Mallory C Stites, Brennan R Payne, Kara D Federmeier
An important question in the reading literature regards the nature of the semantic information readers can extract from the parafovea (i.e., the next word in a sentence). Recent eye-tracking findings have found a semantic parafoveal preview benefit under many circumstances, and findings from event-related brain potentials (ERPs) also suggest that readers can at least detect semantic anomalies parafoveally (Barber, Van der Meij, & Kutas, Psychophysiology, 50(1), 48-59, 2013). We use ERPs to ask whether fine-grained aspects of semantic expectancy can affect the N400 elicited by a word appearing in the parafovea...

BACKGROUND: Quantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis. METHODS: Articles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12...

The present study was composed of two parts examining the clinical utility of the Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency and Color-Word subtests in traumatic brain injury (TBI). In the first part, the performance of 128 outpatients with mild to severe TBI on the Verbal Fluency and Color-Word subtests was examined in relation to two primary indicators of TBI severity: length of coma and the presence of intracranial lesions on neuroimaging through regression analysis. After controlling for education, ethnicity, and complicating premorbid and comorbid factors, length of coma predicted performance on the Color-Word Inhibition/Switching subtest, whereas the presence of diffuse lesions was related to Verbal Fluency Category Switching performance...

Fibrils formed by the β-amyloid (Aβ) peptide play a central role in the development of Alzheimer's disease. In this study, the principles governing their growth and stability are investigated by analyzing canonical and replica-exchange molecular dynamics trajectories of Aβ(9-40) fibrils. In particular, an unstructured monomer was allowed to interact freely with an Aβ fibril template. Trajectories were generated with the coarse-grained united-residue force field, and one- and two-dimensional free-energy landscapes (FELs) along the backbone virtual-bond angle θ and backbone virtual-bond-dihedral angle γ of each residue and principal components, respectively, were analyzed...

To review the literature about the use of Rabies Virus-Vaccine (RV-V) as an anticancer immunotherapeutic modality in the light of recent findings. The literature search in relevant databases with the following key words: Rabies virus, cancer, remission. Remissions occured following RV-V injections in patients with cervical cancer and melanoma. Pilot clinical studies showed that RV-V injections enhanced survival in glioblastoma patients, which is supported by findings in GL261 mouse glioma model. If public health studies demonstrate protective role of RV-V against certain types of cancers, it can be benefitted as a novel immune adjuvant in clinic...

Heather Dial, Randi Martin
Several studies have reported that aphasic patients may perform substantially better on lexical than sublexical perception tasks (e.g., Miceli, Gainotti, Caltagirone, & Masullo, 1980). These findings challenge claims made by models of speech perception which assume obligatory sublexical processing (e.g., McClelland & Elman, 1986; Norris, 1994). However, prior studies have not closely matched the phonological similarity of targets and distractors or task demands of the sublexical and lexical perception tasks...

During the progression of pancreatic ductal adenocarcinoma (PDAC), heterogeneous subclonal populations emerge that drive primary tumor growth, regional spread, distant metastasis, and patient death. However, the genetics of metastases largely reflects that of the primary tumor in untreated patients, and PDAC driver mutations are shared by all subclones. This raises the possibility that an epigenetic process might operate during metastasis. Here we report large-scale reprogramming of chromatin modifications during the natural evolution of distant metastasis...

Richard Stephens, Amy Zile
This study assessed the effect of experimentally manipulated emotional arousal on swearing fluency. We hypothesised that swear word generation would be increased with raised emotional arousal. The emotional arousal of 60 participants was manipulated by having them play a first-person shooter video game or, as a control, a golf video game, in a randomised order. A behavioural measure of swearing fluency based on the Controlled Oral Word Association Test was employed. Successful experimental manipulation was indicated by raised State Hostility Questionnaire scores after playing the shooter game...

OBJECTIVE: The Outcome Measures in Rheumatology (OMERACT) Shoulder Core Outcome Set Special Interest Group (SIG) was established to develop a core outcome set (COS) for clinical trials of shoulder disorders. METHODS: In preparation for OMERACT 2016, we systematically examined all outcome domains and measurement instruments reported in 409 randomized trials of interventions for shoulder disorders published between 1954 and 2015. Informed by these data, we conducted an international Delphi consensus study including shoulder trial experts, clinicians, and patients to identify key domains that should be included in a shoulder disorder COS...

