On generating digital elevation models from liDAR data – resolution versus accuracy and topographic wetness index indices in northern peatlands

Abstract Global change and GHG emission modelling are dependent on accurate wetness estimations for predictions of e.g. methane emissions. This study aims to quantify how the slope, drainage area and the TWI vary with the resolution of DEMs for a flat peatland area. Six DEMs with spatial resolutions from 0.5 to 90 m were interpolated with four different search radiuses. The relationship between ac

Cathepsin B Degrades Amyloid-beta in Mice Expressing Wild-type Human Amyloid Precursor Protein

Accumulation of amyloid-beta (A beta), believed to be a key trigger of Alzheimer disease (AD), could result from impaired clearance mechanisms. Previously, we showed that the cysteine protease cathepsin B (CatB) degrades A beta, most likely by C-terminal truncation, in mice expressing human amyloid precursor protein with familial AD-linked mutations (hAPP(FAD)). In addition, the A beta-degrading a

Comparing the performance of different stomatal conductance models using modelled and measured plant carbon isotope ratios (δ(13) C): implications for assessing physiological forcing

Accurate modelling of long-term changes in plant stomatal functioning is vital to global climate change studies because changes in evapotranspiration influence temperature via physiological forcing of the climate. Various stomatal models are included in land surface schemes, but their robustness over longer timescales is difficult to validate. We compare the performance of three stomatal models, v

A fully divergence-free method for generation of inhomogeneous and anisotropic turbulence with large spatial variation

A fully divergence-free method is proposed for generation of inhomogeneous/anisotropic turbulence with large spatial variation. The method is based on the method of Smirnov et al., which is known to violate the divergence-free constraint when spatial variation of turbulence is present. In the proposed method a vector potential field is introduced; by taking the vector curl of the potential field o

Short telomere length is associated with NOTCH1/SF3B1/TP53 aberrations and poor outcome in newly diagnosed chronic lymphocytic leukemia patients

Most previous studies on telomere length (TL) in chronic lymphocytic leukemia (CLL) are based on referral cohorts including a high proportion of aggressive cases. Here, the impact of TL was analyzed in a population-based cohort of newly diagnosed CLL (n=265) and in relation to other prognostic markers. Short telomeres were particularly associated with high-risk genetic markers, such as NOTCH1, SF3

Vanin-1 T26I polymorphism, hypertension and cardiovascular events in two large urban-based prospective studies in Swedes.

BACKGROUND AND AIMS: Vanin-1 (gene name VNN1) is an enzyme with pantetheinase activity generating the amino-thiol cysteamine which is implicated in the regulation of red-ox status through its effect on glutathione. We tested the hypothesis that the rs2294757 VNN1 T26I polymorphism could affect blood pressure (BP) levels, hypertension prevalence, and risk of incident cardiovascular events. METHODS

Physiotherapy as a promoter of sexual health.

Despite the holistic intention of physiotherapy, sexual health receives insufficient attention by physiotherapists. Sexual health is an important part of general health and well-being, which is often negatively affected by physical and psychological disorders. There are several reasons why sexual health should be addressed by physiotherapists, and this article aims to describe the role of the phys

Oh, it's you again: Memory interference from irrelevant emotional and neutral faces.

In two experiments, repeated runs of a continuous recognition task were employed to assess healthy participants' ability to handle interference from irrelevant emotional and neutral memories. Presumably, such interference can be due to salience from either emotional or mnemonic processing. In both experiments, participants made more false alarms to emotional faces that were familiar from preceding

Heparin does not improve graft function in uncontrolled non-heart-beating lung donation: an experimental study in pigs

OBJECTIVES: Non-heart-beating donation (NHBD) has the potential to increase the number of patients treated with lung transplantation. Our study investigated, in a simulated clinical situation in the uncontrolled NHBD setting, whether or not heparin administration after death affects the donor lung function. METHODS: Twelve Swedish domestic pigs underwent ventricular fibrillation and were left unto

Internal water and microsecond dynamics in myoglobin.

Myoglobin (Mb) binds diatomic ligands, like O2, CO, and NO, in a cavity that is only transiently accessible. Crystallography and molecular simulations show that the ligands can migrate through an extensive network of transiently connected cavities but disagree on the locations and occupancy of internal hydration sites. Here, we use water (2)H and (17)O magnetic relaxation dispersion (MRD) to chara

100% complete assignment of non-labile H-1, C-13, and N-15 signals for calcium-loaded calbindin D-9k P43G

Here we present the 100% complete assignment chemical shift of non-labile H-1, N-15 and C-13 nuclei of Calbindin D-9k P43G. The assignment includes all non-exchangeable side chain nuclei, including ones that are rarely reported, such as LysN zeta as well as the termini. NMR experiments required to achieve truly complete assignments are discussed. To the best of our knowledge our assignments for Ca

The Biobanking Analysis Resource Catalogue (BARCdb): a new research tool for the analysis of biobank samples.

We report the development of a new database of technology services and products for analysis of biobank samples in biomedical research. BARCdb, the Biobanking Analysis Resource Catalogue (http://www.barcdb.org), is a freely available web resource, listing expertise and molecular resource capabilities of research centres and biotechnology companies. The database is designed for researchers who requ

Indication criteria for cataract extraction and gender differences in waiting time.

Purpose: The purpose of this study was to investigate national indication criteria tool for cataract extraction (NIKE), a clinical tool for establishing levels of indications for cataract surgery, in relation to gender differences in waiting times for cataract extraction (CE). Methods: Data were collected by The Swedish National Cataract Register (NCR). Eye clinics report to NCR voluntarily and on

Alternatively folded proteins with unexpected beneficial functions

HAMLET (human alpha-lactalbumin made lethal to tumour cells) and its related partially unfolded protein-fatty acid complexes are novel biomolecular nanoparticles that possess relatively selective cytotoxic activities towards tumour cells. One of the key characteristics is the requirement for the protein to be partially unfolded, hence endowing native proteins with additional functions in the alter

Correlation between Stated and Measured Concentrations of Acrylate and Methacrylate Allergens in Patch-Test Preparations

Background: Contact allergy to acrylates and methacrylates is not uncommon. The allergy is confirmed by patch-testing patients with commercial patch-test preparations. Objective: To investigate acrylate and methacrylate allergens used for patch testing in nine different dermatology departments from Europe, America, Asia, and Australia. Methods: The acrylate and methacrylate (methyl methacrylate, 2

Fruit and vegetable intake and cause-specific mortality in the EPIC study

Consumption of fruits and vegetables is associated with a lower overall mortality. The aim of this study was to identify causes of death through which this association is established. More than 450,000 participants from the European Prospective Investigation into Cancer and Nutrition study were included, of which 25,682 were reported deceased after 13 years of follow-up.
