    少汗症外胚层发育不良(HED)是一种影响外胚层起源结构的遗传性疾病,比如牙齿,头发,和汗腺。与常染色体隐性和显性遗传方式相比,X-连锁HED(XLHED)的特点是缺牙症/少牙症,没有/稀疏的头发,多汗症/多汗症,和特征性的面部特征,是最常见的,其主要原因是外生体异常蛋白A(EDA)基因的突变。本研究旨在阐述中国男性XLHED的临床和分子特征,并总结和比较先前的一些发现。
    基因组DNA是从先证者及其家庭成员的外周血中获得的,然后使用Sanger测序进行EDA的突变分析。采用实时定量PCR和Western印迹法检测EDA的表达。使用荧光素酶测定法检测NF-κB的转录活性。
    具有XLHED的先证者被鉴定为新的EDA突变,c.1119G>C(p。M373I),影响了跨膜蛋白外显子8突变的分子分析,继承自母亲。他表现出严重的多颗牙齿脱落,缺少20多颗恒牙,头发和眉毛稀疏,干,薄,皮肤瘙痒。此外,他的出汗功能在一定程度上是异常的。
    功能研究表明,这种新型突变体导致NF-κB的EDA表达水平和转录活性显着降低。我们的发现扩展了XLHED患者中EDA突变的范围,为进一步探讨XLHED的发病机制提供了依据和思路。
    UNASSIGNED: Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder that influences structures of ectodermal origin, such as teeth, hair, and sweat glands. Compared with autosomal recessive and dominant modes of inheritance, the X-linked HED (XLHED) characterized by Hypodontia/Oligodontia teeth, Absent/sparse hair, Anhidrosis/hypohidrosis, and characteristic facial features, is the most frequent and its primary cause is the mutation of ectodysplasin A (EDA) gene. This research aimed to expound the clinical and molecular features of a Chinese male with XLHED and to summarize and compare several previous findings.
    UNASSIGNED: Genomic DNA was obtained from the peripheral blood of the proband and his family members, then Sanger sequencing was used to perform a mutational analysis of EDA. Real-time quantitative PCR and Western blotting were used to detect EDA expression. The transcriptional activity of NF-κB was detected using a luciferase assay.
    UNASSIGNED: The probandwith XLHED was identified a novel EDA mutation, c.1119G>C(p.M373I), that affected the molecular analysis of transmembrane protein exon8 mutations, inherited from the mother. He showed a severe multiple-tooth loss, with over 20 permanent teeth missing and sparse hair and eyebrows, dry, thin, and itching skin. Furthermore, his sweating function was abnormal to a certain extent.
    UNASSIGNED: The functional study showed that this novel mutant led to a significant decrease in the EDA expression level and transcriptional activity of NF-κB. Our findings extend the range of EDA mutations in XLHED patients, which provides the basis and idea for further exploring the pathogenesis of XLHED.

    This data paper presents a unique multimodal dataset collected from a comprehensive experiment using a wheelchair training simulator. The dataset consists of quantitative and qualitative data that represents the user\'s experience and performance. Participants engaged in a series of navigational tasks in a simulated environment under two distinct system configuration conditions: a. a conventional monitor display and b. a virtual reality (VR) headset. The monitor group has a total of 24 participants data while using the simulator with a standard display and then other two groups of 18 and 16 respectively using the VR headset with a different wheelchair\'s speed profile. It was collected data from total of 58 participants. The dataset includes physiological data - Heart Rate Variability (HRV), Electrodermal Activity (EDA), Acceleration (ACC), Skin Temperature, Heart Rate (HR), and Blood Volume Pulse (BVP) - collected during both experiments. Additionally, for the standard display condition, more detailed data comprising Electroencephalography (EEG) and eye-tracking metrics were recorded to provide insights into cognitive load and visual attention patterns. System metrics captured from the simulator provide an objective performance report, including task completion times, error rates (collision of the virtual wheelchair), number of joystick commands. Also, the navigation efficiency data is complemented by post-experiment questionnaires, which gathered subjective responses on user experience, perceived difficulty, the user immersive levels, arousal, and simulator sickness symptoms. This dataset is valuable for researchers and practitioners in the fields of assistive technology, human-computer interaction, and rehabilitation. It offers metrics to a comprehensive view of how different display technologies influence the user experience in wheelchair simulation training. The data allows for in-depth analysis of physiological responses, cognitive engagement, and subjective perceptions, providing a foundation for future research on effective wheelchair training methodologies and the potential benefits of VR in rehabilitation settings.

