxious individuals, in contrast to high trait-anxious individuals, show a selective attention away from subliminally presented threat words at elevated levels of stress; (b) to test the hypothesis that this effect is due to individuals with repressive coping-style rather th
Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H -> gamma gamma, H -> ZZ* -> 4l and H -> WW* -> l nu l nu. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of root s = 7 TeV and root s = 8 TeV, corre
Final results from the DELPHI Collaboration on the lifetime of B+ and B-0 mesons and the mean b-hadron lifetime, are presented using the data collected at the Z(0) peak in 1994 and 1995. Elaborate, inclusive, secondary vertexing methods have been employed to ensure a b-hadron reconstruction with good efficiency. To separate samples of B+ and B-0 mesons, high performance neural network techniques a
Long-term eddy covariance measurements of energy and water fluxes and associated climatic parameters were carried out above a Scots pine (Pinus sylvestris) forest in the middle taiga zone of Central Siberia. Data from June 1998 through October 2000 are presented. With the exception of winter 1998/1999, data collection over this period were more or less continuous. A distinct seasonality in surface
Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relative
Popular Abstract in Swedish Denna avhandling presenterar data från två olika geografiska områden, Dronning Maud land, Antarktis, och den Skandinaviska fjällkedjan som befinner sig på den Baltiska kontinentalplattan. Dessutom presenteras en jämförande studie mellan två metoder att datera bergarter. Berggrunden i Dronning Maud Land domineras dels av migmatiserade bergarter, dels av post-tektoniska This thesis presents data from two areas, Dronning Maud Land, Antarctica, and the Scandinavian Caledonides, Baltica. In addition, a comparative geochronological study is presented. The bedrock of Dronning Maud Land (DML) is dominated by migmatitic gneisses and post-tectonic intrusions. A migmatitic gneiss at Jutulsessen nunataks, Gjelsvikfjella, has a protolith age of 1163 ± 6 Ma and a migmatisati
The aim of this study is to try and explain the relationship between violence and the changes taking place in social spaces. Violence, in all its dimensions, has taken a central place in Latin American social life and has become an almost totally private issue. This implies a series of spatial and social transformations in the cities. The new effects of violence influence social and ethnic segrega
Macrolides have been used for decades as an important chemotherapeutic agent in the treatment of infectious diseases. In the last 10 years there has also been increasing interest in the interaction between macrolide antibiotics and the immune system. The aim of this review is to focus on the anti-inflammatory action of erythromycin and its derivatives in the treatment of chronic sinusitis and nasa
PURPOSE. To compare intersubject variability and normal limits of threshold values between the new Swedish interactive test algorithm short wavelength automated perimetry (SITA SWAP) and the older Full Threshold SWAP programs (Carl Zeiss Meditec, Dublin, CA). METHODS. Normal reduction of differential tight sensitivity with age, age-corrected thresholds, intersubject variability, and normal limits
Objective. When treatments with the potential to change the natural history of a disease are introduced, their longer-term effect on costs and quality of life (utility) has to be estimated using economic models. However, to remain useful tools, models must be updated when new information becomes available. Our earlier models in rheumatoid arthritis (RA) have been based on functional status, but it
Background: Pancreatic acinar-like metaplasia has previously been described in the gastric mucosa and in the distal part of the oesophagus. The resemblance to pancreatic acinar cells prompted us to study the possible occurrence of secretory pancreatic proteins in these cells. Methods: Seven specimens obtained from the distal oesophagus at gastroscopy where routine microscopy showed pancreatic acin
