The ethereal bodies of pro-Ana blogs: emotional communities and spaces of sociability on the web.

The study presented in this paper aimed at understanding how anorexic young women use virtual environments as spaces of sociability in order to construct a narrative about anorexia, anchor their experiences through emotional mutuality and validate discourses. To do so, an analysis of the content found in the commenting and posting sections of pro-anorexia blogs was carried out. Three thematic categories were identified: body, personal identity and sociability on the web.

Welfare Improvement by Enrichment Programs in Common Marmoset Females Under Social Isolation.

Animal welfare is critical to buffer stress in captive animals and to ensure the reliability of data from studies. The most usual environmental enrichment technique (EE) for social non-human primates is the social enrichment. However, some experimental protocols require keeping individuals isolated, thus demanding other types of EE.

Modulation of Serum Brain-Derived Neurotrophic Factor by a Single Dose of Ayahuasca: Observation From a Randomized Controlled Trial.

Serotonergic psychedelics are emerging as potential antidepressant therapeutic tools, as suggested in a recent randomized controlled trial with ayahuasca for treatment-resistant depression. Preclinical and clinical studies have suggested that serum brain-derived neurotrophic factor (BDNF) levels increase after treatment with serotoninergic antidepressants, but the exact role of BDNF as a biomarker for diagnostic and treatment of major depression is still poorly understood. Here we investigated serum BDNF levels in healthy controls ( = 45) and patients with treatment-resistant depression ( = 28) before (baseline) and 48 h after (D2) a single dose of ayahuasca or placebo.

Common Marmosets: A Potential Translational Animal Model of Juvenile Depression.

Major depression is a psychiatric disorder with high prevalence in the general population, with increasing expression in adolescence, about 14% in young people. Frequently, it presents as a chronic condition, showing no remission even after several pharmacological treatments and persisting in adult life. Therefore, distinct protocols and animal models have been developed to increase the understanding of this disease or search for new therapies.
