Maternal prenatal distress exposure negatively associates with the stability of neonatal frontoparietal network
In this study, we investigated the impact of prenatal distress on the spatial and temporal properties of functional networks detected in functional MRI data from 20 naturally sleeping, term-born (age 25.85 ± 7.72 days, 11 males), healthy neonates. First, we performed group level independent component analysis (GICA) to evaluate an association between PD and the spatial configuration of the functional networks. Second, we search for an association with PD at the level of the stability of functional networks over time using leading eigenvector dynamics analysis (LEiDA). No statistically significant associations were detecte...

The importance of the circadian trough in glucocorticoid signaling: a variation on B-flat
Stress. 2023 Oct 24:1-11. doi: 10.1080/10253890.2023.2275210. Online ahead of print.ABSTRACTGlucocorticoid hormones are essential for health, but overexposure may lead to many detrimental effects, including metabolic, psychiatric, and bone disease. These effects may not only be due to increased overall exposure to glucocorticoids, but also to elevated hormone levels at the time of the physiological circadian trough of glucocorticoid levels. The late Mary Dallman developed a model which allows the differentiation between the effects of overall 24-hour glucocorticoid overexposure and the effects of a lack of circadian rhythm...

Effects of chronic stress on bladder morphology of rats and impact of comfort food diet as an ameliorating agent
CONCLUSIONS: Chronic stress induces morphological modifications on the bladder wall and epithelium. These modifications may be related to lower urinary tract symptoms. Additionally, chronic stress caused a higher preference for comfort food intake which did not ameliorate or aggravate the stress-induced bladder alterations.PMID:37796089 | DOI:10.1080/10253890.2023.2265160 (Source: Stress)
