Vasopressin, also known as arginine vasopressin or antidiuretic hormone, plays a pivotal role in maintaining body homeostasis. Increased vasopressin concentrations, measured by its surrogate copeptin, have been associated with disease severity as well as disease progression in polycystic kidney disease (PKD), and in experimental studies vasopressin has been shown to directly regulate cyst growt...
The preparation of tissue, the composition of the incubating media, and the analytical techniques used in this study have all been reported in previous publications from this laboratory (l-3). We are indebted to Professor V. duvigneaud for the generous supplies of the two purified neurohypophyseal hormones used in this study, oxytocin (ON-5) and arginine-vasopressin (AVN-3). The commercial vaso...
BACKGROUND Enhanced arginine vasopressin levels are associated with increased mortality during end-stage human heart failure, and cardiac arginine vasopressin type 1A receptor (V1AR) expression becomes increased. Additionally, mice with cardiac-restricted V1AR overexpression develop cardiomyopathy and decreased β-adrenergic receptor (βAR) responsiveness. This led us to hypothesize that V1AR sig...
BACKGROUND The control of airways reactivity is essential to our understanding of disease processes such as asthma. Many studies have examined the neural control of the airways, but more recently there has been evidence to show that the epithelium lining the airways may influence airways reactivity. METHODS Rabbit tracheal epithelial cells were dispersed with enzymes, grown in primary culture...
The role of endogenous arachidonic acid and its metabolites as mediators of cell growth was studied in rat mesangial cells. Inhibitors of the cytochrome P450 monooxygenase and lipoxygenase systems (nordihydroguaiaretic acid (NDGA), SK&F 525A, and ketoconazole) significantly reduced serum-stimulated cell growth as determined by cell counts and incorporation of [3H]thymidine. Inhibition of cycloo...
Several factors interact to maintain precise control of electrolyte transport in the mammalian cortical collecting duct. We have studied the effects of deoxycorticosterone, arginine vasopressin, and bradykinin on net transepithelial sodium and potassium transport in isolated, perfused rat cortical collecting ducts. Chronic administration of deoxycorticosterone to rats increased both sodium abso...
BACKGROUND Empathy improves our ability to communicate in social interactions and motivates prosocial behavior. The neuropeptides arginine vasopressin and oxytocin play key roles in socioemotional processes such as pair bonding and parental care, which suggests that they may be involved in empathic processing. METHODS We investigated how vasopressin and oxytocin affect empathic responding in ...
objective nocturnal enuresis is a common childhood problem and has various treatments. this study was carried out to compare oral and nasal vasopressin in the treatment of nocturnal enuresis in 5- to 12-year-old children who were referred to the shahid beheshti clinic in 2008. materials & methods this study included 100 children (62 males and 38 females) with nocturnal enuresis. one group (50 ...
The roles of the sympathetic nervous system, angiotensin II, and arginine vasopressin in the cardiovascular-renal responses to nitric oxide synthesis inhibition were examined in eight conscious dogs equipped with arterial and venous catheters and a nonoccluding bladder catheter. Nitric oxide inhibition was achieved by intravenous infusion of NG-nitro-L-arginine methyl ester (L-NAME) at 37.1 nmo...
