The present invention provides oligopeptides, in particular, Ang-(1-7) derivatives, and methods for using and producing the same. In one particular embodiment, oligopeptides of the invention have higher blood-brain barrier penetration and/or in vivo half-life compared to the native Ang-(1-7), thereby allowing oligopeptides of the invention to be used in a wide variety of clinical applications including in treatment of cognitive dysfunction and/or impairment, pain, and traumatic brain injury.

The present invention relates, inter alia, to a method comprising administering to a subject having high output shock and undergoing treatment with a catecholamine at a dose equivalent to at least about 0.2 mcg/kg/min of norepinephrine a dose of angiotensin II which is effective to raise the blood pressure of the subject to a mean arterial pressure (MAP) of about 65 mm Hg or above, and which is effective to reduce the dose of the catecholamine required to maintain a MAP of about 65 mm Hg to the equivalent of about 0.05-0.2 mcg/kg/min norepinephrine or less, or to the equivalent of about 0.05 mcg/kg/min norepinephrine or less.

Subject matter of the present invention is a method for predicting or diagnosing a refractory shock in a subject that either runs into shock or that has developed shock, wherein said method is comprising the steps: determining the level of DPP3 in a sample of bodily fluid of said subject; comparing said level of determined DPP3 to a predetermined threshold,
wherein said subject is predicted to run into refractory shock or is diagnosed as having refractory shock if said determined level of DPP3 is above said predetermined threshold.

Further subject matter relates to vasopressors, angiotensin-receptor agonists and/or precursors thereof, inhibitors of the activity of DPP3 and anti-ADM antibodies for use in therapy of shock in a subject that either runs into shock or that has developed shock.

The present disclosure relates to the use of angiotensin II, angiotensin III, or angiotensin IV in therapeutic methods for the treatment of hypotension, especially catecholamine-resistant hypotension.

The present invention provides, among other things, methods and compositions for treating brain conditions. In some embodiments, the methods include administering to a subject suffering from or susceptible to a brain condition an angiotensin (1-7) peptide via either an intravenous or subcutaneous route of administration.

The present disclosures provides methods for decreasing injuries associated with intraoperative hypotension by intravenously administering to a subject a therapeutically effective amount of a fat emulsion, following a period of intraoperative hypotension and after the subject's mean arterial blood pressure has recovered. The disclosure also provides methods for preventing injuries associated with intraoperative hypotension, particularly for surgical candidates that have an increased risk for intraoperative hypotension. Non-limiting examples of injuries contemplated herein include myocardial injury, myocardial infarction, and acute kidney injury.

The present disclosure relates to the use of angiotensin II in therapeutic methods for the treatment of renal failure, especially renal failure associated with cirrhosis.
