Rational numbers: Componential versus holistic representation of fractions in a magnitude comparison task

This study investigated whether the mental representation of the fraction magnitude was componential and/or holistic in a numerical comparison task performed by adults. In Experiment 1, the comparison of fractions with common numerators (x/a_x/b) and of fractions with common denominators (a/x_b/x) primed the comparison of natural numbers. In Experiment 2, fillers (i.e., fractions without common components) were added to reduce the regularity of the stimuli. In both experiments, distance effects indicated that participants compared the numerators for a/x_b/x fractions, but that the magnitudes of the whole fractions were accessed and compared for x/a_x/b fractions. The priming effect of x/a_x/b fractions on natural numbers suggested that the interference of the denominator magnitude was controlled during the comparison of these fractions. These results suggested a hybrid representation of their magnitude (i.e., componential and holistic). In conclusion, the magnitude of the whole fraction can be accessed, probably by estimating the ratio between the magnitude of the denominator and the magnitude of the numerator. However, adults might prefer to rely on the magnitudes of the components and compare the magnitudes of the whole fractions only when the use of a componential strategy is made difficult.
Negative priming of unattended part primes: Implications for models of holistic and analytic processing in object recognition

The “hybrid” model of object recognition (Hummel, 2001) proposes that unattended objects are processed holistically, while attended objects are processed both holistically and analytically. Supporting evidence for this claim was reported by Thoma, Hummel, and Davidoff (2004) who showed that, unlike whole object primes, unattended split object parts (presumed to require analytic processing) do not elicit repetition priming. Here we tested the generality of this finding by contrasting priming for whole and part prime stimuli as a function of prime informativeness and by modifying the design so that both unattended whole and part prime displays contained a single perceptual object. Unlike Thoma et al. (2004) the results showed negative (rather than an absence of) priming for unattended half object primes. These findings place new constraints on theoretical models of the role of attention in object recognition.
Functional Assessment of TSC2 Variants Identified in Individuals with Tuberous Sclerosis Complex

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutations in the TSC1 or TSC2 genes. The TSC1 and TSC2 gene products, TSC1 and TSC2, form a complex that inhibits the mammalian target of rapamycin (mTOR) complex 1 (TORC1). Here, we investigate the effects of 78 TSC2 variants identified in individuals suspected of TSC, on the function of the TSC1–TSC2 complex. According to our functional assessment, 40 variants disrupted the TSC1–TSC2‐dependent inhibition of TORC1. We classified 34 of these as pathogenic, three as probably pathogenic and three as possibly pathogenic. In one case, a likely effect on splicing as well as an effect on function was noted. In 15 cases, our functional assessment did not agree with the predictions of the SIFT amino acid substitution analysis software. Our data support the notion that different, nonterminating TSC2 mutations can have distinct effects on TSC1–TSC2 function, and therefore, on TSC pathology.
Informational dynamics of vasomotion in microvascular networks: a review

Vasomotion refers to spontaneous oscillation of small vessels observed in many microvascular beds. It is an intrinsic phenomenon unrelated to cardiac rhythm or neural and hormonal regulation. Vasomotion is found to be particularly prominent under conditions of metabolic stress. In spite of a significant existent literature on vasomotion, its physiological and pathophysiological roles are not clear. It is thought that modulation of vasomotion by vasoactive substances released by metabolizing tissue plays a role in ensuring optimal delivery of nutrients to the tissue. Vasomotion rhythms exhibit a great variety of temporal patterns from regular oscillations to chaos. The nature of vasomotion rhythm is believed to be significant to its function, with chaotic vasomotion offering several physiological advantages over regular, periodic vasomotion. In this article, we emphasize that vasomotion is best understood as a network phenomenon. When there is a local metabolic demand in tissue, an ideal vascular response should extend beyond local microvasculature, with coordinated changes over multiple vascular segments. Mechanisms of information transfer over a vessel network have been discussed in the literature. The microvascular system may be regarded as a network of dynamic elements, interacting, either over the vascular anatomical network via gap junctions, or physiologically by exchange of vasoactive substances. Drawing analogies with spatiotemporal patterns in neuronal networks of central nervous system, we ask if properties like synchronization/desynchronization of vasomotors have special significance to microcirculation. Thus the contemporary literature throws up a novel view of microcirculation as a network that exhibits complex, spatiotemporal and informational dynamics.
Perceived health from biological motion predicts voting behaviour

