Ya Wang, Yi Wang, Qing Zhao, Ji-Fang Cui, Xiao-Hong Hong, Raymond Ck Chan
This study explored specificity and visual perspective of mental time travel in schizophrenia. Fifteen patients with schizophrenia and 18 controls were recruited. Participants were asked to recall or imagine specific events according to cue words. Results showed that schizophrenia patients generated fewer specific events than controls, the recalled events were more specific than imagined events. Schizophrenia adopted less field perspective and more observer perspective than controls. These results suggested that patients with schizophrenia were impaired in mental time travel both in specificity and visual perspective...

OBJECTIVES: Psychological biases can distort treatment decision-making. The availability heuristic is one such bias, wherein events that are recent, vivid or easily imagined are readily 'available' to memory and are therefore judged more likely to occur than expected based on epidemiological data. We assessed if the occurrence of a serious colonoscopy complication for a primary care physician's patient influenced colonoscopy rates for the physician's other patients. DESIGN: Longitudinal study with time-varying exposure variables...

Recent studies indicate high levels of psychotic experiences in the general population. Here, we report a functional imaging study with 8 mentally healthy spiritual mediums and 8 matched controls. The mediums entered a mediumistic-trance state using a standardized manner by closing their eyes and actively seeking to ignore external and internal stimuli to achieve a 'state of emptiness'; in a control condition, they were instructed to re-enact the same mediumistic experience that they had during the mediumistic-trance condition but in a non-trance state (imaginative-trance)...

Recent neurophysiological and behavioral research suggests perception-action systems are tightly coupled. Accordingly, Fitts' law has been observed when individuals execute, perceive, and imagine actions. Developmental research has found that (a) children demonstrate Fitts' law in imagined actions and (b) imagined movement time (MT) becomes closer to actual MT as age increases. However, action execution, imagination, and perception have yet to be assessed together in children. The authors investigated how imagined and perceived MTs related to actual MTs in children and adolescents...

Alfred M Sadler, Ann Davis
The history of how PAs in the United States were first granted practice authority under the medical practice acts of the various states and territories begins in the 1960s with an imaginative way to circumvent the moratorium on licensure of new healthcare occupations in place at the time, while allowing the requisite flexibility for the new profession to take hold and thrive. In the subsequent decades, separate licensure for PAs was required and adopted. Despite the enormous success of the PA profession over its first 50 years, challenges remain...

REVIEW

Philosophical aesthetics is the branch of philosophy which explores issues having to do with art, beauty, and related phenomena. Philosophers have often been skeptical about the place of empirical investigation in aesthetics. However, in recent years many philosophical aestheticians have turned to cognitive science to enrich their understanding of their subject matter. Cognitive scientists have, in turn, been inspired by work in philosophical aesthetics. This essay focuses on a representative subset of the areas in which there has been fruitful dialog between philosophical aestheticians and cognitive scientists...

Woogul Lee, Johnmarshall Reeve
Intrinsic motivation is the inherent tendency to seek out novelty and challenge, to explore and investigate, and to stretch and extend one's capacities. When people imagine performing intrinsically motivating tasks, they show heightened anterior insular cortex (AIC) activity. To fully explain the neural system of intrinsic motivation, however, requires assessing neural activity while people actually perform intrinsically motivating tasks (i.e., while answering curiosity-inducing questions or solving competence-enabling anagrams)...

BACKGROUND: Bioinformatics has multitudinous identities, organisational alignments and disciplinary links. This variety allows bioinformaticians and bioinformatic work to contribute to much (if not most) of life science research in profound ways. The multitude of bioinformatic work also translates into a multitude of credit-distribution arrangements, apparently dismissing that work. RESULTS: We report on the epistemic and social arrangements that characterise the relationship between bioinformatics and life science...

The photonegative response to light stimulation in Rhodnius prolixus (Reduviidae, Triatominae) is modulated by compound eyes and ocelli. Screening pigments in the visual system have been shown to protect the cellular structures from the oxidative stress damage produced by blood ingestion and light stimulation. Red-eyed mutants of Rhodnius prolixus lack screening pigments in their compound eyes and ocelli and are exposed to more oxidative stress. Experiments with Rhodnius prolixus and Triatoma infestans red-eyed mutants reared from the first nymphal stage show damage in the retinas of the compound eyes and a decrease in photonegative responses due to light stimulation...