    目标:尽管有令人震惊的证据表明对妇女的性暴力,人们对男性对强奸的情绪反应以及这些可能如何参与性暴力动态知之甚少。因此,我们的目的是捕捉如何在情感上评估强奸场景。方法:本研究评估了男性(N=30)的自我报告和心理生理情绪反应(面部肌电图,皮肤电活动)到强奸现场,并将其与他们对描绘非性暴力和非暴力男女互动的刺激的反应进行了对比。男人的情绪反应和他们对强奸神话的认可之间的联系,个性,还检查了性特征。结果:研究结果表明,强奸现场导致更高的负面影响,主观上和通过增加的面部肌电图(瓦楞纸板活动)索引,比其他两个刺激。此外,神经质的人格特质,较低的宜人性,较低的意识,精神病倾向,以及较低的性抑制倾向,都与强奸的主观性唤起有关。结论:研究结果增加了有关推定情感过程的文献,这些情感过程是对妇女的性暴力评估的基础。
    Objective: Despite alarming evidence on sexual violence against women, little is known about men\'s emotional responses to rape and how these may be involved in sexual violence dynamics. Accordingly, our aim was to capture how rape scenarios are emotionally appraised. Methods: The current study evaluated men\'s (N = 30) self-reported and psychophysiological emotional responses (facial EMG, electrodermal activity) to a rape scene, and contrasted it with their responses to stimuli depicting nonsexual violence and nonviolent male-female interactions. The associations between men\'s emotional responses and their endorsement of rape myths, personality, and sexual traits were also examined. Results: Findings revealed that the rape scene resulted in higher negative affect, both subjectively and indexed by increased facial EMG (corrugator activity), than the other two stimuli. Additionally, personality traits of neuroticism, lower agreeableness, lower consciousness, psychopathic tendencies, as well as lower sexual inhibition proneness, were all associated with higher subjective sexual arousal toward rape. Conclusions: Findings add to the literature on the putative emotional processes underpinning the appraisal of sexual violence against women.

    催眠,一种历史悠久的治疗方法,在解决一系列心理和躯体疾病方面的有效性已获得广泛认可。虽然它的主要作用是由自上而下的中央机制介导的,催眠还通过调节自主神经系统(ANS)发挥外周影响。心理生理措施,如心率(HR)及其变异性(HRV),皮肤电活动(EDA),呼吸频率(RR),和镇痛伤害性指数(ANI),作为ANS活性的可靠指标。研究一直证明催眠能力显着影响ANS功能,降低交感神经活动,增强副交感神经张力。这种效果在放松过程中特别明显,并且受到催眠能力和任务条件等中介因素的影响。尽管方法上有局限性,这篇综述强调了通过催眠增强ANS调制的潜力,包括它与中枢神经系统(CNS)的连接,优化与ANS功能障碍相关的心身疾病患者的治疗结果。
    Hypnosis, a time-honored therapeutic approach, has gained widespread recognition for its effectiveness in addressing a range of psychological and somatic disorders. While its primary effects are mediated by central top-down mechanisms, hypnosis also exerts peripheral influence by modulating the autonomic nervous system (ANS). Psychophysiological measures, such as heart rate (HR) and its variability (HRV), electrodermal activity (EDA), respiratory rate (RR), and the analgesia nociceptive index (ANI), serve as reliable indicators of ANS activity. Studies have consistently demonstrated hypnosis\' ability to significantly impact ANS functions, lowering sympathetic activity and enhancing parasympathetic tone. This effect is particularly pronounced during relaxation procedures and is influenced by mediating factors like hypnotizability and task conditions. Despite methodological limitations, this review highlights the potential of enhanced ANS modulation through hypnosis, including its connections to the central nervous system (CNS), to optimize therapeutic outcomes in patients with psychosomatic disorders associated with ANS dysfunction.