Body motion signals socially relevant traits like the sex, age, and even the genetic quality of actors and may therefore facilitate various social judgements. By examining ratings and voting decisions based solely on body motion of political candidates, we considered how the candidates’ motion affected people's judgements and voting behaviour. In two experiments, participants viewed stick figure motion displays made from videos of politicians in public debate. Participants rated the motion displays for a variety of social traits and then indicated their vote preference. In both experiments, perceived physical health was the single best predictor of vote choice, and no two-factor model produced significant improvement. Notably, although attractiveness and leadership correlated with voting behaviour, neither provided additional explanatory power to a single-factor model of health alone. Our results demonstrate for the first time that motion can produce systematic vote preferences.
Clinical Analysis, Management and Outcome of Duane’s Retraction Syndrome at a Tertiary Eye Care Centre in South India

Materials & Methods: This prospective, interventional, non randomised study of 102 patients diagnosed with DRS was done from September 2009 to August 2011. Various characteristics studied included sex, age at presentation, laterality, manifest primary position horizontal deviation, upshoot and downshoot, amblyopia, and associated ocular and systemic abnormalities. Follow up for non surgical patients was for minimum period of 6 months. Surgery was advised in patients with anomalous head posture of more than 15 degrees, cosmetically unacceptable upshoot or downshoot, significant deviation in primary position and globe retraction. Post operative follow up of surgical cases was done at 1 month and were followed up for a minimum period of 6 months.
Destigmatising schizophrenia: does changing terminology reduce negative attitudes?

AIMS AND METHOD Health promotion campaigns using current terminology have had limited success in reducing stigma to schizophrenia. Terminology and subgroups based on historical precedent, clinical experience and psychosocial research have been developed to provide an alternative to existing terminology, and the attitudes to schizophrenia and alternative terminology of a sample of medical students ( n =241) were compared. RESULTS Overall attitudes were significantly less negative with the alternatives. The students were less negative about the potential for recovery in relation to all the subgroups than for schizophrenia. Concerns about dangerousness were also less prominent with the exception of the drug-related group. CLINICAL IMPLICATIONS Subgroups and alternative terminology should be further explored in programmes to destigmatise schizophrenia.

Significance of Methylprednisolone Therapy in Acute Spinal Cord Injury with Special Reference to Short-Term Follow-Up

受傷後24時間以内の脊髄外傷症例38例を対象として,受傷後2週間での神経学的な変化に注目し,MPSS大量療法の効果について検討した。 MPSS投与群16例,非投与群22例に対し,画像診断と神経学的徴候を考慮して外科的あるいは保存的治療の選択を行うとともに,MPSS投与群の症例にはNASCIS IIの方法に準じたMPSSの大量療法を実施した。 運動機能と知覚機能の評価はNASCIS IIの方法に準じて行い,両側14筋群に関する運動機能とC-2からS-5までの両側29髄節におけるピン痛覚,触覚に関する知覚機能を判定した。 その結果,運動機能に関しては,受傷後2週間時において,MPSS投与群16例中3例にスコア2点ないし6点の改善が認められ,悪化例はなかったのに対し,MPSS非投与群22例では改善例はなく,2例においてそれぞれスコア15点および20点の悪化がみられた。 知覚機能に関しても同様に,MPSS投与群でスコア1点ないし13点の間で5例に改善が認められ,悪化例はなかったのに対し,MPSS非投与群では,1例にスコア2点の改善が認められた一方,スコア1点ないし25点の間で5例に悪化がみられた。 両群におけるこれら神経学的所見の改善に関する差は有意であり,今回の検討の結果から,神経学的所見の悪化に対応すると考えられている二次的脊髄損傷を最小限に止める目的で,MPSSを受傷後可能な限り早期に大量に使用することは有用であることが示唆された。
Effects of hyperoxic ventilation on 6‐h survival at the critical haemoglobin concentration aggravated by experimentally induced tachycardia in anaesthetized pigs

Aim: Administration of 100% oxygen [hyperoxic ventilation (HV)] has been proven to ameliorate oxygen transport, tissue oxygenation and survival in different models of extreme normovolemic and hypovolemic anaemia. However, up to date, it is unknown whether HV is also able to improve outcome of extreme anaemia if myocardial oxygen consumption is contemporaneously increased by tachycardia. Therefore, we investigated the influence of HV on the 6‐h survival rate during extreme anaemia and aggravated by experimentally induced tachycardia in a prospective, randomized study in a pig model of critical anaemia.
The Influence of Sentential Position on Noun Phrase Structure Priming

This article explores the interaction between global sentence context and local syntactic decision making. Specifically, four noun phrase (NP) structural priming experiments investigated whether the position of an NP within a sentence increased speakers' tendency to repeat primed structure. We crossed the position of the NP with the structure of the NP, such that NPs could be sentence initial or final in prime sentences. We further manipulated whether the to-be-modified target NP was sentence initial or final. Structural persistence effects were consistently observed, but there was no influence of parallel position. Rather, sentence-initial NP primes had a stronger influence on subsequent syntactic decisions than sentence-final primes, suggesting a primacy effect. Sentence-initial target NPs contributed to this primacy effect, while sentence-final target NPs did not. We argue that this primacy effect arises as the result of greater processing demands and resources for early than for late sentence constituents as well as deeper encoding and more focused attention when processing the beginnings of sentences.
Sensitive Detection of KRAS Mutations Using Enhanced‐ice‐COLD‐PCR Mutation Enrichment and Direct Sequence Identification

