The Role of Arginine Vasopressin in Alcohol Tolerance

Annals of Medicine, 1990
Administration of the neuropeptide, arginine vasopressin, to animals that have acquired functional tolerance to ethanol will maintain such tolerance, even in the absence of further ethanol ingestion by the animals. In mice, this action of the peptide is mediated by central nervous system V1 receptors and requires intact brain noradrenergic systems ...

Stress‐induced hyperphagia? Characterising the activity of the ghrelin axis in male rats with high anxiety behaviour

Journal of Neuroendocrinology, EarlyView.
Abstract While evidence is emerging that the temporal pattern of feeding may influence anxiety, it is unclear to what extent anxiety may itself impact spontaneous feeding behaviour. To address this, we have quantified spontaneous feeding, ghrelin secretion and adult hippocampal neurogenesis (AHN) in male low (LAB) and high (HAB) anxiety‐behaviour rats.

Nephrogenic diabetes insipidus (NDI): clinical, laboratory and genetic characterization of five Brazilian patients

Clinics, 2009
INTRODUCTION: Nephrogenic diabetes insipidus is characterized by a lack of response in the distal nephron to the antidiuretic hormone arginine vasopressin.

Epidemiology of acquired hypothalamic obesity following traumatic brain injury and nonspecific hypothalamic microinjury: A nationwide German claims data analysis

Journal of Neuroendocrinology, EarlyView.
Abstract Acquired hypothalamic obesity (aHO) is characterized by rapid and persistent weight gain resulting from structural or functional damage to the hypothalamus, typically accompanied by neuroendocrine dysfunction. While aHO is well described in the context of hypothalamic or suprasellar tumors, particularly craniopharyngioma, little is known about

Adaptation to harshness is fundamentally different from the adaptive stress response: Results from a 20‐year‐long case study in African striped mice

Journal of Zoology, EarlyView.
Animals in harsh environments rely on specialised adaptations. Two decades of field research on African striped mice (Rhabdomys pumilio) in the Succulent Karoo semi‐desert reveal a distinct ‘harshness response’—marked by reduced metabolism and glucocorticoid levels—that differs fundamentally from the classic stress response.

Morphofunctional Alterations of the Hypothalamus and Social Behavior in Autism Spectrum Disorders

Brain Sciences, 2020
An accumulating body of evidence indicates a tight relationship between the endocrine system and abnormal social behavior. Two evolutionarily conserved hypothalamic peptides, oxytocin and arginine-vasopressin, because of their extensively documented ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Multiphase management of sodium imbalance following traumatic brain injury: a case-based review

BMC Pediatrics
Background This review article discusses a case of sodium imbalance and fluid dysregulation in a patient with traumatic brain injury (TBI), progressing through phases including mannitol-induced osmotic diuresis, arginine vasopressin deficiency (central ...

Seven days of mixed‐method heat acclimation improved markers of cardiovascular and fluid‐regulatory strain during exercise‐heat stress

Experimental Physiology, EarlyView.
Abstract A mixed‐method heat acclimation (HA) protocol may optimise performance by supporting the training taper while promoting thermal adaptation; however, the impact on cardiovascular and fluid‐regulatory adjustments to protect health is unknown. Therefore, we examined the effects of a mixed‐method heat protocol on physiological responses, including

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

Experimental Physiology, EarlyView.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...
