Production and clearance of plasma C-type natriuretic peptide (CNP) and amino terminal (NT)-proCNP immunoreactivity in the human circulation remain poorly characterized. Accordingly, we have measured arterial and venous concentrations of CNP and NT-proCNP across multiple tissue beds during cardiac catheterization in 120 subjects (age: 64.2+/-9.0 years; 73% men) investigated for cardiovascular d...

Abstract Background: Achondroplasia (ACH) is the most common skeletal dysplasia and frequent form of dwarfism. ACH caused by a gain-of-function mutation in fibroblast growth factor receptor 3 (FGFR3) gene results impairment endochondral ossification processes. C-type natriuretic peptide (CNP) promotes chondrocyte development through inhibition FGFR3 pathway, specifically activation NPRB. CNP de...

PURPOSE. To evaluate the potential neuroprotective effects of C-type natriuretic peptide (CNP) on rat retinal ganglion cells (RGCs). METHODS. Cultured adult rat retinal cells were treated with vehicle, CNP, or atrial natriuretic peptide (ANP), followed by cytotoxic insults (glutamate, TNFalpha, or withdrawal of trophic factor). RGC survival was analyzed by counting Thy-1-positive cells in each ...

The Federal Reserve Banks of Boston and Atlanta convened a meeting of the Mobile Payments Industry Workgroup (MPIW) in November 2015 to discuss payments in the card-not-present (CNP) environment. Not only are consumers increasingly using mobile devices to initiate CNP payments; but the e-commerce fraud rate in the U.S. is expected to increase significantly as EMV2 chip card migration progresses...

In adult rat testes, the blood-testis barrier (BTB) in the seminiferous epithelium must "open" (or "disassemble") to accommodate the migration of preleptotene spermatocytes from the basal to the adluminal compartment that occurs at stage VIII of the epithelial cycle. However, the molecule(s) and/or mechanism(s) that regulate this event are unknown. In this report, C-type natriuretic peptide (CN...

Protected areas of northern Botswana such as the Okavango Delta (OD) or Chobe National Park (CNP) are well-known hot spots for the conservation of African wildlife. However, their infection status regarding bovine tuberculosis (BTB) at the domestic/wildlife interface has never been investigated. To provide preliminary baseline data on the circulation of Mycobacterium bovis in those sites, we pe...

OBJECTIVE Chlorpyrifos (CP) as an organophosphorus pesticide is thought to induce oxidative stress in human cells via producing reactive oxygen species (ROS) that leads to the presence of pathologic conditions due to apoptosis along with acetylcholinesterase (AChE) inhibition.This study aimed to evaluate the apoptotic effects of CP and to assess the protective potential of CeO2nanoparticle (CNP...

BACKGROUND Short half-life and low levels of growth factors in the niche of injured microenvironment necessitates the exogenous and sustainable delivery of growth factors along with stem cells to augment the regeneration of injured tissues. METHODS Here, recombinant human hepatocyte growth factor (HGF) was incorporated into chitosan nanoparticles (CNP) by ionic gelation method and studied for...

In experimental animals, C-type natriuretic peptide (CNP) has vasodilating, hypotensive, and natriuretic activities. The role of circulating CNP in the overall regulation of cardiac and renal function in humans is less defined, in both health and disease. We measured cardiac volumes, diastolic and systolic functions, systemic (Doppler echocardiography) and renal hemodynamics, intrarenal sodium ...
