Vasopressin as a neuroendocrine regulator of anterior pituitary hormone secretion

, 1993
Secretion of the anterior pituitary hormones adrenocorticotropin (ACTH), β-endorphin and prolactin (PRL) is complex and involves a variety of factors. This review focuses on the involvement of arginine-vasopressin (AVP) in neuroendocrine regulation of ...

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

The Enteric Nervous System: An Integrative Hub From Development to Systemic Physiology

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Unlike a static hardwired circuit, the ENS continuously remodels its transcriptional programs and synaptic connectivity in response to three ecological forces: microbial metabolites, immune cell signals and enteroendocrine cues. ABSTRACT The enteric nervous system (ENS) constitutes the largest and most functionally autonomous subdivision of the ...

Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...

Occurrence of rare somatomammotrophs in ovine anterior pituitary tissue studied by immunogold labelling and electron microscopy

, 1990
Prolactin and GH are distinct hormones that have been conventionally thought to be produced and secreted by separate cells in the anterior pituitary gland. Recently it has been suggested that some cells (somatomammotrophs) may secrete both hormones.

Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...

Personalized multimodal physiological modeling of menstrual cycle dynamics using endocrine, metabolic and wearable signals

Journal of Intelligent Medicine, EarlyView.
Abstract Menstrual cycle tracking remains challenged by the limited physiological scope and inconsistent generalizability of existing wearable‐based approaches, which often rely on individual sensing modalities that incompletely capture the complexity of menstrual physiology.

The Impact of Pregnancy on the Course of Vitiligo—A Systematic Review

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Vitiligo is a chronic autoimmune skin disorder affecting an estimated 0.36% of the global population. Previous research indicated an interaction between pregnancy and autoimmunity disorders. However, evidence regarding the interaction between pregnancy and vitiligo is limited. A better understanding of the impact of pregnancy on the

Paediatric Melanonychia: Diagnosis and Management

JEADV Clinical Practice, EarlyView.
ABSTRACT Longitudinal melanonychia (LM) in children presents unique diagnostic and management challenges that cannot be adequately addressed by applying adult‐based criteria. Unlike in adults, there are no validated clinical, dermoscopic or histopathologic criteria for predicting nail unit melanoma in the paediatric population.
