Unveiling sleep disturbances in KCNB1‐related disorders: Insights from a cohort of 78 individuals

Epilepsia Open, EarlyView.
Abstract Objectives Sleep disturbances are frequent comorbidities in epilepsies and developmental encephalopathies. This study aimed to characterize sleep abnormalities in individuals with KCNB1‐related disorders, focusing on their prevalence, clinical manifestations, and impact on daily functioning.

Stress response of fire salamander larvae differs between habitat types

Royal Society Open Science
The larvae of the European fire salamander (Salamandra salamandra) can inhabit two different habitats: streams and ponds. Streams are characterized by lower predation risks and higher food availability. Thus, ponds are considered a less suitable habitat.

Bile acid metabolism and signaling in human and animal health: A One Health perspective

iMetaOmics, EarlyView.
Bile acids maintain host homeostasis through enterohepatic circulation, microbial transformation, and bile acid receptor signaling, thereby regulating glucose and lipid metabolism, intestinal barrier integrity, and immunity. These effects support human disease intervention and health‐oriented animal production, reducing drug dependence and residue ...

Acute and chronic glucocorticoid treatments regulate astrocyte-enriched mRNAs in multiple brain regions in vivo

Frontiers in Neuroscience, 2013
Previous studies have primarily interpreted gene expression regulation by glucocorticoids in the brain in terms of impact on neurons; however, less is known about the corresponding impact of glucocorticoids on glia and specifically astrocytes in vivo ...

Corticosterone Induces Depressive-Like Behavior in Female Peri-Pubescent Rats, but Not in Pre-Pubescent Rats

Chronic Stress, 2020
Background There are no data on the effect of exogenous corticosterone on depressive-like behavior in juvenile rats. Furthermore, it has not been tested whether the effects of corticosterone in female rats is different before or after puberty.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Corticosterone enhances the potency of ethanol against hippocampal long-term potentiation via local neurosteroid synthesis

Frontiers in Cellular Neuroscience, 2015
Corticosterone is known to accumulate in brain after various stressors including alcohol intoxication. Just as severe alcohol intoxication is typically required to impair memory formation only high concentrations of ethanol (60mM) acutely inhibit long ...

Research Note: Quantifying corticosterone in turkey (Meleagris gallopavo) feathers using ELISA

Poultry Science, 2020
The measurement of corticosterone in feathers is an appealing tool for assessing glucocorticoids in wild and domestic bird species. Feather corticosterone measurements can be performed noninvasively and can provide a means for comparing glucocorticoid ...

The Role of Corticosterone Rhythmicity in Puberty [PDF]

Biology of Reproduction, 1976
To establish the functional importance of a peripheral rhythm of corticosterone in the timing of the onset of vaginal opening and ovulation, rats were adrenalectomized at 22 days of age and maintained on either saline or corticosterone (B) dissolved in their drinking water.

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile
