Diurnal variations of hormonal secretion, alertness and cognition in extreme chronotypes under different lighting conditions

Jean-Louis Scartezzini, Apiparn Borisuit, Mirjam Münch, Lenka Maierova

Circadian rhythms in physiology and behavior are modulated by external factors such as light or temperature. We studied whether self-selected office lighting during the habitual waking period had a different impact on alertness, cognitive performance and h ...

No Scope for Social Modulation of Steroid Levels in a Year-Round Territorial Damselfish

Katarina Damjanovic

Both latitude and mating system have been proposed to shape relationships between steroid hormone levels and social behavior. Recently it has been postulated that species with long lasting non-seasonal territorial behavior have low androgen responsiveness. ...

Intestinal steroidogenesis controls PPAR expression in the colon and is impaired during ulcerative colitis

Johan Auwerx

Background and aims Immune tolerance breakdown during UC involves the peroxisome proliferator-activated receptor- (PPAR), a key factor in mucosal homoeostasis and the therapeutic target of 5-aminosalycilates, which expression is impaired during UC. Here we ...

Impact of HSD11B1 polymorphisms on BMI and components of the metabolic syndrome in patients receiving psychotropic treatments

Pierre Magistretti, Murielle Bochud, Aurélie Delacrétaz

Background Metabolic syndrome (MetS) associated with psychiatric disorders and psychotropic treatments represents a major health issue. 11 beta-Hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) is an enzyme that catalyzes tissue regeneration of active cor ...

Stress pulls us apart: Anxiety leads to differences in competitive confidence under stress

Maria del Carmen Sandi Perez, Samuel Bendahan, Fiona Hollis, John Christian Thoresen, Lorenz Goette

Social competition is a fundamental mechanism of evolution and plays a central role in structuring individual interactions and communities. Little is known about the factors that affect individuals’ competitive success, particularly in humans. Key factors ...

Imaging liver and brain glycogen metabolism at the nanometer scale

Anders Meibom, Graham Knott, Arnaud Comment, Stéphane Laurent Escrig, Yuhei Takado, Mojgan Masoodi

In mammals, glycogen synthesis and degradation are dynamic processes regulating blood and cerebral glucose-levels within a well-defined physiological range. Despite the essential role of glycogen in hepatic and cerebral metabolism, its spatiotemporal distr ...

Glucose-Sensitive QCM-Sensors Via Direct Surface RAFT Polymerization

Harm-Anton Klok, Caroline Sugnaux

Thin, phenylboronic acid-containing polymer coatings are potentially attractive sensory layers for a range of glucose monitoring systems. This contribution presents the synthesis and properties of glucose-sensitive polymer brushes obtained via surface RAFT ...

Endocrine Disrupting Compounds Affecting Corticosteroid Signaling Pathways in Czech and Swiss Waters: Potential Impact on Fish

Kristin Schirmer

This study investigated the occurrence of corticosteroid signaling disruptors in wastewaters and rivers in the Czech Republic and in Switzerland. 36 target compounds were detected using HPLC-MS/MS, with up to 6.4 mu g/L for azole antifungals that indirectl ...

Increased corticosterone in peripubertal rats leads to long-lasting alterations in social exploration and aggression

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. We have previously shown that subjecting male rats to stress during the peripubertal period induces long-lasting effects on emotion and social behaviors. As cortico ...

Role of the HPA axis in the long-term programming of social behaviors by peripuberty stress : behavioral, pharmacological and molecular approaches

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 ...

Progesterone/RANKL Is a Major Regulatory Axis in the Human Breast

Cathrin Brisken, Tamara Tanos, Georgios Sflomos, Ayyakkannu Ayyanan, Maryse Fiche, Maria Gutierrez Najera

Estrogens and progesterones are major drivers of breast development but also promote carcinogenesis in this organ. Yet, their respective roles and the mechanisms underlying their action in the human breast are unclear. Receptor activator of nuclear factor ...
