Acute and chronic alcohol modulation of extended amygdala calcium dynamics.

The central amygdala (CeA) and bed nucleus of the stria terminalis (BNST) are reciprocally connected nodes of the extended amygdala thought to play an important role in alcohol consumption. Studies of immediate-early genes indicate that BNST and CeA are acutely activated following alcohol drinking and may signal alcohol reward in nondependent drinkers, while stress signaling in the extended amygdala following chronic alcohol exposure drives increased drinking via negative reinforcement. However, the temporal dynamics of neuronal activation in these regions during drinking behavior are poorly understood.

Coagulation profiles during and after anabolic androgenic steroid use: data from the HAARLEM study.

Background: Anabolic androgenic steroids (AAS) are thought to increase venous thromboembolism (VTE) risk.

Objectives: We investigated whether AAS influence coagulation parameters associated with VTE by assessing their changes during and after AAS use.

Methods: The HAARLEM study enrolled 100 male amateur athletes voluntarily starting an AAS cycle between 2015 and 2018.

Subcortical serotonin 5HT receptor-containing neurons sex-specifically regulate binge-like alcohol consumption, social, and arousal behaviors in mice.

Binge alcohol consumption induces discrete social and arousal disturbances in human populations that promote increased drinking and accelerate the progression of Alcohol Use Disorder. Here, we show in a mouse model that binge alcohol consumption disrupts social recognition in females and potentiates sensorimotor arousal in males. These negative behavioral outcomes were associated with sex-specific adaptations in serotonergic signaling systems within the lateral habenula (LHb) and the bed nucleus of the stria terminalis (BNST), particularly those related to the receptor 5HT.
