Shuang Xu, Ramesh Attinti, Elizabeth Adams, Jie Wei, Kalmia Kniel, Jie Zhuang, Yan Jin
In this study, we quantified transport and retention behaviors of a human pathogenic virus (Adenovirus 41, abbreviated as Ad-41) and a model bacteriophage (ϕX174) through metal oxide-removed and goethite-coated sand under saturated flow conditions. Two sets of bench scale column experiments were conducted: transport of each type of viruses alone and co-transport of both viruses. All experiments were conducted at pH 7.5 using 2 mM artificial ground water (AGW) buffer as background solution. Experimental results revealed that goethite-coated sand (i...

BACKGROUND: Persistent gaming, despite acknowledgment of its negative consequences, is a major criterion for individuals with Internet gaming disorder (IGD). This study evaluated the adaptive decision-making, risky decision, and decision-making style of individuals with IGD. METHODS: We recruited 87 individuals with IGD and 87 without IGD (matched controls). All participants underwent an interview based on the Diagnostic and Statistical Manual of Mental Disorders (5th Edition) diagnostic criteria for IGD and completed an adaptive decision-making task; the Preference for Intuition and Deliberation Scale, Chen Internet Addiction Scale, and Barratt Impulsivity Scale were also assessed on the basis of the information from the diagnostic interviews...

At excess levels, zinc (Zn) disrupts mitochondrial functional integrity and induces oxidative stress in aquatic organisms. Although much is known about the modulation of Zn toxicity by calcium (Ca) in fish, their interactions at the mitochondrial level have scarcely been investigated. Here we assessed the individual and combined effects of Zn and Ca on the relationship between mitochondrial respiration, ROS and membrane potential (ΔΨmt) in rainbow trout liver mitochondria. We tested if cation uptake through the mitochondrial calcium uniporter (MCU) is a prerequisite for Zn- and/or Ca-induced alteration of mitochondrial function...

BACKGROUND: Health care personnel are expected to be familiar with evidence-based practice (EBP). Asking clinical questions, conducting systematic literature searches and conducting critical appraisal of research findings have been some of the barriers to EBP. To improve undergraduate nurses' research skills, a collaborative library-faculty teaching intervention was established in 2012. OBJECTIVES: The aim of this study was to evaluate how the collaborative library-faculty teaching intervention affected the nursing students' research skills when writing their final theses...

The polycyclic aromatic hydrocarbons (PAHs) concentrations in the water, suspended particulate matter (SPM) and sediment from the middle reaches of Huai River were analyzed by a gas chromatograph-mass spectrometer (GC-MS). The mean concentrations for the sum of 16 PAHs (∑16 PAHs) in the water, SPM and sediment were 1204 ng/L, 3192 ng/g (dry weight; dw), and 7955 ng/g (dw), respectively. Along the vertical profiles of water columns, higher ∑16 PAHs levels were seen in surface and bottom water layers and co-located SPM...

Inappropriate social behaviour is an early symptom of frontotemporal lobar degeneration (FTLD) in both behavioural variant frontotemporal dementia (bvFTD) and semantic dementia (SD) subtypes. Knowledge of social behaviour is essential for appropriate social conduct. The superior anterior temporal lobe (ATL) has been identified as one key neural component for the conceptual knowledge of social behaviour, but it is unknown whether this is dissociable from knowledge of the consequences of social behaviour. Here, we used a newly-developed test of knowledge about long-term and short-term consequences of social behaviour to investigate its impairment in patients with FTLD relative to a previously-developed test of social conceptual knowledge...

β-galactosidase (EC 3.2.1.23) are interesting enzymes able to catalyze lactose hydrolysis and transfer reactions to produce lactose-based prebiotics with potential application in the pharmaceutical and food industry. In this work, Aspergillus lacticoffeatus is described, for the first time, as an effective β-galactosidase producer. The extracellular enzyme production was evaluated in synthetic and alternative media containing cheese whey and corn steep liquor. Although β-galactosidase production occurred in all media (expect for the one composed solely by cheese whey), the highest enzymatic activity values (460U/mL) were obtained for the synthetic medium...

Sexual and reproductive health (SRH) care is often overlooked in advanced practice nursing educational programs, but advanced practice registered nurses are expected to provide care in this sensitive area. Competencies for SRH care were developed by the World Health Organization, and individual countries including the United States have adapted them to their unique health systems and populations. In this article, we discuss extant and future pathways for advanced practice registered nurses to develop competence in SRH care...

There is current uncertainty regarding the effects of mergers on pharmaceutical R&D productivity, with various mechanisms reported by which mergers could either help or harm R&D, and mixed empirical findings in prior analyses. Here, we present an analysis that is novel in several ways: we use downstream measures of R&D productivity, account for both inputs and outputs in our calculations, and use a self-controlled design. We find that recent large pharmaceutical mergers are associated with statistically significant increases in R&D productivity...