Mayflies (Ephemeroptera) display many primitive characters and a unique type of metamorphosis (Prometabola). However, information on the genomes and transcriptomes of this insect group is limited. The RNA sequencing study presented here generated the first de novo transcriptome assembly of Cloeon viridulum (Ephemeroptera: Baetidae), and compared gene expression signatures among the young larva (YL), mature larva (ML), subimago (SI), and imago (IM) stages of this mayfly. The transcriptome, based on 88 Gb of sequence data, comprised a set of 81,185 high quality transcripts...

The main goal of intensive care medicine is helping patients survive acute threats to their lives, while preserving and restoring life quality. Because of medical advancements, it is now possible to sustain life to an extent that would previously have been difficult to imagine. However, the goals of medicine are not to preserve organ function or physiological activity but to treat and improve the health of a person as a whole. When dealing with medical futilities, physicians and other members of the care team should be aware of some ethical principles...

Although autobiographical memory and episodic simulations recruit similar core brain regions, episodic simulations engage additional neural recruitment in the frontoparietal control network due to greater demands on constructive processes. However, previous functional neuroimaging studies showing differences in remembering and episodic simulation have focused on veridical retrieval of past experiences, and thus have not fully considered how retrieving the past in different ways from how it was originally experienced may also place similar demands on constructive processes...

Sandro Spinsanti
The many adjectives usually used to explain the desirable death - painless, decent, human… - do not include the term "graceful". However, this is a way that can be explored, too, if you imagine to die in the Three Graces' arms, namely in a mood that, according to Ugo Foscolo, is "between the exaggerated cheerfulness and the deep pain". The pathway turns out to be much more productive if we allow ourselves to be led by the original names of the Three Graces and by their symbology. Euphrosyne suggests the wisdom through which the mind guides our choices, especially those that show as palliative cures; Aglaea suggests the peace linked to the possibility to keep the death process under control; Talia lets us imagine a death seen as growth, as a pathway that ends at the peak of our own humanity...

S Walter Englander, Leland Mayne
We consider the differences between the many-pathway protein folding model derived from theoretical energy landscape considerations and the defined-pathway model derived from experiment. A basic tenet of the energy landscape model is that proteins fold through many heterogeneous pathways by way of amino acid-level dynamics biased toward selecting native-like interactions. The many pathways imagined in the model are not observed in the structure-formation stage of folding by experiments that would have found them, but they have now been detected and characterized for one protein in the initial prenucleation stage...

When supervising a medical student or a doctor in training, it is useful to know the different stages of clinical reasoning in order to identify at what stage the learner encounters a difficulty in making the right decision. Is he having trouble characterizing the clinical problem ? Is he generating the right hypotheses that are adapted to the data collection ? Is it a problem of verification of assumptions ? Of interpreting the data ? Of presumptive diagnosis or a poor choice of an intervention plan ? By making a pedagogical diagnosis, the supervisor will be more effective in adapting his recommendations in a more targeted way to the specific difficulties of the student or young colleague...

Optical microresonators confine light to a particular microscale trajectory, are exquisitely sensitive to their microenvironment, and offer convenient readout of their optical properties. Taken together, this is an immensely attractive combination that makes optical microresonators highly effective as sensors and transducers. Meanwhile, advances in material science, fabrication techniques, and photonic sensing strategies endow optical microresonators with new functionalities, unique transduction mechanisms, and in some cases, unparalleled sensitivities...

AIM: "Don't put me in a home" is a common preference of older people, but so too is "I don't want to be a burden on my family." These and other goals often conflict with each other when people have worsening dementia and the issue of possible nursing home admission arises. METHODS: Community-dwelling older hospital patients were asked to imagine that they lived alone, had dementia and were experiencing increasing practical difficulties, and were presented with 11 possible "outcome packages...

BACKGROUND: The incidence of post-discharge nausea and vomiting (PDNV) after ambulatory anaesthesia using total intravenous anaesthesia with a risk-stratified anti-emetic approach is not well documented in the literature. In this study, we outline such an approach. The goal was to achieve an acceptably low rate of PDNV both immediately and the day after surgery. METHODS: With ethics committee approval, adult patients undergoing outpatient surgery received a Propofol-based general anaesthetic plus standardised PONV-prophylaxis corresponding to their Apfel risk-score (0-4); ondansetron (risk-score 2), additional dexamethasone (risk-score 3), and additional droperidol (risk-score 4)...

Although women who highly identify with other women are more susceptible to stereotype threat effects, women's identification might associate with greater leadership aspirations contingent on (1) counter-stereotype salience and (2) feminist identification. When gender counter-stereotypes are salient, women's identification should associate with greater leadership aspiration regardless of feminism, while when gender stereotypes are salient, women's identification would predict greater leadership aspirations contingent on a high level of feminist identification...
