Induction of heme oxygenase-1 and adaptive protection against the induction of DNA damage after hyperbaric oxygen treatment.
2000
Hyperbaric oxygen (HBO) treatment of human subjects (i.e. exposure to 100% oxygen at a pressure of 2.5 ATA for a total period of 3 x 20 min) caused clear and reproducible DNA damage in lymphocytes, as detected with the comet assay (single cell gel electrophoresis). Induction of DNA damage was found only after the first HBO exposure and not after further treatments of the same individuals. Furthermore, blood taken 24 h after HBO treatment was significantly protected against the induction of DNA damage by hydrogen peroxide (H(2)O(2)) in vitro, indicating that adaptation occurred due to induction of antioxidant defenses. The cells were not significantly protected against the genotoxic effects …
Combining tDCS with prismatic adaptation for non-invasive neuromodulation of the motor cortex
2017
Abstract Background Prismatic adaptation (PA) shifts visual field laterally and induces lateralized deviations of spatial attention. Recently, it has been suggested that prismatic goggles are also able to modulate brain excitability, with cognitive after-effects documented even in tasks not necessarily spatial in nature. Objective The aim of the present study was to test whether neuromodulatory effects obtained from tDCS and prismatic goggles could interact and induce homeostatic changes in corticospinal excitability. Methods Thirty-four subjects were submitted to single-pulse transcranial magnetic stimulation (TMS) over the right primary motor cortex to measure Input-Output (IO) curve as a…
Corrective loops involved in fast aiming movements: effect of task and environment
1998
In daily living, we continuously interact with our environment. This environment is rarely stable and living beings show remarkable adaptive capacities. When we reach for an object, it is necessary to localize the position of this object with respect to our own body before programming an adequate arm movement. If the target remains stable, the programmed movement brings the hand near the target. However, what happens when the target suddenly jumps to another position in space? The aim of this work was to investigate how rapid aiming movements are corrected when the target is displaced close to movement onset. Our results reveal that rapid movements can be modified and that the efficiency of…
Coping with an acute psychosocial challenge: behavioral and physiological responses in young women.
2014
Despite the relevance of behavior in understanding individual differences in the strategies used to cope with stressors, behavioral responses and their relationships with psychobiological changes have received little attention. In this study on young women, we aimed at analyzing the associations among different components of the stress response and behavioral coping using a laboratory psychosocial stressor. The Ethological Coding System for Interviews, as well as neuroendocrine, autonomic and mood parameters, were used to measure the stress response in 34 young women (17 free-cycling women in their early follicular phase and 17 oral contraceptive users) subjected to the Trier Social Stress …
Integration of immigrants into a new culture is related to poor sleep quality.
2008
Abstract Background This article reports on the relationship between cultural influences on life style, coping style, and sleep in a sample of female Portuguese immigrants living in Germany. Sleep quality is known to be poorer in women than in men, yet little is known about mediating psychological and sociological variables such as stress and coping with stressful life circumstances. Migration constitutes a particularly difficult life circumstance for women if it involves differing role conceptions in the country of origin and the emigrant country. Methods The study investigated sleep quality, coping styles and level of integration in a sample of Portuguese (N = 48) and Moroccan (N = 64) im…
Emotional expression and coping style in female breast cancer.
2007
Background: The study of the relationship of emotional status and tumor etiology has been investigated in order to elaborate a multifactorial model able to provide an answer integrating the different disciplines on cancer. The aim of this work is to investigate the knowledge on the alexithymia construct, exploring the presence of such trait in women affected by mammary carcinoma and analyzing the used coping strategies. The study has also examined personal thoughts related to event control (locus of control). Method: The Toronto Alexithymia Scale, Coping Orientation to Problems Experienced, and Locus of Control questionnaires were administered to a group of 86 women aged 31-55 years (mean =…
Experiences of Patients With Breast Cancer of Participating in a Lifestyle Intervention Study While Receiving Adjuvant Chemotherapy
2017
Background Lifestyle interventions are suggested to reduce the symptom burden and comorbidities in patients with breast cancer and as an empowerment tool. However, undergoing chemotherapy is associated with low compliance to lifestyle recommendations. Importantly, few studies have documented the experiences of patients with breast cancer of participating in a comprehensive lifestyle intervention study while undergoing curative chemotherapy. Objective The aim of this study was to explore the experiences of patients with breast cancer of participating in an individualized comprehensive lifestyle intervention study focusing on diet, physical activity, mental stress management, and smoking cess…
Emotional suppression and breast cancer: validation research on the Spanish Adaptation of the Courtauld Emotional Control Scale (CECS).
2010
Emotional suppression has played an important role in the research on psychosocial factors related to cancer. It has been argued to be an important psychological factor predicting worse psychosocial adjustment in people with cancer and it may mediate health outcomes. The reference instrument in the research on emotional suppression is the Courtauld Emotional Control Scale (CECS). The present study analysed construct validity of a new Spanish adaptation of the CECS in a sample of 175 breast cancer patients. The results confirmed the proposal by Watson and Greer claiming that the CECS is composed of three subscales that measure different dimensions, but not independent, from emotional control…
Aspirations and wellbeing in Romanian and US undergraduates.
2011
Updating cross-cultural research of the past decade on the relationship between life aspirations and wellbeing, we compared Romanian (N=69) and US (N=64) undergraduates on the contribution of the importance and likelihood of attaining intrinsic and extrinsic aspirations to psychological maladjustment and life satisfaction, and on the qualitative meaning they assign to financial success. Similarly to prior studies, we found that extrinsic and intrinsic aspirations tended to be either negatively or positively correlated with life satisfaction, respectively; however, wealth predicted life satisfaction for Romanian students. Unlike previous research, we found generally negative relationships be…
Evidence for Human Adaptation and Foodborne Transmission of Livestock-Associated Methicillin-Resistant Staphylococcus aureus
2016
We investigated the evolution and epidemiology of a novel livestock-associated methicillin-resistant Staphylococcus aureus strain, which colonizes and infects urban-dwelling Danes even without a Danish animal reservoir. Genetic evidence suggests both poultry and human adaptation, with poultry meat implicated as a probable source.
