Effects of Vasodepressor vs. Vasopressor Arms of Renin Angiotensin System on Renal Hemodynamic Regulation in Renal Ischemia-Reperfusion Injury; Sex Difference [PDF]

open access: yesمجله دانشکده پزشکی اصفهان, 2022
The exact mechanisms involved in acute renal injury (AKI) due to renal ischemia-reperfusion (IR) are not fully understood, although it has been shown that the renin-angiotensin system (RAS) may play an important role in IR-associated AKI.

Exploiting Knowledge on Structure–Activity Relationships for Designing Peptidomimetics of Endogenous Peptides

open access: yesBiomedicines, 2021
Endogenous peptides are important mediators in cell communication, being consequently involved in many physiological processes. Their use as therapeutic agents is limited due to their poor pharmacokinetic profile. To circumvent this drawback, alternative

Pathological Role of Angiotensin II in Severe COVID-19

open access: yesTH Open, 2020
The activated renin–angiotensin system induces a prothrombotic state resulting from the imbalance between coagulation and fibrinolysis. Angiotensin II is the central effector molecule of the activated renin–angiotensin system and is degraded by the ...

Temporal profile and mechanisms of the prompt sympathoexcitation following coronary ligation in Wistar rats [PDF]

open access: yes, 2014
Our aim was to assess the timing and mechanisms of the sympathoexcitation that occurs immediately after coronary ligation. We recorded thoracic sympathetic (tSNA) and phrenic activities, heart rate (HR) and perfusion pressure in Wistar rats subjected to ...
