1. Ayahuasca prevents oxidative stress in a rat model of depression elicited by unpredictable chronic mild stress
ABSTRACT Background: Depression is a highly disabling common mental disorder and, due to its multifactorial nature, the development of effective therapies is challenging and of great relevance. Ayahuasca (AYA), an entheogenic traditional beverage, has emerged as an alternative for antidepressant treatment, however, AYA preclinical and clinical trials are st

Abstract Introduction Anhedonia is defined as the reduced ability to feel pleasure and is a core symptom of various psychiatric disorders such as depression and schizophrenia. The Snaith-Hamilton Pleasure Scale (SHAPS) was developed to assess the presence of anhedonia. The objective of this study was to assess the psychometric properties of the Brazilian P

3. Potential antidepressant effect of amantadine: a review of preclinical studies and clinical trials
Objective: Amantadine blocks N-methyl-D-aspartate (NMDA) receptors and has dopaminergic and noradrenergic action, a neurochemical profile that suggests its potential as an antidepressant drug. We conducted a systematic review of preclinical and clinical studies addressing the effects of amantadine in animal models of depression and in patients with depressi

7. Changes in tau phosphorylation levels in the hippocampus and frontal cortex following chronic stress
Studies have indicated that early-life or early-onset depression is associated with a 2- to 4-fold increased risk of developing Alzheimers disease (AD). In AD, aggregation of an abnormally phosphorylated form of the tau protein may be a key pathological event. Tau is known to play a major role in promoting microtubule assembly and stabilization, and in maint

8. Possible relations between Chronic Mild Stress (CMS) and operant performance / Possíveis inter-relações entre a submissão ao Chronic Mild Stree(CMS) e o desempenho operante
Chronic Mild Stress (CMS) é um modelo animal de depressão no qual ratos são submetidos a um protocolo de estressores moderados de forma crônica. Em função disso, o consumo e preferência por água com sacarose diminuem. Tal redução costuma ser considerada uma medida de anedonia, sintoma central da depressão em humanos. Três estudos realizados no La

9. The psychology and neuroscience of depression and anxiety: towards an integrative model of emotion disorders
Current theoretical models of emotion highlight the importance of distinguishing depression and anxiety. The present article critically evaluates a number of these models and provides a practical framework that could be applied in future studies to better understand the neural substrates that contribute to variation in anxiety and depressed mood. One influen

10. Um estudo sobre as possíveis interações entre o Chronic Mild Stress e o desempenho operante
Chronic Mild Stress-induced anhedonia is an animal experimental model that exposes rats to a mild stressors regime for a long period of time. This model was proposed in 1987 Willner, Towell, Sampson, Sophokleus e Muscat. The purpose of the present study was to verify whether the exposure of rats to an operate procedure when a concurrent schedule with equal F

12. Intracerebroventricular corticotropin-releasing factor increases limbic glucose metabolism and has social context-dependent behavioral effects in nonhuman primates
Corticotropin-releasing factor (CRF) is a neuropeptide involved in integrating the behavioral, autonomic, and hormonal responses to stress within the central nervous system. Patients suffering from depression have abnormal activity in stress responsive brain regions and elevated cerebrospinal fluid CRF. The DSM-IV criteria for major depressive disorder inclu
