Data from: Living in a high CO2 world: a global meta-analysis shows multiple trait-mediated responses of fish to ocean acidification
2018
Understanding how marine organisms will be affected by global change is of primary importance to ensure ecosystem functioning and nature contributions to people. This study meets the call for addressing how life-history traits mediate effects of ocean acidification on fish. We built a database of overall and trait-mediated responses of teleost fish to future CO2 levels by searching the scientific literature. Using a meta-analytical approach, we investigated the effects of projected CO2 levels by IPCC for 2050-2070 and 2100 on fish eco-physiology and behavior from 320 contrasts on 42 species, stemming from polar to tropical regions. Moreover, since organisms may experience a mosaic of carbon…
Data from: Carry-over effects of conditions at the wintering grounds on breeding plumage signals in a migratory bird: roles of phenotypic plasticity …
2016
To understand the consequences of ever-changing environment on the dynamics of phenotypic traits, distinguishing between selection processes and individual plasticity is crucial. We examined individual consistency/plasticity in several male secondary sexual traits expressed during the breeding season (white wing and forehead patch size, UV reflectance of white wing patch and dorsal melanin colouration) in a migratory pied flycatcher (Ficedula hypoleuca) population over an 11-year period. Furthermore, we studied carry-over effects of three environmental variables (NAO, a climatic index; NDVI, a vegetation index; and rainfall) at the wintering grounds (during pre-breeding moult) on the expres…
Social Entrepreneurship: Where to Go Next?
2021
This chapter summarizes the main conclusions of the micro perspective section. It revises the foundations of the social entrepreneurs and outlines a path for future avenues of social entrepreneurship. However, although the unit of analysis is the individual, this does not mean that it is an individual phenomenon. In fact, it can be considered as a widespread collective phenomenon, that is, the small initiative of a social entrepreneur at a local level can also be successfully replicated in other places around the globe. The social entrepreneur becomes himself through the influences and motivations of the environment, added to his innate and unique characteristics, these intrinsic motivation…
Reduction of Gender Identity Stigma and Improvements in Mental Health Among Transgender Women Initiating HIV Treatment in a Trans-Sensitive Clinic in…
2021
Purpose: Stigma toward transgender women (TGW) increases psychosocial vulnerability, leading to poor mental health and affecting access and retention in HIV care. Trans-sensitive health care (TSHC) has the potential to mitigate this adverse impact. This study aimed to describe baseline characteristics in gender identity stigma (GIS), mental health, and substance use among TGW living with HIV initiating antiretroviral treatment and to analyze changes after 6 months in HIV care in a TSHC clinic in Argentina. Methods: Sixty-one TGW living with HIV responded to the following questionnaires at baseline and after 6 months in TSHC: sociodemographic, experiences of GIS (in health care, police, etc.…
Frontal Electroencephalogram Alpha Asymmetry during Mental Stress Related to Workplace Noise
2021
This study aims to investigate the effects of workplace noise on neural activity and alpha asymmetries of the prefrontal cortex (PFC) during mental stress conditions. Workplace noise exposure is a pervasive environmental pollutant and is negatively linked to cognitive effects and selective attention. Generally, the stress theory is assumed to underlie the impact of noise on health. Evidence for the impacts of workplace noise on mental stress is lacking. Fifteen healthy volunteer subjects performed the Montreal imaging stress task in quiet and noisy workplaces while their brain activity was recorded using electroencephalography. The salivary alpha-amylase (sAA) was measured before and immedi…
A meta-analysis of temperament and character dimensions in patients with mood disorders: Comparison to healthy controls and unaffected siblings
2016
Background Cloninger's psychobiological model of personality has been extensively applied to subjects affected by mood disorders (MOOD). However, most studies are widely heterogeneous in terms of sample size, methods of assessment, and selection of participants. Methods We conducted a systematic review of literature and a random effects meta-analysis of studies comparing at least two of the following groups: (a) adults with a primary MOOD diagnosis (Bipolar Disorder (BP) or major depressive disorder (MDD)), (b) their unaffected siblings (SIB) or (c) healthy subjects (HS), and reporting quantitative results from the Tridimensional Personality Questionnaire (TPQ) or the Temperament and Charac…
The rorschach test evaluation in chronic childhood migraine: A preliminary multicenter case-control study
2017
Object Migraine headache prevalence ranges from 1.2 to 3.2% at 7 years of age, increasing with age up to 4-19% in adolescents.1 The aim of the present study is investigating the personality style associated with children and adolescent affected by Migraine without aura (MwA), through administration of the projective Rorschach test and statistical comparison with a group of age- and sex matched healthy controls. Methods 137 patients (74 males and 63 females), aged 7.3–17.4 years (mean age 11.4, SD 3.02 years), affected by MwA according to the IHs-3 criteria. The projective Rorschach test has been administrered to all the cases and controls. Statistical comparisons of groups were performed th…
Neurobiological and Clinical Variables Associated with Alcohol Abuse in Bulimia Nervosa
2015
The study was aimed at analysing the reciprocal relationships of several clinical and neurobiological items in order to predict alcohol misuse in patients with bulimia nervosa (BN). Seventy BN patients and 70 healthy controls were assessed for depression, impulsivity, borderline personality traits and self-defeating behaviours using specific scales; serum cortisol and 24-hour urinary excretion of serotonin and 5-hydroxiindolacetic acid were also assessed. The study confirmed the implications of these clinical factors for alcohol misuse in BN patients, but the results suggested that depressive symptoms and hypercortisolism could lie behind these relationships.
The crisis of psychiatry – insights and prospects from evolutionary theory
2012
Darwin’s emphasis on natural selection has had a transformative influence on how biological and medical sciences are conceptualized and conducted. However, the relevance of his ideas for the understanding of psychiatric conditions is still under-appreciated. Modern understanding of disease has required appreciation of the dialectical give and take between environmental influences, life history theory imperatives, human behavioral ecology, and characteristics of adaptive processes at all levels of the individual. This has enabled a better comprehension of metabolic disturbances, cancers, auto-immune disease, inherited anemias, and vulnerability to infectious disease 1. Here we propose that a…
Behavioral Traits Associated With Resilience to the Effects of Repeated Social Defeat on Cocaine-Induced Conditioned Place Preference in Mice
2020
The relationship between stress and drug use is well demonstrated. Stress-induced by repeated social defeat (RSD) enhances the conditioned place preference (CPP) induced by cocaine in mice. The phenomenon of resilience understood as the ability of subjects to overcome the negative effects of stress is the focus of increasing interest. Our aim is to characterize the behavior of resilient animals with respect to the effects of RSD on the CPP induced by cocaine. To this end, 25 male C57BL/6 mice were exposed to stress by RSD during late adolescence, while other 15 male mice did not undergo stress (controls). On the 2 days following the last defeat, all the animals carried out the elevated plus…
