An adaptive display for the treatment of diverse trauma PTSD victims.

2009

El trastorno de estrés postraumático (TEPT) puede desarrollarse después de la exposición a un evento aterrador. Las personas que sufren de trastorno de estrés postraumático presentan hiperactividad y evitación, y experimentan síntomas que provocan angustia y deterioro en áreas de vida significativas. Los programas de comportamiento cognitivo, incluida la terapia de exposición, son actualmente el tratamiento de elección para el TEPT. Aunque estos programas son eficaces, hay margen de mejora; La utilización de la terapia de exposición por los médicos es baja y las tasas de desgaste son altas. La aplicación de nuevas tecnologías, especialmente la realidad virtual (VR), podría ayudar a superar …

Association between diabetes and stroke subtype on survival and functional outcome 3 months after stroke: data from the European BIOMED Stroke Projec…

2004

To the Editor: Regarding the study by Megherbi et al1 performed to evaluate stroke features, prognosis, and functional outcome in patients with diabetes compared with patients without diabetes, we would like to discuss some issues of potential interest: First, the authors analyzed diabetic patients classified in accordance with WHO diagnostic criteria for diabetes used in 1993 (fasting plasma glucose >140 mg/dL), so it is probably an underestimation of the number of diabetic subjects in the 4537 consecutive patients with ischemic stroke enrolled. Perhaps if they could have classified diabetic patients in accordance with American Diabetes Association (1997)2 criteria (fasting plasma glucose …

Deciliation: A stressful event for Paracentrotus lividus embryos.

1998

In this report, by using mono- and two-dimensional electrophoretic analysis, we demonstrate that deciliation on sea urchin embryos induces a stress response. Deciliation indeed causes not only the activation of ciliary subroutine, but also a transient decrease of bulk protein synthesis. This decrease is in agreement with our previous results on heat shock response in sea urchin, although deciliation does not induce the expression of the same main hsp set. We were able to characterize one main deciliation-stress protein of 40 kDa whose expression is transiently induced by deciliation and whose localisation is likely to be nuclear.

Effect of epicentral direction on seismic response of asymmetric buildings

1984

The paper deals with the influence of the epicentral direction on the displacement and stress response of multistorey asymmetric buildings to earthquake horizontal ground motion. A method is given for computing for each plane frame of the complex structure a particular direction of the bidirectional stationary random input for which the horizontal floor displacement of the given frame is maximized. It is shown that this direction can be considered conservative for the corresponding non-stationary process.

Work-Related Stress, Physio-Pathological Mechanisms, and the Influence of Environmental Genetic Factors

2019

Work-related stress is a growing health problem in modern society. The stress response is characterized by numerous neurochemicals, neuroendocrine and immune modifications that involve various neurological systems and circuits, and regulation of the gene expression of the different receptors. In this regard, a lot of research has focused the attention on the role played by the environment in influencing gene expression, which in turn can control the stress response. In particular, genetic factors can moderate the sensitivities of specific types of neural cells or circuits mediating the imprinting of the environment on different biological systems. In this current review, we wish to analyze …

Stress response in Drosophila subobscura. II. Puff activity during anoxia and recovery from anoxia.

1987

When individuals of Drosophila subobscura at 0 hr prepupa are submitted to anoxia (4 hr and 24 hr, respectively), their puffing pattern is very similar to that shown by individuals at the moment of development in which treatment began. The same expression of genes (the same puffing pattern and the same protein pattern) is induced in this species by recovery from anoxia as well as by heat shock treatment at 31 degrees C.

Investigating individual stress reactivity: High hair cortisol predicts lower acute stress responses

2020

Identifying individual differences in stress reactivity is of particular interest in the context of stress-related disorders and resilience. Previous studies already identified several factors mediating the individual stress response of the hypothalamus-pituitary-adrenal axis (HPA). However, the impact of long-term HPA axis activity on acute stress reactivity remains inconclusive. To investigate associations between long-term HPA axis variation and individual acute stress reactivity, we tested 40 healthy volunteers for affective, endocrine, physiological, and neural reactions to a modified, compact version of the established in-MR stress paradigm ScanSTRESS (ScanSTRESS-C). Hair cortisol con…

Behaviour of salivary testosterone and cortisol in men during an Ironman Triathlon

2021

Endurance exercise induces notable acute hormonal responses on the gonadal and adrenal hormones. The purpose of this study was to assess the changes in salivary testosterone (Ts), salivary cortisol (Cs) and T/C ratio during long-distance triathlon. Ten well-trained male triathletes participated in the study and were assessed for hormonal changes at four time-points (pre-competition, post-swimming, post-cycling, and post-running phases). Ts decreased from pre-competition to post-swimming (from 93.37 pg/mL to 57.63 pg/mL; p < .01) and increased during two other parts of the competition to almost pre-competition values (cycling: 79.20 pg/mL, p = .02; running: 89,66 pg/mL, p = .04, respectively…

How are neuroticism and depression related to the psychophysiological stress response to acute stress in healthy older people?

2015

Neuroticism and depressive symptomatology have been related to a heightened and diminished physiological stress response, which may partly explain their negative relationship with health and wellbeing. Identifying factors that may increase disease vulnerability is especially relevant in older people, whose physiological systems decline. With this in mind, we investigated the influence of neuroticism and depression on the psychophysiological stress response in healthy older people (from 55 to 76years old). A total of 36 volunteers were exposed to a stressful task (Trier Social Stress Test, TSST), while 35 volunteers performed a control non-stressful task. The physiological stress response wa…
