Suppression of the external mitochondrial NADPH dehydrogenase, NDB1, in Arabidopsis thaliana affects central metabolism and vegetative growth.

Ca(2+)-dependent oxidation of cytosolic NADPH is mediated by NDB1, which is an external type II NADPH dehydrogenase in the plant mitochondrial electron transport chain. Using RNA interference, the NDB1 transcript was suppressed by 80% in Arabidopsis thaliana plants, and external Ca(2+)-dependent NADPH dehydrogenase activity became undetectable in isolated mitochondria. This was linked to a decreas

Structured Diagnostic and Treatment Approach Versus the Usual Primary Care Approach in Patients With Gastroesophageal Reflux Disease: A Cluster-randomized Multicenter Study.

GOALS:: To compare the clinical outcomes of gastroesophageal reflux disease (GERD) patients treated with an implemented new structured pathway (NSP) or according to existing local clinical practices [old clinical pathway (OCP)]. BACKGROUND:: GERD is a major challenge at the primary care level. STUDY:: Primary care centers (n=24) were cluster randomized to handle patients suffering from symptoms su

Social determinants of the sick building syndrome: exploring the interrelated effects of social position and psychosocial situation.

This paper examines the importance of various social factors for the prevalence of "sick building syndrome" (SBS) in residential buildings. A survey has been conducted in Malmö, Sweden, resulting in 1131 randomly selected residents participating in the study (response rate 57 %). Two clusters of social factors were examined: the socio-structural position of the individual and psychosocial aspects

Disappearing liver metastases from colorectal cancer: impact of modern imaging modalities.

Chemotherapy is often used before a resection for colorectal liver metastases. After chemotherapy, metastases may disappear on cross-sectional imaging but residual metastatic disease may still exist. The aim of this retrospective study was to investigate the impact of new advancements in imaging technology such as magnetic resonance imaging (MRI) with liver-specific contrast (Gd-EOB-DTPA) and cont

Quantifying the Semantic Representations of Adolescents' Memories of Positive and Negative Life Events

We quantified the semantic content in adolescents’ descriptions of positive and negative life events and studied how these descriptions are related to the assessment Subjective Well-Being (SWB) at two points in time. The semantic content of the descriptions was quantified by Latent Semantic Analysis (LSA). LSA is a computational method based on algorithms stemming from computational linguistics, w

Healthcare matching - Conditions for developing a New Service System in Healthcare’

Purpose The purpose is to outline the conditions for a new service system in healthcare, which will be able to match the available capacity in and between healthcare units in order to match the need of care for the patients. Methodology By drawing on statements from patients, experiences from similar services (a literature review), empirical research into the effects of the reforms on free choice

Toluene diisocyanate: Induction of the autotaxin-lysophosphatidic acid axis and its association with airways symptoms.

Diisocyanates are industrial chemicals which have a wide range of applications in developed and developing countries. They are notorious lung toxicants and respiratory sensitizers. However, the mechanisms behind their adverse effects are not adequately characterized. Autotaxin (ATX) is an enzyme producing lysophosphatidic acid (LPA), and the ATX-LPA axis has been implicated in lung related inflamm

Forest water use and water use efficiency at elevated CO2: a model-data intercomparison at two contrasting temperate forest FACE sites

Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed

Note on off-shell relations in nonlinear sigma model

In this note, we investigate relations between tree-level off-shell currents in nonlinear sigma model. Under Cayley parametrization, all odd-point currents vanish. We propose and prove a generalized U(1) identity for even-point currents. The off-shell U(1) identity given in [1] is a special case of the generalized identity studied in this note. The on-shell limit of this identity is equivalent wit

Gene fusion detection in formalin-fixed paraffin-embedded benign fibrous histiocytomas using fluorescence in situ hybridization and RNA sequencing.

Benign fibrous histiocytomas (FH) can be subdivided into several morphological and clinical subgroups. Recently, gene fusions involving either one of two protein kinase C genes (PRKCB and PRKCD) or the ALK gene were described in FH. We here wanted to evaluate the frequency of PRKCB and PRKCD gene fusions in FH. Using interphase fluorescence in situ hybridization on sections from formalin-fixed par

Cigarette smoking and risk of histological subtypes of epithelial ovarian cancer in the EPIC cohort study

New data regarding a positive association between smoking and risk of epithelial ovarian cancer (EOC), especially the mucinous tumor type, has started to emerge. The purpose of this study was to examine the association between different measures of smoking exposures and subtypes of EOC in a large cohort of women from 10 European countries. The European Prospective Investigation into Cancer and Nut

Effect of Medication on Microvascular Vasodilatation in Patients with Systemic Lupus Erythematosus

The aim of this study was to investigate the microvascular responses in the skin, to local heat, iontophoretically administered acetylcholine and to sodium nitroprusside in relation to cardiovascular damage in patients with systemic lupus erythematosus (SLE) and matched controls. We also wanted to examine if the ongoing medication in SLE patients influenced this vascular response. We investigated

Marital status, social capital, economic stress, and mental health: A population-based study

The associations between marital status and poor mental health are investigated, and whether social capital, trust, and economic stress attenuate the associations between marital status and poor mental health. The public health survey in Skane (southern Sweden) 2008 is a cross-sectional study including 28,198 persons aged 18-80. Logistic regression models investigate associations between marital s

Parental history and venous thromboembolism: a nationwide study of age and sex-specific familial risks in Sweden.

Background: The value of parental history as a risk indicator for venous thromboembolism (VTE) has not been determined in a nationwide setting. Objectives: This is the first nationwide study of age and sex specific familial VTE risks in offspring of parents hospitalized for VTE. Patients/Methods: The Swedish Multigeneration Register of 0-75-year-old subjects was linked to the Hospital Discharge Re

Genotyping should be considered the primary choice for pre-treatment evaluation of thiopurine methyltransferase function.

BACKGROUND AND AIMS: A pre-treatment determination of the thiopurine S-methyltransferase (TPMT) genotype or phenotype can identify patients at risk of developing severe adverse reactions from thiopurine treatment. The risk of misclassifying a patient might be dependent on the method used. The aim of this study was to investigate the concordance between TPMT genotyping and phenotyping. METHODS: T

Tighter Relaxations for Higher-Order Models based on Generalized Roof Duality

Many problems in computer vision can be turned into a large-scale boolean optimization problem, which is in general NP-hard. In this paper, we further develop one of the most successful approaches, namely roof duality, for approximately solving such problems for higher-order models. Two new methods that can be applied independently or in combination are investigated. The first one is based on cons

Arsenite adsorption on cryogels embedded with iron-aluminium double hydrous oxides: Possible polishing step for smelting wastewater?

Arsenic is among the most toxic elements and it commonly exists in water as arsenite (As(III)) and arsenate (As(V)) ions. As(III) removal often requires a pre-oxidation or pH adjustment step and it is a challenge to adsorb As(III) at circumneutral pH. In this study, iron-aluminium double hydrous oxides were synthesized and incorporated into cryogels. The resulting composite cryogels were evaluated

Prolonged half-life and preserved enzymatic properties of factor IX selectively PEGylated on native N-glycans in the activation peptide

Current management of hemophilia B entails multiple weekly infusions of factor IX (FIX) to prevent bleeding episodes. In an attempt to make a longer acting recombinant FIX (rFIX), we have explored a new releasable protraction concept using the native N-glycans in the activation peptide as sites for attachment of polyethylene glycol (PEG). Release of the activation peptide by physiologic activators
