Virulence of pathogenic bacteria is a tightly controlled process to facilitate invasion and survival in host tissues. Although pathways controlling virulence have been defined in detail, signals modulating these processes are poorly understood. The opportunistic pathogen Pseudomonas aeruginosa causes acute and chronic infections in humans. Disease progression is typically associated with a loss of acute virulence and the emergence of biofilms and chronic behaviour. The acute-to-chronic switch is governed by the global Gac/Rsm pathway...

We contribute an investigation of the design and function of word-scale graphics and visualizations embedded in text documents. Word-scale graphics include both data-driven representations such as word-scale visualizations and sparklines, and non-data-driven visual marks. Their design, function, and use has so far received little research attention. We present the results of an open ended exploratory study with 9 graphic designers. The study resulted in a rich collection of different types of graphics, data provenance, and relationships between text, graphics, and data...

Personality disorders (PDs) are inherently associated with deficits in relating to other people. Previous research has shown consistent negative associations between categorical PD symptoms and relationship satisfaction. The present studies extend on these findings by examining the role of maladaptive traits in a number of ways. Self- and partner-reported maladaptive traits of both partners are included. Moreover, the present studies add a couple-centered approach by investigating the effects of actual similarity, perceptual similarity, and perceptual accuracy of the maladaptive trait profile on relationship satisfaction...

As speakers interact, they add references to their common ground, which they can then reuse to facilitate listener comprehension. However, all references are not equally likely to be reused. The purpose of this study was to shed light on how the speakers' conceptualizations of the referents under discussion affect reuse (along with a generation effect in memory documented in previous studies on dialogic reuse). Two experiments were conducted in which participants interactively added references to their common ground...

Research has consistently shown that actuarial measures are superior to unstructured clinical judgments in predicting recidivism of offenders. However, in a non-Western context, clinical judgment may capture contextually relevant risk-related factors. The purpose of the current research is to investigate the incremental value of clinical risk judgment in a sample of Japanese youths. With a sample of 299 released youths, the relative accuracy of the actuarial predictor (Youth Level of Service/Case Management Inventory [YLS/CMI]) and unstructured clinical judgment (recommendation of placement by psychologists) was examined...

BACKGROUND: Employment is an important part of recovery for individuals with schizophrenia. The employment rate for this group is as low as 10% in Norway, and major system related barriers to employment are evident. AIMS: This study reports the competitive employment outcome at 2-year follow-up of a vocational rehabilitation study augmented with cognitive remediation (CR) or elements from cognitive behaviour therapy (CBT) for individuals with schizophrenia spectrum disorders...

: WHAT IS KNOWN ON THE SUBJECT?: Panic disorder patients display various panic-related physical symptoms and catastrophic misinterpretation of bodily sensations, which lower their quality of life by interfering with daily activities. Cognitive behavioural therapy (CBT) is a useful strategy for panic disorder patients to manage symptoms associated with inaccurate cognitive interpretation of situations resulting from the patient's cognitive vulnerability. In South Korea, however, despite the increasing prevalence of panic disorder, CBT is not a common element of nursing care plans for panic disorder patients...

In two experiments, we investigated observational learning in social relationships as one possible pathway to the development of goal adjustment processes. In the first experiment, 56 children (M = 9.29 years) observed their parent as a model; in the second, 50 adults (M = 32.27 years) observed their romantic partner. Subjects were randomly assigned to three groups: goal engagement (GE), goal disengagement (GD), or control group (CO) and were asked to solve (unsolvable) puzzles. Before trying to solve the puzzles by themselves, subjects observed the instructed model, who was told to continue with the same puzzle (GE) or to switch to the next puzzle (GD)...

In this study, preschool-aged children's lie-telling behaviour was examined in relation to mental state understanding and executive functioning. Sixty-seven children aged between 25 and 43 months (Mage in months  = 34.80, SD = 4.39) participated in a temptation resistance paradigm (TRP). Children completed emerging ToM tasks measuring the following mental states: (1) diverse beliefs, (2) diverse desires, and (3) knowledge access. Children also completed measures of inhibitory control and working memory...

Tapeworms (cestodes) are segmented flatworms responsible for causing diseases that may prove fatal and difficult to treat in the absence of proper treatment and efficient drugs. Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system and a major contributor to epilepsy caused by the metacestode (larva) of the human tapeworm Taenia solium, characterized by a range of pathological symptoms including epileptic seizures, headaches, and hydrocephalus. Cysticercosis is considered as a "biological imprint" of the socioeconomic development of a community in general and a country in particular...

The proliferation of cardiac-related biomarkers and advocacy for their use has often come without adequate discussion of limitations in the interpretation of values and their best use in heart failure (HF) patients to provide a balanced assessment of how cardiac biomarkers are advocated for use in HF and areas where we would argue there are no gaps in knowledge. We include suggestions to address these issues. We have focused on peer-reviewed publications over the period 2000 to present. Most studies have used samples at one or at most two points in time to define risk...

AIMS: Peripartum cardiomyopathy (PPCM) is a major cause of acute heart failure in the peripartum period and considered potentially life threatening. While many aspects of its clinical profiles have been frequently reported, functional analysis, in particular of the right ventricle, and tissue characterization by cardiovascular magnetic resonance (CMR) imaging have been only sporadically described. The aim of the present study was to analyse pathological alterations and their prognostic relevance found in CMR imaging of patients newly diagnosed with PPCM...

BACKGROUND: Acute heart failure (AHF) is a leading cause of death in critically ill patients and is often accompanied by significant renal dysfunction. Few data exist on the predictive value of measures of renal dysfunction in large cohorts of patients hospitalized for AHF. METHODS: Six hundred and eighteen patients hospitalized for AHF (300 male, aged 73.3 ± 10.3 years, 73% New York Heart Association Class 4, mean hospital length of stay 12.9 ± 7.7 days, 97% non-ischaemic AHF) were included in a retrospective single-centre data analysis...

Concurrent recording of electroencephalography (EEG) during transcranial magnetic stimulation (TMS) is an emerging and powerful tool for studying brain health and function. Despite a growing interest in adaptation of TMS-EEG across neuroscience disciplines, its widespread utility is limited by signal processing challenges. These challenges arise due to the nature of TMS and the sensitivity of EEG to artifacts that often mask TMS-evoked potentials (TEP)s. With an increase in the complexity of data processing methods and a growing interest in multi-site data integration, analysis of TMS-EEG data requires the development of a standardized method to recover TEPs from various sources of artifacts...

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

The RNA modification N6-methyladenosine (m(6)A) post-transcriptionally regulates RNA function. The cellular machinery that controls m(6)A includes methyltransferases and demethylases that add or remove this modification, as well as m(6)A-binding YTHDF proteins that promote the translation or degradation of m(6)A-modified mRNA. We demonstrate that m(6)A modulates infection by hepatitis C virus (HCV). Depletion of m(6)A methyltransferases or an m(6)A demethylase, respectively, increases or decreases infectious HCV particle production...

In this study, liquid culture systems containing rhamnolipid-solubilized, separate-phase, and multi-state hexadecane as the carbon source were employed for examining the effect of rhamnolipid solubilization on the bioavailability of hexadecane. Experimental results showed that the uptake of rhamnolipid-solubilized hexadecane by Pseudomonas aeruginosa ATCC 9027, a rhamnolipid producing strain, was enhanced compared to the uptake of mass hexadecane as a separate phase, indicating rhamnolipid solubilization increased the bioavailability of hexadecane for this bacterium...

Traumatic brain injury (TBI) is a devastating disorder, causing negative outcomes in millions of people each year. Despite the alarming numbers of brain injuries, and the long-term detrimental outcomes that can be associate with TBI, treatment options are lacking. Extensive investigation is underway, in hopes of identifying effective treatment strategies. Among the most state-of-the-art strategies is cell replacement therapy. TBI is a seemingly good candidate for cell replacement studies, because there is often neuron loss...

In this study, the influence of cholesterol on lipid bilayers is investigated by changing phospholipid head group, cholesterol concentration, chain saturation, and temperature. Molecular dynamics (MD) simulations were used to characterize bilayers containing phosphatidylcholine (PC) head groups with either fully saturated dimyristoyl (DM) or monounsaturated dioleoyl (DO) acyl chains and cholesterol concentrations ranging from 5-50%. To further explore the effects of cholesterol on bilayers with different head groups, we also preformed MD simulations of bilayer systems having 15% cholesterol with phosphatidic acid (PA), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), phosphatidylinositol (PI), and phosphatidylserine (PS), each having DM chains and at a temperature above the solid gel phase transition...
