Epigenetic and transcriptional variability contribute to the vast diversity of cellular and organismal phenotypes and are key in human health and disease. In this review, we describe different types, sources, and determinants of epigenetic and transcriptional variability, enabling cells and organisms to adapt and evolve to a changing environment. We highlight the latest research and hypotheses on how chromatin structure and the epigenome influence gene expression variability. Further, we provide an overview of challenges in the analysis of biological variability. An (...) improved understanding of the molecular mechanisms underlying epigenetic and transcriptional variability, at both the intra- and inter-individual level, provides great opportunity for disease prevention, better therapeutic approaches, and personalized medicine. Epigenetic and transcriptional variability mediate phenotypic plasticity, enabling adaptation to changing environments. In this review, we describe the sources of inter- and intra-individual variability and discuss epigenetic regulators of gene expression variability, including DNA methylation and chromatin structure. Understanding these molecular mechanisms will improve therapeutic approaches and personalized medicine. (shrink)

ABSTRACTFeelings and cognitions influence judgment through attribution. For instance, the attribution of positive feelings and cognitions to a stimulus leads to a positive judgment of that stimulus. We examined whether misattribution is moderated by the applicability of a distractor to the judgment question. For instance, when are people more likely to attribute to a target person the affective and cognitive experiences triggered by a kitten – when trying to judge the person’s cuteness or trustworthiness? The kitten triggers experiences specifically relevant (...) to cuteness, but people might more easily suspect the kitten’s potential influence when judging cuteness rather than trustworthiness. Using the Affect Misattribution Procedure, we found that applicability increases the effect of misattribution on valenced judgments. The results emphasise the importance of specific information in attribution and suggest that high applicability of distractors to the judgment question d... (shrink)

Is consolidation needed to account for retroactive interference in free recall? Interfering mental activity during the retention interval of a memory task impairs performance, in particular if the interference occurs in temporal proximity to the encoding of the to-be-remembered information. There are at least two rival theoretical accounts of this temporal gradient of retroactive interference. The cognitive neuroscience literature has suggested neural consolidation is a pivotal factor determining item recall. According to this account, interfering activity interrupts consolidation processes that would (...) otherwise stabilize the memory representations of TBR items post-encoding. Temporal distinctiveness theory, by contrast, proposes that the retrievability of items depends on their isolation in psychological time. According to this theory, information processed after the encoding of TBR material will reduce the temporal distinctiveness of the TBR information. To test between these accounts, implementations of consolidation were added to the SIMPLE model of memory and learning. We report data from two experiments utilizing a two-list free recall paradigm. Modeling results imply that SIMPLE was able to model the data and did not benefit from the addition of consolidation. It is concluded that the temporal gradient of retroactive interference cannot be taken as evidence for memory consolidation. (shrink)

BackgroundIn the early phase of the COVID-19 pandemic, many restrictions hit people in ways never seen before. Mental wellbeing was affected and burden was high, especially for high-risk groups such as parents. However, to our knowledge no research has yet examined whether being a parent was not only a risk for psychological burden but also a way to cope with the COVID-19 pandemic.MethodsAn online survey was used to collect data from 1,121 participants from April to June 2020. In addition to (...) demographic variables, risk factors and protective factors were collected. The dataset was divided into three groups: parents whose children lived at home, parents whose children did not live at home, and people who were not parents.ResultsA linear mixed effect model showed that parents had no higher burden than non-parents, and even less when children did not live at home. Expected risk factors were generally less important, and there were no differences between parents and non-parents. In contrast, parents had advantages in protective factors.ConclusionIn the early phase of the COVID-19 pandemic, it was shown that parents were not necessarily at risk due to additional burden, but also had prospects of coping better with the situation than people without children.

That memory reconsolidation is the process underlying decisive, lasting therapeutic change has long been our proposal, and the recognition of its critical role by Lane et al. is a welcome development. However, in our view their account has significant errors due to neglect of research findings and neglect of previous work on the clinical application of those findings.

