Escherichia coli O104:H4, a Shiga toxin-producing hybrid pathotype that was implicated in a major foodborne outbreak in Germany in 2011, has not been detected in cattle. However, serotypes of O104, other than O104:H4, have been isolated from cattle feces, with O104:H7 being the most predominant. In this study, we investigated, based on whole genome sequence analyses, the virulence potential of E. coli O104 strains isolated from cattle feces, since cattle are asymptomatic carriers of E. coli O104. The genomes of ten bovine E...

All of the AB_{2} Laves phases discovered so far satisfy the general crystalline structure characteristic of translational symmetry; however, we report here a new structured Laves phase directly precipitated in an aged Mg-In-Ca alloy by using aberration-corrected scanning transmission electron microscopy. The nanoprecipitate is determined to be a (Mg,In)_{2}Ca phase, which has a C14 Laves structure (hcp, space group: P6_{3}/mmc, a=6.25  Å, c=10.31  Å) but without any translational symmetry on the (0001)_{p} basal plane...

Stalagmites play an important role in paleoclimatic reconstructions from seasonal to orbital time scales as230 Th-dating can provide an accurate absolute age. Additionally, seasonal trace element and optical layers can provide a precise age. We analyzed the seasonal variability of multiple trace elements on a stalagmite (XMG) in Shihua Cave, Beijing and compared them with results from laminae counting. The results show that (1) the polished section of the topmost part of XMG has obvious bi-optical layers under a conventional transmission microscope, however, laminae are not observed using this method in the rest of the sample, and (2) The variations of P/Ca, Sr/Ca, Ba/Ca, U/Ca and Mg/Ca show seasonal cycles throughout the sample...

Exposure-based Cognitive Behavioral Therapy (eb-CBT) represents the most evidence-based psychotherapeutic approach in anxiety disorders. However, its efficacy may be limited by a delay in onset of action and a substantial number of patients does not respond sufficiently to treatment. In this context, aerobic exercise was found to be effective in reducing clinical anxiety as well as to improve (elements of) disorder-specific CBT in some mental disorders. We therefore investigated the effect of aerobic exercise supplementary to an eb-CBT in panic disorder and agoraphobia (PD/AG)...

The Cretaceous-Palaeogene (K-Pg) mass extinction is linked to the rapid emergence of ecologically divergent higher taxa (for example, families and orders) across terrestrial vertebrates, but its impact on the diversification of marine vertebrates is less clear. Spiny-rayed fishes (Acanthomorpha) provide an ideal system for exploring the effects of the K-Pg on fish diversification, yet despite decades of morphological and molecular phylogenetic efforts, resolution of both early diverging lineages and enormously diverse subclades remains problematic...

Background: Self-monitoring (SM) of diet and tailored feedback (TF) have been suggested as tools for changing dietary behavior. New technologies allow users to monitor behavior remotely, potentially improving reach, adherence, and outcomes. Objective: We conducted a systematic literature review and meta-analysis to address the following question: are remotely delivered standalone (i.e., no human contact) interventions that use SM or TF effective in changing eating behaviors? Design: Five databases were searched in October 2016 (updated in September 2017)...

BACKGROUND: In the western world, a growing number of the older people live at home. In the Netherlands, GPs are expected to play a pivotal role in the organization of integrated care for this patient group. However, little is known about how GPs can play this role best. Our aim for this study was to unravel how GPs can play a successful role in elderly care, in particular in multidisciplinary teams, and to define key concepts for success. METHODS: A mixed qualitative research model in four multidisciplinary teams for elderly care in the Netherlands was used...

Among the earliest Homo sapiens societies in Eurasia, the Aurignacian phase of the Early Upper Palaeolithic, approximately 40,000-30,000 uncal. BP, mammoth ivory assumed great social and economic significance, and was used to create hundreds of personal ornaments as well as the earliest known works of three-dimensional figurative art in the world. This paper reports on the results of micro-PIXE/PIGE analyses of mammoth-ivory artefacts and debris from five major sites of Aurignacian ivory use. Patterns of variable F-content indicate regionally-distinct strategies of ivory procurement that correspond to apparent differences in human-mammoth interactions...

INTRODUCTION: Hydralazine is an antihypertensive medication that has been associated with drug-induced lupus erythematosus (DIL) as well as ANCA-associated vasculitis (AAV). Although rare, early diagnosis is critical since drug cessation is the mainstay of therapy. This retrospective study aims to characterize the clinical, laboratory, and histopathologic features of this disease. METHODS: Once approval was obtained from the Institutional Review Board at the University of Iowa, all patients carrying a diagnosis of vasculitis (ICD9 code: 447...

Plant glutathione peroxidases (GPXs) are non-heme thiol peroxidases that play vital roles in maintaining H2 O2 homeostasis and regulating plant response to abiotic stress. Here, we performed a comparative genomic analysis of the GPX gene family in cucumber ( Cucumis sativus ). As a result, a total of 6 CsGPX genes were identified, which were unevenly located in four out of the seven chromosomes in cucumber genome. Based on the phylogenetic analysis, the GPX genes of cucumber, Arabidopsis and rice could be classified into five groups...
