The purpose of this study was to predict secondary traumatic stress and post-traumatic growth based on cognitive emotion regulation in nurses providing services to earthquake victims in Kermanshah. Methods: The present study is a descriptive-correlat...
The systemic elevation of psychological stress-induced glucocorticoids strongly suppresses CD8(+) T cell immune responses resulting in diminished antiviral immunity. However, the specific cellular targets of stress/glucocorticoids, the timing of exposure, the chronology of immunological events, and the underlying mechanisms of this impairment are incompletely understood. In this study, we addre...
The survival of naïve T cells is believed to require signals from TCR-pMHC interactions and cytokines such as IL-7. In contrast, signals that negatively impact naïve T cell survival are less understood. We conducted a forward genetic screening of mice and found a mutant mouse line with reduced number of naïve T cells (T-Red mice). T-Red mice have a point mutation in the Kdelr1 gene, and their n...
Background & Aim: Infant hospitalization in the intensive care unit is stressful for parents so that it affects their parental role. Nurses, due to their special situation, can play an important role in reducing parental stress. This study aimed to determine the effect of parental role training by a nurse on stress in the parents of hospitalized newborns in a neonatal intensive care unit. Meth...
T cells are used in many cell-based cancer treatments. However, oxidative stress that is induced during various chronic inflammatory conditions, such as cancer, can impair the immune system and have detrimental effects on T cell function. In this study, we have investigated the sensitivity of different human T cell subsets to H(2)O(2)-induced oxidative stress. We showed that central memory (CD4...
Thymus with more than 200 species is known for its medicinal and culinary uses. There is an increasing demand for thyme and its products, requiring cultivation under different conditions, including drought. To understand the response of thyme to water deficit and its variation across the genus, eleven populations from a range of species (Thymus daenensis, T. kotchyanous, T. vulgaris, T. serpyll...
Background and objective: In the nursing profession, there are numerous factors which altogether cause occupational stress and as a result occupational exhaustion in nurses and decrease the quality of patient care. Regarding the importance of this issue which influences the health indices of the society, this study investigates the effect of progressive muscle relaxation on the occupational str...
Background & Aims: Considering the important role of stress in intensifying gastroesophageal reflux disease (GERD) symptoms, the aim of the present study was to determine the effectiveness of stress management training in reducing symptoms in patients with GERD. Methods: In the present semi-experimental study, a pre-test post-test design with control group was used. From among the patients who ...
background: hospitalization in neonatal intensive care unit (nicu) leads to a lot of stress and shock to the parents. nurses, as the primary sources of information, could play an important role in reducing their stress. the aim of this study was to determine the effect of educational program on the premature infants’ parental stress in nicu. methods: this double-blind randomized controlled tria...
PURPOSE To evaluate the effectiveness of Prime Time Sister Circles (PTSC), a curriculum-based, culture- and gender-specific health intervention, in assisting mid-life African-American women to decrease the major risk factors of physical inactivity, poor nutrition and stress. METHODS One-hundred-thirty-four African-American women were involved in 11 sites across the country in PTSC and compari...
