Influenza is responsible for up to 500,000 deaths every year, and antigenic variability represents much of its epidemiological burden. To visualize antigenic differences across many viral strains, antigenic cartography methods use multidimensional scaling on binding assay data to map influenza antigenicity onto a low-dimensional space. Analysis of such assay data ideally leads to natural clustering of influenza strains of similar antigenicity that correlate with sequence evolution. To understand the dynamics of these antigenic groups, we present a framework that jointly models genetic and antigenic evolution by combining multidimensional scaling of binding assay data, Bayesian phylogenetic machinery and nonparametric clustering methods...

OBJECTIVE: Significant levels of anxiety, depression and insomnia symptoms are found in cancer patients. Perfectionism, arousability and coping have been associated with these psychological symptoms in the general population but their role among cancer patients remains to be assessed. This study examined the longitudinal relationships between perfectionism and psychological symptoms (anxiety, depression, insomnia), and the intermediate role of the arousability trait and coping strategies...

High-valent Cu and Fe species, which are generated from dioxygen activation in metalloenzymes, carry out the functionalization of strong C-H bonds. Understanding the atomic details of the catalytic mechanism has long been one of the main objectives of bioinorganic chemistry. Large H/D kinetic isotope effects (KIEs) were observed in the C-H activation by high-valent non-heme Cu or Fe complexes in enzymes and their synthetic models. The H/D KIE depends significantly on the transition state properties, such as structure, energies, frequencies, and shape of the potential energy surface, when the tunneling effect is large...

The paper shows the importance of serendipity and exaptation in selected key moments of ageing research and argue that rationalistic dominant models in scientific research have masked the importance of reverse models of discovery based on serendipity and exaptation. I ask why this is the case and analyze three contributing factors: unprestatability of the functions of technologies, multidimensionality and astronomical complexity of the space over which biological reactions occurs and role of scientific paradigms in channeling research toward incrementalism...

BACKGROUND: Health-related quality of life (HRQL) is a key indicator of elderly people's health status that can be affected by different factors. However, little is known about which variables are associated with it in functionally independent elderly people. The aim of this project was to study HRQL and a wide variety of health, lifestyle, social and contextual aspects and their relation to HRQL in a sample of functionally independent, non-cognitively impaired community-dwelling adults, over 65 years of age, from a northern region of Spain...

Molecular networks governing cellular responses to targeted therapies are complex dynamic systems with non-intuitive behaviors. Here we applied a novel computational strategy to infer probabilistic causal relationships between network components based on gene expression. We constructed a model comprised of an ensemble of networks using multidimensional data from cell line models of cell cycle arrest caused by inhibition of MEK1/2. Through simulation of reverse-engineered Bayesian network modeling, we generated predictions of G1-S transition...

Preeclampsia, a pregnancy-specific disorder, shares typical pathophysiological features with protein misfolding disorders including Alzheimer's disease. Characteristic for preeclampsia is the involvement of multiple proteins of which fragments of SERPINA1 and β-amyloid co-aggregate in urine and placenta of preeclamptic women. To explore the biophysical basis of this interaction, we investigated the multidimensional efficacy of the FVFLM sequence in SERPINA1, as a model inhibitory agent of β-amyloid aggregation...

Key research suggests that empathy is a multidimensional construct comprising of both cognitive and affective components. More recent theories and research suggest even further factors within these components of empathy, including the ability to empathize with others versus the drive towards empathizing with others. While numerous self-report measures have been developed to examine empathy, none of them currently index all of these wider components together. The aim of the present research was to develop and validate the Empathy Components Questionnaire (ECQ) to measure cognitive and affective components, as well as ability and drive components within each...

PURPOSE: The need for all providers to deliver basic palliative care has emerged as patients' needs outstrip the capacity of specialty palliative care. Many patients with complex illnesses have unmet needs and are seen in primary care more than other settings. We explore primary care providers' willingness and perceived capacity to provide basic palliative care, and their concerns and perceived barriers. METHODS: We performed semistructured telephone interviews with 20 primary care providers about their perceptions of palliative care, including needs, practices, experiences, access, and what would be helpful for their practices to systematically provide basic palliative care...

INTRODUCTION: Since Lezak coined the term executive functions to refer to the mental capabilities that are considered essential for performing efficacious, creative and socially acceptable behaviour, they have gradually grown in importance in neuropsychological research. Different models have been proposed to explain their nature, but there is no general agreement as to whether we are dealing with a unitary construct or a multimodal processing system with independent, but interconnected, components...

The electroencephalography (EEG) data created in event-related potential (ERP) experiments have a complex high-dimensional structure. Each stimulus presentation, or trial, generates an ERP waveform which is an instance of functional data. The experiments are made up of sequences of multiple trials, resulting in longitudinal functional data and moreover, responses are recorded at multiple electrodes on the scalp, adding an electrode dimension. Traditional EEG analyses involve multiple simplifications of this structure to increase the signal-to-noise ratio, effectively collapsing the functional and longitudinal components by identifying key features of the ERPs and averaging them across trials...

Progranulin (PGRN) is implicated in Alzheimer's disease (AD) as well as frontotemporal lobar degeneration. Genetic studies demonstrate an association of the common GRN rs5848 variant that results in reduced PGRN levels with increased risk for AD. However, the mechanisms by which PGRN reduction from the GRN AD risk variant or mutation exacerbates AD pathophysiology remain ill defined. Here, we show that the GRN AD risk variant has no significant effects on florbetapir positron emission tomographic amyloid imaging and cerebrospinal fluid (CSF) Aβ levels, whereas it is associated with increased CSF tau levels in human subjects of the Alzheimer's disease neuroimaging initiative studies...

BACKGROUND: Nurses' intention to leave their profession is a worldwide concern. Studies have shown that it can take the form of a chain reaction: many nurses first leave the unit, then the hospital, and finally the profession. Organisation and other labour factors, personal and conjunctural, have been associated with the intention to quit nursing. This study aimed to examine the factors associated with the intention to leave the profession among registered nurses (RNs) at large public hospitals in Brazil...

This article presents the development and psychometric evaluation of the Internalized Racism in Asian Americans Scale (IRAAS), which was designed to measure the degree to which Asian Americans internalized hostile attitudes and negative messages targeted toward their racial identity. Items were developed on basis of prior literature, vetted through expert feedback and cognitive interviews, and administered to 655 Asian American participants through Amazon Mechanical Turk. Exploratory factor analysis with a random subsample (n = 324) yielded a psychometrically robust preliminary measurement model consisting of 3 factors: Self-Negativity, Weakness Stereotypes, and Appearance Bias...
