Amrisha Vaish, Robert Hepach, Tobias Grossmann
'Much research has investigated children's understanding of others' mental states in terms of beliefs, but far less is known about their understanding of others' desires. To fill this gap, we used an eye-tracking paradigm to test 2-year-old children's desire understanding by measuring their anticipatory looking behavior as well as changes in their internal arousal (i.e., changes in pupil dilation). Children showed increased pupil dilation when an adult reached for an object she had previously emoted negatively towards (the object incongruent with her desire)...

OBJECTIVES: This study aimed to analyse if children with untreated or treated caries (restorations/missing teeth) are perceived differently compared to children with healthy teeth and to explore possible differences in the perception by laypersons and dental experts. METHODS: Eye movements of female experts (n = 20) and laypersons (n = 18) were recorded by eye-tracking while paired images (neutral expression/teeth not visible; emotional expression/smiling, teeth visible) of children with healthy teeth, with visible untreated or treated caries (restorations/missing teeth as a consequence of caries treatment), each n = 13, were presented...

OBJECTIVE: The objective of the current study was to determine the frequency and severity of symptoms of posttraumatic stress disorder (PTSD) in journalists covering conflict. METHODS: PTSD data (Impact of Event Scale-Revised) collected over an 18-year period from 684 conflict journalists were analyzed retrospectively for frequency and severity of reexperiencing, avoidance, and arousal symptoms. Conflicts covered were civil wars in the Balkans ( n = 140 journalists), 9/11 attack in New York City ( n = 46), Iraq war ( n = 84), Mexico drug wars ( n = 104), civil war in Syria ( n = 59), Kenya election violence/Al-Shabab terror ( n = 57), state-sanctioned media intimidation in Iran ( n = 114), and the current migration crisis in Europe ( n = 80)...

BACKGROUND: Vigilance is generally understood as the ability to detect infrequent critical events through long time periods. In tasks like the Sustained Attention to Response Task (SART), participants tend to detect fewer events across time, a phenomenon known as "vigilance decrement". However, vigilance might also involve sustaining a tonic arousal level. In the Psychomotor Vigilance Test (PVT), the vigilance decrement corresponds to an increment across time in both mean and variability of reaction time...

Chronic pain may alter both affect- and value-related behaviors, which represents a potentially treatable aspect of chronic pain experience. Current understanding of how chronic pain influences the function of brain reward systems, however, is limited. Using a monetary incentive delay task and functional magnetic resonance imaging (fMRI), we measured neural correlates of reward anticipation and outcomes in female participants with the chronic pain condition of fibromyalgia (N = 17) and age-matched, pain-free, female controls (N = 15)...

Postoperative pain remains a complex problem that is difficult to manage in the clinical context, seriously affecting rehabilitation and the quality of life of patients after surgery. Nociceptors, of which the cell bodies are located in the dorsal root ganglion (DRG), are crucial for initiating and conducting the pain signal. The peripheral voltage-gated sodium channels, including Nav1.7, which is mainly expressed in the DRG, are key to understanding the mechanism underlying postoperative pain. Nav1.7, in particular, of which mutations in the encoding gene (SCN9A) can determine whether pain occurs, has aroused most attention...

Necrotising Sialometaplasia is a benign self limiting reactive condition of major and minor salivary glands, which can arouse suspicion for malignancy, clinically and histopathologically. Here, we report a case of 38-year-old female with a painful ulcer on the palate. The case enlightens the importance of clinicopathologic correlation and diligent follow up in diagnosis and management of the case.

The ability to recognize novel situations is among the most fascinating and vital of the brain functions. A hypothesis posits that encoding of novelty is prompted by failures in expectancy, according to computation matching incoming information with stored events. Thus, unexpected changes in context are detected within the hippocampus and transferred to downstream structures, eliciting the arousal of the dopamine system. Nevertheless, the precise locus of detection is a matter of debate. The dorsal CA1 hippocampus (dCA1) appears as an ideal candidate for operating a mismatch computation and discriminating the occurrence of diverse stimuli within the same environment...