In resting-state functional MRI (rsfMRI), the correlation between blood oxygenation level dependent (BOLD) signals across different brain regions is used to estimate the functional connectivity of the brain. This approach has led to the identification of a number of resting-state networks, including the default mode network (DMN) and the task positive network (TPN). Global signal regression (GSR) is a widely used pre-processing step in rsfMRI that has been shown to improve the spatial specificity of the estimated resting-state networks...

There is marked variability in both onset and rate of episodic-memory decline in aging. Structural magnetic resonance imaging studies have revealed that the extent of age-related brain changes varies markedly across individuals. Past studies of whether regional atrophy accounts for episodic-memory decline in aging have yielded inconclusive findings. Here we related 15-year changes in episodic memory to 4-year changes in cortical and subcortical gray matter volume and in white-matter connectivity and lesions...

The adequacy of three competing theories of hormonal effects on cerebral laterality are compared using functional transcranial Doppler sonography (fTCD). Thirty-three adult males participated in the study (21 left-handers). Cerebral lateralization was measured by fTCD using an extensively validated word generation task. Adult salivary testosterone (T) and cortisol (C) concentrations were measured by luminescence immunoassay and prenatal T exposure was indirectly estimated by the somatic marker of 2nd to 4th digit length ratio (2D:4D)...

Sentences encode hierarchical structural relations among words. Several neuroimaging experiments aiming to localize combinatory operations responsible for creating this structure during sentence comprehension have contrasted short, simple phrases and sentences to unstructured controls. Some of these experiments have revealed activation in the left inferior frontal gyrus (IFG) and posterior superior temporal sulcus (pSTS), associating these regions with basic syntactic combination. However, the wide variability of these effects across studies raises questions about this interpretation...

Melanie S Schreiner, Nivedita Mani
While American English infants typically segment words from fluent speech by 7.5-months, studies of infants from other language backgrounds have difficulty replicating this finding. One possible explanation for this cross-linguistic difference is that the input infants from different language backgrounds receive is not as infant-directed as American English infant-directed speech (Floccia et al., 2016). Against this background, the current study investigates whether German 7.5- and 9-month-old infants segment words from fluent speech when the input is prosodically similar to American English IDS...

BACKGROUND: The teaching of trauma in medical schools faces many educational and logistic challenges. Issues on what to teach, how to teach, when to teach, who will teach and whether medical students with insufficient exposure to clinical medicine can benefit from a trauma course are unclear. MATERIALS AND METHODS: A well-designed one day intensive trauma course concentrating on the primary survey was taught to semester seven and semester eight students by a multi-disciplinary team comprising of surgeons, anaesthetists, emergency physicians and trained medical officers...

Few investigations of lexical access in spoken word production have investigated the cognitive and neural mechanisms involved in action naming. These are likely to be more complex than the mechanisms involved in object naming, due to the ways in which conceptual features of action words are represented. The present study employed a blocked cyclic naming paradigm to examine whether related action contexts elicit a semantic interference effect akin to that observed with categorically related objects. Participants named pictures of intransitive actions to avoid a confound with object processing...

This study examined preferences and ascriptions of human control for avatars associated with positive and negative language. An avatar is a graphical representation of an individual user in a virtual world. Users form judgments of other virtual world users based on the appearance and behavior of their avatars in the absence of physical cues. In particular, users have previously displayed sensitivity toward anthropomorphism and verbal behavior of avatars they encounter within virtual environments. Thus far, investigations of language in online and virtual spaces have been limited to specific contexts...

Statistical learning is often considered to be a means of discovering the units of perception, such as words and objects, and representing them as explicit "chunks." However, entities are not undifferentiated wholes but often contain parts that contribute systematically to their meanings. Studies of incidental auditory or visual statistical learning suggest that, as participants learn about wholes they become insensitive to parts embedded within them, but this seems difficult to reconcile with a broad range of findings in which parts and wholes work together to contribute to behavior...

Research shows that when semantic context makes it feel easier for people to bring related thoughts and images to mind, people can misinterpret that feeling of ease as evidence that information is positive. But research also shows that semantic context does more than help people bring known concepts to mind-it also teaches people new concepts. In five experiments, we show that when photos increase these feelings of learning, they also increase positive evaluations. People saw fictitious wine names and evaluated claims about each...
