This study found that individuals with the AG/GG genotype of the A118G SNP in the OPRM1 gene experienced more pleasant and fewer unpleasant effects from hydromorphone compared to those with the AA genotype, suggesting genotype-based differences in opioid sensitivity. Highlights: Positive Effects: Participants with the AG/GG genotype reported significantly more positive effects (e.g., good effects, …
CYP2C19 poor metabolizers showed a nominally higher antidepressant remission rate compared to normal metabolizers, but overall genetic variations in CYP2C19 and CYP2D6 were not significantly associated with antidepressant response. Highlights: Higher Remission Rate: CYP2C19 poor metabolizers had a nominally higher remission rate (OR = 1.46) compared to normal metabolizers, but this did not hold after …
A new neuroimaging study has uncovered associations between subclinical narcissistic traits and regional grey matter volumes in the brain, specifically in the insular cortex and multiple prefrontal regions. The research, conducted by scientists at the University of Jena in Germany, provides novel evidence that narcissistic personality tendencies are linked to structural variations in brain networks …