    虚拟现实暴露疗法是一种认知行为疗法的方法,通过使疗法切实可行和具有成本效益来帮助治疗焦虑症。它还允许通过使用客观,持续的反馈。这种反馈可以使用生物传感器来获得,以收集生理信息,例如心率,皮肤电活动和额叶大脑活动。作为开发我们客观反馈框架的一部分,我们开发了一个虚拟现实适应完善的情感Stroop颜色字任务。我们使用这种适应来区分三种不同的焦虑水平:没有焦虑,轻度焦虑和严重焦虑。我们对年龄在18至65岁之间的29名参与者进行了环境测试。在分析和验证此环境之后,我们使用它创建了一个数据集,用于对指定的焦虑水平进行进一步的机器学习分类.要实时应用这些信息,我们所有的信息都是在虚拟现实中处理的。我们的卷积神经网络能够使用留一交叉验证以75%的准确率区分焦虑水平。这表明我们的系统可以准确区分不同的焦虑水平。
    Virtual Reality Exposure Therapy is a method of cognitive behavioural therapy that aids in the treatment of anxiety disorders by making therapy practical and cost-efficient. It also allows for the seamless tailoring of the therapy by using objective, continuous feedback. This feedback can be obtained using biosensors to collect physiological information such as heart rate, electrodermal activity and frontal brain activity. As part of developing our objective feedback framework, we developed a Virtual Reality adaptation of the well-established emotional Stroop Colour-Word Task. We used this adaptation to differentiate three distinct levels of anxiety: no anxiety, mild anxiety and severe anxiety. We tested our environment on twenty-nine participants between the ages of eighteen and sixty-five. After analysing and validating this environment, we used it to create a dataset for further machine-learning classification of the assigned anxiety levels. To apply this information in real-time, all of our information was processed within Virtual Reality. Our Convolutional Neural Network was able to differentiate the anxiety levels with a 75% accuracy using leave-one-out cross-validation. This shows that our system can accurately differentiate between different anxiety levels.

    评估驾驶员的心理工作量对于减少道路交通事故至关重要。这项研究在模拟的基于听觉的双任务驾驶场景中检查了驾驶员的心理工作量,以驾驶任务为主要任务,和基于听觉的N-back任务作为次要任务。总共三个级别的精神工作量(即,低,中等,高)是通过改变次要任务的难度水平来操纵的(即,没有次要任务的存在,1-back,2后卫)。多式联运措施,包括一套主观措施,生理措施,和行为绩效指标,是在实验过程中收集的。结果表明,任务难度的增加导致脑力劳动的主观评分增加,而次要N-back任务的任务性能下降。在多模式生理测量中,不同程度的脑力负荷之间存在显着差异,比如EEG信号中的delta波,眼球运动信号中的固定距离,ECG信号中的时域和频域测量,和EDA信号中的皮肤电导。此外,与车辆速度以及踏板输入和车辆位置偏差有关的四项驾驶性能测量也显示出对驾驶员心理工作量变化的敏感性。这项研究的发现有助于全面了解驾驶场景中心理工作量评估的有效措施,并有助于开发智能驾驶系统以准确识别驾驶员的精神状态。
    Assessing drivers\' mental workload is crucial for reducing road accidents. This study examined drivers\' mental workload in a simulated auditory-based dual-task driving scenario, with driving tasks as the main task, and auditory-based N-back tasks as the secondary task. A total of three levels of mental workload (i.e., low, medium, high) were manipulated by varying the difficulty levels of the secondary task (i.e., no presence of secondary task, 1-back, 2-back). Multimodal measures, including a set of subjective measures, physiological measures, and behavioral performance measures, were collected during the experiment. The results showed that an increase in task difficulty led to increased subjective ratings of mental workload and a decrease in task performance for the secondary N-back tasks. Significant differences were observed across the different levels of mental workload in multimodal physiological measures, such as delta waves in EEG signals, fixation distance in eye movement signals, time- and frequency-domain measures in ECG signals, and skin conductance in EDA signals. In addition, four driving performance measures related to vehicle velocity and the deviation of pedal input and vehicle position also showed sensitivity to the changes in drivers\' mental workload. The findings from this study can contribute to a comprehensive understanding of effective measures for mental workload assessment in driving scenarios and to the development of smart driving systems for the accurate recognition of drivers\' mental states.

