OBJECTIVE To categorize and describe the daily sources of stress encountered by HIV-infected women. METHODS Using a semi-structured questionnaire, 150 interviews were conducted among HIV-infected women who attended the Reference and Treatment Center for Sexually Transmitted Diseases and Aids in the state of São Paulo, Brazil, between July and December 1997. The studied variables were: demogra...

This study investigated whether the old adage “grin and bear it” has proven value by testing how covert and overt manipulation of facial expression influences affective and physiological responses to stress. One hundred and sixty-nine healthy college students were recruited for a “multitasking study,” which involved holding chopsticks in the mouth while simultaneously completing two stressful t...

The primary objective of this study was to examine a sample (n = 81) of HIV-positive incarcerated women to compare those with and those without a diagnosis of lifetime post-traumatic stress disorder (PTSD) with respect to demographics and legal, psychiatric, and health utilization histories. A secondary objective was to describe the prevalence of psychiatric disorders in the sample. Eighty-one ...

Introduction: Stress is a widespread problem and in Sweden many of the long-term sick are due to stress related causes. Discussions about how to reduce stress are present. Positive psychology offers one potential way to reduce stress. One intervention that has strong benefits is to know ones strengths of character, this has benefits both in reducing depression and stress as well as increasing w...

The theoretical model proposed by Berry and colleagues (Berry, 1997; Berry, Kim, Minde, & Mok, 1987) highlights the importance of identifying moderators in the acculturation process. Accordingly, the current study examined the Asian cultural value of family recognition through achievement (FRTA) and contingency of self-worth on academic competence (CSW-AC) as moderators in the association betwe...

We have induced a local conformational transition by positive torsional stress in small synthetic circular DNA molecules containing cruciforms with immobile or tetramobile branched junctions. The immobile species correspond to the extruded and intruded extrema of the tetramobile junction. Under normal conditions the sequences of all the branched species prevent them from being re-absorbed into ...

OBJECTIVE To examine the perioperative cardiac morbidity and mortality in patients undergoing major vascular surgery with beta-blockade after a positive stress test or cardiac catheterization. DESIGN Retrospective review of a quality assurance database. SETTING A university teaching hospital. PARTICIPANTS A consecutive series of 31 patients undergoing peripheral vascular or aortic surgery...

The current study assessed how negative and positive stress is related to dyspnea perception. The participants were 25 young women with a medical diagnosis of severe asthma, and 15 matched controls. Stress was induced during repeated rollercoaster rides. Results showed that negative emotional stress and blood pressure peaked just before, and positive emotional stress and heart beat peaked immed...

BACKGROUND Better understanding of acute stress responses is important for revision of DSM-5. However, the latent structure and relationship between different aspects of acute stress responses haven't been clarified comprehensively. Bifactor item response model may help resolve this problem. OBJECTIVE The purpose of this study is to develop a statistical model of acute stress responses, based...

The study of positive species interactions is a rapidly evolving field in ecology. Despite decades of research, controversy has emerged as to whether positive and negative interactions predictably shift with increasing environmental stress as hypothesised by the stress-gradient hypothesis (SGH). Here, we provide a synthesis of 727 tests of the SGH in plant communities across the globe to examin...
