Symbioses and Stress centers on the question of how organisms in tight symbiotic associations cope with various types of abiotic and biotic stress. In its original sense, symbioses cover all kinds of ...interactions among unrelated organisms, whereas in a narrower concept, the term is often referred to as mutualism. Evolutionary biology recognizes symbiosis as an integrative process, and most fundamental evolutionary innovations arose from cooperative symbioses. Mutualisms contribute to stress tolerance, ecosystem stability, and evolutionary radiation of cooperating organisms. Modern eukaryotic cells are the result of the endosymbiotic union of prokaryotic ancestors as well as diverse exosymbiotic associations. This cooperative aggregation appears more successful than its independent parts. This new book presents functional and evolutionary aspects of mutually beneficial symbioses among unrelated organisms.
In the United States the economically disadvantaged and some ethnic minorities are often exposed to chronic psychosocial stressors and disproportionately affected by asthma. Current evidence suggests ...a causal association between chronic psychosocial stress and asthma or asthma morbidity. Recent findings suggest potential mechanisms underlying this association, including changes in the methylation and expression of genes that regulate behavioral, autonomic, neuroendocrine, and immunologic responses to stress. There is also evidence suggesting the existence of susceptibility genes that predispose chronically stressed youth to both post-traumatic stress disorder and asthma. In this review we critically examine published evidence and suggest future directions for research in this field.
Exposure to violence has negative consequences on mental health. Armed-conflict in Colombia has widely affected Afro-descendants in the Pacific region. Evidence regarding effectiveness of mental ...health interventions is lacking in low-income settings, especially in areas with active conflict. The objective of this study is to evaluate an individualized Common Elements Treatment Approach (CETA), a transdiagnostic psychotherapy model based on Cognitive-Behavioral Therapy, for adult trauma survivors.
A referred sample of 521 adult Afro-descendants from Buenaventura and Quibdó, Colombia, experiencing significant sadness, suffering or fear (score>0.77 in Total Mental Health Symptoms), with history of traumatic experiences, and with associated functional impairment were randomly allocated to CETA intervention, standby group without intervention, but under monthly monitoring, or a Narrative Community-Based Group Therapy. CETA was provided by trained Lay Psychosocial Community Workers without previous mental health experience, supervised by psychologists, during 12-14 weekly, 1.5-hour sessions. Symptoms were assessed with a locally validated survey built based on the Hopkins Symptom Checklist, the Harvard Trauma Questionnaire, the PTSD CheckList-Civilian Version, a qualitative study for additional general symptoms and a gender-specific functional impairment scale. CETA was compared with the control group and the intervention effects were calculated with mixed models using intention to treat analysis. Participant completion of follow-up was 75.1% and 13.2% voluntarily withdrew. Reduction in post-traumatic stress symptoms was significant in both municipalities when comparing intervention and control groups (mean difference), with a with a moderate effect size in Buenaventura (Cohen's d = 0.70) and a small effect size in Quibdó (d = 0.31). In Buenaventura, the intervention also had significant effects on depression (large effect size d = 1.03), anxiety (large effect size d = 0.80) and functional impairment (moderate effect size d = 0.70). In Quibdó, it had no significant effect on these outcomes. Changes in Total Mental Health Symptoms were not significant in neither city.
This trial suggests that CETA, can be effective in improving depression, anxiety, post-traumatic stress and function among victims of systematized violence in low-income and active conflict settings. Nonetheless, the difference of effectiveness between the two cities of intervention may indicate that we cannot assume that a mental health intervention known to be effective in one setting will be effective in another, even in similar circumstances and population. This may have special importance when implementing and reproducing these types of intervention in non-controlled circumstances. Further research should address these concerns. Results can be of use by governmental decision-makers when defining mental health programs for survivors.

Based on a unique research study, this volume examines the later life development of Holocaust survivors from Israel and the US. Through systematic interviews, the authors – noted researchers and ...clinicians – collected data about the lives of these survivors and how they compared to peers who did not share this experience. The orientation of the book synthesizes several conceptual approaches – gerontological and life span development, stress research, and traumatology, and also reflects the varied disciplines of the authors, spanning psychology, social work, and sociology. The result is a multi-faceted view of their subject with an understanding of the individual, society, and the interaction of the two, tempered by the authors’ own Holocaust experiences. Chapters cover a range of areas including stress and coping of these survivors, reviews of their heath and mental health, an examination of their social integration, as well as a review of the multiple predictors of psychological well-being and adaptation to aging. This book will be of interest to psychologists, social workers, sociologists, psychiatrists, and all those who study both trauma and aging.