    背景:这项研究的目的是分析一对少汗性外胚层发育不良(HED)兄弟之间牙齿缺失表型的差异,并通过比较突变的基因位点通过全外显子组测序研究兄弟之间的潜在机制。
    方法:收集患者及其母亲的临床资料,从外周血样本中提取基因组DNA。通过全外显子组测序,筛选出次要等位基因频率(MAF)≤0.05的非同义单核苷酸变异和先前与牙齿发育不全相关的基因的插入/缺失变异,和变异被认为是潜在的致病性通过SIFT评估,Polyphen-2、CADD和ACMG。进行Sanger测序以检测基因变异。通过PsiPred4.0和AlphaFold2预测突变蛋白的二级和三级结构。
    结果:两兄弟均被临床诊断为HED,但是弟弟的牙齿比哥哥多。在两个兄弟中都鉴定了EDA变异(c.878T>G)。此外,在哥哥中鉴定出WNT10A的复合杂合变异(c.511C>T和c.637G>A)。先前未报道同一患者中EDA(c.878T>G)和WNT10A(c.511C>T和c.637G>A)的双基因变异。与野生型蛋白相比,变体WNT10A蛋白的二级结构显示出α-螺旋和β-折叠的数量和位置的变化。WNT10A变体的三级结构和分子模拟对接表明,WNT10A与FZD5结合的位点和方向发生了变化。
    结论:复合杂合WNT10A错义变异可能会加剧EDA变异引起的HED缺失牙齿数量。
    BACKGROUND: The aim of this study was to analyse the differences in the phenotypes of missing teeth between a pair of brothers with hypohidrotic ectodermal dysplasia (HED) and to investigate the underlying mechanism by comparing the mutated gene loci between the brothers with whole-exome sequencing.
    METHODS: The clinical data of the patients and their mother were collected, and genomic DNA was extracted from peripheral blood samples. By Whole-exome sequencing filtered for a minor allele frequency (MAF) ≤0.05 non-synonymous single-nucleotide variations and insertions/deletions variations in genes previously associated with tooth agenesis, and variations considered as potentially pathogenic were assessed by SIFT, Polyphen-2, CADD and ACMG. Sanger sequencing was performed to detect gene variations. The secondary and tertiary structures of the mutated proteins were predicted by PsiPred 4.0 and AlphaFold 2.
    RESULTS: Both brothers were clinically diagnosed with HED, but the younger brother had more teeth than the elder brother. An EDA variation (c.878 T > G) was identified in both brothers. Additionally, compound heterozygous variations of WNT10A (c.511C > T and c.637G > A) were identified in the elder brother. Digenic variations in EDA (c.878 T > G) and WNT10A (c.511C > T and c.637G > A) in the same patient have not been reported previously. The secondary structure of the variant WNT10A protein showed changes in the number and position of α-helices and β-folds compared to the wild-type protein. The tertiary structure of the WNT10A variant and molecular simulation docking showed that the site and direction where WNT10A binds to FZD5 was changed.
    CONCLUSIONS: Compound heterozygous WNT10A missense variations may exacerbate the number of missing teeth in HED caused by EDA variation.

    具有精神病性格特征的人通常被认为在处理和体验情绪方面有困难。这些困难也可能转化为情绪激动的社会情况,例如社会排斥。被社会排斥通常被认为是压力和不愉快的,甚至可能导致自私或攻击性行为,这两者都与精神病的某些方面有关。当前的研究调查了在精心选择的社区样本中,对网络球范式中对社会排斥的自我报告和生理反应,这些个体在主要(N=24)或次要精神病特征(N=17)上得分较高。在整个样本中,网络球范式减少了欢乐和接近动机的体验,增加主观愤怒报告,并引起心率的变化。相比之下,在次级精神病特征上得分高的个体(以自我为中心的冲动性组)在长期社会排斥的习惯阶段表现出比在初级精神病特征上得分高的个体(无所畏惧的优势组)更强的生理反应,以皮肤电导水平的变化为索引。此外,自我报告和生理唤醒之间的潜在不匹配似乎仅在具有高度继发性精神病特征的个体中观察到。总的来说,目前的研究结果表明,当比较功能良好且具有不同精神病特征的个体时,在社会排斥情况下,情绪处理和调节的模式存在差异.似乎具有主要精神病特征的个人对上下文社会线索不敏感,而次要精神病特征高的个体则更受潜在威胁的社会状况的影响。谨慎地将目前的发现转移到法医样本中,他们支持从对精神病结构的行为理解转变为具有不同认知和情绪处理模式的更临床的观点,这些个体在主要或次要精神病特征上都很高。
    Individuals with psychopathic personality traits are generally thought to have difficulties in processing and experiencing emotions. These difficulties could also translate to emotionally charged social situations such as social exclusion. Being socially excluded is often experienced as stressful and unpleasant, potentially even leading to selfish or aggressive behavior-both of which are linked to certain aspects of psychopathy. The current study investigated self-report and physiological responses to social exclusion in the cyberball paradigm in a carefully selected community sample of individuals either scoring high on primary (N = 24) or secondary psychopathy traits (N = 17). Across the sample, the cyberball paradigm decreased experiences of joy and approach motivation, increased subjective anger reports, and induced changes in heart rate. In contrast, individuals scoring high on secondary psychopathy traits (Self-Centered Impulsivity group) displayed stronger physiological reactivity during a habituation phase of prolonged social exclusion than individuals scoring high on primary psychopathy traits (Fearless Dominance group), indexed by changes in skin conductance level. Moreover, a potential mismatch between self-reported and physiological arousal seemed to be only observable in individuals with high secondary psychopathy traits. Overall, the current results suggest diverging patterns of emotional processing and regulation in a social exclusion situation when comparing well-functioning individuals with varying psychopathy traits. It seemed as if individuals high on primary psychopathy traits were insensitive to contextual social cues, while individuals high on secondary psychopathy traits were more affected by the potentially threatening social situation. Cautiously transferring the current findings to forensic samples, they support the idea of moving from a behavioral understanding of the psychopathy construct to a more clinical picture with distinct cognitive and emotional processing patterns in individuals high on either primary or secondary psychopathy traits.

    与跨文化背景下的明确自我报告评级相比,本研究调查了内隐生理措施提供客观情感食物体验的潜力。荷兰和泰国参与者观看了120个食物图像,描绘了通用食物图像类别(常规和模制食物)和文化食物图像类别(通常是荷兰和泰国食物)。普遍的食物图像被作为地面实况高和低价态刺激,在那里,我们假设不同民族之间的情感经验没有真正的差异。相比之下,对于文化食品图像,我们确实期望国籍之间存在真正的差异。参与者被要求对效价进行评分,唤醒和喜欢每个食物的形象。此外,记录心率(HR)和阶段性皮肤电活动(EDA)对图像的反应。通常,亚洲和西方的反应偏见被发现对常规和模制食品的明确评级,对荷兰人具有极端的反应风格,和泰国参与者的中间反应风格。然而,在HR中未观察到这种偏倚.对于文化食品形象类别,HR显示了参与者国籍和食物图像类别之间的假设相互作用,反映了民族在情感食物体验上的预期真正差异。除了向参与者展示图像外,我们还要求参与者品尝典型的泰国和荷兰饮料。类似于图像,对于HR,发现参与者国籍和文化食物类别之间存在显著的交互作用.还发现了sip大小的相互作用,虽然这在明确的措施中没有看到。我们将此归因于采取这些措施时的差异。在这项研究中,阶段性EDA似乎不是情感食物体验的敏感量度,可能是因为刺激大多在效价而不是唤醒上有所不同。最后,我们的研究构成了一个例子,文化偏见对自我报告的准确性产生了负面影响,只有隐含的生理测量遵循了先前对真正食物体验的期望,表明这些措施研究跨文化饮食体验的潜力。
