Introduction: The loss of nigrosome-1 which is also referred to as the swallow tail sign (STS) in T2* weighted iron-sensitive magnetic resonance imaging (MRI) has recently emerged as a new biomarker for idiopathic Parkinson’s disease (IPD). However, consistent recognition of the STS is difficult due to individual variations and different imaging parameters. Radiomics might have […]

Identifying older adults at risk for memory impairment is an important goal for initiating early treatment and prevention strategies. We examined the resting-state functional connectivity (RSFC) of older and younger adults before and after cognitive effort as a marker for subsequent memory decline, focusing on the connectivity between the left anterior hippocampus (laHC) and the […]

Current models suggest that low social status affects immune function by increasing inflammation and compromising antiviral defense. While this pattern appears to be somewhat conserved, recent studies argue that the gene regulatory signature of social status also depends on the local environment and the nature of social hierarchies.