There has long been an interest in the effects of diet on mental health, and the interaction of the two with stress; however, the nature of these relationships is not well understood. Although ...associations between diet, obesity and the related metabolic syndrome (MetS), stress, and mental disorders exist, causal pathways have not been established.
We reviewed the literature on the relationship between diet, stress, obesity and psychiatric disorders related to stress.
Diet and obesity can affect mood through direct effects, or stress-related mental disorders could lead to changes in diet habits that affect weight. Alternatively, common factors such as stress or predisposition could lead to both obesity and stress-related mental disorders, such as depression and posttraumatic stress disorder (PTSD). Specific aspects of diet can lead to acute changes in mood as well as stimulate inflammation, which has led to efforts to assess polyunsaturated fats (PUFA) as a treatment for depression. Bidirectional relationships between these different factors are also likely. Finally, there has been increased attention recently on the relationship between the gut and the brain, with the realization that the gut microbiome has an influence on brain function and probably also mood and behavior, introducing another way diet can influence mental health and disorders. Brain areas and neurotransmitters and neuropeptides that are involved in both mood and appetite likely play a role in mediating this relationship.
Understanding the relationship between diet, stress and mood and behavior could have important implications for the treatment of both stress-related mental disorders and obesity.
The poultry industry plays a significant role in boosting the economy of several countries, particularly developing countries, and acts as a good, cheap, and affordable source of animal protein. A ...stress-free environment is the main target in poultry production. There are several stressors, such as cold stress, heat stress, high stocking density, and diseases that can affect birds and cause several deleterious changes. Stress reduces feed intake and growth, as well as impairs immune response and function, resulting in high disease susceptibility. These effects are correlated with higher corticosteroid levels that modulate several immune pathways such as cytokine-cytokine receptor interaction and Toll-like receptor signaling along with induction of excessive production of reactive oxygen species (ROS) and thus oxidative stress. Several approaches have been considered to boost bird immunity to overcome stress-associated effects. Of these, dietary supplementation of certain nutrients and management modifications, such as light management, are commonly considered. Dietary supplementations improve bird immunity by improving the development of lymphoid tissues and triggering beneficial immune modulators and responses. Since nano-minerals have higher bioavailability compared to inorganic or organic forms, they are highly recommended to be included in the bird’s diet during stress. Additionally, light management is considered a cheap and safe approach to control stress. Changing light from continuous to intermittent and using monochromatic light instead of the normal light improve bird performance and health. Such changes in light management are associated with a reduction of ROS production and increased antioxidant production. In this review, we discuss the impact of stress on the immune system of birds and the transcriptome of oxidative stress and immune-related genes, in addition, how nano-minerals supplementations and light system modulate or mitigate stress-associated effects.
Post-traumatic stress disorder (PTSD) is associated with elevated risk for a variety of age-related diseases and neurodegeneration. In this paper, we review evidence relevant to the hypothesis that ...chronic PTSD constitutes a form of persistent life stress that potentiates oxidative stress (OXS) and accelerates cellular aging. We provide an overview of empirical studies that have examined the effects of psychological stress on OXS, discuss the stress-perpetuating characteristics of PTSD, and then identify mechanisms by which PTSD might promote OXS and accelerated aging. We review studies on OXS-related genes and the role that they may have in moderating the effects of PTSD on neural integrity and conclude with a discussion of directions for future research on antioxidant treatments and biomarkers of accelerated aging in PTSD.
A comprehensive work that brings together and explores state-of-the-art research on the link between stress and health outcomes. Offers the most authoritative resource available, discussing a range ...of stress theories as well as theories on preventative stress management and how to enhance well-being Timely given that stress is linked to seven of the ten leading causes of death in developed nations, yet paradoxically successful adaptation to stress can enable individuals to flourish Contributors are an international panel of authoritative researchers and practitioners in the various specialty subjects addressed within the work
Plant hormones are signalling compounds that regulate crucial aspects of growth, development and environmental stress responses. Abiotic stresses, such as drought, salinity, heat, cold and flooding, ...have profound effects on plant growth and survival. Adaptation and tolerance to such stresses require sophisticated sensing, signalling and stress response mechanisms. In this Review, we discuss recent advances in understanding how diverse plant hormones control abiotic stress responses in plants and highlight points of hormonal crosstalk during abiotic stress signalling. Control mechanisms and stress responses mediated by plant hormones including abscisic acid, auxin, brassinosteroids, cytokinins, ethylene and gibberellins are discussed. We discuss new insights into osmotic stress sensing and signalling mechanisms, hormonal control of gene regulation and plant development during stress, hormone-regulated submergence tolerance and stomatal movements. We further explore how innovative imaging approaches are providing insights into single-cell and tissue hormone dynamics. Understanding stress tolerance mechanisms opens new opportunities for agricultural applications.