A number of methods allowing the detection of low levels of KRAS mutations have been developed in the last years. However, although these methods have become increasingly sensitive, they can rarely identify the mutated base directly without prior knowledge on the mutated base and are often incompatible with a sequencing‐based read‐out desirable in clinical practice. Here, we present a modified version of the ice‐COLD‐PCR assay called Enhanced‐ice‐COLD‐PCR (E‐ice‐COLD‐PCR) for KRAS mutation detection and identification, which allows the enrichment of the six most frequent KRAS mutations. The method is based on a nonextendable chemically modified blocker sequence, complementary to the wild‐type (WT) sequence leading to the enrichment of mutated sequences. This assay permits the reliable detection of down to 0.1% mutated sequences in a WT background. A single genotyping assay of the amplification product by pyrosequencing directly following the E‐ice‐COLD‐PCR is performed to identify the mutated base. This developed two‐step method is rapid and cost‐effective, and requires only a small amount of starting material permitting the sensitive detection and sequence identification of KRAS mutations within 3 hr. This method is applied in the current study to clinical colorectal cancer samples and enables detection of mutations in samples, which appear as WT using standard detection technologies.
Eye movements reveal rapid concurrent access to factual and counterfactual interpretations of the world

Imagining a counterfactual world using conditionals (e.g., If Joanne had remembered her umbrella …) is common in everyday language. However, such utterances are likely to involve fairly complex reasoning processes to represent both the explicit hypothetical conjecture and its implied factual meaning. Online research into these mechanisms has so far been limited. The present paper describes two eye movement studies that investigated the time-course with which comprehenders can set up and access factual inferences based on a realistic counterfactual context. Adult participants were eye-tracked while they read short narratives, in which a context sentence set up a counterfactual world (If … then …), and a subsequent critical sentence described an event that was either consistent or inconsistent with the implied factual world. A factual consistent condition (Because … then …) was included as a baseline of normal contextual integration. Results showed that within a counterfactual scenario, readers quickly inferred the implied factual meaning of the discourse. However, initial processing of the critical word led to clear, but distinct, anomaly detection responses for both contextually inconsistent and consistent conditions. These results provide evidence that readers can rapidly make a factual inference from a preceding counterfactual context, despite maintaining access to both counterfactual and factual interpretations of events.
Regulation of cholesterol biosynthetic pathway in different regions of the rat central nervous system

In this study, we investigated the regulatory network of the key and rate‐limiting enzyme of cholesterol biosynthetic pathway, the 3‐hydroxy 3‐methylglutaryl coenzyme A reductase (HMGR) in different brain regions, to add new insight about lipid metabolism and physiology in the central nervous system (CNS).
Mutant TP53 Posttranslational Modifications: Challenges and Opportunities

The wild‐type (WT) human p53 (TP53) tumor suppressor can be posttranslationally modified at over 60 of its 393 residues. These modifications contribute to changes in TP53 stability and in its activity as a transcription factor in response to a wide variety of intrinsic and extrinsic stresses in part through regulation of protein–protein and protein–DNA interactions. The TP53 gene frequently is mutated in cancers, and in contrast to most other tumor suppressors, the mutations are mostly missense often resulting in the accumulation of mutant (MUT) protein, which may have novel or altered functions. Most MUT TP53s can be posttranslationally modified at the same residues as in WT TP53. Strikingly, however, codons for modified residues are rarely mutated in human tumors, suggesting that TP53 modifications are not essential for tumor suppression activity. Nevertheless, these modifications might alter MUT TP53 activity and contribute to a gain‐of‐function leading to increased metastasis and tumor progression. Furthermore, many of the signal transduction pathways that result in TP53 modifications are altered or disrupted in cancers. Understanding the signaling pathways that result in TP53 modification and the functions of these modifications in both WT TP53 and its many MUT forms may contribute to more effective cancer therapies.
Markedness effects in Norwegian–English bilinguals: Task-dependent use of language-specific letters and bigrams

This study investigates how bilinguals use sublexical language membership information to speed up their word recognition process in different task situations. Norwegian–English bilinguals performed a Norwegian–English language decision task, a mixed English lexical decision task, or a mixed Norwegian lexical decision task. The mixed lexical decision experiments included words from the nontarget language that required a “no” response. The language specificity of the Bokmål (a Norwegian written norm) and English (non)words was varied by including language-specific letters (“smør”, “hawk”) or bigrams (“dusj”, “veal”). Bilinguals were found to use both types of sublexical markedness to facilitate their decisions, language-specific letters leading to larger effects than language-specific bigrams. A cross-experimental comparison indicates that the use of sublexical language information was strategically dependent on the task at hand and that decisions were based on language membership information derived directly from sublexical (bigram) stimulus characteristics instead of indirectly via their lexical representations. Available models for bilingual word recognition fail to handle the observed marker effects, because all consider language membership as a lexical property only.
True and intentionally fabricated memories

The aim of the experiment reported here was to investigate the processes underlying the construction of truthful and deliberately fabricated memories. Properties of memories created to be intentionally false (fabricated memories) were compared to properties of memories believed to be true (true memories). Participants recalled and then wrote or spoke true memories and fabricated memories of everyday events. It was found that true memories were reliably more vivid than fabricated memories and were nearly always recalled from a first-person perspective. In contrast, fabricated differed from true memories in that they were judged to be reliably older, were more frequently recalled from a third-person perspective, and linguistic analysis revealed that they required more cognitive effort to generate. No notable differences were found across modality of reporting. Finally, it was found that intentionally fabricated memories were created by recalling and then “editing” true memories. Overall, these findings show that true and fabricated memories systematically differ, despite the fact that both are based on true memories.
Accelerative and decelerative effects of hedonic valence and emotional arousal during visual scene processing

Perceptual processing of natural scene pictures is enhanced when the scene conveys emotional content. Such “motivated attention” to pleasant and unpleasant pictures has been shown to improve identification accuracy in non-speeded behavioural tasks. An open question is whether emotional content also modulates the speed of visual scene processing. In the present studies we show that unpleasant content reliably slowed two-choice categorization of pictures, irrespective of physical image properties, perceptual complexity, and categorization instructions. Conversely, pleasant content did not slow or even accelerated choice reactions, relative to neutral scenes. As indicated by lateralized readiness potentials, these effects occurred at cognitive processing rather than motor preparation/execution stages. Specifically, analysis of event-related potentials showed a prolongation of early scene discrimination for stimuli perceived as emotionally arousing, regardless of valence, and reflected in delayed peaks of the N1 component. In contrast, the timing of other processing steps, reflected in the P2 and late positive potential components and presumably related to post-discriminatory processes such as stimulus–response mapping, appeared to be determined by hedonic valence, with more pleasant scenes eliciting faster processing. Consistent with this model, varying arousal (low/high) within the emotional categories mediated the effects of valence on choice reaction speed. Functionally, arousal may prolong stimulus analysis in order to prevent erroneous and potentially harmful decisions. Pleasantness may act as a safety signal allowing rapid initiation of overt responses.
Rapid communication: Mental time travel: Effects of trial duration on episodic and semantic content

Studies exploring mental time travel commonly use cue-word paradigms to elicit past and future autobiographical events. However, the effect of trial duration (how long participants are allowed to describe events) on the relationship between episodic and nonepisodic detail and episodic specificity (i.e., whether longer durations increase event specificity) has not been examined. To resolve these issues, a cue-word study was devised whereby participants described past and future events under three randomly administered time constraints: short (1-min), standard (3-min), and long (5-min) durations. Findings indicated that an individual's capacity for episodic and nonepisodic thought for the past and future were unrelated. This lends supports to the idea that independent mechanisms are responsible for episodic and semantic information. This study also offers clarity concerning the effect of different trial durations on episodic specificity, which may aid the design of future studies of mental time travel.
Gain‐of‐Function Mutation in STIM1 (P.R304W) Is Associated with Stormorken Syndrome

Stormorken syndrome is a rare autosomal dominant disorder characterized by a phenotype that includes miosis, thrombocytopenia/thrombocytopathy with bleeding time diathesis, intellectual disability, mild hypocalcemia, muscle fatigue, asplenia, and ichthyosis. Using targeted sequencing and whole‐exome sequencing, we identified the c.910C > T transition in a STIM1 allele (p.R304W) only in patients and not in their unaffected family members. STIM1 encodes stromal interaction molecule 1 protein (STIM1), which is a finely tuned endoplasmic reticulum Ca2+ sensor. The effect of the mutation on the structure of STIM1 was investigated by molecular modeling, and its effect on function was explored by calcium imaging experiments. Results obtained from calcium imaging experiments using transfected cells together with fibroblasts from one patient are in agreement with impairment of calcium homeostasis. We show that the STIM1 p.R304W variant may affect the conformation of the inhibitory helix and unlock the inhibitory state of STIM1. The p.R304W mutation causes a gain of function effect associated with an increase in both resting Ca2+ levels and store‐operated calcium entry. Our study provides evidence that Stormorken syndrome may result from a single‐gene defect, which is consistent with Mendelian‐dominant inheritance.
