Sustained corticosterone rise in the prefrontal cortex is a key factor for chronic stress-induced working memory deficits in mice

Neurobiology of Stress, 2019
Exposure to prolonged, unpredictable stress leads to glucocorticoids-mediated long-lasting neuroendocrine abnormalities associated with emotional and cognitive impairments.

Examining alterations in fGCM concentrations post‐defaecation across three animal feeding classes (ruminants, hindgut fermenters and carnivores)

Journal of Zoology, EarlyView.
This study examined changes in faecal glucocorticoid metabolite (fGCM) concentrations in nine species across three feeding classes (ruminants, hindgut fermenters and carnivores) over a 7‐day period to improve the accuracy of stress monitoring. Our findings revealed feeding class‐specific patterns, with herbivores showing a consistent decrease in fGCM ...

Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

Mammal Review, EarlyView.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Neurogenomic landscape associated with status‐dependent cooperative behaviour

Molecular Ecology, EarlyView.
Abstract The neurogenomic mechanisms mediating male–male reproductive cooperative behaviours remain unknown. We leveraged extensive transcriptomic and behavioural data on a neotropical bird species (Pipra filicauda) that performs cooperative courtship displays to understand these mechanisms.

Magnetic Resonance Imaging of Gastric Motility in Conscious Rats

Neurogastroenterology &Motility, EarlyView.
By training rats to remain awake inside an MRI scanner, we can now noninvasively scan their gastrointestinal tracts without using anesthesia. This allows us to assess gastric motility and emptying in conscious rats without the various confounding effects that anesthesia might cause.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Sedentary lifestyle induces oxidative stress and atrophy in rat skeletal muscle

Experimental Physiology, EarlyView.
Abstract Abundant evidence indicates that skeletal muscle plays a key role in regulating metabolic homeostasis. Therefore, maintaining healthy skeletal muscles is essential to good health. While prolonged muscle inactivity is known to cause oxidative stress and muscle loss, it remains unclear whether a shift from an active to a sedentary lifestyle ...
