Polyethyleneimine (PEI) is an organic polycation used extensively as a gene- and DNA vaccine delivery reagent. Although the DNA targeting activity of PEI is well documented, its immune activating activity is not. We recently reported that PEI has robust mucosal adjuvanticity when administered intranasally with glycoprotein antigens. Here we show that PEI has strong immune activating activity after

We study the chemical abundances of the strontium filament found in the ejecta of eta Carinae. In particular, we derive the abundances of iron-peak elements from the spectra of their singly ionized ions present in the optical/infrared (IR) spectra. In this paper we analyse the spectrum of Mn II using a new non-local thermodynamic equilibrium (non-LTE) model for this system. In constructing this mo

Parity forbidden radiative transitions from metastable levels are observed in spectra of low-density astrophysical plasmas. These lines are used as probes of the physical conditions, made possible due to the long lifetime of their upper level. In a joint effort, the FERRUM project aims to obtain new and accurate atomic data for the iron-group elements, and part of this project concerns forbidden l

In this study we establish the use of optical non-contact profilometry combined with low vacuum scanning electron microscopy (LV SEM) for the investigation of lipid surfaces. We illustrate, by using profilometry, a methodology for investigation of chocolate surface topology as a function of time, in the same area of interest. Both qualitative and quantitative data analysis has been performed for p

Popular Abstract in Swedish I sökandet efter den rådande fostrings- och disciplineringsdiskursen i svensk skola åren 1947-1956 har Michel Foucaults diskursanalys utgjort en central utgångspunkt i denna avhandling. Jag har inledningsvis redogjort för modernitetens genombrott i Sverige och kort belyst befolkning och utbildning vid mitten av 1900-talet. Skolan som disciplineringsinstitution har beskThe purpose of this monograph is to discern what constituted the dominant fostering and discipline discourse in Swedish compulsory schools during the period 1947-1956. For this purpose Michel Foucault's discourse analysis has played a central role in this thesis. As a starting point, an account of the emergence of modernity in Sweden is given, as well as a brief presentation of the Swedish populat

This study considers the spread, character and development of the Swedish Enlightenment from the early Age of Liberty to the late Karl lohan period. This is done in six case studies three of them biographical and three of them of a more general character partly concerned with the history of concepts; all six case studies touch on the writers' world in the period. Chapter 1, "Dawn", discusses, aft

Objectives We tested the hypothesis that serum total testosterone and sex hormone-binding globulin (SHBG) levels predict cardiovascular (CV) events in community-dwelling elderly men. Background Low serum testosterone is associated with increased adiposity, an adverse metabolic risk profile, and atherosclerosis. However, few prospective studies have demonstrated a protective link between endogenous

Targeted proteomics allows researchers to study proteins of interest without being drowned in data from other, less interesting proteins or from redundant or uninformative peptides. While the technique is mostly used for smaller, focused studies, there are several reasons to conduct larger targeted experiments. Automated, highly robust software becomes more important in such experiments. In additi

The paper explores the implementation process of an innovation measuring system prototype to support a heavy machinery multinational company to secure their innovative capability. In general, companies recognize the importance of becoming innovative to become, or remain, competitive on a global market. The case company decided to pilot a metric system that corresponds to the crucial factors to sec

The following report provides an overview of the discussions and outcome of the EuPA General Council meeting that took place in Estoril 20-21 October 2010. During the annual meeting future policy and action plans in a variety of areas are decided. Several important points were decided upon during this meeting including the expansion of the EuPA Executive Committee by introducing a new EuPA committ

We present detailed chemical element abundance ratios of 17 elements with eight <= Z <= 60 in three metal-poor stars in the Ursa Minor dwarf spheroidal galaxy, which we combine with extant data from the literature to assess the predictions of a novel suite of galaxy chemical evolution models. The spectroscopic data were obtained with the Keck/High-Resolution Echelle Spectrograph instrument and rev

The goal of this paper is to determine concentrations of seven selected perfluoroalkylated substances (PFASs): perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA) in the blood serum of men and women of reproductiv

Chemokine signaling has been implicated in directing colonization of the fetal thymus by hematopoietic precursors. However, the patterns of expression of the chemokine receptors responsible for directing thymic colonization by the earliest thymic migrants remain unknown. We have identified heterogeneity within the earliest thymus seeding cells based on chemokine receptor expression. By analyzing t

Early gastric cancer (EGC) is defined as a carcinoma limited to the mucosa or mucosa and submucosa, irrespective of whether metastasis to lymph nodes has occurred. EGC presents a much more favorable prognosis than advanced gastric carcinoma (AGC), with a 5-year survival rate between 88% and 96% for EGC versus 45% to 50% for AGC. Moreover, some gastric cancers appear as a more or less extended EGC

We present a generic approach for quantitative differential proteomics that reduces data complexity in proteome analysis by automated selection of peptides for MS/MS analysis according to their isotope-labeling ratio. Isotopic reagents were developed that give products which fragment easily to generate a unique pair of signature ions. Using the ion-pair ratio, we show that it is possible to select
