Oral administration of endogenous substances in most cases results in negligible net increases in baseline plasma concentrations, associated with high variability.
After the last dose administration, the endogenous antioxidants and lipid peroxidation were estimated in heart tissue homogenate.
Intake of exogenous E2, particularly by systemic administration, increases endogenous plasma E2 and suppresses plasma FSH toward premenopausal levels [ 7].
There are a number of potential explanations for the observed effect of DrotAA administration on endogenous protein C levels.
The exogenous administration or endogenous expression of human growth factors or cytokines in these mice has improved both maintenance and reconstitution and holds future promise for the optimization of humanized mice.
iNO administration reduces endogenous NO production, and therefore rapid withdrawal of iNO can cause a significant rebound pulmonary hypertension, but in clinical practice, this can be avoided by gradual withdrawal [ 2].
In the present study, prednisolone acetate was administered to finishing bulls and cows according to a therapeutic protocol (2 × 0.4-0.5 0.4-0.5w i.mg/kg 48 h interval) to further verify the practical impact of this cut-off limit and develop sound strategies to distinguish bwtween exogenous admi.mstration and endogenous production.
Alternatively, locally depleted endogenous cytoprotective prostaglandins may be replaced by the administration of prostaglandin E1 analogues, such as misoprostol.
Binge ethanol administration significantly enhanced endogenous lipid peroxidation and caused an enhanced in vitro susceptibility to lipid peroxidation.
The administration of the endogenous NMDA-receptor antagonists, KYNA and its derivative KYNAA2, resulted in the inhibition of the induced signaling system of the TG, which further points the importance of the glutamate receptors in this mechanism.
This novel hybrid technique has many workflow advantages; however, one of the essential prerequisites for its clinical acceptance is that semi-quantitative PET measures such as standardized uptake values (SUV) are not altered by the endogenous administration of intravenous or oral contrast agents such as gadolinium-based contrast agents (GBCA) or iron oxide-based contrast agents.
