High- and Low-conditioned Behavioral effects of midazolam in Carioca high- and low-conditioned freezing rats in an ethologically based test

Publication date: 10 January 2020Source: Neuroscience Letters, Volume 715Author(s): Daniele Rodrigues Cavaliere, Silvia Maisonnette, Thomas E. Krahe, J. Landeira-Fernandez, Antonio Pedro Mello CruzAbstractThe selective breeding of laboratory rodents with different anxiety-related traits is the subject of growing interest. The present study compared the effects of the benzodiazepine midazolam in the elevated plus maze (EPM) test of anxiety in two lines of Wistar rats that were selectively bred in our laboratory for either high or low anxiety-like traits based on a contextual freezing conditioning paradigm. After phenotyping anxiety-like traits (i.e., conditioned freezing behavior), Carioca High-Freezing [CHF], Carioca Low-Freezing [CLF]) and control rats were intraperitoneally injected (1.0 ml/kg) with .9 % saline or midazolam (.25, .5, .75, and 1.0 mg/kg) and subjected to the EPM 30 min later. After the saline injection, the CHF and CLF groups exhibited lower and higher open-arm exploration in the EPM, respectively, compared with control rats. These results indicate that anxiety-related traits previously selected from an associative learning paradigm can also be phenotypically expressed in an ethologically based animal model of anxiety. All midazolam doses significantly increased open-arm exploration in both CHF and control animals, but this anxiolytic-like effect in CLF rats was only observed at the lowest dose tested (.25 mg/kg). The present findings indicate that t...

Publication date: Available online 18 January 2020Source: Journal of Anxiety DisordersAuthor(s): Jennifer L. Buchholz, Jonathan S. AbramowitzAbstractThe therapeutic alliance has been the subject of a great deal of psychotherapy research, and evidence from numerous empirical studies suggests that a strong patient-therapist relationship predicts favorable treatment outcomes. Despite the consistency of the alliance outcome relationship across treatment modalities and diagnoses, little attention has been given to this potential prognostic indicator in exposure therapy for anxiety-related disorders. Given that exposure therapy ...

This review aims to clarify under which conditions socially anxious individuals display visual avoidance of faces. Through a systematic search in Web of Science and PubMed up to March 2019 we identified 61 publications that met the inclusion criteria. We discuss the influence of three factors on the extent to ...

This study aimed to investigate the relationship between parent and child anxiety levels and child autism characteristics on the four domains of family accommodation; Participation, Modification, Distress, and Consequence. A community sample (n = 132) of parents of children on the spectrum completed questionnaires on their child’s autism characteristics and anxiety symptomatology as well as their own levels of anxiety and family accommodation behaviours. Regression models identified specific aspects of child anxiety as well as parent anxiety as predictive of family accommodation, with the child’s ...

To our knowledge, no one has studied the ketogenic diet in any fragile X syndrome (FXS) model. FXS is the leading known genetic cause of autism. Herein, we tested the effects of chronic ketogenic diet treatment on seizures, body weight, ketone and glucos...

ConclusionThis is one of the first studies to examine subcortical morphology of basal ganglia and thalamic regions related to StD in adolescents, and the first study to report mostly positive associations between StD, volume and outward morphology in youths. These findings could reflect intact neurogenesis or resilience to depression, however longitudinal research is needed to further understand the neurobiology of StD in adolescents.
