Plants have a unique transdifferentiation mechanism by which differentiated cells can initiate new program of differentiation. We used comprehensive analysis gene expression in an vitro zinnia ( Zinnia elegans L.) culture model system to gather fundamental information about the regulation underlying plant cells. In this model, photosynthetic mesophyll isolated from leaves transdifferentiate into xylem morphogenic process characterized features such as secondary-wall formation and programmed...
Our attitude toward risk plays a crucial role in influencing our everyday decision-making. Despite its importance, little is known about how human risk-preference can be modulated by observing risky behavior other agents at either the behavioral or neural level. Using fMRI combined with computational modeling of data, we show that systematically altered act and learning from others' risk-related decisions. The contagion driven specifically brain regions involved assessment risk: shift...
Cooperation among genetically unrelated individuals is a fundamental aspect of society, but it has been longstanding puzzle in biological and social sciences. Recently, theoretical studies biology economics showed that conditional cooperation—cooperating only with those who have exhibited cooperative behavior—can spread over society. Furthermore, experimental psychology demonstrated people are actually cooperators. In this study, we used functional magnetic resonance imaging to investigate...
Internal (neuronal) representations in the brain are modified by our experiences, and this phenomenon is not unique to sensory motor systems. Here, we show that different impressions obtained through social interaction with a variety of agents uniquely modulate activity dorsal ventral pathways network mediates human behavior. We scanned functional magnetic resonance imaging (fMRI) 16 healthy volunteers when they performed simple matching-pennies game human, human-like android, mechanical...
The evolution of cooperation in social dilemmas has been considerable concern various fields such as sociobiology, economics and sociology. It might be that, the real world, reputation plays an important role cooperation. Recently, studies that have addressed indirect reciprocity revealed can evolve through reputation, even though pairs individuals interact only a few times. To our knowledge, most models presumed dyadic interaction; no attempted analysis large communities where effect is...
In addition to conventional cytology, liquid-based cytology (LBC) is also used for immunocytochemistry and gene analysis. However, an appropriate method obtain high quality DNA next-generation sequencing (NGS) using LBC specimens remains controversial. We determined the optimal conditions fixation with alcohol-based fixative extraction cultured cancer cell lines clinical specimens. The extracted was processed NGS after confirmed based on concentration degree of degradation. cells were fix at...
Metacognition, the ability to monitor and reflect on our own mental states, enables us assess performance at different levels – from confidence in individual decisions overall self-performance estimates (SPEs). It plays a particularly important part computationally complex that require high level of cognitive resources, as allocation such limited resources presumably is based metacognitive evaluations. However, little known about metacognition decisions, particular, how people construct...
Food preferences differ among individuals, and these variations reflect underlying personalities or mental tendencies. However, capturing predicting individual differences remains challenging. Here, we propose a novel method to predict food by using CLIP (Contrastive Language-Image Pre-Training), which can capture both visual semantic features of images. By applying this image rating data obtained from human subjects, demonstrated our method's prediction capability, achieved better scores...
How natural selection can promote cooperative or altruistic behavior is a fundamental question in biological and social sciences. One of the persuasive mechanisms "indirect reciprocity," working through reputation: prevail because builds donor's good reputation then s/he receives some reciprocal benefits from someone else community. However, an important piece missed previous studies that reputation-building process requires substantial cognitive abilities such as communication skills,...
Objective: Chronic rhinosinusitis with nasal polyps exhibits marked eosinophilic infiltration and its mucosal eosinophilia is associated more severe symptoms. The Japanese epidemiological survey of refractory chronic found that patients required multiple surgeries when there were 70 or infiltrating eosinophils / high-power field (HPF) in the mucosa. In order to identify plasma biomarkers for local eosinophil surgery, we examined levels molecules serum compared number Materials methods:...
Adolescence is a period of life in which social influences-particularly if they come from peers-play critical role shaping learning and decision preferences. Recent studies adults show evidence risk contagion effect; that is, individual preferences are modulated by observing others' risk-related decisions. In this study, using choice data computational modeling, we demonstrate stronger male adolescents when peers compared to nonpeers. This effect was only present the observed peer showed...
Obsessive-compulsive disorder (OCD) and pathological gambling (PG) are accompanied by deficits in behavioural flexibility. In reinforcement learning, this inflexibility can reflect asymmetric learning from outcomes above below expectations. alternative frameworks, it reflects perseveration independent of learning. Here, we examine evidence for reward-learning OCD PG leveraging model-based functional magnetic resonance imaging (fMRI). Compared with healthy controls (HC), patients exhibited a...
Computational modeling is gaining increasing popularity in the field of psychiatry. By applying a machine learning framework known as reinforcement (RL), researchers domain computational psychiatry have begun to shed light on latent decision-making processes that are altered mental disorders. In this chapter, we first elucidate how RL can be instrumental estimating and learning. We then focus studies employ basic class RL, model-free gain insights into psychopathology obsessive-compulsive...
Abstract Deciding whether to wait for a future reward is crucial surviving in an uncertain world. While seeking rewards, agents anticipate the present environment and constantly face trade-off between staying their or leaving it. It remains unclear, however, how humans make continuous decisions such situations. Here, we show that anticipatory activity anterior prefrontal cortex, ventrolateral hippocampus underpins stay–leave decision-making. Participants awaited real liquid rewards available...
Social signals play powerful roles in shaping self-oriented reward valuation and decision making. These activate social valuation/decision areas, but the core computation for their integration into machinery remains unclear. Here, we study how a fundamental signal, value (others9 value), is converted making human brain. Using behavioral analysis, modeling, neuroimaging, show three-stage processing of conversion from offer to effective then final value. First, others9 bonus on offer, called...
Abstract Background Liquid-based cytology (LBC) is now a widely used method for cytologic screening and cancer diagnosis. Since the cells are fixed with alcohol-based fixatives, specimens stored in liquid condition, LBC suitable genetic analyses. Methods Here, we established small gene panel, including 60 genes 17 microsatellite markers next-generation sequencing, applied to residual obtained by endometrial compare corresponding formalin-fixed paraffin-embedded (FFPE) tissues. Results A...
Traditionally, financial market participation has been treated as analogous to playing games of chance with a physical device such roulette. Here, we propose that humans treat markets intentional agents, own beliefs and aspirations. As result, the capacity infer intentions others, Theory Mind, explains behaviour. evidence, appeal results from recent studies of: (i) forecasting in presence insiders, (ii) trading bubbles, (iii) contagion.

Body-image disturbance comprises two components. The first is perceptual in nature, and measured by a discrepancy between one’s actual body perceived self-image (“perceived–actual discrepancy”). other component affective, ideal image (“perceived–ideal present study evaluated the relationships body-image characteristics of eating disorders such as symptoms related personality traits.
