Long-term behavioral programming induced by peripuberty stress in rats is accompanied by GABAergic-related alterations in the amygdala

Maria del Carmen Sandi Perez, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence is a risk factor for psychopathology. Alterations in γ-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain, have been found following stress exposure and fear experiences and are often implica ...

CRHR1 links peripuberty stress with deficits in social and stress-coping behaviors

Maria del Carmen Sandi Perez, Orbicia Riccio Wicht, Vandana Veenit

Stressful life events during childhood and adolescence are important risk factors for the development of psychopathologies later in life. The corticotropin releasing hormone (CRH) and the CRH receptor 1 (CRHR1) have been implicated in the link between earl ...

Role of the HPA axis in the long-term programming of social behaviors by peripuberty stress

Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. In fact, exposure to stress during this period is known to predispose individuals to the development of psychopathologies such as depression and anxiety disorders l ...

The interplay of conditional NCAM-knockout and chronic unpredictable stress leads to increased aggression in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Orbicia Riccio Wicht, Céline Fournier

Abstract The neural cell adhesion molecule (NCAM) is a key regulator of brain plasticity. Substantial evidence indicates that NCAM is down-regulated by exposure to sustained stress and chronic stress seems to lead to increased aggression. In addition, cons ...

The Consequences of adolescent chronic unpredictable stress exposure on brain and behavior

Fiona Hollis

There is increasing evidence for adolescence as a time period vulnerable to environmental perturbations such as stress. What is unclear is the persistent nature of the effects of stress and how specific these effects are to the type of stressor. In this re ...

Testing nanomaterial toxicity in unicellular eukaryotic algae and fish cell lines.

Kristin Schirmer

Nanoecotoxicology as a sub-discipline of ecotoxicology aims to identify and predict effects elicited on ecosystems by nano-sized materials (NM). Two key groups of model organisms in this context are algae and fi sh. In this chapter, we present consideratio ...

Personality traits in rats predict vulnerability and resilience to developing stress-induced depression-like behaviors, HPA axis hyper-reactivity and brain changes in pERK1/2 activity

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Cristina Marquez Vega, Jorge Eduardo Castro Cifuentes, Shanaz Diessler

Emerging evidence indicates that certain behavioral traits, such as anxiety, are associated with the development of depression-like behaviors after exposure to chronic stress. However, single traits do not explain the wide variability in vulnerability to s ...

Elsevier2012

Adolescence is characterized by major developmental changes that may render the individual vulnerable to stress and the development of psychopathologies in a sex-specific manner. Earlier we reported lower anxiety-like behavior and higher risk-taking and no ...

Toxicokinetic-toxicodynamic modelling of survival of Gammarus pulex in multiple pulse exposures to propiconazole: model assumptions, calibration data requirements and predictive power

Kristin Schirmer

Toxicokinetic-toxicodynamic (TKTD) models quantify the time-course of internal concentration, which is defined by uptake, elimination and biotransformation (TK), and the processes which lead to the toxic effects (TD). TKTD models show potential in predicti ...

Ultra-low power hydrogen sensing based on a palladium-coated nanomechanical beam resonator

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Jonas Gustav Henriksson

Hydrogen sensing is essential to ensure safety in near-future zero-emission fuel cell powered vehicles. Here, we present a novel hydrogen sensor based on the resonant frequency change of a nanoelectromechanical clamped-clamped beam. The beam is coated with ...
