Elevating Testosterone and Androstenedione Produces Temporary Sex‐Dependent Variation in Japanese Quail (Coturnix japonica) Embryonic Development

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Vertebrate growth rates may respond to maternally supplied steroids, yet injections of individual hormones into avian eggs of different species have produced inconsistent results. This might be because diverse steroids' concentrations are naturally correlated in yolks, injections are not elevating hormones at critical times in development, or ...

Cell Apoptosis and Glucocorticoid‐Induced Osteonecrosis

Med Research, EarlyView.
The review identifies glucocorticoid‐induced osteocyte/osteoblast apoptosis as central to femoral head osteonecrosis (GION), mediated through STAT1‐caspase‐3, PI3K/Akt, Wnt/β‐catenin, and oxidative stress pathways. Emerging therapies targeting these pathways (e.g., HIF‐1α stabilization, AMPK activation, and exosome‐mediated miRNA delivery) show ...

SPONTANEOUS-RECOVERY OF RATS FROM EXPERIMENTAL ALLERGIC ENCEPHALOMYELITIS IS DEPENDENT ON REGULATION OF THE IMMUNE-SYSTEM BY ENDOGENOUS ADRENAL CORTICOSTEROIDS [PDF]

, 1989
Experimental allergic encephalomyelitis (EAE) ' is a paralytic disease that can be induced in a number of animal species by evoking immune responses to antigens in central nervous system (CNS) myelin, and has been studied as a model for multiple ...

Non-breeding feather concentrations of testosterone, corticosterone and cortisol are associated with subsequent survival in wild house sparrows

Proceedings of the Royal Society B: Biological Sciences, 2012
Potential mechanistic mediators of Darwinian fitness, such as stress hormones or sex hormones, have been the focus of many studies. An inverse relationship between fitness and stress or sex hormone concentrations has been widely assumed, although ...

A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

Neuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.

Validating the underpinnings of water corticosterone measurement for aquatic amphibians [version 1; peer review: 2 approved]

F1000Research
Background Good animal welfare is important ethically but also to ensure animals provide valid scientific models. Despite thousands of amphibians in research laboratories there is minimal quantitative evidence pertaining to their management and welfare ...

Comparing plasma and faecal measures of steroid hormones in Adelie penguins Pygoscelis adeliae [PDF]

, 2010
Physiological measurements of both stress and sex hormones are often used to estimate the consequences of natural or human-induced change in ecological studies of various animals.

Biomimetic Approaches for Renewable Energy and Carbon Neutrality: Advancing Nature‐Inspired Approaches for Sustainable Development

Sustainable Development, EarlyView.
ABSTRACT As global non‐renewable energy sources depletes, achieving carbon neutrality by 2050 has become an urgent international priority, as outlined in the Paris Agreement. Renewable energy transition demands environmentally sustainable, economically viable, and energy‐efficient innovations.

AdipoRon Mitigates Anxiety and Depression Symptoms in Chronic Sleep-Restricted Mice via Modulation of Neuroinflammatory Responses. [PDF]

J Cell Mol Med
ABSTRACT The contemporary lifestyle has resulted in an epidemic of chronic sleep restriction (SR), which has emerged as a substantial contributor to mood disorders, particularly anxiety and depression. This study examined the effectiveness of AdipoRon (Adipo), a synthetic adiponectin agonist, in mitigating anxious behaviours and depression‐like ...

Baseline and stress-induced levels of corticosterone in male and female Afrotropical and European temperate stonechats during breeding [PDF]

, 2017
Background: Latitudinal variation in avian life histories falls along a slow-fast pace of life continuum: tropical species produce small clutches, but have a high survival probability, while in temperate species the opposite pattern is found.
