Chemical and mutational modification of histidines in violaxanthin de-epoxidase from Spinachcia oleracea.

The violaxanthin de-epoxidase (VDE) gene from spinach (Spinacia oleracea) was cloned, sequenced (GenBank AJ 250433), and expressed in Escherichia coli. The highest obtained conversion rate of violaxanthin was 86 nmol s-1 per litre of growth medium, corresponding to an amount of active enzyme of 0.4 mg l-1. Sequence comparison between VDE from different species were made and particular interest was

In-beam gamma-ray spectroscopy of Cd-103

Excited states of Cd-103 were studied in the reaction Ni-58(Cr-50,4pn)Cd-103. The NORDBALL array with neutron and charged particle detectors was employed for the detection of gamma rays and light evaporated particles. The level scheme of Cd-103 was significantly extended. A strong cascade of E2 transitions connecting negative parity states was found, Shell model calculations were performed and pos

Global Governance of AIDS : Partnerships with Civil Soviety

The global governance of AIDS is dependent for its success on the concerted efforts of actors from both local and global levels, thus challenging the current international organization based on state sovereignty. The study seeks to understand the processes behind the creation of partnerships among the many different nongovernmental organizations (NGOs) active in AIDS politics and the intergovernme

A program for computing autoionization properties

A program for computing atomic autoionization widths, decay rates and lifetimes is presented as a new part of the MCHF atomic structure package. The method used is based on the ''configuration interaction in the continuum'' theory by Fano, in which the continuum is computed independently of the discrete part and the width is given by the ''Golden Rule'' formula. The program allows for correlation

Travel Report from London

This report gives a summary of Anders Hansson's visit to Imperial College of Science, Technology andMedicine, London. An overview of the research together with a summary of impressions are given.

Multiple interactions in low x DIS and high energy pp collisions

The LDC formalism for DIS can describe HERA structure functions, and also agrees well with CTEQ and MRST gluon distributions. It is also suitable for hadronic collisions, and provides a strong connection between ep and pp reactions. Some preliminary results are presented.

Muscarinic receptors: their distribution and function in body systems, and the implications for treating overactive bladder

1 The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2 Muscarinic M-3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M-2 receptors may have a role

ATLAS Status and First Run Scenarios for B Physics

This article summarizes the status of the ATLAS detector and its commissioning as of autumn 2006, one year before the expected LHC start-up. The initial running scenarios and goals for B physics are presented for the foreseen pilot run with 900 GeV centre-of-mass energy in autumn 2007, as well as for the first physics run in 2008 at the nominal centre-of-mass energy of 14 TeV.

Focus on the tumor periphery in MRI evaluation of soft tissue sarcoma: infiltrative growth signifies poor prognosis

Purpose. Infiltrative microscopical peripheral growth of soft tissue sarcomas (STS) has been shown to be of prognostic importance and preoperative risk stratification could individualize neoadjuvant treatment. Patients and methods. We assessed peripheral tumour growth pattern on preoperative MRI from 78 STS. The findings were correlated to histopathology and to outcome. Results. The MRI-based peri

Contributions of Oi, Oe and Oa horizons to dissolved organic matter in forest floor leachates

The aim of this study was to identify the role of organic matter of the Oi, Oe and Oa layers for leaching of dissolved organic matter (DOM) from the O horizon in a podsolised forest soil in southern Sweden. Solid state C-13 cross polarization magic angle spinning (CPMAS) nuclear magnetic resonance (NMR) spectroscopy and C-14 measurements were used to analyse organic matter in solid material and wa

Airway epithelial repair: breathtakingly quick and multipotentially pathogenic

Epithelial shedding, even to the point of airway denudation, had already been described as a common and unifying feature of asthma by the latter half of the 19th century. However, the repair processes that specifically follow the shedding-like loss of epithelial cells have only recently been examined in vivo. This paper discusses the exceedingly fast epithelial restitution and the potential pathog

Predictors of improvement in quality of life of long-term mentally ill individuals receiving case management.

One hundred and thirteen long-term mentally ill clients receiving case management were investigated with regard to psychosocial and clinical predictors of changes in subjective quality of life during an 18-month follow-up. Better psychosocial functioning and fewer psychiatric symptoms at baseline predicted a greater improvement in quality of life. A larger decrease in symptom severity and a greate

Assisterad befruktning. Uppföljning av barn som nått skolåldern

Drygt 2 procent av alla svenska nyfödda barn har tillkommit med hjälp av in vitro-fertilisering, IVF, som är en medicinsk behandling för ofrivillig barnlöshet. Ägg och sperma förs samman utanför kroppen och det befruktade ägget planteras in i kvinnans livmoder. Alltsedan de första IVF-barnen föddes har frågor om såväl medicinska som sociala och psykologiska risker för barnet ställts av föräldrar,
