#1
Maria Kaufmann, Mark Wiering
Flood risks are managed differently across Europe. While a number of research studies aim to understand these differences, they tend to pay little attention to the social constructionist aspects of flood risk governance, i.e. the meaning that societies give to flood risk and governance. This paper aims to address this gap by understanding differences in flood risk management approaches (FRMA) from a discursive-institutional perspective. Based on this perspective, an analytical framework was developed to systematically analyse and compare discourses pertaining to flood risk and its governance in six European member states (England (the United Kingdom), Flanders (Belgium), France, the Netherlands, Poland and Sweden)...

Understanding the brain circuitry that underlies reward is critical to improve treatment for many common health issues, including obesity, depression, and addiction. Here we focus on insights into the organization and function of reward circuitry and its synaptic and structural adaptations in response to cocaine exposure. While the importance of certain circuits, such as the mesocorticolimbic dopamine pathway, are well established in drug reward, recent studies using genetics-based tools have revealed functional changes throughout the reward circuitry that contribute to different facets of addiction, such as relapse and craving...

In patients with haematological malignancies, the bowel remains the main source of Escherichia coli bloodstream infections. We present the clinical example of recurrent bowel-blood translocations of E. coli with the unique virulence characteristics in a 55-year-old male with the diagnosis of acute myeloid leukaemia. The virulent factors profile of examined strains confirmed that the co-existence of genes papC, sfa, usp and cnf1, encoding virulence factors, predisposes E. coli to translocation from the gastrointestinal tract to the vascular bed...

OBJECTIVE: High sensitivity plasma cardiac troponin-I (cTnI) is emerging as a strong predictor of cardiac events in a variety of settings. We have explored its utility in patients with myotonic dystrophy type 1 (DM1). METHODS: 117 patients with DM1 were recruited from routine outpatient clinics across three health boards. A single measurement of cTnI was made using the ARCHITECT STAT Troponin I assay. Demographic, ECG, echocardiographic and other clinical data were obtained from electronic medical records...

Equity, defined as reward according to contribution, is considered a central aspect of human fairness in both philosophical debates and scientific research. Despite large amounts of research on the evolutionary origins of fairness, the evolutionary rationale behind equity is still unknown. Here, we investigate how equity can be understood in the context of the cooperative environment in which humans evolved. We model a population of individuals who cooperate to produce and divide a resource, and choose their cooperative partners based on how they are willing to divide the resource...

OBJECTIVES: Associations between parental occupational pesticide exposure and childhood acute lymphoblastic leukemia (ALL) vary across studies, likely due to different exposure assessment methodologies. METHODS: We assessed parental occupational pesticide exposure from the year before pregnancy to the child's third year of life for 669 children diagnosed with ALL and 1021 controls. We conducted expert rating using task-based job modules (JM) to estimate exposure to pesticides among farmer workers, gardeners, agricultural packers, and pesticide applicators...

Patients who received a total artificial heart (TAH) at Virginia Commonwealth University (VCU) between January 1, 2010 and December 31, 2011 were identified from the VCU Mechanical Circulatory Support Clinical Database. Retrospective data extraction from the medical records was performed from the time of TAH implantation until heart transplantation or death. Infections were classified as confirmed or suspected. Twenty-seven men and 5 women, mean age 49.5 years (range 24 to 68 years) received a TAH. The mean duration of TAH support was 225 days (range 1 to 1334 days)...

The Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) initiative was launched in an effort to address specific gaps in the understanding of the psychosocial impact of mild-moderate-severe hemophilia B. The original Hemophilia Experiences, Results and Opportunities (HERO) qualitative study evaluated the needs of people with hemophilia A or B in multiple countries; however, a majority of participants had the more common moderate-severe hemophilia A. The B-HERO-S study was designed in collaboration with the hemophilia community to evaluate the needs of adults with hemophilia B and caregivers of children with hemophilia B, including affected women and caregivers of girls with hemophilia...

The psychosocial impact of hemophilia on work was recently investigated in the Hemophilia Experiences, Results and Opportunities (HERO) study. The findings revealed that hemophilia had an impact for adults with moderate/severe hemophilia and caregivers of children with hemophilia. HERO did not specifically evaluate impact on education in adults/children with mild/moderate hemophilia or the impact on employment of spouses/partners of caregivers of affected children. The Bridging Hemophilia B Experiences, Results and Opportunities into Solutions (B-HERO-S) study evaluated the impact of hemophilia on the lives of adult men/women with mild-severe hemophilia B and caregivers of boys/girls with hemophilia B and their spouses/partners...

The psychosocial impact of hemophilia on activities was recently investigated in the Hemophilia Experiences, Results and Opportunities (HERO) study (675 people with hemophilia and 561 caregivers of children with hemophilia in 10 countries). The impact of hemophilia B may not be accurately reflected in the HERO results, as ~75% of respondents described issues affecting males with hemophilia A. To address the needs of this population, the Bridging Hemophilia B Experiences, Results and Opportunities Into Solutions (B-HERO-S) was developed as a pilot study in the United States in collaboration with the hemophilia community...

