Differential sensitisation to central cardiovascular effects of angiotensin II in rats with a myocardial infarct: relevance to stress and interaction with vasopressin

The purpose of the present study was to elucidate if rats with myocardial infarction manifest altered responsiveness to central cardiovascular effects of low doses of angiotensin II (ANG II), and if ANG II and vasopressin (VP) cooperate in the central regulation of cardiovascular functions at rest and during stress. Conscious Sprague-Dawley rats with myocardial infarction induced by left coronary artery ligation, or sham-ligated (SL) controls were infused intracerebroventricularly with artificial cerebrospinal fluid (aCSF), ANG II, ANG II + VP or ANG II + V1a receptor antagonist (V1ANT) 4 weeks after cardiac surgery. In the infarcted but not in the SL rats, the resting mean arterial blood pressure (MABP) was significantly elevated by infusions of ANG II and ANG II + VP, while infusion of ANG II + V1ANT was not effective. During administration of aCSF, the pressor, and tachycardic responses to an air-jet stressor were significantly greater in the infarcted than in the SL rats. In the SL rats, the pressor responses to the stressor were significantly greater during infusions of ANG II, ANG II + VP and ANG II + V1ANT than during infusion of aCSF. The tachycardic response in the SL rats was enhanced only by the combined infusion of ANG II + VP. In the infarcted rats, the pressor and the tachycardic responses to the stressor were similar in all groups. It is concluded that: (1) under resting conditions the infarcted rats manifest sensitisation to the central pressor effect of ANG II and that this effect depends on concomitant stimulation of V1a VP receptors, (2) central ANG II may enhance the pressor response to an alarming stressor in the SL rats through an action which does not depend on the concomitant stimulation of V1a receptors, (3) the cooperative action of ANG II and VP is required for intensification of the tachycardic response to the alarming stressor in the SL rats and (4) exaggeration of the cardiovascular responses to the alarming stressor in the infarcted rats cannot be further augmented by an additional stimulation of central ANG II receptors or combined stimulation of ANG II and VP receptors.     

Facial affect and temporal order judgments: emotions turn back the clock

The influence of facial affect on the perception of temporal order was examined in the context of the temporal order judgment (TOJ) paradigm. Two schematic faces were presented either simultaneously, or separated by varying stimulus onset asynchronies (SOAs; -100 ms, -34 ms, -17 ms, 17 ms, 34 ms, 100 ms), and participants had to judge which face appeared first. Each schematic face displayed one of three emotions; happy, neutral, or angry. Facial affect was found to influence judgments of temporal order at short SOAs (-17 ms, 0 ms, and 17 ms) but not at the longest SOAs (-100 ms and 100 ms), consistent with the hypothesis that facial affect influences relative onset judgments when they are difficult to make.     

The Boundaries of Woman’s Spirituality in the Beliefs–Spirituality–Religiousness (B–S–R) Model: A Third Perspective—Beliefs as a Cognitive Basis

The real nature of the phenomenon of woman’s Spirituality is the main contemporary challenge for empirical research. The literature needs many more examples of the cognitive genesis of worldviews, Spirituality and Religiousness. The first aim of this article is to present the central tenet of the Threefold Nature of Spirituality model which theoretically explains the nature of Spirituality and the theoretical relationship between beliefs (worldviews), Spirituality and Religiousness (B–S–R model). The second aim is the empirical verification of this relationship through the application of an analysis of mediation. The 308 participants were women aged 18–50 years (M = 25.25, SD = 9.42). The results obtained indicate that is a good mediator between an individual’s worldview and Religiousness. Presented analysis of mediation allows us to describe the basic functioning mechanism of the spiritual sphere and the relationship between the three elements: worldview, Spirituality and Religiousness.     

