Coadsorption of Cu(II) and glyphosate at the water-goethite (alpha-FeOOH) interface: molecular structures from FTIR and EXAFS measurements

The coadsorption of Cu(II) and glyphosate (N-(phosphonomethyl)glycine, abbreviated to PMG) at the water-goethite interface was studied by means of batch adsorption experiments, attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, and extended X-ray absorption fine structure (EXAFS) spectroscopy. The system was investigated over the pH range 3-9 and at total concentratio

Nontypeable Haemophilus influenzae strains with the capsule-associated insertion element IS1016 may mimic encapsulated strains

With the elimination of Haemophilus influenzae type b through vaccination, it has been suggested that other types of H. influenzae strains might acquire virulence traits and emerge as important pathogens. The gene sequence IS1016 has been associated with an increased capacity to cause severe infections. It is usually present in encapsulated strains but is sometimes harbored by nontypeable H. influ

Studies of intermolecular vibrations in hydrogen-bonded molecular complexes for the gas phase using a synchrotron radiation source

An electron storage ring acts as an approximate point source in the far-infrared spectral region with a much greater intensity than provided by conventional black body radiators. Far-infrared synchrotron radiation is therefore suitable for high-resolution spectroscopic measurements of low-frequency vibrations for metastable molecules such as the intermolecular vibrational modes of hydrogen-bonded

Flight and oviposition behavior of Ephestia cautella and Plodia interpunctella in response to odors of different chocolate products

The present study is included in a project with the aim to develop attractants from food odors for trapping female moths. Males and mated, but not unmated, females of Ephestia cautella and Plodia interpunctella were attracted by odors of three different chocolate products in flight tunnel experiments. Chocolate containing nut or rum elicited upwind flight and landing responses. Extracts of the cho

Smoking and the risk of gastric cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Smoking has recently been recognised as causally associated with the development of gastric cancer (GC). However, evidence on the effect by sex, duration and intensity of smoking, anatomic subsite and cessation of smoking is limited. Our objective was to assess the relation between tobacco use and GC incidence in the European Prospective Investigation into Cancer and Nutrition (EPIC). We studied d

Studies of chronic ITP in children and adolescents.

This paper presents an ongoing study of children with chronic ITP in Sweden that addresses four specific questions: is there a subgroup of children with chronic ITP that have impaired platelet function? Do children in this subgroup have antibodies directed against surface glycoproteins that are crucial for platelet function? Can desmopressin improve the impaired platelet function in this subgroup?

Diplomatic Signalling in the Television Age

To what extent does television interfere with and complicate diplomatic signaling via other channels? Conversely, to what extent can world leaders and diplomats use television to their advantage? Exploring these questions, this article focuses on the combination of communication speed and excitable public opinion, on the one hand, and the metaphorical and symbolic aspects of the medium, on the oth

Precipitation by polycation as capture step in purification of plasmid DNA from a clarified lysate

The demand for highly purified plasmids in gene therapy and plasmid-based vaccines requires large-scale production of pharmaceutical-grade plasmid. Large-scale purification of plasmid DNA from bacterial cell culture normally includes one or several chromatographic steps. Prechromatographic steps include precipitation with solvents, salts, and polymers combined with enzymatic degradation of nucleic

An alkaline active xylanase: Insights into mechanisms of high pH catalytic adaptation.

The alkaliphilic bacterium, Bacillus halodurans S7, produces an alkaline active xylanase (EC 3.2.1.8), which differs from many other xylanases in being operationally stable under alkaline conditions as well as at elevated temperature. Compared to non-alkaline active xylanases, this enzyme has a high percent composition of acidic amino acids which results in high ratio of negatively to positively c

Pancreatic dysfunction in acute pancreatitis

In the normal setting, the release of digestive substances and hormones from the pancreas is closely regulated. However, a variety of diseases, such as acute pancreatitis (AP), may disturb this balance. A limited number of studies on exocrine function in the acute phase of pancreatitis have been performed, most of them in animals. In the convalescent phase of AP, a substantial number of patients w

Instantaneous end moraine and sediment wedge formation during the 1890 glacier surge of Brúarjökull, Iceland

Contemporary understanding of the behaviour of surging glaciers and ice streams is hampered by the lack of data on landsystem evolution and sedimentary environments. This study concerns the ice-marginal environment of the surge-type Brúarjökull in Iceland. The sediment distribution in the glacier forefield as well as the morphology, sedimentology and tectonic architecture of the 1890 end moraine i

Development of reagents for differential protein quantitation by subtractive parent (precursor) ion scanning

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

ADL dependence in the elderly population living in the community: the influence of functional limitations and physical environmental demand

Empirical research elucidating the relationships between aspects of functional competence and environmental factors is lacking. This study aimed to analyse how functional limitations in the individual and housing accessibility problems influence ADL dependence in the elderly population, and to test Lawton's docility hypothesis. Data were collected from 133 Swedish subjects aged 75–84, who were liv

Monocyte and Neutrophil Chemotactic Activity at the Site of Interstitial Inflammation in Patients on High-Flux Hemodialysis or Hemodiafiltration

Background/Aims: We have observed a difference between patients on low-flux hemodialysis (HD) or peritoneal dialysis and patients on hemodiafiltration (HDF) or high-flux HD in the capacity of transmigrated leukocytes to mobilize CD11b in response to inflammatory stimuli compared with healthy subjects. This could be due to different interstitial chemokine concentrations. Methods: We measured concen