The long history of poetry and the arts, as well as recent empirical results suggest that the way a word sounds (e.g., soft vs. harsh) can convey affective information related to emotional responses (e.g., pleasantness vs. harshness). However, the neural correlates of the affective potential of the sound of words remain unknown. In an fMRI study involving passive listening, we focused on the affective dimension of arousal and presented words organized in two discrete groups of sublexical (i.e., sound) arousal (high vs...

Accumulating evidence implicates gut microbiota as promising targets for the treatment of type 2 diabetes mellitus (T2DM). With a randomized clinical trial, we tested the hypothesis that alteration of gut microbiota may be involved in the alleviation of T2DM with hyperlipidemia by metformin and a specifically designed herbal formula (AMC). Four hundred fifty patients with T2DM and hyperlipidemia were randomly assigned to either the metformin- or AMC-treated group. After 12 weeks of treatment, 100 patients were randomly selected from each group and assessed for clinical improvement...

PURPOSE: Childhood absence epilepsy (CAE) is an epileptic syndrome presenting between 2nd-10th years. The spells are elicited with hyperventilation (HV) while sleep seems to exacerbate the electrical activity. Our aim is to describe sleep architecture and its relationship with epileptic discharges (EDs) in patients with CAE, before treatment and one year later. METHODS: Twenty-eight, drug-naive children were recruited (21 girls), mean age 90.1 ± 32.6 months...

Although numerous studies have investigated emotion regulation, the physiological responses and neural substrates of positive emotion regulation remain unclear. To address this question, we explored the effect of reappraisal on subjective experience, zygomatic electromyography (zEMG) response, and blood oxygen level response, using the same materials across three independent experiments. Behaviorally, up-regulating positive emotion increased the valence, arousal, and zEMG response, whereas down-regulating positive emotion decreased the valence, but not arousal or the zEMG response...

Spontaneous urea dissociation in water solution is a prominent source of protein carbamylation in our body. Protein carbamylation is a well-known phenomenon since early seventies. Some years ago, much interest in the diagnostic power of carbamylated protein arouse. Recently the target of the researches focused on its potential cardiovascular pathogenicity. Some authors claimed that this could be a reason for higher cardiovascular mortality in uremic patients. Nutritional therapy, amino acids supplementation and intensive dialysis regimen are some of the therapeutic tools tested to lower the carbamylation burst in this population...

Millions of individuals routinely remain awake for more than 18 h daily, which causes performance decrements. It is unknown if these functional impairments are the result of that extended wakefulness or from the associated shortened sleep durations. We therefore examined changes in objective reaction time performance and subjective alertness in a 32-d inpatient protocol in which participants were scheduled to wakefulness durations below 16 h while on a 20-h "day," with randomization into standard sleep:wake ratio (1:2) or chronic sleep restriction (CSR) ratio (1:3...

Currently, there is renewed interest in attempting to recruit the host immune system to eliminate cancers, and within this renewed activity, MUC1 continues to arouse interest. MUC1 has been considered a possible therapeutic target for the past 30 years as it is up-regulated, aberrantly glycosylated and its polarization is lost in many adenocarcinomas. Moreover, MUC1 is expressed by some haematopoietic cancers, including acute myeloid leukaemia and myeloma. Although multiple clinical trials have been initiated and immune responses have been documented, effective clinical benefit worthy of approval for general application has not as yet been achieved...

Noninvasive, objective quantitative techniques to gauge emotional states are fundamental for clinical psychology as they overcome subjective bias of currently used questionnaires. To this end, we investigated brain oscillatory EEG activity during caresslike, affective haptic elicitation conveyed on the forearm at two force (strength of the caress) and three velocity (velocity of the caress) levels. Thirty-two healthy subjects (16 female) were asked to assess each haptic stimulus in terms of arousal (i.e., intensity of emotional perception) and valence (i...

It has been assumed that β-endorphin, belonging to the family of opiodergic neuropeptides, might facilitate the inhibition of the male sexual response; however, its role in the control of the penile erectile tissue remains to be elucidated. This study aimed to evaluate in healthy men the course of β-endorphin in the systemic and cavernous blood through different stages of sexual arousal. Thirty-four (34) men were exposed to erotic stimuli to induce penile tumescence and rigidity. Blood was aspirated from the corpus cavernosum and a cubital vein during the penile conditions flaccidity, tumescence, rigidity and detumescence...
