An antigen with an increased half-life is provided for the formulation of more stable and consistent clinical diagnostic immunoassay controls and calibrators. An antigen analogue comprises a first and a second polypeptide which is identical or similar to corresponding terminal amino acid sequences of an antigen. The first and second polypeptides are connected with a PEG chain. Also provided are methods of calibrating assays using a compound disclosed herein.

This disclosure relates to anti-Natriuretic Peptide Receptor 1 (NPR1) antibodies including agonist antibodies which are able to activate the NPR1 receptor, pharmaceutical compositions comprising the same, and methods of treatment comprising the same.

The present invention provides methods of treating the early stages of COVID-19 infection in a patient in need thereof. The methods comprise administering a therapeutically effective amount of a drug that increases signaling through the GC-A receptor, or a pharmaceutically acceptable salt thereof, to a patient in need thereof. In certain aspects, the drug is a NEP inhibitor, a GC-A receptor agonist, or a pharmaceutically acceptable salt thereof. In certain embodiments, the methods of the present invention prevent the progression from the early stages of COVID-19 infection to hypoxemia, acute respiratory distress syndrome (ARDS) or death. In certain embodiments, the methods of the present invention prevent the development of pulmonary dysfunction after developing early symptoms of COVID-19 infection or the progression from mild to severe hypoxemia in these patients.

This document provides methods and materials involved in assessing mammals with acute decompensated heart failure (ADHF), as well as methods and materials involved in assessing outcomes. For example, methods and materials for using the level of plasma CNP and the level of urinary CNP to determine whether or not a mammal is developing or likely to develop more severe ADHF, as well as methods and materials for using the level of plasma CNP and the level of urinary CNP to identify patients having an increased likelihood of experiencing a poor outcome are provided.

The present disclosure, relates, in general, to stable variants of C-type natriuretic peptide (CNP) and uses thereof to treat bone-related disorders.

This document provides methods and materials for using natriuretic polypeptides to reduce the generation of kidney cysts, to reduce the number of kidney cysts, to reduce the size of kidney cysts, and/or to reduce the weight of a mammal's kidneys in mammals with polycystic kidney disease. For example, methods and materials for using natriuretic polypeptides (e.g., BNP) and/or nucleic acid encoding natriuretic polypeptides to reduce kidney cystogenesis and to reduce kidney organ to body weight ratios in mammals with mammals with polycystic kidney disease (e.g., autosomal recessive polycystic kidney disease) are provided.
