Nitrogen is the only macronutrient that is commonly available to plants in both oxidized and reduced forms, mainly nitrate and ammonium. The physiological and molecular effects of nitrate supply have been well studied, but comparatively little is known about ammonium nutrition and its differential effects on cell function and gene expression. We have used a physiologically realistic hydroponic gro
Background High plasma HDL cholesterol is associated with reduced risk of myocardial infarction, but whether this association is causal is unclear. Exploiting the fact that genotypes are randomly assigned at meiosis, are independent of non-genetic confounding, and are unmodified by disease processes, mendelian randomisation can be used to test the hypothesis that the association of a plasma biomar
Under the current accounting systems, emissions produced when biomass is burnt for energy are accounted as zero, resulting in what is referred to as the 'carbon neutrality' assumption. However, if current harvest levels are increased to produce more bioenergy, carbon that would have been stored in the biosphere might be instead released in the atmosphere. This study utilizes a comparative approach
The mineralogy, petrology, and fluid inclusion chemistry of two charnockite patches within a distance of 4-5 km of the Varberg magmatic charnockite intrusion, SW Sweden, are investigated and described utilizing SEM, EMPA, and fluid inclusion microthermometry. Garnet-clinopyroxene (890-930 degrees C), garnet-amphibole (600-800 degrees C), and garnet-biotite (670-860 degrees C) Fe-Mg exchange thermo
The bisphenols AF (BPAF) and S (BPS) are structural analogs of the endocrine disruptor bisphenol A (BPA), and are used in common products as a replacement for BPA. To elucidate genome-wide gene expression responses, estrogen-dependent osteosarcoma cells were cultured with 10nM BPA, BPAF, or BPS, for 8h and 3months. Genome-wide gene expression was analyzed using the Illumina Expression BeadChip. Th
BACKGROUND: Most men with elevated levels of prostate-specific antigen (PSA) do not have prostate cancer, leading to a large number of unnecessary biopsies. A statistical model based on a panel of four kallikreins has been shown to predict the outcome of a first prostate biopsy. In this study, we apply the model to an independent data set of men with previous negative biopsy but persistently eleva
Barley malt, a product of controlled germination, has been shown to produce high levels of butyric acid in the cecum and portal serum of rats and may therefore have anti-inflammatory effects. The aim of the study was to investigate how four barley malts, caramelized and colored malts, 50-malt and 350-malt, differing in functional characteristics concerning beta-glucan content and color, affect sho
A complete system for on-line sampling, sample handling and analysis of fermentation processes has been set up. The system is designed such that a sample is taken from the fermentor, the metabolism of microbial cells is instantaneously arrested, the cells are lysed in order to release intracellular compounds and in a subsequent binding assay the content of target molecules is monitored. The system
The aim of the study was to examine relationships between psychosocial family- and school environment and personality as assessed by the Junior Eysenck Personality Questionnaire (EPQ-J) and possible personality interactional effects. The study was based on 244 Swedish girls and boys, 10-19 years old, who filled in the Family- and School Psychosocial Environment (FSPE) questionnaire and the EPQ-J.
Summary. Nonacog alfa, a recombinant factor IX (FIX) used for the treatment of haemophilia B, was approved in Europe in 1998. In accordance with European Medicines Agency requirements, a registry study was conducted from 2002 to 2009. A reformulated iso-osmotic version was approved for European use in 2007. This study was conducted to evaluate the safety of nonacog alfa in a usual care setting, an
A mechanism for three-photon double ionization of atoms by extreme-ultraviolet free-electron laser pulses is revealed, where in a sequential process the second ionization step, proceeding via resonant two-photon ionization of ions, is strongly enhanced by the excitation of ionic autoionizing states. In contrast to the conventional model, the mechanism explains the observed relative intensities of
The psychosocial work environment is an important factor in psychiatric in-patient care, and knowing more of its correlates might open up new paths for future workplace interventions. Thus, the aims of the present study were to investigate perceptions of the psychosocial work environment among nursing staff in psychiatric in-patient care and how individual characteristicsMastery, Moral Sensitivity
Abstract Mycobacterium marinum infection of the hand is rare. We report the case of a 39-year-old man with M marinum infection that resulted in a chronic soft tissue infection, extensor tendon synovitis, and arthritis of the metacarpophalangeal (MCP) joints. The cause was probably tropical freshwater fishes.
Collaboration by two grounded theory researchers, who each had developed a learning continuum instrument, led to the emergence of a new tool for assessment of learning powered mobility use. We undertook a rigorous process of comparative reanalysis that included merging, modifying, and expanding our previous research findings. A new instrument together with its facilitating strategies emerged in th
The understanding of multiple bubbles condensation is of significant importance in developing continuum models for the large-scale subcooled flow boiling. The computational fluid dynamics (CFD) modeling for multiple bubbles condensation is developed with the volume of fluid (VOF) method in this work. An explicit transient simulation is performed to solve the governing equations including the sourc
Immunoglobulin A (IgA) nephropathy is a chronic glomerulonephritis with excessive glomerular deposition of IgA1, C3 and C5b-9, which may lead to renal failure.
