Holding the body in mind: Interoceptive awareness, dispositional mindfulness and psychological well-being

Objective Recent dialogue between Western and Eastern traditions has stimulated novel explorations of the relationship between mind and body. Many of these cross-cultural, mind-body dialogues have proven productive in identifying more adaptive forms of embodiment. Prior studies suggest that dispositional mindfulness (DM) and interoceptive awareness (IA) are associated but distinct, key constructs in mind-body approaches that are conceptualized in a variety of ways with imprecisely characterized relationship. The current study is a secondary data analysis that explores the relationship between scores on measures of IA and DM, examining multivariate networks of association between these constructs and addressing their relationship with scores on a measure of psychological well-being.MethodParticipants (n=478) were American adults completing measures of interoceptive awareness (as measured by the Multidimensional Assessment of Interoceptive Awareness; MAIA), dispositional mindfulness (as measured by the Five Facet Mindfulness Questionnaire; FFMQ), and psychological well-being (as measure by the Scales of Psychological Well-Being; SPWB) online. The average participant age was 36.44 (S.D.=12.17), and 57% were female.ResultsCorrelational results from his study indicated that the IA scales and DM facets form two associative clusters. Canonical correlation analysis supported this finding, revealing that two primary networks of association exist between IA and DM, a Regulatory Awareness cluster and an Acceptance in Action cluster. Finally, hierarchical linear regression demonstrated that the self-report measures of IA and DM shared considerable variance, but also explained unique portions of the variance in psychological well-being.ConclusionThis psychometric investigation demonstrates that IA and DM are tightly interwoven, partly overlapping constructs. Indeed, greater DM is strongly linked with greater IA. Additionally, both IA and DM appear to be independently associated with enhanced psychological well-being. Future research should investigate how mindfulness practices moderate IA for therapeutic implications

Prospects for the Improvement of Energy Performance in Agroindustry Using Phase Change Materials

This work was partially supported by the Fundação para a Ciência e Tecnologia, UIDB/00066/2020 (CTS – Center of Technology and Systems).The use of Phase Change Materials (PCMs), able to store latent heat, represents an opportunity to improve energy efficiency in the agroindustry by means of thermal energy storage. PCMs provide higher energy density then sensible heat storage mediums, thus paving the way to multiple applications, like supporting the integration of renewables or allowing for new storage architectures, decentralized and directly installed in the chain production equipment, creating e.g. the opportunity to recover and value low-grade operational heat sub-products. Such new and decentralized architecture, not currently applied in agroindustry, is proposed in this work. A chocolate tempering machine using an organic PCM is conceived and analyzed using ANSYS Fluent software for computational fluid dynamics simulations, comparing the main aspects in the storage capacity and discharging process with a conventional sensitive heat storage solution that uses water. PCMs allows improving the stored energy, keeping the chocolate in the working temperature after being tempered for more than four times longer than using only hot water. If the PCMs are charged by renewables, the self-consumption ratio can be improved while providing energy flexibility to the user.authorsversionpublishe

Maximising self-care through familiarity: The role of practice effects in enhancing music listening and progressive muscle relaxation for pain management

Distraction and relaxation are regularly recommended as part of Pain Management Programmes, with increasing research highlighting the inclusion of music as part of pain management toolkit. However minimal research has assessed the role of practice effects or familiarity with these techniques when used consistently over time. Passive distraction(participant-selected preferred music) and active distraction (Progressive Muscle Relaxation; PMR) were compared against a no distraction control on the cold-pressor test (CPT). Seventy healthy participants completed the CPT with and without distraction at baseline and one week later. Experimental participants practised their distraction strategies daily between trials (7 days), with control participants keeping an activity log. Familiarity with and preference for distractors increased significantly over time, enhancing pain threshold. PMR and music reduced anxiety, enhanced pain tolerance, minimised pain perception and pain ratings. The active distraction of PMR enhanced self-efficacy to a greater extent than music and also regulated heart rate. Repeated exposure to distraction and relaxation approaches enhanced optimal arousal and complexity, maximising pain management. It is suggested that both PMR, and music, are used together as part of a multidimensional toolkit for pain management

Testing the theory of immune selection in cancers that break the rules of transplantation

Modification of cancer cells likely to reduce their immunogenicity, including loss or down-regulation of MHC molecules, is now well documented and has become the main support for the concept of immune surveillance. The evidence that these modifications, in fact, result from selection by the immune system is less clear, since the possibility that they may result from reorganized metabolism associated with proliferation or from cell de-differentiation remains. Here, we (a) survey old and new transplantation experiments that test the possibility of selection and (b) survey how transmissible tumours of dogs and Tasmanian devils provide naturally evolved tests of immune surveillance

Humanoid Robot

A humanoid robot includes a torso, a pair of arms, two hands, a neck, and a head. The torso extends along a primary axis and presents a pair of shoulders. The pair of arms movably extend from a respective one of the pair of shoulders. Each of the arms has a plurality of arm joints. The neck movably extends from the torso along the primary axis. The neck has at least one neck joint. The head movably extends from the neck along the primary axis. The head has at least one head joint. The shoulders are canted toward one another at a shrug angle that is defined between each of the shoulders such that a workspace is defined between the shoulders

Interoception and Mental Health: A Roadmap

Interoception refers to the process by which the nervous system senses, interprets, and integrates signals originating from within the body, providing a moment-by-moment mapping of the body’s internal landscape across conscious and unconscious levels. Interoceptive signaling has been considered a component process of reflexes, urges, feelings, drives, adaptive responses, and cognitive and emotional experiences, highlighting its contributions to the maintenance of homeostatic functioning, body regulation, and survival. Dysfunction of interoception is increasingly recognized as an important component of different mental health conditions, including anxiety disorders, mood disorders, eating disorders, addictive disorders, and somatic symptom disorders. However, a number of conceptual and methodological challenges have made it difficult for interoceptive constructs to be broadly applied in mental health research and treatment settings. In November 2016, the Laureate Institute for Brain Research organized the first Interoception Summit, a gathering of interoception experts from around the world, with the goal of accelerating progress in understanding the role of interoception in mental health. The discussions at the meeting were organized around four themes: interoceptive assessment, interoceptive integration, interoceptive psychopathology, and the generation of a roadmap that could serve as a guide for future endeavors. This review article presents an overview of the emerging consensus generated by the meeting

Single-cell analysis tools for drug discovery and development

The genetic, functional or compositional heterogeneity of healthy and diseased tissues presents major challenges in drug discovery and development. Such heterogeneity hinders the design of accurate disease models and can confound the interpretation of biomarker levels and of patient responses to specific therapies. The complex nature of virtually all tissues has motivated the development of tools for single-cell genomic, transcriptomic and multiplex proteomic analyses. Here, we review these tools and assess their advantages and limitations. Emerging applications of single cell analysis tools in drug discovery and development, particularly in the field of oncology, are discussed

The feeling of me feeling for you: Interoception, alexithymia and empathy in autism.

Following recent evidence for a link between interoception, emotion and empathy, we investigated relationships between these factors in Autism Spectrum Disorder (ASD). 26 adults with ASD and 26 healthy participants completed tasks measuring interoception, alexithymia and empathy. ASD participants with alexithymia demonstrated lower cognitive and affective empathy than ASD participants without alexithymia. ASD participants showed reduced interoceptive sensitivity (IS), and also reduced interoceptive awareness (IA). IA was correlated with empathy and alexithymia, but IS was related to neither. Alexithymia fulfilled a mediating role between IA and empathy. Our findings are suggestive of an alexithymic subgroup in ASD, with distinct interoceptive processing abilities, and have implications for diagnosis and interventions
