O2-binding to heme: electronic structure and spectrum of oxyheme, studied by multiconfigurational methods

We have studied the ground state of a realistic model of oxyheme with multiconfigurational second-order perturbation theory (CASPT2). Our results show that the ground-state electronic structure is strongly multiconfigurational in character. Thus, the wavefunction is a mixture of many different configurations, of which the three most important ones are approximately 1FeII–1O2 (70%), (12%) and 3FeII

Impact of socioeconomic factors and antibiotic prescribing on penicillin- non-susceptible Streptococcus pneumoniae in the city of Malmö.

Carriage or infection with penicillin-non-susceptible Streptococcus pneumoniae (PNSP) has been associated with antibiotic prescribing, socioeconomic factors, and attendance at day-care centres (DCCs). In the present study, linear regression was used to estimate the relation between these risk factors and the incidence of PNSP cases (non-susceptible defined as MIC >= 0.5 mu g/ml for penicillin) in

Signals adapting the beta cells to changes in insulin sensitivity

Insulin sensitivity and secretion are related in a curvilinear inverse asymptotic function. However, the signaling factors mediating this relation are not known. In this study, we explored whether circulating glucose, lipids or two adipocyte-derived hormones, leptin and adiponectin, are related to the curvilinear function between insulin sensitivity and secretion in subjects with normal glucose to

The pattern of polymorphism in Arabidopsis thaliana

We resequenced 876 short fragments in a sample of 96 individuals of Arabidopsis thaliana that included stock center accessions as well as a hierarchical sample from natural populations. Although A. thaliana is a selfing weed, the pattern of polymorphism in general agrees with what is expected for a widely distributed, sexually reproducing species. Linkage disequilibrium decays rapidly, within 50 k

Naturgas Säkerhetsnivå Riskanalys

Denna rapport har tillkommit på uppdrag av NUTEK och avser att belysa riskerna med distribution och industriell användning av naturgas. Tidigare har en rapport avseende naturgasinstallationer i hemmen utgetts [1,2]. Rapporten inleds med en allmän diskussion om risker. Vidare tas frågan om lagstiftning, tillsyn, kontroll och utbildning för naturgasanvändning i olika lander upp. Dessutom har en retr

Prostate cancer - Prevalence-based healthcare costs

Objective: To calculate the total costs of in- and outpatient healthcare for patients with prostate cancer based on an episode-of-care approach. The cost analysis includes costs incurred during the first year of diagnosis, a longitudinal 3-year analysis and the incremental cost of prostate cancer during the first year of diagnosis. Material and Methods: Patients registered with prostate cancer bet

A qualitative study of conceptions and attitudes regarding maternal mortality among traditional birth attendants in rural Guatemala.

OBJECTIVE: To explore conceptions of obstetric emergency care among traditional birth attendants in rural Guatemala, elucidating social and cultural factors. STUDY: design Qualitative in-depth interview study. SETTING: Rural Guatemala. SAMPLE: Thirteen traditional birth attendants from 11 villages around San Miguel Ixtahuacán, Guatemala. METHOD: Interviews with semi-structured, thematic, open-ende

No relations between breast cancer risk and fatty acids of erythrocyte membranes in postmenopausal women of the Malmo Diet Cancer cohort (Sweden)

Objective: To examine the fatty acid composition of erythrocyte membranes, in relation to obesity indexes and breast cancer risk. Design: A nested case-control study. Setting: The Malmo Diet Cancer cohort, Sweden. Subjects: Among women 50 y or older at baseline (n=12803), incident breast cancer cases (n=237) were matched to controls (n=673) on age and screening date. Methods: A diet history method

A SANS contrast variation study of microemulsion droplet growth

An extensive small angle neutron scattering study is presented using contrast variation on the growth of nonionic microemulsion droplets as the temperature and thus spontaneous curvature is varied away from the emulsification failure boundary, EFB, toward zero spontaneous curvature. Two ternary systems are compared. They only differ by the chain length of the oil ( decane and hexadecane, respectiv

A mitogenomic study on the phylogenetic position of snakes

Phylogenetic relationships of squamates (lizards, amphisbaenians and snakes) have received considerable attention, although no consensus has been reached concerning some basal divergences. This paper focuses on the Serpentes (snakes), whose phylogenetic position within the Squamata remains uncertain despite a number of morphological and molecular studies. Some mitogenomic studies have suggested a

Search for excited electrons at HERA

A search for excited electron (e*) production is described in which the electroweak decays e* --> egamma, e* --> eZ and e* ---> nuW are considered. The data used correspond to an integrated luminosity of 120 pb(-1) taken in e(+/-)p collisions from 1994 to 2000 with the H1 detector at HERA at centre-of-mass energies of 300 and 318 GeV. No evidence for a signal is found. Mass dependent exclusion lim

PWLTool - a Matlab Toolbox for Piecewise Linear System

This manual describes a Matlab toolbox for computational analysis of piecewise linear systems. Key features of the toolbox are modeling, simulation, analysis, and optimal control for piecewise linear systems. The simulation routines detect sliding modes and simulate equivalent dynamics. The analysis and design are based on computation of piecewise quadratic Lyapunov functions. The computations are
