A high corticosterone/DHEA-s ratio in young rats infected with Trypanosoma cruzi is associated with increased susceptibility

Memorias do Instituto Oswaldo Cruz, 2011
We have previously established that young male rats are more susceptible to the effects of Trypanosoma cruzi infection than adult rats. To explore underlying age-associated differences in disease outcome, we simultaneously assessed hormone levels and ...

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Hippocampal testosterone relates to reference memory performance and synaptic plasticity in male rats

Frontiers in Behavioral Neuroscience, 2010
Steroids are important neuromodulators influencing cognitive performance and synaptic plasticity. While the majority of literature concerns adrenal- and gonadectomized animals, very little is known about the natural endogenous release of hormones during ...

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Adrenal glands of Spix's yellow-toothed cavy (Galea spixii, Wagler, 1831): morphological and morphometric aspects

Brazilian Journal of Biology
Considering the physiological importance and need of greater morphophysiological knowledge of adrenal glands, the aims of present study were compare the morphometric data between left and right adrenal of male and female; perform a histological, scanning

Amygdala and ventromedial prefrontal cortex are inversely coupled during regulation of negative affect and predict the diurnal pattern of cortisol secretion among older adults [PDF]

, 2006
Among younger adults, the ability to willfully regulate negative affect, enabling effective responses to stressful experiences, engages regions of prefrontal cortex (PFC) and the amygdala.

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

Integrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

Renal‐vascular axis: unmasking its role in vascular endothelial growth factor‐inhibitor vascular toxicity in cancer patients

British Journal of Pharmacology, EarlyView.
Abstract Vascular toxicity is a growing concern in cancer patients receiving vascular endothelial growth factor inhibitor (VEGFi) therapy, posing a significant threat to patient prognosis. While the primary mechanism of VEGFi‐induced vascular toxicity is linked to redox‐sensitive reactions that disrupt vascular tone, leading to hypertension and ...
