Bne29-011	miR-10a-5p as a critical molecular regulator of dopaminergic impulsivity in the nucleus accumbens
	Quote:	Among the differentially expressed miRs, miR-10a-5p emerged as the strongest candidate: it was constitutively elevated in high-impulsive rats and upregulated by PPX in low- and mid-impulsive animals in both regions, thereby paralleling the trait-dependent behavioral effect of the drug. In vivo viral-mediated overexpression of miR-10a-5p confirmed its predicted downregulation of the PI3KAKTmTOR and BDNF pathways in the striatum, and, critically, overexpression restricted to the NAcc, but not the dorsal striatum, was sufficient to increase impulsive choice, recapitulating the pro-impulsive effect of PPX. These findings identify miR-10a-5p as a critical molecular regulator of impulsivity through its activity in the NAcc, providing a mechanistic link between dopaminergic perturbation, trait vulnerability, and ICDs, and opening new avenues for the development of miR-directed therapeutic strategies for these disorders.

Mpy29-005	Revisiting the link between childhood adversity and stress-sensitive brain regions in psychosis and bipolar disorder: A systematic review and meta-analysis
	Quote:	Conclusion Childhood Aadversity was not consistently associated with hippocampal or amygdala volume alterations in PD and BD. More consistent evidence emerged for reduced GMV in prefrontal regions, suggesting that neurobiological impact of CA may be more robustly captured at the cortical level.

Mpy29-007	Prompt Engineering Limitations: Preliminary Evaluation of Large Language Models for Psychotherapy Safety
	Quote:	Models frequently validated harmful statements, colluded with hallucinations, minimized symptoms, or used stigmatizing language, including in the newest and largest models. These failures reflect structural limitations such as lack of memory, insufficient contextual reasoning, and training-related biases. Prompt engineering alone is therefore insufficient for safe AI-mediated psychotherapy; clinician-guided fine-tuning, integrated safety mechanisms, and system-level over-sight will be required. This work provides early evidence motivating deeper clinician-led evaluation and safety-oriented model development.