Values Realized in Personal Strivings and Motivation,and Meaning in Life in Polish University Students

The present study was based on two theoretical conceptions—Deci and Ryan’s self-determination theory and its characteristic approach to values, and the conception of meaning in life derived from the Logotherapy of Frankl. The aim of the study was to verify the thesis that values realized in personal strivings play a significant role in experiencing meaning in life. The study was also designed to explore the relationships between types of motivation and meaning in life. A semi-open method was used to study values and striving motivations, one based on the Personal Striving Assessment by Emmons and the Purpose in Life Test by Maholick and Crumbaugh. The sample comprised 353 students of Wroc?aw-based universities (159 women and 194 men). The findings of this study demonstrated that meaning in life is related to motivation as well as to certain values that participants reported as realized in their personal strivings. Predictors of meaning in life were the value of financial success for men, and the value of intimacy/friendship for women. Another predictor of meaning for both groups was external motivation. Further interesting results discussed in this paper were obtained by comparing individuals with low and those with high levels of meaning in life. The latter group was found to attribute greater importance to autonomous motivation and to attach greater meaning to their everyday strivings by associating them more closely with both intrinsic and extrinsic values.     

The Mediating Role of Resiliency in the Relationship Between Temperament and Posttraumatic Growth

The purpose of the research is to investigate the mediating role of resiliency in the relation between temperamental traits and posttraumatic growth. Data of 74 persons who have experienced the death of someone close were analyzed. The range of age of the participants was 21–74 years (M = 38.4; SD = 15.5). The Posttraumatic Growth Inventory (PTGI), the Formal Characteristics of Behavior–Temperament Inventory (FCB-TI), and the Resiliency Assessment Scale were used in the study. Resiliency plays a mediating role among four traits of temperament (Briskness, Emotional Reactivity, Endurance, and Activity) and posttraumatic growth. Resiliency seems to modify the direct impact of temperamental traits on positive posttraumatic changes.     

Miłosz and Wat read Brzozowski

The paper discusses the impact of the thought of Stanisław Brzozowski (1878–1911) on several Polish emigré writers, including Józef Czapski and Gustaw Herling-Grudziński, but first of all Czesław Miłosz (1911–2004) and Aleksander Wat (1900–1967). Miłosz’ approach oscillated between early fascination through an unjust rejection during the war, due to the “appropriation” of Brzozowski’s thought by the right wing publicists, to the new phase of fascination after the war, culminating in the publication of a book on Brzozowski (A Man Among Scorpions, 1962) and prolonged in several important articles till the very end of his life. Wat’s approach shifted from the communist practice of “overcoming” Brzozowski through the affirmation of his criticism and rejection of catholic obscurantism to the process of the internalization of the catholic faith.

Development of a Biomedical Program of Research in the Blackfeet Community: Challenges and Rewards

American Indian (AI) communities have high levels of stress and trauma and are disproportionately affected by numerous preventable diseases. Here, we describe an academic–community partnership based on a collaboration between Blackfeet Community College students and faculty in Psychology and Immunology at Montana State University (MSU). The collaboration, which has spanned over 5 years, was sparked by community interest in the relationship between stress and disease on the Blackfeet reservation. Specifically, community members wanted to understand how the experience of psychological stress and trauma may affect disease risk in their community and identify factors that promote resilience. In doing so, they hoped to identify pathways through which health could be improved for individual community members. Here, we discuss all stages of the collaborative process, including development of measures and methods and themes of research projects, challenges for community members and non‐indigenous collaborators, future directions for research, and the lessons learned. Finally, we note the ways in which this partnership and experience has advanced the science of community engagement in tribal communities, with the hope that our experiences will positively affect future collaborations between indigenous community members and non‐indigenous scientists.

Between womanhood as ideal and womanhood as a social practice: women’s experiences in the Church organisation in Poland

Using the conceptual framework proposed by Susan Sered and institutional gender theories, this article analyses the relationship between the symbolic and idealised image of femininity with which Catholic women working in the organisations of the Roman Catholic Church in Poland identify themselves and practices of femininity in the structures of Church institutions. I locate the difficulties experienced by women in the Church in realising this symbolic image of femininity. At the same time, I identify the strategies taken by women as ways of dealing with the difficulties and as practices of achieving normative femininity in unfavourable circumstances. I analyse three types of strategies: sacralising difficulties and experienced barriers, familiarising relationships in the Church, and affirming femininity. The article examines the content of interviews conducted between 2012 and 2015 with 31 laywomen working in Church organisations in 15 dioceses in Poland and in the Episcopal Conference, who held three types of positions: office workers/secretaries, professionals, and directors.