With increasing life expectancy more women with cystic fibrosis and diabetes mellitus become pregnant. We investigated how pre-gestational diabetes (cystic fibrosis related diabetes) influenced pregnancy outcome and the clinical status of these women MATERIAL AND METHODS: We analyzed all pregnancies reported to the French cystic fibrosis registry between 2001 and 2012, and compared forced expiratory volume (FEV1 ) and body mass index before and after pregnancy in women with and without pre-gestational diabetes having a first delivery RESULTS: A total 249 women delivered 314 infants...

Individuals do not have complete information about the environment and therefore they face a trade-off between gathering information (exploration) and gathering resources (exploitation). Studies have shown individual differences in components of this trade-off but how stable these strategies are in a population and the intrinsic drivers of these differences is not well understood. Top marine predators are expected to experience a particularly strong trade-off as many species have large foraging ranges and their prey often have a patchy distribution...

While marine protected areas (MPAs) can simultaneously contribute to biodiversity conservation and fisheries management, the global network is biased towards particular ecosystem types, as it was largely established in an ad hoc fashion. The optimization of trade-offs between biodiversity benefits and socio-economic values increases implementation success and minimizes enforcement costs in the long run, but is often neglected in marine spatial planning (MSP). Although the acquisition of spatially explicit socioeconomic data is often perceived as a costly/secondary step in MSP, it is critical to account for lost opportunities by people whose activities will be restricted, especially fishers...

The involvement of consumers in handover with nurses has been identified as reducing miscommunication and a reduction in adverse events in generalist nursing settings. Mental health (MH) care is complex, and handover practices need to fit with the philosophy of recovery-focussed practice. Recovery-focussed practice recognizes the person at the centre of care as an expert in their own treatment and decision-making. The aim of the present study was to explore the views of consumers with a mental illness, without prior involvement in nursing handover, about their need to be involved in nursing handover on an acute mental health inpatient unit...

Phenological changes are expected with the ongoing global warming, which could create mismatches in the growth patterns among sympatric species or create synchrony with insect herbivores. In this study, we performed a comparative assessment of the timings of bud break among seven conifer species of Eastern Canada by evaluating seedling development in growth chambers under different temperatures (16, 20 and 24 °C). Bud break occurred earliest in Larix laricina, while Pinus strobus and Pinus resinosa had the latest...

PURPOSE: Examining item usage is an important step in evaluating the performance of a computerized adaptive test (CAT). We study item usage for a newly developed multidimensional CAT which draws items from three PROMIS domains, as well as a disease-specific one. METHODS: The multidimensional item bank used in the current study contained 194 items from four domains: the PROMIS domains fatigue, physical function, and ability to participate in social roles and activities, and a disease-specific domain (the COPD-SIB)...

REVIEW
Marianne C Reddan, Tor D Wager
Pain is a subjective and complex phenomenon. Its complexity is related to its heterogeneity: multiple component processes, including sensation, affect, and cognition, contribute to pain experience and reporting. These components are likely to be encoded in distributed brain networks that interact to create pain experience and pain-related decision-making. Therefore, to understand pain, we must identify these networks and build models of these interactions that yield testable predictions about pain-related outcomes...

PURPOSE: This study aimed to examine how biomarker information would impact patients' preferences and physicians' recommendations for adjuvant breast cancer therapy. METHODS: At the 18-month follow-up, participants in a large, double-blind randomized controlled trial of adjuvant chemotherapy with bevacizumab or placebo (E5103) were surveyed about their preferred treatment (either chemotherapy A alone or chemotherapy A+B) in two hypothetical scenarios: (1) without biomarker information; and (2) after learning that they tested positive for a "B-receptor" which modestly increased both the benefit and toxicity expected with chemotherapy A+B...

Although insertion sequence (IS) elements are generally considered genomic parasites, they can mediate adaptive genetic changes in bacterial genomes. We discovered that among 12 laboratory-evolved Escherichia coli populations, three had experienced at least six different IS1-mediated deletions of flagellar genes. These deletions all involved the master flagellar regulator flhDC, and as such completely incapacitate motility. Two lines of evidence strongly suggest that these deletions were adaptive in our evolution experiment: (1) parallel evolution in three independent populations is highly unlikely just by chance, and (2) one of these deletion mutations swept to fixation within ~1000 generations, which is over two million times faster than expected if this deletion was instead selectively neutral and thus evolving by genetic drift...

This study attempts the development of an algorithm in order to present a step by step selection method for the location and the size of a waste-to-energy facility targeting the maximum output energy, also considering the basic obstacle which is in many cases, the gate fee. Various parameters identified and evaluated in order to formulate the proposed decision making method in the form of an algorithm. The principle simulation input is the amount of municipal solid wastes (MSW) available for incineration and along with its net calorific value are the most important factors for the feasibility of the plant...

Due to medical advances, a large portion of children survive brain tumor diagnosis and treatment. Therefore, it is important to identify the neuroanatomical and neurocognitive outcomes associated with survivorship. This review summarizes the specific regional structural neuroimaging findings, the broad structural findings, as well as the corresponding neurocognitive domains affected in brain tumor populations. Across studies, damage is commonly reported near the cerebellum, brain stem, and subcortical regions, as well as the frontal lobes...
