N6 -Methyladenosine Modification in Chronic Stress Response Due to Social Hierarchy Positioning of Mice
2021
Appropriately responding to stressful events is essential for maintaining health and well-being of any organism. Concerning social stress, the response is not always as straightforward as reacting to physical stressors, e.g., extreme heat, and thus has to be balanced subtly. Particularly, regulatory mechanisms contributing to gaining resilience in the face of mild social stress are not fully deciphered yet. We employed an intrinsic social hierarchy stress paradigm in mice of both sexes to identify critical factors for potential coping strategies. While global transcriptomic changes could not be observed in male mice, several genes previously reported to be involved in synaptic plasticity, l…
Autonomic, hormonal, and subjective responses to a modified version of the TSST: a pilot study
2021
El objetivo de esta investigación fue estudiar las respuestas hormonales, autonómicas y afectivas a una versión modificada del estresor TSST en una muestra de jóvenes universitarios compuesta de treinta y ocho sujetos (11 hombres y veintisiete mujeres, 11 en la fase lútea del ciclo menstrual, 16 mujeres en la fase folicular). La respuesta hormonal se evaluó con niveles de cortisol. La frecuencia cardíaca y la actividad electrodérmica se registraron durante toda la sesión experimental y la ansiedad rasgo y estado se evaluaron antes y después de la tarea. La fase de discurso provocó la frecuencia cardíaca más alta, la mayor frecuencia de respuestas inespecíficas y el mayor nivel de conductanc…
Association between osteocalcin and cognitive performance in healthy older adults.
2016
INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
Decentering, Acceptance, and Non-Attachment : Challenging the Question "Is It Me?"
2021
Among mindfulness measures the three constructs acceptance, decentering, and non-attachment are psychometrically closely related, despite their apparent semantic differences. These three facets present robust psychometric features and can be considered core themes in most “third wave” clinical models. The aim of the present study was to explore the apparently different content domains (acceptance, decentering, and non-attachment) by administering various psychometric scales in a large sample of 608 volunteers. Resilience and depression were also assessed. Exploratory and confirmatory factor analyses performed in two randomly selected subsamples showed a bifactor approximation. The explained…
Participation and performance trends in ultra-triathlons from 1985 to 2009.
2011
International audience; We examined the changes in participation and performance trends in ultra-triathlons, from the Double Iron (7.6 km swimming, 360 km cycling, 84.4 km running) to the Deca Iron (38 km swimming, 1800 km cycling, 422 km running), between 1985 (first year of a Double Iron) and 2009 (25 years). The mean finish rate for all distances and races was 75.8%. Women accounted for ∼8-10% of the ultra-triathlons starters. For Double and Triple Iron, the number of finishers per year increased, from 17 to 98 and from 7 to 41, respectively. In the Deca Iron, the finishers per race have remained <20 since the first event was held, up to 2009. Concerning World best performances, the men …
The effects of a 10-week combined maximal and explosive strength and high-intesity endurance training period on neuromuscular performance and 3K time…
2015
Combined strength and endurance training has been noted to produce significant improvements in strength and endurance performances in both men and women. However, there seems to be moderate inhibitory effect regarding strength adaptations, especially considering power production. This study was conducted to investigate the effects of a 10-week combined maximal and explosive strength and high-intensity endurance training period on neuromuscular performance and 3K time-trial in males and females. A total of 19 healthy recreationally trained subjects (Males: M= 10, Females: F= 9) completed a 10-week combined strength and endurance training period. All subjects trained twice a week strength and…
La valorizzazione delle specificità femminili e maschili nelle pratiche scolastiche: problemi metodologico-didattici
2014
The need to partially distinguish a way to teach men and women is rooted in a philosophical anthropology that considers sex differences an enrichment. The strengthening of the sexual identity of the students and the acquisition of a proper gender identity, in a view of respecting people of the opposite sex and equal partnership, is one of the educational goals of the school. The school thus hypothesized becomes a laboratory in which everyone can build a personal identity.
Sex differences of anxiety disorders: Possible psychobiological causes - Diferencias entre hombres y mujeres en los trastornos de ansiedad: una aprox…
2009
Anxiety disorders are common in both men and women and are particularly disabling for the sufferer. Women of reproductive age are more vulnerable to developing these mental disorders than men; in fact their prevalence is 2-3 times higher among females than among males. Sex differences have also been reported in relation to the manifestation and expression of symptoms, the will to request medical or psychological assistance, the course of the disease, and even in the response to treatment. These sex differences may be attributable to multiple factors, such as genetic predisposition, anatomy, hormones and environment. However, very little is known about the risk factors for women with respect…
Decreased prevalence of left-handedness among females with male co-twins: Evidence suggesting prenatal testosterone transfer in humans?
2010
Studies of singletons suggest that right-handed individuals may have higher levels of testosterone than do left-handed individuals. Prenatal testosterone levels are hypothesised to be especially related to handedness formation. In humans, female members from opposite-sex twin pairs may experience elevated level of prenatal exposure to testosterone in their intrauterine environment shared with a male. We tested for differences in rates of left-handedness/right-handedness in female twins from same-sex and opposite-sex twin pairs. Our sample consisted of 4736 subjects, about 70% of all Finnish twins born in 1983–1987, with information on measured pregnancy and birth related factors. Circulatin…
Sex Differences in Severity of Stroke in the INSTRUCT Study: a Meta‐Analysis of Individual Participant Data
2018
Background Women have worse outcomes after stroke than men, and this may be partly explained by stroke severity. We examined factors contributing to sex differences in severity of acute stroke assessed by the National Institutes of Health Stroke Scale. Methods and Results We pooled individual participant data with National Institutes of Health Stroke Scale assessment (N=6343) from 8 population‐based stroke incidence studies (1996–2014), forming part of INSTRUCT (International Stroke Outcomes Study). Information on sociodemographics, stroke‐related clinical factors, comorbidities, and pre‐stroke function were obtained. Within each study, relative risk regression using log‐binominal modeling…
