Comparison of natural and artificial vasopressin deficiency: why the latter is lethal?

open access: yesВавиловский журнал генетики и селекции, 2016
The transgenic mouse technology is widespread, however, untill now 22.0 % of tested null mutations was found to be lethal. The complete lack of vasopressin (AVP) resulted also in preweaning lethality.

Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol

open access: yesAngewandte Chemie, EarlyView.
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).

A case of pheochromocytoma crisis with persistent hypotension successfully managed with vasopressin

open access: yesUrology Case Reports, 2021
We report the first case of pheochromocytoma crisis with hypotension that was successfully treated with vasopressin. A 64-year-old patient was diagnosed as pheochromocytoma crisis.

Metabolic effects of vasopressin in pathophysiology of diabetic kidney disease

open access: yesFrontiers in Endocrinology, 2023
The diabetic kidney disease (DKD) is the major cause of the chronic kidney disease (CKD). Enhanced plasma vasopressin (VP) levels have been associated with the pathophysiology of DKD and CKD.

Blockade of vasopressin receptors reduces the threshold pressure of micturition reflex in female rats

open access: yesCurrent Research in Physiology, 2022
The mechanisms involved in urinary bladder control are not fully understood, but it is well accepted that a complex central network is involved in micturition control.

Vasopressin receptor-mediated endocytosis in cells transfected with V1-type vasopressin receptors

open access: yesKidney International, 1993
We examined the process of receptor-mediated endocytosis in A-9 lung fibroblast and chinese hamster ovary (CHO) cells transfected with the recently cloned vasopressin V1a receptor (51). We used a fluorescent labeled vasopressin analog (rhodamine-mercaptopropionic acid lysine vasopressin) and radiolabeled vasopressin to examine this process in the two ...

Hyponatremia, Arginine Vasopressin Dysregulation, and Vasopressin Receptor Antagonism [PDF]

open access: yesAmerican Journal of Nephrology, 2006
Hyponatremia is often associated with arginine vasopressin (AVP) dysregulation that is regulated by the hypothalamo-neurohypophyseal tract in response to changes in plasma osmolality, commonly in patients with the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Extracorporeal Catalytic Hemoperfusion Therapy for Refractory Septic Shock Using Ceria Nanoparticle‐Embedded Porous Microbeads

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces an extracorporeal hemoperfusion system incorporating porous microbeads embedded with autocatalytic ceria nanoparticles (CeNPs) for targeted reactive oxygen species (ROS) scavenging in septic shock. The blood‐compatible hemoperfusion cartridge demonstrated significant improvements in survival, hemodynamic stability, and organ ...

Physiopathology of hereditary polyuric states: a molecular view of renal function

open access: yesSwiss Medical Weekly, 2012
Recent discoveries have shed new light on the understanding of water metabolism: (1.) in addition to hypothalamic osmoreceptor cells expressing a TRPV1 variant, there are peripheral TRPV4 receptors sensing tonicity in the portal vein and changing ...

Clinical Efficiency of Vasopressin or Its Analogs in Comparison With Catecholamines Alone on Patients With Septic Shock: A Systematic Review and Meta-Analysis

open access: yesFrontiers in Pharmacology, 2020
BackgroundVasopressin is an efficient remedy for septic shock patients as its great capacity in promoting hemodynamic stabilization. The aim of current systematic review and meta-analysis is to compare the clinical efficiency of vasopressin or its ...
