Ligands to the 2Fe iron-sulfur center in succinate dehydrogenase

Membrane-bound succinate oxidoreductases are flavoenzymes containing one each of a 2Fe, a 3Fe and a 4Fe iron-sulfur center. Amino acid sequence homologies indicate that all three centers are located in the Ip (B) subunit. From polypeptide and gene analysis of Bacillus subtillis succinate dehydrogenase-defective mutants combined with earlier EPR spectroscopic data, we show that four conserved cyste

Rare Variant Analysis of Human and Rodent Obesity Genes in Individuals with Severe Childhood Obesity

Obesity is a genetically heterogeneous disorder. Using targeted and whole-exome sequencing, we studied 32 human and 87 rodent obesity genes in 2,548 severely obese children and 1,117 controls. We identified 52 variants contributing to obesity in 2% of cases including multiple novel variants in GNAS, which were sometimes found with accelerated growth rather than short stature as described previousl

Modification of bovine heart succinate dehydrogenase with ethoxyformic anhydride and Rose bengal: Evidence for essential histidyl residues protectable by substrates

Purified and membrane-bound succinate dehydrogenase (SDH) from bovine heart mitochondria was inhibited by the histidine-modifying reagents ethoxyformic anhydride (EFA) and Rose Bengal in the presence of light. Succinate and competitive inhibitors protected against inhibition, and decreased the number of histidyl residues modified by EFA. The essential residue modified by EFA was not the essential

Effect of burner geometry on swirl stabilized methane/air flames : A joint LES/OH-PLIF/PIV study

Large eddy simulation (LES) using a transported PDF model and OH-PLIF/PIV experiments were carried out to investigate the quarl effects on the structures of swirl stabilized methane/air flames. Two different quarls were investigated, one straight cylindrical quarl and one diverging conical quarl. The experiments show that the flames are significantly different with the two quarls. With the straigh

Influence of prefiltration on membrane performance during isolation of lignin-carbohydrate complexes from spent sulfite liquor

In this study, we examined the isolation of lignin-carbohydrate complexes (LCCs) from sodium-based spent sulfite liquor, in conjunction with minimization of membrane fouling. We screened 3 polysulfone (PS) membranes with cutoffs of 100, 50, and 25 kDa, respectively. Flux and retention for the 100- and 50-kDa membranes had the same order of magnitude, indicating that these properties were determine

Research data is a product of (its) time

Research data are complicated things. The question of whether they are things at all is of course contentious. Yet, even if we leave this issue aside for now, there are continuous debates - some would say struggles - over who owns the data, how to handle and describe it, how to store and share more of it and why, in short, who has which interest in it. It is also unclear when it is appropriate to

Catch up growth and social capability in developing countries : a conceptual and measurement proposal

While the income per capita in the developing world since the turn of the Millennium has grown faster than that of the developed world, the question whether there is an ongoing process of catching up between countries remains. The notion of income convergence has provided many insights into the sources for long-run growth but has largely neglected the role of social capabilities in economic develo

Mechanisms and use of neural transplants for brain repair

Under appropriate conditions, neural tissues transplanted into the adult mammalian brain can survive, integrate, and function so as to influence the behavior of the host, opening the prospect of repairing neuronal damage, and alleviating symptoms associated with neuronal injury or neurodegenerative disease. Alternative mechanisms of action have been postulated: nonspecific effects of surgery; neur

Neighbourhood events and the visibilisation of everyday life : The cases of Turro (Milan) and Norra Fäladen (Lund)

While scholars agree on the reasons behind the current proliferation of urban, small-scale, pre-organised events, the implication of these events for public life is more controversial, and involves polarised debates between enthusiasts and critics. This paper develops an international comparison between one city district in Milan (Italy) and one in Lund (Sweden), in order to explore how the variet

Antibody Affinity Against 2009 A/H1N1 Influenza and Pandemrix Vaccine Nucleoproteins Differs Between Childhood Narcolepsy Patients and Controls

Increased narcolepsy incidence was observed in Sweden following the 2009 influenza vaccination with Pandemrix(®). A substitution of the 2009 nucleoprotein for the 1934 variant has been implicated in narcolepsy development. The aims were to determine (a) antibody levels toward wild-type A/H1N1-2009[A/California/04/2009(H1N1)] (NP-CA2009) and Pandemrix-[A/Puerto Rico/8/1934(H1N1)] (NP-PR1934) nucleo

Virtual entrepreneurs : Boundary spanning between the private and the public spheres in the entrepreneuring process

This article is located within the context of women entrepreneurs involved in the process of virtual enterprising. It examines the process of structure building as an embedding process from a constructivist perspective. The research aims to ask whether entrepreneurship is a boundless process embedded in family and firm at the same time and how they capitalized on structuring resources embedded in

Towards Active Learning Spaces and the Flipped Classroom Model

It has been acknowledged that the traditional didactic lecture does not always provide the ideal learning and teaching experience (Bligh, 1998). Over the last ten years, individuals and institutions have been exploring the pedagogical possibilities of providing more active and engaging alternatives. One model in particular has been influential in sparking change. The use of Active Learning Spaces

Perspectives in Business Informatics Research

This book constitutes the proceedings of the 16th International Conference on Perspectives in Business Informatics Research, BIR 2017, held in Copenhagen, Denmark, in August 2017.This year the BIR conference attracted 59 submissions from 23 countries. They were reviewed by 45 members of the Program Committee, and as a result, 17 full papers and 3 short papers were selected for presentation at the
