Conflicting demands on wetland ecosystem services: nutrient retention, biodiversity or both?

1. Wetland ecosystems may, besides having considerable economical value, increase landscape biodiversity and function as traps for nutrients from land to freshwater- and marine systems. As a result of these features, wetlands are nowadays often protected and restored, and many countries have even initiated wetland construction programmes. 2. In the present study, we aim at increasing the knowledge

Monitoring of glucose and glutamate using enzyme microstructures and scanning electrochemical microscopy.

Glucose oxidase and glutamate oxidase lines, with typical width of 100 microm, were patterned on gold surfaces using a micro-dispensing system, by shooting 100 pl droplets of the corresponding enzyme solutions. The probe of a scanning electrochemical microscope (SECM) was then carefully positioned in the close proximity of the enzyme microstructure and poised to +600 mV vs. Ag/AgCl, KCl 0.1 M. The

Enteral crude red kidney bean (Phaseolus vulgaris) lectin--phytohemagglutinin--induces maturational changes in the enterocyte membrane proteins of suckling rats.

This study aimed to investigate the effect of enterally administered crude red kidney bean (Phaseolus vulgaris) lectin, PHA, on the expression of brush-border membrane vesicle (BBMV) proteins, in particular Na+/H+ exchangers (NHEs), in the small intestine of suckling rats. Gavage of PHA to 14-day-old rats for 3 days resulted in altered protein/glycoprotein patterns as analyzed by SDS-PAGE. Immunob

Magnetic resonance imaging and histopathology in dementia, clinically of frontotemporal type

The magnetic resonance imaging (MRI) and computed tomography findings in 28 patients with the clinical diagnosis of frontotemporal dementia (FTD) were compared with the findings in a control group of 76 individuals without dementia or stroke. A pattern of frontal and temporal atrophy with predominantly frontal white matter changes was found in the FTD patients, and this was significantly different

Analytic derivatives for the Cholesky representation of the two-electron integrals.

We propose a formalism for calculating analytic derivatives of the electronic energy with respect to nuclear coordinates using Cholesky decomposition of the two-electron integrals. The formalism is derived by exploiting the equivalence of Cholesky decomposition and density fitting when a suitable auxiliary basis set is used for expanding atomic orbital product densities in the latter. An implement

Vaccination against atherosclerosis? Induction of atheroprotective immunity

Atherosclerosis involves the formation of inflammatory arterial lesions and is one of the most common causes of death globally. It has been evident for more than 20 years that adaptive immunity regulates the magnitude of the atherogenic proinflammatory response. T cells may also influence the stability of the atherosclerotic lesion and thus the propensity for thrombus formation and the clinical ou

Relatives' view on collaboration with nurses in acute wards: Development and testing of a new measure

Background: Collaboration between relatives and nurses in acute care settings is sparsely investigated, and that mostly from nurses' point of view. Feasible and valid instruments are needed for assessing collaboration, its prerequisites and outcome. Objectives: To develop and test an instrument to assess, from the relatives' perspective, collaboration between relatives of frail elderly patients an

Low glycaemic index (GI) foods improve glucose control in children with type I diabetes.

Aim: Does metabolic control improve in children with insulin dependent diabetes mellitus (IDDM), when modifying the quality of carbohydrates by introducing low glycaemic index (GI) foods? Methods: The inclusion criteria for the study was children with diabetes mellitus type 1, age from 7 to 11 years old, they should have a moderate glucose control with HbA1c between 7,5 to 8,5 and no allergy to ce

Psoriasin, one of several new proteins identified in nasal lavage fluid from allergic and non-allergic individuals using 2-dimensional gel electrophoresis and mass spectrometry

Background: Extravasation and luminal entry of plasma occurs continuously in the nose. This process is markedly facilitated in patients with symptomatic allergic rhinitis, resulting in an increased secretion of proteins. Identification of these proteins is an important step in the understanding of the pathological mechanisms in allergic diseases. DNA microarrays have recently made it possible to c

Development and characterisation of a recombinant Saccharomyces cerevisiae mutant strain with enhanced xylose fermentation properties

The purpose of this study was to help lay the foundation for further development of xylose-fermenting Saccharomyces cerevisiae yeast strains through an approach that combined metabolic engineering and random mutagenesis in a recombinant haploid strain that overexpressed only two genes of the xylose pathway. Previously, S. cerevisiae strains, overexpressing heterologous genes encoding xylose reduct

Cue words and the topic structure of spoken discourse: The case of Swedish men 'but'

The Swedish cue word men ‘but’ can mark the boundary between both different topic units as well as topic-internal units in spontaneous speech. The goal of this study is to see if these two functions of men can be distinguished on the basis of their local prosodic correlates and co-occurring lexical items. Men-tokens in spontaneous narrations were labelled as to their function, first using text-onl

Hematopoietic Stem Cell Expansion Precedes the Generation of Committed Myeloid Leukemia-initiating Cells in C/EBP alpha Mutant AML

We here use knockin mutagenesis in the mouse to model the spectrum of acquired CEBPA mutations in human acute myeloid leukemia. We find that C-terminal C/EBP alpha mutations increase the proliferation of long-term hematopoietic stem cells (LT-HSCs) in a cell-intrinsic manner and override normal HSC homeostasis, leading to expansion of premalignant HSCs. However, such mutations impair myeloid progr

Observations on limnological conditions associated with a fish kill of Oreochromis niloticus in Lake Chivero following collapse of an algal bloom

Possible causes of deaths of Oreochromis niloticus in Lake Chivero were examined in relation to changes in limnological conditions monitored over a 25-month period. The fish deaths coincided with the collapse of an algal bloom that had developed and builtup in the lake for 8 months. Chlorophyll a and dissolved oxygen increased to average concentrations of 42.4 mu g l(-1) and 10.9 mg l(-1) respecti

Characteristics of the social environment of small group homes for individuals with severe mental illness

As part of research into small group homes run by local authorities for those with severe mental illness the characteristics of the social environment was investigated. The ideal and real versions of the Community Oriented Program Environmental Scale (COPES) were administered to residents and staff of small group homes in a county in southern Sweden. Both these groups were also interviewed on thei

Consideration of pitfalls in and omissions from the current ECG standards for diagnosis of myocardial ischemia/infarction in patients who have acute coronary syndromes

The ECG is the key clinical test available for the emergency determination of which patients who presenting with acute coronary syndromes indeed have acute myocardial ischemia/infarction. Because typically the etiology is thrombosis, the correct clinical decision regarding reperfusion therapy is crucial. This review follows the efforts of an AHA working group to develop new standards for clinical

Physicochemical and drug delivery aspects of lipid-based liquid crystalline nanoparticles: A case study of intravenously administered propofol

Liquid crystalline nanoparticles (LCNP) formed through lipid self-assembly have a range of attractive properties as in vivo drug delivery carriers. In particular they offer: a wide solubilization spectrum, and consequently high drug payloads; effective encapsulation; stabilization and protection of sensitive drug substances. Here we present basic physicochemical features of non-lamellar LCNP syste