Self-renewing naive mouse embryonic stem cells (mESCs) contain few mitochondria, which increase in number and volume at the onset of differentiation. KBP (encoded by Kif1bp) is an interactor of the mitochondrial-associated kinesin Kif1Bα. We found that TDH, responsible for mitochondrial production of acetyl-CoA in mESCs, and the acetyltransferase GCN5L1 cooperate to acetylate Lys501 in KBP, allowing its recognition by and degradation via Fbxo15, an F-box protein transcriptionally controlled by the pluripotency core factors and repressed following differentiation...

The overwhelming number of genetic alterations identified through cancer genome sequencing requires complementary approaches to interpret their significance and interactions. Here we developed a novel whole-body insertional mutagenesis screen in mice, which was designed for the discovery of Pten-cooperating tumor suppressors. Toward this aim, we coupled mobilization of a single-copy inactivating Sleeping Beauty transposon to Pten disruption within the same genome. The analysis of 278 transposition-induced prostate, breast and skin tumors detected tissue-specific and shared data sets of known and candidate genes involved in cancer...

Loss of phosphatase and tensin homolog (PTEN) and activation of the PI3K/AKT signaling pathway are hallmarks of prostate cancer (PCa). However, these alterations alone are insufficient for cells to acquire metastatic traits. Here, we have shown that the histone dimethyl transferase WHSC1 critically drives indolent PTEN-null tumors to become metastatic PCa. In a PTEN-null murine PCa model, WHSC1 overexpression in prostate epithelium cooperated with Pten deletion to produce a metastasis-prone tumor. Conversely, genetic ablation of Whsc1 prevented tumor progression in PTEN-null mice...

BACKGROUND: Periprosthetic joint infection (PJI) is a serious complication of total hip arthroplasty (THA). Although the number of revision cases is increasing, the prevalence of PJI as an indication for revision surgery, and the variability of this indication among surgeons and hospitals, is unclear. METHODS: The New York Statewide Planning and Research Cooperative System was used to identify 33,582 patients undergoing revision THA between 2000 and 2013. PJI was identified using International Classification of Diseases, Ninth Revision diagnosis codes...

The objective of this study was to compare central line-associated bloodstream infection (CLABSI) rates in Gulf Cooperation Council (GCC) states with those of the U.S. National Healthcare Safety Network (NHSN) and International Nosocomial Infection Control Consortium (INICC) using pooled data from 6 hospitals in 3 GCC countries. The overall CLABSI rate was 3.1 per 1,000 central line days. After adjusting for differences in intensive care unit types, the risk of CLABSI in GCC hospitals was 146% higher than NHSN hospitals but 33% lower than INICC hospitals...

INTRODUCTION: The aim of this study was to evaluate the incidence and severity of blunt cardiac injury (BCI) as determined by cardiac magnetic resonance imaging (CMR), and to compare this to currently used diagnostic methods in severely injured patients. MATERIALS AND METHODS: We conducted a prospective, pilot cohort study of 42 major trauma patients from July 2013 to Jan 2015. The cohort underwent CMR within 7 days, enrolling 21 patients with evidence of chest injury and an elevated Troponin I compared to 21 patients without chest injury who acted as controls...

Eukaryotes possess a vast array of RNA-binding proteins (RBPs) that affect mRNAs in diverse ways to control protein expression. Combinatorial regulation of mRNAs by RBPs is emerging as the rule. No example illustrates this as vividly as the partnership of three Drosophila RBPs, Pumilio, Nanos and Brain Tumor, which have overlapping functions in development, stem cell maintenance and differentiation, fertility and neurological processes. Here we synthesize thirty years of research with new insights into their molecular functions and mechanisms of action...

Hydrogen-rich compounds are important for understanding the dissociation of dense molecular hydrogen, as well as searching for room temperature Bardeen-Cooper-Schrieffer (BCS) superconductors. A recent high pressure experiment reported the successful synthesis of novel insulating lithium polyhydrides above 130 GPa. However, the results are in sharp contrast to a previous theoretical prediction by the PBE functional that around this pressure range all lithium polyhydrides (LiHn (n = 2-8)) should be metallic...

Cluster formation of ammonia borane (NH3BH3) driven by non-covalent H...H dihydrogen interaction is investigated at M06L/6-311+G(d,p) level density functional theory. For clusters containing up to six monomers, ladder, cyclic, stacked, cross-stacked, end-on, mixed and hexagonal configurations have been screened for their energetic stability. In the dimer, 7.94 kcal/mol stabilization energy per monomer (E(m)) is observed. Compared to ladder and cyclic configurations, a tetramer consisting of stacked dimer units is more stable by 3...