An inscribed marble gable found near the ancient city center of Ascalon (modern Ashkelon) is published. The inscription (of AD 220) records the erection and dedication of a temple in honor of the goddess “Ourania of Skorpon”. Ourania Aphrodite was a resident deity in Ascalon and this appears to be the first tangible piece of evidence confirming the ancient ties linking her to the city. The word egersitheos, revivifier of a deity, in this inscription is otherwise unattested.

Este artículo intenta iluminar el problema de las traducciones de inscripciones árabes medievales durante el Barroco, en particular, las propuestas por Rodrigo Caro en 1643 de las inscripciones de Sevilla, traducciones primero ignoradas y luego consideradas, en el siglo XIX, como fraudulentas. Aquí se propone que estas falsas traducciones están condicionadas por el contexto de las de los Plomos del Sacromonte, por el ideal de la época de «antigüedad sagrada» y por el interés contrarreformista en ensalzar mártires y reliquias. Estos (...) eran todos elementos de un programa consciente de invención de un pasado cristiano, ficticio pero lleno de significado, en Andalucía. Los principales protagonistas de las traducciones de Sevilla, Rodrigo Caro, Pedro de Castro, Adán Centurión, estuvieron implicados en este proceso además de formar parte de una red, que implicaba a toda la península, de entusiastas anticuarios y falsarios. Su juicio crítico, cuando se enfrentaba con fraudes evidentes, quedaba obnubilado por su deseo de promover determinados fines religiosos y políticos. Sus traductores, que a menudo compartieron, era los productores de caprichosos instrumentos con que alcanzar dichos fines. (shrink)

Research on the effects of perceptual manipulations on recognition memory has suggested that recollection is selectively influenced by task-relevant information and familiarity can be considered perceptually specific. The present experiment tested divergent assumptions that perceptual features can influence conscious object recollection via verbal code despite being task-irrelevant and that perceptual features do not influence object familiarity if study is verbal-conceptual. At study, subjects named objects and their presentation colour; this was followed by an old/new object recognition test. Event-related potentials showed (...) that a study-test manipulation of colour impacted selectively on the ERP effect associated with recollection, while a size manipulation showed no effect. It is concluded that verbal predicates generated at study are potent episodic memory agents that modulate recollection even if the recovered feature information is task-irrelevant and commonly found perceptual match effects on familiarity critically depend on perceptual processing at study.

Home births continue to constitute only a small percentage of all deliveries in the United States, in part because of concerns about their safety. While the literature is decidedly mixed in regard to the degree of risk, there are several studies that report that home birth may at times entail a small absolute increase in perinatal risks in circumstances that cannot always be anticipated prior to the onset of labor. While the definition of “small” will vary between individuals, and publications (...) vary in the level of risk they ascribe to birth at home, studies with the least methodological flaws and with adequate power often cite an excess death rate in the range of one per thousand.Home birth is, in that regard, but one example of patients’ choices and plans that sometimes carry increased risk or include alternatives that individual physicians feel uncomfortable supporting or recommending. Our intention in this opinion piece is not to advocate for or against home birth. Rather, we recognize that home birth is but one example of a patient choice that might differ from what a provider feels is in a woman’s best interests.In this article we will discuss ethical considerations in such circumstances using home birth as an example. We consider in this article how the ethical principles of respect for autonomy and non-maleficence can be balanced using, among other examples, the choice by some for a home birth. We discuss how absolute rather than relative risk should guide individuals’ evaluation of patient choices. We also consider how in some circumstances, the value and safety added by a physician’s participation may outweigh a potentially small increment in absolute risk that might result from a patient’s decision to deliver at home because of a perceived physician endorsement.We recognize, however, that doctors and midwives participating in choices they have not recommended, or may even believe will lead to or increase risk for adverse outcomes, presents dilemmas and raises important questions. When does respect for patient choice and autonomy become support for poor decision making? When is participation not respectful but enabling? Finally we discuss the role and responsibility of organized medicine in making all births as safe as possible. (shrink)

