Biological variation of arginine vasopressin

European Journal of Applied Physiology, 2020
There is growing interest in the measurement of plasma levels of arginine vasopressin (AVP) for the assessment of mild dehydration. However, the principles of biological variation have not been applied to the study of AVP and understanding biological variation of AVP may provide insights regarding measurement thresholds.

Measurement of Arginine Vasopressin

2013
Arginine vasopressin (AVP) is a peptide hormone synthesised in the hypothalamus and secreted from nerve terminals within the posterior pituitary gland. Secretion is primarily under osmoregulatory control and levels rise in plasma in response to a body water deficit and are suppressed in response to water overload.

Desamino-arginine-vasopressin, an analogue of arginine-vasopressin with high antidiuretic activity

Experientia, 1965
Die Synthese und die pharmakologischen Haupteigenschaften von Desamino2-Arginin-Vasopressin werden beschrieben. Dieses Peptid ist durch eine hohe (1300 IE/mg) und relativ selektive antidiuretische Wirksamkeit ausgezeichnet.

Circadian Variation of Plasma Arginine Vasopressin Concentration, or Arginine Vasopressin in Enuresis

Scandinavian Journal of Urology and Nephrology, 1999
The objective of these studies was to determine a relationship between primary nocturnal enuresis and arginine vasopressin (AVP) secretion. The first study compared 24-h AVP secretion profiles of enuretic (n = 9) and non-enuretic children (n = 8). Blood samples were collected at 1-h intervals for 24 h.

Carbamylation of Oxytocin and Arginine-Vasopressin

Nature, 1963
SYNTHETIC analogues of oxytocin and vasopressin in which the terminal amino group is absent or modified exhibit remarkable differences in biological activity. Whereas desamino-oxytocin is highly active1,2, analogues of oxytocin in which the amino group is substituted by acylation or alkylation retain little pharmacological activity3–5, and some act as ...

Arginine-vasopressin in essential hypernatremia

Journal of Endocrinological Investigation, 1986
Dynamics of AVP secretion in a 14-year-old girl with essential hypernatremia, psychomotor retardation and optic nerve coloboma, are reported. Basal levels of AVP were similar to those of a control population, but disproportionately low in relation with natremies.

HUMAN PLATELET ARGININE VASOPRESSIN

Clinical Endocrinology, 1986
SUMMARYApproximately 90% of arginine vasopressin circulating in blood is associated with the platelets. Studies in six patients with cranial diabetes insipidus indicate that the platelet vasopressin originates in the hypothalamus and is taken up from plasma.

Arginine vasopressin-Venus reporter mice as a tool for studying magnocellular arginine vasopressin neurons

Peptides, 2021
Arginine vasopressin (AVP) synthesized in the magnocellular neurons of the hypothalamus is transported through their axons and released from the posterior pituitary into the systemic circulation to act as an antidiuretic hormone. AVP synthesis and release are precisely regulated by changes in plasma osmolality.

Hypersecretion of Arginine Vasopressin in Acromegaly

The Journal of Clinical Endocrinology & Metabolism, 1971
ABSTRACT Four of 5 patients with untreated active acromegaly demonstrated prolonged antidiuresis and sustained release of arginine vasopressin (AVP) with nicotine stimulation of the neurohypophysis. This hyperresponsiveness was acutely suppressed by adrenal steroids in 2 subjects.

Enzyme immunoassay for arginine vasopressin

Experientia, 1982
A highly sensitive enzyme immunoassay for arginine vasopressin (AVP) was described. The enzyme used was β-D-galactosidase fromEscherichia coli, and it was coupled to AVP by using the N-hydroxysuccinimide ester of N-(4-carboxycyclohexylmethyl)-maleimide.
