Output from VIP cells of the mammalian central clock regulates daily physiological rhythms [PDF]

, 2020
The suprachiasmatic nucleus (SCN) circadian clock is critical for optimising daily cycles in mammalian physiology and behaviour. The roles of the various SCN cell types in communicating timing information to downstream physiological systems remain ...

Interdigitale Aptamer‐Sensoren mit komplementären Messkanälen zur schnellen Detektion kleiner Moleküle in Biofluiden

Angewandte Chemie, EarlyView.
Ein elektrochemischer Aptamer‐Sensorchip nutzt Interdigitalelektroden mit selektiver Monoschicht‐Funktionalisierung, um Dopamin und Cortisol mittels robuster komplementärer „Signal‐Off/On“‐Antworten zu detektieren. Diese Dual‐Channel‐Signalumwandlung ermöglicht eine schnelle Detektion innerhalb von 5–30 min bei geringen Probenvolumina in künstlicher ...

Assessment of testicular corticosterone biosynthesis in adult male rats.

PLoS ONE, 2015
Corticosterone is synthesized in the adrenal glands and is circulated throughout the body to perform regulatory functions in various tissues. The testis is known to synthesize and secrete testosterone and other androgens.

Comparison of Corticosterone Concentrations in Dermal Secretions and Urine in Free-Ranging Marine Toads (Rhinella marina) in Human Care

Veterinary Medicine International, 2023
Corticosterone concentrations have been measured in amphibians by collecting blood or urine samples. However, blood sampling is invasive, and urine can be difficult to collect.

Glucocorticoid Receptor and Adipocyte Biology. [PDF]

, 2018
Glucocorticoids are steroid hormones that play a key role in metabolic adaptations during stress, such as fasting and starvation, in order to maintain plasma glucose levels.

Dual‐Channel Interdigitated Aptamer‐Based Sensors for Rapid Small‐Molecule Detection in Biofluids

Angewandte Chemie International Edition, EarlyView.
An electrochemical aptamer sensing chip employs dual interdigitated electrodes and selective self‐assembled monolayer removal to convert small‐molecule recognition into robust “signal‐off/on” responses. This dual‐channel signal conversion minimizes background noise and accelerates probe diffusion, enabling rapid (as fast as 5–30 min), low‐volume ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Chronic treatment with glucocorticoids does not affect egg quality but increases cortisol deposition into egg albumen and elicits changes to the heterophil to lymphocyte ratio in a sex-dependent manner

Frontiers in Physiology, 2023
During chronic stress, there is an initial increase in glucocorticoid (GC) levels, but they then return to low, albeit not baseline, levels. Recent studies have renewed interest in cortisol in that it may also have important roles in the stress response.

KREO Prevents CUMS-Induced Depressive-Like Behavior via Modulation of the BDNF Signaling Pathway. [PDF]

Food Sci Nutr
This study showed that Chinese Kushui Rose Essential Oil (KREO) can alleviate depressive symptoms, increase voluntary activity, and enhance exploratory behavior in mice induced with chronic unpredictable mild stress (CUMS) by elevating serotonin (5‐HT) levels and reducing hyperactivity of the hypothalamic–pituitary–adrenal (HPA) axis.

Microbial lysate upregulates host oxytocin [PDF]

, 2017
Neuropeptide hormone oxytocin has roles in social bonding, energy metabolism, and wound healing contributing to good physical, mental and social health. It was previously shown that feeding of a human commensal microbe Lactobacillus reuteri (L.