    The present study investigated the potential of implicit physiological measures to provide objective measures of affective food experience in contrast to explicit self-report ratings in a cross-cultural context. Dutch and Thai participants viewed 120 food images portraying universal food image categories (regular and molded food) and cultural food image categories (typically Dutch and Thai food). The universal food images were taken as ground truth high and low valence stimuli, where we assumed no genuine difference in affective experience between nationalities. In contrast, for the cultural food images, we did expect a genuine difference between nationalities. Participants were asked to rate valence, arousal and liking of each food image. In addition, heart rate (HR) and phasic electrodermal activity (EDA) responses to the images were recorded. Typically Asian and Western response biases were found for explicit ratings of regular and molded food with an extreme response style for Dutch, and a middle response style for Thai participants. However, such bias was not observed in HR. For cultural food image categories, HR showed the hypothesized interaction between participant nationality and food image category, reflecting the expected genuine difference between nationalities in affective food experience. Besides presenting participants with images, we also asked participants to taste typically Thai and Dutch drinks. Similar to images, a significant interaction between participant nationality and cultural food category was found for HR. An interaction was also found for sip size, while this was not seen in explicit measures. We attribute this to differences in the moment that these measures were taken. In this study, phasic EDA did not appear to be a sensitive measure of affective food experience, possibly since stimuli mostly differed in valence rather than arousal. To conclude, our study constitutes an example where cultural bias negatively affected the accuracy of self-reports, and only the implicit physiological measures followed the prior expectations of genuine food experience, indicating the potential of these measures to study cross-cultural food experience.

    分析1例少汗症外胚层发育不良(HED)患者的致病基因,探讨致病基因与寡头表型的关系。
    从患有HED的患者收集临床数据和外周血。通过全外显子测序(WES)分析致病基因,并通过Singer测序进行验证。预测变体蛋白的二级和三级结构以分析它们的毒性。
    患者表现出严重的寡头畸形表型,其中上颚只剩下两个落叶犬。WES揭示了半合子EDA变体c.466C>Tp。(Arg156Cys)和新的杂合EVC2变体c.1772T>Cp。(Leu591Ser)。EDA变体p.(Arg156Cys)和EVC2变体p.(Leu591Ser)的二级和三级结构的预测表明两种分子的功能受损。
    与由EDA变体c.466C>T引起的其他患者相比,该患者表现出更严重的寡头畸形表型。由于Evc2是SonicHedgehog(Shh)信号通路的正调节因子,我们推测EVC2变异体p.(Leu591Ser)可能在HED的寡头表型中发挥协同作用,从而加剧了寡头表型。了解由多个基因变异引起的寡头畸形对于理解寡头畸形表型的个体差异具有重要意义。
    UNASSIGNED: To analyse the pathogenic genes in a patient with hypohidrotic ectodermal dysplasia (HED) and explore the relationship between pathogenic genes and the oligodontia phenotype.
    UNASSIGNED: Clinical data and peripheral blood were collected from a patient with HED. Pathogenic genes were analysed by whole-exon sequencing (WES) and verified by Singer sequencing. The secondary and tertiary structures of the variant proteins were predicted to analyse their toxicity.
    UNASSIGNED: The patient exhibited a severe oligodontia phenotype, wherein only two deciduous canines were left in the upper jaw. WES revealed a hemizygous EDA variant c.466C > T p.(Arg156Cys) and a novel heterozygous EVC2 variant c.1772T > C p.(Leu591Ser). Prediction of the secondary and tertiary structures of the EDA variant p.(Arg156Cys) and EVC2 variant p.(Leu591Ser) indicated impaired function of both molecules.
    UNASSIGNED: The patient demonstrated a more severe oligodontia phenotype when compared with the other patients caused by the EDA variant c.466C > T. Since Evc2 is a positive regulator of the Sonic Hedgehog (Shh) signal pathway, we speculated that the EVC2 variant p.(Leu591Ser) may play a synergistic role in the oligodontia phenotype of HED, thereby exacerbating the oligodontia phenotype. Knowledge of oligodontia caused by multiple gene variants is of great significance for understanding individual differences in oligodontia phenotypes.
