The downstream angiotensins Ang1-5 and Ang3-8 showed significantly higher concentrations in the ARB and ARNI groups compared with the ACE-I group owing to an increased supply with Ang1-8.
Although patients with diminished ARC as well as undetectable angiotensins should not benefit from RAS blockade, angiotensin profiles of patients with excessive ARC should improve by an additional RAS-blocker therapy.
Response to angiotensins I and II and to AI-converting-enzyme inhibitor in a shark.
These authors further noted that although lampreys appear to lack genes coding for angiotensinogen and renin, plasma angiotensin II (ANGII) doubles in response to volume depletion, indicating an early Paleozoic appearance of the important role of ANGII in fluid homeostasis.
Plasma angiotensins under sustained converting enzyme inhibition with enalapril in normal humans.
The impact and the physiological significance of the balance of renal ACE/ACE2 activities cannot be understood without assessing the tissue concentration of angiotensins. Regarding Ang I it is interesting to note that despite the significant reduction in renin activity in 3 copies control mice (compared to 1 copy) our data evidenced a greater increase in the concentration of Ang I in kidney homogenates of this group compared to 1 copy control mice (Figure 5(a) and Table 2).

Blood pressure is controlled by hormones called angiotensins which constrict blood vessels.
The vascular endothelial cells contain a large amount of ACE and can synthesize angiotensins via the local renin-angiotensin system (Kifor and Dzau 1987).
Retained angiotensins were eluted with 0.8 mL of methanol into polypropylene tubes coated with the Tris-albumin buffer.

On the other hand, a temperature optimum could be artificially created, if at a temperature >45 [degrees]C the angiotensin were broken down by increased activities of proteolytic enzymes present in the samples.