ABSTRACTPeople often continue to rely on misinformation in their reasoning after they have acknowledged a retraction; this phenomenon is known as the continued-influence effect. Retractions can be particularly ineffective when the retracted misinformation is consistent with a pre-existing worldview. We investigated this effect in the context of depressive rumination. Given the prevalence of depressotypic worldviews in depressive rumination, we hypothesised that depressive rumination may affect the processing of retractions of valenced misinformation; specifically, we predicted that the retraction of negative misinformation (...) might be less effective in depressive ruminators. In two experiments, we found evidence against this hypothesis: in depressive ruminators, retractions of negative misinformation were at least as effective as they were in control participants, and more effective than retractions of positive misinformation. Findings are interpreted in terms of an attentional bias that may enhance the sali... (shrink)

Research on cognitive control has sparked increasing interest in recent years, as it is an important prerequisite for goal oriented human behavior. The paced auditory serial addition task has been used to test and train cognitive control functions. This adaptive, challenging task includes continuous performance feedback. Therefore, additional cognitive control capacities are required to process this information along with the already high task-load. The underlying neural mechanisms, however, are still unclear. To explore the neural signatures of the PASAT and particularly (...) the processing of distractive feedback information, feedback locked event-related potentials were derived from 24 healthy participants during an adaptive 2-back version of the PASAT. Larger neural activation after negative feedback was found for feedback related negativity, P300, and late positive potential. In early stages of feedback processing, a larger difference between positive and negative feedback responses was associated with poorer overall performance. This association was inverted in later stages. Together, our findings indicate stage-dependent associations between neural activation after negative information and cognitive functioning. Conceivably, increased early responses to negative feedback signify distraction, whereas higher activity at later stages reflects cognitive control processes to preserve ongoing performance.

To delineate what it means to discover truth, to act in freedom, to be creative, to live authentically, and to aspire to transcend the time and space dimension is the intent of this book. The subject is treated thematically through the analysis of the opposites of materialism and immaterialism, whereas selected traditional and contemporary philosophical themes demonstrate the philosophical mean.

The exhibition ba [does not equal to] b+a explores the question of how a museum's activities--its mechanisms, modes of operation, and logics--are reflected in the works in its collection. On the occasion of MUSA's tenth anniversary, the museum's program of exhibitions and publications takes a self-reflective turn, shedding light on the specific characteristics of Vienna's municipal art collection, whose origins go back to the 1950s, and raising far-reaching questions concerning the museum as an institution. The assumption underlying the exhibition is (...) that the objects in a museum's collection are crucial to its character. They may seem to be innumerable separate pieces--but the museum is more than their mere juxtaposition. "That which is composed of something in such a way that the whole is a unity," Aristotle writes, "is a unity not as an aggregate is a unity, but as a syllable is. The syllable is not the letters, nor is BA the same as B and A; nor is flesh fire and earth." It is only in the interweaving of the individual components, in their layering and inexhaustible potential constellations, that they engender the necessary density that lets us understand, and interact with, the museum as a living archive.

Background To determine whether fetal care paediatric and maternal–fetal medicine specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care.Methods Mail survey of 434 MFM and FCP specialists .Results MFMs were more likely than FCPs to disagree with these statements : ‘the (...) presence of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination’ ; ‘the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination’ ; and ‘the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination’ . 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being . Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes.Conclusions Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

The aim of this paper is to challenge the claim that the neural activity commonly referred to as 'readiness potential' constitutes evidence for the unconscious initiation of action. Although I accept that such neural activity seriously challenges the commonly held view that one's sense of volition is causally efficacious, I nevertheless contend that much of our everyday engagement with the world is consciously initiated. Thus, a distinction is made between awareness and what the awareness is of: the latter constituting the (...) conscious decision to act in accordance with one's goal, or what I have termed intentional project. Initiation of an action in accordance with one's intentional project grounds the action in meaning, something that would be lacking in an exclusively unconscious decision to act. (shrink)
