INTRODUCTION AND OBJECTIVES Neprilysin breaks down numerous vasoactive peptides. The soluble form of neprilysin, which was recently identified in heart failure, is associated with cardiovascular outcomes. Within a multibiomarker strategy, we directly compared soluble neprilysin and N-terminal pro-B-type natriuretic peptide as risk stratifiers in a real-life cohort of heart failure patients. M...

Ultrasmall gold nanoparticles with a metallic core diameter of 2 nm were surface-conjugated peptides that selectively target epitopes on the surface WW domain model protein hPin1 (hPin1-WW). The binding to was accomplished via thiol group terminal cysteine. particles analyzed by NMR spectroscopy, high-resolution transmission electron microscopy, and differential centrifugal sedimentation. loadi...

INTRODUCTION AND OBJECTIVES Measurement of natriuretic peptides may be recommended prior to echocardiography in patients with suspected heart failure. Cut-off point for heart failure diagnosis in primary care is not well established. We aimed to assess the optimal diagnostic cut-off value of N-terminal pro-B-type natriuretic peptide on a community population attended in primary care. METHODS ...

We tested the capacity of antibodies RB733, RB734, RB766, RB767, RB768, RB769, RB770, RB771, RB772 and RB773 to recognize by ELISA three different molecular forms human cardiac troponin T isoform 6 (cTnT): an N-terminal peptide (Nter-cTnT), full-length cTnT protein (FL-cTnT) I-T-C complex (ITC-complex). Our results show that RB734 specifically recognizes region as well alone ITC-complex. or in ...

Cleavage of hemagglutinin precursor (HA0) by cellular proteases results in the formation of two subunits, HA1 and HA2. The N-terminal fragment of HA2, named a fusion peptide (HAfp), possess a charged, amine N-terminus. It has been shown that the N-terminus of HAfp stabilizes the structure of a helical hairpin observed for a 23-amino acid long peptide (HAfp1-23), whose larger activity than HAfp1...

Dinitrophenylation-The amino-terminal residue was determined on. a sample of the peptide before desalting. Approximately 1 pmole of the peptide was submitted to dinitrophenylation for 6 hours with the reaction mixture maintained at pH 8.5 with the aid of a pH stat. The solution was evaporated to dryness and triturated with dry ethyl acetate. Estraction was continued until all the yellow color w...
