Attenuated maladaptive emotion processing as a potential mediator of the relationship between dispositional mindfulness and mental health

The emotion processing and regulation mechanisms by which dispositional (personality trait) mindfulness exerts its positive effects on mental health remain unclear. Here, we tested, using structural equation modeling, whether the relationship between higher dispositional mindfulness and better mental health is mediated by reduced maladaptive processing of emotional information (e.g., expressive suppression, impoverished emotional experiences, unprocessed emotions, avoidance, externalizing strategies) and associated lower negative affect, enhanced adaptive processing of emotional information (e.g., cognitive reappraisal) and associated higher positive affect, or a combination of these two emotion processing styles. Dispositional mindfulness, mental health, diverse emotional constructs with adaptive and maladaptive dimensions (including range and differentiation of emotional experiences, use of specific emotion regulation strategies, emotion processing deficits, negative affect repair strategies, negative mood regulation expectancies), and positive and negative affect were assessed using self-report measures in a non-clinical sample of 256 adults. The relationship between higher dispositional mindfulness and better mental health was found to be best explained by reduced maladaptive emotion processing styles and associated lower negative affect, rather than by enhanced adaptive emotion processing and higher positive affect. Further research should investigate whether the same mechanisms explain psychological benefits of cultivated mindfulness in people with low dispositional mindfulness and/or with mental health disorders following mindfulness skills training.Bial Foundation (92/18; awarded to VK and RP) and the Indian Council of Medical Research (3/1/3-ICMR-JRF/2011/HRD/12/81003; awarded to SPM)

Camera-Based Visual Feedback Learning Aid for Recovering Sense of Smell and Taste in COVID-19 Survivors: A Proof-of-Concept Study

Introduction: A significant proportion of people report persistent COVID 19-related anosmia, hyposmia or parosmia, often accompanied with ageusia, hypogeusia or dysgeusia. Here, we present a proof-of-concept study that assessed the feasibility and acceptability of a new Camera-Based Visual Feedback Learning Aid (CVFLA) and explored its potential to restore or improve persistent COVID-19-related smell and/or taste impairment. Methods: Fifteen adult participants with persistent smell and/or taste impairment were randomly allocated to 7-, 14-, or 21-days baseline of symptom monitoring before receiving the intervention in up to 10 sessions (length and frequency determined by participant’s preference and progress) using a specialised CVFLA apparatus (patent no. 10186160). Smell and taste were assessed pre- and post intervention subjectively, and also objectively using the ODOFIN Taste Strips and Sniffin Sticks. Participant feedback about their experience of receiving CVFLA was obtained via a semi-structured interview conducted by someone not involved in delivering the intervention. Results: The intervention was extremely well received, with no dropouts related to the intervention. There was also a significant improvement in smell and taste from pre- to post-CVFLA intervention (mean number of sessions = 7.46, SD = 2.55; total duration = 389.96 min, SD = 150.93) both in subjective and objective measures. All participants, except one, reported experiencing some improvement from the 2nd or 3rd session. Discussion: This new CVFLA intervention shows promise in improving COVID-19 related impairment in smell and taste with a very high level of acceptability. Further studies with larger samples are required to confirm its potential in restoring, improving or correcting smell and/or taste impairment in relevant clinical and non-clinical groups.Brunel University London, and the European Research Development Fund (EDRF) and Learning JBE Ltd. via Anglia Ruskin University.

Evaluation of the elastic properties and topography of leukocytes’ surface in patients with type 2 diabetes mellitus using atomic force microscope

The aim of study was to examine some morphometrical parameters (height, diameter) of the leukocytes (white blood cells - WBCs), their specific surface morphology (globular prominences and depression in WBCs) as well as their local elastic properties (Young’s modulus) in healthy persons and in patients with type 2 diabetes mellitus (T2DM) by means of the atomic force microscopy (AFM). Morphological and morphometrical parameters of human leukocytes were evaluated by AFM in tapped mod

Influence of ripening in mother solution on characteristics of magnesium-substituted calcium phosphate powders

Effect of ripening in the mother liquor on the degree of crystallinity and dispersity of mixed powders of calcium and magnesium phosphates is studied as a function of magnesium content with the elemental composition such that (Ca + Mg)/P = 2. Ripening is found to have a positive effect on crystallinity of the apatite phase of powders. Nanocrystals with lowered tendency to aggregation are formed during the ripening period, which affords the powders with specific surface area as high as 80 m2/g. The morphology of the constituent particles depends on the magnesium content. Crystallization processes are essentially completed by the 21st day of ripenin

More meditation, less habituation? The effect of mindfulness practice on the acoustic startle reflex

Background Mindfulness as a mode of sustained and receptive attention promotes openness to each incoming stimulus, even if repetitive and/or aversive. Mindful attention has been shown to attenuate sensory habituation in expert meditators; however, others were not able to replicate this effect. The present study used acoustic startle reflex to investigate the effect of mindfulness practice intensity on sensory habituation. Methods Auditory Startle Response (ASR) to 36 startling probes (12 trials x 3 block with 40ms inter-block intervals), was measured using electromyography (EMG) in three groups of participants (N = 12/group): meditation-naïve, moderate practice, and intensive practice. Results Intensive practice group showed attenuated startle habituation as evidenced by significantly less habituation over the entire experiment relative to the meditation-naïve and moderate practice groups. Furthermore, there was a significant linear effect showing between-block habituation in meditation-naïve and moderate practice groups, but not in the intensive practice group. However, the Block x Group interaction between the intensive practice and the meditation-naive groups was not significant. Moderate practice group was not significantly different from the meditation-naïve in the overall measure of habituation, but showed significantly stronger habituation than both meditation-naïve and intensive practice groups in Block 1. Greater practice intensity was significantly correlated with slower overall habituation and habituation rate in Blocks 2 and 3 in the intensive, but not in the moderate, practice group. Conclusions The study provides tentative evidence that intensive mindfulness practice attenuates acoustic startle habituation as measured by EMG, but the effect is modest. Moderate practice, on the other hand, appears to enhance habituation, suggesting the effect of mindfulness practice on startle habituation might be non-liner. Better understanding of the effect of mindful attention on startle habituation may shed new light on sensory information processing capacity of the human brain and its potential for de-automatisation of hard-wired processes.Templeton Positive Neuroscience Award (Grant number: PAHWPZA) (http://www. posneuroscience.org/research-awards.html)

Yakut Emigration: Features of Adaptation and Communication

The issues of adaptation of Yakut emigrants forced to escape the revolution, the Civil War and the Gulag to different countries are considered. The role of Yakut emigrants in the preservation of national-cultural identity is described. Their participation in the civilizational dialogue between East and West is emphasized. A classification of the stages of the formation of local groups and microgroups of Yakut emigrants in the countries of the world is suggested. The approximate number, composition and territorial distribution of Yakut emigrants in China (the central group), Japan (southern Sakhalin), Finland, and the presence of microgroups in the USA and Australia are established. Attention is paid to the specifics of interaction of Yakut emigrants in the absence of a registered organization through communication, in which organizational, ideological, material activities were carried out. It is proved that correspondence was carried out in Russian, English, and various transcriptions of the Yakut script were used: Bötlingkowski, Novgorodovski, Cyrillic. Particular attention is paid to the high mobility of the Yakut emigrants, their desire to master new languages, qualifications and education for successful adaptation abroad. It is concluded that the Yakut emigrants failed to form a mechanism for the reproduction of ethnic identity (language, culture) in a foreign land. It was established that there was no organized opposition to repatriation by Yakut emigrants, but all returnees were unreasonably repressed by the NKVD
