Antibacterial activity of 17 strains of lactobacilli was tested against 10 strains of H. pylori. The inhibition observed was related to the acid production and the low pH attained. No relationship between CagA phenotype of H, pylori strains and tolerance to lactic acid was observed. In mixed cultures, L. acidophilus CRL 639 showed an autolytic behavior after 24 h of culture. At this moment, H. py[

Falling birth rates within the European Union have given rise to a number of studies, trying to analyse and interpret why women (and men) choose not to have (many) children. One attempt in this direction is made by an ongoing EU-project, involving eight countries, including Sweden. Qualitative interviews focusing on couples' decisions to have- or not have - children have been carried out in each c

Benzene-fluorobenzene complexes are used as model systems to simulate the interactions of the SBB-HCAII protein-ligand complex. Using the second-order Moller-Plesset [MP2] and the coupled cluster singles and doubles including connected triple excitations models recently implemented with Cholesky decompositions we evaluate accurate interaction energies for several benzene-fluorobenzene van der Waal

Two industrial effluents, a pre-fermentation effluent and a post-fermentation effluent from a wheat starch production plant, were used as substrates for fuel ethanol production in anaerobic batch cultures using minimal nutritional amendment. The performances of three metabolically engineered xylose-utilizing Saccharomyces cerevisiae strains: TMB 3001 expressing XYL1, XYL2 and XKS1, redox metabolis

Background The Euglycemic Hyperinsulinemic Clamp (EHC) is the most widely used experimental procedure for the determination of insulin sensitivity, and in its usual form the patient is followed under insulinization for two hours. In the present study, sixteen subjects with BMI between 18.5 and 63.6 kg/m2 were studied by long-duration (five hours) EHC. Results From the results of this series and f

Abstract in French Cet article pose la question de savoir s’il existe une corrélation entre le niveau grammatical et le niveau lexical dans la production écrite d’apprenants de français langue étrangère. Nous avons appliqué un certain nombre d’indices quantitatifs et lexicaux et un indice grammatical à 40 textes en français, écrits par deux groupes d’apprenants adultes suédophones se situant à desThe paper addresses the question of whether there is a correlation between the grammatical developmental level and the lexical developmental level in the written production of learners of French as a foreign language. We have applied a number of quantitative and lexical measures and one grammatical measure to 40 texts in French written by two groups Swedish adults with different proficiency levels

In empirical research it is often of interest to include non-linear functions of the explanatory variables, such as squares or interactions, in the specification. A popular technique to estimate such models in the presence of common factors is the Common Correlated Effects (CCE) methodology. However, this approach assumes that the regressors are linear in the factors, which is not the case if vari

Ice core records are commonly used to infer information about past variability of CO2 fluxes. Because of processes involved in enclosing this air in ice, ice core records are a smoothed representation of the actual past atmospheric variations. As such, there is a limit to how much information ice core measurements can contain about flux variability on short timescales. With a numerical model of th

Prenatal exposure to the highly toxic and common pollutant cadmium has been associated with adverse effects on child health and development. However, the underlying biological mechanisms of cadmium toxicity remain partially unsolved. Epigenetic disruption due to early cadmium exposure has gained attention as a plausible mode of action, since epigenetic signatures respond to environmental stimuli a

The acquisition of preverbal liaison (e.g. ils arrivent /ilzaʀiv/) in second language (L2) French has rarely been explored in detail in previous studies on obligatory liaison. In this study, we conducted an elicited imitation test in order to study the influence of proficiency level, modality (spoken or written), and verb frequency on the use of preverbal liaison among 42 Swedish learners of L2 Fr

We employ Non-equilibrium Green's functions (NEGF) to describe the real-time dynamics of an adsorbate-surface model system exposed to ultrafast laser pulses. For a finite number of electronic orbitals, the system is solved exactly and within different levels of approximation. Specifically i) the full exact quantum mechanical solution for electron and nuclear degrees of freedom is used to benchmark

Profound changes in both marine and terrestrial biota during the end-Triassic mass extinction event and associated successive carbon cycle perturbations across the Triassic-Jurassic boundary (T-J, 201.3 Ma) have primarily been attributed to volcanic emissions from the Central Atlantic Magmatic Province and/or injection of methane. Here we present a new extended organic carbon isotope record from a
